Banh, Mai Thi Quynh, and n/a. "Quantification, characterisation and impact evaluation of mobile IPv6 hand off times." Swinburne University of Technology, 2005. http://adt.lib.swin.edu.au./public/adt-VSWT20070608.094836.
Full textAbstract:
There is a growing range of IP-based data and voice applications using mobile devices (e.g. 3rd ,
4th generation mobile phones and PDAs) and new access technologies (e.g. Bluetooth, 802.11,
GPRS, ADSL). This growth is driving a desire to support mobility at the IP level � in other
words, allowing an IP host to keep on communicating with other hosts while roaming between
different IP subnetworks.
Mobile IPv6 allows hosts to move their physical and topological attachment points around
an IPv6 network while retaining connectivity through a single, well-known Home Address.
Although Mobile IPv6 has been the subject of simulation studies, the real-world dynamic
behavior of Mobile IPv6 is only gradually being experimentally characterised and analysed.
This thesis reviews the use of Mobile IPv6 to support mobility between independent
802.11b-attached IPv6 subnets, and experimentally measures and critically evaluates how long
an end to end IP path is disrupted when a Mobile IPv6 node shifts from one subnetwork to
another (handoff time). The thesis describes the development of an experimental testbed
suitable for gathering real-world Mobile IPv6 handoff data using publicly available, standards compliant
implementations of Mobile IPv6. (An open-source Mobile IPv6 stack (the KAME
release under FreeBSD) was deployed).
The component of handoff time due to 802.11b link layer handoff is measured separately to
assess its impact on the overall Mobile IPv6 handoff time. Using Mobile IPv6 handoff results,
the likely performance impact of Mobile IPv6 handoff on a common webcam application and a
bulk TCP data transfer is also evaluated. The impact of handoff on these applications clearly
shows that a default Mobile IPv6 environment would be highly disruptive to real-time and
interactive applications during handoff events, even if the underlying link-layer handoff was
instantaneous.

Full textAbstract:
Particulate matter is increasingly linked to health effects not only for what was previously thought to be just a respiratory problem, but also for the cardiovascular system. Literature not only supports that high particulate matter over long periods of time is correlated to morbidity and mortality due to both cardiovascular and respiratory means, but that high levels of particulate matter, even in short bursts of high concentrations, may be the triggering mechanism for the onset of such problems. Due to automobiles being a prime source of particulate matter, roadway concentrations are often higher than those measured at off-road measurement sites run by various parts of the United States Government. Furthermore, the government run sites are averaged over timescales at a minimum of an hour and at a maximum of a running three-day twenty-four hour length. These are both so long that mesoscale information about the particulate matter, such as short duration high intensity bursts, would be completely removed from the dataset. This study utilizes a real-time portable instrumentation package, which can effectively measure particulate matter concentrations on the roadways of metro Atlanta. Measurements are taken both inside the cabin of a vehicle, which does have an in-cabin filtration system, and on a bicycle ridden along the streets without any form of filtration. These instruments, specifically calibrated handheld particle counters, did indeed find some spikes of particulates above the government s one-hour averages inside the cabin of a vehicle. Arguably more importantly, while riding a bicycle these handheld particle counters also found spikes of particulates approaching six times the amount monitored by the government sites, and several roadway averages that were higher than the off-road averages for the same time.

Les conséquences des chocs économiques négatifs sur les ménages ont été documentés extensivement, mais on en sait beaucoup moins sur la manière dont ces chocs sont transmis aux individus à travers la médiation du ménage. Le ménage contribue-il à modérer l'effet des chocs négatifs ? Dans quelle mesure le choc économique pèse-t-il dans la négociation familiale ? À partir de données sur la crise économique argentine de 2001, je montre d'abord que les femmes en couple ont une plus grande probabilité de devenir actives si leur mari a fait l'expérience d'un choc de revenu. Ensuite, je montre que le cycle économique importe dans les décisions d'investissement en capital humain. Sur le long terme, les profils de salaire et d'employabilité des hommes argentins sont affectés de manière persistante par les conditions économiques initiales au moment de l'obtention du diplôme. Enfin, je considère la dimension “man-cession” de la crise économique de 2009 en Espagne et montre que la part des ressources du ménage reçues par les femmes pour leur consommation privée augmente avec la diminution de l'écart des taux de chômage hommes-femmes, confortant l'hypothèse que les chocs négatifs modifient le pouvoir de négociation des individus au sein du ménageThe consequences of adverse aggregate shocks on households have been repeatedly documented, but far less has been said on the way they are passed over to individuals through the mediation of the household. Does the household contribute in mitigating the effects? Or does the economic shock rather invite itself at the family negociating table? Using the Argentine 2001 economic crisis as a natural experiment, I first show that married women are more likely to enter the labor market if their husband experienced a loss in income, giving credit to the insurance mechanism. Then, I show that the business cycle matters for investments in education, and that long run labor outcomes of Argentine men are persistently affected by the initial conditions upon graduation. Finally, I consider the “Mancession” dimension of the Great Recession in Spain and demonstrate that the resource share accruing to wives for own consumption increases together with the decreasing unemployment gap, which comes in support to the bargaining hypothesis

