Bolz, Marianne. "Régulation du destin cellulaire pendant la neurogénèse postnatale : rôle de l'innervation dopaminergique issue du mésencéphale." Thesis, Aix-Marseille, 2013. http://www.theses.fr/2013AIXM4098.
Full textIn the postnatal and adult mammalian brain neurogenesis persists in the subgranular zone of the hippocampal dentate gyrus and the subventricular zone (SVZ). In the SVZ slowly dividing stem cells give rise to neuroblasts that migrate to the olfactory bulb (OB) where they reach the granule and glomerular cell layer of the OB and differentiate into different interneuron subtypes including a small fraction of dopaminergic interneurons. The discovery of postnatal and adult neurogenesis has changed the view of the plasticity of the brain remarkably and raised the hope for new therapeutical approaches in the field of neurodegenerative diseases. Since in Parkinson’s disease the main motor symptoms are caused by the dopaminergic denervation of the striatum adjacent to SVZ, the understanding of the generation and differentiation of OB dopaminergic neurons has received special attention. Interestingly, the neurotransmitter dopamine itself has been suggested to influence olfactory bulb neurogenesis via direct innervation of SVZ by midbrain dopaminergic neurons. However, data on this topic have been contradictory. In this study, I investigated how dopaminergic innervation influences SVZ neurogenesis and the fate of SVZ progenitors. I combined a 6-OHDA model of dopaminergic denervation in postnatal mice with in vivo forebrain electroporation to specifically label lateral and dorsal SVZ progenitors and to follow their fate in the olfactory bulb

Full textThe vertebrate central nervous system (CNS), including the brain and the spinal cord), is composed of a large diversity of cells with highly specific functions. Neurons and glial cells are the two major classes of cells in this tissue. The neural tube, the embryonic draft of the CNS, is segmented into distinct domains of immature cells, named the neural progenitors. Each of these domains is dedicated to generate a particular neuronal or glial cell population such as oligodendrocytes, the myelinating cells of the CNS. The embryonic spinal cord serves as a good model for studying the development of these glial cells, whose spatial and temporal origin is well described. In this tissue, most of oligodendrocytes differentiate from a subset of neural progenitors localized in the ventral region and characterized by the expression of the transcription factor Olig2. Interestingly, these progenitors generate all of the motorneurons during the first steps of development; they further change their fate and produce oligodendrocytes. A rise in the activity of the morphogen factor Sonic hedgehog (Shh) on Olig2 progenitors induces oligodendrocyte development and stop motorneuron generation. However, this factor plays also a role in motorneurons induction at early stages ofdevelopment and cannot therefore be considered as a specific factor of oligodendrocyte induction raising the possibility that other signaling pathways could be involved, notably FGFs (Fibroblast Growth Factors), known to induce a second wave of oligodendrogenesis during fetal stages. Our work evidenced that the expression of FGFs receptors as well as up-regulation of FGF target genes in ventral neural progenitors was spatially and temporally correlated with the onset of oligodendrocyte generation. Functional analysis based on organotypic cultures of embryonic chicken spinal cords, showed that treatments with specific pharmacological inhibitors of FGF receptors are sufficient to inhibit oligodendrocyte production from Olig2 progenitors. Similar results were obtained following overexpression of a dominant-negative form of FGF receptors truncated from its intracellular domain. Conversely, activation of the FGF signaling pathway