Chromatin is not randomly organized inside the eukaryotic nucleus in interphase. In budding yeast gene expression of some specific loci is affected by their positioning in the nucleus. Replication firing of early origins is also correlated to the position of the respective ARSs (Autonomously Replicating Sequences) in the nucleus. However, the relationship between nuclear positioning and DNA processes is not yet fully understood. To study the importance of chromosome positioning in nuclear processes and cell physiology, we use budding yeast strains carrying fused chromosomes, which are expected to dramatically change the chromosomes configuration in interphase. By combining microscopy and computational modeling we show that the chromosomes arrangement in strains carrying fused chromosomes is greatly modified. Despite the reorganization of chromosomes in the nucleus, our functional experiments show that transcriptional activity, replication timing and response to stress conditions are not affected. The results, thus, indicate that the function of the genome is mostly independent of chromosome positioning in the budding yeast nucleus.
La cromatina no está distribuida de manera aleatoria dentro del núcleo eucariota en interfase. En la levadura Saccharomyces cerevisiae la expresión de algunos genes específicos depende de su posición en el núcleo. El inicio de los orígenes de replicación está también correlacionado a la posición de las respectivas ARSs (Autonomously Replicating Sequences) en el núcleo. Sin embargo, la relación entre posición nuclear y los procesos del ADN no está completamente aclarado. Para estudiar la importancia de la posición de los cromosomas en las actividades nucleares y en la fisiología celular, hemos utilizado cepas de S. cerevisiae con fusiones cromosómicas, en las que la conformación cromosómica típica de la levadura cambia drásticamente. Mediante la combinación de la microscopía y de los modelos computacionales mostramos que la organización cromosómica en las cepas que llevan cromosomas fusionados está ampliamente modificada. Aunque la organización de los cromosomas está modificada, nuestros experimentos funcionales muestran que la actividad transcripcional, el tiempo de replicación y la respuesta a condiciones de estrés no se muestran alterados. Por consiguiente, los resultados indican que la función del genoma es principalmente independiente de la posición de los cromosomas en el núcleo de la levadura Saccharomyces cerevisiae.

This dissertation extends and contributes to the extant literature on social enterprise by examining the enterprise-beneficiary relationship in social enterprises with particular focus on performance measurement and social value creation. Ironically, while social missions and commitment to beneficiaries is what distinguishes social entrepreneurship from traditional entrepreneurship, little research has been conducted to examine this relationship. Utilizing a portfolio of 101 social enterprises based in New England, this study consisted of two phases: the development of a typology of social enterprise based on the enterprise-beneficiary relationships present in the portfolio, and a comparative case study closely examining six cases of social enterprise across the typology.

By examining beneficiary positioning, level of interaction, and relationship characteristics four archetypes of social enterprise were identified: general benefit enterprises, philanthropic enterprises, social business enterprises, and relational social enterprises. Examining these models, the concept of entwinement emerged. I define entwinement as the mutual reliance and commitment between two parties, in these cases the enterprises and the individual beneficiaries they seek to serve. These models fall along a continuum of entwinement, ranging from no entwinement in the general benefit enterprises to high entwinement in the relational social enterprises. By examining two cases each of philanthropic enterprises, social business enterprises and relational enterprises I found that entwinement has positive implications for stakeholder salience and depth of impact for individual beneficiaries. I also found that while funding requirements are a key driver of the development of formalized social performance measurement programs, the level of entwinement moderates that relationship.

This dissertation contributes directly to stakeholder theory and to the social entrepreneurship literature. It offers an explanation for how managers recognize the salience of their stakeholder groups by raising entwinement as a key mechanism through which managers recognize the legitimacy and power of the beneficiary group. By utilizing the capabilities approach from the development literature, this study also presents a framework through which depth of impact can be examined across issue are and business model design. Finally, this paper identified funder requirements as a key driver of social performance measurement systems, suggesting that even as social enterprises diversify their revenue streams and business models they still bear significant semblance to non-profit organizations.

Increased bus patronage has the potential to facilitate the achievement of transport sustainability in cities in the developed and developing countries by alleviating congestion and its consequences including delays and pollution. However, this requires bus-friendly policies and a significant improvement in the efficiency of urban bus operations. Such operations consist of a large number of location based services such ‘countdown’ which requires the computation of bus arrival times at bus stops. However, to date there is a lack of agreement globally on the location based services and their key performance indicators expressed in the form of the required navigation performance parameters of accuracy, integrity (quality of or confidence in the position accuracy), continuity of service, and service availability. As a result of this, there is currently no optimal positioning system specification for bus operations. This thesis addresses these two issues and contributes to the field by firstly creating a comprehensive list of location-based services together with the required navigation performance for some of the applications. This is through a comprehensive literature review, consultation with a subject matter expert, and augmentation with, for the first time, a global survey of the major bus operators. Secondly, by demonstrating that a significant improvement in positioning accuracy is achievable with multi-constellation differential positioning. This is achieved through a comparative analysis of GPS only and augmentation with GLONASS and local differential positioning. Thirdly, the benefits of the new signals are demonstrated in the measurement and position domains, using established and novel mathematical models. The thesis analyses in detail the measurement qualities of the legacy and new signals in the measurement and position domains. The results of the former demonstrate the superiority of the L5 signal both in terms of signal strength and measurement precision, over the legacy L1 coarse acquisition (C/A) code measurements, with the new L2C as the weakest. The results of the position domain analysis show a significant improvement in positioning accuracy over the use L1 C/A code measurements alone, as a result of the mitigation of the ionospheric error through the combined use of the L1 C/A and L2C code measurements. The improvements in 3D positioning accuracy at the 95th percentile range from 22% (6m) in the clean (unobstructed environment) to 48% (13.66m) in the urban environment. The corresponding 2D horizontal positioning accuracy at the 95th percentile are 3.33m and 9.03m respectively. These improvements would not only enable more of the location based services to be supported but also facilitate the achievement of higher accuracy performance when using carrier phase measurements through enhanced ambiguity resolution.

Modules modalities (landscape or portrait mounting) affect the losses related to partial shading by changing the internal circuital modules orientation. This partial shading is responsible up to 25% of output production losses in large-scale ground-mounted photovoltaic power plants (Mao, Sunan, Peng, Yanlong, & Weiping, 2017). Previous studies succeed in demonstrating, modelling and analyzing the link between module modalities and technical performance losses, putting the emphasis on the electrical effect. Nonetheless, the complexity of the non-linear behavior of modules under partial shading conditions limits detailed studies in reducing studied arrays sizes, neglecting some technical and economic issues of PV project development. Using a dynamic simulation model on PVsyst, this study proposes a simplified method to analyze the social, technical and economic impact of the positioning of modules on a French large-scale ground-mounted PV plant with fixed-mounting structures through a case study. Three positionings are studied: 2 portrait modules, 4 landscape modules and 6 landscape modules. This study provides the following contributions: (i) integrate geometric considerations related to modules orientation (ii) analyze modules positioning impact under different Ground Coverage Ratios and modules interconnections at the scale of a photovoltaic power plant (iii) translate the impact of modules positioning into socio-economic indicators (LCOE, NPV, IRR).
Modulpositionering (landskaps- eller porträttmontering) påverkar förlusterna i samband med partiell skuggning, vilket svarar för upp till 25% av produktionstabellerna i storskaliga fotovoltaiska kraftverk (Mao, Sunan, Peng, Yanlong & Weiping, 2017). Tidigare studier lyckas demonstrera, modellera och analysera länken mellan modulmodaliteter och tekniska prestandaförluster, vilket understryker den elektriska effekten. Inte desto mindre begränsar komplexiteten hos modulernas icke-linjära beteende under partiella skuggningsförhållanden detaljerade studier för att minska de studerade storlekarna för storleken, försumma de tekniska och ekonomiska realiteterna för PV-projektutveckling. Med en dynamisk simuleringsmodell som approximeras på PVsyst, föreslår denna studie metod för att analysera de sociala, tekniska och ekonomiska konsekvenserna av positionering av moduler på en fransk storskalig jordmonterad PV-anläggning genom en fallstudie. Tre modaliteter studeras: 2 porträttmoduler, 4 landskapsmoduler och 6 landskapsmoduler. Denna studie ger följande bidrag: (i) integrera geometriska överväganden relaterade till modulorientering (ii) analysera moduler positioneringspåverkan under olika markdäckningsförhållanden och moduler sammankopplingar i en fotovoltaisk kraftverks skala (iii) översätta inverkan av modulpositionering i socioekonomiska indikatorer (LCOE, NPV, IRR).