Full textAbstract:
This thesis focuses on bare hand gesture recognition by proposing a new architecture to solve the problem of real-time vision-based hand detection, tracking, and gesture recognition for interaction with an application via hand gestures. The first stage of our system allows detecting and tracking a bare hand in a cluttered background using face subtraction, skin detection and contour comparison. The second stage allows recognizing hand gestures using bag-of-features and multi-class Support Vector Machine (SVM) algorithms. Finally, a grammar has been developed to generate gesture commands for application control.
Our hand gesture recognition system consists of two steps: offline training and online testing. In the training stage, after extracting the keypoints for every training image using the Scale Invariance Feature Transform (SIFT), a vector quantization technique will map keypoints from every training image into a unified dimensional histogram vector (bag-of-words) after K-means clustering. This histogram is treated as an input vector for a multi-class SVM to build the classifier. In the testing stage, for every frame captured from a webcam, the hand is detected using my algorithm. Then, the keypoints are extracted for every small image that contains the detected hand posture and fed into the cluster model to map them into a bag-of-words vector, which is fed into the multi-class SVM classifier to recognize the hand gesture.
Another hand gesture recognition system was proposed using Principle Components Analysis (PCA). The most eigenvectors and weights of training images are determined. In the testing stage, the hand posture is detected for every frame using my algorithm. Then, the small image that contains the detected hand is projected onto the most eigenvectors of training images to form its test weights. Finally, the minimum Euclidean distance is determined among the test weights and the training weights of each training image to recognize the hand gesture.
Two application of gesture-based interaction with a 3D gaming virtual environment were implemented. The exertion videogame makes use of a stationary bicycle as one of the main inputs for game playing. The user can control and direct left-right movement and shooting actions in the game by a set of hand gesture commands, while in the second game, the user can control and direct a helicopter over the city by a set of hand gesture commands.

Full textAbstract:
Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew. Studies show that prolonged hands-off time has a negative impact on survival after a sudden cardiac arrest. Purpose The purpose with this study was to look into if the hands-off time could decrease with use of manual mode on the defibrillator by the ambulance crew. The crew had to analyze, make a decision to chock or not, charge the defibrillator and give the chock if appropriate. Furthermore, the crews’ knowledge in analyzing heart rhythms that can be defibrillate was investigated. Method A quasi-experimental method was used. 38 participants, all ambulance crew, were included in the study. The participants were randomized into two groups. One group performed CPR with an AED, the second group used the manual mode on the defibrillator. The study data were processed in SPSS. Results The time preceding the first defibrillation was significant shorter in the group using manual mode. There was no difference in total hands-off time between the two groups. All heart rhythms were interpreted right and all defibrillation were done correctly. Conclusions Time from establish cardiac arrest to first defibrillation was significant shorter in manual mode. Furthermore, all heart rhythms were interpreted right and all defibrillation were done correctly. Time from first defibrillation to start of chest compressions was equal in the two groups. There were no significant differences in hands-off time between the two groups.

Full textAbstract:
In this observational study the researcher examined the Academic Engagement of deaf and hard of hearing (D/HH) students in a co-enrollment setting. Academic Engagement refers to attention, class participation, and time-on-task. Co-Enrollment is a model of group inclusion that provides D/HH students with access to a D/HH peer group as well as access to the general education curriculum. D/HH students typically lag behind their hearing peers in achievement, due in part to difficulties with accessing the general education curriculum both in special schools for the Deaf or self-contained classrooms, as well as in traditional inclusive settings. One way to know if a student has actually had access to, rather than mere exposure to the curriculum is to determine if he has attended to the instruction and participated in the instructional activities. Co-enrollment programming holds promise for addressing the problems with access that D/HH students typically experience in other educational placements; therefore the researcher hypothesized that in this unique setting D/HH students would demonstrate levels of Academic Engagement equal to their hearing peers. The researcher further hypothesized that there would be a relationship between Academic Engagement and the classroom environment, and that this relationship would be similar for D/HH and hearing students. Using a correlational research design, these hypotheses were tested by conducting repeated observations with use of the Mainstream Version of the Code for Instructional Structure and Student Academic Response (MS-CISSAR) for measuring Academic Engagement. Results indicated that D/HH students in a co-enrollment setting were as Academically Engaged as their hearing peers; however they were less engaged in active forms of Academic Engagement (i.e., Academic Responding) than their hearing peers. Associations were found between aspects of Classroom Ecology, such as the size of Instructional Grouping, and the degree of Academic Engagement for both D/HH and hearing students. The associations between Academic Engagement and Classroom Ecology were similar for D/HH and hearing students; however some differences were found as well. The implications of these results are discussed and suggestions are made for future research.

