Title:	I/O MATCH (I/O MAT) AND BEHAVIORAL MATCH (BEH MAT) BASED SEMANTIC WEB SERVICE DISCOVERY
Author:	J.UMA MAHESWARI, Dr.G.R.KARPAGAM
Abstract:	Discovery is one of the central reasoning tasks in SOA systems, concerned with the detection of usable Web services for a specific request or application con-text. Aiming at the automation of this task, most existing works on semantically enabled Web service discovery focus on the degree of match of two services based merely on their I/O pairs. Another approach for matchmaking in Semantic Web Services (SWS) that considers each service as a sub-graph of the semantic network of the ontology formed by inputs, outputs, pre and post-conditions with contribution of syntactical information such as keywords and textual descriptions. The similarity between services is defined as the similarity between these graphs (Behavior Graphs). This paper presents the detailed description of both approaches and it also analyses the advantages, disadvantages and retrieval effectiveness of these two matchmaking systems (I/O Mat, BEH Mat) and proposes new algorithm for semantic match making.

Title:	HYBRID OPTIMIZED LIST SCHEDULING AND TRUST BASED RESOURCE SELECTION IN CLOUD COMPUTING
Author:	V.SURESH KUMAR, Dr. ARAMUDHAN
Abstract:	Cloud computing is computing service delivery over the Internet. Cloud services allow people and businesses to use software/hardware managed by third parties in remote locations. Cloud computing ensures access to information and computer resources from wherever a network connection is available. Task scheduling is fundamental to achieving cloud computing efficiency. But, it is a challenge to efficiently schedule algorithm design and implement it, as general scheduling is a NP-complete problem. Most task-scheduling cloud computing methods consider task resource requirements for CPU and memory, and not bandwidth requirements. This paper proposes to optimize scheduling using BAT-Gravitational hybrid algorithm with resources being chosen on trust.

Title:	RECONFIGURABLE AND MODULAR BASED SYNTHESIS OF CYCLIC DSP DATA FLOW GRAPHS
Author:	AWNI ITRADAT
Abstract:	The conventional high level synthesis techniques target DSP algorithms onto architectures using basic functional units such as adders or multipliers. In this paper, a scheme for the partitioning of the data flow graph of a DSP application for a high-level synthesis aimed at a design using multi-modules is proposed. In the propose scheme, the regularity characteristics of DSP application are exploited. Moreover, in order to reduce the number of distinct modules, the near-isomorphism sub-graphs represents the modules are merged together by multiplexing them in time to produce a single adaptable module. This merging process enables the reuse of the adaptable modules by partially reconfiguring them at run time to realize different modules during the running of the DSP data flow graph. Furthermore, a novel reconfigurable multiplier multiplier is incorporated in the proposed synthesis technique. It is seen that a small overhead in terms of the architecture’s controller is needed by the modules in order for them to be adapted to perform different computations (multi-modes).

Title:	CDMA BASED SECURE CROSS LAYER FRAMEWORK FOR AUTHENTICATION AND SCHEDULING IN MANET
Author:	B.BERIL DANIEL ROSARIO, Dr.A.RAJARAM
Abstract:	In MANET, mobile nodes are connected without any centralized administration. Due to that, a mobile node is easily affected by means of several attacks. Due to these attacks, network is totally partitioned and more packet congestion occurs. Because of improper scheduling, congestion level of network will get increase unlimitedly. To provide an authenticity of data packets and avoiding more congestion, there is a need of secure and scheduling mechanism in networks. In this research paper, we developed a CDMA based Secure Cross layer framework for authentication and scheduling. Here the cross layer is introduced to improve the quality and lifetime of nodes as well as links. The scheduling procedure is proposed to reach the packets in a time slot manner. In authentication phase, we proposed the modified concept of RSA scheme. Here the asymmetric key is chosen. Both encryption and decryption phases are used to validate the cipher text and manipulate the plaintext according the given message. By using extensive simulation, the proposed scheme achieves better throughput, packet delivery ratio, low end to end delay and overhead than the existing schemes.