Chez les Mammifères, le succès de la fécondation et d’un développement embryonnaire viable résident principalement dans la qualité des cellules reproductrices : les gamètes mâles (spermatozoïdes) et femelles (ovocytes) apportant chacun la moitié du patrimoine génétique du futur individu. Dès lors que ce patrimoine génétique est endommagé par différents processus tels que les attaques radicalaires communément appelées stress oxydant, cela peut compromettre la qualité des gamètes et par conséquent le succès de la reproduction. En effet, les dommages oxydants à l’ADN spermatique sont une des causes d’infertilité masculine fréquemment associés aux échecs reproductifs dans le cadre de conception naturelle ou artificielle chez l’homme. Afin de mieux appréhender l’impact des dommages oxydants sur la qualité des spermatozoïdes, notre équipe a généré des modèles murins présentant des atteintes oxydantes de l’ADN associées à des échecs reproductifs. Dans un de ces modèles nous avons pu montrer que tout le noyau spermatique n’était pas concerné de la même façon par les altérations oxydantes. De même, à l’échelle des chromosomes murins les investigations de l’équipe suggéraient que tous n’étaient concernés de la même façon. Dans ce travail de thèse, j’ai développé et mis en œuvre des protocoles d’hybridation in situ en fluorescence (FISH) permettant de montrer que la susceptibilité des chromosomes à l’oxydation est déterminée par la position des chromosomes dans le noyau spermatique murin. En parallèle de cette étude, je me suis intéressé à l’épigénome spermatique et plus particulièrement à la méthylation de l’ADN en conditions de stress oxydant. Les résultats préliminaires montrent qu’un environnement post-testiculaire pro-oxydant peut altérer le profil épigénétique spermatique. Dans un développement pré-clinique du sujet, j’ai contribué à montrer qu’une supplémentation orale antioxydante permettait de corriger les dommages oxydants à l’ADN, en modifiant la réponse antioxydante globale du tissu épididymaire des animaux
In Mammals, the success of fertilization and embryonic development, are associated to the quality of the reproductive cells: male gametes (spermatozoa) and female gametes (oocytes); each bringing half of the genetic heritage of the future individual. This genetic heritage may be compromised by various processes a very common one being radical attacks in cases of oxidative stress, it could diminish the quality of gametes and therefore the success of reproduction. It is well described that sperm DNA oxidative damage (SDOD) is one of the causes of male infertility frequently associated with reproductive failures in the context of natural or artificial conception in humans. To better understand the impact of oxidative damage on the quality of sperm, our team generated mouse models with SDOD. Characterization of these transgenic mice has shown that SDOD alone was associated with increased embryo defects, miscarriages and perinatal mortality. The team also brought forward that SDOD concerns preferentially specific regions of the sperm nucleus. In addition, the team suggested that sperm chromosomes were not identically susceptible to oxidative damage.In this thesis work, I developed and implemented fluorescence in situ hybridization (FISH) protocols to study chromosome positioning in the mouse sperm. I confirmed that susceptibility of chromosomes to oxidation is determined by their position in the murine sperm nucleus. In parallel, I addressed the question whether the sperm epigenome (particularly DNA methylation) was modified in a situation of post-testicular oxidative stress. Preliminary results seem to show that SDOD disturbs the sperm epigenetic profile.In parallel, in a pre-clinical approach, I contributed to show that an oral antioxidant supplementation can correct SDOD by modifying the antioxidant response of the epididymal tissue of the treated animals

The use of electronic monitoring (EM) as a tool to supervise high-risk offenders has increased in the field of criminal justice in the state of Texas. Although EM is now widely used to supervise high-risk offenders to prevent them from committing further crimes, it is unclear whether EM has achieved the purpose of reducing reoffenses during parole supervision. Hirschi's social bond theory, which was later developed into social control theory, was used as the framework for this general qualitative study to explore retired parole officers' perceptions concerning whether EM is successful in preventing high-risk offenders from committing additional crimes. Interview data were collected from 10 retired parole officers who supervised high-risk offenders on EM in Harris County, Texas. The findings revealed that the 10 officers perceived EM to be an effective tool, but they perceived the role of capitalizing on positive social bonds was equally important in controlling criminal behavior. Specifically, the officers perceived that their bond with the high-risk offenders on EM could diminish offenders' propensity to commit new crimes. Opportunities for positive social change stemming from this study include recommendations to the Texas Department of Criminal Justice to develop policies and training that is consistent with social bond theory, and retrain parole officers to emphasize to offenders positive contacts and relationship with family and continuing employment during the term of parole release in order to reduct opportunities for reoffense and futher victimization to the community.

U.S. Army Corps of Engineers (USACE) regulates fill of jurisdictional waters of the United States including wetlands. Recent USACE regulations set a threshold of impacts to wetlands at one-half acre. Impact area can be determined by Global Positioning System (GPS) measurement of wetland boundary and Geographic Information System (GIS) calculation of impact area. GPS point selection methods include (1) equal time interval, (2) transect and (3) intuition. Four two-acre shapes were measured with each GPS method and brought into GIS for area calculation. Analysis of variance and Root Mean Square Error analyses determine that the transect method is an inferior point selection method in terms of accuracy and efficiency.

Population ageing is one of the major challenges of the 21st century and societies need to optimize opportunities for active ageing. This thesis explored how the built environment impacts the mobility and participation within the community. A combination of person-based GPS tracking and in-depth interviews was used to collect data on transportation use and engagement in activities of older people living within Brisbane. It showed that the built environment has a strong impact on mobility. To enable healthy and active ageing modern communities need to overcome car dependency and provide mobility options that are tailored towards older people’s needs.

L’érosion des sentiers de moyenne montagne auvergnate est étudiée dans cette thèse à travers l’évolution morphologique de quatre secteurs présentant des stades d’érosion et des rythmes d’évolution différents, répartis dans le Massif du Sancy et la Chaîne des Puys. Notre approche méthodologique repose sur le croisement de trois jeux de données inédits collectés sur le terrain : relevés topographiques, données climatiques et cartographie du comportement des randonneurs. Les relevés topographiques fins mobilisent trois méthodes complémentaires de collecte de données (lasergrammétrie, GPS différentiel et relevés manuel). L’analyse croisée de l’ensemble de ces données nous a permis de : (1) quantifier des volumes d’érosion et de dépôt ; (2) cartographier les secteurs les plus sensibles à l’érosion ; (3) identifier une saisonnalité des processus érosifs ; (4) proposer un outil d’aide à la gestion des sentiers.Nos résultats de quantification de l’érosion des sentiers indiquent une différenciation des secteurs étudiés. Ce gradient d’érosion constaté s’explique par : le contexte climatique local qui commande la saisonnalité des processus d’érosion, la fréquentation touristique inégale et l’érodabilité du substrat. En réponse à cette érosion, nous avons observé la mise en place de divers aménagements (fils guide, fascines, murets, rigoles d’évacuation…), globalement efficaces. Néanmoins, il apparaît qu’un affinement du positionnement de ces derniers, sur la base d’une compréhension des processus érosifs sur un temps plus long, optimiserait le rôle protecteur de ces ouvrages
In this thesis, weathering of hiking trails has been studied in the low mountain ranges of the Massif Central (Auvergne, France) through the morphological comparison of four sectors in the Massif du Sancy and the Chaîne des Puys, each one presenting different erosion stages and rhythms of evolution. Our methodological approach is based on the crossing of three unpublished field datasets: topographic data, climate data and cartography of hiker behavior. High resolution topographic data mobilized three complementary data collection methods (terrestrial laser scanning, GPS monitoring and manual monitoring). Cross-analysis of all these data allowed us to: (1) quantify erosion and depositional volumes; (2) map the weathering sensitivity of studied areas; (3) identify the seasonality of weathering processes; (4) propose an operational evaluation tool for the management of hiking trails in low mountain ranges. Weathering quantification results show a clear differentiation of the studied areas. This contrasting erosion gradient has been proved to be linked to: local bioclimatic parameters which command the seasonality of weathering processes, irregular touristic attendance and substratum durability. In response to this erosion, varied management were introduced (guideline, wattle fence, low wall, water bars ...) and globally effective. Nevertheless, it appears that a refinement of the positioning adjustments, based on an understanding of weathering processes over a longer period would optimize the protective role of these structures

Purpose This thesis is about liveability, place and ageing in the high density urban landscape of Brisbane, Australia. As with other major developed cities around the globe, Brisbane has adopted policies to increase urban residential densities to meet the main liveability and sustainability aim of decreasing car dependence and therefore pollution, as well as to minimise the loss of greenfield areas and habitats to developers. This objective hinges on urban neighbourhoods/communities being liveable places, which residents do not have to leave for everyday living. Community/neighbourhood liveability is an essential ingredient in healthy ageing in place and has a substantial impact upon the safety, independence and well-being of older adults. It is generally accepted that ageing in place is optimal for both older people and the state. The optimality of ageing in place generally assumes that there is a particular quality to environments or standard of liveability in which people successfully age in place. The aim of this thesis was to examine if there are particular environmental qualities or aspects of liveability that test optimality and to better understand the key liveability factors that contribute to successful ageing in place. Method A strength of this thesis is that it draws on two separate studies to address the research question of what makes high density liveable for older people. In Chapter 3, the two methods are identified and differentiated as Method 1 (used in Paper 1) and Method 2 (used in Papers 2, 3, 4 and 5). Method 1 involved qualitative interviews with 24 inner city high density Brisbane residents. The major strength of this thesis is the innovative methodology outlined in the thesis as Method 2. Method 2 involved a case study approach employing qualitative and quantitative methods. Qualitative data was collected using semi-structured, in-depth interviews and time-use diaries completed by participants during the week of tracking. The quantitative data was gathered using Global Positioning Systems for tracking and Geographical Information Systems for mapping and analysis of participants’ activities. The combination of quantitative and qualitative analysis captured both participants’ subjective perceptions of their neighbourhoods and their patterns of movement. This enhanced understanding of how neighbourhoods and communities function and of the various liveability dimensions that contribute to active ageing and ageing in place for older people living in high density environments. Both studies’ participants were inner-city high density residents of Brisbane. The study based on Method 1 drew on a wider age demographic than the study based on Method 2. Findings The five papers presented in this thesis by publication indicate a complex inter-relationship of the factors that make a place liveable. The first three papers identify what is comparable and different between the physical and social factors of high density communities/neighbourhoods. The last two papers explore relationships between social engagement and broader community variables such as infrastructure and the physical built environments that are risk or protective factors relevant to community liveability, active ageing and ageing in place in high density. The research highlights the importance of creating and/or maintaining a barrier-free environment and liveable community for ageing adults. Together, the papers promote liveability, social engagement and active ageing in high density neighbourhoods by identifying factors that constitute liveability and strategies that foster active ageing and ageing in place, social connections and well-being. Recommendations There is a strong need to offer more support for active ageing and ageing in place. While the data analyses of this research provide insight into the lived experience of high density residents, further research is warranted. Further qualitative and quantitative research is needed to explore in more depth, the urban experience and opinions of older people living in urban environments. In particular, more empirical research and theory-building is needed in order to expand understanding of the particular environmental qualities that enable successful ageing in place in our cities and to guide efforts aimed at meeting this objective. The results suggest that encouraging the presence of more inner city retail outlets, particularly services that are utilised frequently in people’s daily lives such as supermarkets, medical services and pharmacies, would potentially help ensure residents fully engage in their local community. The connectivity of streets, footpaths and their role in facilitating the reaching of destinations are well understood as an important dimension of liveability. To encourage uptake of sustainable transport, the built environment must provide easy, accessible connections between buildings, walkways, cycle paths and public transport nodes. Wider streets, given that they take more time to cross than narrow streets, tend to .compromise safety - especially for older people. Similarly, the width of footpaths, the level of buffering, the presence of trees, lighting, seating and design of and distance between pedestrian crossings significantly affects the pedestrian experience for older people and impacts upon their choice of transportation. High density neighbourhoods also require greater levels of street fixtures and furniture for everyday life to make places more useable and comfortable for regular use. The importance of making the public realm useful and habitable for older people cannot be over-emphasised. Originality/value While older people are attracted to high density settings, there has been little empirical evidence linking liveability satisfaction with older people’s use of urban neighbourhoods. The current study examined the relationships between community/neighbourhood liveability, place and ageing to better understand the implications for those adults who age in place. The five papers presented in this thesis add to the understanding of what high density liveable age-friendly communities/ neighbourhoods are and what makes them so for older Australians. Neighbourhood liveability for older people is about being able to age in place and remain active. Issues of ageing in Australia and other areas of the developed world will become more critical in the coming decades. Creating livable communities for all ages calls for partnerships across all levels of government agencies and among different sectors within communities. The increasing percentage of older people in the community will have increasing political influence and it will be a foolish government who ignores the needs of an older society.

