Full textBuildings are increasingly equipped with dedicated automation networks, aiming to reduce the energy consumption and to optimize the comfort. On the other hand, we see the arrival of sensors and actuators related to the Internet of Things, which can naturally connect to IP networks. Due to constraints imposed by the obsolescence or physical properties of buildings, it is not uncommon that different technologies have to coexist. These networks operate with different models and protocols, making the development of global automation systems difficult. Traditional models of distributed systems are not adapted to the context of sensor networks. The paradigm of the Web of Things is resource-based and strives to standardize the application layer of different objects using Web technologies, primarily HTTP and REST. In this thesis, we use the Web of Things to create a framework dedicated to smart buildings, allowing developers to develop composite applications without knowledge of the underlying technologies. By relying on Web technologies, we can provide seamless service while reusing the available resources within the network (sensors and actuators), forming a self-managed cloud. In order to equip the buildings with a higher-level intelligence, machine learning, often reserved for experts, is made accessible through Web interfaces hiding the complexity of the process

Full textMatrices, as natural representation of linear mappings in finite dimension, play a crucial role in signal processing and machine learning. Multiplying a vector by a full rank matrix a priori costs of the order of the number of non-zero entries in the matrix, in terms of arithmetic operations. However, matrices exist that can be applied much faster, this property being crucial to the success of certain linear transformations, such as the Fourier transform or the wavelet transform. What is the property that allows these matrices to be applied rapidly ? Is it easy to verify ? Can weapproximate matrices with ones having this property ? Can we estimate matrices having this property ? This thesis investigates these questions, exploring applications such as learning dictionaries with efficient implementations, accelerating the resolution of inverse problems or Fast Fourier Transform on graphs

Full textNowadays, companies’ competitiveness depends on their ability to innovate products and processes, keeping in mind that a better quality of life is given by the sustainable management of resources and a lower impact on society and the environment. This involves a deep change towards more sustainable production and consumption systems along with a change in culture and life style, i.e. a transition towards a green economy. Eco-innovation is the main instrument of green economy and, consequently, of sustainable development. In particular, thanks to the introduction of an environmentally friendly system, companies can achieve a reduction of their carbon footprint that can be observed along the entire life cycle of their products or processes. The eco-innovation can consist in the development of manufacturing technologies more sustainable as well as in the development of new Eco-friendly and lightweight materials, especially in the automotive and aeronautical sectors, where the environmental benefit is greater with the reduction of carbon emission, coupled with the savings in fuel. In light of this, the overall purpose of the work developed in this thesis is to analyze the environmental sustainability concept in the manufacturing processes through a Multiple-Perspective Approach.

Full textThe field of parallel supercomputing has been changing rapidly inrecent years. The reduction of costs of the parts necessary to buildmachines with multicore CPUs and accelerators such as GPUs are ofparticular interest to us. This scenario allowed for the expansion oflarge parallel systems, with machines far apart from each other,sometimes even located on different continents. Thus, the crucialproblem is how to use these resources efficiently.In this work, we first consider the efficient allocation of taskssuitable for CPUs and GPUs in heterogeneous platforms. To that end, weimplement a tool called SWDUAL, which executes the Smith-Watermanalgorithm simultaneously on CPUs and GPUs, choosing which tasks aremore suited to one or another. Experiments show that SWDUAL givesbetter results when compared to similar approaches available in theliterature.Second, we study a new online method for scheduling independent tasksof different sizes on processors. We propose a new technique thatoptimizes the stretch metric by detecting when a reasonable amount ofsmall jobs is waiting while a big job executes. Then, the big job isredirected to separate set of machines, dedicated to running big jobsthat have been redirected. We present experiment results that show thatour method outperforms the standard policy and in many cases approachesthe performance of the preemptive policy, which can be considered as alower bound.Next, we present our study on constraints applied to the Backfillingalgorithm in combination with the FCFS policy: Contiguity, which is aconstraint that tries to keep jobs close together and reducefragmentation during the schedule, and Basic Locality, that aims tokeep jobs as much as possible inside groups of processors calledclusters. Experiment results show that the benefits of using theseconstrains outweigh the possible decrease in the number of backfilledjobs due to reduced fragmentation.Finally, we present an additional constraint to the Backfillingalgorithm called Full Locality, where the scheduler models the topologyof the platform as a fat tree and uses this model to assign jobs toregions of the platform where communication costs between processors isreduced. The experiment campaign is executed and results show that FullLocality is superior to all the previously proposed constraints, andspecially Basic Backfilling

