▼ The expanding use of renewable and sustainable energy systems is at the forefront of the global effort to reduce CO2 emissions and mitigate climate change. Thermal energy storage has become a critical component of many of these new and innovative systems, and research in this field has expanded to meet their requirements. Water has been traditionally used as a storage medium because of its high heat capacity and low cost, but depending on the application, the storage volume requirements may be excessively large. Phase Change Materials (PCMs) offer an opportunity to reduce the storage volume through latent energy storage. However, energy storage in PCM presents new challenges, and careful design of thermal storage is required to realize the benefits. The design of PCM storage must consider the system operation, operating temperature range, PCM properties, encapsulation, and the heat transfer fluid. In the current state-of-the-art literature, there is no standard method for designing PCM thermal storage based on system requirements. The objective of this thesis is to deliver a methodology to assess the feasibility of using PCM for thermal energy storage in place of water. This is done by identifying which applications benefit from PCM, comparing the analytical and numerical performance of water-only to hybrid water-PCM storage, and developing a method to size PCM containment to achieve theoretical performance when PCM is beneficial. This research study develops analytical solutions for sizing PCM thermal energy storage based on system boundary conditions. These boundary conditions consist of the system itself (e.g. heat pump, absorption chiller), the energy source into the system, and the required load from the system (e.g. a building). The PCM is incorporated into a water tank such that the water acts as both a heat transfer fluid and an energy store. Analytical predictions of the total energy storage capacity in this hybrid water-PCM thermal storage unit are coupled to analytical predictions of the rate of melting and solidification to appropriately determine the required volume and encapsulation thickness of PCM thermal storage based on the system requirements. The results are verified against full-system numerical simulations based on case studies of solar absorption cooling and heat-pump heating. It is shown in this study that the total required volume of storage is a function of the temperature differential of the system, and the total mismatch in time between when energy is available and when it is required. A mathematical formulation is proposed which quantifies the required storage volume based on the temperature differential, the source and load profiles, and the percentage of PCM in the hybrid water-PCM storage unit. Furthermore, the rate of melting and solidification of the thermal storage is coupled to the overall storage size and required time for charging, and a mathematical formulation is proposed which solves for the PCM encapsulation thickness. The method assumes a conservative… Advisors/Committee Members: Cotton, James, Lightstone, Marilyn, Mechanical Engineering.

▼ Building-integrated Concentrator Photovoltaic (BICPV) technology produces noiseless and pollution free electricity at the point of use. With a potential to contribute immensely to the increasing global need for a sustainable and low carbon energy, the primary challenges such as thermal management of the panels are overwhelming. Although significant progress has been made in the solar cell efficiency increase, the concentrator photovoltaic industry has still to go a long way before it becomes competitive and economically viable. Experiencing great losses in their electrical efficiencies at high temperatures that may eventually lead to permanent degradation over time, affects the market potential severely. With a global PV installed capacity of 303 GW, a nominal 10 °C decrease in their average temperatures could theoretically lead to a 5 % electricity efficiency improvement resulting in 15 GW increase in electricity production worldwide. However, due to a gap in the research knowledge concerning the effectiveness of the available passive thermal regulation techniques both individually and working in tandem, this lucrative potential is yet to be realised. The work presented in this thesis has been focussed on incremental performance improvement of BICPV by developing innovative solutions for passive cooling of the low concentrator based BICPV. Passive cooling approaches are selected as they are generally simpler, more cost-effective and considered more reliable than active cooling. Phase Change Materials (PCM) have been considered as the primary means to achieve this. The design, fabrication and the characterisation of four different types of BIPCV-PCM assemblies are described. The experimental investigations were conducted indoors under the standard test conditions. In general, for all the fabricated and assembled BICPV-PCM systems, the electrical power output showed an increase of 2 %-17 % with the use of PCM depending on the PCM type and irradiance. The occurrence of hot spots due to thermal disequilibrium in the PV has been a cause of high degradation rates for the modules. With the use of PCM, a more uniform temperature within the module could be realised, which has the potential to extend the lifetime of the BICPV in the long-term. Consequentially, this may minimise the intensive energy required for the production of the PV cells and mitigate the associated environmental impacts. Following a parallel secondary approach to the challenge, the design of a micro-finned back plate integrated with a PCM containment has been proposed. This containment was 3D printed to save manufacturing costs and time and for reducing the PCM leakage. An organic PCM dispersed with high thermal conductivity nanomaterial was successfully tested. The cost-benefit analysis indicated that the cost per degree temperature reduction (£/°C) with the sole use of micro-fins was the highest at 1.54, followed by micro-fins + PCM at 0.23 and micro-fins + n-PCM at 0.19. The proposed use of PCM and application of micro-finned surfaces for BICPV heat…

