A software platform for demonstration and performance evaluation of network aware joint optimization of wireless video transmission is presented in this paper. This demonstrator has been realized in the framework of the IST PHOENIX project (www.ist-phoenix.org) and is based on the joint system optimization model developed by the project. After a description of the considered cross-layer approac...

Query optimizers often have diiculties with the treatment of user-deened functions. In particular, the optimization of joins involving complex, user-deened predicates rather than just simple arithmetic comparisons may lead to query plans of poor quality. In this paper, we identify a class of user-deened functions that can be included in queries in such a way that eecient query optimization is s...

For the microelectronics manufacturing industries that have uncertain demand, high volume cost and Oligarchs characteristics, we often discuss the possibility of competitors on the capacity of strategy. First of all we use the industry data to analysis the manufacturing cost, demand and the historical situation of the revenue and we also discuss the influence about the uncertain demand and high...

The purpose of this article is to present an optimization model for designing an acceptance sampling plan based on cumulative sum of run length of conforming items. The objective is to minimize the total loss including both the producer and consumer losses. The concept of minimum angle method is applied to consider producer and consumer risks in the optimization model. Also the average number o...

optimization of cutting conditions is a non-linear optimization with constraint and it is very important to the increase of productivity and the reduction of costs. in recent years, several evolutionary and meta-heuristic optimization algorithms were introduced. the cuckoo optimization algorithm (coa) is one of several recent and powerful meta-heuristics which is inspired by the cuckoos and the...