Full textAbstract:
The global economic crisis that began in 2007 affected the lives of many people in the UK. Most existing research into the effects of ‘the Great Recession’ on well-being takes an economic or subjective approach to assessing the impacts of hard times. This thesis takes an alternative perspective: the Capabilities Approach (CA) is used to assess the effects of economic crisis on people’s freedom to lead flourishing lives. The study develops a theoretical framework that combines the CA with concepts from Philosophy and Social Psychology - the theories of practical reason and personal values. These concepts are then operationalised using data from the European Social Survey and quantitative methods, including latent variable techniques and structural equation models. The study reveals that economic crisis had a two-fold effect on well-being, resulting in (1) reduced opportunities to achieve valuable outcomes and (2) diminished expectations, aspirations and goals. These effects were concentrated among socio-economically vulnerable groups, including those on low incomes and the long-term sick and disabled: the findings show that economic crisis compounded existing socio-economic inequalities. The research makes three main contributions. First, it demonstrates theoretically and empirically that subjective well-being is not a reliable indicator for evaluating the effects of hard times on well-being; nor is it, more generally, a suitable guide for public policy. Second, it demonstrates a new methodological approach to identifying latent ‘value orientations’ within Schwartz’s framework of personal values. Third, in combining the CA with theories of practical reason and personal values, this research offers a new approach to conceptualising and measuring the agency aspect of capability.

Full textAbstract:
Developing countries and the poor within them (i.e., the other) receive scant attention in management and organization studies (MOS). The field, thus, suffers from both ethnocentric and class biases. This research effort seeks to reduce these biases, particularly in the conversation on power taking place between MOS' critical management studies and interorganizational collaboration research streams.Articulating a case study of the Sialkot soccer ball child labour project in Pakistan (1995-2003), the thesis explores the communication constraints that are faced by weak actors in interorganizational domains (a social problem and a set of organizations having a stake or interest in that problem) located in the developing world. Relying on both written documents (private and public) and field interviews, especially with women soccer ball stitchers at the village level, a typology of communication constraints is developed. These constraints are examined from the perspectives of those at the bottom of the international supply chain and the injuries these groups suffer from them are documented in the thesis. It is found that the ability of weak actors to use communication to influence a domain is highly contingent on how space and time are configured in a domain. Domains have temporal rhythms and spatial configurations. The thesis identifies two types of temporal rhythms (technocratic and subsistence clocks) and a spatial configuration (imperial space) that severely militate against weak actors exercising agency in a domain through communication. Strategies (e.g., emergent collective struggle) that can prevent weak actors from becoming subalternalized (voiceless) in a domain are also discussed. The case study permits an investigation of contemporary transnational activism that often sires interorganizational collaboration projects in developing countries. The thesis identifies two types of transnational activism (thick and thin), delineates the various elements constituting them, and shows how thin activism can lead to interorganizational projects hurting weak and powerless groups that are intended to be assisted.

Full textAbstract:
AimsParticipant drop out is a major barrier to high-quality patient-reported outcome (PRO) data analysis in cancer research as patients with worsening health are more likely to dropout. To test the hypothesis that ovarian cancer patients with worse PROs would drop out earlier, we examined how patients differed by time of dropout on health-related quality of life (HRQOL), anxiety, depression, optimism and insomnia. MethodsThis analysis included 619 participants, stratified by time of dropout, from the Australian Ovarian Cancer Study - Quality of Life substudy, in which participants completed PRO questionnaires at three-monthly intervals for 21 months. Trends in PROs over time were examined. Pearson correlations examined the relationship between time of dropout and baseline PROs. Multiple linear regression models including age, disease stage and time since diagnosis examined relationships between baseline and final PRO scores, and final PRO scores and dropout group. ResultsParticipants who dropped out earlier had significantly worse baseline HRQOL (p<0.0001) and higher depression (p<0.0001). For all five PROs, final scores were significantly associated with baseline scores (p<0.0001). Time of dropout was significantly associated with final HRQOL (p=0.003), anxiety (p=0.05), depression (p=0.02) and optimism (p=0.02) scores. Depression, HRQOL and anxiety worsened at a faster rate overtime in dropouts than study completers. ConclusionsPoorer HRQOL and higher depression at baseline, and final HRQOL, anxiety, depression and optimism scores were predictive of time of dropout. These results highlight the importance of collecting auxiliary data to inform careful and considered handling of missing PRO data during analysis, interpretation and reporting.

Full textAbstract:
An industry is constantly affected by its environment and the changes that occur within it. These environmental forces are the drivers of the industry’s evolution and throughout its life an industry undergoes irreversible transformations, which creates an industry life cycle. The competitive pressure on firms has increased the importance of developing competitive strategies throughout the industry’s life. This becomes especially important when the industry reaches the decline stage. There are different strategies that are suggested for firms to undertake in a declining industry. However, these strategies do not consider small and medium-sized enterprises, thus they might not be the most suitable for these firms to undertake. In addition, international activities have not been seen as a way to increase performance in a declining industry. The purpose of this study is therefore to fill this gap by investigating how small and medium-sized enterprises seek to increase their performance in a declining industry. To fulfil this purpose, we have conducted a qualitative case study of four SMEs currently operating in a declining industry. The empirical data was collected through interviews at each case company.The theoretical framework includes the theoretical concept of the industry life cycle, strategies specific for declining industries, theories regarding how firm chooses to compete, and different theories regarding international activities. The chapter ends with a theoretical synthesis that is developed from the theories presented earlier in the chapter. The empirical chapter presents the findings from the interviews with the case companies.In the analysis, the theoretical framework is connected to the empirical data, and is the basis for our conclusions. After conducting this study we can conclude that small and medium-sized enterprises seek to increase their performance by undertaking a niche strategy as their end-game strategy, compete with a differentiations strategy, and by a large scope of international markets, which enables them to shift their market focus from unbeneficial markets to more beneficial markets.

