Esposito, Fiammetta. "Tueurs en série français : regards croisés de la psychopathologie et de la criminologie à propos de six meurtriers multiréitérants français". Poitiers, 2007. http://www.theses.fr/2007POIT3006.
Testo completoA serial killer never acts without motive : his murderous acts are triggered by a specific drive. The motivations of a serial killer are deeply hidden in his pathological psyche. Each of his gestures and each word he will pronounce about the homicides he committed can be decoded particulary thanks to criminology and psychopathology. Upstream, we shall look into the biography of these atypical criminals ; downstream, we shall raise the question of their future in detention and their access to medical attention, with regard to the danger they represent. The first part of this study lays the foundations of the criminal and behavioral analysis, which basis will help study the profile of six French criminals in the second part. The third part consists of a more methodological approach for the use of the practitioners : judicial police officers, magistrates, lawyers ans psychiatrists
Toure, Almamy. "Collection, analysis and harnessing of communication flows for cyber-attack detection". Electronic Thesis or Diss., Valenciennes, Université Polytechnique Hauts-de-France, 2024. http://www.theses.fr/2024UPHF0023.
Testo completoThe increasing complexity of cyberattacks, characterized by a diversification of attack techniques, an expansion of attack surfaces, and growing interconnectivity of applications with the Internet, makes network traffic management in a professional environment imperative. Companies of all types collect and analyze network flows and logs to ensure the security of exchanged data and prevent the compromise of information systems. However, techniques for collecting and processing network traffic data vary from one dataset to another, and static attack detection approaches have limitations in terms of efficiency and precision, execution time, and scalability. This thesis proposes dynamic approaches for detecting cyberattacks related to network traffic, using feature engineering based on the different communication phases of a network flow, coupled with convolutional neural networks (1D-CNN) and their feature detector. This double extraction allows for better classification of network flows, a reduction in the number of attributes and model execution times, and thus effective attack detection. Companies also face constantly evolving cyber threats, and "zero-day" attacks that exploit previously unknown vulnerabilities are becoming increasingly frequent. Detecting these zero-day attacks requires constant technological monitoring and thorough but time-consuming analysis of the exploitation of these vulnerabilities. The proposed solutions guarantee the detection of certain attack techniques. Therefore, we propose a detection framework for these attacks that covers the entire attack chain, from the data collection phase to the identification of any type of zero-day, even in a constantly evolving environment. Finally, given the obsolescence of existing datasets and data generation techniques for intrusion detection, and the fixed, non-evolving, and non-exhaustive nature of recent attack scenarios, the study of an adapted synthetic data generator while ensuring data confidentiality is addressed. The solutions proposed in this thesis optimize the detection of known and zero-day attack techniques on network flows, improve the accuracy of models, while ensuring the confidentiality and high availability of data and models, with particular attention to the applicability of the solutions in a company network
Pi, Lei. "Langage de description d'architecture : sémantique et analyse comportementale". Toulouse, ISAE, 2010. http://www.theses.fr/2010ESAE0008.
Testo completoThe evolution of the complexity of critical embedded systems currently leads to use on the one hand modeling languages closest to the specifications of the designer’s job, and on the other hand verification tools (model checker) to ensure the correction of the system with respect to the correctness requirements and the real-time constraints. It is in this context that the project TOPCASED has been launched to propose a framework to develop critical real-time systems based on formal verification and dedicated languages. The methods and tools from this work are an integration of formal verification in the process and platform development. AADL (the SAE Architecture Analysis and Design Language) est un langage de description d’architecture qui permet de décrire autant les aspects matériels que les composants logiciels d’un système. In order to make easer the connection of model checkers to those languages, the pivot FIACRE language (Format Intermédiaire pour les Architectures de Composants Répartis Embarqués) has been developed. It is powerful enough to support the expression of the semantics of real time. In this context, I studied the semantic of the AADL execution model and its expression in different formalisms, like TASM, BIP, ACSR and FIACRE. They revealed the need to unify these formalisms. I worked on a new definition of the semantics of the language FIACRE. Then I propose to enrich FIACRE by a suspend/resume operator and a mechanism for resource allocation of which usefullness is illustrated on several examples. However, the induced expressive power no longer permits the use of TPN for the verification of extended FIACRE models. Thus, I propose a translation of the extended FIACRE language into a class of TPN newly introduced in the environment Tina: Petri nets with stopwatches

