Enterprise Systems (ES) have matured over the years, offering continuous improvement to the underlying technology and functionality, hence, it is reasonable to anticipate that organisations would upgrade their systems to realise the benefits of these improvements. However, the range of benefits and risks involved within upgrade projects, motivates only few organisations to upgrade; indicating that upgrade decision-making is not trivial, and requires a comprehensive consideration of the impacts, efforts, and benefits. To date, research on ES upgrade recommends practical guidance for managing and supporting upgrade projects, with few studies focusing on upgrade decision-making, yet the upgrade decision process remains one of the areas in post-implementation that is least explored. This research investigates the interrelated aspects of ES upgrade phenomena to explore the drivers and decision processes. A qualitative survey design was adopted to explore ES upgrade decision-making process and through web-based questionnaires and semi-structured interviews, qualitative data from 41 respondents representing 23 organisations was collected, coded, and analysed. Drawing from the Technology-Organisation-Environment (T-O-E) framework and process view of decision-making to theorise the findings, this research proposes an Upgrade Decision Support Model (UDSM) to represent ES upgrade decision-making process. The model comprises of two phases namely exploration and evaluation. The evaluation phase consists of two processes, which are objective assessment and strategy selection. In addition, objective assessment includes three sub-processes these are technical analysis, functional gap-fit analysis, and impact assessment. The study findings indicate that the decision to upgrade is an outcome of understanding the upgrade need, possible impacts, and benefits. Thus, asserting the importance of assessing the level of change, effort required and modifications to be reapplied prior to the upgrade decision. Additionally, the findings advocate that there is a relationship between upgrade drivers and the selection of an upgrade strategy, which guides the processes undertaken during the decision-making. This research contributes key insights on ES upgrade decision-making offering a thorough understanding of the drivers and processes. In addition, it presents decision makers with a methodical strategy for approaching upgrade decisions; hence, enables the identification of possible challenges and measures to overcome these issues.

Many higher education Institutions commit themselves to e-learning because they believe in its effectiveness as an alternative to traditional face to face methods of delivery, e-learning may to some extent increase enrolment and reduce training costs while allowing students the flexibility to attend classes at convenient times and places. University of Dar es salaam (UDSM) being the prime public university in Tanzania wants to adopt e-learning techniques in courses delivery; however the establishment of e-learning requires systematic planning, design, development and evaluation in order to achieve successful implementation. Therefore there is a need for the UDSM to address critical issues that might be faced by academics and the students in future.The aim of this study was to identify a culturally appropriate model inclusive of the most effective strategies and policies required for the establishment of an Open Distance e-learning (ODeL) centre at the University of Dar es salaam (UDSM). The study examined factors and conditions that reveal the importance of the development of an ODeL centre at the University of Dar es salaam, as well as analysing expertise (skills and knowledge) of the university’s academic and technical staff. It also examines existing models of similar centres from universities in both developed and developing countries. A mixed method was adopted where data was collected using a variety of tools: survey; interviews and content analysis.This study has indicated that the University of Dar es salaam can successfully develop an ODeL centre and implement e-learning if optimal capabilities of the selected media and technology are utilised effectively and efficiently. To support the development and delivery of e-learning a number of staff with a variety of skills and appropriate Information Communication Technology infrastructure are required. UDSM and other institutions wishing to participate in e-learning should review their educational policies and formulate strategies to ensure sustainability and quality of delivery.

The present study aims to investigate the chemical potential of Fusarium udum, an endophytic fungus isolated from Chrotalaria paulinea, which is responsible for causing damage to bean planting and species of Chrotalaria. The fungus was cultivated in four distinct culture media: PD (potato-dextrose), PDY (potato-dextrose-yeast), MPD (malt-peptone-dextrose), and Czapek. The culture time was determined by the glucose rate of the culture medium. The ethyl acetate extract from the microorganism cultivated in MPD (25 days) was selected for the pre-liminary chromatographic treatment, and led to the isolation of tyrosol, fusaric acid, and monaspilosin. In another experiment that used the culture media mentioned above, F. udum produced secondary metabolites through different days of incubation (7, 14, 21, 28 days). The chromatographic fractionation of the ethyl acetate extract from the microorganism cultured in PDY (28 days) provided cycle (L-Pro-L-Leu) and triptophol. The micellar extract obtained in this culture was also studied and it supplied the substance adenosine. Usual chromatographic techniques, including liquid-liquid partition, C-18 cartridge chromatography, and high perfor-mance liquid chromatography (HPLC), were used to isolate the secondary metabolites. The structural characterization was conducted by using the spectrometric techniques mass spec-trometry (MS) and nuclear magnetic resonance (NMR) with one and two-dimensional experi-ments and comparison with literature data.
O presente trabalho objetiva a investigação do potencial químico de Fusarium udum, um fungo endofítico isolado de Chrotalaria paulinea, e responsável por causar danos a plantações de feijão e em espécies de Chrotalaria. O fungo foi cultivado em quatro meios de cultura distintos: BD (batata-dextrose), BDL (batata-dextrose-levedura), MPD (malte-peptona-dextrose) e Czapek, sendo o tempo de cultivo determinado pela taxa de glicose do meio. O extrato AcOEt do micro-organismo cultivado em meio MPD (25 dias) foi selecionado para o tratamento cromatográfico preliminar, levando ao isolamento do tirosol, ácido fusárico e monaspilosina. Em um outro experimento, e utilizando os meios de cultivo mencionados, F. udum teve a produção dos metabólitos secundários acompanhada através de diferentes dias de incubação (7, 14, 21, 28 dias). O fracionamento cromatográfico do extrato AcOEt do micro-organismo cultivado em meio BDL (28 dias) forneceu a dicetopiperazina ciclo (L-Pro-L-Leu) e o triptofol. O extrato micelar obtido neste cultivo também foi estudado e forneceu a adenosina. Técnicas cromatográficas usuais, incluindo partição líquido-líquido, cromatografia em cartucho C-18 e cromatografia de alta eficiência (CLAE) foram utilizadas para o isolamento dos metabólitos secundários, enquanto que a caracterização estrutural foi possível através do uso de técnicas espectrométricas utilizando espectrometria de massa (EM) e ressonância magnética nuclear (RMN) com experimentos uni e bidimensionais, além de comparação com dados da literatura.

