In video stream transmission, one often proposes to solve the problem of the heterogeneity of the receivers by dividing the stream into several cumulative layers distributed over multicast transmission. A dynamic adaptation by the source of the number and size of layer bit-rates to the set of its receivers allows a better usage of the network resources. Efficient algorithms have been designed to do this adaptation. However, the encoding of a video stream in layers incurs an overhead relatively to the single-layer encoding of the same stream. A too naive modeling of this overhead causes a suboptimal allocation of bit-rate. We propose an improvement of the layer bit-rate adaptation algorithm by dynamic programming to take a finer overhead model and other encoder constraints into account. To this end, we introduce a more general overhead model. As our algorithm is of high complexity, we also present a heuristic allowing to find quickly a solution which is near the optimum and we test this heuristic by simulations based on our model.

Wrought 7075 aluminium alloy functional parts with complex geometry are mostly shaped by machining. For a mass production, the machining cost can be reduced by shaping a draft by forging. It is more interesting to produce a near-net-shape draft to reduce machining. To shape a complex geometry part in one step, the viscosity of the material has to be sufficiently low. This low viscosity requires the generation of a liquid phase in the material but this phase introduces defects in the wrought alloy such as hot cracking, porosity, shrinkage porosity, large shrinkage, macrosegregation solid-liquid. These defects can be reduced by limiting the liquid fraction to 0.1 and thus using thixoforging process. 7075 alloy is particularly sensitive to hot cracking, a low shrinkage is a benefit. Recristallisation process is choosen to obtain a semi-solid globular material. This process uses recrystallisation to transform extruded material into a material that shows a shear thinning-thixotropic behaviour. Heating and extrusion tests help to study the influence of various process parameters on the forming load and the quality of thixoforged parts. We will adjust the parameters of heating and forming on a tool specially designed to thixoforge parts from simple to complex geometry. A study of the influence of parameters on the mechanical properties and the quality of the parts showed very good potential for the thixoforging of 7075 alloy. [less ▲]
