Author:	MOHAMMED AL-ALI , NOR ERNE NAZIRA BAZIN , SITI MARYAM SHAMSUDDIN
Abstract:	Customer satisfaction is critical to retail success. Concentrating on customer satisfaction has become a major goal in retailing industry, especially in grocery retail. This work examines the key determinants of customer satisfaction in grocery retailing and measure the link between store attributes and customer satisfaction. In addition, it aims to find out the effect size of these determinants on overall customer satisfaction in an emerging market, namely Malaysia. For this purpose, an extensive dataset from 313 shoppers who had carried out their purchase in different type of grocery stores has been analyzed. Using Partial Least Squares-SEM (PLS-SEM) analysis method, we show that three determinants (‘‘monetary value’’, ‘‘service and convenience’’, and ‘‘store quality image’’) have a direct impact on customer satisfaction. However, the weight that each factor shows is different. Results may help managers of grocery stores in Malaysia to develop and implement more successful relationship marketing strategies.

Title:	EFFICIENT TECHNIQUES FOR PREDICTING SUPPLIERS CHURN TENDENCY IN E-COMMERCE BASED ON WEBSITE ACCESS DATA
Author:	VERONICA S. MOERTINI, NIKO IBRAHIM, LIONOV
Abstract:	Electronic supplier relationship management (e-SRM) is important in order to maintain strong, long lasting and beneficial relationship between e-commerce firms and their suppliers. One important function of e-SRM is to predict suppliers who tend to churn such that early “treatment” can be given. In the e-commerce systems that involve suppliers as the websites users, predicting suppliers’ churn tendency can be based on analyzing their frequencies in accessing the e-commerce websites. Our proposed techniques include data warehouse design (supporting the data collection and preprocessing) and unsupervised algorithms that analyze the preprocessed bitmaps of time series data representing suppliers website access from time to time. Having bitmaps as inputs, our proposed algorithms are efficient (the time complexity is O(n)) as proven with our experiments. In experimenting with real world data of an e-commerce system selling hotel rooms, our techniques produce output of supplier segments where each segment has certain churn level tendency and need specific treatment.

Title:	REVIEW OF QUALITY OF SERVICE IN ROUTING PROTOCOLS FOR WIRELESS SENSOR NETWORKS
Author:	ABDULLAH BAMATRAF, MOHAMMAD SHAFIE BIN ABD LATIFF, YAHAYA COULIBALY, AHMAD M. KHASAWNEH
Abstract:	Rapid innovative improvements in wireless communication technology have revolutionized wireless sensor networks (WSNs). A WSN is comprised of self-ruling sensors that are distributed spatially to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion, or pollutants, and to pass this information through the network to a main area. Sensor nodes in wireless sensor networks experience the ill effects of resource constraints, such as energy deficits, buffers, and bandwidth issues. The expanding demand for real-time services in WSN applications means that interest in quality of service (QoS)-based routing has risen. Offering consistent QoS in sensor networks creates considerable challenges. In real time applications, it is important to deliver data as soon as it is sensed. If the network has multiple real and non-real-time applications, its ability to manage them will be challenging due to different requirements. In this study, we investigate QoS-based routing protocols for WSNs. Metrics of analysis are end-to-end delay, congestion, energy efficiency, and reliability. The aim of the study is to identify the limitations of relevant papers and show research direction in routing. This will not only help new comers to the field of WSN but also will ease the tasks of WSN researchers in developing appropriate routing solutions for WSNs.
Keywords:	QoS, WSN, End-to-end Delay, Congestion, Energy Efficiency, Reliability, Heterogeneity.

Title:	INTENSIVE FIXED CHUNKING (IFC) DE-DUPLICATION FOR SPACE OPTIMIZATION IN PRIVATE CLOUD STORAGE BACKUP
Author:	M.SHYAMALA DEVI, V.VIMAL KHANNA, M.SHAHEEN SHAH
Abstract:	Cloud Storage provides users with abundant storage space and make user friendly for immediate data access. But there is a lack of analysis on optimizing cloud storage for effective data access. With the development of storage and technology, digital data has occupied more and more space. According to statistics, 60% of digital data is redundant, and the data compression can only eliminate intra-file redundancy. In order to solve these problems, De-Duplication has been proposed. Many organizations have set up private cloud storage with their unused resources for resource utilization. Since private cloud storage has limited amount of hardware resources, they need to optimally utilize the space to hold maximum data. In this paper, we are going to discuss the flaws in the existing de-duplication methods and introduce new methods for Data De-Duplication. Our proposed method namely Intensive Fixed Chunking (IFC) De-duplication which is the enhanced File level de-duplication that provides dynamic space optimization in private cloud storage backup as well as increase the throughput and de-duplication efficiency

Author:	ABDELFETTAH MIRAOUI, LOTFI MERAD, SIDI 1MOHAMED MERIAH
Abstract:	Localization and Reconstruction of homogenous objects from electromagnetic scattered fields have been shown to be of great importance, because of their various applications in many areas such as medicine, biology, geophysics and other sciences. In this paper, we propose a computational method for detection and localization of the object for medical application (breast cancer). The proposed technique is based on the use of artificial neural network ANN. A spherical tumor was created and at arbitrary locations in a breast model using an EM simulator. Bow-tie antennas were used to transmit and receive Ultra-Wide Band (UWB) signals at 4GHz. A training and validation sets were constructed to train and test the ANN. A very optimistic results have been observed for early received signal components with the ANN model. Hence, the proposed model is very potential for early tumor detection to save human lives in the future.