Cars are getting more technically advanced and more ECUs are being developed that results in increased safety and comfort, and a lower environmental impact. This leads to a complex work to test and verify that all the different ECUs are functioning as intended in various situations. Vehicle diagnostics often requires software from third parties that are often expensive. Syntronic AB are currently using software with a much larger functionality than needed to perform vehicle diagnostics and much of the unneces-sary functionality in the software leads to unnecessarily long runtimes for the program. By studying CAN and UDS and analyzing how they interact, I was able to create a software by systematically developing the software with two interfaces connected to each computer and continuously testing the implementation against the theoretical basis and then finally testing the software in a vehicle. The created software was better suited to the needs of the company and the more functionality-adapted software could perform the same diagnostics faster than the company’s current software. The most used UDS-service by the company could be implemented and the created software enabled more UDS services to be added without modifications of the main program or its features.Bilar blir allt mer tekniskt avancerade och fler ECU:er har utvecklats som har medfört ökad säkerhet och komfort samt minskad miljöpåverkan. Det resulterar i ett komplext arbete med att testa och verifiera att alla olika ECU:er fungerar som de skall i olika situationer. Fordonsdiagnostik kräver ofta program-varor från olika aktörer där licenserna ofta är dyra. Idag använder Syntronic AB en programvara med en mycket större funktionalitet än de behöver för att utföra fordonsdiagnostik och all denna onödiga funktionalitet i programvaran har medfört onödigt långa körtider. Genom att studera CAN och UDS och genom att analysera hur de samverkar kunde jag skapa en programvara genom att systematiskt utveckla programvaran med två gränssnitt inkopplade i var sin dator och kontinuerligt testa implementationen mot den teoretiska grunden för att slutligen testa programvaran i en bil. Den skapade programvaran var bättre anpassad för företagets behov och den mer funktionalitetsanpassade programvaran kunde utföra samma diagnostik snabbare än företagets nuvarande programvara. Den UDS-tjänst företaget använde mest kunde implementeras och den skapade programvaran konstruerades så att fler UDS-tjänster kunde läggas till utan modifikation av huvudprogrammet eller dess funktioner.

La tenue des barrages en remblai homogènes dépend fortement de la variation de teneur en eau du sol compacté, comme le montrent les ruptures d'ouvrages connues. Mais jusqu'à présent il n'existait pas de méthode permettant de relier le coefficient de sécurité à la teneur en eau. Le programme UDAM modélise le comportement de massifs de sols non saturés durant leur construction. Le modèle est composé de deux équations de conservation (eau et air) et d'une équation d'équilibre. Des surfaces d'états sont utilisées pour calculer l'indice des vides et le degré de saturation. La loi de comportement mécanique est celle de DUNCAN. La résolution numérique est composée d'une intégration en temps de type EULER semi-implicite et d'une discrétisation spatiale de type GALERKIN bidimensionnelle Ql. Dans ce mémoire, on abordera le calcul de bornes limitant le pas de temps. Un critère de pas de temps minimum limitant le domaine d'oscillation est calculé par une approche théorique sur la discrétisation. La borne supérieure est calculée pour garantir la stabilité du modèle. Le programme UDAM est ensuite validé sur trois cas de barrages différents (MIRGENBACH, La GANNE, El INFIERNILLO). Une démarche d'identification pour les paramètres de la surface d'état a été proposée. On trouvera aussi un essai de mise en eau des ouvrages. Enfin dans une partie informatique, on trouvera une description des notions intrinsèques du code, un pré-processeur graphique de traitement des résultats ainsi qu'un système de distribution des informations entre les différents outils périphériques.

Examensarbetet syftar till att undersöka möjligheten att expandera befintlig testprocess av elektroniska styrenheter. Hos Volvo Construction Equipment sker verifiering av styrenheter till stor del i riggar som består av större CAN-nätverk och innehåller många komponenter. Antalet riggar begränsas av att de är kostsamma, vilket i sin tur leder till att antalet tester som kan genomföras är begränsat. Målet med arbetet är att undersöka om det är möjligt att skapa en testmiljö som verifierar funktionalitet i en styrenhet, separerad från övriga delar av nätverket. Planen är att testmiljön ska kunna användas som komplement till de befintliga riggarna. Arbetet visar att det är möjligt genom att implementera en testmiljö som kan verifiera funktionalitet hos en separerad styrenhet. Testmiljön ger Volvo möjlighet att utföra fler tester och därmed expandera deras testprocess av elektroniska styrenheter.The thesis aims to examine the possibility of expanding the existing test process of Electronic Control Units. At Volvo Construction Equipment, verification of control units is mostly done in rigs that include large CAN-networks and contains multiple components. The number of rigs available is limited by their cost, which leads to a limited number of tests that can be made. The thesis is investigating whether it is possible to create a test environment that verifies functionality of an Electronic Control Unit, separated from the network. The purpose of the test environment is to be used as a complement to the existing rigs. The thesis shows that it is possible by implementing a test environment that can verify functionality of a separated control unit. This test environment allows Volvo to perform more tests and thereby expand their test process of Electronic Control Units.

