In this paper, we develop a new technique for partitioning of source and channel coding bits for packet-based scalable streams and a general unequal error protection channel coding scheme. Unlike the previous algorithms, we regard coded source streams as a collection of different subsets with different importance and adaptively select some of them to transmit with optimal channel coding subject to...
In this paper we study the problem of relay-enhanced cell (REC) coverage for which relay location is optimized to maximize the achievable REC radius. The problem is investigated for both Rayleigh and Rician relay fading channels, under a pre-determined user's outage probability constraint. We propose a statistical approach to formulate the problem and develop an optimization algorithm for it. The...
With the technical requirements for automated stereoscopic warehouse increasingly, the application of bend aisle stereoscopic warehouse is more and more extensive. Through taking the stereoscopic automated warehouse in Qinhuangdao as a research object, This paper describes the order picking path optimization and scheduling algorithm for bend aisle, solves the problem of a stacker's order picking in...
This paper presents a new electromagnetic simulator called HOBBIES (Higher Order Basis Based Integral Equation Solver). HOBBIES is based on a parallel In-Core and Out-of-Core integral-equation solver and a personal pre- and post-processor called GiD®. HOBBIES presents some important features such as multiplatform and multilanguage environment, definition of models using symbolic variables, automatic...
The NEWUOA is a newly developed trust region based derivative-free method for solving unconstrained optimization problems. We present in this paper this powerful tool for antenna optimization. Two antenna design examples are optimized using simplex method, conjugate gradient method and the NEWUOA algorithm. Optimization results are presented and compared. The NEWUOA shows good performance and is proved...
Scheduling and decision-making in container terminal logistics system (CTLS) has been the focus of research and application. This paper remodels the operation of CTLS through advancing an innovative multilevel control and feedback framework and methodology. That utilizes the knowledge engine which lies in business intelligence platform to drive the simulation and optimization engine indwelling in...
