Abstract— The main objective of this paper is to design and develop the Self-Adaptive Media Service Architecture (SAMSA) for providing reliable multimedia services through policy-based actions. The distributed multimedia services deployed using SOA can be accessed in heterogeneous environments that are prone to changes during run-time. To provide reliable multimedia services, a powerful self-adaptable architecture is necessary to adapt at run time and react to the environment. The adaptability in this proposed architecture is achieved by enabling the service providers to Monitor, Analyze and Act on the defined policies that support customization of compositions of multimedia services. The Media Service Monitor (MSM) observes the business and quality metrics associated with the media services at run-time. The Adaptive Media Service Manager (AMSM) takes corrective actions based on the monitored results, through the policies defined as an extension of WS-Policy. The effectiveness of the proposed SAMSA has been evaluated on Dynamic Composite Real-Time Video on Demand Web Service (DCRVWS) for a maximum of 200 simultaneous client’s requests. The analysis of results shows that the proposed architecture provides 20% improvement on reliability, response time and user satisfaction.

Index Terms— DCRVWS, Media Service Monitor, Reliable Multimedia Service, SAMSA.

Abstract— Automatic marker-less 3D human body modeling for the motion analysis in security systems has been an active research field in computer vision. This research work attempts to develop an approach for 3D human body modeling using thinning algorithm in monocular indoor video sequences for the activity analysis. Here, the thinning algorithm has been used to extract the skeleton of the human body for the pre-defined poses. This approach includes 13 feature points such as Head, Neck, Left shoulder, Right shoulder, Left hand elbow, Right hand elbow, Abdomen, Left hand, Right hand, Left knee, Right knee, Left leg and Right leg in the upper body as well as in the lower body. Here, eleven activities have been analyzed for different videos and persons who are wearing half sleeve and full sleeve shirts. We evaluate the time utilization and efficiency of our proposed algorithm. Experimental results validate both the likelihood and the effectiveness of the proposed method for the analysis of human activities.

Keywords- Video surveillance, Background subtraction, Human body modeling, Thinning algorithm, Activity analysis.

Abstract— This paper presents a new methodology for discovering features of texture images. Orthonormal Polynomial based Transform is used to extract the features from the images. Using orthonormal polynomial basis function polynomial operators with different sizes are generated. These operators are applied over the images to capture the texture features. The training images are segmented with fixed size blocks and features are extracted from it. The operators are applied over the block and their inner product yields the transform coefficients. These set of transform coefficients form a feature set of a particular texture class. Using clustering technique, a codebook is generated for each class. Then significant class representative vectors are calculated which characterizes the textures. Once the orthonormal basis function of particular size is found, the operators can be realized with few matrix operations and hence the approach is computationally simple. Euclidean Distance measure is used in the classification phase. The transform coefficients have rotation invariant capability. In the training phase the classifier is trained with samples with one particular angle of image and tested with samples at different angles. Texture images are collected from Brodatz album. Experimental results prove that the proposed approach provides good discrimination between the textures.

Abstract—The incomplete data is an important problem in data mining. The consequent downstream analysis becomes less effective. Most algorithms for statistical data analysis need a complete set of data. Microarray data usually consists of a small number of samples with high dimensions but with a number of missing values. Many missing value imputation methods have been developed for microarray data, but only a few studies have investigated the relationship between missing value imputation method and classification accuracy. In this paper we carry out experiments with Colon Cancer dataset to evaluate the effectiveness of the four methods dealing with missing values imputations: the Row average method, KNN imputation, KNNFS imputation and Multiple Linear Regression imputation procedure. The considered classifier is the Support Vector Machine (SVM).