The networking of control devices is well advanced in a modern automobile. To ensure secure communications with each other and to prevent mistakes due to communication error, protocol tests are performed at the physical and data link layer level. In a modern car the diagnosis of the electronic devices (e.g. reading/deleting fault memory entries) is done with a standardized communication protocol (UDS - Unified Diagnostic Services). Modern control units have this diagnostic capabilities to detect this communication error among others. This data is provided for a guided troubleshooting the vehicle via a defined interface. In this communication test detection mechanisms are specifically stimulated and read afterwards. In order to read or delete these entries, a diagnosis query is performed on the basis of the diagnostic protocol UDS. The diagnostic requests are currently performed with a diagnostic service of bus analysis software Vector CANoe. This service requests can be performed directly on CAN but for the diagnosis of other bus systems a software gateway is used. The maintenance required and the error rate of the software gateways is very high and should be replaced in the future. Furthermore, additional bus systems can be integrated only with great effort. Therfore the main aim of the master thesis was to develop a concept for univesal UDS API and afterwards implementation of that concept using CAPL programming for modular use in test environments for vehicle communication testing.

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 1998.Includes bibliographical references (leaf 29).
The electronics industry will endlessly seek higher performing electronic components that are smaller, lighter, and cheaper. Chip packaging is thought to be a solution. Ball Grid Array (BGA) packaging, a type of surface mount package, provides more 1/0 connections while increasing the reliability and decreasing the size of the electronics component. BGA packaging is an interconnection technology that uses an array of small uniform solder balls as the connection element between the chip and the circuit module or the circuit module and the card. The success of BGA packaging relies on the quality and the cost of the solder balls being used. Current solder ball production is of low yield and high cost, however, the Uniform Droplet Spray (UDS) process has proven itself to be an efficient method. Still, the electronics industry requires solder balls of higher sphericity. The present work investigates improvements made to the UDS process in order to increase the sphericity of the solder balls. The thesis begins by describing the motivation and importance of the current research. The theoretical analysis begins the process of designing two different collection containers. The containers are tested to determining their effectiveness. The first design exhibited balls with a 2% decrease in sphericity, while the second design exhibited balls with a 2% improvement in sphericity.

In an automotive context today’s need of testing functions while in factory, correcting faults in the workshop or adding extra value in the aftermarket makes it very important to easily be able to download new software to the electronic control units in vehicles. In the platform for standard automotive software development called AUTOSAR, two known protocols are presented to specify the procedure on how to implement this download operation: Unified Diagnostic Services (UDS) and the Universal Measurement and Calibration Protocol (XCP). However the part of the UDS and XCP standards that is about reprogramming is not completely a part of the AUTOSAR standard yet. In this thesis, UDS and XCP have been compared to evaluate which of the two that has most support in AUTOSAR today and are most likely to be fully integrated into AUTOSAR in the future. Since UDS already has support in AUTOSAR for some of the functions needed for reprogramming and because of the fact that UDS is a part of the extensively used On-board Diagnostic standard (OBD-II), UDS is chosen to be the most suitable protocol for implementing reprogramming functionality according to AUTOSAR. A bootloader with the ability to download data has been developed using only relevant functions from UDS and following the AUTOSAR specifications where it is applicable.För att kunna testa fordonsfunktioner i fabriken, åtgärda mjukvarufel under service eller för att uppgradera fordonet med nya funktioner är det viktigt att kunna ladda ner ny mjukvara till fordonets styrsystem. Den standardiserade mjukvaruplattformen för fordonsindustrin, AUTOSAR, innehåller två protokoll som båda specificerar hur mjukvara kan laddas ner: Unified Diagnostic Services (UDS) och Universal Measurement and Calibration Protocol (XCP). Tyvärr är de delarna av UDS och XCP som beskriver mjukvarunerladdning inte en del av AUTOSAR än. I det här examensarbetet har UDS och XCP jämförts för att utvärdera vilken av de båda som i dagsläget har störst stöd för nerladdning av mjukvara i AUTOSAR och vilken som troligast kommer att bli en del av AUTOSAR i framtiden. Eftersom AUTOSAR redan stödjer några av de funktioner i UDS som behövs för nerladdning av mjukvara samt på grund av att UDS är en del av branschstandarden för fordonsdiagnostik OBD-II, har UDS valts som den mest lämpade att i dagsläget användas för att implementera nerladdning av mjukvara enligt AUTOSAR. En bootloader som stödjer nerladdning av mjukvara via UDS har sedan implementerats enligt AUTOSAR-specifikationen så långt som möjligt.

