The explosive and unprecedented growth with new innovation in wireless technology has opened up a new window for life-saving telemedicine services. After every couple of weeks a competitive solution is provided with the help of state-of-the-art technology to serve human beings every where on their move. By adopting advantages of telemedication the life in remote areas is facilitated. In this paper the working design of a quality ensuing wireless telemedicine system is proposed. The system activates real-time interactive medical data in a wireless environment. It handles vital sign telemonitoring technique that acquires, stores, and forward readings of electrocardiographs (ECG) and temperature over the wireless LAN. The browser based application is customized for 802.11b. The paper describes the quality ensuing design and implementation of portable medical unit that allows monitoring any where and that can be uses for various monitoring scenarios of homecare-units, hospital, the emergency and disaster relief centers. Existing telemedicine systems use traditional hard-wired, bandwidth-reserved mechanisms or road-mobile medical services for a real-time monitoring of patient. The preliminary results of telemedication determine that this level of service is not beneficial in monitoring patient with the help of stationary system or mobile-medication. Moreover, switching via GSM may guarantee a territory in range but low bandwidth, small data rates and system expense become an obstacle. The wireless broadband services guarantees full coverage and system expenses are for session based only. This research paper demonstrates for a practicable telemedication system with potential security features available with IEEE 802.11b standard.

An LSB data hiding technique using prime numbers

In this paper, a novel data hiding technique is proposed, as an improvement over the Fibonacci LSB data-hiding technique proposed by Battisti et al. [1]. First we mathematically model and generalize our approach. Then we propose our novel technique, based on decomposition of a number (pixel-value) in sum of prime numbers. The particular representation generates a different set of (virtual) bit-planes altogether, suitable for embedding purposes. They not only allow one to embed secret message in higher bit-planes but also do it without much distortion, with a much better stego-image quality, and in a reliable and secured manner, guaranteeing efficient retrieval of secret message. A comparative performance study between the classical Least Significant Bit (LSB) method, the Fibonacci LSB data-hiding technique and our proposed schemes has been done. Analysis indicates that image quality of the stego-image hidden by the technique using Fibonacci decomposition improves against that using simple LSB substitution method, while the same using the prime decomposition method improves drastically against that using Fibonacci decomposition technique. Experimental results show that, the stego-image is visually indistinguishable from the original cover-image. © 2007 IEEE.

This paper describes annotations for the Corpus of Spontaneous Japanese. The information we annotated to the corpus includes morphemes, clause units, dependency structures, summaries, and discourse structures. They are integrated in the form of XML. Morphological information was semi-automatically annotated to the transcribed text by reducing the human labor cost within the framework of morphological annotation that we proposed. Next, clause unites were detected based on the morphological information as basic units for our annotation. Then, dependency structures, summaries, discourse structures were annotated based on the clause units.

Structure alignment could help to find shape similarities between proteins and guide structure classification and fold recognition. Common substructure detection and extraction are especially important, for which could guide the biologist to discover binding site or active site. We represent each segment of alpha-carbon backbone by using dihedral angles and curve moment invariants. Then, local and global structure alignment could be performed by iterative closest point algorithm. Maximum common substructures between a pair of proteins or within a protein could be found. Active sites also could be detected by the proposed algorithm.

3-D projective moment invariants

Journal of Information and Computational Science 2007年第2期4卷 821-828页

2-D projective moment invariants were firstly proposed by Suk and Flusser in [12]. We point out here that there is a useless projective moment invariant which is equivalent to zero in their paper. 3-D projective moment invariants are generated theoretically by investigating the property of signed volume of a tetrahedron. The main part is the selection of permutation invariant cores for multiple integrals to generate independent and nonzero 3-D projective moment invariants. We give the conclusion that projective moment invariants don't exist strictly speaking because of their convergence problem.

IEEE International Conference on Engineering Management (EMC)

作者： Martin Pazderka Thomas Grechenig Institute of Computer Aided Automation Research Group for Industrial Software University of Technology Vienna Austria

Within the project management community, the concept of project management maturity models has recently been receiving a lot of business and research attention. Although the structure of most models has now been well defined and is quite sophisticated, a lot of potential exists in extending the currently described best practices that are part of these models by additions for specific problem areas, such as working with virtual (geographically distributed) teams. This paper describes the challenges faced by those working with virtual teams in the context of project management maturity models, establishes a strategy how these models can be extended to address these challenges, and identifies a set of best practices for virtual team collaboration that can be integrated into current maturity models.

The Technical University of Berlin has the objective to develop such components, which are not available yet. The first device under development is the so called "micro wheel", which is designed to be used in pico satellites, allowing a precise 3-axis attitude stabilization. The verification of these wheels in space will be done by BEESAT, the first pico satellite of TU Berlin. The main objective of BeeSat is the on orbit verification of newly developed micro wheels for pico satellite applications. These wheels, with the size of a one Euro coin in diameter, supported by DLR (FKZ 50JR0552) and developed in cooperation with Astro-und Feinwerktechnik, will drastically improve the actuation capabilities of pico satellites.

IEEE International Conference on Networking, Sensing and Control

作者： Yuying Wang Guanghua Lu Jinyuan Jia Hongji Yang Software Research Institute and the Department of Computer Science and Technology Zhuhai College Jilin University China Department of Software Engineering De Montfort University UK Software Research Institute Zhuhai College Jilin University China

We propose a three-layer framework and a Globus-based architecture of grid-enabled multi-node downloading mechanism to facilitate a flexible and scalable downloading large scale distributed virtual environments. In our proposed architecture, each grid node is regarded as a potential downloading service provider when available. The performance of downloading DVE is proportional to the number of grid nodes participated in the downloading task. A specific component, multi-node downloading (MND) is devised for supporting remote multi-thread downloading DVE based on Globus platform. MND consists in a multi-node downloading protocol and an adaptive multi-node downloading balancing (AMDB) algorithm. MND is deploying onto our developing "Virtual Zhuhai Campus of Jilin University". Initial experimental results show the feasibility and effectiveness of our approach.
