The central pattern generator(CPG) is used to control robot very well. But the adjustment of CPG parameters and it's interaction with the external inputs are still open problems. Based on biological knowledge, the central nervous system rules the switch of the CPG modes. In this paper we focus on the coupling relationship between the cerebral cortex and the CPG and establish the mathematical model...
Web service composition (WSC) is the task of combining a chain of connected single services together to create a more complex and value-added composite service. Quality of service (QoS) has been mostly applied to represent nonfunctional properties of web services and differentiate those with the same functionality. Many research has been done on QoS-aware service composition, as it significantly affects...
Predicting the structure of protein-peptide complexes using computational approaches is a difficult problem whose major challenges are properly dealing with molecular flexibility and conformational changes both of the receptor and ligand. Although significant improvements have been achieved in the modeling of side chains, methods for the backbone flexibility in docking still need improvement. In this...
Logistics distribution of business model is divided into four categories in the paper. Analyzing the intrinsic properties of all kinds of logistics distribution modes, the paper uses the grey situation decision method to compare with and analyze four main logistics distribution modes. It can help enterprises to choose the right distribution model, reduce costs and improve customer service levels....
Risk management in a Virtual Enterprise (VE) is an important issue due to its agility and diversity of its members and its distributed characteristics. In this paper, we develop a partners' risk level considered Constructional Distributed Decision Making (CDDM) model for risk management of the VE. The model has two levels, namely, the top model and the base model, which describe the decision processes...
