More complex and intricate Computer Vision algorithms combined with higher resolution image streams put bigger and bigger demands on processing power. CPU clock frequencies are now pushing the limits of possible speeds, and have instead started growing in number of cores. Most Computer Vision algorithms' performance respond well to parallel solutions. Dividing the algorithm over 4-8 CPU cores can give a good speed-up, but using chips with Programmable Logic (PL) such as FPGA's can give even more. An interesting recent addition to the FPGA family is a System on Chip (SoC) that combines a CPU and an FPGA in one chip, such as the Zynq-7000 series from Xilinx. This tight integration between the Programmable Logic and Processing System (PS) opens up for designs where C programs can use the programmable logic to accelerate selected parts of the algorithm, while still behaving like a C program. On that subject, Xilinx has introduced a new High-Level Synthesis Tool (HLST) called Vivado HLS, which has the power to accelerate C code by synthesizing it to Hardware Description Language (HDL) code. This potentially bridges two otherwise very separate worlds; the ever popular OpenCV library and FPGAs. This thesis will focus on evaluating Vivado HLS from Xilinx primarily with image processing in mind for potential use on GIMME-2; a system with a Zynq-7020 SoC and two high resolution image sensors, tailored for stereo vision.

Nous proposons une méthode supervisée de détection de chutes de personnes en temps réel, robusteaux changements de point de vue et d’environnement. La première partie consiste à rendredisponible en ligne une base de vidéos DSFD enregistrées dans quatre lieux différents et qui comporteun grand nombre d’annotations manuelles propices aux comparaisons de méthodes. Nousavons aussi défini une métrique d’évaluation qui permet d’évaluer la méthode en s’adaptant à la naturedu flux vidéo et la durée d’une chute, et en tenant compte des contraintes temps réel. Dans unsecond temps, nous avons procédé à la construction et l’évaluation des descripteurs spatio-temporelsSTHF, calculés à partir des attributs géométriques de la forme en mouvement dans la scène ainsique leurs transformations, pour définir le descripteur optimisé de chute après une méthode de sélectiond’attributs. La robustesse aux changements d’environnement a été évaluée en utilisant les SVMet le Boosting. On parvient à améliorer les performances par la mise à jour de l’apprentissage parl’intégration des vidéos sans chutes enregistrées dans l’environnement définitif. Enfin, nous avonsréalisé, une implantation de ce détecteur sur un système embarqué assimilable à une caméra intelligentebasée sur un composant SoC de type Zynq. Une démarche de type Adéquation AlgorithmeArchitecture a permis d’obtenir un bon compromis performance de classification/temps de traitement / We propose a supervised approach to detect falls in home environment adapted to location andpoint of view changes. First, we maid publicly available a realistic dataset, acquired in four differentlocations, containing a large number of manual annotation suitable for methods comparison. We alsodefined a new metric, adapted to real-time tasks, allowing to evaluate fall detection performance ina continuous video stream. Then, we build the initial spatio-temporal descriptor named STHF usingseveral combinations of transformations of geometrical features and an automatically optimised setof spatio-temporal descriptors thanks to an automatic feature selection step. We propose a realisticand pragmatic protocol which enables performance to be improved by updating the training in thecurrent location with normal activities records. Finally, we implemented the fall detection in Zynqbasedhardware platform similar to smart camera. An Algorithm-Architecture Adequacy step allowsa good trade-off between performance of classification and processing time

