Authors: R.POORVADEVI , S.RAJALAKSHMI , S.RAMAMOORTHY

Abstract: All the companies are nowadays migrating their applications towards cloud environment, because of the huge reduce in the overall investment and greatest flexibility provided by the cloud. The Cloud provides the larger volume of space for the storage and different set of services for all kind of applications to the cloud customers. There is not much delay and major changes required at the client level. The large amount of user data and application results stored on the cloud environment, will automatically make the data analysis and prediction process very difficult on the different clusters of cloud. It is always difficult to process, whenever a user required to analyze the data stored on the cloud as well as frequently used service by other cloud customers for the same set of query on the cloud environment.The existing data mining techniques are insufficient to analyze those huge data volumes and identify the frequent services accessed by the cloud users.

2. SECURITY NETWORK WITH VIRTUAL PRIVATE NETWORK & (IPSEC) APPLICATIONS

Authors: AHMED A. SABEEH , DHARI KH ABEDULA

Abstract: Internet communication is largely based on TCP/IP protocols. The main design of TCP/IP is for trusted peers to communicate. IP Packets have no inherent security, and therefore it is relatively easy to forge the addresses of IP packets, modify the contents of IP packets, replay old packets, and inspect the contents of IP packets in transit. In this paper, we discuss how Internet Protocol Security (IPSec) is used for secured and encrypted communication between Internet hosts. IPSec is described as an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite[1]. According to Kent et al., it can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). To discussthe use of IPSec in an TCP/IP based network, we chose Virtual Private Network (VPN) as the application in describing how IPSec provides the platform for secure and encr

Abstract: With the advance in technology and the introduction of cloud computing, the usage of Internet application has been increased rapidly. In addition, the online storages with password protected such as Dropbox, Box Sync, Copy and Cloud Me are already available to all users. Hence, with a rapid development and introduction of this technology, the analysis on the hard drive has become obsolete in retrieving the information from those applications. The aim of this paper is to present an algorithm to track the sensitive information from online application for both active and exile process in the computer memory. The algorithm encompasses the signature search to find the possible processes in the memory, obtain the user and machine data and then some sensitive information with regard to the online application. The algorithm will be independent of address translation algorithm that has been frequently applied in the retrieving technique in the past.

Authors: HASAN SARWAR , MD. AKHTARUZZAMAN , MOHAMMAD SHAHADAT HOSSAIN CHOWDHURY

Abstract: Software Process Improvement (SPI) can help the software practitioners to enhance their capabilities in the field of software engineering. Various models have been proposed in order to improve software process framework. However, implementation of such modules often requires huge cost involvement. Small and Medium sized Software Enterprises (SMEs), in Bangladesh, naturally fail to introduce or adapt such frameworks. So it has become a need of time to observe the Software Process scenario as a part of research activity which will ensure smoother transition to improved Process Framework. In this paper, various practical models and their practices in various SMEs and the importance of SPI system are highlighted and analyzed. Survey has been conducted to assess Real life practices with a view to compare with Benchmarks like Capability Maturity Model Integration (CMMI).

6. A SYSTEMATIC REVIEW OF INTEROPERABILITY MODELS

Authors: REZA REZAEI , SAI PECK LEE , THIAM KIAN CHIEW

Abstract: Interoperability is the ability in which systems and enterprises could interrelate and incorporate to each other. With the purpose of improvement of interoperability between systems, an interoperability model isrequired. This study aims at reviewing existing research on interoperability models in order to identify a comprehensive interoperability model. In this review study, all of the existing models for interoperabilityare presented. The majority of the interoperability models focuses only on three of four interoperability types. The existing models are also not at a satisfactory level of development for improvement of interoperability between systems. Thus structuring interoperability models into one single comprehensive and complete interoperability model is necessary in order to ensure consistency and avoid redundancy. In addition, we need to identify metrics and properties to allow better development of interoperability between systems.