through overexpression of the FGF8 ligand is sufficient to stimulate oligodendrocyte generation from Olig2 progenitors. Finally, our work showed that FGFs stimulate oligodendrocyte differentiation both indirectly, by positively regulating the synthesis of Shh, and directly by targeting Olig2 progenitors. Hence, my PhD work evidences a major role of FGFs in initiating oligodendrocyte generation in the embryonic ventral spinal cord and highlights an unexpected dual activity of FGFs, involved in elevating Shh activity but also acting in cooperation with Shh to trigger Olig2 progenitors to follow an oligodendroglial fate
Verdier, Guillaume. "Variants of acceptance specifications for modular system design." Thesis, Toulouse 3, 2016. http://www.theses.fr/2016TOU30044/document.
Full textSoftware programs are taking a more and more important place in our lives. Some of these programs, like the control systems of power plants, aircraft, or medical devices for instance, are critical: a failure or malfunction could cause loss of human lives, damages to equipments, or environmental harm. Formal methods aim at offering means to design and verify such systems in order to guarantee that they will work as expected. As time passes, these systems grow in scope and size, yielding new challenges. It becomes necessary to develop these systems in a modular fashion to be able to distribute the implementation task to engineering teams. Moreover, being able to reuse some trustworthy parts of the systems and extend them to answer new needs in functionalities is increasingly required. As a consequence, formal methods also have to evolve in order to accommodate both the design and the verification of these larger, modular systems and thus address their scalability challenge. We promote an algebraic approach for the design of correct-by-construction systems. It defines a formalism to express high-level specifications of systems and allows to incrementally refine these specifications into more concrete ones while preserving their properties, until an implementation is reached. It also defines several operations allowing to assemble complex systems from simpler components, by merging several viewpoints of a specific system or composing several subsystems together, as well as decomposing a complex specification in order to reuse existing components and ease the implementation task. The specification formalism we use is based on modal specifications. In essence, a modal specification is an automaton with two kinds of transitions allowing to express mandatory and optional behaviors. Refining a modal specification amounts to deciding whether some optional parts should be removed or made mandatory. This thesis contains two main theoretical contributions, based on an extension of modal specifications called acceptance specifications. The first contribution is the identification of a subclass of acceptance specifications, called convex acceptance specifications, which allows to define much more efficient operations while maintaining a high level of expressiveness. The second contribution is the definition of a new formalism, called marked acceptance specifications, that allows to express some reachability properties. This could be used for example to ensure that a system is terminating or to express a liveness property for a reactive system. Usual operations are defined on this new formalism and guarantee the preservation of the reachability properties as well as independent implementability. This thesis also describes some more practical results. All the theoretical results on convex acceptance specifications have been proved using the Coq proof assistant. The tool MAccS has been developed to implement the formalisms and operations presented in this thesis. It allows to test them easily on some examples, as well as run some experimentations and benchmarks

