The electrical arc faults are the cause of electrical home fire. Detecting them is an improvement of domestic electrical safety. The thesis contribution focuses on the problem of the electrical arc fault identification and detection in the domestic low voltage network. In this thesis, the first research objective is the modeling of a domestic electrical network. The aim of the modeling is to recreate graphically the loads and the topology of the real domestic electrical network associated with a series electrical arc fault. The modeling is made on the AC voltage source, domestic loads, arc fault model and a block of current and voltage analysis to control a circuit breaker. The second research objective is the development of a robust method for detecting arcing fault. Four detecting methods were developed as part of this thesis; they are based on the current analysis of frequency and time characteristics. All methods generate information whose amplitude tends to increase in the presence of an electric arc. However, the non-deterministic and random feature of the signals produced by the electrical arc fault as well as the large number and variability of loads and the disturbances which they introduce make the arc detection very difficult. All the studies consistently are composed of a comparison between the normal operation and arc fault signals. The result has resulted in a combined approach of some methodologies and a simple decision model based on a threshold. A prototype which contains a part of the algorithm was shown the feasibility of a circuit in real time

In the general context of biodiversity erosion, two forest bird species occurring in the French Jura massif, the Capercaillie (Tetrao urogallus) and the Hazel Grouse (Bonasa bonasia), are threatened by habitat loss and fragmentation at the regional scale. In particular, intensive beech regeneration patches extension in the Jura massif is leading to the transformation of the understory cover, once suitable with bilberry and herbaceous vegetation, to closed unfavorable habitat. The fate of those two emblematic species is depending for the first on future management actions and for the second on a better knowledge of the species population’s dynamics and occurrences. In particular, the cutting of the beech regeneration patches is one of the efficient management actions undertaken to restore the habitat. However, management actions and surveys are money and time consuming due to the large area that need to be covered. The opportunity to use two Light Detection and Ranging (LiDAR) datasets covering a major part of the distribution of the two species in the Jura massif initiated the phD project, with the objective to support managers in their decisions and actions by the creation of adapted distribution predicted maps using Species Distribution Models (SDMs) (Hazel Grouse, Capercaillie and beech regeneration). The realization of this objective is depending on the reliability of the models produced and on the capacity of the researcher to transfer the results to managers who are not familiar with modeling methods. In a first step, the choice of the appropriate modeling method regarding the datasets characteristics and the objectives was investigated (sampling bias correction, scales, and algorithms). In addition, the use of object-oriented LiDAR predictors (trees and gaps) pertinent from both species and managers point of view to facilitate the results transfer was tested. The results obtained were used to create appropriate multi-scale SDMs and to predict distribution maps for both target species, demonstrating the capacity of LiDAR to represent vegetation structures that influence the targeted forest bird species occurrences. Models at a fine scale were also created to map the beech regeneration distribution in the Jura massif

The objective of this thesis is to study an integrated energy system in the building envelope for fresh air preheating. The originality of the work is that the wall is equipped with phase-change material (MCP) packed into briquettes. The main role ofthe wall is to preheat the fresh air (coming from outside) by destocking the solar energy captured in sunny periods.Our study consists of two phases, an experimental phase and a numerical one. The experimental phase involves a series of tests that allow studying the thermal behaviour of the system under thermal stress. These tests were done in laboratory through a prototype of the wall which is instrumented and installed between two airconditioned cells.The purpose of the numerical phase is to develop a one-dimensional model to simulate the thermal behaviour of the wall and especially that of MCP. This model has been validated by comparing numerical results with those obtained experimentally. To model the phase changing we used the thermophysical parameters of the same material obtained by experimental characterization conducted in our laboratory.We used a variable capacity method whose principle is to vary the heat capacity as a function of temperature in order to simulate the phase changing of the wall. The last part of the numerical work is the exploitation of the model, the aim is to determine the optimal configuration of the wall that provides maximum energy savings. Dynamic simulation of the system was performed using the TRNSYS. This one is equipped with weather files which allow carrying out heat balances and the estimation of the system efficiency for various climates

The Humboldt Current System is the most productive oceanic system in terms of fish biomass. Its main species, the Peruvian anchovy (Engraulis ringens) and sardine (Sardinops sagax), have known important historical variations of their stocks, a particularity which has questioned oceanographers for many years. The goal of the present work is to implement an eulerian approach focusing on the early life stages of peruvian anchovy and sardine, in order to study the influence of environmental parameters and climate variability on population dynamics and stocks variability. The model is adapted from the "Spatial Eulerian Ecosystem and Population Dynamic Model" SEAPODYM, initially developed for large pelagic fishes at ocean basin scale. It uses the outputs of a regional ROMS-PISCES coupled physical-biogeochemical model as environmental forcing. In order to constrain model parameters, we developed a data assimilation framework using a unique dataset of eggs and larvae abundances, collected by the Instituto del Mar del Peru (IMARPE) in the HCS waters over the last 40 years. This framework allows to test different mechanisms proposed to control fish spawning habitat and larval recruitment: optimal temperature, prey abundance, trade-off between preys and predators, and influence of currents on retention and dispersion. We show that the combination of a few simple concepts can reasonably explain the overall spatial distribution of eggs and larvae and the interannual variability, but the current description is still not sufficient to explain the observed abundance seasonality in coastal areas
