Title:	CYBER SECURITY FOR CYBER PHYSCIAL SYSTEMS: A TRUST-BASED APPROACH
Author:	SAQIB ALI, RAJA WASEEM ANWAR, OMAR KHADEER HUSSAIN
Abstract:	Cyber- Physical Systems (CPS) consist of a combination of different embedded subsystems, which work independently of each other and also interact with the external environment. Such embedded systems operate in the presence of inherent uncertainty, context dependencies and adversarial certainty arising from both the cyber and physical worlds. Security is one of the key concepts to shield the CPS environment and different embedding devices in order to have a reliable and secure communication platform. There are many security approaches and methods proposed and implemented globally in order to secure CPS, along with areas such as social engineering, security standards, vendor control, as well as access control implementation, etc. However, in addition to these areas, another important concept, namely trust, is significant in ensuring secure and reliable communications in CPS. In the current state-of-the-art, none of the existing approaches discusses the issue of a secure, trust-based CPS. Thus, to address this shortcoming, in this paper, a two-tier blanket approach is proposed consisting of internal and external layers of trust among different entities to create reliable and secure CPS. This trust-based framework improves the confidence of secure entities joining the CPS system and also builds relationships among entities, thereby increasing the security protecting the formed CPS from outside threats and attacks.

Title:	EXPERIMENTAL EVALUATION OF TCP CONGESTION CONTORL MECHANISMS IN SHORT AND LONG DISTANCE NETWORKS
Author:	Mudassar Ahmad, Md Asri Ngadi, Mohd Murtadha Mohamad
Abstract:	Originally TCP was designed for early, low bandwidth, short distance networks, so Standard TCP did not utilize the maximum bandwidth in today�s high bandwidth network environments. Therefore a lot of TCP congestion control mechanisms also known as TCP variants have been developed for today�s long distance high bandwidth networks. In this paper the experimental results evaluating the performance of TCP Reno, HighSpeed TCP, BIC TCP, TCP CUBIC and Compound TCP in short and long distance high bandwidth networks are presented. Results show that TCP CUBIC shows the highest performance in goodput whereas TCP Compound shows the highest performance in protocol fairness and TCP friendliness as compared to the other stat of the art congestion control mechanisms.
Keywords:	Congestion Control Mechanism, Protocol Fairness, TCP Friendliness, Goodputs.

Title:	RISK ASSESSMENT OF IT GOVERNANCE: A SYSTEMATIC LITERATURE REVIEW
Author:	NORAINI CHE PA, BOKOLO ANTHONY JNR, ROZI NOR HAIZAN NOR, MASRAH AZRIFAH AZMI MURAD
Abstract:	Risk assessment (RA) is one of the main activities in risk management of IT governance. Basically, IT governance is a process or a procedure that involves evaluating and directing the plans for the use of ICT to support the organization and monitoring the achievement of these plans. The risks that may emerge during the implementation of IT governance must be properly assessed to ensure its success. In general, risk assessment in IT governance is focusing on the essential process to aid all relevant parties involved in IT implementation from both the technical and services aspects. Many studies related to IT risk assessment and risk assessments of IT governance have been reviewed based on a systematic method which is called Systematic Literature Review (SLR). Based on this approach, all previous studies related to this title can be analyzed systematically. Based on the same framework, this paper presents the results of the systematic reviews on the concept, process, framework, model and challenges of risk assessment of IT governance. In general, the findings from this review indicate that RA requires a more holistic consideration on numerous limitations and issues.
Keywords:	Risk Assessment, IT Governance, Systematic Literature Review.

Title:	HYBRID STATISTICAL RULE-BASED CLASSIFIER FOR ARABIC TEXT MINING
Author:	ABDULLAH S. GHAREB, ABDUL RAZAK HAMDAN, AZURALIZA ABU BAKAR, MOHD RIDZWAN YAAKUB
Abstract:	Text categorization is one of key technology for organizing digital dataset. The Naiv Bayes (NB) is popular categorization method due its efficiency and less time complexity, and the Associative Classification (AC) approach has the capability to produces classifier rival to those learned by traditional categorization techniques. However, the independence assumption for text features and the omission of feature frequencies in NB method violates its performance when the selected features are not highly correlated to text categories. Likewise, the lack of useful discovery and usage of categorization rules is the major problem of AC and its performance is declined with large set of rules. This paper proposed a hybrid categorization method for Arabic text mining that combines the merits of statistical classifier (NB) and rule based classifier (AC) in one framework and tried to overcome their limitations. In the first stage, the useful categorization rules are discovered using AC approach and ensure that associated features are highly correlated to their categories. In the second stage, the NB is utilized at the back end of discovery process and takes the discovered rules, concatenates the associated features for each category and classifies texts based on the statistical information of associated features. The proposed method was evaluated on three Arabic text datasets with multiple categories with and without feature selection methods. The experimental results showed that the hybrid method outperforms AC individually with/without feature selection methods and it is better than NB in few cases only with some feature selection methods when the selected feature subset was small.