Keywords; KNN, Regression, Microarray, Imputation, Missing Values

Abstract— Optimal inventory control is one of the significant tasks in supply chain management. The optimal inventory control methodologies intend to reduce the supply chain (SC) cost by controlling the inventory in an effective manner, such that, the SC members will not be affected by surplus as well as shortage of inventory. In this paper, we propose an efficient approach that effectively utilizes the data mining concepts as well as genetic algorithm for optimal inventory control. The proposed approach consists of two major functions, mining association rules for inventory and selecting SC cost-impact rules. Firstly, the association rules are mined from EMA-based inventory data, which is determined from the original historical data. Apriori, a classic data mining algorithm is utilized for mining association rules from EMA-based inventory data. Secondly, with the aid of genetic algorithm, SC cost-impact rules are selected for every SC member. The obtained SC cost-impact rules will possibly signify the future state of inventory in any SC member. Moreover, the level of holding or reducing the inventory can be determined from the SC cost-impact rules. Thus, the SC cost-impact rules that are derived using the proposed approach greatly facilitate optimal inventory control and hence make the supply chain management more effective.

Keywords-SC cost; SC cost-impact rule; EMA-based inventory; Apriori; Genetic Algorithm (GA).

Abstract— it is important for Digital watermarking to have digital data and multimedia, such as video, music, text, and image copyright protection because of network and multimedia techniques that easily copy. One of the significant problems in video watermarking is the Geometric attacks. In this paper new robust watermarking algorithm has been proposed, based on spatial domain which is robust against geometric attacks such as downscaling, cropping, rotation, and frame dropping. Besides, the embedded data rate is high and robust. The experimental results show that the embedded watermark is robust and invisible. The watermark was successfully extracted from the video after various attacks.

Keywords- Video watermarking, geometric attacks, copyright protection.

Abstract—In Wireless Sensor Networks (WSN), the protocols that are accessible today have their own set of problems and most of them deal with energy efficiency. There is no specific work done on high network traffic or contention issue and significant work is remaining related to robustness and reliability. An important topic addressed by the wireless sensor networks community has been in-network data aggregation, because of the severe energy constraints of sensor nodes and the limited transport capacity of multihop wireless networks. In this paper, we propose to design an energy efficient reliable multipath routing protocol for data gathering in wireless sensor networks. This protocol is intended to provide a reliable transmission environment with low energy consumption, by efficiently utilizing the energy availability of the forwarding nodes to gather and distribute the data to sink, according to its requirements. By simulation results, we show that our proposed algorithm attains good packet delivery ratio with reduced energy consumption and delay.

Abstract—This paper addresses an interesting security problem in wireless ad hoc networks: the Dynamic Group Key Agreement key establishment. For secure group communication in an Ad hoc network, a group key shared by all group members is required. This group key should be updated when there are membership changes (when the new member joins or current member leaves) in the group. In this paper, We propose a novel, secure, scalable and efficient Region-Based Group Key Agreement protocol (RBGKA) for ad-hoc networks. This is implemented by a two-level structure and a new scheme of group key update. The idea is to divide the group into subgroups, each maintaining its subgroup keys using Group Diffie-Hellman (GDH) Protocol and links with other subgroups in a Tree structure using Tree-based Group Diffie-Hellman (TGDH) protocol. By introducing region-based approach, messages and key updates will be limited within subgroup and outer group; hence computation load is distributed among many hosts. Both theoretical analysis and experimental results show that this Region-based key agreement protocol performs better for the key establishment problem in ad –hoc network in terms of memory cost, computation cost and communication cost.

Abstract – The JPEG processing algorithm works best on photographs and paintings of realistic scenes with smooth variations of tone and colour but is not well suited to files that will undergo multiple edits. The direct conversion of jpeg image into binary format is very low in efficiency. In this paper, the process of conversion of jpeg image to binary image is being done in a step by step manner, without using direct inbuilt function of jpeg to binary in MATLAB. As the binary image is used for comparison purposes, the jpeg image is converted into LAB format to make the luminance scale perceptually more uniform, so that the procedure becomes more efficient.