Authors: REZA REZAEI , SAI PECK LEE , THIAM KIAN CHIEW

Abstract: Various definitions have been defined for the word “interoperability”; in general however, “interoperability” is a property through which the systems and organizations can communicate and cooperate. In e-government domain to establish “interoperability” among the organizations, using a suitable “interoperability” framework is inevitable. Numerous frameworks have been proposed in e-government interoperability domain. Selecting a suitable interoperability framework as a reference from among the existing interoperability frameworks in e-government domain is a major challenge of great importance. This paper aims at investigating the present frameworks of interoperability in e-government domain and identifying a reference interoperability framework for this domain. The results of this study show that all the existing interoperability frameworks in the e - government domain have some drawbacks. Defining a comprehensive framework of interoperability in e-government domain is therefore inevita

Authors: JEGA ANISH DEV

Abstract: Since its introduction in 2009, Bitcoin, an open source, peer to peer, digital crypto currency has been growing in popularity and wide spread use. Growing attention, recognition by major financial institutions and high valued currency units (BTC) ascertains Bitcoin to a sturdy and ever increasing choice of currency. A public transaction log called the “Blockchain” keeps records of all committed transactions and Bitcoin ownership details, that is, addresses derived by cryptographic keys. Bitcoin mining, a process which results in the generation of new Bitcoins, is performed by miner operators for reception of incentives in the form of Bitcoins. This mining process is essentially operations of SHA-256 hashing of values in search of a hash digest smaller than a specific value. Once this winning hash has been discovered, a new block to Blockchain is added and BTC incentives are furnished by the Bitcoin network to the miner. This paper discusses methods of performing Bitcoin mining on non-c

12. UTILIZING WORDNET FOR INSTANCE-BASED SCHEMA MATCHING

Authors: AHMED MOUNAF MAHDI , SABRINA TIUN

Abstract: Instance-based matching is the process of identifying the correspondences of schema elements by comparing the instances of different data sources. It is used as an alternative option when the schema-based matching fails. Instance-based matching is applied in many application areas such as website creation and management, data warehousing, database design, and data integration. Many recent approaches focus on instance-based matching. In this paper, we propose an approach that utilizes WordNet-based measure for string domain by getting the similarity coefficient in the range of [0..1]. In previous approach, the regular expression is achieved with a good accuracy for numerical instances only and is not implemented on string instances because we need to know the meaning of string to decide if there is a match or not. The using of WordNet-based measures for string instances should guarantee to improve the effectiveness in terms of Precision (P), Recall (R) and f-measure (F). In this paper w

Authors: SAMER ATAWNEH

Abstract: Image-based steganography is the practice of embedding secret information into digital images with the intention to communicate the secret information. Embedding large sizes of secret information into digital images is one of the problems that image-based steganography encounters. The distortion of digital image increases with larger capacity, meaning that both are positively correlated. The latter makes image-based steganography fingerprints perceptually and statistically visible. In this paper, we propose a new spatial-domain steganographic scheme based on Bit-Plane Complexity Segmentation (BPCS). Experimental results reveals that the proposed algorithm offers better embedding performance compared with prior BPCS-based algorithms in terms of image quality and capacity.

Authors: GENG WAN , MINORU OKADA , TAKESHI HIGASHINO

Abstract: Diversity and data rate over multipath fading channels in wireless communication systems can be significantly enhanced by the combined use of orthogonal space-time block coding (OSTBC) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) techniques. However, to obtain the maximum benefits of the above schemes, the required antenna spacing at both the transmit and receive sideswill result in high-cost antenna deployments. Hence, the use of triple-polarized antennas appears to be a cost- and space-efficient alternative. In this paper, we model the triple-polarized MIMO channel and evaluate the error performance of OSTBC-MIMO-OFDM system using proposed channel model. Simulation result shows error performance improvement when using triple-polarized antennas in OSTBC-MIMO-OFDM systems compared to that of using spatially-separated uni-polarized antennas.

Authors: MINORU OKADA , TAKESHI HIGASHINO , RYAN PADERNA

Abstract: Integrated Services Digital Broadcasting for Terrestrial (ISDB-T) One-Seg is a Japanese standard for digital television specifically for mobile reception. It uses Orthogonal Frequency Division Multiplexing (OFDM) that provides robustness against multipath fading. A novel approach called Compressed Sensing (CS) has been implemented for estimating the Channel State Information (CSI). The CS improves the spectral efficiency by estimating the CSI with less measurement. However CS requires high computational cost that makes the method difficult for actual implementation. This paper proposes a new approach for channel estimation using reduced size sparse measurement matrix combined with Modified Orthogonal Matching Pursuit (MOMP) algorithm. The simulation shows that the proposed method provides less execution time for CSI calculation.

Authors: SHAH , M. I

Abstract: Requirements are at the core of all project deliverables. Ensuring that all project requirements are achieved by the project can be difficult to validate if no further means of tracing requirements is employed.Requirements traceability hence is a critical component of any project, as it provides the ability for a project to articulate how any given requirement has been met by the project deliverable. A great deal of research has been undertaken in this field, as requirements traceability although provides a very powerful and useful deliverable, is perceived as a very time consuming, cumbersome and labour intensive task. Due to this perception its popularity and usefulness can be compromised when short cuts are performed to minimise the time and effort that is devoted to documenting the traceability of the project requirements. This paper will look at the current state of play of requirements traceability.