Il panorama dell'istruzione superiore in Russia è cambiato in modo significativo nel corso degli anni 2010 grazie all'attuazione dell'iniziativa di eccellenza Progetto 5-100. L'iniziativa è stata lanciata per aumentare la competitività globale di un gruppo di università russe. In precedenza, alcuni studi avevano riportato una crescita degli indicatori associati alla dimensione internazionale per i partecipanti al Progetto 5-100, mentre in pochi avevano considerato le percezioni del personale universitario e mostrato come le università hanno vissuto il processo di rapida internazionalizzazione. La tesi indaga l'impatto del Progetto 5-100 sull'evoluzione del posizionamento internazionale dell'Università Federale degli Urali e di tre delle sue unità accademiche. Queste ultime sono state scelte sulla base della loro performance durante la prima fase del Progetto 5- 100. Il presente lavoro evidenzia anche come l'internazionalizzazione sia stata riposizionata durante e in conclusione dell'iniziativa di eccellenza nel 2020 per quanto riguarda i criteri, le strategie di ricerca e didattica e i servizi. La tesi costruisce tre casi studio corrispondenti a tre rispettive unità accademiche sulla base dell'analisi tematica di interviste a 53 partecipanti allo studio e dell'analisi documentale dei piani strategici. La ricerca è supportata dal Rationales Prioritization Exercise (Lewis, 2007; di seguito RPE) e dall'analisi del contesto. Lo studio adotta la teoria del posizionamento (van Langenhove & Harré, 1999) come prospettiva teorica, considerando i documenti strategici e le interviste con i partecipanti allo studio come cornice contestuale. La definizione di internazionalizzazione di de Wit et al. (2015) è stata utilizzata come quadro concettuale: l'internazionalizzazione è intesa come un processo intenzionale che migliora la qualità dell'istruzione e della ricerca e coinvolge tutti gli studenti e il personale al fine di contribuire alla società. Le conclusioni dimostrano che le tre unità accademiche hanno scelto strategie diverse di internazionalizzazione all'interno dello stesso contesto dato dal Progetto 5-100, ma il loro posizionamento internazionale si è evoluto in modo simile proprio grazie all'iniziativa di eccellenza. La ricerca illustra che l'Università Federale degli Urali ha compiuto un cambiamento significativo verso la comprensione dell'internazionalizzazione così come definita da de Wit et al. (2015) e l'ha riposizionata a livello universitario. Infatti, l'internazionalizzazione nell'Università Federale degli Urali è passata dall’essere un insieme di attività specifiche a un processo intenzionale e parte integrante della vita accademica dell'università. La tesi dimostra inoltre che le unità accademiche hanno riposizionato l'internazionalizzazione in un modo da corrispondere alle loro caratteristiche uniche e strategie adottate.
The landscape of higher education in Russia significantly changed during 2010s due to the implementation of the excellence initiative Project 5-100. The initiative was launched in order to increase the global competitiveness of a group of Russian universities. Previous research had reported a growth in indicators associated with the international dimension for the participants of Project 5-100, while little research had considered the perceptions of university staff and shown how universities experienced the process of rapid internationalization. The thesis investigates the impact of Project 5-100 on the evolution of the international positioning of Ural Federal University and three of its academic units. These were chosen on the basis of their performance during the first half of Project 5-100. The present work also uncovers how internationalization was repositioned during the excellence initiative with regard to rationales, research and educational strategies, and services by the end of the excellent initiative in 2020. The thesis constructs three case studies of respective academic units based on the thematic analysis of interviews with 53 study participants and the document analysis of Strategic Plans. The research is supported by the Rationales Prioritization Exercise (Lewis, 2007; hereon RPE) and analysis of the context. The study adopts positioning theory (van Langenhove & Harré, 1999) as a theoretical lens where strategic documents and interviews with the study participants are considered as discourse. The definition of internationalization by de Wit et al. (2015) is used as a conceptual framework, where internationalization is understood as an intentional process that enhances the quality of education and research and involves all students and staff in order to contribute to society. The conclusions demonstrate that three academic units have chosen different strategies of internationalization within the same given context of Project 5-100, but their international positioning evolved in a similar way due to the timeframe of the excellence initiative. The research illustrates that Ural Federal University has made a significant shift towards understanding internationalization as defined by de Wit et al. (2015) and it has repositioned it at university level. Indeed, internationalization in Ural Federal University went from a set of specific activities to an intentional process and an integral part of the academic life of the university. The research also shows that the academic units repositioned internationalization in a way which matched their unique features and chosen strategies.

Appropriate component alignment is critical for improving stability, maximising bearing performance and restoring native biomechanics after total hip arthroplasty (THA). Due to the large variation in patient morphology and pelvic kinematics, current technologies lack definition of what constitutes the optimal target alignment for an individual. Analyses of large series of problematic THAs confirm that apparently well-orientated components on standard radiographs can still fail due to functional component malalignment. Evidently, previously defined “safe zones” are not appropriate for all patients as they do not consider the dynamic behaviour of the hip joint. The first goal of this thesis was to understand the variation in patients’ pelvic kinematics to demonstrate the clinical importance of functional cup orientation. Secondly, the variation in femoral morphology across the THA population was investigated in consideration of how that might affect femoral component positioning. From these findings, a commercially-scalable method of analysing each patient’s individual hip dynamics prior to THA was developed. This enabled an optimal component alignment to be chosen for each patient, accounting for their specific morphology and dynamics. Finally, we developed a simple intraoperative method to achieve the predetermined optimal alignment utilising 3D printed custom guides. The end result is the Optimized Positioning System™ (OPS™), comprising preoperative dynamic planning and patient-specific instrumentation for delivery of a patient’s optimal component alignment. The technology has been commercialised globally and used in over 5,000 primary total hip replacements to date.

Contexte : le soin peau-à-peau est actuellement une pratique de soin courant au sein des services de médecine néonatale. Il constitue une opportunité relationnelle unique qui peut être proposée très rapidement après la naissance prématurée et qui a déjà montré de nombreux bénéfices pour le nouveau-né prématuré et ses parents. Ce soin comme tout autre soin reste améliorable et ajustable au contexte de haute technologie des pays industrialisés afin notamment de créer une niche sensorimotrice et relationnelle optimale. Objectif : l'objectif de la recherche action réalisée dans le cadre de ce doctorat vise précisément à tester l'apport d'un changement d'installation lors du peau-à-peau en réanimation néonatale. L'hypothèse défendue est que l'installation novatrice en Flexion Diagonale Soutenue (FDS) serait une voie d'amélioration non seulement en termes d'opportunité interactionnelle individualisée parent-bébé, mais également en termes de soutien à la construction de la parentalité mise à mal par la naissance prématurée et en termes de prévention posturale et motrice du nouveau-né prématuré. Méthode : nous avons mené une recherche interventionnelle monocentrique prospective cas-contrôle. Quarante-deux grands prématurés nés entre 27 et 32 semaines et leurs mères ont été inclus de mai 2015 à juillet 2016, répartis dans deux groupes : le groupe 1 avec l'installation en peau-à-peau couramment pratiquée in situ, soit verticalement avec un coussin d'allaitement (groupe 'Verticale') puis le groupe 2 avec l'installation en Flexion Diagonale Soutenue (groupe 'FDS'), observé consécutivement et apparié sur le groupe 1, en fonction du terme et du poids des enfants inclus. L'étude a porté sur le nouveau-né grand prématuré, sa mère et leur communication multimodale (modalités vocale, visuelle, tactile et sourire) sur cinq temps : à la naissance, au 1er peau-à-peau, 15 jours plus tard, à l'âge du terme corrigé, et à trois mois d'âge corrigé, soit sur une durée de six à sept mois par dyade. Résultats : dès le tout premier peau-à-peau, les mères installées en 'FDS', manifestent un maternage tactile spontané plus actif et varié, davantage affectif, et proposent d'emblée une enveloppe sonore plus dense et plus musicale. Les mères du groupe 'FDS' montrent un risque de dépression postpartum significativement plus bas après 15 jours de pratique peau-à-peau et à l'âge du terme corrigé, allongent naturellement le temps de séances et développent enfin une plus grande variabilité dans leur portage à bras. Installés en peau-à-peau durant l'hospitalisation, non seulement chacun des 2 partenaires manifestent plus de comportements multimodaux mais les comportements du nouveau-né grand prématuré apparaissent contingents (à 1 sec) à ceux de la mère en plus grande proportion. Au terme corrigé, les différences se résorbent en partie, mais on observe un meilleur investissement de l'état éveillé calme avec un engagement visuel des enfants davantage centré sur le visage de leur mère. Par ailleurs, à cet âge, les nouveau-nés grands prématurés du groupe 'FDS' présentent moins de déformations posturales et une meilleure organisation de la motricité spontanée. Conclusion : cette recherche de doctorat met en évidence que la pratique du soin peau-à-peau peut être améliorée avec l'installation en 'FDS', en soutenant physiquement le nouveau-né prématuré et psychiquement sa mère, et enfin en enrichissant la communication multimodale mère-enfant et en leur offrant l'opportunité précoce d'être plus sensibles l'un à l'autre comme socle de rencontre
Context: nowadays, skin-to-skin care is common practice in neonatal medicine services. It provides a unique relational opportunity that can be offered shortly after premature birth and it has already shown many benefits for the premature new-born and his/her parents. Like other care practices, skin-to-skin care can still be improved and adjusted to the high-technology environment of industrialized countries, in order to create an optimal sensorimotor and relational niche. Objective: the objective of the research-action of this doctoral thesis was precisely to test the benefit of a change of positioning during skin-to-skin care in NICU. Our hypothesis was that the innovative positioning in Supported Diagonal Flexion ('SDF') would allow improvements in the opportunity for individualized parent-new-born interactions, but also provide support to the construction of parenthood, plagued by premature birth, and improve postural and motor prevention in the premature new-born. Methods: we conducted a prospective monocentric interventional control-case study. Forty-two very premature infants, born between 27 and 32 weeks of gestation, and their mothers were included from may 2015 to july 2016. They were allocated to two groups: group 1 with skin-to-skin installation as it is commonly carried out in situ, which is 'Vertical' with a nursing pillow ('Vertical' group) and group 2 with Sustained Diagonal Flexion ('FDS' group), observed consecutively and matched with group 1 according to the term and weight of the children included. The study looked at the very premature infant, his/her mother et their multimodal communication (vocal, visual, tactile and smile) at five stages: at birth, during the first skin-to-skin, 15 days later, at term corrected age and at three months corrected age, thus on a six to seven months' time-span for each dyad. Results: from the very first skin-to-skin, mothers installed in 'FDS' displayed more affective, active and varied spontaneous tactile mothering, and immediately offer a more dense and musical sound cocoon. Mother in the 'FDS' group had a significantly lower risk of post-partum depression after 15 days of skin-to-skin practice and at term corrected age, they naturally lengthened the duration of skin-to-skin sessions and developed more variability when carrying their infant in their arms. When installed in 'FDS' during hospitalization, the two partners dispayed more multimodal behaviours and the infant's behaviours were contingent (1 s) to the mother's in greater proportion. At term corrected age, these differences partly reversed, but we observed a better investment of the calm awake state, with the child's visual engagement more focused on his/her mother's face. At term corrected age, premature infants in the 'FDS' group showed less postural deformations and a better organization in spontaneous motricity. Conclusion: this doctoral thesis demonstrates that skin-to-skin practice can be improved through the 'SDF' positionning, by physically supporting the new-born, psychologically supporting his/her mother, and finally allowing richer multi-modal mother-child communication by offering the early opportunity to be more sensitive to one another as a basis for the relationship

