Title:	AN IMPROVED ADAPTIVE AND DYNAMIC HYBRID AGILE METHODOLOGY TO ENHANCE SOFTWARE PROJECT SUCCESS DELIVERIES
Author:	SEENIVASAGAM MOHANARAJAH, DR MARZANAH A. JABAR
Abstract:	Context: There has been a growing interest in the usage and adaptive ramifications within the broad spectrum of agile methodologies and its current trend as an alternative to traditional methodologies has not been widely accepted. Whilst a lot of hype has been seen since its introduction in 2001 with the Agile manifesto where delivery success was promised, software practitioners still appear to be weary as unfavourable usage perceptions dominate the software industry and the transition appears to be a formidable task. Project success and failure scenarios have been researched but the factors that establish these are still widely inconclusive and elusive creating more interest and emphasis for embarking on further research. This paper highlights and investigates the relationship between agile software development methodologies and the success and failure scenarios prevalent in the software industry. Objective: To provide new success and failure causes and roots to a new adaptive and dynamic hybrid agile methodology that could further enhance software delivery success with more frequent use of agile methodologies in a reliable manner. Method: The methodology used is the Evidence-Based Software Engineering (EBSE) research and practice. Additionally, the Systematic Literature Review (SLR) method was also incorporated as it provided a rigorous review and synthesis of research results. In analysing the reviewed data, we have used the Analytical Hierarchy Process (AHP) method as it provided a clear approach in attaching priorities to recommended solutions. Results: Through a review of a set of research articles on project management history, its disciplines, its relative misunderstood and with the inconsistencies in the adoption and use of agile methodologies, it has been shown that barriers still exist and the strategies of removing these obstacles and transforming them into catalysts, while been investigated and developed, still appears to be a challenge. Agile methodologies work when a broader spectrum of perceptive adaptations and a new set of dynamic critical success factors, especially when a new methodology which incorporates these catalysts for a set of project activities is developed. Contribution: The study has contributed in proposing a new set of success and failure causes and the roots to a new agile methodology from the analysis and findings. These would be useful for researchers and software practitioners who are interested to do studies on the further adoption and use of existing agile methodologies or to tailor agile methodologies as hybrids versions in the future. Conclusion: Success and failure scenarios are the mainstream derivative constructs of project delivery studies in terms of the moving forward in achieving higher project success rate. Issues with stakeholders were the major areas of concern as success and failure contributors. Other important factors were organisational culture and methodology, which needed equal attention as gaps still prevailed and at times festered to its own disadvantage. The most interesting find was that these contributors were equally important whether we used traditionally formal methods or moved to agilitic methods. This also explains the flat success rate for software projects over the last 5 years as we probably reached a point where we have been addressing areas in terms of causes and were not specifically trying to weed out the areas independent and applicable to the software industry. We recommend that a dynamic approach both to the causes and the methodology is the answer as the software industry does not sit still in todays’ ever changing user demands and expectations. Environments with a dynamic methodology, which encompasses a dynamic set of critical success causes as its inception based on a set of dynamic success indicators, is the key answer. The dynamic success (and failure) factors, indicators and the derived methodology are recommended from our study. This we feel should be the approach for all new and future research.

Title:	OPTICAL POWER ATTENUATION OF LONG DISTANCE OPGW IN MALAYSIA
Author:	M. F. M. SALLEH, Z. ZAKARIA
Abstract:	Thousands of kilometres of Optical Ground Wire (OPGW) have been installed by electrical utility companies for two main purposes which are telecommunication and grounding. As the demand of optical fibres keep increasing to fulfil the needs for long distance communication that is immune to weather, telecommunication companies prefer to lease the extra fibres from electrical utility companies. Unfortunately, bend of optical fibre contribute to the loss and attenuate the optical power. High optical power attenuation found after several months of cable installation and caused the system to be interrupted. In this paper, the attenuation of optical fibres of long OPGW is monitored and discussed. The monitoring activities have been done on installed OPGW cable belongs to an electrical utility company, Tenaga Nasional Berhad (TNB) of Malaysia to determine the attenuation of optical power in 10 months.