Title:	AN EFFICIENT TRACE ORIENT CLUSTER HEAD SELECTION FOR ADAPTIVE CLUSTER BASED ROUTING IN MANET’S
Author:	A. BAJULUNISHA, J.WILLIAMS
Abstract:	To minimize the overheads of routing and to reduce energy loss on mobile nodes, various routing strategies has been adapted in literature for Manet. Most of the methods, suffers with cluster head selection problem and which generates energy holes in the co-operative routing. To overcome the problem of energy holes and cluster head selection, we propose a trace oriented approach for cluster head selection problem which selects based on various parameters like movement trace, mobility speed, and earlier transmissions. We also focus on the selection of co-operative nodes, where the energy efficiency has to meet to overcome the energy holes in the boundary. For given cluster Ci, the selection of cluster head CH is performed based on node weight which is computed using above said parameters and a set of co-operative nodes Co is selected according to boundary closure measure and energy constraints. The proposed approach has minimized the overhead of cluster head selection by Nlog102 and overall throughput has been increased.

Title:	USER INTERACTIVE MULTI-VARIANT FEATURE GRAPH BASED ENERGY ESTIMATION TECHNIQUE FOR IMAGE SEGMENTATION
Author:	S. SASIKANTH, Dr. S. SURESH KUMAR
Abstract:	Image segmentation techniques are discussed earlier which uses color, intensity, pixel values and etc, and suffers with the problem of overlapping and grouping efficiency. We propose a novel method for image segmentation, using multi variant feature based energy estimation technique and works with interactive mode. Unlike other methods, the proposed methodology computes the feature energy of each pixel. The Feature energy represents the propagation of feature from one pixel to another and energy transition occurred at each of the neighbor pixel. The energy estimation is performed using various features of each pixel and its neighbors. An each pixel becomes the member of a group only if it carries same set of energy level or same set of features with possible little changes and comes within the energy threshold. The features used to compute the energy level are pixel values like red, green, blue and the number of neighbors and their values. The computed value is used to perform segmentation process, and produces higher rate of segmentation. The process will be performed iteratively still the user gets satisfied and provides new energy threshold value.

Author:	GARIMELLA UMA PAPA, Dr. S. BASKAR Dr.K. RAJAN
Abstract:	This paper is a study on the design of fuzzy logic controller plus proportional integral (FLC plus PI controller) based load frequency control (LFC) for hybrid generator network (HGN), which is the combination of the diesel generator and the solar PV panels. The different variations are considered as a step to the solar PV panels. The transfer function models of the HGN and the PV are simulated at first and then they can be linked with each other through Tie-Line. Next, in order to control the created disturbance of the network, a FLC plus PI controller is developed. The performance of complete model with FLC plus PI controller is verified at transient region through the computer simulation with help of the MATLAB/Simulink software platform. In comparison with the PI controller and the FLC, the simulation results are clearly evident that the designed controller is proficient over the PI controller and the FLC.

Title:	NEW SOLAR-CELL COATING TO ENABLE BOOST IN EFFICIENCY
Author:	J.MANJU, DR.S.JOSEPHJAWHAR
Abstract:	These days Solar Energy is discriminatingly required to satisfy the human needs. Anyway amid the energy conversion [sunlight into Current] the measure of transformation is not sufficient and it is less because of sun powered shaft reflection on the surface of the solar panel.This strategy never surpasses 34% for a solitary advanced semiconductor intersection. The current framework utilized aqueous strategy, and the nanoparticles arranged are Zn + Mg co-doped TiO2 and the immaculate TiO2 and the transformation proficiency arrive at up to 9.07%. The main objective of this paper is to improve the energy conversion rate in terms of reducing the Reflection. In the past studies in photovoltaic [PV] cell, if one proton thumps then one electron detached in the PV material. In this paper another system is presented where in a PV cell, every photon can rather thump two electrons detached by changing the semiconductor as 'n-type- semiconductor' and which gets to be Group-V components. This makes the process significantly more productive than the current methodologies. In a standard cell, any overabundance energy conveyed by a photon is squandered as high temperature, although in the new framework the additional energy goes into handling two electrons rather than one. The resultant current is very nearly straightforwardly corresponding to the force of the light.

