In this paper, a technique for visualizing the changing rank and value of events simultaneously with time, as well as a trend analysis tool that uses the resulting visualization, are proposed. This technique facilitates analysts' understanding of the trends of both the entire data set and each event. It also uses colors, which are estimated automatically from the events' text labels, to represent the category to which events belong. Using the tool, the authors analyzed trends of topic data extracted from Twitter as use case, and could observe the trends and overview of Twitter. In addition, using the tool it is possible to present the different ways in which people who use different media think, using media-generated data. © 2013 IEEE.

Towards Semantic Mutation Testing of Aspect-Oriented Programs

引用

Journal of Software engineering and Applications 2013年第10期6卷 5-13页

Aspect-oriented programs have received much attention from software testing researchers. Various testing techniques and approaches have been proposed to tackle issues and challenges when testing aspect-oriented programs including traditional mutation testing. In traditional mutation testing of aspect-oriented programs, mutants are generated by making small changes to the syntax of the aspect-oriented language. Recently, a new approach known as semantic mutation testing has been proposed. This approach mutates the semantics of the language in which the program is written. The mutants generated misunderstandings of the language which are different classes of faults. Aspect-oriented programming presents itself with different properties that can be further explored with respect to semantic mutation testing. This paper describes various possible scenarios that semantic mutation testing strategy might have particular value in testing aspect-oriented programs.

Modern software frameworks for Model-Based systems engineering (MBSE) methodologies are proprietary and commonly restricts to a poor choice of domain specific languages. Furthermore, the interoperablity and model interchange support between frameworks is a technically hard challenge. The industrial strength standard OMG MOF (Meta-Object Facility) is a solid approach for the definition of domain specific languages. Applying meta-modeling techniques to existing modeling and simulation frameworks reduces obscurity of proprietarity and implicitely language characteristics. On the other hand, standard compliance improves product openness/transparency, reliability and confidence as for primary modes of operation. This paper presents a methodology to incorporate methods of meta-modeling and standard compliant domain specific languages in an existing modeling and simulation framework. First results are emerged and exemplified for an effective modeling dialect called MML (MLDesigner Modeling Language). Future prospects reviews already accomplished goals in this project, address several alternatives and improvements and gives an overview of ongoing development.

Wireless sensor network technologies can be used for industrial embedded system design to save cabling cost and weight. However, their environment, architecture, and design issues are quite different from original sensor network applications. Simulation tools and system design environments have to be adapted to the special requirements, such as operational modes and phases which influence the system. This paper presents a more detailed wireless sensor network to check against the application requirements concerning QoS, reliability, and lifetime. An avionics application example is presented.

Analysis and validation using simulation is a helpful tool in systems engineering, but requires in-depth knowledge of various aspects of the system itself, the used model class(es), an appropriate software tool, and sometimes software engineering. Usually, this expertise is spread over a number of team members, and thus the development of a simulation-based system design tool is not a simple task. This paper presents a framework enabling the rapid development of extensible and reusable simulation-based applications. It supports an agile, iterative, evolutionary, and architecture-centric software development process. The design of the framework together with its components as well as the corresponding software development process is described. As an example, an environment for the configuration and analysis of wireless sensor network applications in the aeronautic domain is presented, which has been designed and implemented based on the proposed environment.

The cloud computing paradigm is considered as the next-generation of IT technology. It is also the internet based technology, where the users can share resources among the enormous cloud service provider, such as cloud partners and cloud vendors. Cloud computing makes high quality of service and high availability, so that users can simply access to prefer cloud with internet device. This makes many advantages and drawbacks for the users to create and store data in the cloud service provider. One is the data management and software may not be fully trustworthy in the cloud, therefore the security is an important aspect of quality of service. The purpose of this article is to concentrate on cloud data storage security and to manage the user's data in the cloud by Implementation of kerberos authentication service. I believe this novel article is the background for the next opportunity of growing the cloud security.

In this paper, we propose a modification method of color image, for a given region in the image, to obtain the image in which the region shows the highest saliency. Generally, it is thought that the most important part of an information system that assists human activities is a natural interface with human. In addition, eye-gaze information strongly reflects the human interest or their attention. Therefore, a gaze-based interface is promising for future practical applications. In particular, if we can smoothly guide the user's visual attention toward a target without interrupting their current visual attention, the usefulness of the gaze-based interface will be highly enhanced. In order to realize a novel interface based on visual attention, we propose a modification method for color image based on visual saliency map. The proposed method iteratively modifies the intensity and color so that the saliency inside the specified region increases while that outside the region decreases. This iteration is carried out until we obtain the image in which the specified region is most salient over the entire image. With the image obtained in this way, we can smoothly attract the user's visual attention to the specified region, without any interruption to the user's gaze. We evaluated the proposed method by a gaze measurement system and subjective experiments. As a result, we confirmed that the user's visual attention is indeed attracted toward our specified region without uncomfortable feeling.

Evaluation of C and P Factors in Universal Soil Loss Equation on Trapping Sediment: Case Study of Santubong River

引用

Journal of Water Resource and Protection 2013年第12期5卷 1149-1154页

作者： Kelvin K. K. Kuok Darrien Y. S. Mah P. C. Chiu Department of Civil Engineering Faculty of Engineering University of Malaysia Sarawak Kota Samarahan Malaysia Department of Information System Faculty of Computer Science and Information Technology University of Malaysia Sarawak Kota Samarahan Malaysia Faculty of Engineering Computing and Science Swinburne University of Technology Sarawak Malaysia

Universal Soil Loss Equation (USLE) is the most comprehensive technique available to predict the long term average annual rate of erosion on a field slope. USLE was governed by five factors include soil erodibility factor (K), rainfall and runoff erodibility index (R), crop/vegetation and management factor (C), support practice factor (P) and slope length-gradient factor (LS). In the past, K, R and LS factors are extensively studied. But the impacts of factors C and P to outfall Total Suspended Solid (TSS) and % reduction of TSS are not fully studied yet. Therefore, this study employs Buffer Zone Calculator as a tool to determine the sediment removal efficiency for different C and P factors. The selected study areas are Santubong River, Kuching, Sarawak. Results show that the outfall TSS is increasing with the increase of C values. The most effective and efficient land use for reducing TSS among 17 land uses investigated is found to be forest with undergrowth, followed by mixed dipt. forest, forest with no undergrowth, cultivated grass, logging 30, logging 10^6, wet rice, new shifting agriculture, oil palm, rubber, cocoa, coffee, tea and lastly settlement/cleared land. Besides, results also indicate that the % reduction of TSS is increasing with the decrease of P factor. The most effective support practice to reduce the outfall TSS is found to be terracing, followed by contour-strip cropping, contouring and lastly not implementing any soil conservation practice.
