Title:	CURRENT TRENDS OF COMMUNICATION SYSTEMS IN MEDICAL MONITORING SERVICES: THE CASE OF WSNS OPERATING SYSTEM DESIGN
Author:	MOHAMMED JAMAL AL-MANSOR, KOK BENG GAN
Abstract:	Wireless communication services are now in use right across the world and in particular in the health sector. The need for quality healthcare means that different individuals have to cooperate through sharing of information and discussion of patient management. This has led to increased need for quality information and communication technologies that support such cooperation. Unfortunately, a lot of interest and investment in information technology has largely focused on communication systems with very little focus on systems that apply to medical field. Even adoption of such simple technology as wireless sensor technology has not taken root in the medical field. This paper therefore presents studies and reviews of different networks in relation to the OS design of WSNs for monitoring.

Title:	WEIGHTING CUSTOMERS DATA FOR MORE ACCURATE SHORT-TERM LOAD FORECAST
Author:	SYLVIA JANE A. SUMARAUW, SUBANAR, EDI WINARKO, RETANTYO WARDOYO
Abstract:	Disruption of the electricity supply service to the customers or the overload primary energy usage is often caused by load forecast fault. This fault, especially the short-term load forecast (STLF), occurs by unpredictable factors. One of these factors is weather effect in a load centre.The application of the load forecast model in the electrical system with the use of energy trend on the demand site, influenced by fluctuations of the weather, requires weather data from the affected electrical system areas. However, weather stations in Indonesia are limited and do not represent the electrical system areas. Although STLF research used many methods has been widely conducted in many countries, Indonesia, especially PLN (national electrical company, the only electricity provider in Indonesia) has not undertaken it. Moreover, the studies that clearly explain the coverage areas of the electrical system and how to obtain the weather data have not yet been conducted. This paper discusses a method in obtaining the weather data through weather observation sites represented the load centres in the coverage areas of electrical system. The result shows that the application of the method improved the forecasting performance.

Title:	AN EFFICIENT FAST HEVC ENCODING TECHNIQUE
Author:	AHMAD A. MAZHAR
Abstract:	HEVC video coding standard uses a structure of flexible Coding Unit (CU) quad tree. This flexibility increases the coding efficiency and allows the standard to achieve better rate-distortion performance compared to its prior H.264/MPEG-4 AVC. The improvement of coding efficiency came at the cost of high encoding complexity. This paper presents a fast algorithm to reduce the encoding complexity by an early termination decision with reference frame selection. Experimental results for seven standard video sequences show that the proposed algorithm can save up to 53.79% of the encoding time compared to the original HM14. Different video sequences with different frame rates, quantization parameters and resolutions were used in the experiments. The paper also presented the effect of changing resolutions, frame rates and bit rates on compression efficiency for both HM and the proposed algorithm. In comparison with the original software, the proposed algorithm presents significant improvement and time saving. In addition, the proposed algorithm outperformed two of the best state of the art proposed methods.

Title:	SUPPORTING DATA CONSISTENCY USING EFFICIENT INVALIDATION SCHEME IN MOBILE ADHOC NETWORKS
Author:	THARANI VIMAL, DR.S.A.SAHAYA ARUL MARY
Abstract:	Caching frequently accessed data in mobile nodes is an effective technique to improve the performance in Mobile Adhoc NETworks (MANETs). Cache invalidation plays a vital role in maintaining the data consistency among source and cache nodes. The conventional cache invalidation techniques are unsuitable for MANETs due to frequent disconnections and resource constrained mobile nodes. This work proposes the Data-update Pattern-aware Invalidation Prediction in caching (DPIP). The proposed DPIP consists of Access Frequency aware Data Classification, Cache Update Prediction based Dynamic Invalidation and Adaptive Query Searching in MANET. Selecting the most popular data to replicate in multiple mobile nodes is critical in caching. The DPIP divides the data into different classes according to the frequency of data access and replicates the most popular data in multiple locations. By applying the prediction at an update time of a particular data using prior information, the DPIP adaptively adjusts the invalidation interval to the cache nodes of particular data. It effectively balances the access delay and cache consistency. The Adaptive Query Searching enables the cache node to utilize the Query Directory nodes (QDs) and look for a cache node through broadcasting the route discovery packets to QDs. Thus, the DPIP caching successfully increases the data availability and improves the lifetime. Finally, the proposed system is implemented on Destination-Sequenced Distance-Vector (DSDV) routing. The simulation demonstrates a better performance of DPIP than the existing caching system in terms of cache hit ratio, throughput, routing overhead and access delay.