Increased workload on our healthcare system calls for more automation, this too in the pre-operative planning of total knee arthroplasty (TKA) surgery. This should keep in mind however that success in TKA is measured through having proper limb alignment. This thesis project implemented a virtual positioning assessment software that provides an initial position based on its bone and implant inputs with their specific landmarks. Positions can be furtherly adapted and evaluated based on flexion facets, obtaining decreased pre-operative workloads. The software was validated through an analysis comparison of the femur positioning of nine cases with the former used analysis tool of the university Hospital of Ghent. The newly implemented software was concluded to approximate the patients’ pre-operative alignment better for all translational and rotational parameters, except anteroposterior translation and internal/external rotation of the femur.

This thesis presents a proposed methodology for the field evaluation of the efficiency, energy, environmental, and safety impacts of traffic-flow improvement projects. The methodology utilizes Global Positioning System (GPS) second-by-second speed measurements using fairly inexpensive GPS units to quantify the impacts of traffic-flow improvement projects on the efficiency, energy, and safety of a transportation network. It should be noted that the proposed methodology is incapable of isolating the effects of induced demand and is not suitable for estimating long-term impacts of such projects that involve changes in land-use. Instead, the proposed methodology can quantify changes in traffic behavior and changes in travel demand. This thesis, also, investigates the ability of various data smoothing techniques to remove such erroneous data without significantly altering the underlying vehicle speed profile. Several smoothing techniques are then applied to the acceleration profile, including data trimming, Simple Exponential smoothing, Double Exponential smoothing, Epanechnikov Kernel smoothing, Robust Kernel smoothing, and Robust Simple Exponential Smoothing. The results of the analysis indicate that the application of Robust smoothing (Kernel of Exponential) to vehicle acceleration levels, combined with a technique to minimize the difference between the integral of the raw and smoothed acceleration profiles, removes invalid GPS data without significantly altering the underlying measured speed profile The methodology has been successfully applied to two case studies provided insights as to the potential benefits of coordinating traffic signals across jurisdictional boundaries. More importantly two case studies demonstrate the feasibility of using GPS second-by-second speed measurements for the evaluation of operational-level traffic flow improvement projects. To identify any statistically significant differences in traffic demand along two case study corridors before and after traffic signal condition, tube counts and turning counts were collected and analyzed using ANOVA technique. The ANOVA results of turning volume counts indicated that there is no statistically significant difference in turning volumes between the before and after conditions. Furthermore, the ANOVA results of tube counts also confirmed that there did not appear to be a statistically significant difference (5 percent level of significance) in the tube counts between the before and after conditions.

Questo elaborato è stato strutturato in 3 diversi capitoli, nel capitolo 1 sono presentate informazioni generali su: che cosa sia un sistema GPS, come funzioni, i suoi principali errori e alcune implementazioni. Il capitolo 2 riguarda i sistemi GPS indoor di nuova tecnologia e le loro applicazioni. Mentre il capitolo 3 racchiude una analisi di alcuni studi, che riguarda l'utilità della raccolta dati, tramite sistemi GPS nell'ambito sportivo. In particolare nella prima parte si studia la validità e l'affidabilità delle misure GPS considerando l'evoluzione delle unità GPS stesse con l'aumento di frequenza di campionamento. Una volta verificati questi parametri, sono stati presi in considerazione nella seconda parte la raccolta di alcuni studi, riguardanti il monitoraggio dell'attività fisica di individui comuni in relazione all'ambiente in cui si trovano. Verificandone la qualità dei dati tramite lo studio della quantità dei dati persi. Infine nell'ultima parte viene focalizzata la ricerca sulle diverse variabili misurabili con il GPS: distanza totale, distanza relativa, velocità e carico sul corpo degli atleti, e come esse cambiano in relazione ai ruoli, alla competitività e all'età. Quest'ultima analisi è sviluppata nel contesto di vari sport di squadra.

Tourism is one of Zambia’s undeveloped economic sectors, which if developed and marketed globally would provide employment, foreign exchange and international recognition. The purpose of this study was to find out how Zambia National Tourist Board could improve the awareness in Finland of Zambia's diverse tourism attractions and how Zambia is positioned in Finland as a tourist destination in Southern Africa. Primary data was collected by using long face to face interviews with members of the Association of Finnish Travel Agents, selected members from societies and clubs promoting adventure activities, staff at Zambia National Tourist Board and other tourism experts. Secondary data was derived from archival records. The data was analysed using inductive reasoning approach. The results of this study show that the image of Zambia in Finland is not strong and recognisable, there is a strong perception of poor safety for tourists, that Zambia is an expensive destination owing to the lack of direct flight connections, there is lack of promotional materials in local language, there is inadequate information on what Zambia as a tourist destination has to offer and that the positioning strategies adopted by Zambia National Tourist Board are ambiguous and are not structured. Consequently the recommendations are to set up a strategy to make available as much promotional materials. Furthermore, ZNTB must continue to position Zambia as an adventure tourist destination were one can enjoy exceptional wildlife and adventure. The Victoria Falls should be used as a unique feature around which an image can be developed.

I denna kandidatuppsats besvaras frågan om vilka designlösningar på förpackningen till en olivolja som i butikssammanhang positionerar sig som mer exklusiv och därmed bidrar till att målgruppen inhandlar produkten. För att ta reda på detta har observationer på sådana olivoljeflaskor gjorts i tre utvalda butiker. Utifrån dessa observationer har sedan en trendanalys gjorts. Med utgångspunkt ur trendanalysen har ett designarbete gjorts där fyra olika olivoljeförpackningar tagits fram baserade på element som används på en majoritet av dagens olivoljeförpackningar som positionerar sig som mer exklusiva. Förpackningarna är 3D-modeller modellerade i 3D Studio Max och etiketterna har skapats i Illustrator och Photoshop och har i den sistnämnda programvaran sammanfogats med förpackningarna. Med hjälp av bärbar eye-trackingutrustning fick fyra deltagare se de framtagna förpackningarna och med blicken svara på frågor angående dessa. Förpackningarna visades med hjälp av en projektor på en vägg, i naturlig storlek och uppradade på en simulerad butikshylla. Efter detta intervjuades deltagarna genom att använda kvalitativa frågor angående deras åsikter om olivoljeförpackningarna. Resultaten visar att varumärkesnamnets utformning är viktigt samt att en förpackning till en olivolja som positionerar sig som mer exklusiv bör vara gjord av glas, vara mjuk och följsam, samt innehålla ett mönster på etiketten. Form och mönster är de element som verkar vara de mest minnesvärda elementen och för att locka målgruppen är det viktigt med en förpackning som sticker ut på butikshyllan. En alltför innovativ form är inte att rekommendera medan en innovativ etikett kan vara fördelaktig. Tidigare erfarenheter har en betydelse vid val av förpackning och varumärkesnamn, produktbeskrivare och produktnamn bör tydligt uttryckas. Det är även fördelaktigt om designlösningen får konsumenten att vilja använda förpackningen som en del av köksinredningen. Färger, ovanliga för denna typ av produkt, kan skapa ett positivt ”hyllintryck” och färger som associeras till positivitet, värme, sol och energi kan i synnerhet locka konsumenter inom målgruppen. Symmetri i utformningen av etiketter för olivoljor som positionerar sig som mer exklusiva är fördelaktigt liksom användningen av en ljus nyans i etiketten i kontrast till ett mörkare textelement och/eller grafiskt element.
In this bachelor thesis the question regarding which design solutions, concerning the packaging to an up-market olive oil, contribute to the target group purchasing the product. To find out, observations on the up-market olive oil packaging of today was made in three selected stores. Based on the observations a trend analysis was made. With this analysis as a base, a design task, where four different olive oil packages were produced. These packages were based on elements frequently used on the present olive oil packaging. The packages are 3D-models made in 3D Studio Max and the labels were made in Illustrator and Photoshop. The labels were then merged with the packages using Photoshop. Using portable eye-tracking equipment, four participants were shown the four different olive oil packages, and got to answer questions concerning these packages, by using their eyes. The packages were shown through a projector, on a plain wall, in natural size and lined up on a simulated store shelf. Afterwards the participants answered qualitative questions regarding their opinions concerning olive oil packaging. The results show that the formation of the brand name is of importance and that a packaging for an up-market olive oil should be made out of glass, have a streamlined shape and a label that contains a pattern. The most memorable elements seem to be shape and pattern and in order to attract the target group, it is important to use a packaging design that stands out on the store shelf. An overly innovative shape is not to be recommended, but an innovative label can be beneficial. Prior experiences are of importance when choosing a packaging and brand name, product descriptor and product name should clearly be expressed. It is also beneficial if the design solution makes the consumer want to use the packaging as a part of the interior design in the kitchen. Colors unusual for this type of product can be used to create a positive ‘shelf impact’ and colors associated with positivity, warmth, sun and energy can especially tempt the consumers of the target group. Symmetry in the layout of the labels for up-market olive oil is beneficial as well as the use of a light color tone on the label in contrast to a darker text element and/or graphic element.

