Title:	ENHANCED PLANTED(ℓ,D) MOTIF SEARCH PRUNE ALGORITHM FOR PARALLEL ENVIRONMENT
Author:	SATARUPA MOHANTY, BISWAJIT SAHOO
Abstract:	The Identification of inimitable patterns (motif) occurring in a set of biological sequences could give rise to new biological discoveries and has been studied considerably due to its paramount importance. In the field of bioinformatics, motif search is the vital problem for its application in the detection of transcriptional regulatory elements and transcription factor binding sites (TFBS) which are crucial for the knowledge of drug design, human disease, gene function etc. Many aspects of the motif search problem have been identified in the literature. One of them is the planted (ℓ, d)-motif search problem. In this paper, we propose a parallel extension of the existing PMSPRUNE algorithm along with two additional features: those are neighbor generation on a demand basis and omitting the duplicate neighbor checking with the help of a bit vector implementation. The experimental result shows, the proposed multicore algorithm in C, handles the problem for larger d value with fix length ℓ with a speed up more than twice, without any additional requirement of space on a 2.4GHz PC with 4GB RAM.

Author:	A.BALOUKI, A.ETTABBAA, A.ELHASSNAOUI, M.MABROUKI, Y.BALOUKI, M.FAKIR
Abstract:	The development of mechatronic systems imply different actors with different specialties and therefore use different concepts. To have good communication between the different stakeholders and permanent integration of sophisticated services, we propose a unified approach based on the reference model for open distributed systems. These include an enterprise viewpoint, which focuses on the objectives and policies of the enterprise that the system is meant to Support. To do this in the first place we developed a specification language to define the mechatronics enterprise viewpoint. For that, We focus on the expression of mechatronic enterprise policies that govern the behavior of mechatronic enterprise objects .We develop a mechatronic policy language. After, we propose to use a subset of the UML as a concrete notation for specifying mechatronics enterprise viewpoint. We illustrate the ideas in the paper with a case study that expose an enterprise specification of a braking system of a robot.
Keywords:	Mechatronic Design, Different Stakeholders, RM-ODP, Enterprise Viewpoint, Mechatronic Policy Language.

Author:	ALAA KAMAL, M.N. MOHD. WARIP, MOHAMED ELSHAIKH
Abstract:	The Energy efficient being the main constraint for wireless sensor networks (WSN) became an important area of interest for various researches in WSN. A lot of work on conservation power consumption at a different layer of protocols is present till date, of which energy conservation at a Medium access control (MAC) layer is catching a lot of attention. Generally, The energy consumption it is a main critical factor affecting the operational lifetime of individual nodes and the entire network. The energy consumption in medium access control (MAC) for wireless sensor network (WSN) affected by many reasons collision, overhearing, Idle Listening, Control Overhead. The optimizing power consumption is a challenge to prolong lifetime network. In this paper, we minimize the power consumption of the B-MAC protocol for wireless sensor network (WSN) by using Differential Evolution (DE) algorithm. Simulation experiments are carried out on the discrete event simulator OMNET++ for the purposes of this research paper. Moreover, the experimental analysis shows the improvement the energy consumption of (DE-BMAC) can be conserved about (58.6%) more than B-MAC without affect the network performance.

Title:	ARABIC HANDWRITTEN WORD CATEGORY CLASSIFICATION USING BAG OF FEATURES
Author:	AYMAN AL-DMOUR, MOHAMMED ABUHELALEH
Abstract:	Human writing is highly variable and inconsistent, and this makes the offline recognition of handwritten words extremely challenging. This paper describes a novel approach that can be employed for the offline recognition of handwritten Arabic words. Through conceptualizing each word as single, inseparable objects, the proposed approach aims to recognize words in accordance with their complete shape. This paper describes the bag-of-visual-words method that has been effectively employed for the purposes of classifying images. The study consisted of four main stages. First, a set of image patches were sampled for the purposes of training, and a speeded up robust features (SURF) descriptor was then used to characterize them. Following that, the bag-of-visual-words model was employed through constructing the K-means clustering algorithm. A histogram of each whole world was developed and this operated as the image feature vector. This was employed to train the support vector machine classifier, which was then able to effectively distinguish between handwritten words. Finally, the effectiveness of the proposed method was tested using a sample of Arabic words extracted from the IFN/ENIT database and the results indicated that the bag-of-visual-words approach represents a promising method of recognizing and classifying handwritten Arabic words. The best and average recognition rates of the proposed method are 85% and 75% respectively.