Pour répondre aux enjeux environnementaux (changement climatique, couche d'ozone...) et à l'accroissement des besoins de réfrigération (besoins sanitaires, agro-alimentaire, de confort...), la réfrigération électrocalorique est une alternative prometteuse : elle permet d'éviter l'utilisation des fluides réfrigérants nocifs pour l'environnement employés dans les réfrigérateurs conventionnels. L'effet électrocalorique est la variation de la température d'un matériau polaire suite à l'application ou la suppression d'un champ électrique. Cette thèse avait deux objectifs : le premier était l'élaboration et la caractérisation d'un matériau électrocalorique original, et le deuxième était de concevoir un démonstrateur de réfrigération électrocalorique. Ainsi, un nouveau matériau électrocalorique à base de titanate de baryum dopé par du samarium avec différents taux de concentration a été élaboré et ses propriétés microstructurales, thermiques, diélectriques et ferroélectriques ont été caractérisées. L'effet du taux de concentration en samarium dans les sites A de la structure pérovskite du BaTiO3 sur la température de transition ferroélectrique/paraélectrique a pu être mis en évidence. L'étude des propriétés électrocaloriques en fonction de la température et de l'intensité du champ électrique a été réalisée par mesure directe du flux de chaleur électrocalorique généré ou absorbé suite à l'application ou la suppression du champ électrique. Nous avons utilisé pour cela un calorimètre adiabatique développé au sein du laboratoire et adapté à l'étude de l'effet électrocalorique. Cette étude préliminaire a permis de mettre en évidence un effet électrocalorique même pour des champs faibles et l'influence de la température et de la concentration en samarium sur l'intensité de cet effet. Par ailleurs, un démonstrateur de réfrigération électrocalorique a été mis au point, les premiers résultats obtenus ont permis d'évaluer et de discuter les différentes solutions techniques proposées. Nous avons ainsi pu montrer la faisabilité de l'utilisation de l'effet électrocalorique pour la réfrigération, validant ainsi l'idée de l'exploitation de l'effet électrocalorique comme une solution alternative aux techniques usuelles de réfrigération. De par sa conception, ce démonstrateur peut être envisagé comme un banc d'essai permettant l'optimisation des propriétés des matériaux et des processus associés dans le cadre d'une application de l'effet électrocalorique pour la réfrigérationTo answer to the environmental issues (global warning, pollution), electrocaloric cooling can be considered as a promising approach as an environment friendly alternative to the conventional refrigeration other techniques. It avoids the use of environment harmful refrigerant used in conventional refrigerators. Electrocaloric effect is the charge of temperature of a polar material when an electric field is applied or removed. This thesis had two objectives. Firstly, the elaboration and characterization of an original electrocaloric material, and then the conception of an electrocaloric refrigeration demonstrator device. Thus a new electrocaloric material based on samarium doped barium titanate has been elaborated and its structural, thermal, electrical and ferrolectrical properties have been characterized. The effect of the dopant (samarium) amount on the ferroelectric/paraelectric transition temperature has been confirmed. The characterization of the electrocaloric properties as a function of temperature and electric field intensity have been realized by direct measurement of the isothermal heat flux upon application and removal of the electric field using a homemade calorimeter. Preliminary results showed that an electrocaloric effect can be detected even for low electric field intensity, and evidenced the effect of the temperature and the electric field intensity on the magnitude of the electrocaloric effect. Then an electrocaloric refrigeration device has been developed and built, first results allowing to evaluate the different solutions we have selected for the conception of the demonstrator. They showed that the electrocaloric effect can be used as an alternative to the conventional solutions for the refrigeration. By its conception, the device may also be considered as a testing bench for the optimization of the materials properties and associated process in Electrocaloric refrigeration applications

This study attempted to find out how mobile technologies could be used to implement Web 2.0 based service delivery to graduate students based in the Graduate School of the University for Development Studies (UDS) Library. A 23 item questionnaire was administered to a sample of 155 participants who were selected by means of simple random sampling. A total of 119 questionnaires were retrieved and found to be adequate for analysis and interpretation. The collected data was analyzed and interpreted using the SPSS package and Microsoft Excel and was presented in the form of text and graphs. Findings indicated that graduate students overall had very good abilities with regards to the usage of the Web 2.0 applications; that they will like to access their library’s resources through the Web 2.0 applications using their mobile devices and the services they will like to access include reference services, circulation services, searching the OPAC, accessing library news, e-resources and subject guides in that order. There are varied kinds of mobile library services, examples of which are MOPACs, mobile reference, mobile instruction, mobile collection and mobile tours. However, the UDS Library does not provide any Web 2.0 mobile based services. The main challenges in implementing these Web 2.0 mobile based services include cost of Internet access, slow Internet connectivity and insufficient funds to acquire needed equipment. Based on these findings, some recommendations were given.Mini Dissertation (MIT)--University of Pretoria, 2014.

