Title:	A FUZZY APPROACH FOR REPRESENTATIVE NODE SELECTION IN CROSS LAYER TCP
Author:	A. CHANDRASEKAR, Dr. S. ARUMUGAM
Abstract:	A cross-layer based improved Transmission Control Protocol (TCP) protocol ensuring fair throughput and reliability was proposed in the previous investigations. In this protocol, data path was segmented, and representative nodes are maintained in every segment for any TCP connection. A Transmission Controller Module (TCM) is used by the representative node to determine bandwidth and delay in transmission and a Local Acknowledgement (LACK) message is sent to the source. Each LACK’s reception source calculates congestion window’s desired size, based on the forward path bandwidth, and Round Trip Time (RTT) values on forward path thereby avoiding congestion for larger extents, and increasing network data transmission rate. This study proposes to extend TCP. Representative nodes use fuzzy logic concept, dynamically. A node becomes a representative node when its two hop neighbours have poor link quality, high mobility and reduced bandwidth. The fuzzy rule generated in this study ensures increased throughput and reduced delay compared to conventional TCP.

Author:	S.MEENATCHI , C.NAVANEETHAN ,N.SIVAKUMAR , P.THANAPAL , J.PRABHU
Abstract:	Secure data transfer in Wireless Sensor Networks (WSN) is a challenge, as there are always chances for intruders to form a clone node to interrupt data packets. The proposed system Security in Wireless Sensor Networks by Broadcasting Location Claims (SWBC) engages with Area Based Clustering Detection (ABCD).ABCD divides the WSN into sub areas by implementing division of angle equally and nodes in the sub area elects a Witness node by using maximum neighbour nodes approach. Witness nodes are selected near to the central node to the transmission within the range. Witness nodes gets the location claims of the source node and central node manages the witness nodes where both central node and witness node identifies the intruder by broadcasting the location claims to all the nodes. By simulation SWBC gives the best security compared to the existing techniques like RED, and LSM. Simulation results enhance lifespan of WSNs, decreases the data traffic, detection of intruder before replication of data packets.

Title:	EFFICIENT REMOVAL OF IMPULSE NOISE FROM VIDEO USING ADAPTIVE THRESHOLD ALGORITHM
Author:	P. LATHA, Dr. M. A. BHAGYAVENI, S. R. PREETHI
Abstract:	In digital image processing noise removal or noise filtering plays an important role, because for meaningful and useful processing images should not be corrupted by noises. In recent years, high quality televisions have become very popular but noise often affects TV broadcasts. Impulse noise corrupts the video during transmission and acquisition of signals. A number of denoising techniques have been introduced to remove impulse noise from images and video. Linear noise filtering technique does not work well when the noise is non-adaptive in nature and hence a number of non-linear filtering technique where introduced. In non-linear filtering technique, median filters and its modifications where used to remove noise but it resulted in blurring of images. Therefore we propose an adaptive digital signal processing approach that can efficiently remove impulse noise from color video. In this algorithm, the pixel is replaced only if it is identified to be a noisy pixel by the proposed adaptive threshold algorithm otherwise the original pixel is retained. Thus it results a better filtering technique when compared to median filters and its modified filters. It is proved that the proposed algorithm is more suitable for high noise environment. The parameters Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) are measured for determining the visibility and similarity of output video frames.

Author:	ALI EL ALAMI , SAAD DOSSE BENNANI , MOULHIME EL BEKKALI , ALI BENBASSOU
Abstract:	In this paper, we propose a new structure patch antenna excited by two identical microstrip lines having a common feeding adapted to 50 ohm and intended to applications of Radio Frequency Identification (RFID). The slots inserted at the patch antenna have a direct impact on improving the radiation characteristics in terms of reflection coefficient, voltage standing wave ratio, input impedance and directivity over a range of frequencies ranging from 2 GHz up to 2.9 GHz. The analysis and optimization have been performed using the simulator HFSS (High Frequency Structure Simulator) based on the finite element method. Next, in order to validate our simulation, we use another electromagnetic simulator CST MWS (Computer Simulation Technology- MicroWaves Studio) which is based on the finite integration method. The simulation results of the two simulators agree well practically.