Inledning: I Länsstyrelsen Blekinges projekt TBU, som står för tobaksfria barn och unga i Blekinge, har ambassadörer från gymnasiet använts för att nå ut med information om tobak till ungdomar i högstadiet. Arbetet med ambassadörer relaterar till metoden peer education som innebär att jämlikar utbildar jämlikar. Att använda jämlikar som är lik målgruppen i exempelvis ålder eller erfarenheter innebär en annan inlärningssituation än den som sker mellan till exempel lärare och elev. Syfte: Syftet med studien var att undersöka ambassadörernas arbete med peer education som tobaksprevention samt hur ambassadörer kunde påverkas av arbetet som peer educators. Metod: Metoden som använts i studien är intervjuer med ambassadörer samt en fokusgruppsintervju med TBU:s projektgrupp. Det insamlade empiriska materialet analyserades genom innehållsanalys. Resultat: Resultatet visar att ambassadörerna hade, eller utvecklade, ett intresse för sitt arbete och en förmåga att kommunicera med sin målgrupp, vilket de även nämnde som viktiga delar i rollen som ambassadör. Ambassadörerna hade också påverkats av sitt arbete, bland annat i form av stärkta kommunikationsförmågor och ökad kunskap, vilket även ansågs bero till största del på att ambassadörerna fick genomgå en utbildning innehållande olika delar och perspektiv. Konklusion: Det viktigaste i ambassadörernas arbete för att förebygga tobaksbruket hos högstadieelever var den utbildning som ambassadörerna fick under den första veckan av sitt arbete. Vi föreslår därför att TBU utvecklar ett konkret underlag för utbildningen med tydliga metoder och mål som tar hänsyn till att utveckla ambassadörernas intresse för ämnet och kommunikationsförmågor. Fortsatta studier kan förslagsvis undersöka hur högstadieeleverna upplevde relationen mellan ambassadörerna och dem. / Introduction: In the project known as TBU, tobacco free adolescents in Blekinge, ambassadors in the ages 16-19 have been used for spreading information about tobacco to adolescents in the ages 13-15. This approach is related to the method peer education. The use of peers who are close in age or have similar experiences represents another way of learning than the more common situation between a teacher and a student. Objective: The objective of this study was to examine how ambassadors use peer education as tobacco prevention and how the ambassadors could be affected by their work as peer educators. Method: The methods used in this study were interviews with the ambassadors and a focus group interview with the project group of TBU. The material was analysed with a content analysis. Results: The results show that the ambassadors had, or had developed, an interest for their work and an ability to communicate with their target group, which they also stated as important parts of the role as an ambassador. The ambassadors had also been affected by their work. Their communication skills had been improved and they had had an increase in knowledge, which was thought to be a result of their education containing different parts and perspectives. Conclusion: The most important in the work of the ambassadors to prevent the use of tobacco in adolescents was the education the ambassadors had the first week of their work period. Therefore, we suggest that TBU develops a concrete material for the education with well- defined methods and targets which would aim to develop the ambassadors interest for the subject and their communication skills. Further studies could examine the relationship between students and ambassadors from the student's perspective.

Les systèmes embarqués sur puce (SoC) envahissent notre vie quotidienne. Avec les progrès technologiques, ils intègrent de plus en plus de fonctionnalités complexes impliquant des charges de calcul et des tailles de mémoire importantes. Alors que leur complexité est une tendance clé, la consommation d’énergie est aussi devenue un facteur critique pour la conception de SoC. Dans ce contexte, nous avons étudié une approche de modélisation au niveau transactionnel qui associe à un modèle fonctionnel SystemC-TLM une description d’une structure de gestion d’un arbre d’horloge décrit au même niveau d’abstraction. Cette structure développée dans une approche de séparation des préoccupations fournit à la fois l’interface pour la gestion de puissance des composants matériels et pour le logiciel applicatif. L’ensemble des modèles développés est rassemblé dans une librairie ClkARCH. Pour appliquer à un modèle fonctionnel un modèle d’un arbre d’horloge, nous proposons une méthodologie en trois étapes : spécification, modélisation et simulation. Une étape de vérification en simulation est aussi considérée basée sur des contrats de type assertion. De plus, nos travaux visent à être compatibles avec des outils de conception actuels. Nous avons proposé une représentation d’une structure de gestion d’horloge et de puissance dans le standard IP-XACT permettant de produire les descriptions C++ des structures de gestion de puissance du SoC. Enfin, nous avons proposé une approche de gestion de puissance basée sur l’observation globale des états fonctionnels du système dans le but d’éviter ainsi des prises de décisions locales peu efficaces à une optimisation de l’énergie. / Embedded systems-on-chip (SoC) invade our daily life. With advances in semiconductor technology, these systems integrate more and more complex and energy-intensive features which generate increasing computation load and memory size requirements. While the complexity of these systems is a key trend, energy consumption has emerged as a critical factor for SoC designers. In this context, we have studied a modeling transactional level approach allowing a description of a clock tree and its management structure to be associated with a functional model, both described at the same abstraction level. This structure developed in a separation of concerns approach provides both the interface to the power consumption management of the hardware components and the application software. All the models developed are gathered in a C++ ClkArch library. To apply to a SystemC-TLM architecture model a clock tree intent with its control part, we propose a methodology based on three steps: specification, modeling and simulation. A verification step based on simulation is also considered using contracts of assertion type. This work aims to build a modelling approach on current design tools. So we propose a representation of a clock and power management structure in the IP-XACT standard allowing a C++ description of the SoC power management structures to be generated. Finally, a power management strategy based on the global functional states of the components of the system architecture is proposed. This strategy avoids local decision-making unsuited to optimized overall power/energy management.