Title:	KURTOSIS-BASED PROJECTION PURSUIT FOR SIGNAL SEPARATION OF TRADITIONAL MUSICAL INSTRUMENTS
Author:	ATIK WINTARTI, YOYON K. SUPRAPTO, WIRAWAN
Abstract:	Signal separation is a substantial problem in digital signal processing. The objective of signal separation from a musical composition is to decompose the composition into signals of individual musical instruments. One method that can be used is Projection Pursuit (PP) that similar with Independent Component Analysis (ICA). PP can determine source signals by projecting the data to find the most non-Gaussian distribution. In this paper we propose a method based on kurtosis as a criteria to determine non-Gaussianity. We use Mean Square Error (MSE) and Signal-to-Noise Ratio (SNR) to evaluate the accuracy of signal separation. We conducted an experiment on a synthetic and real signal mixture of traditional musical instruments i.e. Javanese Gamelan. The result showed that the minimum value of MSE for separation signal using Kurtosis-based PP (K-PP) is 1.02 * 10-5 lower than FastICA and PP. Meanwhile, the maximum value of SNR with the proposed method is 42.13 dB higher than the others.

Author:	NUR SYADHILA CHE LAH, AB RAZAK CHE HUSSIN, NOR ZAIRAH AB RAHIM, ABDELSALAM H.BUSALIM
Abstract:	Intention to purchase in existing online business practice is learned through observation of information display by online seller. The emergent growth of persuasive technologies currently holds a great potential in driving a positive influence towards consumer purchase behavior. But to date, there is still limited research on implementing persuasion concept into the recommender system context. Drawing upon the principle design of persuasive system, the main purpose of this study is to explore social learning advantages in creating persuasive features for E-Commerce recommender system. Based on Social Cognitive Theory, the influence of personal and environmental factors will be examined in measuring consumer purchase intention. In addition, dimensions of social learning environment are represented by observational learning theory and cognitive learning theory. From those reviews, this study assumed that social learning environment can be created based on attentiveness, retentiveness, motivational, knowledge awareness and interest evaluation cues of consumer learning factors. Furthermore, the persuasive environment of recommender system is assumed to have positive influence towards individual characteristics such as self-efficacy behavior, perceived task complexity and confused by over choice. Findings from those reviews have contributed to the development of a research model in visualizing social learning environment that can be used to develop a persuasive recommender system in E-Commerce and hence measures the impact towards consumer purchase intention.

Title:	MODEL-DRIVEN DECISION SUPPORT SYSTEM FOR ESTIMATING NUMBER OF AMBULANCES REQUIRED DURING EARTHQUAKE DISASTER RELIEF OPERATION
Author:	EBRAHIM ESMAILI, HALINA MOHAMED DAHLAN, MOHAMMAD ISHAK DESA
Abstract:	Most of human life has been encountered danger due to natural disasters nowadays. One of these natural disasters that endanger human lives and which causes lot of damages is earthquake. A proper emergency response after an earthquake happening is important and has high priority in earthquake emergency management to reduce number of damages. Decision making for critical resources in the phase of response, is one of the main concerns for managers. Ambulance, as one of the critical resource that can help to reduce earthquake losses and costs, needs to be planned. Confusion in the number of victims in the early stages of earthquake, access complexity to the required data of different organizations by the pressing time, complicated nature of estimation, diversity of models and limitation of time for decision making are the main problems associated with estimating ambulances during earthquake disaster which makes estimation too difficult. In addition, there is a call for research in determining the number of required ambulances during earthquake emergency management, due to high error in estimating the number of ambulances in the current methods, which leads to unnecessary expenses and thereby helping to ensure that disaster sites are not overcrowded with emergency workers impeding each other's effectiveness. Such complexity suggests the introduction of Decision Support System (DSS). More accurate estimation of the number of required ambulances using a decision support system can help managers to speed up the process of decision making and thus reducing error and costs. Since the number of ambulances needed during a disaster is directly proportional to the number of victims requiring hospital treatment and in order to reach the first objective of this study, factors determining the number of human casualties in earthquake disaster i.e. population, modified Mercalli, age, time, building occupancy and gender are selected as the most relevant factors which have high probability in creating human casualties. The collected data from various relevant sources is used in proposing the model of this research. After testing different approaches, Fuzzy rule-based approach is being used, after defining the rules for each aforementioned factors and optimization is conducted in order to minimize the error for estimating the number of human casualties. Finally, by using de Boer formula and obtained number of human casualties, the number of required ambulances is estimated accurately. The results indicate that the error is decreased by more than 50% in the proposed method. A prototype of Model-Driven Decision Support System was developed based on the proposed model that can be used to aid emergency response planners for their decision making process prior to take any action during earthquake emergency management.