May 25, 2011, Reuters’ headline read: "New York State is prepared for summerelectricity demand". The NY operator forecasts for next summer a peak of 33GW, close to therecord ever reached. With soaring cooling demands, the electricity peak load represents a substantialconcern to the energy system. In the goal of peak shaving, research on alternative solutions based onThermal Energy Storage (TES), for both cooling and heating applications, has been largely performed.This thesis addresses thermal comfort applications with use of active free cooling through implementationof latent heat based TES. Active free cooling is based on the use of the freshness of a source, the outsideair for example, to cool down buildings. This work conceptualizes the implementation of TES basedcooling system with use of Phase Change Material in an in-house-built model. The principle of PhaseChange Material, or Latent Heat TES (LHTES), lies on latent energy which is the energy required for thematerial to change phase. In order to properly size this cooling system, a multi-objective optimization isadopted. This optimization, based on minimization of multi-objective functions, led to optimal designconfigurations. In parallel, the electrical consumption of the system and the volume uptake of the systemwere also considered. Through the obtained optimization studies, we identified non-linearinterdependency between the two objective functions: the cost of the system and the acceptable remainingcooling needs. By remaining cooling needs, we mean the cooling needs that the system cannot meet. As amatter of fact, sizing the system according to these cooling needs would imply a very high cost. It wasfound that for a certain amount of remaining cooling needs, the PCM-based cooling system reveals to bean interesting solution compared to conventional air conditioning in terms of electrical consumption andoverall system cost.

Récemment, la course à la miniaturisation a vue sa progression ralentir à cause des défis technologiques qu’elle implique. Parmi ces obstacles, on trouve l’impact croissant de la variabilité local et process émanant de la complexité croissante du processus de fabrication et de la miniaturisation, en plus de la difficulté à réduire la longueur du canal. Afin de relever ces défis, de nouvelles architectures, très différentes de celle traditionnelle (bulk), ont été proposées. Cependant ces nouvelles architectures demandent plus d’efforts pour être industrialisées. L’augmentation de la complexité et du temps de développement requièrent de plus gros investissements financier. De fait il existe un besoin réel d’améliorer le développement et l’optimisation des dispositifs. Ce travail donne quelques pistes dans le but d’atteindre ces objectifs. L’idée, pour répondre au problème, est de réduire le nombre d’essai nécessaire pour trouver le processus de fabrication optimal. Le processus optimal est celui qui conduit à un dispositif dont les performances et leur dispersion atteignent les objectifs prédéfinis. L’idée développée dans cette thèse est de combiner l’outil TCAD et les modèles compacts dans le but de construire et calibrer ce que l’on appelle un PCM (Process Compact Model). Un PCM est un modèle analytique qui établit les liens entre les paramètres process et électriques du MOSFET. Il tire à la fois les bénéfices de la TCAD (puisqu’il relie directement les paramètres process aux paramètres électriques) et du modèle compact (puisque le modèle est analytique et donc rapide à calculer). Un PCM suffisamment prédictif et robuste peut être utilisé pour optimiser les performances et la variabilité globale du transistor grâce à un algorithme d’optimisation approprié. Cette approche est différente des méthodes de développement classiques qui font largement appel à l’expertise scientifique et à des essais successifs dans le but d’améliorer le dispositif. En effet cette approche apporte un cadre mathématique déterministe et robuste au problème.Le concept a été développé, testé et appliqué aux transistors 28 et 14 nm FD-SOI ainsi qu’aux simulations TCAD. Les résultats sont exposés ainsi que les recommandations nécessaires pour implémenter la technique à échelle industrielle. Certaines perspectives et applications sont de même suggérées.

