In this paper, we consider the performance behavior of two protocols: AODV and DSR using TwoRayGround model. We study the routing efficiency of the ad-hoc sensor network and compare the performance of two protocols for different scenarios using the routing efficiency concept. By computer simulations, we found that the routing efficiency of DSP protocol is better than AODV protocol.

IEEE Symposium on Bioinformatics and Bioengineering (BIBE)

The breadth of biological data collected in the last decade has far outstripped the methods available to process it. To effectively investigate and explore this abundance of data, novel automated collection and analysis approaches must be devised. We have developed a new open software framework, the Open Genomic Analysis Platform (OGAP), to aid in the analysis of genomic data. It is capable of analyzing a variety of data source, and focuses on using information theory to characterize data. The frameworks has is capable of import a variety of genome tied data, and provides custom analysis and visualization of results. We then demonstrate the use of this framework analyzing the Prochlorococcus Marinus organism. We show a strong correlation between the information content of sequence data and up regulation of gene expression during lytic infection.

A new robust watermarking 3D mesh model algorithm is presented in this paper. We embed two different watermarks into a 3D mesh. One of the two watermarks is based on feature information and another is embedded by Nielson norm. The two watermarks do not disturb each other. Since the algorithm is blind, it does not need the original model during extraction. The algorithm is applied to many mesh models. These experiments show that the watermarking scheme not only can keep original mesh feature information but also can resist some attacks, such as affine transformation, noising and cropping.

In this paper, we present the design and implementation of the JXTA-based e-Learning P2P system. We also show the design and implementation of a smart box environment that will be used for stimulating the learners to increase the learning efficiency. The smart box is intended to be integrated with our P2P system as a useful tool for monitoring and controlling learners' activity. Finally, it is also useful to evaluate the feasibility of our P2P platform to integrate different computational devices.

Due to the opportunities provided by the Internet, people are taking advantage of e-learning courses and during the last few years enormous research efforts have been dedicated to the development of e-learning systems. So far, many e-learning systems are proposed and used practically. However, in these systems the e-learning completion rate is low. One of the reasons is the low study desire and motivation. In our previous work, we implemented a e-learning system that is able to increase the learning efficiency by stimulating learners motivation. In this work, we designed and implemented new functions to improve the system performance.

Cluster formation and cluster head selection are important problems in sensor network applications and can drastically affect the network’s communication energy dissipation. However, the selection of cluster head is not easy in different environments which may have different characteristics. In this paper, in order to deal with this problem we propose a power reduction algorithm for sensor networks based on fuzzy logic and number of neighbor nodes. We evaluate the proposed system by simulations and show that proposed system makes a good selection of the cluster head.

A virtual type for a multiple-type object and its implementation

引用

Systems and computers in Japan 2007年第11期38卷 25-35页

作者： Sato, Hideki Aritsugi, Masayoshi School of Informatics Daido Institute of Technology Nagoya 457-8530 Japan Department of Computer Science Faculty of Engineering Gunma University Kiryu 376-8515 Japan

To deal with the evolution of data and applications and with the existence of multiple views for the same data, the object data model needs to be extended with the object extension functionality to allow an object to dynamically change its type, and the object viewing functionality to allow an object to be seen as if it had a different structure and behavior. This paper proposes the virtual type facility which provides a persistent object of INADA, an enhanced C++ persistent programming language compliant with the ODMG standard, with a different structure and behavior from those of its base types. Additionally, it presents the implementation details of the facility. The virtual type facility gives a different interface of an object to redefine its structure and behavior without affecting the behavior of a base type, while the multiple-type object of INADA allows an object to be dynamically extended to model an entity which changes its behavior with time. The virtual type facility integrates the object extension functionality and the object viewing functionality for dealing with the database evolution. © 2007 Wiley Periodicals, Inc.

Mixture regression for covariate shift 19

In supervised learning there is a typical presumption that the training and test points are taken from the same distribution. In practice this assumption is commonly violated. The situations where the training and test data are from different distributions is called covariate shift. Recent work has examined techniques for dealing with covariate shift in terms of minimisation of generalisation error. As yet the literature lacks a Bayesian generative perspective on this problem. This paper tackles this issue for regression models. Recent work on covariate shift can be understood in terms of mixture regression. Using this view, we obtain a general approach to regression under covariate shift, which reproduces previous work as a special case. The main advantages of this new formulation over previous models for covariate shift are that we no longer need to presume the test and training densities are known, the regression and density estimation are combined into a single procedure, and previous methods are reproduced as special cases of this procedure, shedding light on the implicit assumptions the methods are making.

System requirements expressed as scenarios represent a rich source of knowledge about a system and the context in which it is used. This is because the scenarios are the result of extensive collaborative efforts of a wide variety of stakeholders and are in a form to which all can relate. Ideally, they serve to represent the interests of all stakeholders at each stage of the development life cycle. Our focus in this paper is system testing against requirements. In particular, we show (1) how the knowledge represented in scenarios (using ScenarioML) can be directly transformed into an operational knowledge base in a rule-based programming language (JESS), (2) how this knowledge base can be used in system testing to compute, manage, and compare expectations of system behavior to actual system behavior relative to the requirements, and (3) how this can be achieved in a manner that is transparent to all stakeholders. The power of this approach derives from the peculiarly reflective character of knowledge based systems and their explicit use of meta-information and meta-information processing. We demonstrate the viability of our approach by its application to the AquaLush system in which we detected several violations of the system's stated requirements.