Title:	DESIGN OF OPTIMUM PID CONTROLLER FOR NONLINEAR PROCESS USING EVOLUTIONARY ALGORITHMS
Author:	VIJAYAKUMAR KALIAPPAN, MANIGANDAN THATHAN
Abstract:	In past decades, PID controller was mostly preferred because of its robust behavior in a spread over range of operating conditions. However the conventional PID tuning procedure is not suitable for getting the optimized controller parameters under the identified operating regions. Therefore, an optimum Particle Swarm Optimization (PSO) based Proportional-Integral-Derivative (PID) controller is proposed for controlling the nonlinear process with optimized PID parameters settings. The PSO computation technique has many advantages like high quality solution, less computation time and good convergence characteristics. The tuning of PID parameters through optimization algorithms provides high quality solution for nonlinear processes. The performance indices such as ISE, IAE and ITSE were studied to evaluate the proposed controller performances. The proposed PID controller is presented to a nonlinear Continuous Stirrer Tank Reactor (CSTR) process for controlling the concentration by manipulating its feed flow rate. From the results, it is observed that the PSO-PID provides better control accuracy than other methods such as Simulated Annealing (SA) and Genetic Algorithm (GA) based controllers.

Title:	MODELING AND SIMULATION OF CNTFET FOR PROSTATE CANCER DETECTION
Author:	B.N. SHOBHA, N.J.R. MUNIRAJ
Abstract:	Prostate cancer is the major cancer affecting men and is growing at a very significant rate. One of the major challenges in treatment of prostate cancer is its detection in early stages. The use of Prostate Specific Antigen (PSA) testing has aided the prediction of prostate cancer. It is important to develop an ultrasensitive and selective biological sensor for PSA detection. An ultrasensitive biological detection system that allows the early detection of prostate cancer is expected to improve preventative healthcare. The most widespread techniques for detecting prostate cancer are based on the enzyme-linked immunosorbent assay (ELISA). Recently, biomolecule sensors based on quasi one-dimensional semiconductor nanostructures like nanotubes, nanowires and nanobelts have attracted considerable attention because of their distinct electrical, optical and magnetic properties. Hence, this paper analyzes the device properties of Carbon Nano Tubes (CNT) such as mechanical properties, optical and electrical properties and its relevance as prostate cancer detector or PSA detector. The comparison of MOSFET inverter with CNTFET is also carried out and found that CNTFET has same performance as that of MOSFET with less complexity.

Title:	THE NEW APPROACH OF VISUAL CRYPTOGRAPHY SCHEME FOR PROTECTING THE GRAYSCALE MEDICAL IMAGES
Author:	S.MANIMUURGAN, C.NARMATHA, K.PORKUMARAN
Abstract:	Transferring an image from one place to another or storing an image in a particular place in a secure manner has become a challenge. In order to face this challenge, a new Visual Cryptography (VC) scheme for grayscale medical images has been proposed. Generally, the VC method has a few problems or rather, short comings. For instance, when the pixels are expanded, the level of security applied will be high but the quality of reconstructed image will be low. Similarly, if the extent of pixel expansion is reduced, its security is lowered and quality of the image is retain. Hence, to achieve high security as well as to get a good image quality, the proposed Tailored Visual Cryptography Scheme (TVCS) for grayscale medical image is ideal. Some of the VC leads to loss while reconstructing the image but this proposed algorithm which has been developed for medical image, will not provide any loss and the result has been experimented and proved by measuring CC. The main advantage of this proposed method is to provide good quality for the images with reliable security without any pre or post processing. In the proposed algorithm, two types of processes are taking place: Tailored Visual Cryptography Encryption (TVCE) and Tailored Visual Cryptography Decryption (TVCD). The TVCE process provides an encrypted image and in order to get this encrypted image, Splitting Process, Converting Process, Pixel Process and Merging Process are performed. Simultaneously Segregation Process, Inverse Pixel Process, 8-bit into Decimal Conversion Process and Amalgamate Process are involved to retrieve the original medical image from the TVCD process. In the experimental part, many medical images have been tested and the result is also provided. In order to check the security properties like Confidentiality, Integrity and Availability (CIA), the CC has been calculated. From these experimentations, the proposed algorithm provides better result than the existing algorithms.