Recently, the race for miniaturization has seen its growth slow because of technological challenges it entails. These barriers include the increasing impact of the local variability and processes from the increasing complexity of the manufacturing process and miniaturization, in addition to the difficult of reducing the channel length. To address these challenges, new architectures, very different from the traditional one (bulk), have been proposed. However these new architectures require more effort to be industrialized. Increasing complexity and development time require larger financial investments. In fact there is a real need to improve the development and optimization of devices. This work…

▼ Power dissipation and memory bandwidth are significant performance bottlenecks in virtually all computer systems. Associative computing with ternary content addressable memories (TCAM) holds the potential to address both problems in a wide range of data intensive workloads. Power dissipation is reduced by eliminating instruction processing and data movement overheads present in a purely RAM based system. Bandwidth demand is lowered by processing data directly on the TCAM chip, thereby decreasing -chip traffic. Unfortunately, existing SRAM-based TCAM cells are over 90 larger than a DRAM cell at the same technology node, which limits the capacity of commercially available TCAMs to a few megabytes. </br> This dissertation first examines the integration of gigascale TCAM systems based on resistive memories within a general purpose computing platform. TCAM density is improved by novel, resistive memory cells that exploit phase change and spin-toque transfer magnetoresistive RAM technologies. TCAM chips are organized into a DDR3-compatible DIMM, and are accessed through a software library with zero modifications to the processor or the motherboard. Leveraging associative lookups by the memory circuits and a set of integrated, programmable microcontrollers that execute user-denied kernels on the search results, the proposed TCAM systems achieve average speedups of 4-4.2 and average energy reductions of 6.5-8 as compared to a conventional RAM based system. </br> The dissertation second presents the case for a database processing unit (DPU) that significantly improves the energy efficiency in big data analytics. The DPU augments a general-purpose processor with 1) an STT-MRAM based scratchpad memory that implements a CAM cell with a 2.45 higher density than an SRAM cell, and 2) an enhanced DMA unit that facilitates the transportation of data between the CAM and memory subsystem. By mapping the relational database operators to the CAM circuits, columns of data are processed directly on the CAM chip in a vectorized manner. This eschews streaming the entire data set in and out of the processor pipeline, and significantly reduces the performance and energy overheads caused by the data movement.

Dissertação para obtenção do Grau Mestre em Engenharia Civil – Perfil de Construção

As argamassas de terra foram muito utilizadas no passado em Portugal para rebocos interiores e para o assentamento de algumas alvenarias revestidas. Durante algumas décadas a sua utilização cessou e o conhecimento empírico inerente à sua aplicação praticamente perdeu-se. As qualidades ecológicas das argamassas de terra já são bem conhecidas. A eficiência técnica destas argamassas quando aplicadas em sistemas de reboco e, particularmente, as suas características, necessitam de ser avaliadas através de procedimentos normalizados, de modo a poderem ser comparadas entre diferentes argamassas à base de terra e com os requisitos de argamassas de reboco. O interesse por este tipo de argamassas tem aumentado a nível científico e da indústria. A prova desse interesse é o facto de a Alemanha ter publicado em 2013 uma norma DIN que estabelece os termos, definições, requisitos e métodos de ensaio de argamassas de terra sem estabilização química por outro ligante para rebocos. A presente dissertação tem como por objetivo estabelecer procedimentos experimentais e carac-terizar várias argamassas de terra, umas pré-doseadas outras formuladas em laboratório com diferentes areias e adições (fibras e material de mudança de fase), para que seja possível determinar as propriedades, vantagens e desvantagens em relação a outros tipos de argamassas. A principal conclusão é que as argamassas de terra, que só podem ser utilizadas no exterior efici-entemente protegidas, constituem sistemas de reboco interior eco-eficientes. Este tipo de argamassas, com baixa energia incorporada em termos de matérias-primas utilizadas, apresentam características mecânicas e físicas que cumprem genericamente os requisitos definidos para rebocos interiores. A higroscopicidade destas argamassas pode ser salientada como uma das vantagens; tendo em conta que têm a capacidade de adsorver e libertar grandes quantidades de vapor de água, podem contribuir para a melhoria do conforto interior dos espaços. Quando incorporado um material de mudança de fase nas argamassas de terra, estas apresentam um decréscimo ao nível da sua resistência.

