In the semi-arid Mediterranean region, and more particularly in the Maghreb, the increased pressures on water resources (climate change, growing competition between users) are recognized as major issues. Rational water management is one of the challenges facing the Urban Grouping of Constantine (GUC) in northeast Algeria. Its water resources are renewable but limited, while the demand is constantly growing under the dual effect of population growth and increasing per capita needs. The Group is composed of five municipalities (Constantine, El Khroub, Ain Smara, Didouche Mourad and Hamma Bouziane) with a population of nearly 884,000 inhabitants in 2015, expected to reach 1.2 million inhabitants in 2030 and 1.8 million inhabitants in 2050 according to projections made by WEAP The mobilized resources provide a volume of drinking water supply of 117 million m3 of which 78 % is surface water and the rest is of underground origin. However, the volume billed is reduced to 47.3 million m3, a difference of -51% compared to the overall volume of water distributed (97 million m3). The rate of connection to the water supply network is over 80 %. The number of water leaks detected on the network has experienced a relative decline in 2015, the result of rehabilitation operations carried out at the level of urban centers. For the same year, SEACO statistics show that the hourly duration of water service increased in the GUC municipalities, reaching 18.3 hours per day and 74 % of households benefited from continuous distribution (24 hours per day). This improvement is mainly due to the increase in resources mobilized from the Beni Haroun dam. However, the spatial inequality in the supply of the GUC agglomerations remains effective. It is attributable both to the availability of the resource and to the management of hydraulic infrastructures. Also, satisfaction by mobilizable volumes may not be guaranteed in the long term, given sectoral competition, climatic hazards and the poor protection of resources. Modeling using WEAP (Water Evaluation and Planning System) has been performed. It is applied to evaluate and analyze the existing and expected resourcerequirement balance by 2050, according to future water resource management scenarios,
taking into account different exploitation policies and factors that may affect demand.

The experimental way was largely explored during last decades and it was the subject of our study.
On the experimental level, the testing methods most frequently used for the validation of the models of behavior comprise primarily oedometric tests compression and shear tests to the traditional triaxial apparatus.
These tests constitute the basic tools for the knowledge of the behavior of clays and make it possible to follow ways of constraints or deformations simulating the real behavior of the works in place. In parallel, of the testing methods in situ (penetrometers, pressiometers, etc.) were developed in order to characterize the best possible behavior of clays in place. Although these tests have the advantage of being inexpensive and rapids to be carried out, of or their relative success, the results obtained difficult with is interpreted in term of laws of behavior of the grounds, because the ways of total or effective constraints follow-ups in these tests are badly known, the boundary conditions space are impossible to define, the conditions of drainage or are not known generally little, etc. These difficulties pose serious problems with the good in situ test schedule –and their exploitation, which allowed privileged people the laboratory, tests (oedometers, triaxial).
The objective of this study is the experimental characterization of the model of behavior of natural clays several sites of the area of Constantine, the test routine A made it possible to determine the form of the surface of load, which is controlled by the constraint of preconsolidation, it has an appreciably elliptic form inclined on the line µ O or Ko On the level of the laboratory tests we had interesting results concerning the strength parameters it and φ ', the param beings of deformations and the coefficient of earth pressure at rest Ko.
These results are comparable with those obtained on other natural clays which have the same behavior and the same shape of the curve of absolute limit (Jausseaume, Azizi, 1991), the clay of Guiche (valley of Adour) (khemissa, J-P.Magnan, H.Josseaume), the clay of Saint-Alban (Leroueil and Al, 1979).Diplôme : Doctorat en sciences En ligne : ../theses/gcivil/BEL5886.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=5669 Caractérisation des formations argileuses de la région de Constantine.

The subject of this thesis is the 2D numerical modeling of an SiGe HBT (Heterojunction Bipolar Transistor) using the SILVACO-TCAD software. A simulation of the technological process was first adapted and carried out, and then we were interested in the electrical simulation. For this, we considered three electrical models: the DDM model (Drift Diffusion Model), the isothermal Energy Balance model (EB) and the Non-isothermal Energy Balance model (NEB). Due to the carrier’s overshoot and the non-isothermal effects present in the considered HBT, the NEB model was retained. In addition, the HBT SiGe produced in advanced technologies uses the Superficial and Deep Trenches Isolation (STI and DTI) as isolation between the different devices existing on the same chip. We have studied their impacts on the self-heating phenomenon and the static and dynamic performance of TBH SiGe. The results obtained showed that the self-heating phenomenon is accentuated in this case. In order to improve the electrical and thermal performance of the device, we were interested in analyzing other technological variants.Thus,we start by observing the beneficial effect of the ‘scaling’and the type of Si or SOI (Silicon On Insulate) substrate on the performances of the SiGe heterojunction bipolar transistor. Their effect is very significant on the improvement of electrical performances but an increase of the lattice temperature of the device is also observed. A technological solution to reduce this self-heating phenomenon is ""multi-emitter"" or multi-finger technology. An analysis of this solution was carried out and optimized and its benefit proven.