Full textA design platform (DP) is a total solution to build a System-On-Chip (SOC). DP consists of a set of libraries/IPs, CAD tools and design kits in conformity with the supported design flows and methodologies. The DP specifications provide a wide range of information from technology parameters like Process-Voltage-Temperature (PVT) corners to CAD tools’ information for library/IP development. However, the library/IP developers have difficulties in obtaining the desired data from the existing specifications due to their informality and complexity. In this thesis, we propose methodologies, flows and tools to formalize the DP specifications for their unification and to deal with it. The proposed description is targeting to be used as a reference to generate and validate libraries (standard cells, I/O, memory) as well as complex IPs (PLL, Serdes, etc.). First, we build a suitable data model to represent all required information for library/IP development and then propose a specification language named Library Development Specification based on XML (LDSpecX). Furthermore, we introduce a reference-based method to create a reliable specification in LDSpecX and task-based keywords to efficiently extract data from it. On the basis of the proposed solutions, we develop a specification platform. Experimentally, we develop a standard cell library from the specification creation to library validation by using the specification platform. We show that our approach enables to create a complete and consistent specification with a considerable reduction in time. It also bridges the gap between the specification and current automatic system for rapid library/IP development

Full textAs the system complexity grows there is a need for new methods to handle large system design. One way to manage that complexity is to rise the level of abstraction of the specifications by using system level description languages. On the other side, as the level of abstraction rise the gap between the concepts used for the specification at the system level (communication channels, interacting processes, data types) and those used for hardware synthesis becomes wider. Although these languages are well suited for the specification and validation of complex real time distributed systems, the concepts manipulated are not easy to map onto hardware description languages. It is thus necessary to defines methods for system level synthesis enabling efficient synthesis from system level specifications. The subject of this thesis is the presentation of a new approach of generation of C and VHDL code from system level specifications in SDL. This approach solves the main problem encountered by previous approach : inter process communications. SDL communication can be translated in VHDL for synthesis. This is achieved by the use of a powerful intermediate form that support the modelling for synthesis of a wide range of communication schemes. This intermediate form allows to apply to the system a set of transformations in order to obtain the desired solution. The main refinement step, called communication synthesis is aimed at fixing the protocol and interface used by the different processes to communicate. The refined specification can be translated in C and VHDL and synthesised by commercial tools. We illustrate the feasibility of this approach through an application to a telecommunication example : the TCP/IP over ATM protocol
Javaheri, Fatemeh Negin. "Synthèse automatique de circuits numériques à partir de spécifications temporelles." Thesis, Université Grenoble Alpes (ComUE), 2015. http://www.theses.fr/2015GREAT083/document.
Full textThe work presented in this thesis aims at automatically prototype communication and control designs from declarative temporal specifications. From a set of PSL properties, we produce a synthesizable RTL design automatically. The proposed method is modular, in contrast to previously published methods that were based on automata theory. From each property, we produce a component that observes some operands and generates waveforms for the other operands: the reactant. First, a library of primitive reactants has been provided for FL and SERE operators. To this goal, a dependency relation is defined for each operator that expresses the dependency among its operands using the operator's semantics. Then, the dependency relation of each operator is interpreted as a hardware component that implements the operator: the operator's primitive reactant. Using this formalization, a method is proposed to automatically decide which signals of a property are observed and which are generated. In the cases when specifying the signal direction is not possible, a solver is implemented to identify the signal value. In addition, the way of identifying the value of the signal that is generated in several properties is addressed. The final circuit is the interconnection of the properties' reactants and solvers. A prototype tool SyntHorus2, which is an extension to HORUS, has been developed. It takes PSL properties as its inputs, and generates the synthesizable VHDL code of the circuit. In addition, it generates some complementary properties to verify if the set of specification is coherent and complete. The method is efficient, and synthesizes control circuits in a few seconds. Results obtained on classical benchmarks show that our technique compiles properties more efficiently than previous prototype tools

Full textThese works are related to the study of the code generation from B formal specifications. The main aspect that should be studied in the code generation is the modularity of the B language. We have expressed the B modularity with an Harper-Lillibridge-Leroy module system (an ML-like module system). This modelisation clarifies some aspects of the B modularity and gives us a representation of the B modules that are used during the phase of code generation. This new module system for the B language allows us to tackle a software production technique: the components based approach. This technique is often used conjointly with the design by contracts technique. Our code generation process allows to blend the design by contracts approach, the component based approach and the B method. We can take advantage of the three approaches to develop software
Vara, Larsen Matias. "B-COoL : un métalangage pour la spécification des opérateurs de coordination des langages." Thesis, Nice, 2016. http://www.theses.fr/2016NICE4013/document.
Full textModern devices embed several subsystems with different characteristics that communicate and interact in many ways. This makes its development complex since a designer has to deal with the heterogeneity of each subsystem but also with the interaction between them. To tackle the development of complex systems, Model Driven Engineering promotes the use of various, possibly heterogeneous, structural and behavioral models. In this context, the coordination of behavioral models to produce a single integrated model is necessary to provide support for validation and verification. It allows system designers to understand and validate the global and emerging behavior of the system. However, the manual coordination of models is tedious and error-prone, and current approaches to automate the coordination are bound to a fixed set of coordination patterns. Moreover, they encode the pattern into a tool thus limiting reasoning on the global system behavior. In this thesis, we propose a Behavioral Coordination Operator Language (B-COoL) to reify coordination patterns between specific domains by using coordination operators between the Domain-Specific Modeling Languages used in these domains. Those operators are then used to automate the coordination of models conforming to these languages. B-COoL is implemented as plugins for the Eclipse Modeling Framework thus providing a complete environment to execute and verify coordinated models. We illustrate the use of B-COoL with the definition of coordination operators between timed finite state machines and activity diagrams. We then use these operators to coordinate and execute the heterogeneous models of a surveillance camera system