▼ All energy, wind, water, biofuel and fossil fuel besides nuclear- and tide power originates from the sun. It’s very hard to take full advantage of the huge amount of energy hitting the earth each day from the sun. The suns highest radiation appears often when the energy need reaches its lowest. That’s why it’s very important to be able to store energy over time when the sun doesn’t shine. A large part of energy storage is thermal energy storage, which can either be done sensible, latent or chemical. Another possible thermal storage is a combination of sensible and latent. This exam was aiming to investigate different types of energy storage methods available on the market and a much more detailed analysis for different storage methods with phase change materials (PCM). A new method was designed for a new storage tank suitable for Absolicon Solar Collector AB and their energy park in the city of Härnösand. The methods for this exam were to create a theoretical storage tank suitable to Absolicons Energy Park with some simple calculations. The criteria for the storage tank was to create a storage tank that could provide the district heat in Härnösand with 160 degrees pressurized water and create 160 degrees steam to the industry. The dimensions of the storage tank where chosen by the conditions in Härnösand and from the specific data of Härnösands district heat and from Absolicons new solar collectors. The work temperature of the system were set to 160 degrees which meant that the storage tank would be able to work in those conditions with high temperature. A suitable phase change material and methods for encapsulation of the phase change material suitable for this system was to be found. Small tests were made with a new type of encapsulation for phase change materials in higher temperature. Simple calculations of two types of storage tanks were made. The first storage tank was made with a PCM from PCM products named A164. This PCM was encapsulated with special bags that could handle temperature up to 200 degrees with surrounding rapeseed oil and a copper loop that handled the heat transfer. The second thank was made with the same PCM and encapsulation but with water glycol surrounding the PCM and two types of heat exchangers for the heat transfer. The results from the first tank were that it didn’t work with the district heat. Because a wrong calculation with the schematic of the system made it impossible to connect into the district heat of Härnösand. The only good thing was that it didn’t need to be pressurized because of the rapeseed oil but the bad heat transfer between oil and water made a pressurized tank of water more profitable. The results from the second tank showed that it could produce 160 °C to the district heat for 2 h and 7 minutes. The schematic connection worked and the tank would in the near future be able to connect into the district heat. The result for the encapsulation showed that the bags were able to stand temperatures up to 190 degrees for a short period of time.

▼ The increase in peak electricity demand in recent years has stressed the importance of peak electricity demand shifting technologies. Phase Change Materials (PCMs) have a potential to improve the building envelope by increasing the thermal mass as well as contribute to a significant peak shift in whole building power demand. Therefore, special attention is given to properly capture the thermal behavior of PCMs in advanced building energy modeling software. Design of effective PCM thermal storage systems requires accurate energy modeling. There are analytical and numerical models developed during last few decades for this purpose, many have not been fully validated. Based on the current status of literature, the study identifies the limitations and drawbacks of existing methods. A parametric study is conducted to identify the optimum PCM thermo-physical properties, PCM locations in building envelope, under forced convection and a 5 hour pre-cooling strategy. Furthermore, an improved advanced numerical building envelope model is created in MATLAB to simulate the PCM performance in building envelope and an experimental apparatus is constructed to obtain useful experimental data for PCM included wall assemblies for validation purposes. This thesis also uses two datasets from laboratory studies of shape-stabilized and field studies nano-encapsulated PCMs to validate and compare PCM modelling algorithms of 6 modules in 5 building energy modelling software. Finally, two macroencapsulated PCMs (Bio based PCM and hydrate salts) are tested using the experimental apparatus to obtain data for validation purposes. To approximate the heat transfer through a wall assembly with PCM pouches several techniques are investigated that can capture 3D heat transfer characteristics. Method with the highest agreement is used to validate and compare the developed MATLAB algorithm and different building energy modelling software.

Att leva med diabetes kan vara krångligt då det hela tiden krävs planering av aktiviteter, måltider och medicinering. Sjukdomen behandlas framförallt med insulin som kan förekomma i pump, sprutor och injektionspennor. Det vanligaste sättet att injicera insulin är med pennor, och antalet pennanvändare ökar årligen. Insulin har stränga förvaringskrav och är känsligt mot hög värme, starkt ljus, skakningar och frysning. De personer som lever i länder där temperaturen över- eller understiger säkert förvarings-intervall har ett behov av att skydda sin medicin, men också resande till utsatta platser drabbas. Andra mediciner och hormon har förvaringskrav inom samma ramar som insulinet och intresse och behov finns för en förvaringslösning som kan säkerställa trygg förvaring av läkemedel som används dagligen. För att säkerställa en korrekt temperatur i en framtida produkt undersöks teorier inom värmeöverföring och kunskaper om isolerande material i kombination med Climators ClimSel™-kylelement. Det finns ett flertal konkurrerande lösningar på marknaden, dock har de vissa negativa egenskaper som medför att det skulle kunna finnas utrymme för ytterligare produkter om de får tillräckligt bra prestanda. Enligt förstudien finns behov av att skydda hormonerna mot både kyla och värme. Produkten utvecklas för att tillgodose behovet hos vardagsanvändare av hormoner för att maximera marknadspotentialen. En stor del av arbetet koncentreras på temperaturtester där olika kylelement, isoleringsmaterial och geometrier testas och utvärderas för att utveckla den optimala systemdesignen. Förvaringslösningens detaljdesign utvecklas med olika kreativitetsmetoder med fokus på användbarhet, target cost och optimal prestanda. Resultatet påvisar att förvaringslösningens prestanda blir för låg vid en geometri och volym som anses acceptabel hos användarna, vilket medför att det finns svårigheter i att uppnå en relevant marknadspotential.