Title:	A SYSTEMATIC REVIEW ON DATA SECURITY AND PATIENT PRIVACY ISSUES IN ELECTRONIC MEDICAL RECORDS
Author:	AMJAD MAHFUTH, JASPALJEET SINGH DHILLON, SULFEEZA MOHD DRUS
Abstract:	The adoption of Electronic Medical Records (EMR) in healthcare organizations has numerous benefits to physicians, patients, and healthcare services. However, unresolved security and privacy concerns pertaining to patient information cause relatively low adoption of EMR by health institutions. Safeguarding large amount of sensitive health data at different locations and forms proves to be a major challenge of EMR. In this paper, a Systematic Literature Review (SLR) is presented to (1) identify the security and privacy concerns in the adoption of EMR by health organizations and (2) to analyze the existing solutions in addressing the identified concerns. A total of 393 papers were found in this regard. After careful study and the removal of duplicate papers and screening of studies, 15 papers which met the inclusion criteria were selected for the review. This review will help researchers to be aware of the privacy and security concerns of EMR and the existing solutions. The review revealed that the security and privacy issues related to EMR are inadequately addressed. This study indicates that the technical and financial supports are insufficient to overcome the security issues of EMR, and thus, the success factors and security culture should be investigated. Developing countries meet many challenges in adopting EMR, especially due to the lack of security policy and background infrastructure. Hence, novel solutions such as best practice guidelines with respect to security and privacy are necessary to aid successfully adoption EMR.

Title:	QUEUING MODEL APPROACH FOR ENHANCING QOS OF WEB SERVICES
Author:	Ms. SUNDHARAM. R., Mrs. LAKSHMI. M
Abstract:	In the distributed and parallel computing system, the availability of web service is increased by replicating the web services over physically distributed servers. For the large scale applications single server cannot fulfill the request of services, it leads to slow down the response time which is merely equivalent to unavailable service. In order to increase the availability of web service and minimize the response time, we have proposed Framework for Enhancing the Availability of Web Services. It uses Poisson distribution and queuing model  to predict the future arrival rates and future response time respectively. Based on predicted results, server availability factor (SAF) and attributes value of Replication Matrix (RM), the decision is taken dynamically to replicate the specific service on appropriate host before the response time violates the SLA time. Hence the requested web service is made available to client service continuously with increased availability. A simulated test environment has been created to evaluate the performance of framework and test results are compared with existing models. The comparisons indicate that our framework provides greater performance. Thus, our framework maintains the response time of web service within expected SLA response time even during peak load and it significantly improves the availability of web service.

Title:	PROVIDING SECURITY TO PUBLISH / SUBSCRIBE SYSTEM USING STRONG NETWORK CRYPTOGRAPHIC TECHNIQUES AND TWO TIER ENCRYPTION
Author:	AANCHAL RAI, MRS. MAYA SHELKE - BEMBDE
Abstract:	There are different types of distributed systems existing in this world which needs the massive amount of information to be transferred between them and along with it comes the need of secure communication between different parties. Publish subscribe system is the communication archetype for information broadcasting in huge distributed system. Selling a product and merchandising it, isn't a cup of tea for each manufactures, thus all manufactures are probing for various third party product promoters like promotion agencies, dealers or third party brokers. For a business to explore, brokers are playing a very crucial role. However loyalty of the brokers cannot be assured. So to handle this problem many broker less systems are been proposed for publish-subscribe system in distributed pattern. However most of these systems have not completely succeeded in achieving privacy of the data over the transactions. So proposed system forwards an idea of preserving the confidentiality of information by key generation for each publish/ subscribe transactions and the keys are randomly generated based on the event details and subscriber data using reverse circle cipher[10] and two tier encryption.