Full textAbstract:
Computational Fluid Dynamics Coupled to Discrete Element Method (CFD-DEM) is widely used in simulating a large variety of particulate flow system. This Eulerian-Lagrangian technique tracks all the particles included in the system by the application of point mass models in their equation of motion. CFD-DEM is a more accurate (and more expensive) technique compared to an Eulerian-Eulerian representation. Compared to Particle Resolved Simulations (PRS), CFD-DEM is less expensive since it does not require resolving the flow around each particles and thus can be applied to larger scale systems. Nevertheless, simulating industrial and natural scale systems is a challenge for this numerical technique. This is because the cost of CFD-DEM is proportional to the number of particles in the system under consideration. Thus, massively parallel codes are used to tackle these problems with the help of supercomputers.
In this thesis, the CFD-DEM capability in the in-house code Generalized Incompressible Direct and Large Eddy Simulation of Turbulence (GenIDLEST) is used to investigate large scale dense particulate flow systems. Central to the contributions made by this work are developments to reduce the computational cost of CFD-DEM. This includes the development and validation of reduced order history force model for use in large scale systems and validation of the representative particle model, which lumps multiple particles into one, thus reducing the number of particles that need to be tracked in the system. Numerical difficulties in the form of long integration times and instabilities encountered in fully coupling the fluid and particle phases in highly energetic systems are alleviated by proposing a partial coupling scheme which maintains the accuracy of full-coupling to a large extent but at a reduced computational cost. The proposed partial-coupling is found to have a better convergence behavior compared to the full coupling in large systems and can be used in cases where full coupling is not feasible or impractical to use. Alternative modeling approaches for the tangential treatment of the soft-sphere impact model to avoid storing individual impact deformation are proposed and tested. A time advancement technique is developed and proposed for use in dense particulate systems with a hard-sphere impact model. The new advancement technique allows for the use of larger time steps which can speed-up the time to solution by as much as an order of magnitude.PHD

Full textAbstract:
The present thesis follows an intensive care unit during four year of hard work and demanding organisational changes (1998-2001). The changes were mainly initiated by diminishing resources and a legislative claim to pay regard to the quality aspect of health care service. The process of implementing a quality system was the main focus for the thesis. Triangulation was used aiming at explore the process from different views. Two interviews studies were conducted one with the staff and another with the leadership. Both interviews were analysed thematically combined with a phenomenographic technique (e.g. using the how, and what aspect). A longitudinal quasi experimental time-series study was also accomplished. The correlation between staff variables and workload were measured once a year. The result show a 20 % increase in workload per staff and year. The staff judged the organisational climate for innovativeness stable over the period. Sick leave increased, and more so, than the general trend in the society. In spite of this increase the prevalence of stress related symptoms was the same. Two different systems emerged, a complex adaptive system and a mechanical system. The two systems exist and functions intertwined. Because of the construction of the patient register it is possible to see that the situation around a patients being admitted ≥ 5 days functions according to the complex systems character while the situation around the acute patients functions according to a mechanical system. Sick leave correlated with number of patient admitted ≥ 5 days (P=,000). It seemed the problem found had its root in the unawareness of the existing of a complex system. The result has implications for a need of increased awareness about how to manage the situation when the ICU is functioning according to the complex adaptive system.

Full textAbstract:
The worlds of Dickens's novels and of Darwin's science reveal striking similarity in spite of their involvement in different areas. The similarity comes from the fact that they shared the ethos of Victorian society: laissez-faire capitalism. In The Origin of Species, which was published on 1859, Charles Darwin theorizes that nature has evolved through the rules of natural selection, survival of the fittest, and the struggle for existence. Although his conclusion comes from the scientific evidence that was acquired from his five-year voyage, it is clear that Dawinian nature is reflected in cruel Victorian capitalism. Three novels of Charles Dickens which were published around 1859, Bleak House, Hard Times, and Our Mutual Friend, share Darwinian aspects in their fictional worlds. In Bleak House, the central image, the Court of Chancery as the background of the novel, resembles Darwinian nature which is anti-Platonic in essence. The characters in Hard Times are divided into two groups: the winners and the losers in the arena of survival. The winners survive in Coketown, and the losers disappear from the city. The rules controlling the fates of Coketown people are the same as the rules of Darwinian nature. Our Mutual Friend can be interpreted as a matter of money. In the novel, everything is connected with money, and the relationship among people is predation to get money. Money is the central metaphor of the novel and around the money, the characters kill and are killed like the nature of Darwin in which animals kill each other. When a dominant ideology of a particular period permeates ingredients of the society, nobody can escape the controlling power of the ideology. Darwin and Dickens, although they worked in different areas, give evidence that their works are products of the ethos of Victorian England.

