The thermalmechanical safety analysis of a lowenriched uranium foil based annular target for molybdenum-99 production will be presented. The target constitutes a low enriched uranium foil sandwiched between two concentric aluminum tubes to form a composite cylindrical structure. A threestep numerical model is built using the commercial finite element code Abaqus FEA to simulate the assembly pro...

This paper deals with the theoretical investigation of the thermal instability of a thin layer of electrically conducting micropolar rotating fluid, heated from below in the presence of uniform vertical magnetic field in porous medium. A dispersion relation is obtained for a flat fluid layer, contained between two free boundaries using a linear stability analysis theory, and normal mode analysi...

Today, power electronic reliability is a main subject of interest for many companies and laboratories. The main process leading to the IGBT failure is the cycling thermal stress. Indeed the current flow induce local heating and then mechanical stress. This paper deals with electro thermal stress under steady and transient current states. The main objective is to test bonded wires with active cu...

This paper is concerned with the problem of synchronization for complex dynamic networks with state and coupling time-delays. Therefore, larger class and more complicated complex dynamic networks can be considered for the synchronization problem. Based on the Lyapunov-Krasovskii functional, a delay-independent criterion is obtained and formulated in the form of linear matrix inequalities (LMIs)...

Decomposition has proved an effective strategy in planning, with one decomposition-based planner, SGPLAN, exhibiting strong performance in the last two IPCs. By decomposing planning problems into several loosely coupled subproblems, themselves planning problems, a planner can be used to solve each of the subproblems individually. The subplans can then be combined to form a solution to the origi...