Living with diabetes can be difficult due to the required extra planning of activities, meals and medica-tion. The disease is treated primarily with insulin, which can be delivered by pump, syringes or pens. The most common way to inject insulin is by pen, and the number of pen users is increasing annually. Insulin has strict storage requirements and is sensitive to heat, strong light, vibrations and freezing. Users in countries where the temperature goes above or below the safe storage interval have a need to protect their medicine, as well as users travelling to affected places. Other drugs and hormones have storage requirements within the same framework as insulin, which means that there is an additional interest and need for a storage solution that can ensure safe storage of medicine that is used daily. To ensure the correct temperature in a future product, this project will examine theories of heat transfer and knowledge of insulating materials in combination with a range of ClimSel™-cooling elements produced by Climator Sweden AB. There are several competing solutions currently…

▼ In latent heat storage, internal heat transfer enhancement techniques such as fins have to be used because of the low heat conductivity of the phase change material (PCM). During the phase change in a PCM storage system the solid-liquid interface moves away from the heat transfer surface and the surface heat flux decreases due to the increasing thermal resistance of the molten or solidified medium. Internal heat transfer enhancement is essential, especially in a solidification process where the main heat transfer mode is conduction. The objective of this study was to develop an analytical model which predicts the solid-liquid interface location and temperature distribution of the fin in melting and especially, in solidification processes with a constant end wall temperature in a finned two-dimensional PCM storage. Heat transfer during the melting and solidification processes in a finned PCM storage was also studied numerically and experimentally. The objective of the experimental work was to evaluate different numerical methods in order to find a reliable numerical method for the comparison of several PCM storage structures. The results of the derived analytical model were compared to numerical results calculated with the FEMLAB multiphysics simulation tool and Digital Fortran 5.0. The simplified analytical equations were solved with FEMLAB in order to find out the accuracy of the analytical solution. The two-dimensional heat transfer problem was also solved numerically by means of the effective heat capacity method and enthalpy method, using FEMLAB and Digital Fortran. The two-dimensional results were compared to simplified one-dimensional results in order to find out the accuracy of the simplified analytical model. The results of the experimental work were compared to the numerical results calculated with FEMLAB, using the effective heat capacity method and enthalpy method, in order to find out the accuracy of different numerical methods. A simplified analytical model based on a linear, transient, thin-fin equation was introduced which predicts the solid-liquid interface location and temperature distribution of the fin in the melting process with a constant imposed end wall temperature for the melting process in a semi-infinite PCM storage and for the solidification process in a finite PCM storage with internal fins. The results show that the analytical models give a satisfactory estimate of fin temperature and the solid-liquid interface. It was noticed that the assumptions made in simplifying the two-dimensional heat transfer problem into a one-dimensional form affected the accuracy to a greater extent than the assumptions made when solving the one-dimensional equations analytically. The results showed that the effective heat capacity method with a narrow temperature range, dT = 2 °C, was the most precise numerical method when numerical results were compared to experimental results in a finned paraffin PCM storage. The FEMLAB program was very suitable for solving different kinds of phase change problems in… Advisors/Committee Members: Helsinki University of Technology, Department of Mechanical Engineering, Laboratory of Heating, Ventilating and Air Conditioning.