Authors: HASLINIBINTI ABDULLAH , TAKEHIKO OGAWA

Abstract: Recently, the myoelectric potential generated by the movement of human muscle used as interface for controlling a robot arm and prosthetic device has been studied. The changes of myoelectric potential by muscle motion gave the impact of the robot arm control. It is proposed that electromyography (EMG) patterns can be analyzed and clarified by Neural Network (NN) for the motion determination. Thus, this paper proposes a pattern estimation method of forearm motion by Complex-Valued Neural Network (CVNN).The forearm motion was recorded by Surface Electromyography (SEMG) method as the analysis data from the area of the back and frontof the arm intermediate part. We focused on how to estimate between the four movements in this study using Complex-Valued Neural Network (CVNN). The results show how the methodology we adopted allows us to obtain good accuracy in estimating the forearm motion.

Authors: HIMADRI NATH SAHA , BIPASHA BANERJEE , DEBIKA BHATTACHARYYA , DEBOPAM GHOSH , ROHIT SINGH , SULAGNA MUKHERJEE

Abstract: Mobile Ad-hoc Network (MANET) is a wireless network model which is infrastructure-less and consists of mobile nodes. Since MANET does not have any centralized base station and is robust in nature, it is a major center of attraction. Due to the open nature, access to trusted authorities, the security in MANET poses a huge threat. Also energy constraint is another factor to be considered and thus, routing in MANET is a big challenge .In this paper we have discussed in depth about the various routing protocols in MANET and classify them. We have also discussed and compared their vulnerabilities in form of attacks, and classify these attacks. Brief descriptions of these attacks are given, mainly emphasizing on the network level attacks. Further we briefly review the existing secured MANET routing protocols to tackle these attacks and discuss their efficiency and shortcomings.

Authors: MINORU OKADA , TAKESHI HIGASHINO , SATOSHI TSUKAMOTO , TAKAHIRO MAEDA

Abstract: This paper proposes a new scheme of position location for radio terminals using MIMO-OFDM signal. First, this paper describes on a system configuration of LCX linear cell MIMO system and its research issues. Second, to observe channel responses depending on the terminal location, impulse responses are measured in the anechoic chamber. Third, principle of operation for positioning the radio terminals using multiple antennas and its signal processing using OFDM are described. The 2x2 spatial division multiplexing is successfully carried out using 2-port LCX as a transmitting antenna. Time difference of arrival (TDOA) is estimated at receiver by using its channel estimation function. From the experiments, the validity of averaging operation between estimated TDOAs are found to enhance positioning precision.

Authors: A. AL-TAIB AMER , AMER A. AMAR , M. JALBOUB

Abstract: In this paper, brief deals with a new initialization technique for digital IIR filters. The technique is suitable for IIR filters processing a finite number of samples in phased array radars. The initialization processor is complex one and utilized the first received sample to force the filter to reach its steady-state value at a single frequency irrespective of the number of processed samples. This is process is reached by initially loading the internal memories of the filter with their steady-state values. If the filter has a zero steady-state response at that particular frequency then this will ensure that the transient frequency responses of the filter will also have a zero response at that frequency. Different processors are derived for filters with real and complex coefficients.

Authors: AMER A. AMAR , M. JALBOUB , ABDALBASET M. IHBAL

Abstract: Over the next decades, the electricity system will face several chal-lenges originating from both supply and demand side. In the UK there is no real time retail market, and hence no real time retail electricitypricing. Therefore domestic electricity consumers in the UK pay electricity prices that do not vary from hour to hour, but are rather some kind of average price. Real time pricing information was identified as a barrier to understanding the effectiveness of various incentives and interventions. The key question is whether we can evaluate energy management, renewable energy and energy storage intervention in the behaviour of customers in real market terms. Currently only behaviour changes with respect to total consumption can be evaluated. Interventions cannot be defined for peak load behaviour. The effectiveness of the introductionof renewable energy is also hard to assess. Therefore, it is hard to justify introducing of energy storage and demand side management at local communit