Title:	HONEYBEE PROTECTION SYSTEM FOR DETECTING AND PREVENTING NETWORK ATTACKS
Author:	AMAN JANTAN, ABDULGHANI ALI AHMED
Abstract:	An effective system inspired from honeybees protection mechanism in nature is proposed to detect and prevent network attacks. The proposed approach consists of multi-agents deployed in distributed locations in the network to discriminate normal from malicious activates. These agents recognize a network attack using a mechanism contains Undesirable-Absent (UA) or Desirable-Present (DP) methods. The mechanism of recognizing the attacks is achieved through monitoring, detection and decision stages of protection. The UA method is used in the monitoring stage for matching the normal behaviour based on absence of attacks’ signatures. The DP method is used in the detection stage for matching the malicious behaviours based on existence of attacks’ signatures. The detected attack is reported for prevention in the decision stage. Neural network which trained by Back Propagation algorithm (BP) is used to learn the patterns of network attacks. The performance of the proposed honeybee system is evaluated using KDD’99 dataset. The obtained results show that the protection mechanism is deployable and capable to detect various types of attacks while maintaining a low rate of false alarms.

Author:	T.KARTHIKEYAN, S.SUJATHA
Abstract:	The research work in this paper proposed and evaluated a dynamic unified model for Road Networks using various developed agents. An LTCDM (Linear Traffic Control Dynamic Model) is a multivariate dynamic model which uses a graph in which the vehicles are represented as nodes considering time series of flows at the various data collection site and uses finite capacity queuing theory. This dynamic and integrated model constructs real time decision making based on the host architecture and road network loads. The proposed model make use of Congestion Aware Multi Agent Path- planning (CAMAP) Algorithm to achieve social optimum by minimizing aggregate functioning time of all the agents to handle congestion effectively in this model. The aim of the research focuses on the development of LTCDM for road networks by integrating various mobile agents for handling traffic in road networks dealing with travel time uncertainty, congestion detection, severity, prioritization of emergency vehicles and finding best alternative path to avoid congestion. The proposed model also enhances the better quality of service for road networks by improving safety applications, finding best route and drivers comfort. The experimental study described in this paper has been carried out by NS2, SUMO and MOVE .By simulation results, it has been proved that the proposed integrated dynamic and unified model LTCDM attain high throughput and scalability compared with the existing models on road networks.

Title:	EFFICIENT ENERGY BASED CONGESTION CONTROL SCHEME FOR MOBILE AD HOC NETWORKS
Author:	S.SHEEJA, DR.RAMACHANDRA V PUJERI
Abstract:	In recent years, MANET is the popular and growing network used in various applications. Here the mobile nodes are randomly moving without any access point. Due to mobility of nodes, energy consumption of the network goes higher. More energy consumption occurs due to retransmission of packets and occurrence of packet loss unlimitedly. So the main goal of the network is to ensure more energy efficiency. To provide minimum energy consumption and avoiding more congestion, energy consumption model and multipath routing scheme is needed in networks. In this research paper, we developed an Efficient Energy based Congestion Control Scheme (EECCS) for congestion avoidance and to improve energy efficiency of the mobile nodes. Here the cross layer design is deployed to improve the network performance. The multipath routing is focussed to avoid congestion and to increase network lifetime. We also demonstrated the energy consumption mathematical model to illustrate the node’s minimum energy consumption level in the network. Probability of the retransmission of packets is reduced with the help of calculating the energy level of data and acknowledgment packets. By using extensive simulation, the proposed scheme achieves minimum energy consumption, low packet loss ratio, high packet delivery ratio, low end to end delay and overhead than our previous schemes like ECAS, CLSMRSCA.

Title:	LATENCY AND ENERGY AWARE BACKBONE ROUTING PROTOCOL FOR MANET
Author:	P.FRANCIS ANTONY SELVI, M.S.K.MANIKANDAN
Abstract:	Earlier woks on latency reduction in mobile ad hoc network (MANET) routing, lead to huge energy consumption due to the heavy load on each mobile node. There is a trade-off between energy reduction and latency reduction. Moreover, existing latency reduction techniques rarely consider retransmission latency, queuing latency and MAC layer latency apart from routing latency. In this paper, we propose to design a latency and energy aware backbone routing protocol for MANET. In the proposed protocol, backbone nodes collect the information of Residual Energy, Delay, MAC contention and Load from the nodes using neighbor monitoring mechanism. The collected information is stored in the Local Topology table from which the best routing paths are selected using the backbones.