Author:	MURIZAH KASSIM, MAHAMOD ISMAIL, MAT IKRAM YUSOF
Abstract:	This paper presents the development of a new scheme called Adaptive Throughput Policy (ATP) algorithm to control internet inbound throughput utilization in an IP-based network by considering traffic flows and their processing times. Real live inbound internet traffics collected from a Campus Network with Committed Access Rate (CAR) of 16 Mbps bandwidth allocations to internal users are analyzed. New mathematical model with identified parameters are derived and policies are simulated using Token Bucket theory control mechanism. Three main policies conditions called P1 which is controlled on 5% under threshold, P2 which is controlled on threshold rate and P3 which is controlled beyond 10% threshold are defined as filtered condition. ATP simulation evaluated throughput performance on the real live internet traffic. Result present achievement in throughput performance which includes Bucket Capacity, Bandwidth Saving and Processing Time for daily and weekly traffics. The findings show that ATP algorithm resulted in higher bandwidth saving and faster traffic process time in particular during under threshold (P1). Burst throughput are managed to control according to identified implement policies in the development system.

Title:	ENERGY EFFICIENT NODE DISJOINT MULTIPATH ROUTING TO IMPROVE WIRELESS SENSOR NETWORK LIFETIME
Author:	ABDULALEEM ALI ALMAZROI, MA NGADI
Abstract:	Some of the major challenges confronting wireless sensor networks are usually associated with scarcity of energy and resource limitations. In order to achieve efficient utilization of energy and increase the operational lifetime of the wireless sensor network while at the same time providing consistent packets delivery, energy efficient node disjoint multipath routing was recommended. In our method the node-disjoint multiple paths are discovered from the source node to the sink node. We make efficient utilization of the network paths by intelligently elect the most suitable paths for packet transmissions based on path cost calculation. The path cost calculation considers the number of hops, minimum energy node in the path and latency rate, As a result the best paths will select based on latest path cost. The structure of the control messages were shown in different categories. The fragmentation of data packets on node-disjoint multipath were also set-up through the network. Results through simulations investigated explains how EENDM accomplished better outcomes than DD and also N-1 multipath routing technique when compared with the benchmarks lifetime of network, control message overhead, consumption of energy node, Packet delivery ratio, and average packet delay.

Author:	DEDID CAHYA HAPPYANTO
Abstract:	Hybrid car on the drive system used in the study are two types of driving three phase induction motors and the Internal Combustion Engine (ICE) as a backup drive. On the second drive system is required movement drive transmission soft transition during the both movement of the drive. Therefore, techniques are required to control the electronic switch gear in the car drive transmission equipment. The control technique used is the PID Fuzzy control to synchronize the speed of the both the rotation speed driver, so that the resulting movement of the soft transmission electronic switch gear in the transmission. This step is done by setting the rotation speed of the ICE as a master and motor rotation speed as a slave, because the electric motor setup easier than setting ICE, so that adjusts the transmission shift is the speed of the electric motor. At the time of transfer will be an adjustment speed transmission electric motor and speed the ICE, then when synchronization is achieved with PID Fuzzy control techniques with modeling algorithms then proceed to shift the transmission. Prime mover is an electric motor car, but when the battery power is weak then the mover will make the shift the transmission into drive ICE. During Mover ICE work going through the generator will be charging current to the battery is fully charged then moved again to the transmission of electric motor drive, and so on. To get a better sync speed both mover speed then using the PID Fuzzy Self-Tuning control technique. The results show that the control PID Fuzzy appropriate when applied to the hybrid car because it has fast response and good autotuning on any change of mover car speed.

Author:	SITI ISTIANAH MAHDZUR, JUHANA SALIM
Abstract:	An Information Systems (IS) change to meet the changing organizational environment is crucial in e-Government (e-G) implementation to give it competitive advantage. Unfortunately research showed that though e-GIS implementation leveraged the IS integration concept, e-GIS does not using the benefits of resource integration to provide strategic information and reuse of knowledge to sustain. Aiming on the beneficial capabilities of e-GIS integration implementation to facilitate IS sustainability (ISS), this research revealed challenges and 15 factors contributing to the needs of e-GIS integration and identified 4 factors of e-GIS integration implementation that contribute to the ISS in organization. This study then suggests a comprehensive support of e-GIS integration implementation using Work System Theory, Diffusion and Innovation Theory and Knowledge Based Theory in organization and at the same time using benefit of ISS explained by Belief-Action-Outcome framework. The four prominent factors are business and systems stakeholder collaboration, organizational operation transformation and organizational memory system. This study also proposes an e-GIS integration implementation model towards ISS.

