ChinaGrid Annual Conference (ChinaGrid)

作者： Gang Zhao Weimin Zheng Jinjing Zhao Hua Chen Department of Computer Science and Technology Tsinghua University Beijing China Beijing Institute of System Engineering Beijing China

The security of the web-service program is a very significant facet in the grid computing environment. A fuzzer is a program that attempts to discover security vulnerabilities by sending random input to an application. How to efficiently reduce the fuzzing data scale with the assurance of high fuzzing veracity and vulnerability coverage is a very important issue for its effective practice. In this paper, aimed at the web-service program, a new heuristic method for fuzzing data generation named as H-Fuzzing is be presented, which has high program executing path coverage with the information from the static analysis and dynamic property of the program. The main thought of H-Fuzzing is collecting the information of the key branch predications and building its relations with the input variables in order to supervise the dimension reducing of the fuzzing data aggregation.

The purpose of this paper is to identify the threats that exist in Healthcare Information systems (HIS). The study has been carried out in three different departments namely, Information Technology department (ITD), Medical Record department (MRD) and X-Ray department in one of the leading government supported hospital in Malaysia. The hospital was equipped with Total Hospital Information system (THIS) environment. The data were collected using in-depth structured interviews. The study identified 22 types of threats according to major threat categories based on ISO/IEC 27002 (ISO 27799:2008). The result shows the most critical threat for the THIS is the power failure. In addition, acts of human error or failure threat also show high frequency of occurrence. The contribution of the paper will be categorization of threats in HIS and can be used to design and implement effective security systems and policies in healthcare setting.

RFID system is gaining popularity and attracting interest from both the enterprises and academic institutes. But now, we face several security problems and challenges in RFID systems. In human centric applications, location privacy problem is the most important issue that should be solved. In this paper, we propose a RFID authentication scheme that achieves the goal of location privacy. We also cite the threat model to analysis security threat of our protocol. Moreover, our scheme can be implemented with low-cost and high efficiency.

In this paper, we propose 24-ary grid graphs corresponding to rectangular solid dissections for ruled line preserving operations. We also show a data structure called H9CODE that corresponds to the 24-ary grid graphs. Furthermore, we describe a voxel unification method in the 24-ary grid graphs and show that the 24-ary grid graphs are an effective modei to represent solid graphics.

Accurate forecasting of the rice yields is very important for the organization to make a better planning and decision making. In this study, a hybrid methodology that combines the individual forecasts based on artificial neural network (CANN) approach for modeling rice yields was investigated. The CANN has several advantages compared with conventional Artificial Neural Network (ANN) model, the statistical the autoregressive integrated moving average (ARIMA) and exponential smoothing (EXPS) model in order to get more effective evaluation. To assess the effectiveness of these models, we used 38 years of time series records for rice yield data in Malaysia from 1971 to 2008. Results show that the CANN model appears to perform reasonably well and hence can be applied to real-life prediction and modeling problems. © 2009 Asian Network for Scientific Information.

Traditional model checking methods to find safety and liveness violations are usually applied in the abstract model, while existing runtime monitoring methods to check the predicates can not obtain the high path coverage. This paper presents a hybrid model checking and runtime monitoring method to check the safety and liveness properties in real complex distributed C/C++ Web service systems,which can offer both a richer and more efficient way to search violations specified by linear temporal logic. Based on our model checking engine to walk different paths, we adopt the finite linear temporal logic engine to dynamically verify properties in C/C++ Web service systems. Then, we use the practical examples to illustrate its usage and applications in real C/C++ Web service systems.

This paper describes Data Modeling for unstructured data of Diffusion Tensor Imaging (DTI). Data Modeling is an essential first step for data preparation in any data management and data mining procedure. Conventional Entity- Relational (E-R) data modeling is lossy, irreproducible, and time-consuming especially when dealing with unstructured image data associated with complex systems like the human brain. We propose a methodological framework for more objective E-R data modeling with unlimited query support by eliminating the structured content-dependent metadata associated with the unstructured data. The proposed method is applied to DTI data and a minimum system is implemented accordingly. Eventually supported with navigation, data fusion, and feature extraction modules, the proposed system provides a content-based support environment (C-BASE). Such an environment facilitates an unlimited query support with a reproducible and efficient database schema. Switching between different modalities of data, while confining the feature extractors within the object(s) of interest, we supply anatomically specific query results. The price of such a scheme is relatively large storage and in some cases high computational cost. The data modeling and its mathematical framework, behind the scene of query executions and the user interface of the system are presented in this paper. © 2009 SPIE.

This research aims to develop a combined sense system that uses both the sense of a force feedback as well as visual feedback in the shape of microscopic features from a micro sample. It is thought that the efficiency of minute work would be improved if the operator could obtain a sense of force while using a manipulator. We used a cantilever to touch a minute object and obtained anti-power from the degree of its bend. We made a haptic device, which gives a sense of force to the operator, who can feel the force when he touches a sample with a cantilever. In addition, when he uses the haptic device in a simulated manner, he can feel as if he had touched a sample. ©ISAROB 2009.

Nonlinear internal wave run-up on impermeable steep slopes

Journal of Offshore Mechanics and Arctic engineering 2009年第4期131卷 1-5页

作者： Tseng, I-Fan Chen, Chen-Yuan Kuo, Hui-Ming Department of Marine Environment and Engineering National Sun Yat-Sen University Kaohsiung 80424 Taiwan Department of Computer Science National Pingtung University of Education No. 4-18 Ming Shen Rd.

Laboratory experiments were conducted to investigate the run-up of internal solitary waves (ISWs) on steep uniform slopes in a two-layered fluid system with a free surface. A 12 m long wave flume, which incorporated a movable vertical gate for generating ISWs, was used in the experiments. A steep uniform slope was modeled at one end of the flume. In the present study we looked at internal waves with small and large amplitudes using a steep uniform slope (from one of Θ=30, 50, 60, 90, 120, and 130 deg) much longer than those previously published in the literature. Results collected from a wide range of experimental runs show that the run-up height depends on the planar slope, while the breaking depth is only antecedent to the amplitude of an ISW. The overall quantitative agreement with the linear feature aspects of the incident wave amplitude is encouraging. Copyright © 2009 by ASME.