Full textIn this thesis, we address the performance problem when searching in large databases of images. The processing of similarity queries is a computational challenge because of the dimensionality of the abstract representation for the images and size of the databases. We present two data organization methods that account for performance improvement. The first one is based on the clustering of the database in centralized settings. We derive an optimal range of values for the number of clusters to obtain from a database, which in conjunction with a searching algorithm allows to efficiently process nearest neighbor queries. However as the dimensionality and size of the database increase, a single computer is overwhelmed. The second method is based on data partitioning over a shared nothing machine. Based on the results of the first method, this method maximizes parallelism. We also derive the optimal number of processing nodes to maximize resource utilization. We performed extensive experiments with synthetic and real databases. They validate the proposals and show that the performance level is superior to existing approaches which beyond a certain dimensionality or database size become inefficient

Full textThe research originates from problems mentioned during the debate on the “efficient tort”. The term refers to the category of those actions, normally characterised by high levels of infringement, likely to produce a profit for the damaging part much greater than the loss incurred by the injured party. Therefore, the attention focused particularly on the most appropriate remedy for the identification of the right classification of this surplus value. Having excluded the other ways, the instrument has been found in the civil responsibility. More specifically, the research confers, to this responsibility, a sanction value, beyond the compensatory one, distancing itself from the traditional opinion. On these bases, the attention focused on the new regulation of the private enforcement in the field of “illecito antitrust”. The reference is to the latest D.Leg 19 January 2017 n. 3 intervened in the implementation of the Direcrive 2014/104 UE. This new regulation, maintaining the prohibition of overcompensation, in a field like the one in question, where the needs of deterrence are evidently revealed, exposes itself to various censures from the point of view of the constitutional legitimacy. Hence the attempt to provide a costitutionally oriented interpretation of the law in question that, hopefully, will be able to enlighten the future activity of the law and the legislator.

But, given their lack of experience of the alternative arena, they often integrate hedge fund strategies into their global asset allocation in a sub optimal way. Our objective is to familiarize investors with hedge fund strategies and provide them with tools allowing for an optimal integration of these alternative strategies in their global asset allocation. We analyze the return generating processes of the most popular strategies and highlight their genuine risk profile. We then design hedge fund indices that are both representative of their investment universe and investable. We finally introduce a new technology named Switching Kalman Smoother and use it analyse the performance of funds of hedge funds and their added-value at: i/ strategic allocation, ii/ tactical allocation, iii/ fund picking levels

Full textA new paradigm in human-robot collaboration has allowed to place robots nearby human operators, working close to each other in the industrial environment. As a consequence, human safety has become of paramount importance, together with production efficiency. New methods for robot programming can be exploited to simplify the way the trajectory is taught to the robot. In particular, the so-called "walk-through" technique allows to manually guide the robot through the desired trajectory. Since industrial robots are characterize by a stiff and non-backdrivable structure, the admittance control can be implemented to make them compliant. A force-torque sensor is mounted on the robot wrist and human forces can be translated into robot movements. However, the main limitation of admittance control is represented by rising instabilities when the robot interacts with a stiff environment. This can happen, for example, when the user grasps the robot wrist stiffening his/her arm. Instability induces high amplitude oscillations, threatening human operator's safety. To restore stability, a method for detecting rising oscillations and for modifying admittance control parameters have been presented. Once a desired trajectory has been taught to the robot, it is likely that the user needs to change the trajectory in a precise way and with a specific shape. A passivity-based framework to modify the trajectory online has been proposed, to manually drive the robot throughout the desired correction. To properly guarantee human safety and to obtain effective human-robot collaboration, the human prediction has been added to the system. Hence, when the human is working closely to the robot, the prediction algorithm determines whether the human operator is going to approach to the robot, in order to physically interact with it. Otherwise, the system has to properly react to the human movement, by avoiding the collision. For this reason, safety barriers have been built around each robot link and an optimization algorithm minimizes the difference between the nominal acceleration input and the commanded one. Finally, ROSSINI European project represents a concrete example of industrial scenarios where humans and robots work together. This project aims to develop an inherently safe hardware-software platform for the design and deployment of human-robot collaboration applications in manufacturing. Three industrial use-cases have been proposed and they regard assembly, handling and active cooperation. A two-layer scheduler manages task assignment and robot task scheduling. The optimization-based first layer assigns tasks to the human or to the robot, based on durations and costs. Job quality, agent capability, economic effort are some of the metrics used. The second layer, instead, manages robot parallel tasks, depending on the remaining time for the human to complete his/her task.