Keywords: LAB, Binary image, sign language

Abstract - This paper reports work done in the E-Tourism project. The overall goal of the project is to improve information creation, maintenance and delivery in the tourism industry by introducing semantic technologies. This paper analyzes the weakness of keyword based techniques and proposes need for semantic based intelligent information retrieval for tourism domain. The Semantic Web is an evolving development of the World Wide Web in which the meaning of information and services on the web is defined, making it possible for the web to understand and satisfy the requests of people and machines to use the web content. It also supports the transparent exchange of information and knowledge among collaborating e-business organizations. It focuses meaningful exchange of knowledge between organizations. Major challenge faced by the semantic web application is modeling of ontology and ontology based information retrieval. The software framework has been developed using Protégé tool for Travels and Tourism domain. This framework facilitates creation and maintenance of ontology. The paper also proposes two methods for information retrieval namely top down and bottom up approach. A comparison of these two approaches also presented in the paper.

Abstract - In traditional VQ - data hiding schemes secret data is hidden inside index based cover image resulting in limited embedding capacity. To improve the embedding capacity as well as to have minimum distortion to carrier media, we have proposed one novel method of hiding secret data into the codebook. In this paper we have used four different algorithms Linde Buzo and Gray (LBG), Kekre’s Proportionate Error (KPE), Kekre’s Median Codebook Generation algorithm (KMCG) and Kekre’s Fast Codebook Generation Algorithm (KFCG) to prepare codebooks. It is observed that KFCG gives minimum distortion.

Abstract - A lot of image registration techniques have been developed with great significance for data analysis in medicine, astrophotography, satellite imaging and few other areas. This work proposes a method for medical image registration using Fast Walsh Hadamard transform. This algorithm registers images of the same or different modalities. Each image bit is lengthened in terms of Fast Walsh Hadamard basis functions. Each basis function is a notion of determining various aspects of local structure, e.g., horizontal edge, corner, etc. These coefficients are normalized and used as numerals in a chosen number system which allows one to form a unique number for each type of local structure. The experimental results show that Fast Walsh Hadamard transform accomplished better results than the conventional Walsh transform in the time domain. Also Fast Walsh Hadamard transform is more reliable in medical image registration consuming less time.

Abstract - Computer security in today’s networks is one of the fastest expanding areas of the computer

industry. Therefore protecting resources from intruders is a difficult task that must be automated so that it is efficient and responsive. Most intrusion-detection systems currently rely on some type of centralized processing to analyze the data necessary to detect an intruder in real time. A centralized approach can be vulnerable to attack. If an intruder can disable the central detection system, then most protection is weakened. The paper presented here demonstrates that independent detection agents can be run in a distributed fashion at three levels, each operating mostly independent of the others, thereby cooperating and communicating with the help of mobile agents to provide a truly distributed detection mechanism without a single point of failure. The agents can run along with user and system applications without much consumption of system resources, and without generating much amount of network traffic during an attack.

Abstract—In this paper we propose a simple method to detect Black hole attacks in the Ad hoc On Demand Vector (AODV) routing protocol. Even if many previous works focused on authentication and cryptography techniques, nevertheless these techniques suffer from some weaknesses. In fact, this kind of solution is just a first line of defense, which should be completed by an intrusion detection system as a second line. The second line which is proposed here consists of including the source route in the header of the control packets (RREQ). In addition to that, any intermediate node records the sequence number of the destination. Thus, if the packet is compromised, the destination node can easily retrieve the address of the attacker. To secure RREP packets, any intermediate node records the addresses of the nodes to which it forwards RREQ. Thus, any node receiving RREP can check if the sender is legitimate or not. Simulation results show the robustness of our protocol and that it allows delivering a high ratio of data and consumes less route establishment delay.