Full textThe aim of this thesis is to bring a package of software tools included in a whole methodology dealing with mechatronic systems design. It comes as an add-on to the work already carried out at the laboratory in the field of the new generation of aircraft actuation systems: electromechanical actuators (EMA). This technology triggers new problematics leading the engineers to modify their development process as early as the specification phase, when mission profiles have to be generated/transformed/analyzed in order to simplify the design and ensure the validation step. Thus a Simulink toolbox has been created to meet the need for an information translator working as an intermediate between airframer and system-supplier. As for all the embedded systems, the designer has to face some performance-lifetime-integration trade-off, which can be considered as an optimization problem described by a set of equations and constraints. Particular attention is paid here to the conditioning of those explicit equations in order to obtain a standardized calculation sequence adapted to many optimization algorithms. The method and implemented software, both based on the graph theory, interact with the designer to inform him on the possible singularity and algebraic loop issues, providing some leads for their resolution. Finally, some preliminary sizing studies of landing gear and primary flight control surfaces (aileron and spoiler) actuation systems are presented to highlight the possibilities brought out by this innovative approach: integrated design with complex kinematics, collaborative multi-partners design, use of response surfaces to speed up the optimization

Full textThe aim of this work was to extend our understanding of the mechanisms regulating stem cell formation, specification and differentiation by studies in the non-bilaterian metazoan model Clytia hemisphaerica. Clytia, like other hydrozoan cnidarians, possess a particular population of multipotent stem cells called interstitial cells (i-cells), present during larval development and in the adult medusa, which are able to give rise both to somatic cell types and to gametes.In bilaterian animals Wnt/β-catenin signalling regulates fundamental developmental processes such primary body axis specification, but also regulates stem cell proliferation, lineage specification and differentiation. I investigated the role of Wnt/β-catenin signalling in i-cell specification and differentiation. The results obtained suggest that Wnt/β-catenin signalling is involved in the last step of differentiation for certain neuronal cell types, but not for somatic cell fate choice. In the second part of my study I investigated the role of Wnt/β-catenin signalling in i-cell formation during embryogenesis. The results indicated that during normal development i-cell formation is Wnt/β-catenin independent and probably driven by inheritance of germ plasm containing localised mRNAs from the egg animal pole. In contrast in embryo re-patterning following embryo bisection, Wnt/β-catenin signalling appears to be necessary for de novo i-cell formation in the absence of germ plasm. Thus two distinct mechanisms can lead to i-cell formation during embryogenesis. Overall the results obtained provided a better picture of how i-cells and their derivatives arise during embryogenesis and larval development

The proposed method explains how to identify, specify and implement collaborative processes and collaborative public services. In the proposed method business processes ensure interoperability at the business level, while reusable services, standards and SOA platform support interoperability at the IT level

Full textThis thesis is concerned with the monitoring of mixed-signal circuit simulations. In the field of hardware verification, the use of declarative property languages in combination with simulation is now standard practice. However the lack of features to specify asynchronous behaviors, or the insufficient integration of verification results, makes existing assertion and measurement languages unable to enforce mixed-signal requirements. We propose several theoretical and practical tools for the description and automatic monitoring of such behaviors, that feature both discrete and continuous aspects. For this we build on previous work on real-time extensions of temporal logic and regular expressions. We describe new algorithms to compute the distance from some simulation trace to temporal logic specifications, whose complexity is not higher than traditional monitoring. A novel diagnostic procedure is provided in order to efficiently debug such traces. The monitoring of continuous behaviors is then extended to other forms of assertions based on regular expressions. These expressions form the basis of our measurement language, that describes conjointly a measure and the patterns over which that measure should be taken. We show how other measurements implemented in analog circuits simulators can be ported to digital descriptions, this way extending structured verification approaches used for digital designs toward mixed-signal