A l'heure actuelle, les nouvelles contraintes de la réglementation thermique en vigueur ne cessent de s'adapter au contexte économique global pour lequel la recherche d'une efficacité énergétique dans le bâtiment est devenue incontournable. Pour répondre à ces défis, des Matériaux intelligents à Changement de Phase (MCP) ont fait leur apparition sur le marché de la construction. Grâce à leur capacité de stockage de l'énergie, les MCP sont de plus en plus associés aux matériaux de construction classiques (béton, plâtre, etc.) afin d'améliorer leur inertie thermique et apporter un meilleur confort aux usagers. Pour ce faire, les propriétés thermophysiques intrinsèques aux MCP doivent être suffisamment maitrisées afin de pouvoir contrôler les propriétés du produit composite final. Dans ce contexte, cette thèse est une contribution ayant pour objectif de développer des méthodologies spécifiques pour une meilleure caractérisation des MCP et des béton-MCP. Une panoplie d'approches expérimentales a été présentée pour l'identification des propriétés thermophysiques des MCP et pour identifier l'effet d'incorporation et de l'endommagement de ces matériaux sur les propriétés thermiques et mécaniques de béton. Plusieurs modèles d'homogénéisation ont été utilisés afin de prédire le comportement thermique des bétons-MCP en utilisant les propriétés thermiques moyennées obtenues expérimentalement. Une étude probabiliste paramétrique a été menée afin de prendre en compte les incertitudes liées à la dispersion aléatoire des mesures expérimentales de propriétés thermiques du béton-MCP. Les résultats issus des essais expérimentaux ont été intégrés dans le cadre d'une étude numérique par la Méthode des Volumes finis (MVF) afin d'étudier le mécanisme de transfert de chaleur à travers une paroi en béton-MCP

The thermal policies have been kept to fit the new economic in a global context particularly in terms of buildings energy efficiency. To meet these challenges, different technologies have been used such as the Phase Change Materials (PCMs) which have the ability to store and release energy. PCMs are generally used with conventional building materials in order to improve their thermal inertia and provide better comfort to users. To enhance the properties of the final composite, the PCMs thermo-physical properties must be sufficiently controlled. In this context, this thesis is a contribution aimed to develop specific methodologies for better characterization of PCM and PCM-concrete. Different experimental approaches will be presented for the identification of PCMs thermophysical properties and to identify the effect of the incorporation and the damage of these materials on the thermal and mechanical properties of concrete. A multiscale modelling considering the average of experimental thermal properties was applied to predict the thermal behaviour of PCMs-concrete. A probabilistic study of experimental uncertainties will be also conducted to assess the level of confidence of the impact of PCM on the thermodynamic properties of…

▼ Les Mémoires ont de plus en plus importance à l'époque actuelle, et sont fondamentales pour la définition de tous les systèmes électroniques avec lesquels nous entrons en contact dans notre vie quotidienne. Les mémoires non-volatiles (NVM), représentées par la technologie Flash, ont pu suivre jusqu'à présent l'effort à la miniaturisation pour satisfaire la demande croissante de densité de mémoire exigée par le marché. Cependant, la réduction de la taille du dispositif de mémoire est de plus en plus difficile et la complexité technologique demandé a augmenté le coût par octet. Dans ce contexte, les technologies de mémoire innovantes deviennent non seulement une alternative, mais la seule solution possible pour fournir une densité plus élevée à moindre coût, une meilleure fonctionnalité et une faible consommation d'énergie. Les Mémoires à Changement de Phase (PCM) sont considérées comme la solution de pointe pour la future génération de mémoires non-volatiles, grâce à leur non-volatilité , scalabilité, "bit-alterability", grande vitesse de lecture et d'écriture, et cyclabilité élevée. Néanmoins, certains problèmes de fiabilité restent à surmonter afin de rendre cette technologie un remplacement valable de la technologie Flash dans toutes les applications. Plus en détail, la conservation des données à haute température, est l'une des principales exigences des applications embarquées industrielles et automobiles. Cette thèse se concentre sur l'étude des mémoires à changement de phase pour des applications embarquées, dans le but d'optimiser le dispositif de mémoire et enfin de proposer des solutions pour surmonter les principaux obstacles de cette technologie, en abordant notamment les applications automobiles. Nous avons conçu, fabriqué et testé des dispositifs PCM basés sur des structures reconnues et innovantes, en analysant leurs avantages et inconvénients, et en évaluant l'impact de la réduction de la taille. Notre analyse de fiabilité a conduit au développement d'un système de caractérisation dédié à caractériser nos cellules PCM avec des impulsions de l'ordre de la nanoseconde, et à la mise en oeuvre d'un outil de simulation basé sur un solveur thermoélectrique et sur l'approche numérique "Level Set", pour comprendre les différentes mécanismes qui ont lieu dans nos cellules pendant les opérations de programmation. Afin de répondre aux spécifications du marché des mémoires non-volatiles embarquées, nous avons conçu le matériau à changement de phase intégré dans le dispositif PCM avec deux principales approches: la variation de la stoechiométrie et l'ajout de dopants. Nous avons démontré et expliqué comment la rétention des données dans les dispositifs PCM à base de GeTe peut être améliorée avec l'augmentation de la concentration de Te, et comment les inclusions de SiO2 peuvent réduire les défauts causés par la tension de lecture à températures de fonctionnement élevées. En outre, nous avons présenté les avantages sur la réduction de la puissance de programmation du dopage de carbone dans les dispositifs à base de… Advisors/Committee Members: Ghibaudo, Gérard (thesis director).

