Abstract— Speech technology and systems in human computer interaction have witnessed a stable and remarkable advancement  over the last two decades. Today, speech technologies are commercially available for an unlimited but interesting range of tasks. These technologies enable machines to respond correctly and reliably to human voices, and provide useful and valuable services. Recent research concentrates on developing systems that would be much more robust against variability in environment, speaker and language. Hence today’s researches mainly focus on ASR systems with a large vocabulary that support speaker independent operation with continuous speech in different languages. This paper gives an overview of the speech recognition system and its recent progress. The primary objective of this paper is to compare and summarize some of the well known methods used in various stages of speech recognition system.

Abstract— The foundation of Model Driven Architecture (MDA) approach is creation of models. MDA life cycle begins from Computation Independent Model (CIM) and ends with code. Object Management Group (OMG) explains various models and their relations, but it does not specify clearly how to create these models and which models to use for representation them. In this paper,
we focus on CIM level. CIM is the highest level of abstraction in MDA and it has high reusability in practice. In this paper, we present a method for generating CIM using artifacts and concepts of RUP methodology. Our proposed method presents a CIM that covers both aspects of CIM include business model and requirement model and it can transform into a complete Platform Independent Model (PIM). Proposed method is highly acceptable by experts.

Keywords- MDA; CIM; RUP; Business Model; Requirement Model; Use Case Model.

Abstract— We present a new approach to the matching of 2D shapes using XML language and dynamic programming. Given a 2D shape, we extract its contour and which is represented by set of points. The contour is divided into curves using corner detection. After, each curve is described by local and global features; these features are coded in a string of symbols and stored in a XML file. Finally, using the dynamic programming, we find the optimal alignment between sequences of symbols. Results are presented and compared with existing methods using MATLAB for KIMIA-25 database and MPEG7 databases.

Abstract – Many clustering algorithms with different methodologies are subjected to be common techniques and main step in many applications in the computer science world. The need of adapting efficient clustering algorithm increases in critical applications (i.e. wireless sensors networks). Utilizing the Fuzzy Logic power; Fuzzy C-mean (FCM) clustering has a major role
in most clustering applications. But in many cases, the result of FCM is considered to be non-complete clustering strategy. This paper adapted the FCM algorithm to enable of generating clusters with equal sizes. Also, scattered points that are located far away from all clusters are grouped out of clusters. Another modification is to localize specific points that have ability to locate in more than one cluster; hence this has a non-negligible importance in some fields such as cellular communications.

Keywords – Fuzzy C-Mean; Clustering; Euclidean Distance.

Abstract— Vehicle queue in the traffic light based link quality in wireless networks often optimizes their performance by real time measuring the quality of intelligent traffic light management system. However, measuring and describing link-quality is a challenging task due to the nature of residential area in Bandar Baru Bangi. This paper proposed the aspects of link-quality measurement in realistic networks to be taken into consideration when designing a LOS for wireless system. The objective of this study is to present the vehicle management based quality control to maximize the probability of successful transmissions while minimizing the end-to-end delay. The study involved the traffic junction parameters requirement, lane changing and traffic signal
responding logic with detailed traffic networks implementation experiences. By analyzing the statistical properties of link-quality, such as received signal strength and packet transmission rates, the statistical distribution across different links status were predicted. In addition, the default of signal strength mainly found to be the reason for the irregularity in the packet received values
provided the measured link-quality and statistical analysis to better adapt their link behavior.

Keywords- traffic light; link quality; LOS; signal strength; packet transmission rates.

Abstract— In this information age many institutions have resorted to using information systems to handle most of the business processes. However, well as many of them spend huge resources on implementing information systems to solve their problems, many times the value for money invested in putting up these information systems is not optimally realized because more often
these systems fail to fully address the problems they were intended to solve. This article examines how organization such as a University, can use both e-management and LEAN management principles to improve their business processes and the overall enterprise architecture; with an aim of improving the business process at the University through redesigning the current enterprise
architecture based on Service oriented Architecture (SOA). It is hoped that the redesigned enterprise architecture knitted around the above principles will go a long way in improving the satisfaction levels on the side of students, and other stakeholders like staff and senior management, reduce on wastage, improve on agility of business processes, increase productivity on the side of employees and thus result into happy managers and students. The methodology was qualitative which involved conducting indepth interviews with students and senior managers from business process owners’ side, data owners and senior managers at the Information Technology Division of the University. The following findings and recommendations were based on a single case study conducted at University X where students are not satisfied with the current quality of service they receive from the University’s hostel management.

Keywords- Enterprise Architecture; Enterprise Integration; Business Process Improvement; Service-Oriented Architecture; EManagement Principles.