Power dissipated during scan testing is becoming increasingly important for today’s very complex sequential circuits. It is shown that the power dissipated during test mode operation is in general higher than the power dissipated during functional mode operation, the test mode average power may sometimes go upto 3x and the peak power may sometimes go upto 30x of normal mode operation. The power dissipated during the scan operation is primarily due to the switching activity that arises in scan cells during the shift and capture operation. The switching in scan cells propagates to the combinational block of the circuit during scan operation, which in turn creates many transition in the circuit and hence it causes higher dynamic power dissipation. The excessive average power dissipated during scan operation causes circuit damage due to higher temperature and the excessive peak power causes yield loss due to IR-drop and cross talk. The higher peak power also causes the thermal related issue if it last for sufficiently large number of cycles. Hence, to avoid all these issues it is very important to reduce the peak power during scan testing. Further, in case of multi-module SoC testing the reduction in peak power facilitates in reducing the test application time by scheduling many test sessions parallelly. In this dissertation we have addressed all the above stated issues. We have proposed three different techniques to deal with the excessive peak power dissipation problem during test. The first solution proposes an efficient graph theoretic methodology for test vector reordering to achieve minimum peak power supported by the given test vector set. Three graph theoretic problems are formulated and corresponding algorithms to solve the problems are proposed. The proposed methodology also minimizes average power for the given minimum peak power. Further, a lower bound on minimum achievable peak power for a given test set is defined. The results on several benchmarks show that the proposed methodology is able to reduce peak power significantly. To address the peak power problem during scan test-cycle (the cycle between launch and capture pulse) we have proposed a scan chain reordering technique. A new formulation for scan chain reordering as TSP (Traveling Sales Person) problem and a solution is proposed. The experimental results show that the proposed methodology is able to minimize considerable amount of peak power compared to the earlier proposals. The capture power (power dissipated during capture cycle) problem in testing multi chip module (MCM) is also addressed. We have proposed a methodology to schedule the test set to reduce capture power. The scheduling algorithm consist of reordering of test vector and insertion of idle cycle to prevent capture cycle coincidence of scheduled cores. The experimental results show the significant reduction in capture power without increase in test application time.

This study aims to examine the views of care managers in eldercare, on the mental health of the elderly, and how the care managers work to promote this mental health among those they care for. Thus, the study has a salutogenic perspective in that it focuses on what leads to mental health, rather than mental illness. The study was conducted as a qualitative study and is based on eight semi-structured interviews, all held with care managers in eldercare. The results of the interviews were analyzed thematically and compared to earlier research and Aaron Antonovsky's theory of SOC (sense of coherence). It turns out that care managers within eldercare give a clear picture of what they think causes mental illness among those they care for, with concrete suggestions on how they would wish to work preventively to promote elderly mental health - results that align with the theory of SOC (sense of coherence).

Bei der Entwickelung von System-on-Chip (SoC) Debuggern ist es leider hinreichend oft erforderlich den Debugger selbst auf mögliche Fehler zu untersuchen. Da alle ernstzunehmenden Debugger konstruktionsbedingt selbst ein eingebettetes System darstellen, erwächst die Notwendigkeit eine einfache und sicher kontrollierbare Diagnose-Hardware zu entwerfen, welche den Zugang zur Funktionsweise des Debuggers über seine Ausgänge erschließt. Derzeitig ist der Test Access Port (TAP nach IEEE 1149.1-Standard) für viele Integratoren die Grundlage für den Zugriff auf ihre instanzierte Hardware. Selbst in forschungsorientierten Multi- Core System-on-Chip Architekturen wie dem ARM11MP der Firma ARM wird dieses Verfahren noch immer eingesetzt. In unserem Beitrag möchten wir ein Spezialwerkzeug zur Analyse des TAPKommunikationsprotokolles vorstellen, welches den Einsatz teurer Analysetechnik (Logik- Analysatoren) unnötig werden lässt und darüber hinaus eine komfortable, weitergehende Unterstützung für Multi-Core-Systeme bietet. Aufbauend auf der Problematik der Abtastung und Erfassung der Signalzustände am TAP mittels FPGA wird auf die verschiedenen Visualisierungs- und Analyseaspekte der TAPProtokollphasen in einer Multi-Core-Prozessor-Zielsystemumgebung eingegangen. Die hier vorgestellte Lösung ist im Rahmen eines FuE-Verbundprojektes enstanden. Das Vorhaben wird im Rahmen der Technologieförderung mit Mitteln des Europäischen Fonds für regionale Entwicklung (EFRE) 2000-2006 und mit Mitteln des Freistaates Sachsen gefördert.