Cette étude se propose de créer un outil de mesure de l'attachement, sur la base d'une complétion d'histoires à partir d'un support photographique : le CHEAP (Complétions d'Histoires pour Évaluation de l'Attachement avec Photos). Ce test, adapté aux personnes porteuses de déficience intellectuelle, requiert peu de capacités d'abstraction et sa durée de passation est courte. Un modèle de réponse à l'item (PCM ; Wright & Masters, 1982) a de plus permis d'obtenir une procédure de cotation simple d'utilisation et rapide. Cet instrument possède également de bonnes propriétés sychométriques. Dans un deuxième temps, le CHEAP a permis de conclure que les adolescents porteurs de Trisomie 21(N=26) et les enfants contrôles (N=27) présenteraient des représentations d'attachement moins sécures que les adolescents témoins (N=64). Par ailleurs, l'étude a permis de mettre en évidence que les adolescents porteurs de T21 ontdavantage de difficultés aux épreuves d'efficience intellectuelle et de vocabulaire et que le nombre de comportements difficiles rapporté par leurs parents est plus élevé que pour les autres groupes (N=96 pour les mères, N=61 pour les pères, pour les trois groupes réunis). En revanche leurs parents ressentent autant d'émotions positives envers leurenfant que ceux des autres groupes, ne sont pas plus stressés que les parents d'adolescents contrôles et présentent les mêmes patterns d'attachement que dans les autres groupes. Ensuite, une analyse de la covariance a montré qu'un des facteurs impliqué dans l'insécurité d'attachement est l'efficience intellectuelle. D'autre part, plus la séparation d'avec les parents à la naissance a été longue, plus grande est la sécurité d'attachement, ce qui témoigne d'une certaine forme de résilience. Finalement, le Reaction to Diagnosis Interview (Marvin & Pianta, 1996) a été utilisé pour la première fois en français lors d'entretiens avec les parents des adolescents porteurs de Trisomie 21, suite à quoi des pistes concernant l'annonce du diagnostic ont été proposées.

This study aims at creating a new tool for assessment of attachment based on a story completion task and photographs: the CHEAP (story completion for assessment of attachment with photos). This test is designed for people with intellectual disabilities, as it requires few abstraction abilities and little time. A simple and fast scoring procedure was made available with the help of an item response theory model (PCM; Wright & Masters, 1982). This instrument also showed goodpsychometric properties. As a second step, using the CHEAP led to the conclusion that teenagers living with Down dyndrome (N=26) and children from the control group (N=27) were more at risk of having insecure representations of attachment than control adolescents (N=64). This study also demonstrated that teenagers with Down Syndrome had more difficulties when they were taking intellectual ability and vocabulary tests and that the number of challenging behaviours reported by their parents was higher than in other groups (N=96 for mothers, N=61…