Authors: AMER A. AMAR , ABDALBASET M. IHBAL , M. JALBOUB

Abstract: To meet an ever-increasing electrical load demand, modern power systems are undergoing numerous changes and becoming more complex from operation, control and stability maintenance standpoints. The major problem that is associated with such a stressed system is voltage instability or collapse. A system is said to enter a state of voltage instability when a disturbance causes a progressive and uncontrollable decline in voltage, which can occur because of the inability of the network to meet the increased demand for reactive power. Therefore, the voltage stability analysis is essential in order to identify the critical buses in a power system i.e., buses which are close to their voltage stability limits and thus enable certain measures to be taken by the operators in order to avoid any incidence of voltage collapse. Based on the basic understanding of voltage collapse and voltage stability analysis, a new index of analyzing static stability is proposed utilizing the power flow solution ba

Authors: MEENAKSHI SHARMA , NITISH KUMAR

Abstract: The promise of GIS has always been that it would allow us to obtain better answers to our Questions. But this is only possible if we have tools that allow us to perform rigorous quantitative analyses designed for spatial data. GIS provides us with a suite of analysis and modeling tools, ranging from small building blocks that you can use to construct a sophisticated work-flow, to completely self-contained analysis programs. It has a greater range of analysis and modeling tools, supports batch processing, offers new graphing functionality, automatically records work-flows for future reference, supports geodatabases, and can be called programmatically. It consists of algorithms that detect movement or changes in live and recorded video to see whether the movement or changes mean a possible threat is about to occur, occurring, or has occurred. One can also monitor video footage for missing or unwanted objects. Objects that have been left behind (bag containing a bomb) can be detected when

Authors: PUTRA SUMARI , SALEHAH HAMZAH

Abstract: Achieving fairness in peer to peer (P2P) file sharing require user’s contribution of bandwidth resource that is peer’s download bandwidth is equal to the upload bandwidth it contributes to the system. BitTorrent,a popular file sharing employs a “tit-for tat” (TFT) peer selection strategy to guarantee fairness, whereby a peer chooses to upload to a small set of neighboring peers that providing it with the best download rates. However, despite of BitTorrent achieves excellent utilization of upload capacity, many measurement and simulating studies found its fairness are less impressive where it lack of incentive for a peer to contribute and not effective enough to penalize free riders.This paper presents a literature survey of recent works of fairness improvement including free riders prevention in BitTorrent swarm through its TFT peer selection towards better downloading times and improve system stability.

Authors: ANTONI WIBOWO , FAUZIAH ABDUL RAHMAN , MOHAMMAD ISHAK DESA , NORHAIDAH ABU HARIS

Abstract: Data quality is a main issue in quality information management. Data quality problems occur anywhere in information systems. These problems are solved by data cleaning. Data cleaning (DC)is a process used to determine inaccurate, incomplete or unreasonable data and then improve the quality through correcting of detected errors and omissions. Generally data cleaning reduces errors and improves the data quality. It is well known that the process of correcting errors in data and eliminating bad records are time consuming and involve a tedious process but it cannot be ignored. Various process of DC have been discussed in the previous studies, but there’s no standard or formalized the DC process. Knowledge Discovery Database (KDD) is a tool that enables one to intelligently analyze and explore extensive data for effective decision making. The Cross-Industry Standard Process for Data Mining (CRISP-DM) is one of the KDD methodology often used for this purpose. This paper review and emphasize

Authors: NARENDRA S. CHAUDHARI , NEETESH SAXENA

Abstract: In this paper, we propose an improved and efficient AKA protocol named “NS-AKA” to prevent the 3G UMTS networks from various attacks like man-in-the-middle attack, redirection attack, replay attack and active attacks in the corrupted UMTS networks. This protocol completely eliminates the need of synchronization between a mobile station and its home network, and protects the actual identity of each user in the networks, (i.e., IMSI) by generating a temporary identity for each user during the authentication. The NS-AKA protocol generates minimum communication and computation overheads compared to UMTS-AKA, S-AKA, AP-AKA, and EURASIP-AKA protocols. On an average the NS-AKA protocol reduces 67% of the bandwidth consumption during the authentication process as compare to UMTS-AKA, which is the maximum reduction of bandwidth by any AKA protocol referred in the paper.

Authors: AYAT ALROSAN , NORITA NORWAWI , WALEED ALOMOUSH , WEDIAH ISMAIL

Abstract: Fuzzy clustering algorithms (FCM) have some disadvantage. The main disadvantage is the cluster centroids initialization sensitivity and trapped in local optima. This study proposed a novel clustering method by coupling artificial bee colony with fuzzy c-means (ABC-FCM) algorithm. The technique exploits the superior capabilities of ABC in searching for optimum initial cluster centers and uses these clusters as the input for FCM, thus improving the segmentation of MRI brain images. The performance of the newly developed approach was tested using two sets of MRI images: simulated brain data and real MRI images.