Title:	OPTIMIZED ROUTE FORMATION TECHNIQUE (ORFT) FOR DYNAMIC MANETS
Author:	SNEHALATHA N, PAUL RODRIGUES
Abstract:	Ever since the evolution of MANETs there has been continuous development in the research endeavors that improve the communication efficiency for the same. Although there has been so much research till date, there are so many of the MANET research issues still prevalent and hindering the smooth communication. One such issue is ambiguity and haste during route formation that not only reduces the success rate of the communication, but sometimes has a totally negative effect on the rest of the system. To avoid the packet loss during route formation and effective data delivery end-to-end, we propose a node Optimized Route Formation Technique (ORFT) using a single probabilistic method and individual node history of operations (Node Quality Factor - NQF). The ORFT method uses a simultaneous node metric evaluation process and end-to-end route evaluation process to find the best routes to destinations. Performance is analyzed using the network simulator.

Author:	MAIZATUL AKMA MOHAMAD, SHATTRI MANSOR, NOORDIN AHMAD, WAN AZIZUN WAN ADNAN, ISLAM MUHAMMAD WALI
Abstract:	The rapid growth of Halal product market creates high demand for the logistic system to ensure the reliability of product during the transportation process. However, due to contamination, pilferage and chance of breakage in the supply chain, the reliability of the current status of halal product has been questioned that leads to the initiative of developing a new tracking system to monitor the movement of the product. Aiming at monitoring and reducing the possibility of cross contamination that might occur during the transportation process, the Halaltracer tracking system was developed using the combinations of Global Positioning System (GPS) and geofence algorithm. The Halaltracer tracking system is significantly contributing in terms of automatic detection on the spatial activity taken during the halal products shipment process. Apart from providing spatial information about the delivery session and the route taken, the system also can detect the possibility of cross contamination by monitoring in real time the stopping of vehicles using a ray casting algorithm applied to the geofence technique used in the system. A functional prototype device with a web based interface for reporting function was completely built and tested in different kind of situation. The testing showed that the proposed model was capable of presenting a report of tracking which compliant the requirement of managing Halal product. In conclusion, these Halaltracer system will improve the traceability of Halal product during transportation by focusing on the Halal part thus, adding the credibility of consumer confidence in consuming the Halal products.

Title:	KNOWLEDGE MANAGEMENT BEST PRACTICE IN HIGHER LEARNING INSTITUTION: A SYSTEMATIC LITERATURE REVIEW
Author:	HALIJAH ISMAIL, RUSLI ABDULLAH
Abstract:	This systematic literature review (SLR) aims to identify the Knowledge Management (KM) Best Practice components in the KM Model proposal for Higher Learning Institutions (HLI) environment. The KM Best Practice components identified from this paper will be referring in the future study to verify the effectiveness of the components to be the best practice for KM. A SLR of KM Best Practice to identify and define the components of Best Practice from the KM models was conducted recently. 179 articles included in the literature review were extracted based on the exclusion criteria and only retained 71 related reviews. The review of published papers of conference and journals’ articles shows the components of Best Practice in KM are basically divided into two aspects which is the soft aspect and the hard aspect. The literature evidence the lacks of combination of these two aspects into an integrated model decelerate KM Best Practice to fully throttle in the organization. The scenario leads to the immaturity of the HLI towards the implementation of KM System. The first steps of identifying the attributes to measure the components from the models in the literature will led to the definition of the KM Best Practice component for the higher learning environment as concluded in this Systematic Literature Review.

Title:	CULTURAL DIMENSIONS OF MALAYSIAN TEENAGERS AND THEIR RELATIONSHIP WITH INTERFACE DESIGN
Author:	ZURIDA ISHAK, AZIZAH JAAFAR
Abstract:	This study aimed to identify the relationship between cultural dimensions of adolescents in Malaysia and their tendencies with interface design of computer applications. Numerous studies have used Hofstedes cultural dimensions to design user interfaces and tested their application in many countries. However, test results in Asian countries such as China and Taiwan are not significant because the cultural dimensions are unsuitable for these countries. Therefore, this study will use the cultural dimensions of Malaysian society to test the relationship with interface components tendency. Respondents of different races and religions, with different family incomes, and from urban and rural areas are selected from six secondary schools. Pearson correlation analysis with a significance level of 0.05 is used to determine the relationship between cultural dimensions, namely, harmony, relationship, hierarchy, collectivism, shame, polychronic time, high-context communication, and religion, and the use of interface components, namely, metaphor, mental model and navigation, interaction, and appearance. Result shows that four cultural dimensions have a significantly positive relationship with the interface components (hierarchy, religion, polychronic time, and collectivism) with an r value of more than 0.1.