Title:	VLSI IMPLEMENTATION OF KEY DEPENDENT SUBSTITUTION BOX USING ERROR CONTROL ALGORITHM FOR SUBSTITUTION-PERMUTATION SUPPORTED CRYPTOGRAPHY
Author:	B. SENTHILKUMAR, V. RAJAMANI
Abstract:	This paper describes about novel VLSI implementation of key based substitution box(S-box) for Substitution-Permutation supported private key cryptosystems. Our design uses the mathematical properties of the (8, 4) Extended Hamming Code and its error control logic to produce 256 unique elements in one S-box over finite Galois Field (GF) (28). Row – Column Index based selection of four 8bit vectors and their modulo-2 addition is employed for both byte substitution and its inverse. Proposed substitution method provides optimal substitution output probability with 40320 S-boxes for a single message byte over GF (28). Proposed method removes the direct relationship between linear and algebraic expressions of S-box vectors and byte substitution technique of S-box for strengthening our structure against linear and differential attacks. High nonlinearity penetration of original input message bits is achieved by applying shift based key schedules for round transformations and bit permutation based S-box vectors in proposed byte substitution. Proposed design is simulated and synthesized using VHDL coding for Spartan3E FPGA (XC3S500E-PQG208) and the simulation results are shown. Various substitution output results are shown by proposed S-boxes simulation for its optimal application. This paper concludes that novel Key dependent Substitution Box using Error Control Algorithm is an alternative solution to the existing threats on cryptography algorithms.

Title:	A NOVEL HYBRID AUTHENTICATION METHOD BASED ON ORIENTATION MAPS AND SERVER AIDED SIGNATURE FOR M COMMERCE SECURED TRANSACTIONS
Author:	R.ARUN PRAKASH, K.M.MEHATA, C.CHELLAPPAN
Abstract:	Mobile commerce (m-commerce) refers to the ability to perform wireless commerce transactions using mobile applications in mobile devices. It is an innovative concept and is emerging in a context of an established norms, regulations and standards. This paper presents a study of adoption determinants for mobile commerce, focusing on end-users of a mobile commerce pre-paid service. The main objective of the study is twofold; to determine an algorithm that improves security and decreases the time delay for processing of an adoption model by applying it to the results of the study. In order to investigate the field of mobile commerce service adoption, information related to its’ end-users was gathered. The framework was applied to the results of the study in order to validate its concepts. We proposed a model based biometric identification with SAS algorithm to obtain digital signature over the conventional method of merely algorithms to acquire signature. Biometric Identification Systems are widely used for unique identification of humans mainly for verification and identification. Biometrics is used as a form of identity access management and access control. Fingerprints are considered to be the best and fastest method for biometric identification. Hence we have adopted the finger print recognition for improving security. They are secure to use, unique for every person and do not change in one's lifetime. The findings of the case study indicate strong support for triangulating the three perspectives namely secured access, lesser processing delay and better signature generation method. The results of the same have been analysed and presented in this paper.

Title:	CUSTOM FUSION BASED ON BARYCENTER
Author:	ABDELBAKI ISSAM, BEN LAHMAR EL HABIB, LABRIJI ELHOUSSIN
Abstract:	Searching for information on the Internet is not only an activity newly rediscovered, but also a strategic tool to achieve a wide variety of information. Indeed, it’s extremely important to know how to find the information quickly and efficiently. Unfortunately, the Web is so huge and so little structured, that gathering precise, fair and useful information becomes an expensive task. In order to define an information retrieval tool (meta search engine) that brings together multiple sources of information search, interest must be credited to the merger phase of search engines results. On the other hand, information search systems tend primarily to model the user with a profile and then to integrate it into the information access chain, to better meet its specific needs. This paper presents a custom fusion method based on physical Barycenter method and values retrieved from the user profile. We evaluated our approach on multiple domains and we present some experimental results.