Testo completoThe thesis examines the conditions under which certain cognitions, relating to a person's feeling of control and responsability, influence behaviour. It brings together two theoretical fields of cognitive social psychology, causal explanations of reinforcement (locus of control) and of behaviours (attribution), on the one hand, and the theories on behaviour patterns and behaviour rationalization (commitment and cognitive dissonance), on the other. The hypothesis mat the processes of internal and external explanations influence behaviour and subsequent attitude change is interpreted in a new light, distinguishing between behaviours and contrasting attitudes : the experimental part begins by experimenting with and comparing different methods for activating causal explanatory processes. It then proceeds to experiment with the effect of causal explanatory processes, wether activated or not, on pro and counterattitudinal commitment. Counter-attitudinal requests (re. Trade-unionism) trigger a heteronomous process which gives rise to independence between causal processes and behaviours arising from forced submission. Pro-attitudinal requests (for blood-giving and homework aid) generate an autonomous process predisposing to commitment and attitude change in internals compared with externals. The intervention of causal explanatory models is cost-related : the more costly the pro-attitudinal request is, the more the internals differ from the externals in commitment and subsequent attitude change

Testo completoDebugging, as usually understood, revolves around finding and removing defects in software that prevent it from functioning correctly.That is, when one talks about bugs and debugging one usually means functional bugs and functional debugging.In the context of this thesis, however, we will talk about performance bugs and performance debugging.Meaning we want to find defects that do not cause a program to crash or behave wrongly, but that make it run inefficiently, too slow, or use too many resources.To that end, we have developed tools that analyse and model the performance to help programmers improve their code to get better performance.We propose the following two performance debugging techniques: sensitivity based performance bottleneck analysis and data-dependence profiling driven optimization feedback.Sensitivity Based Performance Bottleneck Analysis:Answering a seemingly trivial question about a program's performance, such as whether it is memory-bound or CPU-bound, can be surprisingly difficult.This is because the CPU and memory are not merely two completely independent resources, but are composed of multiple complex interdependent subsystems.Here a stall of one resource can both mask or aggravate problems with another resource.We present a sensitivity based performance bottleneck analysis that uses high-level performance model implemented in GUS, a fast CPU simulator to pinpoint performance bottlenecks.Our performance model needs a baseline for the expected performance of different operations on a CPU, like the peak IPC and how different instructions compete for processor resources.Unfortunately, this information is seldom published by hardware vendors, such as Intel or AMD.To build our processor model, we have developed a system to reverse-engineer the required information using automatically generated micro-benchmarks.Data-Dependence Driven Polyhedral Optimization Feedback:We have developed MICKEY, a dynamic data-dependence profiler that provides high-level optimization feedback on the applicability and profitability of optimizations missed by the compiler.MICKEY leverages the polyhedral model, a powerful optimization framework for finding sequences of loop transformations to expose data locality and implement both coarse, i.e. thread, and fine-grain, i.e. vector-level, parallelism.Our tool uses dynamic binary instrumentation allowing it to analyze program written in different programming languages or using third-party libraries for which no source code is available.Internally MICKEY uses a polyhedral intermediate representation IR that encodes both the dynamic execution of a program's instructions as well as its data dependencies.The IR not only captures data dependencies across multiple loops but also across, possibly recursive, procedure calls.We have developed an efficient trace compression algorithm, called the folding algorithm, that constructs this polyhedral IR from a program's execution.The folding algorithm also finds strides in memory accesses to predict the possibility and profitability of vectorization.It can scale to real-life applications thanks to a safe, selective over-approximation mechanism for partially irregular data dependencies and iteration spaces