Visando usufruir do potencial dos sistemas de posicionamento global existentes, novos métodos de posicionamento têm surgido e outros vêm sendo aprimorados. Uma grande tendência nos últimos anos tem sido o uso de redes de estações GNSS de referência. Mas, tanto no uso de redes como nos demais métodos, um fator importante para melhorar a qualidade do posicionamento está relacionado com a modelagem atmosférica. Especial atenção deve ser dada aos erros que ocorrem devido à ionosfera, pois ela se tornou a principal fonte de erro no posicionamento GNSS, após desativação da técnica SA. Este erro é diretamente proporcional ao Conteúdo Total de Elétrons (TEC) e inversamente proporcional ao quadrado da frequência do sinal. O TEC e, consequentemente, o erro ionosférico variam no tempo e no espaço, e sofrem diversas influências, como: ciclo solar, época do ano, hora local, localização geográfica, atividade geomagnética, entre outros. Atualmente, o os erros proporcionados pela ionosfera podem ter seus efeitos minimizados a partir de arquivos IONEX ou por meio de modelagem ionosférica. Portanto, nesta pesquisa, foram utilizados dados das estações da RBMC em diferentes regiões do Brasil no período de baixa e alta densidade de elétrons do pico solar 24 para avaliar o desempenho dos mapas ionosféricos, no posicionamento baseado em redes, disponibilizados por diversos centros (CODE, ESA, JPL, UPC e IGS), bem como os fornecidos pelo projeto MIMOSA, e também os modelos de Grade (AGUIAR, 2010) e estimativa de TEC. Para tal fim, foi adotado um sistema computacional desenvolvido na FCT/UNESP, denominado VRS-Unesp, que emprega o conceito de Estação Virtual. De acordo com os resultados obtidos, nota-se que não há um único mapa fornecido pelos centros de análise do IGS que melhor se enquadra a realidade brasileira, além disso, o desempenho do mapa depende das condições ionosféricas e, principalmente, da localização da estação. Além disso, verificou-se que a acurácia obtida pelo IONEX do projeto MIMOSA, pelo modelo de grade e de Estimativa do TEC que utilizam dados regionais e possuem maior resolução espacial e temporal, foram os que apresentaram os melhores resultados. Por fim foi avaliada a correlação entre a acurácia do posicionamento por ponto e o índice de cintilação S4, já que a ionosfera pode não apenas degradar a acurácia do posicionamento GNSS como reduzir sua disponibilidade, pois existe uma alta dependência entre perdas do sinal e irregularidades ionosféricas. Como resultado, considerando a análise de espaço-frequência em relação ao tempo pelo método coerência wavelets para avaliação da correlação da série, nota-se uma correlação no périodo do equinócio superior a 70%.
In order to take advantage from global positioning systems, new positioning methods have emerged and others have been improved. An important tendency in recent years has been the use of GNSS reference stations networks. But, using networks or other positioning methods an important factor to improve the positioning quality is related to atmospheric modeling. Special attention should be given to errors that occur due to ionosphere, it became the largest error source in GNSS positioning after disabling SA technique. Ionosphere error depends on signal frequency and Total Electron Content (TEC) in the ionospheric layer. TEC and consequently the ionospheric error varies regularly in time and space and they are affected by different sources like: sunspot number (solar cycle), season, local time, geographic position, geomagnetic activity, and others. Currently, the errors provided by the ionosphere can be minimized using IONEX files or models. Therefore, in this research, the RBMC stations data were used in different regions of Brazil in the period of low and high electron density of the cycle solar 24 to evaluate the performance of the ionospheric maps, in network-based positioning, available from several centers, as CODE , ESA, JPL, UPC and IGS, as well as those provided by the MIMOSA project, and also the Grade Models (AGUIAR, 2010) and TEC Estimates. For this, a computer system developed in FCT / UNESP has been adopted, RSV-Unesp that uses the concept of Virtual Station. According to the results, we note that there is not single map of IGS analysis centers that best fits the Brazilian reality, moreover, the map performance depends on the ionospheric conditions and, primarily, the station location. Moreover, it was found that the accuracy obtained by IONEX the MIMOSA project, the Grade Model and TEC estimation using regional data and have higher spatial and temporal resolution, showed the best results. Finally we evaluated the correlation between the accuracy of point positioning and scintillation index S4, since the ionosphere can not only degrade the accuracy of GNSS positioning as well as reduce its availability, because there is a high dependency between signal loss and ionospheric irregularities. As result, considering the space-frequency analysis with respect to time by the wavelet coherence method for evaluation of the correlation of the series, there is a correlation in the period of higher equinox to 70%.

The European New Car Assessment Programme (Euro NCAP) performs several different tests to evaluate vehicles and rate their safety. Some of these tests are subsystem tests made to mimic different body parts of a pedestrian in an interaction with a vehicle. However, some criticism to the test method for the upper leg has been presented, stating that there is a discrepancy between this test method and a real-life interaction. Therefore, a modified test method for the upper leg has been proposed. The aim of this thesis was to evaluate the upper leg test method used today by Euro NCAP, and compare it with the proposed modified test method as well as to computer simulations with a Human Body Model (HBM). The evaluation was performed by comparing different parameters obtained in the two test methods. These have also been compared to computer simulations using a HBM in interaction with a passenger vehicle model. Prior to the evaluation of the test methods, the HBM was positioned into different stances to mimic postures in the human walking cycle. The vehicle model was positioned at four different heights, and three different impact points along the bonnet were used. The results showed that the different methods had their own advantages for some parameters. However, no general conclusion of which method showed the closest correlation to the HBM reference simulations could be determined.
European New Car Assessment Programme (Euro NCAP) utför flera olika tester för att utvärdera fordon och betygsätta deras säkerhet. Några av dessa tester sker med delsystem skapade för att efterlikna olika kroppsdelar hos en fotgängare i en kollision med ett fordon. Viss kritik har dock riktats mot testmetoden för lårben och höft, då studier visat att det finns en skillnad mellan testmetoden och en verklig kollision. En modifierad testmetod för lårbenet och höften har därför föreslagits. Syftet med detta examensarbete har varit att utvärdera testmetoden för lårben och höft, som idag används av Euro NCAP, och jämföra den med den föreslagna modifierade testmetoden men även datorsimuleringar med en humanmodell. Utvärderingen har genomförts genom att jämföra olika parametrar som erhållits från de två testmetoderna. Dessa parametrar har även jämförts med datorsimuleringar av fotgängarkollisioner med en humanmodell och en bilmodell. Humanmodellen positionerades i olika kroppsställningar innan utvärderingen av testmetoderna genomfördes. Detta för att efterlikna verkliga positioner i en mänsklig gångcykel. Bilmodellen positionerades vid fyra olika höjder och tre träffpunkter längs motorhuven användes. Resultaten visade att båda metoderna hade fördelar gentemot varandra för vissa parametrar. Ingen generell slutsats kunde dock dras om vilken metod som visade närmast korrelation till referenssimuleringarna med humanmodellen.

Syftet med denna uppsats är att studera hur svenska små- och medelstora tillverkningsföretag eventuellt påverkas i tider då den svenska valutakursen fluktuerar och förstärks kraftigt. Vidare har målet med uppsatsen varit att studera om, och i så fall hur dessa företags internationella konkurrenskraft och strategier påverkats som en effekt av den svenska valutakursens fluktuationer. Den teoretiska referensramen inkluderar huvudsakligen teorier som behandlar företags strategi och internationella konkurrenskraft. Dessa teorier har vi använt med målet att studera och förklara hur företag hanterar den svenska valutakursens fluktuationer för att bibehålla sin internationella konkurrenskraft. Vidare så har vi försökt finna samband mellan hur dessa förändrats under tid inom företaget och om utvecklingen kan förklaras med utvecklingen av den svenska valutakursen som påverkande faktor. Uppsatsens metodologiska referensram grundar sig i en kvalitativ forskningsmetod samt med en deduktiv ansats, för att på det mest lämpliga vis besvara uppsatsen huvudproblem. För att få djupare inblick i ämnet har vi använt oss utav en fallstudie som forskningsstrategi där vi undersökt 5 stycken fallföretag i Kalmar län. Uppsatsens slutsats påvisar att de studerade fallföretagen uppvisar en samlad bild där det hanterar den svenska valutakursens förändringar på ett förhållandevis bra sätt. Fallföretagen hanterar den svenska valutakursens fluktuationer genom en väl definierade positionering som är en stark bidragande faktor till internationell konkurrenskraft.

