Light weight manipulator is characteristic of high load to weight ratio and high speed operation capability, so it has good prospect for application in warehousing logistics and agricultural picking. In this paper, a 4-DOF lightweight arm is designed and its control system and kinematics are studied. Firstly, the control system of the manipulator is determined. A distributed control system (DCS) based...
By applying power usage statistics from smart meters, users are able to save energy in their homes or control smart appliances via home automation systems. However, owing to security and privacy concerns, it is recommended that smart meters (SM) should not have direct communication with smart appliances. In this paper, we propose a design for a smart meter gateway (SMGW) associated with a two-phase...
In this paper, we propose a numerical scheme to solve the time-dependent reaction-diffusion equations by using the meshfree method and approximating the solution using multiquadrics (MQ) Radial Basis Function (RBF). The scheme works in very similar fashion as finite difference methods. The results of numerical experiments are presented, and compared with analytical solutions to confirm the good accuracy...
Biogeography-based Optimization(BBO) is a new biogeography inspired optimization algorithm, and it searches for global optimum through two operators: migration and mutation. To alleviate the slow convergence and premature problem of the BBO, a hybrid optimization algorithm based on BBO and differential evolution(DE) has been presented in this paper. In the given hybrid algorithm new habitats in ecosystem...
The coordination of closed-loop supply chain with risk preference in stochastic demand is studied. Both the market demand is price sensitive and the stochastic demand which possibly exists in reality are considered, and the profit function is no longer being taken as a decision-making but the utility function with the risk preferences of manufacturers and retailers is used in calculating. The retailer...
An innovative concept of urban energy carry capacity (UECC) is introduced in this paper, which evaluate the degree of urban energy sustainability based on the relationship between energy system and city. The UECC model is established in hierarchical structure with pressure and bearing force layer. The pressure layer contains energy and environment indicators system, which cause pressure to city due...
Nonmetallic mineral are widely used in the decoloration treatment of printing and dyeing wastewater. At present, the tourmaline is one of the research hotspots in nonmetallic mineralogy domain, particularly its environmental chemistry behavior. The synthetic dyeing wastewater and actual dyeing wastewater were decontaminated by the tourmaline. The influencing factors, such as adsorption time, reaction...
A good negotiation model is important in order to improve the efficiency for supply chain negotiation. A negotiation model of supply chain based on multi-agent is presented. The model framework for supply chain negotiation and the status of the negotiation agents are defined. We also discuss the negotiation strategy and its learning mechanism of negotiation model. According to the characters of supply...
The study on semantic routing efficiency of DHTP2P networks is a key element to promote the development of P2P networks. it is critical for a P2P routing algorithm to be aware of the network physical topology, which leads to improvement of the routing efficiency. By analyzing the Hashing function’s properties, some novel logical connections are presented among the destination node, the Chord...