Testo completoThe Powered wheelchairs (PW) allowed many people with motor disabilities to find a suitable mobility, which improved their quality of life. Hence, a vast field of activities has become accessible for them. When prescribing a PW or in a learning phase, however, it is necessary to evaluate the ability of these people to drive a wheelchair. In this context, our goal is to determine relevant parameters to describe the quality of driving on PW for people with disabilities. First, we modeled the pilot-PW system using the OPCM (Optimal Preview Control Model) model proposed by Sharp. This model is based on the preview distance (Dp) of the user during his driving. This distance has been estimated thanks to an eye-tracking system combined with the ViEW 3D simulator of the LCOMS laboratory. A panel of 15 healthy subjects was recruited to drive the PW on a 3D simulator and to validate the OPCM modeling. This distance Dp allows to describe the behavior of the pilot. If this distance is important, it guarantees the tracking trajectory of the OPCM model. Otherwise, the OPCM model diverges. This shows that if the user looks a long part of his future path, he will better anticipate the future control applied to the PW (change of direction, braking, etc.), which allows him to follow his path. In this situation the user has a tracking behavior. In the otherwise, the user’s behavior is rather compensatory. Then, an analysis of preview distance Dp with respect to the different zones of the path (tight slalom, turn, wide slalom), showed that the parameter Dp can be used to differentiate the different driving behaviors related to the different situations of the path. Next, we compared the preview distance between two groups, familiar and novice with regard to the PW driving. The analysis showed that the familiar group has a greater distance value than the novice group. Finally, a last experiment took place at the Rehabilitation Center of Flavigny sur Moselle (54, France). We estimated the preview distance (Dp) for subjects with severe motor impairment, in order to validate the parameter Dp as a performance indicator. A case study analysis was established on five children with disabilities comparing their results with those previously obtained with the healthy subjects

Testo completoThis paper aims at giving a more comprehensive understanding of the way the prices are set up on option markets. Prediction models are derived. To facilitate their understanding we propose to split price formation process into two phases: -a first one which says how an equilibrium can be reached taking into account the way opposite operators see the future market movements and why some equilibrium can be reached or not. -second, based upon the information revealed by active operators, when enough information is given along time, we show that it is possible give probabilities of market tendencies. This will lead to a behavioral financial model build in the context of utility theory and stochastic dominance, leading to a better understanding of capital markets and option markets. . The purpose of the model will be to permit high probability forecasts in some few specific situations. For this, information coming from buyers as sellers is exploited, each operator bringing his own particular vision of future price market movements

Testo completoThis study was designed to determine the role of an exposure to language at an early age on the management of social relationships in adolescence, considered at two levels: perception of self and underlying psychodynamic aspects. This study was conducted by means of a comparison of 200 adolescents suffering from a congenital deafness to 200 hearing adolescents, boys and girls between 10 and 15 years old. Self perception was assessed using a self administered questionnaire including 60 items pertaining to human relationships in various contexts, whereas the psychodynamic aspects were explored using a projective technique, the village test, which was analyzed by means of a specifically designed scale of indicators. Data processing consisted of, on the one hand, a thematic comparison of the two populations and the elaboration of typologies, on the other hand, an analysis of the correlations between the types of self perception and the underlying psychodynamic structure. The findings lead to consider a double role of language: a support for the acquisition of the control on impulsivity and a support for the separation-individuation process. Practical implications of these results include interventions, at an individual or collective level, upstream or downstream of the development of social skills

Testo completo28 mother-infant dyads were videotaped longitudinally at home to evaluate impacts of sides and the home-monitoring on the subsequent infant. Infant and maternal behaviors, maternal reactivity to infant crying and maternal sensitivity were analyzed when infants were 2, 4, 9 and 12 months of age. Behaviors were scored using a check-list sheet with a fixed time base of 5 sec. Distinctive patterns of dyadic interaction were identified between the experimental groups (g1: 8 monitor infants, g2: 10 non-monitor infants) and the control group (g3: 10 controls): the mothers of the first two group reacted to the infant distress more frequently, more quickly and more gestually than did control mothers, who answered less frequently and more visually. Generally, we attribute a protective role to the monitor, but the results suggest that the mothers of the monitor infants remained extremely anxious. At 2 and 4 months, the mothers of g1 provided the same behavioral pattern than mothers of g2; the only difference was in the nature of their behavior: the first preferred the visual modality whereas the others preferred the tactile modality. In fact, the mothers of g2 were more reactive, more intrusive and less effective than mothers of g1. At 9 and 12 months the mothers of g1 became more sensitive, so we can think that home-monitoring is helpful. But the analysis of the infant behaviors and the differences with the control group indicate the importance of the infant contributions to interaction, and underline the absolute necessity to support these extremely anxious mothers of g1 and g2