Title:	AN ENHANCEMENT ALGORITHM USING GABOR FILTER FOR FINGERPRINT RECOGNITION
Author:	EINAS ALMARGHNI AZZOUBI, ROSZIATI BINT IBRAHIM
Abstract:	Fingerprint recognition is being widely applied in the personal identification for the purpose of high degree of security by matching processes between two human fingerprints. Many different techniques have been proposed to have a satisfactory fingerprint identification. The widely used minutiae-based representation does not utilize a significant component of the rich discriminatory information available in the fingerprints. Local ridge structures cannot be completely characterized by minutiae. Further, minutiae-based matching has difficulty in quickly matching two fingerprint images containing different numbers of unregistered minutiae points. We introduced an enhancement algorithm using Gabor filter based matching to capture both local and global details in a fingerprint as a compact fixed-length Fingercode. The improved filtering used to feather extraction in our proposed algorithm with eight different directions. The last step of our proposed algorithm is fingerprint matching, which is based on the Euclidean Distance (ED) between the two corresponding Fingercodes. The proposed algorithm can be personalized according to the value of Euclidean Distance (ED) and threshold (TH). If the ED is less than TH or equal to zero, it means that the two fingerprint images came from the same person. We compared our proposed algorithm (enhanced) with algorithm (without enhanced). The values of false acceptance rate (FAR), false reject rate (FRR) and equal error rate (EER) are lower than the algorithm (without enhanced). Also, the result based on proposed algorithm are also presented and based on the result, it gives higher accuracy and recognition rate.

Title:	PORTFOLIO SELECTION USING THE CAT SWARM OPTIMIZATION
Author:	HAMZA KAMILI, MOHAMMED ESSAID RIFFI
Abstract:	The portfolio selection is a discipline in finance interested in the optimization of the investment represented by a mixed quadratic programming problem. The approach of this paper to studying the portfolio selection problem is the implementation of the metaheuristic cat swarm optimization , a method inspired from the behavior of different felines and characterized by two modes: the seeking and the tracing mode; the seeking mode is when a cat is at rest observing its environment ,the tracing mode is when the cat is hunting. In this article, we have adapted this method to the cardinality constrained efficient frontier (CCEF) compared to the data of mean return and risk obtained by the unconstrained efficient frontier (UEF) for five indexes markets and we have obtained efficient results.

Title:	IDFP-TREE: AN EFFICIENT TREE FOR INTERACTIVE MINING OF FREQUENT SUBGRAPH PATTERNS
Author:	MOHAMMAD H. NADIMI-SHAHRAKI, MARYAM TAKI, MOHAMMAD NADERI
Abstract:	Recently, knowledge extraction from transactional graph databases by mining frequent subgraph patterns has become an interesting research topic. One of the important challenges in this topic is the situation called interactive mining in which the minimum support threshold can be frequently changed to find proper frequent subgraph patterns. Obviously, running the mining method from scratch is very costly. Therefore, in this paper, an efficient tree called IDFP-tree is proposed to develop our previous two-layer model for interactive mining of frequent subgraph patterns from transactional graph databases. The proposed tree constructs the mining model separated from the mining process. Thus, when the minimum support threshold is changed, there is no need to reconstruct the mining model, and only the mining process must be rerun. The experimental results show when the mining model is constructed by IDFP-tree, it can be frequently used and the total runtime of interactive mining of frequent subgraph patterns can be reduced.

Author:	LAU WENG LOON, MAMUN BIN IBNE REAZ, KHAIRUN NISA’ MINHAD, NOORFAZILA KAMAL, WAN MIMI DIYANA WAN ZAKI
Abstract:	High performance phase frequency detector (PFD) is one of the key modules in high speed delay-locked loop (DLL). The operation of DLL depends on the performance of its detector. The demand for the reduction of power dissipation in CMOS design is a challenge in order to optimize circuit power consumption. A low power dynamic pseudo-PMOS PFD is proposed to make DLL system more reliable. In this work NOR gate of typical TSPC PFD is replaced with a low power dissipation pseudo-PMOS AND gate built of 3 PMOS transistors. Pseudo-PMOS AND integrated into proposed TSPC PFD to run maximum frequency at 1G Hz with 1.8 V input power supply. This proposed PFD has been implemented in Mentor Graphics 0.18 μm CMOS process technology and consumed 163.36 µm2 active layout area with 206 nW total power dissipation will further trim down the total cost of the DLL.