In navigation from one place to another, spatial knowledge helps us establish a destination and route while travelling. Therefore, sufficient spatial knowledge is a vital element in successful navigation. To build adequate spatial knowledge, various forms of spatial tools have been introduced to deliver spatial information without direct experience (maps, descriptions, pictures, etc.). An innovation developed in the 1970s and available on many handheld platforms from the early 2000s is the Global Position System (GPS) and related map and text-based navigation support systems. Contemporary technical achievements, such as GPS, have made navigation more effective, efficient, and comfortable in most outdoor environments. Because GPS delivers such accurate information, human navigation can be supported without specific spatial knowledge. Unfortunately, there is no universal and accurate navigation system for indoor environments. Since smartphones have become increasingly popular, we can more frequently and easily access various positioning services that appear to work both indoors and outdoors. The expansion of positioning services and related navigation technology have changed the nature of navigation. For example, routes to destination are progressively determined by a “system,” not the individual. Unfortunately we only have a partial and nascent notion of how such an intervention affects spatial behaviour. The practical purpose of this research is to develop a trustworthy positioning system that functions in indoor environments and identify those aspects those should be considered before deploying Indoor Positioning System (IPS), all towards the goal of maintaining affordable positioning accuracy, quality, and consistency. In the same way that GPS provides worry free directions and navigation support, an IPS would extend such opportunities to many of our built environments. Unfortunately, just as we know little about how GPS, or any real time navigation system, affects human navigation, there is little evidence suggesting how such a system (indoors or outdoors) changes how we find our way. For this reason, in addition to specifying an indoor position system, this research examines the difference in human’s spatial behaviour based on the availability of a navigation system and evaluates the impact of varying the levels of availability of such tools (not available, partially available, or full availability). This research relies on outdoor GPS, but when such systems are available indoors and meet the accuracy and reliability or GPS, the results will be generalizable to such situations.

In wireless sensor networks, indoor localization is becoming an important application. To achieve the desired positioning accuracy, two major design issues should be considered: (1) the localization algorithm and (2) the distance measurements. This thesis focuses on changing communication angles and altitudes in order to change behavior of ultrasonic transducers and explore the effects on positioning accuracy. The proposed ultrasonic indoor positioning system consists of ultrasonic sensors with known position information, embedded system modules with TOA distance measurements, and the Bayesian localization algorithm. Experimental results show that the performance difference between the system with the Height-Change and the system with Height/Theta-Change is about 10% improvement in estimation accuracy.

GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. These biases influence the accuracy in precise GNSS positioning if not handled properly. This thesis is based on two papers, where one is a review paper published in GPS Solutions, and the other is a research paper currently in review (resubmitted after minor revision) for Journal of Geodetic Science. The first paper compiles current results and gives an overview of those situations where biases are of the greatest importance for precise positioning. The second paper investigates the satellite dependency in two cases of relative phase biases. In the first paper, a review is given on how hardware biases influence precise GNSS positioning in various situations. These can roughly be divided into five cases: positioning not employing the ionosphere free combination to which the satellite clock corrections are aligned, GNSS based ionospheric modeling, determination of the phase ambiguity as an integer in PPP, and positioning with GLONASS. In the second paper, the satellite dependency for two cases of relative phase biases are investigated: relative between-receiver biases in single differenced phase observations from two receivers, relative between-signals biases in observation differences between two signals recorded by the same receiver and associated with the same carrier frequency. In both these cases a satellite dependency was discovered. The first case showed a difference of 0.8 mm between the greatest and smallest values, while the corresponding difference in the second case was 3.5 mm. It was also discovered that the biases in the first case varied periodically over time, and with a period of one sidereal day. The exact cause for these variations could however not be determined in the experiment, even though multipath could be excluded as their source.
Hårdvaru-relaterade biases kan beskrivas som små systematiska fel som uppkommer i kod- och bärvågs-observationer vid GNSS-mätning. Dessa uppstår i hårdvaran hos både satellit och mottagare, och inverkar på positionsosäkerheten vid noggrann GNSS-positionering om de inte hanteras. Denna avhandling är baserad på två artiklar, varav den ena är publicerad i GPS Solutions, och den andra är under granskning (återinskickad efter en mindre omarbetning) för Journal of Geodetic Science. Den första artikeln ger en överblick över hårdvaru-relaterade biases och de situationer då de är som mest betydelsefulla för noggrann positionering. Den andra artikeln undersöker om det eventuellt existerar ett satellit-beroende hos två fall av hårdvaru-relaterade biases för bärvågsobservationer. I den första artikeln tas fem fall upp som är särskilt betydelsefulla gällande hårdvaru-relaterade biases. Dessa är: positionering som inte använder den jonosfärsfria linjärkombination av GNSS-observationer som mottagna satellit-klock-korrektioner är anpassade för, GNSS-baserad jonosfärsmodellering, heltalsbestämning av periodobekanta vid PPP-positionering, positionering med flera GNSS-system, och positionering med Glonass specifikt. I den andra artikeln undersöks satellit-beroendet för två fall: relativa bärvågsobservationer mellan två mottagare, relative bärvågsobservationer mellan två signaler observerade av samma mottagare och med samma bärvågsfrekvens. I båda fallen upptäcktes ett satellitberoende. Variationerna i första fallet visade en differens mellan största och minsta värdet på ungefär 0.8 mm, medan motsvarande värde i andra fallet var ungefär 3.5 mm. Det visade sig också att hårdvaru-relaterade biases i det första fallet varierade periodiskt över tiden, med en period av ett sideriskt dygn. Den exakta orsaken för dessa variationerna kunde ej bestämmas, även om flervägsstörningar kunde uteslutas som källa.

Most of the current indoor positioning technology is the active systems which need to bring portable identification locators all the time. It will cause trouble in life. However, passive position systems have often been interfaced by furniture and space layout. The purpose of this research is to improve the above-mentioned disadvantages of indoor positioning technology. Deciding to position the signal caused by footsteps .The signal induced by footsteps can be divided into vibration and sound, after the primary stage to study, we must judge sound is a better signal for analysis because processing easy and high equipment availability. Therefore, research priorities will focus on sound localization. Unlike most traditional microphone array algorithm positioned by the angle of wave source geometry, in which derived scanning optimization by scanning the graph of the error function and find the minimum region, cleverly avoiding falling into local minimum. The advantages of this method allow for the distributed sensor and thus increase the volatility of indoor furniture placement. This paper also discusses the layout of the sensors position influence the accuracy of positioning. Finally in the experiment to find out the reasons will affect the positioning error and provide improved methods.

This study intends to examine the relationship between a happy positioning, utilitarian products and willingness to pay. After reviewing existent literature, it is hypothesised that by associating utilitarian products to a happy positioning, willingness to pay will be positively impacted. In order to test this hypothesis, research was conducted following an experimental design involving one pre-test and one main study. The main study consisted of a between subjects experiment with two conditions: happiness vs performance positionings. Against the hypothesis, results suggest that willingness to pay for utilitarian products does not differ significantly depending on the condition individuals were allocated to.

With the progress of communication, manufacturing technology, convenience of transportation and the appearance of emerging market, international enterprise had begun their globalization to magnify the management category, which induced global competition and outsourcing activities, and therefore resulted in the inconsistency of product between "country of origin" and "country of manufacture". To overcome the variety of plenty brands, the marketing strategy which enterprise adopted must focus on creating a clear and vivid "brand position" to strengthen their brand value for building strong brand. This study had used "Fuzzy AHP" method to determine the importance among country of origin, country of manufacture and brand equity, by designing and distributing the questionnaires to 34 experts in academy and business, including college professors and enterprise executive managers. According to data analysis, there were some main ideas concluded: Country of origin is the most important dimension on brand positioning, and brand equity lay beneath in second place, and country of manufacture is less effective on brand positioning. In addition, representative product, brand loyalty and reputation were the most important criterion among each of above formations. Finally, underlying these findings, some suggestions for strategy were interpreted, and the managerial implications of the framework were proposed for academy and business, and some research limitations were mentioned.

This study presents solutions for GPS orbit computation from broadcast, precise ephemerides, and the precise broadcast orbit correction using least squares support vector machine. Moreover, it analyzes impacts of sampling time and fitting method and the choice of ephemerides on precision of orbit, also evaluates the accuracy of ground point positioning after fitting. According to the experimental results, the fitting errors of satellite’s 3D coordinate components are still in the range of precise ephemerides while using LSSVM fitting with training set of about 75% sampling rate in 2 hours. The single point positioning precision of fitting ephemerides are 0.3~0.7m higher, and the positioning satellite coordinates are about 1.5m closer than that obtained from original broadcast ephemerides computing. Results show that the proposed approach by using fitting of ephemerides to reduce computation process has been adopted, it solves the problem in the past that the precise ephemerides couldn’t directly be used in ground single point positioning due to the lack of satellite velocity measurement, and also prove that the studied approach is capable of providing an effective and universal precise fitting orbit, upgrading the accuracy of ground point positioning.

Individuals are importance resources for organizations. Optimal resource allocation and synergy are essential paths for improving the competitiveness of industries. Human resources are undoubtedly the most significant factor that influences the advantages of an enterprise. Under the trend of financial tsunami, the allocation of innovative human resource is the most unique strength of competitiveness, of which the differentiation effects are difficult to duplicate. In the era of intense competition and high concept, the work of employees is confronted simultaneously by financial tsunami and reduced orders. If innovative effects of human resources are to obtain direct efficacy, enterprises should create their competitive strength by utilizing professionals’ knowledge to manage companies. However, the formation of innovative strategies requires more aggressive policies that reform the established norms of manpower positioning. New strategies should be proposed to provide employees or enterprises with new values that guide them through financial difficulties. This study discussed the influence of manpower positioning and innovative strategies on the plastic industries under financial tsunami, as well as the relationship between manpower positioning and innovative strategies. In-depth expert interviews and surveys were conducted to collect data regarding recruitment, selection, payment, benefit, educational training, and career planning. Using stratified sampling method, this study distributed 600 surveys to plastic business owners, and obtained 513 valid samples. Analytical methods included ANOVA and IPA. Based on the analysis, this study proposed innovative manpower positioning strategies to ensure the appropriate employee numbers, employee quality and supply as well as to satiate enterprises’ needs to sustain the industry.

