Повний текст джерелаThe development of machine learning techniques, particularly neural networks, combined with the development of new information and communication technologies, is shaking up our societies through technological advances in a variety of sectors. The building sector is not spared, so these techniques may represent an interesting opportunity in a context where greenhouse gas emissions must be drastically reduced. The objective of this work is to assess the interest of these techniques in the field of building energy, with the aim of reducing energy consumption and improving thermal comfort. In addition, we ensure that this evaluation is carried out with a global vision, by placing the possible advantages in front of the different needs relating to the development of these technologies. This thesis work is organized in three parts preceded by a detailed introduction intended to give the reader an overview of the various contextual elements, thus allowing the thesis work to be placed in perspective. We then give in the first part the theoretical framework needed to understand the problems encountered during the elaboration and creation of neural networks for building energy applications. Then, a bibliographical study giving the reader a broad overview of the various applications of neural networks in the field of building energy is presented. The second part is devoted to the calibration of the building model that is then used to test and evaluate a predictive controller implementing neural networks. After an explanation of the method used and a detailed presentation of the model, a complete analysis of the calibration results is carried out. We conclude this part with observations and recommendations regarding the standard calibration guidelines recommended by three international organizations. Finally, a practical application using neural networks for the predictive control of indoor temperature is presented in the third part. After a theoretical introduction concerning predictive control, we detail the method employed to train the neural networks used. The results obtained in simulation with a predictive controller are then analyzed and compared with those obtained with two reference controllers for various simulation hypothesis. The predictive controller is thus tested in several scenarios, ranging from an ideal situation to more realistic operating conditions, including two different types of heat emitters, namely radiant ceilings and underfloor heating

Повний текст джерелаConcerning access control, can the following question be addressed : "Is the access control system decidable ?". In other words : is it true that starting from a safe state of protection, we can assume at any time that is no intrusion which will endanger our system ?. In order to answer this question, we propose to model the access control system in the form of a graph of roles. The roles, which represent the vertices of graph contain, according to the security-policy, certain number of privileges. Every privilege represents one or several access rights on a given object. We presented two methods of use of this graph : The first consists in using an algorithm, which we developed by basing itself on the algorithms of the theory of the graphs, permit to search all over the path of the graph in order to find illicit privilege transfer. The second consists in storing our graph in a directory LDAP, this which brings us to develop a new plan LDAP to represent our graph of roles

Повний текст джерелаThis thesis addresses the challenge of optimizing the management of canals, a complex task due to their extensive scale and distinctive attributes, including intricate dynamics, considerable time delays, and minimal bottom slopes. Specifically, the central goal is to ensure the navigability of the network, which involves maintaining safe water levels for vessel travel, through control theory. More precisely, the water levels must remain within a predefined range around a setpoint. Additionally, typical aims encompass reducing operational costs and enhancing the equipment’s life expectancy. In this regard, another objective in the management of such networks is replacing the possible sensors across canals by applying a moving robot to take the required measurements. To accomplish effective management, it becomes imperative to ensure efficient control over hydraulic structures such as gates, pumps, and locks. To this end, a control algorithm is introduced based on an existing model derived from the Saint-Venant equations. The modeling approach simplified the original complex description providing adaptability and facilitating the systematic integration of both current and delayed information. However, the resulting model formulation falls within the category of delayed descriptor systems, necessitating extensions to standard control and state estimation tools. Model predictive control and moving horizon estimation methods can be readily tailored for this formulation, while also adapting physical and operational constraints seamlessly. Given the extensive nature of canals, an evaluation of the digital twin was untaken to address the critical need for advanced tools in the management of such networks. By harnessing the capabilities of digital twins, we aimed to enhance our understanding of canal dynamics, past scenarios, and management strategies. This evaluation sought to bridge the gap between theory and practical implementation, offering a tangible means to playback past events, test diverse management approaches, and ultimately equip decision-makers with robust criteria for informed and effective network management.The methodologies presented above are applied to a practical case study, a canal in the northern region of France. The objective is to validate the efficacy of these approaches in a real-world context.While centralized MPC provides resilience through its receding-horizon approach, its deterministic nature limits its ability to systematically address uncertainties. To effectively tackle these system uncertainties, the implementation of Stochastic MPC (SMPC) has been adopted. SMPC integrates probabilistic descriptions into control design, offering a methodical approach to accommodating uncertainties. In this context, the application of SMPC is interconnected with a mobile robot aimed at replacing existing sensors along the canal to capture measurements. Consequently, a part of this thesis focuses on the design of SMPC in conjunction with a mobile robot. This approach has been applied to an ASCE Test canal to evaluate its effectiveness

Повний текст джерелаNowadays, information technologies provide users ability to work with anyone, at any time, from everywhere and with several heterogeneous devices. This evolution fosters a new distributed trustworthy collaboration model where users can work on shared documents with whom they trust. Multi-synchronous collaboration is widely used for supporting collaborative work by maintaining simultaneous streams of user activities which continually diverge and converge. However, this model lacks support on how usage restrictions on data can be expressed and checked within the model. This thesis proposes "C-PPC", a multi-synchronous contract-based and trust-aware collaboration model. In this model, contracts are used as usage rules and users collaborate according to trust levels they have on others computed according to contract compliance. We formalize contracts by using deontic concepts: permission, obligation and prohibition. Contracts are enclosed in logs of operations over shared data. The C-PPC model provides a mechanism for merging data changes and contracts. Any user can audit logs at any time and auditing results are used to update user trust levels based on a trust metric. We propose a solution relying on hash-chain based authenticators that ensures integrity of logs and user accountability. We provide algorithms for constructing authenticators and verifying logs and prove their correctness. A set of experimental results shows the feasibility of the C-PPC model