Full text. Lithography is a key step in micro / nanotechnology with applications in the fields of microelectronics, flexible electronics, photonics, photovoltaics, microfluidics and biomedical. This lithography step requires the use of a writable resist to act as a temporary mask for transferring patterns in the underlying material by etching or deposition. Nowadays, lithography uses synthetic organic resin, organic solvents and hazardous chemicals which is contrary to environmental issues and generates additional costs associated with risk and waste management. Furthermore, regulation rules (REACh, US pollution act) tend to move toward the protection of human health and the environment from the risks that can be posed by chemicals and promote alternative chemicals. In this context, this PhD work aimed at replacing conventional synthetic organic resist with a biopolymer. This biopolymer will not be modified by synthetic organic chemistry, will be compatible with conventional lithography instruments and it should be developable in water. It was demonstrated that chitosan was a positive tone resist allowing accomplishing a complete lithography-etching process. The whole process was performed in aqueous solution without the use of hazardous chemicals. 50 nm features were obtained after ebeam lithography/plasma etching into a silica layer without the use of an additional masking layer. 0.3-0.5 μm feature were obtained using photolithography

This research aims at verifying whether or not there is a relationship between the model of co-leadership and the improvement of effectiveness and efficiency in the Portuguese hotel business companies. For this purpose we used 1723 questionnaires, interviews, customers’ satisfaction, economic and financial performance and case studies. The results confirm that the stronger the co-leadership is, the better the effectiveness and the efficiency are. “Co-leadership” and “GOP” variables are both positive and strongly correlated between themselves and with other important indicators of operational effectiveness such as “Organizational Environment”, “Work Motivation” and “Customers’ Satisfaction”

Full textTraditionally, punishment has been justified by consequentialist and deontological theories. The place of utilitarianism as the bestknown consequentialist doctrine in the field of punishment has been the subject of several studies. However, utilitarianization of punishment has never been questioned. Utilitarianization of punishment refers to the process of adapting punishment to the principles of utilitarianism. This study proposes a contribution to the examination of this process by analyzing its theoretical fundamentals. It aims to reveal a crucial paradox in the field of punishment: utilitarian approach to punishment, repeatedly criticized, constantly adopted. . Utilitarianization of punishment was systematized with Bentham's Classical Utilitarianism, before arriving at its most scientific form with the Law and Economics Movement. This process is marked by a transition from effectiveness of punishment to efficiency of punishment. Therefore, this study aims to propose a new direction in criminal justice, one which does not instrumentalize human beings for economic prosperity, but at the same time takes into account efficiency, without replacing justice with efficiency, i.e., "Efficient Criminal Justice"

Malgré des limitations en basses fréquences dues au caractère bi–dimensionel du modèle, calculs et mesures indiquent que cet outil convient bien au rayonnement au–dessus de surface totalement réfléchissantes. Les effets de sol induits par des surfaces absorbantes n'est réalisée que de manière approchée. Un modèle d'effets de sol dus à un plan d'impédance donnée est donc dévelopé pour des sources de directivité arbitraire. Cette technique est essentiellement une alternative aux méthodes dites des équations intégrales. Par ailleurs, la solution exacte du problème est présentée.
Basé sur les deux outils de prédiction précédents, un modèle iteratif est dévelopé pour le rayonnement d'un pneumatique au–dessus de surfaces dont l'impédance est arbitraire. Des comparaisons avec des mesures d'amplification sonore due à l'effet dièdre montrent que ce modèle est efficient pour des surfaces absorbantes homogènes et inhomogènes. A l'aide de ce nouvel outil, une étude paramétrique examine les tendances du rayonnement du pneumatique au–dessus de chaussées absorbantes.
Le présent travail apporte de nouveaux éléments en matière de rayonnement de pneumatique / chaussée; il contribue en outre à l'étude des possibilités de réduction du bruit de trafic, notamment en utilisant des chaussées dites “silencieuses”.