Full textThis thesis proposes a methodological approach to characterize and anticipate organizational disruptions due to the introduction of an innovative concept offer in a « business to business » context. Therefore, it concerns products whom implementation induced both value creation for the customer and a change of professional interrelationships between trades within the client company. The challenge is to design new products or services that are better accepted wihtin purchasing companies by anticipating and integrating these impacts into the design process. The contributions of this research are positioned at two levels. First, a methodological approach is proposed. It is integrated into the creative process of suppliers. It enables to better describe the value creation opportunities by a better definition of structures and expectations of actors within customer organizations. These actors are seen as individuals but also as a scalable network. Moreover, a capitalization of data collected from customers is proposed. It is based on an adapated use of "customers concerns" and personas concepts. The information collected and interpreted are the basis of new standards for designers’ specifications. The first methodological contribution is a process called RACCP. It was developed from a case study: the upstream phase of a design process used in an industrial automation supplier. It helps the designer to model the changes implied by an offer concept on the operations of all stakeholders within the client company. This is possible by the combined use of three operational models since the upstream phase of the design process: the descriptive model of customer pains, actors profiles involved in these pains and representation of the interrelationships between them. The second contribution consists of an instanciation of all these three operational models in the convergence IT OT context. This contribution enables a better understanding of human and technical systems related to this context, sources of high value creation opportunities. This instantiation also provides the first proof of RACCP process efficiency

Full textThe development of correct formal specifications for systems and software begins with the analysis and understanding of client requirements. Between these requirements described in natural language and their specification defined in a specific formal language, a gap exists and makes the task of development more and more difficult to accomplish. We are facing two different worlds. This thesis aims to clarify and establish interactions between these two worlds and to evolve them together. By interaction, we mean all the links, exchanges and activities taking place between the different documents. Among these activities, we present the validation as a rigorous process that starts from the requirements analysis and continues throughout the development of their formal specification. As development progresses, choices are made and feedbacks from verification and validation tools can detect shortcomings in requirements as well as in the specification. The evolution of the two worlds is described via the introduction of a new requirement into an existing system and through the application of development patterns. These patterns manage both the requirements and their associated formal specifications ; they are elaborated from the description of the form of the requirements in the client document. They facilitate the task of development and help to avoid the risk of oversights. Whatever the choice, the proposed approach is guided by questions accompanying the evolution of the whole system and makes it possible to detect imperfections, omissions or ambiguities in the existing

Full textThis thesis presents a multi-perspective approach for the design of interactive safety-critical systems called the « Generic Integrated Modelling Framework ». The goal is to propose techniques, methods and tools for the model-based design while taking into account human and system-related erroneous behaviour. Our research focuses on task and system modeling, which like other models, are often developed from an error-free perspective, without taking into account human or system errors. These models are often developed by experts with different backgrounds and cultures. It is thus unlikely that the data gathered, analysed and documented will be represented in the same way. We have developed an approach which allows the integration of erroneous behaviour of both the users and the system via models (notably the task and system model). This perspective extends the boundaries of model based design since this additional information allows us to take into account previous failures. The main aim is to improve the design process in order to produce safer safety-critical interactive systems. This approach has been applied to two case studies : A fatal mining accident involving a gas management system within a cement plant An interactive cockpit application meeting the requirements of the ARINC 661 specification. The fundamental idée is to bring together within a single framework principle issues of user centred design within the safety-critical domain

Nous développons des algorithmes pour automatiser la construction des preuves, ainsi que des techniques heuristiques permettant d'accélérer cette construction. Ces algorithmes nous permettent de prouver des propriétés simples, comme par exemple la propriété qu'un signal vaut toujours vrai pour un ensemble de processeurs et une durée déterminés. Nous présentons ensuite et commençons à développer des pistes afin d'enrichir notre logique pour exprimer des propriétés plus complexes, comme par exemple des propriétés d'exclusion mutuelle. Nous présentons quelques tactiques de preuve pour ces propriétés plus riches.