The centrepiece of this thesis is a deep, new, high-resolution 1.4-GHz image covering the United Kingdom Infrared (IR) Telescope IR Deep Sky Survey (UKIDSS) Ultra Deep Survey (UDS) legacy field. Deep pseudo-continuum observations were made using the Very Large Array, prior to its recent upgrade, in its A, B and DnC configurations. The resulting mosaic has a full-width-at-half-maximum synthesised beam width of ≈ 1.7 arcsec and a point-source sensitivity of ≈ 60μJy (6σ ) across the central 0.6 deg2, while conserving flux from sources of extended emission. The full image covers 1.3 deg2. I also present a catalogue containing over 1,000 radio emitters, having chosen the 6-σ threshold by maximising the number of radio sources with secure optical/near-IR counterparts. Most of the sources in the catalogue (≈ 90 per cent) lie in the sub-mJy flux density regime. Deep, complementary data covering a wide range of wavelengths was used to explore this faint radio population, whose nature remains controversial. It was found that 53 per cent of the sample comprise active galactic nuclei (AGN). AGN dominate at & 0.2mJy and remain a significant population down to 0.1mJy; at lower fluxes – the so-called μJy radio population – star-forming galaxies become dominant. The radio sample presented here was also matched to Hubble Space Telescope imaging of the UDS field (which is part of the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey – CANDELS) to classify the faint radio population morphologically. These classifications were done using the Gini–M20 method. It was found that a low fraction of AGN and SFGs are undergoing interactions and mergers, 33 ± 9 and 13 ± 7 per cent, respectively. The merger fraction does not appear to have evolved significantly since z ∼ 3. This suggests that mergers have played a relatively minor role in the assembly of galaxies and super-massive black holes – certainly less significant than previously thought. Finally, I present a study of cosmic star-formation activity as a function of stellar mass and redshift, exploiting panchromatic stacking. Mid-IR–through–radio images, including new data from Herschel, are stacked at the positions of a K-selected (i.e. an approximately mass-selected) sample in the UDS field. Specific star-formation rates (SSFR, i.e. star-formation rate per stellar mass, or the rate at which a galaxy is converting its gas into stars) were derived from UDS radio luminosities measured here and stellar masses from the literature. The SSFR was found to be poorly correlated with stellar mass; it decreases with decreasing redshift; at a given mass, SSFR rises with redshift. These results indicate that at early epochs, galaxies were forming stars more efficiently and at a higher rate.

La grippe est une infection respiratoire responsable de complications respiratoires ou neurologiques nécessitant une prise en charge rapide et adaptée. L’émergence des technologies de séquençage à haut débit (NGS) permet l’étude des communautés microbiennes résidentes ainsi qu’une étude approfondie du génome des pathogènes impliqués. Cette thèse a pour objectif de caractériser le microbiome respiratoire et la diversité génomique virale des patients infectés par les virus grippaux, en corrélant les données clinicobiologiques recueillies. Après recueil des prélèvements respiratoires d’enfants hospitalisés entre 2010 et 2014, le séquençage de leur microbiome respiratoire a mis en évidence une augmentation de la diversité microbienne ainsi qu’une signature microbienne différentielle entre formes cliniques. Une répartition différentielle de taxons (OTU) permet la prédiction de complications chez les enfants infectés. L’étude d’échantillons respiratoires de patients adultes permettra de compléter la signature prédictive. Après validation des processus analytiques et bioinformatiques par reconstitution artificielles de quasi espèces et recueil de 125 prélèvements cliniques respiratoires, le séquençage du génome entier par NGS des virus grippaux permet de différencier les diversités initiales en fonction de la nature du virus infectant et de la complication. En comparaison du prélèvement initial précoce les échantillons prélevés successivement mettent en évidence une diversification différentielle entre les différents segments des virus grippaux infectant les patients, que ce soit chez les patients immunocompétents ou chez un patient immunodéprimé à l’excrétion prolongéInfluenza is a respiratory infection responsible for respiratory or neurological complications and require rapid and adapted management. The emergence of next-generation sequencing (NGS) allows the study of resident microbial communities as well as an in-depth study of the genome of the pathogens. This thesis aimed to characterize the respiratory microbiome and the viral genomic diversity of influenza virus infected patients, correlating these data to the collected clinical data. After sampling of respiratory specimens from hospitalized children between 2010 and 2014, the sequencing of their respiratory microbiome revealed an increase in microbial diversity and a differential microbial signature between clinical forms. A differential taxon distribution (OTU) allows the prediction of complications in infected children. The study of adult respiratory samples will complete the predictive signature.After validation of the analytical and bioinformatic processes by artificial reconstitution of quasi-species and collection of 125 respiratory clinical specimens, the sequencing of the whole genome by NGS of the influenza viruses allow to differentiate the initial diversities according to the nature of the infecting virus and the complication. Compared to early samples, specimen sampled successively show a differential diversification between the different segments of influenza viruses, whether in immunocompetent patients or in an immunocompromised patient with prolonged excretion