Full textAbstract:
La réduction de toute temporalité préalable à la conscience immanente du temps est le point de départ de la phénoménologie du temps. La question à laquelle il s’agit de répondre est de savoir (1) s’il est possible d’accomplir la réduction phénoménologique de toute temporalité préexistante, et (2) par ailleurs, quelles sont les conséquences à tirer de la possibilité ou de l’impossibilité de cette réduction pour l’expérience du temps et pour la constitution du temps objectif. Dans notre recherche nous avons thématisé la question du statut phénoménologie du temps du monde en tant que problème limite de la phénoménologie en nous appuyant, d’une part, sur les manuscrits de Husserl afin d’argumenter en faveur de la possibilité de la réduction phénoménologique et, d’autre part, sur la phénoménologie du temps de Merleau-Ponty et Blumenberg qui problématisent la possibilité de l’accomplissement de la réduction phénoménologique du temps dans leur approche critique à la phénoménologie transcendantale. Tandis que Husserl met entre parenthèses le temps du monde et réduit le temps donné à l'expérience subjective du temps, Merleau-Ponty et Blumenberg insistent quant à eux sur la pré-donation d'un temps général ainsi que sur sa manifestation comme une perturbation dans la vie du sujet. Le passé naturel du corps (tel qu’évoqué par Merleau-Ponty) et la facticité du temps du monde (telle qu’évoquée par Blumenberg) sont les aspects indéniables de l'expérience du temps qui restent négligés dans l’approche de la phénoménologie du temps de Husserl. L’apparition du temps n'est pas l'identification continue et homogène du flux de la conscience absolue avec elle-même mais un mouvement discontinuThe reduction of any pre-given form of temporality to the immanent time-consciousness is the starting point of the phenomenology of time. The questions to be answered are (1) whether it is possible to accomplish this phenomenological reduction, and (2) what are the consequences of the possibility or the impossibility of this reduction for the experience of time and for the phenomenological constitution of objective time. In our research we have thematized the phenomenological status of the world-time as a limit problem of phenomenology by relying on Husserl manuscripts in order to argue in favor of the possibility of the phenomenological reduction, and on the phenomenology of time of Merleau-Ponty and Blumenberg who problematize the possibility of the accomplishment of the phenomenological reduction of time in their critical approach to the transcendental phenomenology. While Husserl brackets the world-time and reduces the given time to the subjective experience of time, Merleau-Ponty and Blumenberg insist on the pre-donation of a general time as well as on its manifestation as a perturbation in the life of the subject. The natural past of the body (Merleau-Ponty) and the facticity of world-time (Blumenberg) are the undeniable aspects of the time-experience, which remain neglected in Husserl’s approach to the phenomenology of time. The time-appearance is not the continuous and homogeneous identification of the flow of absolute consciousness with itself, but a discontinuous movement

This thesis investigates how understandings of history in diverse texts of the Graeco-Roman period illuminate Lukan eschatology. Two strands of Lukan scholarship have contributed to an enduring tendency to underestimate the centrality of eschatology to Luke/Acts. Hans Conzelmann's thesis, that Luke focused on history rather than eschatology as a response to the parousia's delay, has dominated Lukan scholarship since the mid-twentieth century, with concomitant assumptions about Luke's politics and understanding of suffering. Recent Lukan scholarship has centred instead on genre and rhetoric, examining Luke/Acts predominantly in relation to ancient texts deemed the same genre while overlooking themes (including those of an eschatological character) that these texts do not share. This thesis offers a fresh approach. It illuminates the inherent connections between Luke's understanding of history and its end, and demonstrates significant ways in which Luke's eschatological consciousness shapes key themes of his account. By extending comparisons to a wider range of texts, this study overcomes two clear methodological shortfalls in current research: limiting comparisons of key themes to texts of similar genre, and separating non-Jewish from Jewish texts. Having established the need for a new examination of Luke's eschatology in Chapter 1, in Chapter 2 I set out the study's method of comparing diverse texts on themes that cut across genres. Chapters 3 to 6 then consider each key text and Luke/Acts in relation to a different aspect of their writers' conceptions of history: the direction and shape of history; determinism and divine guidance; human culpability and freedom; and the present and the end of history. The analysis shows that in every aspect of history examined, Luke/Acts shares significant features of the texts with which, because they do not share its genre, it is not normally compared. Setting Luke/Acts in conversation with a broader range of texts highlights Luke's periodised, teleological view of history and provides a nuanced picture of Luke's understanding of divine and human agency, all of which is affected in fundamental ways by his portrayal of the present time already within the final period of history. As a result, this study not only clarifies Lukan eschatology, but reaffirms the importance of eschatology for Lukan politics and theodicy.

