Texto completoThis thesis aims to uncover the underlyingcausality structure of financial markets by focusing onthe inference of investor causal networks at multipletimescales in two trader-resolved datasets.The first part of this thesis is devoted to the causal strengthof Hawkes processes. These processes describe in a clearlycausal way how the activity rate of e.g. an investor dependson his past activity rate; its multivariate version alsomakes it possible to include the interactions between theagents, at all time scales. The main result of this part isthat the classical MLE estimation of the process parametersdoes not vary significantly if the arrow of time is reversedin the univariate and symmetric multivariate case.This means that blindly trusting univariate and symmetricmultivariate Hawkes processes to infer causality from datais problematic. In addition, we find a dependency betweenthe level of causality in the process and its endogeneity.For long time series of synthetic data, one can discriminatebetween the forward and backward arrows of time byperforming rigorous statistical tests on the processes, butfor empirical data the situation is much more ambiguous,as it is entirely possible to find a better Hawkes process fitwhen time runs backwards compared to forwards.Asymmetric Hawkes processes do not suffer from veryweak causality. Fitting them to the individual traders’ actionsfound in our datasets is unfortunately not very successfulfor two reasons. We carefully checked that tradersactions in both datasets are highly non-stationary, andthat local stationarity cannot be assumed to hold as thereis simply not enough data, even if each dataset containsabout one million trades. This is also compounded by thefact that Hawkes processes encode the pairwise influenceof traders for all timescales simultaneously.In order to alleviate this problem, the second part ofthis thesis focuses on causality between specific pairs oftimescales. Further filtering is achieved by reducing theeffective number of investors; Statistically Validated Networksare applied to cluster investors into groups basedon the statistically high synchronisation of their actions(buy, sell or neutral) in time intervals of a given timescale.This part then generalizes single-timescale lead-lag SVNsto lead-lag networks between two timescales and introducesthree slightly different methodsThese methods make it possible to characterize causalityin a novel way. We are able to compare the time reversalasymmetry of trader activity and that of price volatility,and conclude that the causal structure of trader activity isconsiderably more complex than that of the volatility for agiven category of traders. Expectedly, institutional traders,whose impact on prices is much larger than that of retailclients, have a causality structure that is closer to that ofvolatility. This is because volatility, being a macroscopicquantity, aggregates the behaviour of all types of traders,thereby hiding the causality structure of minor players
Le, Bon Caroline. "Le capital de mode : un nouveau concept pour comprendre et expliquer le comportement du consommateur de produits de mode". Thesis, Aix-Marseille 3, 2011. http://www.theses.fr/2011AIX32026.
Texto completoFashion transcends domains, applies to almost any kind of product and concerns many people. The loyalty towards fashion products raises questions about why and how products appeal to consumers, despite their constantly varying attributes. Furthermore, little is known about how fashion trends may induce people to stay loyal to fashion products. We are not aware of any other approach that explains consumer behavior on the basis of fashion value per se, that is, that a fashion product is of interest because it is explicitly perceived as a fashion item. We propose a new explanation for consumers’ interest in and loyalty to fashion products. Extending the concept of consumer-based brand equity (Keller, 1993), we propose that consumer-based fashion equity may account for the role that fashion plays, in determining consumers’ loyalty—similar to the way brand equity explains why high equity brands appeal more to consumers than do low equity ones. We introduce the concept of fashion equity to account for the value that fashion adds to products. The exploratory study conducted with followers confirms the values added by fashion to product and the results of our analysis demonstrates that attachment is a mediator in the relationships fashion equity-attachment-loyalty for fashion clothe and mobile phone. Therefore, these values contribute to the development of fashion attachment and fashion loyalty. Our research suggests an explanation of loyalty towards fashion thanks to fashion equity

