Повний текст джерелаThis work studies biological in silico networks. It assess the question of integration, formalism and model of biological networks and subnetworks. First, an integration tool called Cyclone was developed to simplify the access and analyse biological information of the Biocyc database. Then, a graph model framework to analyse heterogeneous networks, MIB (for Biological Interaction Model) is presented. Finally, on one hand, these methods were used to study how subnetworks were linked together and to study network motifs in larger networks, and on the other hand, to study and model the metabolic pathway of galactose in yeast (Saccharomyces cerevisiae) that includes a heterogeneous feedback loop made of protein-protein interaction and transcriptional regulation

Повний текст джерелаThere are usually two opposite points of view for the modelling of complex systems. First, microscopical models aim at reproducing precisely the behavior of each entity of the system. In general, their great number is a major obstacle both to simulate the model in a reasonable time and to identify global behaviors. By contrast, the phenomenological approach allows the construction of efficient models from a macroscopic point of view as a superposition of phenomena. A drawback is that we often have to set empirical parameters in these descriptive models. To respond to this problem, we want to make joint use of different levels of description and to use microscopical simulations to feed incomplete macroscopical models.We would then obtain enhanced descriptive simulations with the precision of microscopical models in this way. To this end, we propose a redundant multiscale architecture which is based on the co-simulation methodology in order to generalize the redundant multiscale approach. We suggest two specific co-simulation strategies to guide a macroscopical simulation.The first one consists in dynamically and explicitly estimating critical parameters of a macroscopical model thanks to a dedicated microscopical simulator The second one allows to implicitly determine a full set of dependant parameters on the basis of an output shared by the different levels of description. Then we apply our works to the effective problem of the design offshore structures for arctic conditions. We first describe the implementation of an ice-structure simulation tool by means of a phenomenological and multi-model approach. In a second phase, we show the benefits of our co-simulation strategies to improve the precision of hydrodynamics simulations on the one hand, and on the other to pilot a more macroscopical model for the purpose of fast prototyping

Повний текст джерелаIn This work we present an agent-based approach for coupling models in the context of complex spatial systems. The main idea of our approach called Coupling4Modeling is the use of the space as a medium of interactions between the coupling agents to allow them to co-exist and interact according to a set of rules that govern these interactions. By playing the role of coupling factor, space allows coupling agents to exchange data and to observe the results of pragmatic coupling of different models constituting the studied spatial complex sys-tem. This approach consisting in a methodology and an agent-oriented metamodel of coupling. Our metamodel is based on an organizational (AGRE) with holonic architecture that takes into consideration the specificity, autonomy and the calculation scale of each model. This notion of holon allows us to manage the heterogeneity of formalisms and spatio-temporal scales of models. In fact, spatial heterogeneity is managed by the decomposition of the collector and the interpreter agents until reaching the desired level of abstraction. These agents can move from one level to another by adapting the spatial scale of the space to the spatial scale of the model through conversion functions. The temporal heterogeneity is managed by a time agent that will calculate the future date in the execution of the model and a scheduler agent that will schedule these dates following the time scale of the simulation. We take the urban system of Metouia (Tunisia) as an example of spatial complex system, to study with details and to test our coupling4modeling approach. The main goal is to meet the needs of urbanists in terms of decision support in urban planning and to test our coupling approach coupling4modeling

Повний текст джерелаWithin a behavioral approach and given the complexity of financial markets, the aim of this thesis is to examine the extent to which directed networks that governs the interaction among investors as well as their mimicking behavior influence their anticipations and the price dynamics. We propose an artificial asset market populated by chartists and fundamentalists who are allowed to switch from one trading strategy to the other according to their relative performances. Firstly, we study a fully connected network to test for a global interaction. We find that our benchmark model accounts for the emergence of excess volatility of asset prices when chartists dominate the market. Secondly, we restrict our focus to local interactions between investors. We generate a family of network structures that spans regular network, small world network and random network. Thirdly, we introduce a new model that allows us to control (1) the direction of the rewiring process of the links; (2) the randomness of the network; and (3) the asymmetry in its degree distribution by assuming that there are two classes of agents: stars and non-stars. We show that unlike the degree of the randomness of the network, the asymmetry in the degree distribution produces opposite effects depending on whether the network is outward or inward rewired. Finally, we address the question as to how this analysis can be used to produce realistic market dynamics. We find that the presence of a mimicking threshold with a high reaction coefficient provides a better approximation to the characteristics of the distribution of real returns and reproduces the most important stylized facts observed in financial time series

Повний текст джерелаThe development of sustainable smart cities requires the deployment of Information and Communication Technology (ICT) to ensure better services and available information at any time and everywhere. As IoT devices become more powerful and low-cost, the implementation of an extensive sensor network for an urban context can be expensive. This thesis proposes a technique for estimating missing environmental information in large scale environments. Our technique enables providing information whereas devices are not available for an area of the environment not covered by sensing devices. The contribution of our proposal is summarized in the following points: * limiting the number of sensing devices to be deployed in an urban environment; * the exploitation of heterogeneous data acquired from intermittent devices; * real-time processing of information; * self-calibration of the system. Our proposal uses the Adaptive Multi-Agent System (AMAS) approach to solve the problem of information unavailability. In this approach, an exception is considered as a Non-Cooperative Situation (NCS) that has to be solved locally and cooperatively. HybridIoT exploits both homogeneous (information of the same type) and heterogeneous information (information of different types or units) acquired from some available sensing device to provide accurate estimates in the point of the environment where a sensing device is not available. The proposed technique enables estimating accurate environmental information under conditions of uncertainty arising from the urban application context in which the project is situated, and which have not been explored by the state-of-the-art solutions: * openness: sensors can enter or leave the system at any time without the need for any reconfiguration; * large scale: the system can be deployed in a large, urban context and ensure correct operation with a significative number of devices; * heterogeneity: the system handles different types of information without any a priori configuration. Our proposal does not require any input parameters or reconfiguration. The system can operate in open, dynamic environments such as cities, where a large number of sensing devices can appear or disappear at any time and without any prior notification. We carried out different experiments to compare the obtained results to various standard techniques to assess the validity of our proposal. We also developed a pipeline of standard techniques to produce baseline results that will be compared to those obtained by our multi-agent proposal

Повний текст джерелаThis thesis is devoted to the study of price formation on financial markets, in particular when these are composed of a large number of agents. We start by the empirical study of an emergent market -- the bitcoin -- in order to better understand how individual actions impact prices -- a phenomenon known as « market impact ». We then develop a theoretical model based on the concept of heterogeneous agents, that allows to reproduce the empirical observations of a concave impact in a market that remains non-manipulable. The heterogeneous agents framework allows us to revisit the concepts of supply and demand in a dynamic context, to better understand how the choice of a particular market mechanism can impact liquidity, and to lay some grounds for a realistic market simulator. By studying several bubbles and crashes that happened on the bitcoin market, we finally show how relevant microstructure effects can be, in particular for understanding the occurrence of extreme phenomena
