The recent explosive growth of multimedia information in many applications requires advanced techniques for multimedia information retrieval (MIR). Audio is one of Important media in multimedia and contains abundant information. Recent development in MIR has revealed that audio information can provide effective contents to retrieve multimedia information. Consequently, it has been paid more and more attention to how to classify audio information. Many existing and new research issues can lead to improve the retrieval efficiency, effectiveness, and accessibility. This paper provides a hybrid classification method for audio indexing and retrieval. It firstly describes main audio characteristics and features and the basic theory of Support Vector Machine (SVM) and Independent Component Analysis (ICA). Finally, the hybrid method that integrates ICA and SVM is presented and applied into audio classification. © 2006 IEEE.

Adopting the traditional object-oriented and component-based methods, the software architecture design pattern can be applied in the concurrent, realtime and distributed fields, which will replace the kind of strong-coupling and process-oriented development predominant in the real-time embedded software to satisfy the needs of the fast development of hardware and communication technology. Combined with the mechanistic design pattern put forward by Gamma et al. (like layer, microkernel, component, etc.), in the light of the view between the subsystem and the component architecture and of the concurrency, correct design pattern is generated by means of pattern incubating, mining or instantiation, which is then applied to develop a robust and scalable architecture for real-time system. As the Component-based Software engineering (CBSE) can effectively enhance the quality and efficiency of the software development process, the technology is introduced to architecture design, offering mature applications by means of framework instantiation. Based on the hybrid design pattern, the architecture and the process of the software become mutually reinforcing and complementary, and both the interior quality and the process quality of the software are guaranteed.

In mobile ad-hoc networks (MANET), the nodes intercommunicate through single-hop and multi-hop paths in a peer-to-peer fashion. Intermediate nodes between two pairs of communication nodes act as routers. Thus the nodes operate both as hosts and routers. The nodes are mobile, so the topology of the network may change rapidly and unexpectedly. One of well-known routing protocol for ad-hoc networks is zone routing protocol (ZRP). However when the protocol searches for a new route, it sends many useless control packets, which increase the network load and decrease the network performance. In this paper, we propose an enhanced zone routing protocol (EZRP). In EZRP, each node calculates the reliability of the route. In the case of reliable route, the source node sends the data packet directly to the destination node using that route without route searching. While, in the case of unreliable route, the source node searches for a new route again. We show that the network performance can be improved by using EZRP.

The application of fluorescent spectrometry in quality detection and brand identification of fermentation food was studied. Three brands of stronger alcohol with a fragrant flavor (Gujing ju, Luzhoujiao ju, Shuanggou daqu) which come from different regions were compared in study of spectroscopy. We had detected each fluorescence spectra of different brands which were prompted by the UV-light with different wavelength and excited by the UV-light with same wavelength. The experimental results indicate that each alcohol has its owner fluorescence spectra, even excited by the UV-light with same wavelengh, each alcohol has different fluorescence spectra.

Detection and prevention of Phenylketonuria (PKU) is becoming more and more important. However, the current methods are either imprecise or time-consuming. We propose a biosensor system based on phenylalanine ammonia-lyase (PAL) immobilized on an ammonia electrode to measure blood phenylalanine for PKU prevention. The biosensor exhibits good linearity from 10-5000μM and the response time is only about 2 minutes. It remains stable for at least 5 days and less than 20% drop of the original activity after ten day storage at 4, while the service life of the biosensor could be up to 30 days. We also develop an intelligent system to ensure optimal conditions for operation and preservation of the biosensor and to make detection more convenient and reliable. All of these advantages indicate that the newly developed method could be a better one for solving the problems of PKU detection. © 2005 IEEE.

To achieve detection, monitoring, and automation of stareh graft eopolymerzation at any time, the investigation is being made according to luminescenee of free radicals produced in the reaction. The investigations on the fluorescence spectra of starch-water suspension excited by ultraviolet (UV) light and its characteristics contribute to study the characteristics and mechanisms of free radicals coming into being, emitting, and disappearing. Fluorescence spectra of starch, dextrose, sucrose, and maltose excited by 260-nm light are compared and their similarities further verify that this fluorescence comes from the transition from nonbonding. namely n electrons in the hetero-atom (O) of the functional group (C-O-C) called ether linkage, to the antibouding orbital σ*. The functional group is a part, of six-membered ring structure in starch molecule. Meanwhile, the experimental results indicate that relative peak intensity of fluorescence emitted by 1% starch suspension comes to climax when starch suspensions with different concentrations are excited by the same wavelength.

Wavelet transform is an ideal way for edge detection because of its multi-scale property, localization both in time and frequency domain, sensitivity to the abrupt change of signals, and so on. An improved algorithm for image edge detection based on Lifting Scheme is proposed in this paper. The simulation results show that our improved method can better reflect edge information of images.

In order to restrain odd-order harmonic distortion and common model disturbing signal effectively, a MOCC II-based filter circuit with high-order fully differential leapfrog-type current mode is presented and corresponding design scheme is proposed. The PSPICE simulation to 4th Butterworth filter with 1 MHz but frequency is made. Simulation results show that the circuit can restrain odd-order harmonic distortion and common model disturbing signal more effectively, with low sensitifity of passive LC ladder-type network.