Texto completoThis study argues that the merger predilections of many of the largest us and eu manufacturing firms may well have negative effects on their competitiveness vis-a-vis their japanese rivals. It first demonstrates that mergers and acquisitions are much more common among us and eu than among japanese firms. An extensive review of the literature subsequently confirms that mergers and acquisitions do not generally generate extra profitability, productive efficiency, market share growth and/or innovativeness. While the static welfare losses of such merger predilections may not be dramatic, they may lead to substantial dynamic losses when merger-prone firms need to compete with firms which instead focus on equipment investment and investments in r&d. The study shows that japanese firms have outperformed us and eu firms in terms of such investments during the 1980s so that it appears that the market share losses that western firms experienced during that same period have been caused by their merger predilections. These findings raise both theoretical and policy questions. On the theoretical side, the study demonstrates that strategic interdependence, which is the typical setting in which large firms operate, may encourage minimax regret rather than efficient choice behaviour. A single major merger may then trigger a bandwagon of imitative and defensive mergers. On the policy side, it is consequently argued that competition policies should test for the productive and dynamic rather than allocative efficiency effects of mergers. Industrial policies should focus on the fostering of innovative small and medium sized firms rather than on encouraging the predilections of large firms. The study suggests that the development of networks of local virtual stock exchanges may be an effective instrument in that respect

Texto completoNowadays, robots have become increasingly important to investigate hazardous and dangerous environments. A group of collaborating robots can often deal with tasks that are difficult, or even impossible, to be accomplished by a single robot. Multiple robots working in a cooperative manner is called as a Multi-Agent System (MAS). The interaction between agents to achieve a global task is a key in cooperative control. Cooperative control of MASs poses significant theoretical and practical challenges. One of the fundamental topics in cooperative control is the consensus where the objective is to design control protocols between agents to achieve a state agreement. This thesis improves the navigation scheme for MASs, while taking into account some practical constraints (robot model and temporal constraints) in the design of cooperative controllers for each agent, in a fully decentralized way. In this thesis, two directions are investigated. On one hand, the convergence rate is an important performance specification to design the controller for a dynamical system. As an important performance measure for the coordination control of MASs, fast convergence is always pursued to achieve better performance and robustness. Most of the existing consensus algorithms focus on asymptotic convergence, where the settling time is infinite. However, many applications require a high speed convergence generally characterized by a finite-time control strategy. Moreover, finite-time control allows some advantageous properties but the settling time depend on the initial states of agents. The objective here is to design a fixed-time leader-follower consensus protocol for MASs described in continuous-time. This problem is studied using the powerful theory of fixed-time stabilization, which guarantee that the settling time is upper bounded regardless to the initial conditions. Sliding mode controllers and sliding mode observers are designed for each agent to solve the fixed-time consensus tracking problem when the leader is dynamic. On the other hand, compared with continuous-time systems, consensus problem in a discrete-time framework is more suitable for practical applications due to the limitation of computational resources for each agent. Model Predictive Control (MPC) has the ability to handle control and state constraints for discrete-time systems. In this thesis, this method is applied to deal with the consensus problem in discrete-time by letting each agent to solve, at each step, a constrained optimal control problem involving only the state of neighboring agents. The tracking performances are also improved in this thesis by adding new terms in the classical MPC technique. The proposed controllers will be simulated and implemented on a team of multiple Mini-Lab Enova Robots using ROS (Robotic Operating System) which is an operating system for mobile robots. ROS provides not only standard operating system services but also high-level functionalities. In this thesis, some solutions corresponding to problem of connection between multiple mobile robots in a decentralized way for a wireless robotic network, of tuning of the sampling periods and control parameters are also discussed