Title:	NORMALIZED STEP SIZE APPROACH TO SIGNAL PROCESSING BASED ON LAGGED CROSS-CORRELATION OF PROBABILITY
Author:	NAMYONG KIM, ANNA ANDONOVA, MINGOO KANG
Abstract:	The signal processing algorithms based on the lagged cross-correlation of probability (LCCP) have been considered very effective in the multipath environment with impulsive and DC noise coexisting in visual light/power line communication (VLC/PLC) systems for energy saving intelligent buildings. To meet the demand for higher data rates and more complicated sensor node configuration, in this paper, performance enhancement methods by employing a normalized step size in the LCCP-based algorithms which are sensitive to the scaling of system input contaminated with impulses and DC noise are proposed through the analysis of the behavior of optimum weight and the role of magnitude controlled input (MCI) on influence of large errors. The normalized LCCP algorithm with the step size normalized with the averaged power of the current MCI shows a faster speed by about 5 times and has a lower minimum mean squared error by about 3 dB than the conventional LCCP algorithm in blind equalization simulation for indoor VLC/PLC channel models.

Title:	VALIDATION OF A PROPOSED DASHBOARD MODEL FOR RESEARCHERS IN SOCIAL RESEARCH NETWORK SITES
Author:	SITI HAWA APANDI, RUZAINI ABDULLAH ARSHAH
Abstract:	The Social Research Network Sites (SRNS), online platform used by researchers, have huge amounts of information that would sometimes overwhelm the researchers. However, they need a dashboard as a tool to provide awareness on current information that are related to their fields of research; thus, the proposed dashboard model for the researchers in the SRNS is designed. This paper aims to discuss the validation of the dashboard model for the researchers in the SRNS by conducting an interview session, which is conducted among the researchers that consists of academic staffs and postgraduate students from the universities in Malaysia. After being shown the dashboard model and the accompanying mock-up prototyping representing the dashboard model, the researchers were asked to gauge their satisfaction on the dashboard model and their intention of using the model. The outcome of the interview is that the researchers are satisfied with and intended to use the dashboard model, while suggesting some enhancement of the dashboard components to be included in the dashboard model. The dashboard model can be used by a developer of the SRNS as a guideline to develop a better online platform for the researchers by including the dashboard in the SRNS.

Title:	SYSTEMATIC LITERATURE REVIEW OF E-COMMERCE IMPLEMENTATION STUDIES
Author:	DEBORAH LIBU PARIS, MAHADI BAHARI, NOORMINSHAH A. IAHAD, WAIDAH ISMAIL
Abstract:	E-Commerce implementation is a crucial process for organization to make it successful and beneficial. As a consequence, intensive research works in the area of e-Commerce implementation from a diverse range of views and findings have been studied by many researchers. However, the aspect of Business-to-Customer (B2C) e-Commerce implementation has yet been undertaken in an understandable manner in the context of a full life cycle of information systems development. This paper provides a systematic literature review of existing research studies on e-Commerce implementation to discover the extent focus of work based on theme in the implementation phases: pre-implementation, during implementation and post implementation. Sixty five (65) selected primary research studies have been analysed on the basis of implementation phase theme, research approach and research area. The results show that majority papers discussed B2C e-Commerce in the pre-implementation phase (49%) and applied quantitative approach (63%) as the most popular research method. Two other implementation phases namely during implementation phase and post implementation phase has not been sufficiently addressed in the existing literature. Furthermore, existing literature have significantly addressed factors related to e-Commerce implementation but were not mapped to the appropriate implementation phases. These factors list remains on surface without clear direction in which e-Commerce implementation process is crucial for organizations. Thus, through a systematic literature review this study suggests that more research is needed for understanding the complex process of e-Commerce implementation in a more holistic manner. In addition, there is a need for study to screen these factors to a particular and more accurately “map” in the process of e-Commerce implementation.

