Theoretical and experimental studies associated with electric field effects on the stability and transport are briefly surveyed. The effects of radial electric
Traditional PCA is a linear method, but most engineering problems are nonlinear. Using the linear PCA in nonlinear problems may bring distorted and misleading r
Session Initiation Protocol(SIP)is a key technology in the Internet telephony or Voice-over-IP(VoIP), also it is an important signaling technology in the next g
Engineering design and geometric modeling often require the ability to modify the shape of parametric curves and surfaces so that their shape satisfy some given
A pattern is used to describe best practices and principles. Patterns have been used successfully in architecture and in software design. We propose to apply th
A kind of fault diagnosis system of molten carbonate fuel cell (MCFC) stack is proposed in this paper. It is composed of a fuzzy neural network (FNN) and a faul
This paper addresses the problem of real-time position and orientation estimation of networked mobile robots in two-dimensional Euclidean space with simultaneou
