A nonminimum-phase channel can always be decomposed into a minimum-phase part and an all-pass part. In our approach, called all-pass CMA, the dimensionality of the CMA algorithm has been reduced to improve blind equalization of a nonminimum-phase channel's all-pass part. The dimensionality reduction has been performed by parameterizing the CMA cost function in terms of the nonminimum-phase zero location of the all-pass part to be compensated. Currently, all-pass CMA can only compensate a single nonminimum-phase zero. However, compared to CMA, it typically provides a faster and more accurate compensation of this zero.

Correct annotation and identification of salient regions in Kidney biopsy images can provide an estimation of pathogenesis in obstructive nephropathy. This paper presents a tool for the automatic or manual segmentation of such regions along with methodology for their characterization in terms of the exhibited pathology. The proposed implementation is based on custom code written in Java and the utilization of open source tools (i.e. RapidMiner, ImageJ). The corresponding implementation details along with the initial evaluation of the proposed integrated system are also presented in the paper.

This paper considers the characteristics of high-speed train in precise timing information, such as arrival time, dep.nding duration on station, traveling time and location of the train, to design a video proxy agent for VoD service in train. Based on the information of current active video streams, a burst pre-fetching scheme in video proxy agent is developed when the high-speed train dep.nds on station. The video data required by the passengers in near future are burst downloaded to the video proxy to release the bandwidth constrain during the train traveling. The most of playback video data can be provided by the video proxy agent during the train traveling. The burst pre-fetching scheme increases the system performance and video playback quality. The simulation result reveals that the proposed scheme has better results in term of system capacity and the amount of missed deadline data compared with other schemes.

With the wide acceptance and development of the Internet, it is trend to integrate all of services and devices into Internet. At the same time, the fast development of communication technology that is evolved from narrowband dial-up networks to current broadband networks, from fixed PSTN phone to mobile phone and from wired network to wireless network. In the foreseeable future, the communication will be converged to IP centric networks to come up pervasive/ubiquitous network environments. In this paper, the functions of SIP protocol, video/audio codec, and video/audio streaming are integrated to realize a video/audio phone system in embedded platform. Based on the multi-thread environment, the modules of motion JPEG, SIP signaling protocol, and video/audio streaming are designed to come out a SIP-based video/audio streaming system. The system can be applied to the applications of remote surveillance, digital door phone, interphone, and Internet phone.