Technique for Impact Localization on Carbon Fiber Laminate Sheets: il problema affrontato è stato quello della localizzazione di un impatto a bassa energia (simulati con sfere in caduta libera) su strutture planari in materiale polimerico rinforzato con fibra di carbonio (CFRP) per mezzo della formula di triangolazione di Tobias sviluppando un nuovo algoritmo “di verosimiglianza” per l’estrazione del tempo di arrivo differenziale (DToA) da una coppia di sensori piezoelettrici flessibili incollati alla superficie del materiale. In particolare, è stata fatta la caratterizzazione della lastra in CFRP in termini di diagramma delle velocità di propagazione delle onde di Lamb. L’algoritmo ha reso indipendente la valutazione del DToA dal tipo di trasduttore utilizzato, ha migliorato la stima l’accuratezza delle coordinate di impatto. I parametri da inserire nel sistema di elaborazione sono minimi e sono stati migliorati i tempi di elaborazione. Sono state sviluppate nuove geometrie per i sensori in PVDF. Infine, è stato popolato un data base con i segnali acquisiti ed estratti dati statistici con i quali è stato possibile valutare l’algoritmo e confrontarlo con il metodo classico a soglia fissa per lastre in CFRP. Analysis of the errors in the estimation of impact positions in plate-like structure through the triangulation formula: l’attività di ricerca si è svolta concentrandosi sullo studio di una sperimentazione che diminuisse i parametri di incertezza. È stata condotta quindi un’analisi degli errori nella stima della posizione di impatto su alluminio attraverso la formula di triangolazione. Inizialmente, al fine di ridurre l’incertezza sulla generazione degli impatti con sfere in caduta libera, è stato realizzato un sistema meccanico, completo di elettronica di pilotaggio, per la generazione di impatti controllati e ripetibili. Il lavoro si è concentrato su una semplice procedura di laboratorio basata su un set-up con una coppia di sensori posizionati simmetricamente rispetto al punto di impatto, per stimare l'incertezza del DToA e la velocità di propagazione. Successivamente dallo studio del modello matematico di triangolazione sono stati individuati ed indagati, in modo simulato, i due fattori che ne influiscono sulla stima: il tempo differenziale di arrivo (DToA) ad ogni coppia di sensori dell’array e l’incertezza sulla stima della velocità di gruppo delle onde guidate di Lamb. Le prove sperimentali per la misura della velocità delle onde di Lamb e per la stima del DToA, sono state fatte su di una lastra di alluminio di spessore 1.4 mm con sensori piezoelettrici commerciali. Poiché l'errore per la stima DToA dipende anche dal tipo di elaborazione del segnale adottato, tra i molti metodi riportati in letteratura per la stima del DToA, abbiamo analizzato e confrontato tre metodi: l'attraversamento di una soglia predeterminata, il metodo di correlazione e l’algoritmo di “verosimiglianza” sviluppato in [A1]. Per il rilevamento dell'incertezza della velocità di propagazione, sono state calcolate le curve di dispersione della piastra di alluminio ed i risultati sono stati poi confrontati con le misurazioni sperimentali. Inoltre, un'analisi teorica ha mostrato come gli errori che influenzano il DToA e la velocità di propagazione agiscano sulla stima del punto di impatto nella formula di triangolazione. L'analisi dell'errore di posizionamento, nell’ottica di un utilizzo di configurazione multisensoriale, è considerata utile per la progettazione di un sistema di monitoraggio strutturale (SHM).

Abstract: This research report analyses the extent to which Britain maintained a neo-colonial, Eurocentric mentality towards the arts of Africa over the course of the decade 1995 to 2005. Two exhibitions that focused on the arts of Africa were mounted in Britain during this period. Both of these exhibitions, used as case studies in this research report, clearly demonstrated that entrenched stereotypes persist regarding Africa’s artistic output. The africa95 and Africa 05 programmes highlighted the fact that African artists are valued in Western centres primarily for their ‘difference’, continually being marginalised through omnibus narratives that single out African artists as producing the work of the Other. ‘Traditional’ African art is equated with ‘authentic’ African art and the work of contemporary African artists is either compared with the ‘traditional’, or negated for being too influenced by Western aesthetics. Discourses around identity and representation of African artists in the West have been impacted by numerous factors such as the growth and increased profile of the African diaspora. While entrenched mindsets in the West towards African art are beginning to shift, ultimately the identity of contemporary African artists is framed within very narrow parameters that have been created by Western art centres and imposed upon African artists. In this context, the insular British cultural establishment has proven particularly resistant to change. The centre/periphery paradigm serves as a protective measure for British cultural identity. However, even as subtle shifts away from this perspective begin and the initial stages of an acceptance of contemporary African art is revealed, it is nonetheless a very limited advancement that still revolves around a small number of British institutions and curators who set the parameters of the discourse. In summary, this analysis of the decade under review reveals that very little has changed regarding the positioning of African art in Britain.

Security is a function of the trust that is associated with the active variables in a system. Thus, the human factor being the most critical element in security systems, the security perimeter could be defined in relation to the human trust level. Trust level could be measured via positive identification of the person/device on the other side of the interaction medium, using various authentication schemes; location-based being one of the latest. As for the location-based services, the identity of a customer remains hazy as long as his location is unknown; he virtually remains a ghost in the air, with implications on trust. This paper reviews the various location-based authentication techniques with a focus on the role that GPS could play in optimising this authentication approach. It advocates the urgent need to make all transmission devices GPS-compliant as a way forward, despite the privacy issues that might arise.

changing customer needs towards natural cosmetics. The adoption of fair trade (FT) could offer an opportunity for cosmetics producers and this is an area of research that is limited; so far, studies mainly surround the willingness to pay (WTP) on an ethical premium for food products, such as coffee and chocolate. As consumers could react differently to this “ethical improvement” for different product types, analyzing consumer preferences for FT in the context of the cosmetics industry is of high interest. This thesis seeks to understand to what extent and under what conditions could the adoption of FT certification be beneficial for cosmetics producers in Germany. With data obtained through a questionnaire with an experimental design component, the research evaluates how the FT certification paired with brand positioning and product categories would influence the consumers’ WTP for natural cosmetics in Germany. The results suggest that FT certification of natural cosmetics leads to a high WTP an ethical premium among German female consumers. In addition, it was found that it is particularly favorable to introduce FT at products with smaller price ranges, as the WTP in percent is significantly higher for lower price ranges. Finally, it is found that the WTP for FT certified natural cosmetics varies across different product categories but does not vary significantly with brand positioning.
A indústria de cosméticos Alemã está a diversificar a orientação do seu comércio para ir ao encontro da mudança de necessidades dos consumidores para cosméticos naturais. A adoção de um comércio justo pode apresentar uma nova oportunidade aos produtores de cosméticos. No entanto, até hoje as pesquisas realizadas focam principalmente a predisposição para pagar um preço eticamente mais elevado para produtos alimentares como o café e o chocolate. Dado que consumidores de categorias diferentes podem reagir de forma diferente face a essa “melhoria ética”, analisar as preferências dos consumidores para um comércio justo no contexto da indústria de cosméticos é de grande interesse. Esta tese pretende compreender em que medida e em que condições a adoção de um comércio justo poderia ser benéfico para os produtores de cosméticos na Alemanha. Com resultados obtidos por meio de um questionário com um componente de design experimental, esta dissertação avalia em que medida a certificação de comércio justo, considerando também o posicionamento das marcas e as categorias de produto, poderia influenciar a predisposição dos consumidores para pagar por produtos cosméticos naturais na Alemanha. Os resultados sugerem que a certificação de comércio justo de produtos cosméticos naturais leva a uma predisposição para pagar um preço eticamente mais elevado entre consumidoras femininas alemãs. Adicionalmente, foi possível compreender que é particularmente favorável introduzir o comércio justo em produtos com pequenos intervalos de preços, dado que a predisposição para pagar em percentagem é significativamente maior para intervalos de preços menores. Por último, analisando o impacto das categorias de produto e o posicionamento das marcas é possível compreender que a predisposição para pagar por produtos cosméticos com certificado de comércio justo não varia independentemente de ter um preço premium.

Preterm infants actively and continuously interact with their surrounding environment through the autonomous system and their behavioral state. When the premature infants can not cope with the environmental stimuli, they will develop stressful behaviors and increase energy consumption. If they can cope with the environmental stimuli, they will show regulatory behaviors that save energy and promote growth. What are the influences of the current neonatal intensive care and positioning to the behaviors of preterm infants? The purposes of this study are to explore: (1) the types of neonatal caregiving for preterm infants, and the occurrences of stressful and regulatory behaviors, (2) the effects of the infant characteristics on their behaviors, (3) the effects of different types of neonatal caregiving and positioning on their behaviors. The study was an exploratory design to examine the effects of neonatal caregiving and positioning on preterm infants’ behavioral responses. Data were collected at neonatal intensive care unit of a medical center in Northern Taiwan. Eleven preterm infants (PCA 27.7 – 35.0 weeks) who met the study criteria were recruited into the study using convenience sampling. The method of data collection used structured observation. Preterm infant behaviors were measured by using preterm infant behavior coding scheme. Each infant was continuously observed 24 hours for 3 days. We used descriptive statistics to analyze the infant characteristics, types of caregiving procedure and frequencies of the behavior. Generalized estimated equation was used to analyze the effects of the infant characteristics, types of caregiving procedures, and positioning on their behavioral responses. The results showed that: (1) The frequencies of the actions of the preterm infants in one day were maximum in moving hand to mouth, face or head, while grasping the hands were the least; (2) The infant characteristics affect the development of stressful and regulatory behaviors; (3) For the effects of caregiving, the types of invasive treatment and routine care significantly increase stressful behavior, while social interaction will significantly reduce the limb and trunk extension, and significantly increase their crying behaviors; (4) Routine care and social interaction significantly reduced the frequencies of hands to mouth, face and head, but significantly increased grasp and self-sucking or chewing;(5) For special caregiving activities, nonnutritive sucking significantly reduces stressful behaviors, feeding and bathing both significantly increased the stressful behaviors; (6) In special care activities, nonnutritive sucking significantly reduced the regulatory behaviors of self-sucking or chewing, bathing increased significantly regulatory behavior of grasping; (7) Supine position significantly increased the stressful behaviors, while prone position significantly reduced the stressful behaviors; (8) Prone position significantly reduced regulatory behaviors of self-sucking or chewing and grasping. In general, the results showed that even routine care still interrupted the preterm infant’s sleep. The prone position was more likely to decrease stressful behaviors than the supine position. Further analysis was required explore the related factors that may affect the preterm infant’s sleep, and behaviors. The study findings guide caregivers to develop some supportive interventions to promote the preterm infant’s behavioral organization and growth.