Les aquifères fracturés sont un enjeu majeur de l'hydrogéologie actuelle. Ils constituent une ressource essentielle pour de nombreuses populations. Le massif de l'Ursuya (France, 64), en est une illustration. Constitué de formations métamorphiques fracturées, il est intensément exploité pour l'alimentation en eau potable. Une approche multidisciplinaire a permis la compréhension du fonctionnement de ce système. Les résultats obtenus constituent une avancée dans la connaissance des aquifères discontinus et offrent des pistes pour une gestion raisonnée de cette ressource.Le signal d'entrée est caractérisé dans sa composante quantitative et qualitative. Le suivi des paramètres climatiques permet d'estimer la lame d'eau participant à la recharge de l'aquifère. La caractérisation isotopique de l'eau précipitée met ensuite en évidence une origine majoritairement atlantique des masses d'air, responsables des précipitations sur le nord-ouest du Pays Basque. Des circulations atmosphériques sur la péninsule Ibérique, l'Europe du Nord et la région méditerranéenne sont cependant responsables de certains événements pluvieux. La composition chimique de l'eau de pluie, résultant de ces origines, est caractérisée par une faible acidité et par des concentrations en éléments anthropiques parfois élevées.L'hydrochimie des eaux souterraines est étudiée conjointement avec des données de temps de séjour acquises par l'interprétation des concentrations en 3H, CFC et SF6. Les caractéristiques physico-chimiques, les temps de séjours mesurés (moins de 10 ans à plus de 50 ans) et les phénomènes de mélanges associés permettent de proposer un modèle conceptuel des écoulements souterrains. Celui-ci met en exergue le rôle prépondérant du profil d'altération développé dans les milieux cristallins (de la surface vers la profondeur : altérites, roche fissurée et roche saine), du point de vue de la minéralisation de l'eau comme de celui des modalités d'écoulement.Une approche quantitative est finalement proposée. Du point de vue hydrodynamique, l'hétérogénéité spatiale est importante (10-4 m s-1 < K < 10-8 m s-1). Les altérites offrent une capacité de stockage et de régulation de la recharge. Un modèle numérique synthétise et valide ces résultats. Les simulations montrent de fortes interactions entre les réseaux d'écoulements superficiel et souterrain et de faibles impacts de l'exploitation actuelle sur les flux d'eau souterraine. Les évolutions climatiques ne modifieront pas significativement les écoulements durant les prochaines décennies. Une diminution des débits des sources et des cours d'eau est toutefois probable. Ce modèle numérique et l'ensemble des résultats obtenus serviront de base pour une gestion raisonnée de la ressource en eau de l'aquifère de l'Ursuya.

There has existed for many years a memory enhancement technique ("memory pegs") that although having dramatic demonstrable success in some individual cases has not been generally applied in education. The emergence of constructivist epistemology has emphasised the notion that learning occurs as a result of connecting new material with previously learnt concepts. There is, therefore, the implication that effective learning requires some previous knowledge upon which to attach new concepts - and thus realisation of the importance of learning with respect to acquiring factual information as a prerequisite to learning new processes and/or skills. This issue has focussed my attention on the need to ensure that the more physiological skills of accessing 'memory', both for learning and recall, are optimised for maximum learning. Further, there are some indications that the physiological skills of memory access (storage and retrieval) may respond favourably to training and 'exercise'. This study was designed to find out whether or not a repeated 'exercise' using a simple memory enhancement technique would lead to a determinable and statistically significant increase in overall performance in a range of cognitive skills (as indicated by science and mathematics examination results), whether learning such a technique would affect a student's attitudes towards science, whether there was a relationship between the amount of time spent practicing the technique and the degree of effect, and whether the memory technique did actually improve the ability to recall lists of objects.

