This paper focuses on a single crane scheduling problem in order to pick all demanded coils for downstream stage production or for customer which is motivated by cooled-rolling material warehouse in the iron and steel enterprise. If a demanded coil is in the upper level, it can be picked up directly to designated place (transportation operation). If a(More)
In this paper, JPEG bitstreams has been analysized through its rapid analytical algorithm. Its optimized algorithm which was based on optimized huffman table has been studied. The experimental research shows that optimized bitstreams can save 2.4%-27.8% size of file. In order to obtain the specific decoding information of each MCU block, the fast(More)
For designing wireless sensor networks, the coverage of the sensing area, sink location and data routing are three major issues. This paper considers three technique problems within a unified framework and develops a mixed-integer linear programming formulation. Further, a hybrid meta-heuristics is proposed to solve the solution. The outer loop of this(More)
