Gold nanoparticles (AuNPs) embedded in chitosan (CHI) film, well-dispersed and smaller in size (about 10 nm), were fabricated by one-step electrodeposion on Au microelectrode in solution containing chitosan and chloride trihydrate. The nano-structure CHI-AuNPs composite film offers abundant amine groups, good conductivity, excellent biocompatibility and(More)
multi-view autostereoscopic three-dimensional (3D) display has been one of the most popular research issues in the world. And 3D displays are classified into two types: stereoscopic 3D display and autostereoscopic 3D display. The former includes head mount system, anaglyph system, polarized filter system, field sequential system and so on. The latter is(More)
This paper first presents a geometric analysis of the convergence condition for the Foschini-Miljanic power control algorithm. Then, based on the analysis, the Dynamic Distributed Power Control MAC (DPC-MAC) scheme is proposed for wireless networks. DPC-MAC achieves high spatial reuse, since power control enables nesting of concurrent links, thereby(More)
The multi-depot vehicle routing problem with inter-depot routes (MDVRPI) is an extension to the classical Vehicle Routing Problem (VRP); it is the major research topics in the supply chain management field. It is an extension of the multi-depot vehicle routing problem in which vehicles may be replenished at intermediate depots along their route. In this(More)
In this study, we consider the application of a hybrid particle swarm algorithm to the grain logistics vehicle routing problem with time windows (VRPTW). VRPTW is a variant of the well-known well-studied vehicle routing problem (VRP), which the objective is to use the limited vehicles so that the maximum number of jobs can be completed with minimum cost.(More)
Data fusion was used to predict the safe value of grain environment in different operational conditions. The temperature, humidity, moisture, pest and etc, were used as inputs to the data fusion center and network. Feed-forward artificial neural networks with 4-10-5 arrangements were capable to estimate the safe value of grain environment as the outputs.(More)
Power control plays an important role in the design and operation of wireless networks. In this paper, we first define two critical metrics, transport density and channel access time to measure the system performance. The trade-off between these two metrics as a function of the peak power constraint is discussed in two cases, a fixed peak power case and an(More)
The multi-depot vehicle routing problem with time windows (MDVRPTW) is an extension to the classical Vehicle Routing Problem (VRP); it is the major research topics in the supply chain management field. It aims to designing a set of minimum-cost routes for a vehicle fleet servicing many customers with known demands and predefined time windows.In this paper a(More)