Title:	MODIFIED VERTICAL HANDOFF DECISION ALGORITHM FOR IMPROVING QOS METRICS IN HETEROGENEOUS NETWORKS
Author:	V.VINOTH, M.LAKSHMI
Abstract:	In 4G networks, the meshing of WiMAX and WLAN has been a tough task. Issues regarding intermeshing of WIMAX and WLAN networks during vertical handoff have to be analyzed. Two interconnected networks such as WIMAX and WLAN has been proposed. Our proposed scheme provides better connectivity between fixed and mobile stations. In our proposed framework, two heterogeneous networks have been interconnected with each other and vertical handoff occurs between the two networks. A modified vertical handoff decision algorithm has been designed to calculate the bandwidth in WLAN and WIMAX networks. Packet delay is also calculated in modified algorithm. By calculating the bandwidth and packet delay, QOS metrics have been achieved by increasing the bandwidth and reducing the packet delay. Ad hoc network is the combination of wireless nodes without any infrastructure. It follows decentralized. Our proposed system improves the bandwidth and packet delay.

Title:	A PARALLEL SCHEDULING SEQUENCE OF GF (P) EDWARDS COORDINATES COMPUTATION FOR ECC
Author:	QASEM ABU AL-HAIJA
Abstract:	Elliptic curves cryptography (ECC) algorithm is well-known powerful approach of implementing public key cryptography created by Victor Miller and Neil Koblitz. ECC is a modular arithmetic based algorithm that includes modular inversion operation in its computation, which is considered as one of the heaviest operations that can be performed by the coprocessor. Implementing ECC with projective coordinates avoided the use of inversion by replacing it with a number of parallel multiplications. A parallel hardware scheduling of ECC based Edward's projective coordinates over prime finite field (GF (p)) will be studied in this paper to perform ECC doubling operation by using parallel hardware units. The analysis showed that parallelizing Edward's projective coordinates enhanced the performance factor by even three times over the serial design as it gives a considerable enhancement for the security against power/time attacks.

Title:	THE TASKS ALLOCATION BASED ON THE PRE-ESTIMATION OF THE PROCESSING TIME IN THE CLOUD ENVIRONMENT
Author:	YOUSSEF FAHIM, ELHABIB BEN LAHMAR, EL HOUSSINE LABRIJI, AHMED EDDAOUI
Abstract:	The Cloud computing has reduced the performance and profitability of the materiel and software resources. These challenges were solved by several load balancing algorithms between the virtual machines of the data centers. In fact, we find three main points of research in this article: Data center: It receives queries from clients of Cloud service to run them, using its own virtual machines in a sequential or parallel way. Sharing resources, is one of the main characteristics of the data center in the Cloud computing. Virtual machine (VM): Is a virtual device that has some performances determined by the Cloud provider. Such as memory storage capacity and the performance of its processor for the processing of tasks desired by the data center. The load balancing algorithms: they select the virtual machines in a data center for a new allocation of tasks, according to the predetermined metrics in each algorithm. Generally, we find two types of algorithms, static and dynamic. But, there is a problem when it comes to the current load of each virtual machine. In this paper, we propose a new improvement of the load balancing by our algorithm «pre-estimated processing time», that allows cloud service providers, to improve the performance, availability and maximize the use of virtual machines in their data centers. The key point of our improvement, it’s that take into account, the current load of the virtual machine of a data center and the pre-estimation of the processing time of a task before any allocation.