Texto completoInteractions in teamwork and their efficiency are based on a hierarchical system including verticale dyads. This research studies leadership through the social roles link to the hierarchical status of the vertical dyad (i.e., leader for the chief and follower for the subordinate).The influence of follower on leader and leadership is increasingly considered. However, the follower’s behaviors are still unexplored. This multidisciplinary doctoral work (i.e., psychology and affective computing) tries to highlight the influence of follower’s behavior on the leader, and the underlying process of this influence.To do so, we used the follower’s nonverbal behaviors (CNV) as the social clues that can influence the leader and his behaviors. The principles of social cognition are applied in this thesis to study the cognitive evaluation made by the leader. We worked on the activation of the caracteristics used to categorize followers, the implicit followership theories (IFTs).The study of the cognitive evaluation made by the leader comes we multiple issues, including methological ones. Thus, a preliminary work of translation and validation of a scale evaluating the IFTs was realized. The first exploratory study used images of virtual agents displaying CNV that could explicitly activate leaders’ IFTs. We complete these result through an analysis of a corpus of videos filming medical teams’ training. This study allowed us to observe dynamic CNV that could influence the perception of followership. In a third study, we implemented the CNV of the two previous studies in a virtual agent. Medical leaders had to interact with it, and implicit activation of IFTs was collected using a Go / No Go protocol. Finally, using a quantitative approach, we studied the influence of cognitive evaluation of the leader on his leadership behaviors.Results suggest that some caracteristics displayed in CNV (i.e., dominance and support) can activate the leaders’ IFTs. Moreover, the cognitive evaluation of the leader seems to influence his leadership behaviors.We will discuss the results and explain the scientifical and pédagogical contributions of this thesis. We will analyse our problematic through multiple angles, including the epistemologycal point of view allowing the study of IFTs, and the use of virtual agents in the research field of categorization process. The practical application of the doctoral work is the implementation of CNV in virtual subordinates for the deployement of a serious game for medical team leader

Texto completoThe objective of this thesis is to develop and study mathematical models of economical exchanges between energy suppliers and consumers, using demand-side management. On one hand, the suppliers offer time-of-use electricity prices. On the other hand, energy consumers decide on their energy demand schedule, minimizing their electricity bill and the inconvenience due to schedule changes. This problem structure gives rise to bilevel optimization problems.Three kinds of models are studied. First, single-leader single-follower problems modeling the interaction between an energy supplier and a smart grid operator. In this first approach, the level of details is very high on the follower’s side, and notably includes a stochastic treatment of distributed generation. Second, a multi-leader multi-follower problem is studied from the point of view of the best response of one of the suppliers. Aggregators are included in the lower level. Two new resolution methods based on a selection of Nash equilibriums at the lower level are proposed. In the third and final part, the focus is on the evaluation of noncooperative equilibriums for this multi-leader multi-follower problem.All the problems have been studied both from a theoretical and numerical point of view

Texto completoDuring the certification process of a turbo engine, the engine manufacturer has to demonstrate that the loss of a rotor blade does not lead to the "knocking-off" phenomenon, in other words to the cascading failure of the successive blades. Generally, this demonstration is carried out through a costly rig test driving to the partial destruction of the engine. Thanks to the improvement of computational resources, it is now possible to simulate the transient response of the structure subjected to this complex loading. The knowledge of material behavior turns out to be the essential starting point for the simulation. However, only a few studies have been published on the dynamic behavior of nickel-based single crystal superalloys at high temperature reaching 1000°C. With a view to efficiently predicting the consequences of impacts on turbine blades, experimental and numerical works have been conducted on a single crystal frequently used by Turbomeca. High-temperature dynamic compressive tests on Split Hopkinson Pressure Bars (SHPB) have enabled to estimate the material plasticity level and hardening, depending on the crystal orientation, strain rate and temperature. The parameters of a viscoplastic anisotropic law have been identified to effectively model the MC2 macroscopic behavior under highly intense and multiaxial loading. At Safran Snecma Villaroche, ballistic tests have been undertaken on both single crystal plates and blades under high temperatures. In order to consider the fragmentation of profiles in blade-off simulations, a plastic strain criterion depending on stress triaxiality has been calibrated and validated by comparison with the impacts on blades. Post-mortem digital images correlation measurements and high-speed camera recordings have confirmed these simulations. Using LS-Dyna solver, a blade-off modeling strategy has been created and applied to an actual blade-off industrial case. Finally, a rotordynamics approach has been developed and validated with the aim of separately analyzing the primary damage, caused by direct impacts on the first following blades, and the secondary damage due to the effects of unbalance on a flexible rotor