Abstract:	In close to future computing atmosphere, usually expected the recent progresses and advances in computing and communication technologies. Mobile Adhoc Network (MANET) is one of the promising fields for analysis and development of wireless network. Routing in wireless MANET has to be economical and saving of resources. One in every of the approaches to understand these items is completed by dividing the network into clusters and every cluster have a Cluster Head (CH) that’s answerable for the nodes associated among the cluster. Due to the dynamic atmosphere and random topology, the CH election technique has to be done per applicable criteria. This paper aims at weight based cluster routing with the improvement of QoS along with security. Here CH is chosen with relevance to weighted parameters like bandwidth, energy efficiency and link quality thereby giving higher QoS and elliptic curve digital signature algorithm which provides security from attacks by victimization Network Simulator-2. On scrutiny with CBRP protocol, this weight based cluster routing protocol achieves the QoS in economical and efficient manner.

Title:	A COMPARATIVE STUDY OF CLASSIFICATION MODELS FOR DETECTION IN IP NETWORKS INTRUSIONS
Author:	ABDELAZIZ ARAAR, RAMI BOUSLAMA
Abstract:	Intrusion detection is an essential mechanism to protect computer systems from many attacks. We presented a contribution to the network intrusion detection process using six most representative classification techniques: decision trees, BayesNet, NaïveBayes, Rules, SVM, and Perceptron multi-layer network. In this paper, we presented a feature selection using random forest technique, towards two dimensional dataset reductions that are efficient for the initial and on-going training. The well known KDD'99 Intrusion Detection Dataset is tremendously huge and has been reported by many researchers to have unjustified redundancy, this makes adaptive learning process very time consuming and possibly infeasible. 20 attributes are selected based on errors and time metrics. Performance and accuracy of the six techniques are presented and compared in this paper. Finally, improvement of supervised learning techniques is discussed for detecting new attacks. The different results and experiments performed using the principal component analysis and the enhanced supervised learning technique are thoroughly presented and discussed. We showed that J48 is the best classifier model for IDS with reduced number of features. Finally, avenues for future research are presented.

Title:	AN EFFECTIVE CROSS RATE PACKET AGGREGATION SCHEME FOR VIRTUALIZED NETWORK CLOUD COMPUTING
Author:	A. KAMALESWARI, P. THANGARAJ
Abstract:	Virtualization enables the cloud computing. The bottleneck of transferring packets from driver domain to Virtual Machines (VMs) in I/O channel was eliminated by Basic Aggregation and Destination based Aggregation scheme, but it is limited to aggregating packets for a particular destination and missing out more effective packet combinations. This can cause significant loss in capacity as packets on high quality links get demoted to low transmission rates. In this paper, using a new packet aggregation scheme, the network performance is improved. The proposed scheme aggregate the packet based on data rate dynamically on the I/O channel characteristic and it achieves better communication in cloud network, it balance the data rate between wired and wireless. The proposed model named as Cross Data Rate based Aggregation (CDRA) divides packet in MAC queue into groups based on the data rate, packets are to be transmitted at driver domain to VM. The algorithm aggregates packets in the same group and broadcasts the aggregated frame at the data rate of that group. CDRA aggregates packets for all links that have varying data rate and able to transmit packets out of order. The experimental evaluation shows that selectively demoting packets can further improve performance.

Title:	ZONE BASED RELATIVE DENSITY FEATURE EXTRACTION ALGORITHM FOR UNCONSTRAINED HANDWRITTEN NUMERAL RECOGNITION
Author:	K.N. SARAVANAN1, Dr. R. ANITHA
Abstract:	The recognition of handwritten characters and numerals has been a challenging problem among the researchers for few decades. This paper proposes a relative density feature extraction algorithm for recognizing unconstrained single connected handwritten numerals independent of the languages. The proposed method consists of four phases, namely, image enhancement (dilation), representation (zone based), feature extraction (relative density) and recognition (minimum distance classifier). The handwritten numerals must be enhanced with dilation, in order to connect the broken digits. After enhancement, the dilated binary images can be represented as a mid-point aspect ratio class interval values. There can be M * N zones and subsequently there would be 2M*N relational density exist using mid-point aspect ratio class interval values. In order to minimize the number of features, a subset of W relative densities has been extracted from the binary image since the relative density is too large to be handled efficiently. The minimum distance classifier technique has been used to recognize the given numerals. The proposed algorithm would be an alternative to recognize the handwritten numerals for recognizing unconstrained single connected handwritten numerals. The method sounds promising with a recognition rate of 92.8567%.