Повний текст джерелаLes travaux de cette thèse s'inscrivent dans le cadre de la validation formelle et le contrôle réactif de calculs à haute performance sur systèmes-sur-puce (SoC).
Dans ce contexte, la première contribution est la modélisation synchrone accompagnée d'une transformation d'applications en équations synchrones. Les modéles synchrones permettent de résoudre plusieurs questions liées à la validation formelle via l'usage des outils et techniques formels offerts par la technologie synchrone. Les transformations sont développées selon l'approche d'Ingénierie Dirigé par les Modèles (IDM).
La deuxième contribution est une extension et amélioration des mécanismes de contrôle pour les calculs à haute performance, sous forme de constructeurs de langage de haut-niveau et de leur sémantique. Ils ont été défini afin de permettre la vérification, synthèse et génération de code. Il s'agit de déterminer un niveau d'abstraction de représentation des systèmes où soit extraite la partie contrôle, et de la modéliser sous forme d'automates à états finis. Ceci permet de spécifier et implémenter des changements de modes de calculs, qui se distinguent par exemple par les ressources utilisées, la qualité de service fournie, ou le choix d'algorithme remplissant une fonctionnalité.
Ces contributions permettent l'utilisation d'outils d'analyse et vérification, tels que la vérification de propriétés d'assignement unique et dépendance acyclique, model checking. L'utilisation de techniques de synthèse de contrôleurs discrets est également traitée. Elles peuvent assurer la correction de faˆ on constructive: à partir d'une spécification partielle du contrôle, la partie manquante pour que les propriétés soient satisfaites est calculée. Grâce à ces techniques, lors du développement de la partie contrôle, la spécification est simplifiée, et le résultat est assuré d'être correct par construction.
Les modélisations synchrone et de contrôle reposes sur MARTE et UML. Les travaux de cette thèse sont été partiellement implémentés dans le cadre de Gaspard, dédié aux applications de traitement de données intensives. Une étude de cas est présentée, dans laquelle nous nous intéressont à une application de système embarqué pour téléphone portable multimédia.

Повний текст джерелаRepresenting more than one-third of global electricity consumption, buildings undergo the most important sector capable of reducing greenhouse gas emissions and promote the share of Renewable Energy Sources (RES). The integrated RES and electric energy storage system in buildings can assist the energy transition toward a low-carbon electricity system while allowing end-energy consumers to benefit from clean energy. Despite its valuable advantages, this innovative distributed Building Microgrids (BM) topology requires significant changes in the current electric grid, which is highly dependent on grid energy policies and technology breakthroughs.The complexity of designing a robust Energy Management System (EMS) capable of managing all electric components inside the microgrid efficiently without harming the main grid stability is one of the greatest challenge in the development of BM. To mitigate the harmful effects of unpredictable grid actors, the concept of self-consumption has been increasingly adopted. Nonetheless, further technical-economic analysis is needed to optimally manage the energy storage systems to attain higher marks of self-consumption.Faceing these issues, the purpose of this doctoral thesis is to propose a complete framework for designing a building EMS for microgrids installed in buildings capable of maximising the self-consumption rate at minimum operating cost. Among all possible control architectures, the hierarchical structure has proved effective to handle conflicting goals that are not in the same timeframe. Hence, a Hierarchical Model Predictive (HMPC) control structure was adopted to address the uncertainties in the power imbalance as well as the trade-off between costs and compliance with the French grid code.Considering that buildings are not homogeneous and require solutions tailored to their specific conditions, the proposed controller was enhanced by two data-driven modules. The first data-driven algorithm is to handle inaccuracies in HMPC internal models. Without needing to tune any parameter, this algorithm can enhance the accuracy of the battery model up to three times and improve up to ten times the precision of the hydrogen storage model. This makes the building EMS more flexible and less dependent on pre-modelling steps.The second data-oriented algorithm determines autonomously adequate parameters to HMPC to relieve the trade-off between economic and energy aspects. Relying only on power imbalance data analysis and local measurements, the proposed hierarchical controller determines which energy storage device must run daily based on the estimation of the annual self-consumption rate and the annual microgrid operating cost. These estimations decrease microgrid expenditure because it avoids grid penalties regarding the requirements of annual self-consumption and reduces the degradation and maintenance of energy storage devices.The proposed EMS also demonstrated being capable of exploiting the potentials of shifting in time the charging of batteries of plug-in electric vehicles. The simulation confirmed that the proposed controller preferably charges electric vehicles’ batteries at periods of energy surplus and discharges them during periods of energy deficit, leading the building microgrid to reduce grid energy exchange. The results also showed that electric vehicle batteries' contribution depends on the size of the vehicle parking, their arrival and departure time, and the building’s net power imbalance profile. In conclusion, through simulations using the dataset of both public and residential buildings, the proposed hierarchical building EMS proved its effectiveness to handle different kinds of energy storage devices and foster the development of forthcoming building microgrids