Multi functional health monitoring wearable devices are quite prominent these days. Usually these devices are battery-operated and consequently are limited by their battery life (from few hours to a few weeks depending on the application). Of late, it was realized that these devices, which are currently being operated at fixed voltage and frequency, are capable of operating at multiple voltages and frequencies. By switching these voltages and frequencies to lower values based upon power requirements, these devices can achieve tremendous benefits in the form of energy savings. Dynamic Voltage and Frequency Scaling (DVFS) techniques have proven to be handy in this situation for an efficient trade-off between energy and timely behavior. Within imec, wearable devices make use of the indigenously developed MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). This system is optimized for efficient and accurate collection, processing, and transfer of data from multiple (health) sensors. MUSEIC v2 has limited means in controlling the voltage and frequency dynamically. In this thesis we explore how traditional DVFS techniques can be applied to the MUSEIC v2. Experiments were conducted to find out the optimum power modes to efficiently operate and also to scale up-down the supply voltage and frequency. Considering the overhead caused when switching voltage and frequency, transition analysis was also done. Real-time and non real-time benchmarks were implemented based on these techniques and their performance results were obtained and analyzed. In this process, several state of the art scheduling algorithms and scaling techniques were reviewed in identifying a suitable technique. Using our proposed scaling technique implementation, we have achieved 86.95% power reduction in average, in contrast to the conventional way of the MUSEIC v2 chip’s processor operating at a fixed voltage and frequency. Techniques that include light sleep and deep sleep mode were also studied and implemented, which tested the system’s capability in accommodating Dynamic Power Management (DPM) techniques that can achieve greater benefits. A novel approach for implementing the deep sleep mechanism was also proposed and found that it can obtain up to 71.54% power savings, when compared to a traditional way of executing deep sleep mode.Nuförtiden så har multifunktionella bärbara hälsoenheter fått en betydande roll. Dessa enheter drivs vanligtvis av batterier och är därför begränsade av batteritiden (från ett par timmar till ett par veckor beroende på tillämpningen). På senaste tiden har det framkommit att dessa enheter som används vid en fast spänning och frekvens kan användas vid flera spänningar och frekvenser. Genom att byta till lägre spänning och frekvens på grund av effektbehov så kan enheterna få enorma fördelar när det kommer till energibesparing. Dynamisk skalning av spänning och frekvens-tekniker (såkallad Dynamic Voltage and Frequency Scaling, DVFS) har visat sig vara användbara i detta sammanhang för en effektiv avvägning mellan energi och beteende. Hos Imec så använder sig bärbara enheter av den internt utvecklade MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). Systemet är optimerat för effektiv och korrekt insamling, bearbetning och överföring av data från flera (hälso) sensorer. MUSEIC v2 har begränsad möjlighet att styra spänningen och frekvensen dynamiskt. I detta examensarbete undersöker vi hur traditionella DVFS-tekniker kan appliceras på MUSEIC v2. Experiment utfördes för att ta reda på de optimala effektlägena och för att effektivt kunna styra och även skala upp matningsspänningen och frekvensen. Eftersom att ”overhead” skapades vid växling av spänning och frekvens gjordes också en övergångsanalys. Realtidsoch icke-realtidskalkyler genomfördes baserat på dessa tekniker och resultaten sammanställdes och analyserades. I denna process granskades flera toppmoderna schemaläggningsalgoritmer och skalningstekniker för att hitta en lämplig teknik. Genom att använda vår föreslagna skalningsteknikimplementering har vi uppnått 86,95% effektreduktion i jämförelse med det konventionella sättet att MUSEIC v2-chipets processor arbetar med en fast spänning och frekvens. Tekniker som inkluderar lätt sömn och djupt sömnläge studerades och implementerades, vilket testade systemets förmåga att tillgodose DPM-tekniker (Dynamic Power Management) som kan uppnå ännu större fördelar. En ny metod för att genomföra den djupa sömnmekanismen föreslogs också och enligt erhållna resultat så kan den ge upp till 71,54% lägre energiförbrukning jämfört med det traditionella sättet att implementera djupt sömnläge.

Dissertação de Mestrado Conjunto Europeu em Tribologia de Superficies e Interfaces apresentada à Faculdade de Ciências e TecnologiaRecent developments such as turbocharging and downsizing in the automotive industry to enhance engine efficiency and reduce emissions are giving rise to the higher operation temperatures and loading densities in the internal combustion engines. Increased temperature stability (up to 500 °C) will be required for coatings of future’s engines compared to ones of present day. Hard tetrahedral DLC coatings (ta-C coatings) are very attractive to be used for automotive industry as they exhibit very low coefficient of friction and perform very well under mixed and boundary lubrication.This research project was carried out in the framework of the European TANDEM project which aims at developing a new generation of ta-C coatings. It is a follow up of the work previously carried out at CEMMPRE where substrate bias was optimized (-80 V) at 124 µs of oscillation pulse-off time. In this work, DLC coatings were deposited by deep oscillations magnetron sputtering (DOMS), a variant of high power magnetron sputtering (HiPIMS). The main objective is to study influence of oscillation pulse-off time (toff) in two series of depositions (at 0.4 Pa and 0.8 Pa) on the structural, mechanical, and tribological properties of the DLC films deposited by DOMS with substrate biasing. SEM, AFM, XPS analysis (only for 2 films), hardness, stress, and pin-on-disc measurements were carried out for studying DLC films. Regarding the DLC films deposited at 0.4 Pa, the hardness of the films shows significant changes with toff, most likely due to corresponding changes in the sp3/sp2 fraction of the films. However, the specific wear rate of the films remains very similar excepting for the film deposited at the highest toff (124 µs) which has a slightly denser microstructure. Overall, it can be concluded that decreasing toff does result in improved tribological properties, but better mechanical properties (i.e hardness) can be obtained. At a deposition pressure of 0.8 Pa, decreasing toff from 124 to 84 or even 64 µs results in both a lower friction coefficient and significantly lower wear rates without any appreciable loss of hardness. In fact, the specific wear rate of the film deposited at toff = 84 µs is not only the lowest specific wear rate measures in this work but it is also significantly lower than the specific wear rates measures in previous works about the deposition of DLC films by DOMS.
Em desenvolvimentos recentes, como turbocompressão e diminuição da cilindrada na indústria automotiva, o aumento da eficiência do motor e a redução das emissões estão gerando temperaturas mais altas de operação e elevadas densidades de carga nos motores de combustão interna. A estabilidade de temperatura aumentada (até 500 ° C) será necessária para revestimentos de motores futuros em comparação aos atuais. Os revestimentos DLC tetraédricos duros (revestimentos ta-C) são muito atraentes para serem usados na indústria automotiva, pois exibem um coeficiente de atrito muito baixo e funcionam muito bem sob lubrificação mista e de limite.Este projeto de pesquisa foi realizado no âmbito do projeto europeu TANDEM, que visa o desenvolvimento de uma nova geração de revestimentos de ta-C. Trata-se de um acompanhamento do trabalho realizado anteriormente no CEMMPRE, onde a polarização do substrato foi otimizado (-80 V) a 124 µs de tempo de pulso de oscilação. Neste trabalho, os revestimentos DLC foram depositados através de oscilações profundas de pulverização magnetron (DOMS), uma variante da técnica pulverização magnetron de alta potência (HiPIMS). O principal objetivo é estudar a influência do tempo de pulso de oscilação (toff) em duas séries de deposições (a 0,4 Pa e 0,8 Pa) nas propriedades estruturais, mecânicas e tribológicas dos filmes de DLC depositados pela DOMS com polarização de substratos. Foram realizadas análises de SEM, AFM, análise XPS (somente para 2 filmes), dureza, tensão e pino-sobre-disco para o estudo de filmes de DLC.Em relação aos filmes de DLC depositados a 0,4 Pa, a dureza dos filmes mostra variações significativas com o toff, provavelmente devido a mudanças correspondentes na fração sp3 / sp2 dos filmes. No entanto, a taxa de desgaste específica dos filmes permanece muito semelhante, com exceção do filme depositado no mais alto volume (124 µs), que possui uma microestrutura ligeiramente mais densa. No geral, pode concluir-se que a diminuição de toff resulta em melhores propriedades tribológicas, mas podem ser obtidas melhores propriedades mecânicas (isto é, dureza). A uma pressão de deposição de 0,8 Pa, a diminuição do toff de 124 para 84 ou mesmo 64 µs resulta em um coeficiente de atrito menor e taxas de desgaste significativamente reduzidas sem qualquer perda significativa de dureza. De fato, a taxa de desgaste específica do filme depositado em toff = 84 µs não é apenas a menor taxa de desgaste específico neste trabalho, mas também é significativamente menor que as medidas específicas de desgaste em trabalhos anteriores sobre a deposição de filmes de DLC.