Author:	V.JAYALAKSHMI, DR.N.O.GUNASEKHAR
Abstract:	In this paper, Dynamic Voltage Restorer using Z source AC - AC converter has been proposed to mitigate the voltage sag/ swell. Dynamic Voltage Restorer (DVR) is an effective custom power devices used to protect the sensitive loads against voltage sag and swell. The three phase Z source AC-AC converter has been employed to perform the direct AC/AC conversion. The Z source network can produce any desired output AC voltage, which is a greater or less voltage than the line voltage. Hence it enhances the voltage restoration capability of DVR. The gating pulses for the bidirectional switch are generated using sinusoidal PWM technique and its associated circuitry. This proposed topology is simulated under voltage sag /swell using Matlab / Simulink and the simulation results are presented to show that the system effectively compensates the voltage sag/ swell.

Title:	A NOVEL COALITION GAME THEORY BASED RESOURCE ALLOCATION AND SELFISH ATTACK AVOIDANCE IN COGNITIVE RADIO AD-HOC NETWORKS
Author:	A.VELAYUDHAM, G.V.S GOHILA, B.HARIHARAN, M.M RAMYA SELVI
Abstract:	Cognitive radio (CR) is an intelligent radio, which is been targeted to exploit the utmost available spectrum holes for unlicensed users by sensing the environment. The arrival of advanced wireless communication devices lead to increase in the demand on the spectrum and the need to improve utilization of vacant spectrum. In the past decade the spectrum sensing and allocation has been the main focus of research rather than the security in cognitive radio. A selfish cognitive radio node is a serious security issue which occupies a part of the resources or full resource which is generally a pre-occupation problem in the multiple channel, and forbids other legitimate cognitive nodes from consuming the resources. This self-centered cognitive radio can critically degrade the performance of the network. So a skillful resource allocation strategy should be adopted to avoid these selfish attacks in the network. The conventional resource allocation approaches in the cognitive network are fully dependent. In this scheme, the coalitional game theory incorporates multiple PU and SU in a pool, in which the PU allow other SU’s to make use of its resources in contract or agreement on a timely basis. This scheme adopts efficient resource allocation in a multichannel cooperative system. This proposed system follows the core concept and also supports Shapley value in order to have a non-empty core in the network. The Shapley value equally distributes the payoff throughout the users in the network. It insists that the performance of the proposed scheme has been improved to a near optimum value of 93.7% rather than the performance of the existing COOPON system which figured to only about 74%. By this resource allocation approach, the selfish attacks can be prevented and thereby the efficiency of resource utilization in the network can be considerably increased.

Title:	DYNAMIC STRUCTURED PRIVILEGES WITH MULTI-OWNER DATA SHARING FOR DYNAMIC GROUPS IN THE CLOUD
Author:	A.VELAYUDHAM, M.M RAMYA SELVI, B.HARIHARAN, G.V.S GOHILA
Abstract:	Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet. The most basic and important service offered by cloud is data storage. However the major obstacle in the multi owner data sharing for the wide deployment of cloud computing is identity privacy while preserving data. In the existing approaches, a secure multiowner data sharing scheme, named Mona is used, for dynamic groups in the cloud that uses the group signature and dynamic broadcast encryption techniques. But this method to invoke and revoke of client is not dynamic on user privileges. Also the system supports only static groups. In the proposed scheme, we present an efficient structure for facts and figures sharing scheme to achieve dynamic privileges. Using this structure, any data owner can change the service class of each user dynamically and change the structure of privileges flexibly when it is needed. The proposed is also designed to support group migration between the users so that the users can revocate and change the group at any time. Thus by using the dynamic structure privileges, the system performs linearly with the increase in the number of users. But in the existing approaches, when the number of users increases the time execution is also increased which makes the system time consuming.