Title:	CONCEPTUALIZATION OF E-GOVERNMENT INTEGRATION STUDIES
Author:	FATMA MOHAMED AL-BALUSHI, MAHADI BAHARI, AZIZAH ABDUL RAHMAN, HASLINA HASHIM
Abstract:	E-government integration has gained interest of researchers from different perspectives. Some have studied it from organizational perspective; other researchers have proposed models and recommended solutions for technical problems in some systems. Other researchers deal with integration interoperability or information sharing and often focus on integration in other domains (e.g., supply chain management). Yet, not many efforts are dedicated towards e-Government integration conceptualization. This paper renders a panoramic overview on the past development, present status and future trends of e-Government integration. This comprehensive and systematic assessment on existing literature is hoped to serve as taxonomy for navigating and understanding the research advancements towards e-Government integration. Based on a content analysis method, this paper identifies e-Government integration stakeholders, useful theories applied, and research methods employed. Our findings suggest that there is a strong need for a better understanding of what are valuable and compelling conceptions of e-Government integration and who are the stakeholders involved. The lack of e-Government integration research is now recognized; despite much research on the e-Government integration is far from being understood.

Author:	SITI ZAKIAH BT. MELATU SAMSI, HASMIDA JAMALUDDIN, AZLEEN SHABRINA MOHD NOOR, SITI NURUL HUDA MOHD, SALEHA ABDULLAH
Abstract:	In line with the advancement of internet technology, e-Tourism has become an important platform for promotional, marketing and product development of tourism products and services. It provides a way to perform relevant transactions as well as mechanism to interact with potential tourists. E-Tourism has become popular among Muslim tourists since they are also referring to the websites to search for travelling information. As a Muslim, the travelling information that they seek should comply with the need of the religion such as Halal food, prayer time, religious places etc. However it is still difficult to find a specific and comprehensive website that provide necessary information to the Muslim tourists due to the lacking in the knowledge about information quality. Information quality is an important element in e-commerce which is one of the Information System (IS) success factors dimension based on IS success Model introduced by [1]. Companies that sell products or services online must ensure that the information provided on their website has certain criteria of information quality which may influence the purchasing decision of the customers. 138 respondents amongst Muslim tourists participated in the survey that was conducted both online and offline, which the data was then analyzed using SPSS software. This paper will discuss, (i) The information that is expected by Muslim tourists available on Islamic e-Tourism websites; and (ii) The relationship between information quality with usefulness and information satisfaction. The result has proven that Islamic content, timeliness, legitimacy, relevancy, reliability, Islamic design, consistency, accessibility and security are significant in predicting usefulness whereas for information satisfaction, only relevancy, Islamic design and security and privacy are significant. This study will benefit Islamic e-Tourism businesses, website owners, developers and designers by providing a guideline on the expected information that should be available on the website that serve Muslim tourists and how to make sure that the website fulfill the requirements needed by them.

Title:	SIMPLE AND EFFECTIVE METHOD FOR SELECTING QUASI-IDENTIFIER
Author:	AMANI MAHAGOUB OMER, MOHD MURTADHA BIN MOHAMAD
Abstract:	In this paper, a new method to select quasi-identifier (QI) to achieve k-anonymity for protecting privacy is introduced. For this purpose, two algorithms, Selective followed by Decompose algorithm, are proposed. The simulation results show that the proposed algorithm is better. Extensive experimental results on real world data sets confirm efficiency and accuracy of our algorithms.