Title:	RANDOMNESS TEST OF CRYPTOGRAPHIC ONE-TO-MANY REVERSIBLE MAPPING FOR IPV6 ADDRESS GENERATION
Author:	NASHRUL HAKIEM, MOHAMMAD UMAR SIDDIQI, SIGIT PUSPITO W. JAROT, AKHMAD UNGGUL PRIANTORO
Abstract:	This paper presents simulation results on randomness test of a cryptographic one-to-many reversible mapping between user space and the IPv6 address space. A one-to-many reversible mapping mechanism is developed which may be embedded into a DHCPv6 (Dynamic Host Configuration Protocol for IPv6) server in the stateful mode within an enterprise local area network (LAN). Each time a user accesses the network, the DHCPv6 server is able to assign a dynamic IPv6 address. The dynamic address (obtained through one-to-many mapping) is to protect the user from unwanted behavior analysis exploiting IPv6 addresses, thus protecting user privacy. However, the dynamic address can be uniquely linked to the user (through many-to-one reversible mapping) if the need arises. The randomness of the dynamic address (one-to-many mapping) for IPv6 address assignment is evaluated based on uniformity using monobit (frequency) test, and avalanche effect is evaluated using Hamming distance tests. Simulation results show that the randomness in terms of uniformity (occurrence of 1's or 0's are around 50%) and the Hamming distance (the difference between Interface IDs at approximately 50%) are accepted. The decision rule of randomness is set at the 1% significance level with the Pvalue of monobit (frequency) test, and the Pvalue in Hamming distance tests is taken to be more than 0.01. IPv6 addresses generated by a one-to-many reversible mapping mechanism are considered to be random with a confidence level of 99%.

Title:	FREQUENCY BASED AUDIO FEATURE EXTRACTION FOR RAGA BASED MUSICAL INFORMATION RETRIEVAL USING LPC AND LSI
Author:	Ms.P.KIRTHIKA , Dr. RAJAN CHATTAMVELLI
Abstract:	This paper introduces the Audio Feature Extraction for classifying the music based on Raga which plays a major role in Music Information Retrieval (MIR) systems. The backbone Indian Classical Music is its Raga. A Raga is a particular blend of notes which follows specific laws. The existing MIR systems and audio search engines concentrate on content based audio mining and also the searches are made by Meta Data which needs human effort for tagging. The existing MIR systems also do not concentrate on Ragas . In this paper, we propose how the frequency can be used to determine a raga by using Linear Predictive Coding(LPC). We also propose a method to identify the Raga of the input audio clip using Latent Semantic Indexing(LSI).

Title:	HARDWARE-SOFTWARE SYSTEM FOR MALICIOUS LOGIC DETECTION IN HARDWARE INFRASTRUCTURE OF CARS
Author:	NIKOLAY KALINTSEV, DMITRY MIKHAYLOV
Abstract:	Electronics control almost all vehicle systems. Such systems have a serious vulnerability problem at the hardware level and can be subjected to unauthorised actions by an attacker. This paper deals with the issue of security of car infrastructure. The article gives the basic information about Controller Area Network bus system, describes security problems of embedded automotive systems and the “bug” capable of intercepting driving that was developed as an example of the hardware attacks described in the paper. To solve the problems caused by the bug the special hardware-software complex was designed to detect the bug in the onboard vehicle system that can be insert for example during tech inspection. There are two main options for detecting and protecting against unauthorised connection: monitoring of resistive and capacitive condition of buses and blocking commands, which introduce one or more blocks in the service mode. The article presents an algorithm of this defence mechanism. The effectiveness of the proposed hardware-software complex was proved experimentally.