This thesis considers how the Black dancing body constitutes both Black history and dance history by reading the body in Pearl Primus' Hard time blues, The Negro speaks of rivers and Strange fruit as physical auto/biography, or what I shall herein refer to as auto/body/graphy. The Black dancing body, because it is a repository of the Black experience, actively engages in the act of self-naming, self-shaping, and self-recognition. As such, it may be considered an auto/body/graphy that is situated in Black history, an instrument through which histories of origin and migration, struggle against oppression and colonialization, and the forging of identities and self-definition are inscribed and communicated. This thesis examines Primus' early choreographies as a discourse through which to consider the impact of Black cultural consciousness and the emergence of a Black aesthetic and Black corpo-reality in dance and theatre on the development of American modern dance before mid-century, and upon later choreographers who followed Primus.text

Full textAbstract:
American jurisprudence currently applies two incompatible validity standards to determine which laws are enforceable. The natural law tradition evaluates validity by an uncertain standard of divine law, and its methodology relies on contradictory views of human reason. Legal positivism, on the other hand, relies on a methodology that commits the analytic fallacy, separates law from its application, and produces an incomplete model of law.
These incompatible standards have created a schism in American jurisprudence that impairs the delivery of justice. This dissertation therefore formulates a new standard for legal validity. This new standard rejects the uncertainties and inconsistencies inherent in natural law theory. It also rejects the narrow linguistic methodology of legal positivism.
In their stead, this dissertation adopts a pragmatic methodology that develops a standard for legal validity based on actual legal experience. This approach focuses on the operations of law and its effects upon ongoing human activities, and it evaluates legal principles by applying the experimental method to the social consequences they produce. Because legal history provides a long record of past experimentation with legal principles, legal history is an essential feature of this method.
This new validity standard contains three principles. The principle of reason requires legal systems to respect every subject as a rational creature with a free will. The principle of reason also requires procedural due process to protect against the punishment of the innocent and the tyranny of the majority. Legal systems that respect their subjects' status as rational creatures with free wills permit their subjects to orient their own behavior. The principle of reason therefore requires substantive due process to ensure that laws provide dependable guideposts to individuals in orienting their behavior.
The principle of consent recognizes that the legitimacy of law derives from the consent of those subject to its power. Common law custom, the doctrine of stare decisis, and legislation sanctioned by the subjects' legitimate representatives all evidence consent.
The principle of autonomy establishes the authority of law. Laws must wield supremacy over political rulers, and political rulers must be subject to the same laws as other citizens. Political rulers may not arbitrarily alter the law to accord to their will.
Legal history demonstrates that, in the absence of a validity standard based on these principles, legal systems will not treat their subjects as ends in themselves. They will inevitably treat their subjects as mere means to other ends. Once laws do this, men have no rest from evil.