Testo completoThis thesis deals with the impact of agriculture on health and the environment from a behavioural economics perspective. Focusing on the controversial use of pesticides in the winegrowing industry, I demonstrate the importance of considering the trade-offs made by economic actors in order to understand the obstacles hindering a shift to sustainable production. On the consumer side, I experimentally measure the competitive effect of certification (organic farming) and technological innovations (e.g. resistant grapevines, reduction of sulphites) on consumers’ preferences. I observe that consumers are partly willing to review their taste requirements in exchange for high environmental quality level, but that their motives are essentially health-oriented, generating contradictory signals towards producers. Besides, selecting the best products is hampered by the little information consumers are provided with. On the supply side, I argue that ability to meet demand is strongly limited by the inertia of the production system. This inertia can be attributed to risk aversion but again, to a large extent, to a lack of information, rather than being, as is often suggested in an agricultural context, the result of imitation. This lack of information this time concerns the various options available upstream, in this instance, on the part of winegrowers. I then provide guidelines for public regulatory policies, at global level or at more local level of corporate governance, to enable a match between supply and societal demand

Testo completoAlsace is one of the French regions the most affected by muddy floods. The urban occupation, physical and agricultural characteristics promote their formation (loamy soils, large crops areas). Our reflection contributes to answer to the contribution of taking into account levels of risk perception by stakeholders to determine / modify their behaviour, and to improve policies to reduce risk by insisting on the expectations of population. Eleven Alsatian municipalities were chosen to be surveyed about the perception and representation of the risk of muddy floods. The method developed four objectives: (i) allowing a detailed analysis of the behavior of population concerned by this risk, (ii) provide data for improving economic behaviors’ models, (iii) taking into account degrees of risk perception to improve the definition of preventive campaigns, (iv) creating a comparative mapping of variations in risk perception and “real” risk situations. " Our results show that the risk perception varies depending on the concerned population, its involvement in the risk management and the level of damage incurred. The economic approach insist of the use of important factors (experience, threat of the risk, etc. ) in modelling of individuals’ behaviors facing natural hazards

Construction of an observation table for group behaviours which allows us to demonstrate that : - co-operation between children can be developped in the second cycle. - in this situation, the children communicate for a single reason : in order to find the solution for the problem encountered. - they show a high degree of autonomy both in pratice and in problem solving. - co-operation favorises better results in reading-writing. Two conditions are necessary for the co-operation to be efficient : - a regulating and conflictual presence of peers. - an accompanying presence by the adult-teacher

Testo completoThis PhD dissertation presents a contribution to the analysis of the behaviour’s heterogeneity on the stock markets. It proposes, firstly, a review of the literature of heterogeneous agents’ models which allow reproducing stylised facts observed in the real markets such as an excessive volatility of prices, an important transaction’s volume, grouped volatilities, a fat tail distribution and a mean return, which contradicts the markets efficiency and the assumption of a representative agent. These models also, allow explaining the bubbles emergence and prices behaviours sometimes chaotic. The explicit heterogeneity hypothesis, in modelling, leads representations more adequate with reality. In addition, we propose empirical works on investor’s behaviours heterogeneity in the French stock market, for individuals stocks and following different observation frequencies. The first estimation considers a model of evolutionary strategies selection. We noted the persistence of the difference between prices and fundamental values. We also noticed the confusion of investors in crisis periods with a brutal change between strategies and this often for the majority of investors. We concluded for these periods that there are imitation phenomena related on lack of information and uncertainty climate. This result agrees with real market during bubble formation and bursting of a bubble. These results are generally confirmed by the second estimation of the LSTAR-GARCH model which explicitly considers a conditional variance and supposes different assumptions from the first

Testo completoIn this study, we investigated in mice the sensitivity to two psychotropic : a psychostimulant (cocaine) and an antidepressant (fluoxetine). We first explored the impact of a disturbance of the antenatal environment (cocaine in utero) on adult behavioral sensitization to cocaine. We observed a modification of the behavioral sensitization profile to cocaine in mice prenatally exposed to this drug. Otherwise, we studied the role of the phosphatase calcineurin in the effects of this two psychotropic using genetic overexpression (CN98 mice). We observed that the behavioral and molecular responses to cocaine and fluoxetine were potentiated and the sub-cellular localization of a glutamate receptor sub-unit was disturbed. Finally, many phenotypes modified in these mice had been normalized by a mood regulator treatment (valproate), which makes it possible to discuss of the use of the animal models for the study of the psychiatric diseases

