Abstract— A real-time system is software where the correct functioning of the system depends on the results produced by the system and the time at which these results  are produced. The main objective of this study is to show the importance of real-time  system as an application that uses computer system in the human life. Since it helps  to control vital and dangerous aspects, that otherwise can not be controlled. 
 The motivation for this study is to avoid fire occurrence and smoking habits in certain  places.  Since by using this system the place and time of event can be determined in short  period. For that reason, the need for using real-system raised.

Keywords- Real time system; Fire and Smoking Control System; Very High speed Integrated Description Language (VHDL).

Abstract— Source code analysis does not provide enough information for the program understanding activities. Understanding object oriented software systems during software maintenance are difficult and take a considerable amount of time and cost. In software maintenance perspective reverse engineering process extracts information to provide visibility of the object oriented components and relations in the software that are essential for maintainers. Various tools have been developed to help maintainers undergo this process. One such tool is reverse engineering object Oriented program tool. In this paper, we provide a framework environment for object oriented programs. The framework focuses on the technical side of maintaining object-oriented program. This paper will discuss the development of the tool and highlight a scenario to show the viability of the tool by providing querying and browsing facilities.

Keywords – Software Maintenance, Reverse Engineering, Object Oriented.

Kriging Interpolation Filter to Reduce High Density Salt and Pepper Noise

Abstract—Image denoising is a critical issue in the field of digital image processing. This paper proposes a novel Salt & Pepper noise suppression by developing a Kriging Interpolation Filter (KIF) for image denoising. Gray-level images degraded with Salt & Pepper noise have been considered. A sequential search for noise detection was made using kk window size to determine non-noisy pixels only. The non-noisy pixels are passed into Kriging interpolation method to predict their absent neighbor pixels that were noisy pixels at the first phase. The utilization of Kriging interpolation filter proves that it is very impressive to suppress high noise density. It has been found that Kriging Interpolation filter achieves noise reduction without loss of edges and detailed information. Comparisons with existing algorithms are done using quality metrics like PSNR and MSE to assess the proposed filter.Keywords- Image enhancement; image denoising; noise reduction; image restoration; salt & pepper noise; kriging.

Abstract—Widely used in development of web services, Scrum contributes to agile service development, reducing the Time To Market (TTM) and increasing the profit to service providers. Caring for dynamic requirement changes and incremental development of web services are other advantages of employing Scrum for development of web services. However there are several problems with this methodology limiting its applicability to web service development. Scrum overlooks precise documentation of development activities to increase the development speed. Nonetheless this approach negatively affects the quality of the web services through incorporating imprecision and lack of tractability into the development process. On the other hand security as a quality attribute has always been one of the most important concerns of the web service development. To care for  of the web service we always need to incorporate security analysis and design into the development life cycle.   Although there have been some attempts to care for analysis activities within the Scrum iterations, it is not clear yet how to achieve this automatically through the Scrum processes. On the other words careful engineering of security into the overall system analysis and design is often neglected. In this paper we propose a security-enhanced version of scrum i.e. Secure Scrum (S-Scrum) to accommodate security analysis and design activities within the Scrum. We have modified the scum process to care for security analysis and design through the standard Scum processes. The validity of the proposed approach is verified through formal modeling and description of the process steps. We propose a grammar for formal description of Scum process model.  Keywords-Scrum; Web Service; Security; Automata.

Exploring the Educational Benefits of Blogs to Help Non-Malay pupils in Malay Language Learning

Abstract— Language learning environment plays an important role in the acquisition of students’ second language, and its imperative grows more and more crucial when students learn another language (e.g., when non-Malay students are learning the Malay language). Some students have been observed to be unmotivated and even less willing to speak in the intended language due to prevailing learning environment they are entrenched in. In view of this current learning milieu, educators should seek new, novel learning environments that appeal to students, especially the non-Malay students, in learning the Malay language. Blog is one of the alternatives that could be tapped on as ‘blogging’ promotes the ‘authenticity’ sought by teachers to retain students persistently in language learning, as well as to allow students to experience diverse, rich cultures. Therefore, teachers should integrate blogs in their writing classes in well-planned learning activities that would gradually improve pupils’ writing skills, particularly the non-Malay students. Being a new concept as a learning tool in Malaysia, blogs provide many new opportunities for teachers to explore their efficacy in Malay language writing. Premised on this need, this paper discusses some of the affordances of blog in supporting the second language teaching and learning, especially in writing skills.

Keywords- blog; second language learning; non-Malay, Malay Language; writing skills; learning platforms.