Title:	SURVEILLANCE OF VEHICLE OBJECTS WITH AERIAL IMAGES USING LOCALIZATION AND POSTURE BASED LOCAL GRADIENT MODEL
Author:	R.C.KARPAGALAKSHMI, DR.D.TENSING
Abstract:	Traffic scenes in road network needs to be monitored in different dimensional perspective to address the issues generated at various time instances. One of the major challenges observed in traffic scenes in road network is to address the vehicle tracking at different dimensional perspective for various time instances. One such application that has received greater significance is the mechanism to develop a full proof vehicle traffic control scheme. Videos fitted on different proposition of the signal junction able to view at respective image positioning and the overall traffic may rise to abnormality. Many studies have been examined for vehicle traffic control scheme. The recently used scheme is model based on simple object recognition and localization of road vehicles based on the position and orientation of vehicle image data. But the drawback of the approach is that if the shape of the vehicle and its pose varies in multiple junction coordination, the model based recognition is an inefficient one. To overcome the issues, in this work we are going to implement surveillance image object recognition and localization using improved local gradient model. The vehicle-object shape recognition and pose recovery in the traffic junction is carried out for varied traffic densities. An experimental evaluation is carried out to estimate the performance of the proposed Surveillance of Vehicle Object Recognition and Localization (SVORL) using improved gradient model in terms of vehicle density, traffic junction points, and computation time and compared with an existing model based on simple object recognition and localization.

Due to mobility of nodes, energy consumption of the network goes higher. More energy consumption occurs due to retransmission of packets and occurrence of packet loss unlimitedly. So the main goal of the network is to ensure more energy efficiency. To provide minimum energy consumption and avoiding more congestion, energy consumption model and multipath routing scheme is needed in networks. In this research paper, we developed an Efficient Energy based Congestion Control Scheme (EECCS) for congestion avoidance and to improve energy efficiency of the mobile nodes. Here the cross layer design is deployed to improve the network performance. The multipath routing is focussed to avoid congestion and to increase network lifetime. We also demonstrated the energy consumption mathematical model to illustrate the node’s minimum energy consumption level in the network. Probability of the retransmission of packets is reduced with the help of calculating the energy level of data and acknowledgment packets. By using extensive simulation, the proposed scheme achieves minimum energy consumption, low packet loss ratio, high packet delivery ratio, low end to end delay and overhead than our previous schemes like ECAS, CLSMRSCA.

Title:	A SURVEY OF RESEARCH AND PRACTICES IN MULTIPROCESSOR SYSTEM ON CHIP DESIGN SPACE EXPLORATION
Author:	V.PRASANNA SRINIVASAN, A.P.SHANTHI
Abstract:	This survey presents a perspective on the existing research and practices initiated for the Design Space Exploration (DSE) in Multiprocessor System on Chip (MPSoC) technology. Reduction in size as well as adding more functionality within a single chip by incorporating multiple processors remains the key in the development of the modern MPSoC. This rapid development has been made possible because of the techniques used for scaling down the size of the chip in the field of integrated circuits. MPSoC has been considered as the best candidate for applications such as networking, telecommunication, multimedia, etc. which require high computational demand, high performance, flexibility, high energy efficiency, and low cost design. The designers have the onerous task of building MPSoCs for such applications because they have huge design options in terms of Processing Elements (PEs), micro-architectural features, interconnects, etc. to be considered with specific constraints. Exhaustive search is prohibitive because of the sheer design space size as well as the time to market considerations. Coverage of design space during the exploration process, and evaluating a single design point for finding the optimal design are the two issues that should be considered in any DSE process. This paper provides a comprehensive survey on the existing DSE techniques at the system and micro-architectural levels, the evaluation methodologies and the tools/frameworks with their comparison with respect to the design parameters considered.