Full textFaced with the irreparable prejudices arising from international crimes, except for the cases being prosecuted at the ICC and the processes of various Commissions and reparations funds of the UN, international law has been pontius-pilating when it comes implementing under domestic laws the rights of victims to reparations. This hypocrisy is particularly highlighted by the use of humanitarian aid. Domestic laws have systematically resorted to traditional practices to implement this right. This inclination towards traditional approaches is indeed at variance with the material elements of the law on reparations in as much as the context of the crimes, the scope of the damage, the vast number of victims and fluctuations in the types of perpetrators have simply made the traditional systems obsolete. Whence the quest for an efficiency paradigm hinged on «attempts» within transitional justice and reparations justice. Analyses of these attempts by experts reveal that a lot still has to be done. In the case of the DRC, and mindful of the shortcomings of the traditional legal system in mitigating the suffering of victims of international crimes, this study proposes a holistic approach to the development of a criminal reparations policy. This holistic approach requires a global response to the damage suffered by victims of international crimes. The reparations response to these multidimensional prejudices must reflect a global understanding of the law based on interdisciplinary and «social technology» considerations

Full textEvery year, more than 400 natural disasters hit the world. To assist those affected populations, humanitarian organizations store in advance emergency aid in warehouses. This PhD thesis provides tools for support decisions on localization and sizing of humanitarian warehouses. Our approach is based on the design of representative and realistic scenarios. A scenario expresses some disasters’ occurrences for which epicenters are known, as well as their gravity and frequency. This step is based on the exploitation and analysis of databases of past disasters. The second step tackles about possible disaster’s propagation. The objective consists in determining their impact on population on each affected area. This impact depends on vulnerability and resilience of the territory. Vulnerability measures expected damage values meanwhile resilience estimates the ability to withstand some shock and recover quickly. Both are largely determined by social and economic factors, being structural (geography, GDP, etc.) or political (establishment or not relief infrastructure, presence and strict enforcement of construction standards, etc.). We propose through Principal Component Analysis (PCA) to identify, for each territory, influential factors of resilience and vulnerability and then estimate the number of victims concerned using these factors. Often, infrastructure (water, telecommunications, electricity, communication channels) are destroyed or damaged by the disaster (e.g. Haiti in 2010). The last step aims to assess the disaster logistics impact, specifically those related to with: transportation flows capacity limitations and destruction of all or part of emergency relief inventories. The following of our study focuses on location and allocation of a warehouses’ network. The proposed models have the originality to consider potential resources and infrastructure degradation after a disaster (resilience dimension) and seek optimizing the equilibrium between costs and results (effectiveness dimension). Initially we consider a single scenario. The problem is an extension of classical location studies. Then we consider a set of probable scenarios. This approach is essential due to the highly uncertain character of humanitarian disasters. All of these contributions have been tested and validated through a real application case: Peruvian recurrent disasters. These crises, mainly due to earthquakes and floods (El Niño), require establishment of a first aid logistics network that should be resilient and efficient

Full textRadiation induced soft errors is a well-known problem in electronic designs. It happens due to ionizing radiation interaction with the electronic device resulting into temporary change of state. The change of state could be due radiation particle directly affecting the storage element known as single event upset (SEU) or a single event transient (SET) in any combinational element getting latched by storage element. With shrinking feature size and increase in packing density of CMOS devices used in electronics system, probability of occurrence of soft errors has gone up. Specific radiation hardening design and methodologies are required to make the electronic system tolerant to radiation induced faults. In this thesis work, I study the radiation induced effects on CMOS circuits and various methods used to assess and mitigate them. I investigated various soft error tolerant flip-flop and latch circuits which are the most basic sequential elements used in every electronic digital system. Each of these circuits have their own merits and demerits. These hardening techniques normally improves the radiation tolerance but degrades other parameters like area, power dissipation and speed of the circuit. Depending on the target application and radiation environment particular hardened circuits and methods are used to meet the acceptable failure rate with least possible penalty. Moreover, design and implementation cost is another factor which is considered. A new low power robust flip-flop circuit is discussed in detail, targeted for low to medium radiation tolerance applications which promises to improve power dissipation penalty. Another new flip-flop circuit and design methodology targeted for high radiation environment applications is discussed which employs spatial and temporal redundancy to overcome both SEU and SET faults and has embedded timing pre-error detection capability. This timing error sensing capability can be used at system level in many ways, to make system more efficient and to make it adaptable to changing operating environment and long-term device degradations. Both designs were implemented and validated in ST 90nm BCD technology process using CMOS devices using two test-chips. Complete design, implementation, simulation and test details are presented in this work. Comparative analysis is done with respect to standard D flip-flop circuit and other popular hardening strictures such as dual interlocked cell (DICE) based flip-flop, and triple modular redundancy (TMR) flip-flop. Proposed design appears to provide an efficient alternative to soft error tolerant designs.

