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...
By utilizing biomass gasification, the energy content of the biomass can be utilized to produce gas to be used for cogeneration of heat and power as well as other energy carriers such as fuels for vehicles. The concept is suitable for application to existing CHP plants as well as for utilizing spent liqour in small scale pulp and paper mills. The introduction would enable flexible energy utilization,...
It is urgent to upgrade urban water supply systems to improve water supply security in developing countries. This paper conducts models for analyzing the conflicts between local government and a water company based on game theory. Penalties and subsidies are considered as policy variables to promote water companies upgrading equipments. Then the model is enriched by adding policy variable, reputational...
Air supply is one of the most important factors that influence the combustion of the volatile and carbon in a biomass fired boiler. For many biomass power generation plants, there is insufficient measure to assure the proper air supply. In this study, computational fluid dynamics (CFD) modeling of a double-grate biomass fired boiler was carried out. The three-dimensional Reynolds averaged Nervier-stokes...
This paper explores the effect of model change from direct to distribution on the behavior of buyer and supplier and their relationship. First, a theoretical framework is established to investigate the effect of model change based on literature review. Then, a case study is presented to illustrate the developing relationship between a world-class American company and its Chinese suppliers. Finally,...
The practice of vendor-managed inventory (VMI) draws a high attention from both industrial and academic worlds. On the basis of previous studies, we introduce three parameters, namely the fixed and variable transportation cost, and the service cost per unit, to develop models for the following three scenarios by mainly employing the method used in Dong & Xu (Ref.13): (1) traditional supply chain...
The effectiveness of services provided by a business incubator is the basis and premise for promoting the incubator itself and for incubating and developing new ventures inside. Services in different forms, contents and levels may influence the performance of incubated firms such as surviving rate and growth rate. We first classify incubator services into several types including infrastructure, educating,...