Testo completoThis work consists in the application of a relationnal approach in sociology. It is presented in five parts : In the first, we focus on the principles and uses of action theory ; we draw attention to the different theoretical initiatives of social science experts who have understood the limits of action theory and aim to overcome them ; we lay down the principles of a relational approach ; we present a series of hypotheses, linked to each approach (action theory and relational theory), and the indicators which will serve to verify these hypotheses. In the second section, we discuss the method udes to establish a comparative analysis of the two models in question ; we point to the way in which it allows for a verification of both sets of principles ; we explain how the data extracted from the filming of committee meetings in France and Canada serves as the terrain for two types of analysis : one with an emphasis on discourse and the other on the social actor. In the third section are presented the results of the study, through which we discover that human dynamics further shape individual behavior than do human intentions and that principles behind action theory and its derivatives give access to mere possibilities of social action. In this same section, we establish the non incidence of external conditions on the presence of intention. The following part draws the consequences of these observations and, along with the fifth section, elaborates on the necessity for sociology to theorize in a way which is more in correspondence with its primary object of study

Testo completoDiscussions with twelve young people and a analysis with a clinical pyshology approach of their statements made it possible to understand the problems with which they live and the difficulties of installation of their life projects. The educational and emotional deficiencies of the young people in trouble slow down the installation of their life projects. Psycho-dynamic componants have to be revived like the relation with the other and the activation of the forces of Ego and the revalorization of oneself. It is by finding back some self-confidence and some confidence in the other through the installation of a total, stable and continuous acompaniment that a concrete training on know how, on how to to live and how to be and the reappeanrence of self-confidence will take place. Parallel discussions with trainers make it possible to etablish a link between expectations of the the young people looking for insertion and what the trainers can bring to them. On total we present the possible ways for young people in trouble from 16 to 25 years to instal a life project
Ajmone, Marsan Giulia. "Nouveaux paradigmes et méthodes mathématiques pour systèmes complexes dans l'économie comportementale". Paris, EHESS, 2009. http://www.theses.fr/2009EHES0139.
Testo completoThis dissertation is devoted to the mathematical investigation of properties of complex socio-economic systems, where individual behaviors, and their interactions, exert a crucial influence on the overall dynamics of the whole system. In order to understand the importance of such an investigation, it is necessary to briefly analyze some conceptual aspects relating to the interaction between applied mathematics and socio-economic sciences. The main issue in this field consists in coupling the usual qualitative interpretation of socio-economic phenomena with an innovative quantitative description by means of mathematical equations. This dialogue, however difficult, is necessary to reach a deeper understanding of socio-economic phenomena, where deterministic rules may be stochastically perturbed by individual behaviors. The difficulty mostly stems from the fact that the behavior of socio-economic systems, where the collective dynamics differ from the sum of the individual behaviors, is aparadigmatic example of a complex system. The mathematical framework presented in this dissertation is built by suitable developments of the so-called mathematical kinetic theory for active particles, which proved to be a useful reference for applications in many fields of life sciences. The description of a system by the methods of the mathematical kinetic theory essentially implies the definition of the microscopic state space of the in¬teracting entities and of the distribution function over this state space

Testo completoVia its qualities, experiential art tends to intermingle the actual artwork and experience. In contemporary art, certain artists produce installations that call for a strong corporeal investment on the part of the spectator/vistitor, that call to be experienced. This thesis studies the process of reception of the installation as experiential artwork. How does the experience of this kind of work get constructed ? What are its modalities and features ? After a brief presentation of this type of art, the thesis offers a first theoretical approach that focuses on the technical assemblage so as to single out the situationbased specificities of it : spatio-temporal, practical, formal and structural. A second theoretical approach then looks at the visitor's experience so as to make sense of how the assemblage's specificities can impact his/her psycho-motor and sensori-motor habits, and thus offer new potentialities. In the last part of the thesis, a practical approach is offered, whereby the various works created during the doctoral research are presented, along with the results of a behaviourist study. This thesis hopes to offer the premise of a new aesthetics by exposing the process of appropriation of immersive/interactive installations and by demonstrating that, in certain cases, such installations can propose a singular experience, a selfexperience, a new active and aesthetic state of being