The aim of this thesis project is to explore a network traffic regulator using bandwidth management techniques that regulates data traffic with the objective to use the network bandwidth to its maximum capacity while ensuring that the network is not overloaded. The bandwidth in the existing network architecture is shared between two co-existing, distinct data flows for on-board communication and diagnostic communication in an in-vehicle network. The diagnostic communication must not interfere with the more critical on-board communication and it should comply with the remaining bandwidth. In the existing solution, fixed delays are imposed on the data traffic which result in a waste of network capacity. The approach presented in this thesis uses two regulation algorithms for different types of diagnostic services. One regulation algorithm is activated for diagnostic services that require data segmentation and multiple data frames to accommodate the transferred data. This algorithm makes use of the Flow Control parameter Separation Time specified in ISO 15765-1:2011 "Road vehicles -- Diagnostic communication over Controller Area Network (DoCAN)". The other algorithm regulates diagnostic services that generate bursts of single frames where data segmentation is not required and it does so using traffic shaping techniques. The results in this thesis show that the network traffic indeed can be regulated for different diagnostic services by using the two mentioned regulation algorithms. The results also show that data is not lost due to high network utilisation and that the bandwidth is used to its maximum capacity without having to impose fixed delays on the network system. The regulator is adaptive in the sense that it can be used for different vehicle configurations with compatible network systems to ensure quality of service and a robust network system.I detta examensarbete är målet att utforska en metod för att reglera nätverkstrafik genom att använda tekniker inom bandbreddshantering med syfte att utnyttja bandbredden till dess maximala kapacitet utan att överbelasta nätverket. Bandbredden i den nuvarande nätverksarkitekturen delas mellan två dataflöden för onboard kommunikation och diagnostisk kommunikation. Den diagnostiska kommunikationen får inte på någotvis störa onboard kommunkationen och får anpassa sig till den bandbredd som kvarstår. I det existerande systemet införs fixa fördröjningar i nätverkstrafiken vilket medför ett onödigt slöseri på nätverkskapaciteten och som också medför att de diagnostiska tjänsterna tar längre tid att utföra. Tillvägagångssättet som presenteras i detta arbete använder två regleringsalgoritmer för olika typer av diagnostiska tjänster. En algoritm används för tjänster som kräver datasegmentering och flera dataramar för att skicka data. Den här algoritmen använder parametern Separation Time som är specificerad i ISO standarden 15765-1:2011 "Road vehicles -- Diagnostic communication over Controller Area Network (DoCAN)". Diagnostiska tjänster som istället genererar en skur av enstaka dataramar regleras med en traffic shaping algoritm som heter Token Bucket. Resultaten i detta arbete visar att det går att reglera nätverkstrafiken för olika typer av diagnostiska tjänster genom att använda de två utvecklade algoritmerna. Resultaten visar också att data inte går förlorat vid höga nätverkslaster och att bandbredden används maximalt utan att behöva införa fixa fördröjningar i nätverkssystemet. Regleraren är adaptiv i bemärkelsen att den kan användas för alla tänkbara fordonskonfigurationer med kompatibelt nätverkssystem för att försäkra quality of service och robusthet.

Aggressive scaling of CMOS circuits in recent times has lead to dramatic increase in leakage currents. Previously, sub-threshold leakage current was the only leakage current taken into account in power estimation. But now gate leakage and reverse biased junction band-to-band-tunneling leakage currents have also become significant. Together all the three types of leakages namely sub-threshold leakage, gate leakage and reverse bias junction band-to-band tunneling leakage currents contribute to more than 25% of power consumption in the current generation of leading edge designs. Different sources of leakage can affect each other by interacting through resultant intermediate node voltages. This is called loading effect and it leads to further increase in leakage current. On the other hand, sub-threshold leakage current decreases as more number of transistors is stacked in series. This is called stack effect. Previous works have been done that analyze each type of leakage current and its effect in detail but independent of each other. In this work, a pattern dependent steady state leakage estimation technique was developed that incorporates loading effect and accounts for all three major leakage components, namely the gate leakage, band to band tunneling leakage and sub-threshold leakage. It also considers transistor stack effect when estimating sub-threshold leakage. As a result, a coherent leakage current estimator tool was developed. The estimation technique was implemented on 65nm and 45nm CMOS circuits and was shown to attain a speed up of more than 10,000X compared to HSPICE. This work also extends the leakage current estimation technique in Field Programmable Gate Arrays (FPGAs). A different version of the leakage estimator tool was developed and incorporated into the Versatile Place & Route CAD tool to enable leakage estimation of design after placement and routing.
Leakage current is highly dependent on the steady state terminal voltage of the transistor, which depends on the logic state of the CMOS circuit as determined by the input pattern. Consequently, there exists a pattern that will produce the highest leakage current. This work considers all leakage sources together and tries to find an input pattern(s) that will maximize the composite leakage current made up of all three components.
This work also analyzes leakage power in presence of dynamic power in a unique way. Current method of estimating total power is to sum dynamic power which is ½&#;CLVDD2f and sub-threshold leakage power. The dynamic power in this case is probabilistic and pattern independent. On the other hand sub-threshold leakage is pattern dependent. This makes the current method very inaccurate for calculating total power. In this work, it is shown that leakage current can vary by more than 8% in time in presence of switching current.

The speed of operation has increased to a greater extent by properly scaling of the CMOS technology, still the issue of leakage currents are leftover as a contrary issue. The issue has taken a severe shift as the scaling enhances into ultra-deep-submicron (UDSM) region. And as the process technology turns into the better state with increment in the device density, it also contributed a lot in increasing the leakage power. As the value of supply voltage decreases, gate oxide thickness reduces which further decrease the value of threshold voltage which contributed in preserving the performance of the circuit. But the main drawback of decreasing the threshold voltage is that the value of leakage power dissipation increases significantly. These unwanted leakage current must be lowered down for proper working of the circuit. So, the proper designing of those nano- CMOS Circuits which provides leakage current free performance advantage and this is the most difficult designing strategy in present era. In this work, we address the issue of leakage power and presents a circuit technique to mitigate the leakage power which in turns reduces the static power dissipation to a greater extent. In the proposed circuits, the static power dissipation is reduced to a greatest extent In popular circuits like SRAM, flip flops by using various techniques like forced stack technique, sleepy stack technique, sleep transistor technique and LECTOR technique. The circuits are implemented using the SymicaDE and LTspice software at PTM models 45nm, and 90nm and the result is compared with the existing techniques, which finally concluded that by using these techniques the leakage power can be decreased to a noteworthy degree.