Abstract— The smart antenna array is a group of antennas in which the relative phases of the respective signals feeding the antennas are varied in such a way that the effective radiation pattern of the array is reinforced in a desired direction and suppressed in undesired directions. Smart antenna are the array with smart signal processing algorithms used to identify spatial signal signature such as the direction of arriving of the signal, and use it to calculate beam forming vector, to track and locate the antenna beam on the mobile/target. An array antenna may be used to point a fixed radiation pattern, or to scan rapidly in azimuth or elevation. This paper explains the architecture; evolution of smart antenna differs from the basic format of antenna. The paper further discusses different Beamforming schemes and algorithms of smart antenna array.

Abstract- In this paper, we analyze four authentication protocols of Bindu et al., Goriparthi et al., Wang et al. and Holbl et al.. After investigation, we reveal several weaknesses of these schemes. First, Bindu et al. protocol suffers from an insider impersonation attack if a malicious user obtains a lost smart card. Second, both Goriparthi et al. and Wang et al. protocols cannot withstand a DoS attack in the password change phase, i.e. an attacker can involve the phase to make user’s password never be used in subsequent authentications. Third, Holbl et al. protocol is vulnerable to an insider attack since a legal but malevolent user can deduce KGC’s secret key.

Abstract — Measurement lies at the heart of many systems that govern our lives. Measurement is essential to our daily life and measuring has become a common place and well accepted. Engineering discipline use methods that are based on models and theories. Methodological improvements alone do not make an engineering discipline. Measurement encourages us to improve our processes and products. This paper examines the realm of software engineering to see why measurement is needed and also set the scene for new perspective on software reliability metrics and its improvement. Software measurement is not a mainstream topic within software engineering rather it is a diverse collection of fringe topics. Unlike other engineering discipline measurement must become an integral part of software engineering practice.

Abstract - The face recognition includes enhancement and segmentation of face image, detection of face boundary and facial features, matching of extracted features, and finally recognition of the face. Though a number of algorithms are devised for face recognition, the technology is not matured enough to recognize the face of a person since the algorithm deal with significant amount of illumination variation in image. We propose a new image preprocessing algorithm that compensates for the problem. The proposed algorithm enhances the contrast of images by transforming the values in an intensity image, so that the histogram of the output image is approximately uniformly distributed on pixel. Our algorithm does not require any training steps or reflective surface models for illumination compensation. We apply the algorithm to face images prior to recognition. Simulation is done using seventy five web camera images using Mat lab 7.0.

Abstract - Webpage classification plays an important role in information organization and retrieval. It involves assignment of one webpage to one or more than one predetermined categories. The uncontrolled features of web content implies that more work is required for webpage classification compared with traditional text classification. The interconnected nature of hyper text, however, carries some features which contribute to the process, for example URL features of a webpage. This study illustrates that using such features along with features of sibling pages, i.e. pages from the same sibling, as well as Bayesian algorithm for combining the results of these features, it would be possible to improve the accuracy of webpage classification based on this algorithm.

Keywords: classification, hyper text, URL, sibling pages, Bayesian algorithm

Abstract—With the advancement of technology and reduced storage costs, individuals and organizations are tending towards the usage of electronic media for storing textual information and documents. It is time consuming for readers to retrieve relevant information from unstructured document collection. It is easier and less time consuming to find documents from a large collection when the collection is ordered or classified by group or category. The problem of finding best such grouping is still there. This paper discusses the implementation of k-Means clustering algorithm for clustering unstructured text documents that we implemented, beginning with the representation of unstructured text and reaching the resulting set of clusters. Based on the analysis of resulting clusters for a sample set of documents, we have also proposed a technique to represent documents that can further improve the clustering result.