Title:	DESPECKLING AND SEGMENTATION OF ULTRASOUND IMAGES OF CAROTID ARTERY FOR PLAQUE DIAGNOSIS IN HEALTH CARE
Author:	D.SASIKALA, M.MADHESWARAN
Abstract:	A new method for segmentation of the carotid artery for classifying it as diseased or normal towards plaque diagnosis is proposed in this paper. Kernel Fuzzy C- Means clustering is used for segmenting the longitudinal section of the carotid artery using which the wall layers of the artery are identified for classifying it as diseased or normal. As a pre-processing step a–nonlinear mean filter is used for speckle filtering among a set of various traditional filters after measuring its performance. Removing speckle noise may remove useful information in the images like small lesions or artefacts, plaque or calcification in the arteries. Hence a filter that detects the speckle in each and every pixel and suppresses the speckled pixel is proposed in this paper. The algorithm was applied on ultrasound images of the carotid artery for extracting the boundary of the arterial wall and detecting the wall layers for clinical purposes. The results show excellent performance of the method.

Title:	BONE FRACTURE DETECTION USING OPENCV
Author:	SAMUEL FEBRIANTO KURNIAWAN, I KETUT GEDE DARMA PUTRA, A.A KOMPIANG OKA SUDANA
Abstract:	Image processing is important in modern data storage and data transmission especially in progressive transmission of images, video coding (teleconferencing), digital libraries, image database, and remote sensing. The purpose of this project is to find out the accuration of an X-Ray Bone Fracture Detection using Canny Edge Detection Method. Fractured bone is a bone condition that suffered a breakdown of bone integrity. A disconnected connection between two cartilages also categorized as bone fracture. Normally, bones have elasticity and a great number of strength. Bone fracture only happen when the bones took a force beyond their elasticity or strength. This system is built using OpenCV library combined with Canny Edge Detection method to detect the bone fracture. Canny Edge Detection method is an optimal edge detection algorithm on determining the end of a line with changeable threshold and less error rate. The simulation results have shown how canny edge detection can help determine location of fractures in x-ray images.

Title:	EVALUATION SUBQUERY METHODS IN MICROSOFT SQL SERVER 2008
Author:	TANTY OKTAVIA
Abstract:	Frequently user compiles a query to satisfy business process needs, whether directly using DBMS or connecting into application system. There are many methods that can be used to generate desired results to support transaction, but all the query processing should be run effectively and efficiently. A significant aspect of query processing is how to choose an efficient execution strategy to minimize resource usage. Based on competitive environment in industry, many companies compete with each other to be a number one. For this reason, company doing a lot of experiments, in order to accomplish a visions and mission objectives. One of those is increasing performance of the system to support daily activities. Nowadays, most of business process in company already integrated with information technology. All of data is consolidated by database, so user easily doing their job. According to this fact, user does not matter about how many transactions to be process per day, but how much time they need to process that transaction is the priority concern. Because of that, query optimization techniques become more important to be applied in many applications. In this research focused on measurement effectiveness of the method sub query which can be applied to reach optimal execution and present a comparative study of various cost to declare Sub query. This study based on Microsoft SQL Server 2008 platforms.

Title:	EDCA LIMITATION WITH HIGH TRAFFIC REAL TIME APPLICATIONS
Author:	AHMED ABU-KHADRAH, ZAHRILADHA ZAKARIA, MOHDAZLISHAH OTHMAN
Abstract:	The simplicity of expanding and maintenance wireless network helped to use it widely in the public locations such as parks, airports and bus stations. Distributed Coordination Function (DCF) and Enhanced Distributed Channel Access (EDCA) protocols are used with WLANs. DCF protocol sends its data without any priority between different data types, and does not give any advantage of real time application such as voice over internet protocol (VOIP) or video conference. However EDCA protocol divides data to different class’s voice, video, best effort and background. Each class has its own priority and parameters. The default values of EDCA protocol give voice traffic the highest priority. Quality of Service (QOS) parameters such as end to end delay, packet loss and jitter values determine if the protocol support QOS or otherwise. This paper evaluates the performance of DCF protocol and EDCA protocol by using OPNET simulation and shows the differences between them, depending on QOS parameter values. The result of simulation shows the limitation of EDCA protocol when increasing the number of VOIP users. Therefore the EDCA protocol tolerates specific number of real time applications with acceptable values of QOS parameters.

