Summary form only given. This paper describes a topology optimization method for a structure to get the best acoustic characteristics, e.g., sound power. The method is applied via shifting the eigenfrequency away from the excitation frequency. Topology optimization design of vibrating composite material elastic plate with respect to minimization of the sound radiation has been studied. Volumetric...
3G mobile communication networks such as UMTS provide wide area Web access. However, Web latency is usually beyond users' tolerable waiting time even in wired networks. In UMTS networks, mainly due to large RTTs and limitations of existing HTTP, Web latency increases dramatically. In this paper, we introduce a Web acceleration scheme, proxy-based object packaging and compression (POPC), for reducing...
An improved ant colony optimization (IACO) algorithm is proposed to the flexible job shop scheduling problem (FJSSP) in this paper. IACO algorithm provides an effective integration between ant colony optimization (ACO) model and knowledge model. In the IACO algorithm, knowledge model learns some available knowledge from the optimization of ACO, and then employs the existing knowledge to guide the...
Computing high-technology manufacturing (HTM) productivity level and growth rate have gained a renewed interest in both growth economists and trade economists. Measuring productivity performance has become an area of concern for companies and policy makers. A novel way about nonlinear regression modeling of high-technology manufacturing (HTM) productivity with the potential support vector machines...
The efficiency of transferring a pack of small-sized flies or a large-sized file is very low in FTP based file transfer system. To solve this problem, we have studied the optimized method of different types of file transfer and present an adaptive transfer algorithm. Based on this algorithm. We design and implement the file transfer subsystem of global distributed storage system.