Title:	DATA CLUSTERING BASED ON HYBRID OF FUZZY AND SWARM INTELLIGENCE ALGORITHM USING EUCLIDEAN AND NON-EUCLIDEAN DISTANCE METRICS: A COMPARATIVE STUDY
Author:	O.A. MOHAMED JAFAR, R.SIVAKUMAR
Abstract:	Data mining is a collection of techniques used to extract useful information from large data bases. Data clustering is a popular data mining technique. It is the task of grouping a set of objects into classes such that similar objects are placed in the same cluster while dissimilar objects are in separate clusters. Fuzzy c-means (FCM) is one of the most popular clustering algorithms. However, it has some limitations such as sensitivity to initialization and getting struck at local optimal values. Swarm intelligence algorithms are global optimization techniques and are recently successfully applied to solve many real-world optimization problems. Constriction Factor Particle Swarm Optimization (cfPSO) algorithm is a population based global optimization technique which is used to solve data clustering problems. Euclidean distance is a well known and commonly used metric in most of the literature. Some drawbacks of this distance metric include blind to correlated variables, not robust in noisy environment, affected by outlier data points and handle data sets with only equal size, density and spherical shapes. But real-world data sets may exhibit different shapes. In this paper, a Fuzzy based Constriction Factor PSO (FUZZY-cfPSO-FCM) algorithm is proposed using Non-Euclidean distance metrics such as Kernel, Mahalanobis and New distance on several benchmark UCI machine learning repository data sets. The proposed hybrid algorithm makes use of the advantages of FCM and cfPSO algorithms. The clustering results are also evaluated through fitness value, accuracy rate and failure rate. Experimental results show that proposed hybrid algorithm achieves better result on various data sets.

Title:	AN EFFICIENT DELAY AWARE ROUTING PROTOCOL FOR REAL TIME SYSTEMS IN WIRELESS SENSOR NETWORK
Author:	GHUFRAN ULLAH, ABDUL HANAN ABDULLAH, ROHANA YUSOF
Abstract:	Many of Applications have got much attraction of Wireless Sensor Networks (WSNs) due to its multi features with low cost and are getting more and more advancements. Usually in WSN, nodes are deployed in a region to sense the events and send the sensed data towards the sink(s) or a base station through single/multi-hop communications. However, real time systems have its specific QoS requirements which are different from usual WSN applications as the data packets must be delivered in time deadline. In this study we propose an efficient delay aware routing protocol (EDARP) in order to enhance the QoS parameters and to satisfy the end to end delay and reliability requirements of real time WSNs applications. Delay-aware routing protocol (DARP) sustains a continuous speed of data delivery to provide the best communication in real-time. The proposed protocol is compared with state of art protocols for different simulation scenarios and the results show that EADRP has got better performance in terms of end to end delay and reliability.

Title:	E-READINESS: A NOVEL APPROACH FOR INDICATORS MEASUREMENTS ESTIMATION AND PREDICTION
Author:	NAJIB BELKHAYAT ZOUKKARI, ABDELAZIZ DOUKKALI, BOUBKER REGRAGUI
Abstract:	E-Readiness is an assessment process for the ICT (Information and Communication Technologies) availability and use in a country. It consists in the calculation of a composite indicator based on a conceptual framework related to ICT aspects. The assessment report is used in E-Strategy to formulate action plans for e-Readiness index development. Several approaches are used for e-Readiness since the end of nineties; these approaches lack flexibility and require frequent and precise measurements. Thus, two issues are addressed in this paper: the missing measurements estimation problem and the lack of e-Strategy formulation assistance and simulation tools and approaches. Indeed, we propose in this paper an approach to define the transition matrix of the e-Readiness state equation based on a layered model. This construction leads to a state model related to the e-Readiness dynamic system and then is used with KALMAN Filter to cover the two addressed issues. Indeed, the commands variables are indicators that can be manipulated by e-Strategy stakeholder and the KALMAN filter estimation and prediction functions are used as a simulator. For validation, we constructed a model based on the I2010 e-Readiness initiative and we tested the convergence of the model and its prediction function. Results are encouraging since the tested model prediction function converges in 24 cases out of 27 (89%).