Title:	CHANNEL ESTIMATION USING EXTENDED KALMAN FILTER WITH SLICED MULTI MODULUS BLIND EQUALIZATION ALGORITHM (SMMA)
Author:	SANJAY KUMAR KVS, DR. B. L. MALLESWARI
Abstract:	Multiple-Input Multiple-Output (MIMO) systems use multiple number of antennas on the both sides of transmission and reception to achieve high spectral efficiency. Channel impulse responses are regularly thought to be steady over a block or packet. These blocks are assumed like stationary on channels. Though, for communications in a high mobility and fading channel, the assumption will cut down the system performance. Here we concentrate on channel estimation for a MIMO system with Orthogonal Frequency Division Multiplexing (OFDM) transmission technique. The system, estimates the channel matrix at the receiver with Extended Kalman Filter (EKF). After the estimation, we employ low cost OFDM-MIMO soft data detector. The soft outputs of soft data detection are fed back to sliced multi-modulus algorithm (SMMA) for an improved channel estimation. Iteratively using EKF and SMMA overall performance has been achieved. Convergence characteristics of EKF-SMMA is simulated using MATLAB and it is shown that it gives better steady-state performance with regard to inter-symbol interference (ISI) & Bit-error rate. It additionally demonstrates that the researched calculation shows reduced steady-state misadjustment contrasted with the best reported multi-modulus algorithm (MMA).

Title:	PROBABILISTIC ARABIC PART OF SPEECH TAGGER WITH UNKNOWN WORDS HANDLING
Author:	Mohammed Albared, Tareq Al-Moslmi, Nazlia Omar, Adel Al-Shabi, Fadl Mutaher Ba-Alwi
Abstract:	Part Of Speech (POS) tagger is an essential preprocessing step in many natural language applications. In this paper, we investigate the best configuration of trigram Hidden Markov Model (HMM) Arabic POS tagger when small tagged corpus is available. With small training data, unknown word POS guessing is the main problem. This problem becomes more serious in languages which have huge size of vocabulary and rich and complex morphology like Arabic. In order to handle this problem in Arabic POS tagger, we have studied the effect of integrating a lexicon based morphological analyzer to improve the performance of the tagger. Moreover, in this work, several lexical models have been empirically defined, implemented and evaluated. These models are based essentially on the internal structure and the formation process of Arabic words. Furthermore, several combinations of these models have been presented. The POS tagger has been trained with a training corpus of 29300 words and it uses a tagset of 24 different POS tags. Our system achieves state-of-the-art overall accuracy in Arabic part of speech tagging and outperforms other Arabic taggers in unknown word POS tagging accuracy.
Keywords:	Part of Speech Tagger, Arabic Language, Unknown Word Guessing.

Title:	EXPLORING FACTORS THAT INFLUENCE CUSTOMER ENGAGEMENT IN VALUE CO-CREATION IN HIGHER EDUCATION INSTITUTIONS USING ONLINE PLATFORMS
Author:	NABIL HASAN, AZIZAH ABDUL RAHMAN
Abstract:	Higher Education Institutions (HEIs) can be described as a container that encompasses strong knowledgeable minds and experienced individuals. It is one of the service sectors comprised of a huge number of individuals who are attached for life with Higher Education Institutions and possess resources of knowledge, experience and competency. These valuable resources are considered to be sources of innovative performance, best service quality and better community transformation. By engaging such brilliant minds in value co-creation, either with internal or external customers of these HEIs, it is believed that this engagement will help HEIs to maintain better service quality, attain reputable positions and contribute to enhance community transformation. However, the task to engage large numbers of HEIs customers in co-creation of value is not easy to be achieved without in-depth exploration of how to accomplish and sustain such engagement. Special effort is taking place to engage the inner and outer HEIs community in value co-creation process through online platforms. Yet, the level of customers engagement still low and poor. The aim of this research is to explore factors that impact HEIs customers to be engaged in any form of value co-creation through the online platforms, and to introduce a holistic value co-creation model that helps universities and other HEIs to engage customers in value co-creation activities through any means of effective online platforms. A qualitative method is adopted by interviewing ten HEIs experts from four reputable Malaysian universities. Data are collected, analyzed and synthesized with support of Nvivo10 software. Value co-creation conceptual model is established and the results reveal that there are several factors that have an impact on customer engagement in the value co-creation in HEIs. According to the nature of value co-creation and the context of this research, factors are summarized into three classifications: organizational factors that represent HEIs provider aspects and these factors are the predominant among other aspects. Then technological factors that represent the online platform characteristics and the personal factors that represent customer aspects.