Title:	AN ECONOMIC APPROACH TO SPEED REGULATION OF INDUCTION MOTOR USING SUPER LIFT LUO CONVERTER
Author:	P.ELANGOVAN, Dr.C .KUMAR, B .GOMATHY
Abstract:	This paper proposes an economic approach for the speed control of Induction motor using positive output super lift Luo converter circuit. In the conventional method, the input of the inverter is derived from buck, boost or buck-boost converter which has the limitations over the DC link voltage level, complexity of control circuit and cost involved in system design. The proposed method uses positive output super lift Luo converter at the front end which boosts up the DC link voltage level in a wide range. The speed control of the induction motor is attained by controlling the firing angle of positive output super lift Luo converter instead of Inverter which leads to prevention of motor terminals from Common mode voltage stress. Super-lift Luo-converters are popular for high output voltage application over years. They have very high voltage transfer gains in geometric progression on stage-by-stage. The proposed system uses PI controller which is highly preferable for industrial applications. The simulation is conceded out by MATLAB/SIMULINK software.

Title:	IMPLEMENTATION OF NONDOMINATED SORTING GENETIC ALGORITHM – II (NSGA-II) FOR MULTIOBJECTIVE OPTIMIZATION PROBLEMS ON DISTRIBUTION OF INDONESIAN NAVY WARSHIP
Author:	HOZAIRI, KETUT BUDA A, MASROERI, M.ISA IRAWAN
Abstract:	The high number of crimes and infraction that occurred in the Indonesian seas show the weakness of Indonesia's marine security. This is caused by the limited number of warships of the Republic of Indonesia (KRI), the lack of budget provided by the State, the wide area of the marines in Indonesia that should be secured, and the less precise decision from the Navy in determining the safety operational management of Indonesian seas. Therefore, problems in securing Indonesian seas not only in the form of a single objective problem but has become a model of multi-objective problem. So there’s a way needed to solve this problem by using the best solution search using Nondominated Sorting Genetic Algorithms II (NSGA-II), this method is used because it can generate a better solution with less calculations, elitism approach, and a little more parameters division compared with simple NSGA. This study will determine the best combination of a 100 solution recommended by NSGA II in the focus of the type of the ship, speed, radar range, endurance, the area vulnerability level, geography, human resources, so it can be obtained one ideal solution in the focus of the placements composition of 27 warships to the 7 sectors in the ARMATIM area by maximizing the coverage area and minimizing the operational costs. The results of the optimization of NSGA-II with 100 iterations, it is resulted that 23 warships selected and 4 warships docking with a combination of warships in each sector (S1 = 2, S2 = 7 S3 = 6, S4 = 2, 3 = S5, S6 = 2, S7 = 1), the broader outcomes of the coverage area is 1, 722, 880 Mil2, so it can increase the security of territorial ARMATIM seas around 2% from the total secured area of 1,688,765 Mil2, and operational cost Rp. 4.521.548.485,- the optimization model is thus able to save about 10% of the State budget of the specified the budget of Rp. 5.000.000.000,-.

Title:	DEVELOPMENT OF A CONVERGENCE SCHEME FOR ONE-TO-MANY COOPERATIVE WIRELESS SYSTEMS USING A NON-COOPERATIVE GAME
Author:	OLUSEYE ADENIYI ADELEKE, MOHD FADZLI MOHD SALLEH
Abstract:	In this paper, we propose a new scheme for ascertaining convergence in cooperative wireless communications, using a new type of game called the Bidding game. Previous related works have all considered networks with many source nodes interacting with either single or multiple relay nodes, but because of the need to consider how partners are selected as well as how power is allocated, we propose this new game-based convergence scheme, in which the conventional theories of economic bidding are applied and optimization tools are employed. In this work, we model the cooperative communication network as a single-user, multi-relay node system in which the source node acts as the auctioneer while the relay nodes or partners act as the bidders in the game. The resource being auctioned here is power. The relay node which offers the highest bid in terms of price is first selected by the source node and then allocated power by the source node and then the convergence scheme ascertains how fast convergence to equilibrium is reached in the game. We also show that there exists bidding and pricing mechanisms or strategies that lead to the maximization of network throughput or utility in cooperative communication networks. Simulations are run to validate our proposed scheme.