Author:	C. SUBASHINI, Dr. UMA RAJARAM, DR.S.RAVI
Abstract:	This papers discusses about reconfigurable system that allow online adaptation, whenever a fault occurs in the system. This is obtained by using FPGA that switches among Configurable Logic Block(CLB) automatically which has same features in an optimal manner. This reduces the time and complexity. Also the faulty CLB is tested for its output and if it matches with a desired output pattern, then it can be used instead of a spare so that the area efficiency improves. Automatic adaptation, selection of signals and controlling is obtained using ARM STM32 controller . Different modulation application is chosen to enumerate this reconfiguration by the controller.

Title:	A COMPARATIVE EVALUATION OF STATE-OF-THE-ART INTEGRATION TESTING TECHNIQUES OF COMPONENT-BASED SOFTWARE
Author:	ABUBAKAR ELSAFI, DAYANG N. A. JAWAWI, ABDELZAHIR ABDELMABOUD, AWAD ALI
Abstract:	In the last few years, component-based software has gained widespread notice and acceptance as a method that facilitates the development of existing large, complex, and very critical systems by integrating prefabricated small pieces of software called components. Component integration becomes an essential stage in the component-based software development Lifecycle. Therefore, testing components after integration is an important activity. Due to the unavailability of source code of integrated components and due to the lack of component information or documentations, integration testing becomes more difficult and very complex task. In the literature, different techniques have been proposed with the purpose of facilitating the integration testing of component-based software. In this paper, we study, classify, and evaluate some of the existing integration testing techniques and make a comparison in order to help in develop new, better and more efficient and effective techniques for integration testing of component-based software systems.

Title:	A REVIEW ON ONTOLOGY-BASED LABEL EXTRACTION FROM IMAGE DATA
Author:	AHMAD ADEL ABU-SHAREHA, MANDAVA RAJESWARI
Abstract:	Ontology-based label extraction is extensively used to interpret the semantics found in image and video data. Particularly, ontology-based label extraction is one of the main steps in object class recognition, image annotation, and image disambiguation. These applications have important roles in the field of image analysis, and as such, a number of variations of the ontology-based label extraction used in these applications have been reported in the literature. These variations involve ontology development and utilization, and can affect the applicability (e.g., domain- and application-dependency) as well as the accuracy of the output. Unfortunately, the variability aspect of this variation has neither been established nor tracked. Thus, the variations were not configured. A review of the ontology-based label extraction based on the input data, the utilized technique, and the type of utilized ontology is presented in this paper. The ontology-based label extraction is categorized based on two aspects, namely, the type of input data and the type of ontology used. These two aspects determine the type of the label extraction technique to be used. As a result, the relative advantages and disadvantages of each category are determined. The gaps and future research directions in this field are also highlighted.

Title:	AN EFFICIENT ADAPTIVE GENETIC ALGORITHM FOR VECTOR SPACE MODEL
Author:	WAFA' ALMA'AITAH, KHALED ALMAKADMEH
Abstract:	In this study, we propose to use an Adaptive Genetic Algorithm (AGA) aimed to enhance the performance of information retrieval under Vector Space Model (VSM) in both (Cosine and Dice similarity). Using the algorithm is aimed to improve the quality of the results of user's query and generate improved queries that fit searcher�s needs. Furthermore, we investigate and evaluate different fitness functions that reduce the search space and reduce the number of iterations needed to generate an optimized query. Traditional Genetic Algorithms (GA) use fixed values for crossover and mutation operators; and such values remained fixed during the execution of the algorithm. The adaptive genetic algorithm uses crossover and mutation operators with variable probability; which allows for faster attainment of improved query results. The proposed approach is verified using (242) proceedings abstracts (in Arabic) collected from the Saudi Arabian National conference.

Title:	IMPROVING KWH-METER PERFORMANCE AT PV ON GRID SYSTEM BY MULTIPLYING THE NUMBER OF SAMPLING SIGNAL
Author:	ISDAWIMAH, RUDY SETIABUDY, RIDWAN GUNAWAN
Abstract:	The PV system is integrated with a low-voltage power network requires an inverter to convert the generated DC voltage by PV systems into AC voltage, and kWh-meter to measure the energy delivered by PV systems to the power grid . The latest generation inverter uses high frequency switching method to reduce the dimension and to improve the efficiency of the inverter. However, this high frequency switching raises the harmonics distortion flowing into the power grid and kWh-meter, and cause significant measurement errors in digital kWh-meter. This study intends to overcome the measurement error by the method of adjusting the frequency of sampling signal in kWh-meter digital with the switching frequency of the inverter. First, kWh-meter tested with a variety of inverter switching frequency to obtain the minimum value of the switching frequency which affected the measurement results of digital kWh-meters. Then kWh-meter measurement results corrected by sampling the signal according to the switching frequency of the inverter. The proposed method is evaluated by simulation LAB-VIEW and confirmed by experimental results. The proposed method is able to maintain the performance of kwh-meters on inverter switching frequency in range 3kHz -150kHz.