Following this, we wanted to develop in this thesis new integrated strategies for maintenance, production, and inventory management of spare parts taking into account different operational constraints. These constraints include the change in the rate of production systems and its impact on the deterioration of the production system and on the maintenance plan and spare parts management. It was also interested in the origin and type of spare parts (new or used) used to ensure maintenance activities. In addition to the technical and economic influence of the origin of spare parts used in the production system, we also evaluated the environmental impact of the latter considering ADEME data.

Full textThis exploratory qualitative study focuses on the innovative application of the community of inquiry framework to synchronous online learning. This is the first study to report on efficient teaching strategies to foster a learning community in synchronous virtual graduate seminars and to explore this concrete application of blended online learning design. It is based on a multiple-case study (eight cases) that took place in five Francophone and Anglophone North American universities. Data collection consisted of forty hours of post facto observation of archived virtual seminars, sixty-one interviews conducted with faculty (n=9), teaching assistants (n=4), students (n=45) and instructional designers (n=3), as well as mid-term (n=50) and post-term (n=32) student surveys. The study confirms the importance of establishing a community of inquiry within a virtual graduate seminar. However, the socioconstructivist framework remains nebulous for several faculty and students, hence the importance of collaborative “culture” training. The study determines that socioconstructivist approaches contribute to the effectiveness of learning in virtual graduate seminars, identifies 30 attributes of a virtual graduate seminar and reports on 26 effective teaching practices that can be used to inform guidelines for quality online learning. It highlights the crucial role of the faculty member as the facilitator of a rich and ongoing dialogue in the virtual classroom. The multiple-case study reports high satisfaction levels among both faculty and students towards the virtual graduate seminar.

Full textCette recherche doctorale exploratoire de nature qualitative a pour objectif une application novatrice du cadre de la communauté d’apprentissage de cycle supérieur à l’apprentissage en ligne en mode synchrone. Il s’agit de la première étude à rendre compte de stratégies pédagogiques efficientes vers l’implantation d’une communauté d’apprentissage dans le cadre de séminaires d’études supérieures virtuels et de la première étude à explorer cette application concrète du e-learning intégral qu’est le séminaire virtuel. Elle repose sur une étude multi-cas (huit cas) menée en français et en anglais dans cinq universités nord-américaines. La collecte de données est fondée sur 40 heures d’observation post facto de segments d’archives de séminaires, 61 entrevues réalisées avec des professeurs (n=9), des auxiliaires d’enseignement (n=4), des étudiants (n=45) et des conseillers pédagogiques (n=3) et des sondages réalisés auprès des étudiants à la mi-trimestre (n=50) et après la formation (n=32). L’étude confirme l’importance de l’établissement d’une communauté d’apprentissage dans un séminaire d’études supérieures virtuel. Le cadre socioconstructiviste demeure toutefois nébuleux pour plusieurs professeurs et étudiants, d’où l’importance de former à la « culture » collaborative. L’étude démontre que les approches socioconstructivistes soutiennent effectivement l’efficacité de l’apprentissage. Elle cerne 30 attributs du séminaire virtuel et dégage 26 pratiques pédagogiques fructueuses pouvant baliser un apprentissage en ligne de qualité. Enfin, elle met en lumière le rôle crucial des professeurs en tant que facilitateurs d’un dialogue riche et soutenu. L’étude multi-cas rapporte un taux de satisfaction élevé tant de la part des professeurs que des étudiants à l’égard du séminaire d’études supérieures virtuel.