The star formation history is a key-element to understand galaxy evolution and formation. Recent studies have shown that the star-formation rate peaks at redshift z=1-3 and then decline to its local value. The physical processes responsible for the sudden quenching of star-formation are still unknown. In order to better understand the origin of these effects, we propose in this study to use the UV-luminosity as an indicator of the Star-formation rate. We take advantage of our deep NIR/optical data from the UKIDSS-UDS/SXDS survey and our very deep CFHT U-band data to compute the luminosity function of galaxies at z=1-3. Then we fit a Schechter function and integrate to compute the luminosity density to explore the evolution of the star-formation rate.

The networking of control devices is well advanced in a modern automobile. To ensure secure communications with each other and to prevent mistakes due to communication error, protocol tests are performed at the physical and data link layer level. In a modern car the diagnosis of the electronic devices (e.g. reading/deleting fault memory entries) is done with a standardized communication protocol (UDS - Unified Diagnostic Services). Modern control units have this diagnostic capabilities to detect this communication error among others. This data is provided for a guided troubleshooting the vehicle via a defined interface. In this communication test detection mechanisms are specifically stimulated and read afterwards. In order to read or delete these entries, a diagnosis query is performed on the basis of the diagnostic protocol UDS. The diagnostic requests are currently performed with a diagnostic service of bus analysis software Vector CANoe. This service requests can be performed directly on CAN but for the diagnosis of other bus systems a software gateway is used. The maintenance required and the error rate of the software gateways is very high and should be replaced in the future. Furthermore, additional bus systems can be integrated only with great effort. Therfore the main aim of the master thesis was to develop a concept for univesal UDS API and afterwards implementation of that concept using CAPL programming for modular use in test environments for vehicle communication testing.

La modélisation numérique est devenue un outil indispensable qui permet la prise en compte de structures de plus en plus complexes. De nombreuses méthodes numériques ont été développées puis évoluées pour être adaptées au problème à résoudre. Parmi ces méthodes, la TLM (Transmission Line Matrix) est très connue par son efficacité dans la modélisation des structures en hyperfréquence. Nous nous sommes intéressés dans ce travail à la méthode FD-TLM, l'approche fréquentielle de la TLM. La formulation adoptée est dérivée de la TLM dans le domaine temporel moyennant une transformée de Fourier. Cette étude a englobé plusieurs aspects de la méthode en commençant par la présentation des principaux noeuds utilisés dans le maillage avant de passer à l'étude et l'analyse de l'erreur de vitesse dans la FD-TLM. Par la suite, une grande partie de ce travail a été consacrée à l'étude des parois absorbantes particulièrement les PML (Perfecly Matched Layers) et les opérateurs d'onde unidirectionnels qui ont présenté d'excellentes performances d'absorption. Finalement, dans le but d'une étude d'optimisation, la FD-TLM a été combinée à la méthode de segmentation permettant de subdiviser la structure en plusieurs sous-domaines qui peuvent être isolés et maillés séparément.