Le cerveau humain est composé d’un grand nombre de réseaux neuraux interconnectés, dont les neurones et les synapses en sont les briques constitutives. Caractérisé par une faible consommation de puissance, de quelques Watts seulement, le cerveau humain est capable d’accomplir des tâches qui sont inaccessibles aux systèmes de calcul actuels, basés sur une architecture de type Von Neumann. La conception de systèmes neuromorphiques vise à réaliser une nouvelle génération de systèmes de calcul qui ne soit pas de type Von Neumann. L’utilisation de mémoire non-volatile innovantes en tant que synapses artificielles, pour application aux systèmes neuromorphiques, est donc étudiée dans cette thèse. Deux types de technologies de mémoires sont examinés : les mémoires à changement de phase (Phase-Change Memory, PCM) et les mémoires résistives à base d’oxyde (Oxide-based resistive Random Access Memory, OxRAM). L’utilisation des dispositifs PCM en tant que synapses de type binaire et probabiliste est étudiée pour l’extraction de motifs visuels complexes, en évaluant l’impact des conditions de programmation sur la consommation de puissance au niveau du système. Une nouvelle stratégie de programmation, qui permet de réduire l’impact du problème de la dérive de la résistance des dispositifs PCM est ensuite proposée. Il est démontré qu’en utilisant des dispositifs de tailles réduites, il est possible de diminuer la consommation énergétique du système. La variabilité des dispositifs OxRAM est ensuite évaluée expérimentalement par caractérisation électrique, en utilisant des méthodes statistiques, à la fois sur des dispositifs isolés et dans une matrice complète de mémoire. Un modèle qui permets de reproduire la variabilité depuis le niveau faiblement résistif jusqu’au niveau hautement résistif est ainsi développé. Une architecture de réseau de neurones de type convolutionnel est ensuite proposée sur la base de ces travaux éxperimentaux. La tolérance du circuit neuromorphique à la variabilité des OxRAM est enfin démontrée grâce à des tâches de reconnaissance de motifs visuels complexes, comme par exemple des caractères manuscrits ou des panneaux de signalisations routières.

The human brain is made of a large number of interconnected neural networks which are composed of neurons and synapses. With a low power consumption of only few Watts, the human brain is able to perform computational tasks that are out of reach for today’s computers, which are based on the Von Neumann architecture. Neuromorphic hardware design, taking inspiration from the human brain, aims to implement the next generation, non-Von Neumann computing systems. In this thesis, emerging non-volatile memory devices, specifically Phase-Change Memory (PCM) and Oxide-based resistive memory (OxRAM) devices, are studied as artificial synapses in neuromorphic systems. The use of PCM devices as binary probabilistic synapses is studied for complex visual pattern extraction applications, evaluating the impact of the PCM programming conditions on the system-level power…

La mémoire à changement de phase (ou PCM) est considérée actuellement comme la plus mature des technologies émergentes susceptibles de pallier les limitations de la mémoire Flash-NOR pour le futur des applications embarquées. Afin de permettre la conception de circuits à base de PCM, l’utilisation d’outils tels que la simulation SPICE est nécessaire, impliquant le besoin de modèles compacts de PCM. Ces modèles doivent être rapides, continus, et précis ; à ce jour aucun modèle de la littérature ne remplit l’ensemble de ces exigences.L’objectif de cette thèse est de proposer un nouveau modèle compact de PCM, permettant la conception de circuits à base de PCM. Le modèle que nous avons développé est entièrement continu, validé sur une large gamme de tension, courant, temps et température. Construit à partir de connaissances physiques sur le fonctionnement du dispositif, il utilise un emballement thermique dans le mécanisme de Poole-Frenkel pour modéliser le seuil de commutation de la phase amorphe. L’introduction d’une variable de fraction fondue, dépendante uniquement de la température, ainsi que d’une vitesse de cristallisation dépendante de la fraction amorphe, permet la bonne modélisation de l’ensemble des dynamiques temporelles de changement d’état. De plus, une méthodologie d’extraction optimisée de la carte modèle est proposée à la suite de la validation du modèle, reposant sur une étude de sensibilité des paramètres de la carte modèle et un ensemble simple de caractérisations électriques, autorisant l’adaptation du modèle à chaque variation des procédés de fabrication pour garantir l’utilité du modèle à toutes les étapes du développement des technologies PCM

Phase-change memory (PCM) is arguably the most mature emerging nonvolatile memory, foreseen for the replacement of the mainstream NOR-Flash memory for the future embedded applications. To allow the design of new PCM-based products, SPICE simulations, thus compact models, are needed. Those models need to be fast, robust and accurate; nowadays, no published model is able to fill all these requirements.The goal of this thesis is to propose a new compact model of PCM, enabling PCM-based circuit design. The model that we have developed is entirely continuous, and is validated on a wide range of voltage, current, time and temperature. Built on physical insights of the device, a thermal runaway in the Poole-Frenkel mechanism is used to model the threshold switching of the amorphous phase. Besides, the introduction of a new variable representing the melted fraction, depending only on the internal temperature, along with a crystallization speed depending on the amorphous fraction, allow the accurate modeling of all the temporal dynamics of the phase transitions. Moreover, an optimized model card extraction flow is proposed following the model validation, relying on a sensibility analysis of the model card parameters and a simple set of electrical characterizations. It enables the adjustment of the model to any process variation, and thus ensures its accuracy for…