Abstract - Wireless Local Area Networks (WLANs) are gaining recognition as they are fast, cost effective, supple and easy to use. The networks face a serious of issues and challenges in establishing security to the users of the network. With users accessing networks remotely, transmitting data by means of the Internet and carrying around laptops containing sensitive data, ensuring security is an increasingly multifarious challenge. Therefore it is necessary to make sure the security of the network users. In order to provide network security many techniques and systems have been proposed earlier in literature. Most of these traditional methods make use of password, smart cards and so on to provide security to the network users. Though these traditional methods are effective in ensuring security they posses some limitations too. The problem with these traditional approaches is that there is possibility to forget the password. Moreover, compromised password lead to a fact, that unauthorized user can have access to the accounts of the valid user. This paper proposes an approach for network security using biometrics and deniable authentication protocol. The human biometrics like hand geometry, face, fingerprint, retina, iris, DNA, signature and voice can be effectively used to ensure the network security. The diverse phases included in this proposed approach are user registration, fingerprint enhancement, minutiae point extraction, mapping function and deniable authentication protocol. Furthermore, biometric authentication systems can be more convenient for the users since it involves no password that might be feared to be forgotten by the network users or key to be lost and therefore a single biometric trait (e.g., fingerprint) can be used to access several accounts without the burden of remembering passwords. This proposed paper also explains some of the fingerprint enhancement techniques to make the biometric template noise free. Experiments are conducted to evaluate

the performance measure of the proposed approach.

Abstract - Key management in the ad hoc network is a challenging issue concerning the security of the group communication. Group key management protocols can be approximately classified into three categories; centralized, decentralized, and distributed. The most suitable solution to provide the services like authentication, data integrity and data confidentiality is the establishment of a key management protocol. This paper proposes an approach for the design and analysis of region-based key management protocols for scalable and reconfigurable group key management in Mobile Ad Hoc Networks (MANETs). Most of the centralized key management protocols arises an issue on data security on group communication. The proposed region-based group key management protocol divides a group into region-based subgroups based on decentralized key management principles. This region-based group key management protocols deal with outsider attacks in MANETs to preserve the security properties. A performance model to evaluate the network traffic cost generated for group key management in the proposed region-based protocol for MANETs is developed. Cost for joining or leaving the group and the cost for group communication are considered in evaluating the performance of the proposed region-based group key management scheme.

Abstract - Rapid prototyping has been used for exploring vague user requirements in the front-end of the software life cycle. Automated rapid prototyping may reduce cost of prototyping and the time of developing it .One automated rapid prototyping technique is the direct execution of a specification. Direct execution of a specification has the benefits of quick construction of the prototype, direct support for formal specification, and quick response to the specification changes. However existing formal specification languages still have difficulties in specifying software systems such as non functional behavior of the systems. For non-executable formal specification languages, a prototype may be derived from the specification via software transformations. This approach to rapid prototyping uses a formal specification language to automatically generate a prototype in Prolog via a set of software transformation rules. Because there is a direct correspondence between the language and Prolog, the transformation is mechanical and straight forward. Specifiers can concentrate on generating the prototype without the distraction of transforming one notation into another. This formal specification language may not provide enough abstractions for provide enough abstraction for prototyping some particular features of systems. Therefore, this approach is designed to support the derived prototype to be extended or modified in a modular manner. The specification is written in modules in terms of the language patterns that support module independence, the prototype is then derived in a modular way that supports the ease of modifications to the prototype. The software transformation rules used for the derivation of prototypes in Prolog are presented. In this paper, we apply this specification on the implementation for atomic object Read/Write shared memory in mobile ad hoc network.

Abstract – The conventional design of PSS (power system stabilizers) was carried out using a linearized model around the nominal operating point of the plant, which is naturally nonlinear. This limits the PSS performance and robustness. In this paper, we propose a new design using RNN (recurrent neural networks) and the model free approach (MFA) based on the FEP (feed-forward error propagation) training algorithm [15]. The results show the effectiveness of the proposed approach. The system response is less oscillatory with a shorter transient time. The study was extended to faulty power plants.

Abstract - The authentication system stores the password in a Central Server, and the possibility for the intruder to obtain the password is very easy and can gain access to the contents of the user. For the purpose of authentication, the multi-server systems we proposed to communicate with one or all of the servers. It requires high communication bandwidth at the same time is not easy to maintain and also the protocols are highly expensive. The Two Server Authentication System avoids this problem, which uses the passwords and the session keys, rather than performing the cryptographic techniques. It consists of two servers, the front end and the back end server. The front end server communicates with the user, whereas the back end control server is only visible to the service server. These two servers are responsible for the authentication. The password is split into two words, which is one with the service server and the other with the control server. Both the servers are validated during the form validation process. The system is suitable for both the computation and communication system. The servers are also used for the multiple clients and also for the single server systems.