Des écrits scientifiques mettent en évidence les retombées de l’humanisation et de la déshumanisation des soins pour les patients. Les formateurs et les chercheurs mettent donc à l’essai de nombreuses stratégies pédagogiques prometteuses qui visent à promouvoir l’humanisation des soins. Or, les connaissances portant sur le processus d’apprentissage de la compétence « agir avec humanisme » demeurent peu développées.
Cette thèse doctorale présente une étude phénoménologique qui visait à élaborer un modèle cognitif de l’apprentissage (MCA) de la compétence « agir avec humanisme », à partir de l’expérience vécue d’apprentissage d’étudiantes infirmières et de diplômées d’un programme de baccalauréat en sciences infirmières basé sur une approche par compétences, et à identifier les indicateurs de développement s’y rattachant. L’étude a été orientée par une perspective conceptuelle intégrant les sciences infirmières, soit le Modèle humaniste des soins infirmiers – UdeM (MHSI-UdeM) développé par Cara et al. (2016), et les sciences de l’éducation, soit la conception du développement des compétences de Tardif (2006). La philosophie humaniste, à la base du MHSI-UdeM, a été approfondie et analysée à la lumière de cinq conceptions infirmières. Une analyse du MHSI-UdeM selon la méthode de Chinn et Kramer (2018) a également été réalisée.
La phénoménologie interprétative de Benner (1994), ancrée dans les référents philosophiques d’Heidegger (1927/2008), a été privilégiée. Les participantes (n = 26), des étudiantes et des infirmières, ont été recrutées dans six groupes en fonction de leur progression universitaire et professionnelle. Des entrevues individuelles ont été conduites puis les récits recueillis ont été transcrits et analysés selon une opérationnalisation de la perspective phénoménologique de Benner (1994).
Le MCA de la compétence « agir avec humanisme » a été décliné en cinq niveaux de développement suivants : 1) conscientisation à l’humanisation des soins, 2) appropriation d’habiletés de communication investies dans une approche humaniste, 3) conciliation d’un idéal de pratique humaniste aux responsabilités de l’infirmière clinicienne, 4) intégration d’une approche humaniste dans l’ensemble des soins et 5) maîtrise d’une approche humaniste dans l’environnement de travail. D’autres résultats ont montré qu’un développement de la compétence « agir avec humanisme » commençait avant les études en sciences infirmières et qu’il était différent d’une étudiante à l’autre.
Les résultats ont aussi mis en évidence des leviers et des contraintes au développement de la compétence « agir avec humanisme », résidant à la fois dans les institutions d’enseignement et les établissements de santé. Il y avait notamment la présence de modèles de rôle humanistes et d’environnements qui promeuvent l’humanisation des soins, ainsi que la surcharge de travail qui l’entrave. Les participantes ont aussi énoncé des recommandations visant à optimiser le développement de la compétence « agir avec humanisme » qui se sont avérées fortement cohérentes avec les leviers et les contraintes identifiées.
Des retombées pour les cinq domaines de la pratique infirmière découlent de cette étude et offrent certaines pistes qui pourraient favoriser le développement de la compétence « agir avec humanisme ». L’une d’elles vise à harmoniser l’entrée dans la profession infirmière après la formation, une période charnière où le développement de la compétence « agir avec humanisme » s’est avéré être le plus vulnérable.Several papers illustrate the outcomes of humanization and dehumanization of care for patients. Educators and researchers are testing many promising educational strategies aimed at promoting humanization of care. However, little is known about the development of the “humanistic caring” competency. This thesis presents a phenomenological study aimed at elaborating a cognitive learning model (CLM) of the “humanistic caring” competency, from the lived experiences of nursing students and graduates of a competency-based program, and to identify related developmental indicators. A conceptual perspective combining nursing, the Humanistic Model of Nursing Care – UdeM (HMNC-UdeM) developed by Cara et al. (2016), and education, a conception about competency development (Tardif, 2006), oriented the study. The humanistic philosophy at the roots of the HMNC-UdeM was scrutinized and analyzed in the context of five conceptual models. An analysis of the HMNC-UdeM, based on Chinn and Kramer’s method (2018), was also carried out. Benner’s (1994) interpretive phenomenology, grounded in the philosophical foundations of Heidegger (1927/2008), was used as the study methodology. The participants (n = 26), students and nurses, were recruited into six groups based on their progression in the education program and their clinical experience. Individual interviews were conducted, and the stories collected were transcribed and analyzed according to an operationalization of Benner’s (1994) phenomenological perspective. The CLM of the “humanistic caring” competency comprised five developmental stages: 1) conscientization to humanization of care, 2) assimilation of communication skills integrated in a humanistic approach, 3) reconciliation of an ideal of humanistic practice with the responsibilities of a nurse, 4) integration of a humanistic approach in nursing care, and 5) mastery of a humanistic approach in the work environment. Other results showed that a development of "humanistic caring" began before studying nursing and that it was different from one student to another. The results also highlighted facilitators and constraints to the development of "humanistic caring" residing in both educational institutions and healthcare facilities. These included the presence of humanistic role models and environments that promote humanization of care, and the work overload, that impedes it. The participants also suggested recommendations aimed at optimizing the development of "humanistic caring", and these were highly consistent with the aforementioned facilitators and constraints. Implications for the five domains of practice emerge from this study and offer some avenues that could promote the development of "humanistic caring". One of them is to facilitate the entry into the nursing profession after graduation, a turning point where the development of "humanistic caring" has proven to be the most vulnerable.

Abstract This thesis focuses on the situation of a substantial subject in the historical development of the surrealist experience and confronts it with our original postmodern interpretation of thoughts of early Marx. The surrealist consciousness is based on a dialectical opposition between rational and irrational elements of cognitive processes. André Breton apprehends this dialectics under the perspective of love life and relates it to values of love, freedom and poetry. Nevertheless, this conception changes in the immanent development of the surrealist consciousness from Breton over the work and thoughts Salvador Dalí and Mikuláš Medek to Vratislav Effenberger. Effenberger removes positive values from surrealism and puts emphasis on the critical functions of the irrational. On the psychological field, all these ideas are based on the conception of the unconscious which means there is the substantial approach in them. Our critical interpretation of Marx shows, that the surrealist concept of subject is in the contradiction with its substantial determination. The subject has to be perceived as the essential...

Indiana University-Purdue University Indianapolis (IUPUI)Oral health is crucial to overall health and a focus of the U.S. Health Center program, which provides preventive dental services in medically underserved communities. Dental hygiene is an oral health profession whose practice is focused on dental disease prevention and oral health promotion. Variations in the practice and regulation of dental hygiene has been demonstrated to influence access to dental care at a state level; restrictive policies are associated lower rates of access to care. Understanding whether and to what extent policy variations affect availability and access to dental care and the oral health of medically underserved communities served by grantees of the U.S. Health Center program is the focus of this study. This longitudinal study examines dental service utilization at 1,135 health center grantees that received community health center funding from 2004 to 2011. The Dental Hygiene Professional Practice Index (DHPPI) was used as an indicator of the state policy environment. The influence of grantee and state level characteristics are also considered. Mixed effects models were used to account for correlations introduced by the multiple hierarchical structure of the data. Key findings of this study demonstrate that state policy environment is a predictor of the availability and access to dental care and the oral health status of medically underserved communities that received care at a grantee of the U.S. Health Center program. Grantees located in states with highly restrictive policy environments were 73% less likely to deliver dental services and, those that do, provided care to 7% fewer patients than those grantees located in states with the most supportive policy environments. Population’s served by grantees from the most restrictive states received less preventive care and had greater restorative and emergency dental care needs. State policy environment is a predictor of availability and access to dental care and the oral health status of medically underserved communities. This study has important implications for policy at the federal, state, and local levels. Findings demonstrate the need for policy and advocacy efforts at all levels, especially within states with restrictive policy environments.
