Tradition single-model adaptive signalprocessing system faces many difficulties. when it is applied in complex signals processing and different conditions, such as constant frequency wide-band signal, fast-varying signal and changed disturbing conditions. In this paper, multi-model adaptive signalprocessingsystems based on multi-model adaptive control structure is presented.

A system of networked smart motors is developed to reduce complex cable harnesses. Motor control signals are sent over the DC power bus line and received by motors with integrated power amplifiers and controllers. Unlike traditional AC power line communication, the noise level and signal attenuation are much lower for the DC power bus communication. This allows for high fidelity, broadband communication among many smart motors without bulky, costly cables. A modem is designed to exploit the features of the DC power bus communication. Experimentation is done to verify that the DC bus line is indeed useful for communication. An experimental setup was developed to identify the noise spectrum and signal transmissibility of the consolidated power-signal line. Optimal carrier frequency and filter parameters are then obtained based on the experiments.

For a class of nonlinear continuous time systems x = f(x) + Bu + d, when the nonlinear function f(x) is bounded or satisfies linear growth condition with un-known growth coefficient, we first prove that x falls into a compact set, then two adaptive regulators are proposed based on the approximation capability of direct basis function networks. According to the Lyapunov stability theory, the control algorithms are proved to be globally stable, the state of closed-loop system is uniformly ultimately bounded and the control law is continuous.

This paper presents a new visual gesture recognition method for the human-machine interface of mobile robot teleoperation. The interface uses seven static hand gestures, each of which represents an individual control command for the motion control of the remote robot. All the important aspects to develop such a interface are explored, including image acquisition, adaptive object segmentation with color image in RGB, HLS representation, morphological filtering, hand finding and labeling, and recognition with edge codes, template matching, and skeletonizing. By choosing processing methods and procedures properly, a higher ratio of correct recognition and a faster speed are achieved from the experiments.

intelligentsignalprocessing provides a wealth of technologies, such as fuzzy logic, neural network, evolutionary computation that can be applied to the design and operation of communications systems. In this article, we present applications of fuzzy logic to problems in mobility management of heterogeneous wireless communication network, which including location management and handover management. In both cases, multiple criteria should be considered to implement multiple criteria decision-making (MCDM) because of the heterogeneity of the different system entities (the user, the terminal, the services and the network). Fuzzy based MCDM method is presented for access network selection and the vertical handover decision.

This paper presents a new teaching method that effectively integrates IT technology into teaching and teaming process. The method is well suited for teaching engineering subject in large class and contains three major components: conceptual visualizing, just-in-time teaching, and knowledge transferring. The success of the method is based on an all-in-on Educator-to-Learning portal that provides course material management, dynamic tutorial publication, intelligent tutorial diagnosis, multimedia demonstrations for visualization of difficult concepts, online simulation, virtual laboratory, and etc. The new method brings a new learning experience to students in a learner centered environment.