Testo completoThe goal of this study was to explore and develop a statistically derived typology of arsons and arsonists (serial and non-serial) from the Province of Quebec, for practical as much as scientific concerns. By collecting sociodemographic, criminals, and psychological information on the crime and the individual, it was possible to find, through latent class analyses (LCA), the most targeted crime scenes and main motivations to commit an arson. To do so, files from across the Province were selected and coded. In total, 48 files were analyzed, allowing to create a database of 245 arsons committed by 59 arsonists. In order to select those files, a coding sheet was sent to police services across the Province of Quebec. In line with scientific and practical gaps, the coding sheet was divided in three main sections: 1) sociodemographic characteristics; 2) information regarding the arson; 3) arsonists’ psychological profile information. Results show that, among the four main targeted crime scenes, public places were those mostly targeted by Quebecer arsonists. Moreover, analyses show six main motivations to commit arson. The identified crime scene and the identified motivation profiles were then combined, using bivariate analyses, to see how the arsonists’ motivation varied based on the targeted crime scenes. Results show that arsonists with profit or retaliation intentions are susceptible to target residential areas or vehicles. Globally, analyses highlighted that arson and arsonist profiles are still unknown in Quebec and, by knowing the most targeted crime scene and arsonist motivations, it is possible to enhances the investigators’ comprehension in arson cases, as much as guide them in terms of suspects’ prioritisation and identification. Keywords: arson, arsonists, serial arson, serial arsonists, crime scene, motivation, profiling, suspect prioritisation, crime prevention, latent class analysis.

Testo completoTaking into account of the user's behaviour in interactive applications, including human users, appears evident to develop a fast decision-making model and adapted to the situation. It consists in extracting conclusions relating to user's behaviour and provides in a real time personalized way adequate activities, keeping in mind the expert's advice. Within this framework, we have contributed to solve the adaptive execution problem by observing and analysing of behaviour. The first part concerns behaviour analysis. We thus defined a formalism based on observation of user's behaviour. It concerns the observation carried out on the explicit and implicit actions of user. User's explicit actions are recorded with the help of: mouse, touch screen and keyboard. User's implicit actions concern the facial expressions. The second part is about execution control models that take into account users behaviours. We have defined a model based on the case-based reasoning that allows the generation of activities corresponding to the user's profile, his needs and behaviour. Our strategy of control consists in launching an episode of reasoning each time that a particular behaviour is detected. The application context relates to interactive software for autistic children. This application's framework represents the characteristic of a user-adapted and interactive implementation appropriate for each autistic child's behaviour. It constitutes a framework of application and the validation of our contribution

Testo completoMisumena vatia is assumed for more than a century to adapt its colouration to the colour of its substrate in order to decrease the risk of being detected by prey and predators. However, a discrepancy exists between the large quantity of works on its ecology, its fame as an expert of camouflage and the empirical knowledge about its cryspis and colour change mechanisms. The aim of this thesis was therefore to study crypsis from a community sensory perspective, using an approach combing physiology, behaviour and colour vision models. We showed that if M. vatia was undetectable at long distance through achromatic vision, the chromatic contrast value is quite dependent of both substrates and receiver identities. Electrophysiological recordings and behavioural choices all concur to show that M. vatia is able to see colours. Spiderlings use this ability for making choices among coloured backgrounds diminishing its conspicuousness to potential prey. Finally, the results of this thesis are discussed in an evolutionary and physiological context

Testo completoThe aim of this work is the delaited study of the relationships between alcohol consumption and emotional reactivity in the rat and the search for the molecular genetic mechanisms influencing these phenotypes. The High-Ethanol Preferring line of rats (HEP) is characterized by high voluntary consumption of alcohol. A QTL search identified a locus on chromosome 4 linked to the consumption of a 5% alcohol solution offered as a free choice with water (names Coet5). In the same region, was found a QTL related to the reinforcement properties of saccharin and emotional reactivity. In order to confirm and analyse the influence of this QTL, two groups of animals contrasted for their genotypes at Coet5 were selected on the basis of genetic markers. To study more precisely the location of Coet5, we developed a congenic line. These results confirm the influence of this locus on alcohol intake and emotional reactivity traits, and suggest a pleiotropic effect of the gene(s) involved