Title:	FEATURE SELECTIONS AND CLASSIFICATION MODEL FOR CUSTOMER CHURN
Author:	SYAFIQAH NAFIS, MOKHAIRI MAKHTAR, MOHD KHALID AWANG, M. NORDIN A.RAHMAN, MUSTAFA MAT DERIS
Abstract:	As customers actively exercise their right to change to a better service and since engaging new customers is more costly compared to retaining loyal customers, customer churn has become the main focus for one organization. This phenomenon affects many industries such as telecommunication companies which need to provide excellent service in order to win over the competition. Several models were developed in previous research using various methods such as the conventional statistical method, decision tree based model and neural network based approach in predicting customer churn. Several experiments were conducted in this research for feature selection and classification from selected customer churn dataset to compare its usefulness among the different feature selections and classifications using a data mining tool. The results from the experiments showed that the Logistic Model Tree (LMT) method is the best method for this dataset with a 95% accuracy enhanced using neural network from previous research.

Title:	AN ASSESSMENT OF CANCER PATIENTS PERFORMANCE USING SOCIAL NETWORKS: A TASK TECHNOLOGY FIT PRESPECTIVE
Author:	MARVA MIRABOLGHASEMI, NOORMINSHAH A. IAHAD
Abstract:	Cancer related social network communities have the potential to prepare an interactive environment where the virtual relationships among cancer patients can be established. However, current research into the assessment of cancer patients’ performance using Social Network Sites (SNS) continues to be limited. There is still a lack of considering situational factors such as task and technology characteristics. The aim of this paper is to use Task Technology Fit (TTF) Theory to assess the performance of cancer patients using SNS. Based on purposive sampling, questionnaires were distributed to 178 respondents in two hospitals and four cancer support groups in Peninsular Malaysia. The results indicate that cancer patients’ performance in using SNS was determined directly by fit between the characteristics of task and technology.

Abstract:	Attenuation of GSM, GPS and personal communication signal leads to poor communication inside the building using regular shapes of energy saving glass coating. Thus, the transmission is very low. A brand new type of band pass frequency selective surface (FSS) for energy saving glass application is presented in this paper for one unit cell. Numerical Periodic Method of Moment approach according to a previous study has been applied to determine the new optimum design of one unit cell energy saving glass coating structure. Optimization technique based on the Genetic Algorithm (GA) is used to obtain an improved in return loss and transmission signal. The unit cell of FSS is designed and simulated using the CST Microwave Studio software at based on industrial, scientific and medical bands (ISM). A unique and irregular shape of an energy saving glass coating structure is obtained with lower return loss and improved transmission coefficient.

Title:	DENIAL OF SERVICE ATTACK DETECTION USING TRAPEZOIDAL FUZZY REASONING SPIKING NEURAL P SYSTEM
Author:	RUFAI KAZEEM IDOWU, RAVIE CHANDREN M. ZULAIHA ALI OTHMAN
Abstract:	Although ‘Intrusion’ is considered to be a bitter pill to swallow due to the havoc it unleashes on the cyber space, but it has become a household name to cyber-security experts because it appears to rebuff all possible solutions! Consequent upon this, there have been unrelenting efforts to reduce its negative impacts to the lowest ebb by the introduction of various Intrusion Detection Systems (IDS). Meanwhile, Spiking Neural P (SN P) system, a variant of Membrane Computing (MC), has proved to be a versatile class of distributed parallel computing model which embeds the idea of spiking neurons into P systems. Therefore, in this work, we have explored trapezoidal Fuzzy Reasoning Spiking Neural P (tFRSN P) system, which is an extension of SN P system in attack detection. Specifically, the focus is on detecting Denial-of-Service (DoS) attack with emphasis on SYN (synchronize) flood. Consequently, KDD Cup benchmark dataset was used for evaluation in series of experiments conducted. While we obtained very low False Negatives (FN) and False Positives (FP) of 0.02% and 0.25% respectively, the True Positives/Negatives were equally very high. These results have further lent credence to the fact that MC and indeed SN P system are yet-to-be tapped goldmine as far as Intrusion Detection is concerned.