Tese de doutoramento em Engenharia Eletrotécnica e de Computadores, na especialidade de Automação e Robótica, apresentada ao Departamento de Engenharia Eletrotécnica e de Computadores da Faculdade de Ciências e Tecnologia da Universidade de Coimbra
O congestionamento do tráfego no centro das cidades e impacto ambiental associado estão entre os principais desafios colocados hoje em dia aos investigadores na área da mobilidade. Este trabalho tem como objectivo contribuir para a melhoria da mobilidade urbana, em termos do aumento da capacidade das infraestruturas rodoviárias e da redução das emissões dos veículos. O presente trabalho está incluído no domínio dos "Sistemas de Transportes Inteligentes", nomeadamente na simulação de tráfego de veículos autónomos e análise das emissões de CO2 ao um nível microscópico. O trabalho incidirá sobre o desenvolvimento de metodologias para a gestão de tráfego em intersecções, auxiliadas por um sistema de localização multi-sensorial. Um ambiente de simulação integrado é analisado no contexto do desenvolvimento de algoritmos "Inteligentes de Gestão de Tráfego" (Intelligent Traffic Management-ITM) aplicados em intersecções, nomeadamente em rotundas e e cruzamentos. Os resultados deste trabalho, disponibilizam dados relevantes sobre consumo de combustível e sobre as emissões de gases de efeito estufa CO2, habilitando a avaliação dos algoritmos inteligentes de gestão de tráfego em intersecções para veículos autónomos, relativamente às técnicas tradicionais de regulação de trânsito em rotundas e cruzamentos. A estimação precisa da localização de um veículo e o controlo da mesma, é de extrema importância para o desenvolvimento e operação de algoritmos ITM, portanto, sendo o seu desenvolvimento também realizado e analisado. O trabalho desenvolvido encontra-se dividido em três grandes temas: ambiente de simulação integrado, algoritmos ITM e estimação da localização de veículos. No âmbito deste trabalho foi desenvolvido como um ambiente de simulação denominado ISR-TRAFSIM (disponível em: http://www2.isr.uc.pt/~conde/isr-trafsim/). Este simulador é baseado em Matlab, o seu código fonte encontra-se disponível, e tem o potencial para ser usado em estudos diversos da área de transportes inteligentes, nomeadamente: controlo automático de tráfego rodoviário, análise de emissões de veículos automóveis, controlo de seguimento de trajectória de veículos autónomos e de fusão de sensorial para efeitos de localização precisa e percepção de situações anómalas ou perigosas. Vários algoritmos ITM foram desenvolvidos, visando minimizar o número de acidentes, o congestionamento do tráfego e consequentemente reduzir os custos ambientais do tráfego rodoviário. Os algoritmos ITM desenvolvidos, são baseados em metodologias de reserva espaço-temporal. Estas metodologias asseguram que os veículos se deslocam através do cruzamento sem colidir com outros veículos, ao mesmo tempo que conseguem reduzir o tempo de espera no cruzamento assim como os seus impactos ambientais. Este trabalho demonstra que existe o potencial para a redução de emissões e aumento do fluxo de tráfego através da utilização de algoritmos ITM. Para implementar a gestão de tráfego em cenários de condução cooperativa, a estimativa da localização e velocidade dos veículos deve ser precisa e robusta. Em sistemas localização de veículos baseados apenas em receptores GNSS, a precisão resultante pode ser afectada por erros de vários metros. Neste trabalho avaliou-se a potencial melhoria na localização de veículos equipados câmaras de detecção da linha de marcação lateral da estrada, em cenários cooperativos para reduzir os erros de posição absoluta de veículos através da partilha em rede de informação em tempo real. As técnicas utilizadas nos algoritmos de localização são baseadas em métodos intervalares, usados para determinar conjuntos de pertença com erro delimitado, estas metodologias foram usadas para determinar localização baseada em GNSS, com garantida da solução se encontrar dentro de um conjunto com um determinado risco. Para resolver o problema das "pseudoranges" com multi-percurso do tipo NLOS e propagação do erro quando se utiliza algoritmos colaborativos, desenvolveram-se algoritmos robustos, baseados na detecção de medidas aberrantes de satélites, e no relaxamento das restrições usadas na computação do conjunto de pertença.
Traffic congestion in city centers and its associated environment impact are among the major challenges pose to mobility researcher nowadays. This thesis aims to contribute for urban mobility improvement, in terms of road capacity and vehicle emissions. The current work is included in the Intelligent Transportation Systems research area, namely traffic simulation of autonomous vehicles and CO2 emissions assessment at a microscopic level. The thesis will focus on the development of methodologies for the traffic management in intersections aided by precise multi-sensor positioning. This research explore a simulation framework for the development of Intelligent Traffic Management (ITM) algorithms in road intersections, namely roundabout and crossroads. The research work provide an assessment of novel intersection traffic management algorithms for automated vehicles on fuel consumption and greenhouse gas emissions of CO2 relative to traditional traffic signal and roundabout intersection control. An accurate vehicle's pose estimation and control is of extreme importance for the inner working of the ITM algorithms, therefore its development is also performed and analyzed. The research work is divided in three major topics: simulation framework, ITM algorithms and vehicle pose estimation. In the framework of this research the ISR-TRAFSIM was developed as the simulation environment (available at: http://www2.isr.uc.pt/~conde/isr-trafsim/). It is an open-source Matlab-based simulator and it has the potential for being used in diverse studies such has: automatic traffic control, vehicle emissions analysis, vehicle path-following control and sensor fusion for vehicle awareness. Several ITM algorithms were developed, aiming to minimize accidents, traffic congestion and consequently the environmental costs of road traffic. The developed intelligent traffic management ITM algorithms, which are based on a spatiotemporal reservation scheme, ensure that vehicles proceed through the intersection without colliding with other vehicles while at the same time reducing the intersection delay and environmental impacts. This research demonstrates that there is the potential of emission reduction and optimized traffic flow through the use of these ITM algorithms. To implement the traffic management in cooperative driving scenarios, the estimated pose and speed of vehicles must be both accurate and robust. When vehicles localization systems involve standalone GNSS receivers, the resulting accuracy can be affected by satellite-specific errors of several meters. This work studied how road-features like lane marking detected by on-board cameras can be exploited to reduce absolute position errors of cooperative vehicles sharing information in real-time in a network. The algorithms considered in this work are based on a error bounded set membership strategy, these methodologies were used to compute GNSS guaranteed risk integrity zone. A robust set-inversion based algorithm was also developed, to solve the problem of NLOS multipath and its error propagation when using collaborative algorithms.

Na era moderna, a par de variadas mudanças na vida quotidiana, as novas relações de consumo proporcionaram o aparecimento de um novo consumidor que se tornou elemento central e essencial dessa relação. Tornou-se fundamental entender o seu comportamento e, nomeadamente, a sua percepção relativamente às marcas. O valor de uma marca é uma questão central para o marketing bem como para a própria gestão de uma marca. Este valor pode associar-se à notoriedade da marca, aos atributos e ao seu posicionamento. O posicionamento é uma componente crucial da estratégia de marketing, permitindo a uma marca ter uma vantagem competitiva que forneça ao consumidor um motivo forte para que este, em última instância, a compre. Compreender o posicionamento percebido pelo consumidor de uma marca é um passo indispensável ao planeamento da estratégia de marketing. O presente trabalho tem como principal objectivo investigar hipotéticas alterações na percepção dos consumidores acerca da posição das marcas, principalmente devido à entrada de um novo produto no mercado de uma marca consolidada. A aplicação fez-se ao mercado dos desodorizantes. A utilização da técnica de MDS permitiu a elaboração de um mapa perceptual antes e depois da introdução do novo produto. Através da realização de inquéritos, procedeu-se a uma análise de dissemelhanças – os inquiridos, consumidores de desodorizantes, agruparam as marcas consoante a sua percepção de proximidade, e avaliaram-nas recorrendo a um conjunto de atributos considerados relevantes para a categoria. Em resultado do trabalho realizado, constataram-se algumas mudanças, ainda que ligeiras, no posicionamento das marcas.
In the modern ages, amongst other changes on the daily life, the new consumer relationships also drove the appearance of a new consumer which became a key and essential element of this relationship. It’s indispensable to understand the consumer behavior, namely its perception in relation to trade-marks/brand. The value of a trade-mark it’s a key element not only for the Marketing but also for the management of the trade-mark itself. This value can be linked to the trade-mark notoriety, attributes and to its positioning/ranking (in the market). The trade-mark positioning plays a key role on the marketing strategy, allowing a trademark to have a competitive advantage that supplies the consumer with a strong motive/incentive so that, ultimately the consumer purchase it. Understand the positioning perceived by the consumer of a trade-mark it’s a indispensable step planning the marketing strategy. The main goal of this dissertation is to investigate hypothetical changes/shifts, on the consumer perception in relation to trade-mark position, mainly driven by the appearance in the market of a new product from a consolidated trade-mark. The study was applied to the deodorant market. The MDS was applied and allowed one the elaboration of a perceptual map, before and after the introduction of the new product. From inquiries to deodorant consumers, a dissimilarity analyses was performed – the deodorant consumers inquired, grouped the trade-marks according to the consumer proximity perception, and evaluate the trade-marks using attributes considered relevant for the category. From the results obtained by this investigation it was noticed some slightly changes on the trade-marks positioning.