Testo completoAs available therapies to treat cognitive disorders show their limits, there is a crucial need for new therapeutical strategies. 5-HT6 receptors (5-HT6R) represent an interesting target, as shown by the growing body of literature demonstrating the promnesiant effects of 5-HT6R antagonists. Beneficial effects have been observed in pre-clinical and clinical studies, but the underlying mechanisms remain poorly understood. Through behavioural approaches in mice, we report herein a complex interplay between 5-HT6R and the cholinergic system, which depends on the memory system considered. Furthermore, we demonstrated that chronic 5-HT6R antagonist administration is safe and efficient on memory, even at very low doses. Immunohistochemical study revealed that the localization of 5-HT6R could participate in the modulation of information input during learning. Immunoblotting and qPCR showed that chronic 5-HT6R blockade modified their expression, notably by a decrease in the neocortex. Chronic 5-HT6R blockade also influenced the dopaminergic transmission in the striatum, a key region for memory, and modulated neuronal plasticity by increasing hippocampal cell survival. These effects certainly represent key features in the promnesiant effects displayed by 5-HT6R antagonists. These results highlight the potential of 5-HT6R as new therapeutic targets in the treatment of memory disorders associated with physiological and pathological ageing

Testo completoAlzheimer didease (AD) is characterized by memory loss and cerebral lesions, namely neurofibrillary tangles and senile plaques. The latter contains amyloid-beta deposits derived from clevages of the amyloid precursor protein (APP), encoded by the APP gene. Studies of the dominant autosomal forms of AD permitted the discovery of several genetic mutations and the generation of animal models. The aim of our work is to charactezise the behavior and the neurochemistry of two mouse models. , in order to highlight the APP transgene effects alone and in relation with amyloid plaques. The first model overexpresses the human C99-terminal fragment of APP, while the second expresses the APP gene with the Swedish mutation. More precisely, exploratory activity, anxiety, motor coordination, and spatial learning were analysed. In cerebral tissue, energetic metabolism, oxidative stress, and cholinergic innervation, corresponding to AD-like affected markers were examined by means of cytochrome oxidase, nitric oxide synthase, and acetylcholinesterase activity, respectively. The data revealed alterations representative of early stages and pre-degeneretive forms of AD. Indded, in these two models, we reported abnormalities of exploratory behavior and spatial learning impairment, together with changes in cerebral metabolism, particularly in regions without plaques. Nevertheless, we observed specific neurological signs in the APP Swedish mutation, namely myoclonic and epileptic seizures. Moreover, cholinergic innervation was affected in the functional loop existing between basal forebrain cholinergic neuronsand neocortex of hippocampus, a possible explanation of some bahavioral results. Therefore, overexpressed APP transgenes may be sufficient to cause behavioural and neurochemical deficits similar to those found in AD, via cellular oxidative stress and excitotoxic mechanisms

Testo completoThe study and the understanding of human behavior has become one of the major concerns for various reasons in different sectors of activity. This need to understand the habits of people led several big firms towards the use of videos surveillance for analyzing and interpreting behaviors. These reasons led to the emergence of research aimed at automating these procedures. As a result, the study of human behavior has become the main subject of several researches in the field of computer vision. Thus, a variety of behavior analysis solutions based on artificial intelligence emerged.In this work, our objective is the proposal of a solution that enable the simultaneous track of several individuals in a multi-camera network in order to reconstruct their trajectories in the context of behavioral analysis. For this, we have proposed a system that is made of three main modules and a management module. The first module is a counting module to measure entries. The second module is a mono-camera tracking system that is based on the use of particle filtering to track individuals independently in each camera. The third module is a re-identification module which is based on the selection of salient regions for each individual. It enables the association of the individuals that are detected in the different cameras. The last module which is the management module is based on the use of ontologies for interpreting trajectories. This module is designed to create semantic trajectories from raw trajectories obtained previously

Testo completoNear every turbo alternator machine, voltage and frequency of the electric power network are fixed by speed and voltage controllers. These two separated controllers can not efficiently take into account links between voltage and frequency, when these two quantities are bound by physical laws that govern machine behaviour. We established a representative model of the "turbine-alternator-finite network" system, in order to make significant simulations in opened loop and in closed loop to better estimate existing controller limits. This model allowed the study of the system's own non-linearities and voltage frequency bounds, through opened loop response not available with the real system. By linearising the full model, we built a state variable model of the turbo alternator-finite network system. This model extends to finite network the state variable representation on infinite network made by EDF company. This state variable model was used for synthesis of new control strategies, taking into account voltage frequency bounds and non-linearities, which are characteristics of the system. Our study led to a full simulation software and covered a voltage and frequency decoupling strategy with full tests of robustness and validity