Abstract --- The findings of recent studies are showing strong evidence to the fact that some aspects of biogeography can be adaptively applied to solve specific problems in science and engineering. This paper presents a hybrid biologically inspired technique called the ACO2/PSO/BBO (Ant Colony Optimization2/Particle Swarm Optimization / Biogeography Based Optimization) Technique that can be adapted according to the database of expert knowledge for a more focussed satellite image classification. The hybrid classifier explores the adaptive nature of Biogeography Based Optimization technique and therefore is flexible enough to classify a particular land cover feature more efficiently than others based on the 7-band image data and hence can be adapted according to the application. The paper also presents a comparative study of the proposed classifier and the other recent soft computing classifiers such as ACO, Hybrid Particle Swarm Optimization – cAntMiner (PSO-ACO2), Hybrid ACO-BBO Classifier, Fuzzy sets, Rough-Fuzzy Tie up and the Semantic Web Based classifiers with the traditional probabilistic classifiers such as the Minimum Distance to Mean Classifier (MDMC) and the Maximum Likelihood Classifier (MLC). The proposed algorithm has been applied to the 7-band cartoset satellite image of size 472 X 576 of the Alwar area in Rajasthan since it contains a variety of land cover features. The algorithm has been verified on water pixels on which it shows the maximum achievable efficiency i.e. 100%. The accuracy of the results have been checked by obtaining the error matrix and KHAT statistics .The results show that highly accurate land cover features can be extracted effectively when the proposed algorithm is applied to the 7-Band Image , with an overall Kappa coefficient of 0.982.

Abstract—Due to the irrelevant patterns and noise of network data, most of network intrusion detection sensors suffer from the false alerts which the sensors produce. This condition gets worse when deploying intrusion detection measures in real-time environment. In addition, most of the existing IDS sensors consider all network packets features. Using all packets features for network intrusion detection will result in lengthy and contaminated intrusion detection. In this research we highlight the necessity of using important features in various anomaly detection cases. The paper presents a new multi-classifier system for intrusion detection. The basic idea is to quantify the causal inference relation to attacks and attacks free data to determine the attack detection and the severity of odd packets. Initially, we have refined the data patterns and attributes to classify the training data and then we have used the SOM clustering method and the fuzzy cognitive maps diagnosis to replicate attacks and normal network connection. Experimental results shows that the classifiers gives better representation of normal and attack connection using significant features.

Abstract— AccSearch is a specialized web search engine to provide information about road accidents within Chennai, India and assist the traffic authorities, police, NGOs, lawyers, students and statistical bureaus. The people who are in need of road accident information for various reasons are very much struggling to collect the correct information under a single search. Special purpose search engines are designed to work on a particular domain which fill the gap where an all purpose search engine lacks. As the existing search engines cannot do the traffic search alone well for several reasons, we have designed a search algorithm using Markov chain, to provide the search information in a faster manner. The mathematical proof of our modified Markov chain algorithm shows that the speed and efficiency seems to be better in comparison with the existing search algorithms. As Markov chain can be used for prediction purposes, our search engine concentrates on one particular domain which is traffic analysis it will result in exact responses to the user queries and will lead to a greater amount of user satisfaction.