Hälsofrämjande arbete är en gren inom folkhälsoarbete. Arbetsplatsen är en arena som kan agera som stödjande miljö och där hälsofrämjande arbete kan bedrivas. Hälsofrämjande arbete på arbetsplatserna inom socialförvaltningen kan bedrivas med hjälp av teorin KASAM. Detta genom att skapa förutsättningar för första linjens chefer att uppleva hanterbarhet, begriplighet och meningsfullhet i att bedriva hälsofrämjande arbete. Syftet med studien är att beskriva vilka arbetsrelaterade möjligheter första linjens chefer inom socialförvaltningen upplever att de har för att kunna arbeta hälsofrämjande för medarbetarna. Studien har en kvalitativ ansats och riktar sig till målgruppen första linjens chefer inom socialförvaltningen. Data samlades in med semistrukturerade intervjuer och sex intervjupersoner valdes ut med ett målstyrt urval. Materialet analyserades med en manifest innehållsanalys. Studiens resultat belyser att målgruppen saknar väsentliga resurser som budget, tid, kunskap och stöd för att kunna bedriva hälsofrämjande arbete gentemot sina medarbetare. Resultatet visar även att det finns en skillnad i hur hälsofrämjande arbete definieras och att det behövs en ökad acceptans av att bedriva hälsofrämjande arbete. Slutsatsen är att hälsofrämjande arbete bedrivs genom arbetsmiljöarbete, delaktighet, närvaro och att ha en helhetssyn på medarbetarna. Vitala resurser för hälsofrämjande arbete saknas och förutsättningar samt acceptans behövs. / Health promotion work is a branch of public health work. The workplace is a developed arena that can act as a supportive environment where health promoting work can be conducted. Health promotion at workplaces within the Swedish social services administration can be conducted with the help of the theory sense of coherence. This by creating conditions for first-line managers to experience manageability, comprehensibility and meaningfulness in acting health promoting towards their employees. The purpose of the study is to describe the work-related opportunities first-line managers of the Swedish social services administration experience when acting health promoting towards their employees' work-related health. The study has a qualitative approach and is aimed at first-line managers in social services administration with a goal-oriented selection. Data was collected from six semi-structured interviews and was analyzed using a manifest content analysis. The results highlight a lack of significant resources such as budget, time and support to be able to conduct health-promoting work towards their employees. The results also show that there is a difference in how health-promoting work is defined and that increased acceptance is needed. The study concludes that health promotion work can be conducted through work environment management, participation and a holistic view. Vital resources are missing and acceptance for conducting health promotion work is needed.

The purpose of the study is to acquire knowledge and understanding of successful school development, with a focus on students' cognitive abilities. The survey focuses on the implementation of development work and its effects on the organization and students' development. The theoretical framework is based on special educational perspectives, salutogenic perspective and organizational theory. Two contiguous preschool class‑third grade schools are included in the study and primary data consists of interview responses from school staff. The study also includes questionnaire responses from guardians of children in third grade. However, the response rate from the guardians is insufficient for conclusions. The results show that school development changed the view of students' differences and needs. Furthermore, the schools have shifted their focus to group and organizational level, as well as to more promotional and preventive work. Fewer students are included in the student health team and the number of action plans has decreased. The development of the schools is characterized by a shift towards a more critical perspective and has been conducted through strengthened meaningfulness in the form of defined values, consensus in purpose and vision and collegial cooperation. The conditions that enable successful school development are characterized by a strong sense of coherence, in both leadership and conditions. Increased focus on the environment, as well as enhancement of comprehensibility, manageability and meaningfulness, are also factors that have benefited students' development. Factors that hinder school development can be traced to a compensatory and dilemma perspective, as well as to a lack of sense of coherence. Above all concerning attitudes among school staff and external demands placed on the school activities. Our conclusion is that both school development and students' cognitive abilities can be promoted through the application of a salutogenic perspective.