Abstract—: In this paper, a smart card based on line health care system and its performance issues using SQL server are proposed. To provide a good quality of treatment in the hospital, it is required to integrate all the hospitals of country via internet. A Smart Card with 10 digits unique registration no. with his some personal information is issued to patient. After getting registration in any hospital of the hospital network, patient has to go for checkup with smart card only. All the patient information i.e. personal, doctor prescriptions, test reports etc. will be stored in the database of the local server of the hospital and time to time uploaded to the centralized server. On the basis of unique registration no., all the patient information can be retrieved from the database of the centralized server. Smart card based online health care system application has been designed as front end .Net and back end in SQL server. The block size or page size being used during the database creation is playing very important role in performance tuning. It is very important to decide the proper block size before database design. You cannot change the block size once you have created the database. Recreating the database again is a very costly affair.

Abstract— In this study, having reviewed the automatic surfaces inspection and it’s benefits compared to the handcrafted inspection, we will explain the wavelet transformation method with an emphasis on it. There are various methods for image segmentation. Yet, in this essay, we will use the wavelet transformation for segmentation of steel colorful plates to areas of normal and defective. Each image needs to be converted to RGB, HSL, LAB color spaces. Afterward, considering a color space, discrete wavelet transformation is applied to three dimensional channels of the image and detailed images at various levels are obtained. Due to visible differences in normal and defective areas, it is expected that defective areas have clear borders with normal areas in some detailed images and in some way clustering the image to the areas of defective and normal be possible. Finally, the results obtained from different colorful channels are compared. It is worth mentioning that the tests have been done on a set of images of normal and defective steel surfaces, showing the quality of wavelet method.

Abstract—Mobile Ad-hoc Networks (MANETs) are future wireless networks consisting entirely of mobile nodes that communicate on-the-move without base stations. Nodes in these networks generate user and application traffic and carry out network control and routing functions. Dynamic and random topologies lead to rapidly changing connectivity and network partitions. This dynamic nature along with bandwidth and power constraints together pose new problems in network scalability, network control, especially in the design of higher level protocols such as routing, and in implementing applications with Quality of Service requirements. Hierarchical routing provides a means to tackle the above mentioned problems in large scale networks. Clustering is the process of building hierarchies among nodes in the network. In this approach an ad hoc network is partitioned into group of nodes called as clusters. This paper presents a review of the different clustering algorithms and the criterion on the basis of which each of them takes the clustering decisions.

Abstract— The nearest neighbor (NN) technique is very simple, highly efficient and effective in the field of pattern recognition, text categorization, object recognition etc. Its simplicity is its main advantage, but the disadvantages can’t be ignored even. The memory requirement and computation complexity also matter. Many techniques are developed to overcome these limitations. NN techniques are broadly classified into structure less and structure based techniques. In this paper, we present the survey of such techniques. Weighted kNN, Model based kNN, Condensed NN, Reduced NN, Generalized NN are structure less techniques whereas k-d tree, ball tree, Principal Axis Tree, Nearest Feature Line, Tunable NN, Orthogonal Search Tree are structure based algorithms developed on the basis of kNN. The structure less method overcome memory limitation and structure based techniques reduce the computational complexity.

Abstract — In this paper, we attempt to diagnose the occurrence of faults in analog electronic circuits based upon variations in time domain specifications corresponding to the circuit condition under consideration relative to the fault free circuit. To achieve this, both a fuzzy as well as a neural classifier have been utilized to operate with the fault dictionary data as base. Through this process, a general comparison is drawn out between the performance of either route in dealing with fault diagnosis of circuits. An illustrative example is considered, on which both the fuzzy and neural algorithms are tested, and their performance in fault diagnosis is compared. Further, the suitability of the fuzzy and neural techniques to various kinds of diagnosis problems depending upon the nature of data available is also discussed.

Abstract — To date publish of a giant social network jointly from different parties is an easier collaborative approach. Agencies and researchers who collect such social network data often have a compelling interest in allowing others to analyze the data. In many cases the data describes relationships that are private and sharing the data in full can result in unacceptable disclosures. Thus, preserving privacy without revealing sensitive information in the social network is a serious concern. Recent developments for preserving privacy using anonymization techniques are focused on relational data only. Preserving privacy in social networks against neighborhood attacks is an initiation which uses the definition of privacy called k-anonymity. k-anonymous social network still may leak privacy under the cases of homogeneity and background knowledge attacks. To overcome, we find a place to use a new practical and efficient definition of privacy called ldiversity. In this paper, we take a step further on preserving privacy in collaborative social network data with algorithms and analyze the effect on the utility of the data for social network analysis.

Abstract — This paper deals with an improvement of vertex based nonlinear diffusion for mesh denoising. This method directly filters the position of the vertices using Laplace, reduced centered Gaussian and Rayleigh probability density functions as diffusivities. The use of these PDFs improves the performance of a vertex-based diffusion method which are adapted to the underlying mesh structure. We also compare the proposed method to other mesh denoising methods such as Laplacian flow, mean, median, min and the adaptive MMSE filtering. To evaluate these methods of filtering, we use two error metrics. The first is based on the vertices and the second is based on the normals. Experimental results demonstrate the effectiveness of our proposed method in comparison with the existing methods.

Keywords- Mesh denoising, diffusion, vertex.

Abstract — Risk estimation is a necessary step in risk management which is the measurement of impact caused by the probability of exploiting vulnerabilities recognized in the system. At the moment, the qualitative metrics are used for this purpose that is believed to suffer subjectivity. The risk caused by a recognized vulnerability is computed using the values of common vulnerabilities scoring system (CVSS) attributes. But the great challenge in this field is that the dependency between vulnerabilities recognized in the system is not taken into account. In this paper, a new approach to risk assessment for the risks caused by vulnerabilities of system has been proposed which considers the dependencies among vulnerabilities. This approach consists of three steps. In the first step, after recognizing vulnerabilities of system and configuring the system, an attack graph is generated for all the critical resources of the system using MulVAL framework. Using these attack graphs, the dependency among vulnerabilities is extracted. In the second step, using the dependencies extracted among the vulnerabilities and estimated impact and exploitability defined based on CVSS attributes for individual vulnerability, a Markov model is generated. In the third step, using the Markov model, the quantitative security risk is estimated as the attacker keeps progressing in the system. In this paper we introduce the proposed approach, a case study demonstrating the above steps and the results of quantitative security risk estimation.

Abstract— In this paper, we propose a new technique for image super-resolution. Given a single low resolution (LR) observation and a database consisting of low resolution images and their high resolution versions, we obtain super-resolution for the LR observation using regularization framework. First we obtain a close approximation of the super-resolved image using learning based technique. We learn high frequency details of the observation using Discrete Cosine Transform (DCT). The LR observation is represented using a linear model. We model the texture of the HR image using marginal distribution and use the same as priori information to preserve the texture. We extract the features of the texture in the image by computing histograms of the filtered images obtained by applying filters in a filter bank and match them to that of the close approximation. We arrive at the cost function consisting of a data fitting term and a prior term and optimize it using Particle Swarm Optimization (PSO). We show the efficacy of the proposed method by comparing the results with interpolation methods and existing super-resolution techniques. The advantage of the proposed method is that it quickly converges to final solution and does not require number low resolution observations.

Abstract— Enterprise resource Planning (ERP) has become a key business driver in today’s world. Retailers are also trying to reap in the benefits of the ERP. In most large Indian Retail Industry ERP systems have replaced nonintegrated information systems with integrated and maintainable software. Retail ERP solution integrates demand and supply effectively to help improve bottom line. The implementation of ERP systems in such firms is a difficult task. So far, ERP implementations have yielded more failures than successes. Very few implementation failures are recorded in the literature because few companies wish to publicize their implementation failure. This paper explores and validates the existing literature empirically to find out the critical success factors that lead to the success of ERP in context to Indian retail industry. The findings of the results provide valuable insights for the researchers and practitioners who are interested in implementing Enterprise Resource Planning systems in retail industry, how best they can utilize their limited resources and to pay adequate attention to those factors that are most likely to have an impact upon the implementation of the ERP system.
