by Xia Wendong, Liu Yuanfeng, Chen Deli
Abstract: Aiming at the fact that the algorithm communication time occupation ratio is too high and the practical application value is limited under the Mapreduce mechanism, a Hadoop-based two stage parallel c-Means clustering algorithm is proposed to solve the classification problem of super large data. First, the Hadoop-based two stage parallel fuzzy c-Means clustering algorithm is proposed to process the clustering of large data; and a protocol-based group typical individual reduction strategy is used to improve the time complexity of the MPI communication model of Mapreduce, so as to improve the overall efficiency of the algorithm; secondly, the interference of bad data items can be effectively eliminated by the selective group reduction algorithm, so that the algorithm in this paper has higher operating efficiency and clustering success rate. In terms of parallel rate and speedup ratio, the parallel rate and speedup ratio of the proposed algorithm in this paper on the large data set is better than the performance of the small data set, which means that the algorithm in this paper can adjust itself according to the amount of data in real time. The simulation results show that the performance of PGR-PFCM algorithm is better in the processing of large data.

by Nazori Agani, Arfian Maulidan
Abstract: String Search or the string matching is one aspect that is very important in terms of data processing, in addition the problem string matching is also one of the problems that are well known in the world of informatics. Some examples of the implementation of the string matching problem is in matching a string in a text editor application such as Microsoft Word, or in the case of bigger, ie matching website by entering key words as it has been implemented on search engines such as Google Inc. The general process in the searching a string is looking for a string that consists of some of the characters (called pattern) in a large amount of text. Search string is also used to look for patterns of bits in a large number of binary files. Problems begin to arise if the search process occurs in a lot of data and complex, of course, this would be very time-consuming and resources owned, so the search technique effectively and efficiently will be needed. The purpose of this study is to utilize a String Matching algorithm that is by using the Boyer-Moore-Horspool in the search data is a list of financial terms. Boyer-Moore algorithm-Horspool used to search for any string precision (word or phrase) entered with a high degree of accuracy of search, because it uses pattern matching from right to left. In addition to the HTML5-based application model, application model matching string can later be run multiplatform not only on mobile devices, but also be able to run on a desktop browser.

by Mohd Khaled Shambour
Abstract: Evolutionary algorithms (EAs) have been extensively used since their invention. EAs are considered as a powerful tool to solve numerous optimization problems in various fields. Their search mechanisms have been actively developed to improve their search efficiency toward global optima solutions. This study aims to investigate the effects of using different types of recombination (crossover) schemes. It introduces an adaptive version of EA called adaptive multi-crossover evolutionary algorithm (AMCEA). The proposed AMCEA offers multiple forms of heuristic crossover operators based on genetic algorithm (GA) and harmony search algorithm (HSA). The proposed technique improves the search attitude by allowing the effective utilization of exploration and exploitation strategies during the evolution process. The quality of the proposed AMCEA is evaluated on six real-world numerical optimization problems (IEEE-CEC2011), and results are compared with those obtained with five variants of GA and HSA. Results demonstrate the superiority of the AMCEA over previously improved algorithms in terms of solution quality; it achieves the lowest mean results and lowest best results in 75% and 66% of the total experiment cases, respectively.

by Haripriya D, Govindaraju C, Sumathi M
Abstract: Temperature aware adaptive voltage scaling based low power 8 bit Multiplier-Accumulator (MAC) architecture for Digital Signal Processing (DSP) has been presented in this paper. Temperature increases dynamic power, static power and leakage power dissipation in the electronic circuits, hence it is mandatory to construct a circuit which minimizes the dynamic power, static power and leakage power adaptively according to the current temperature so that the performance of the overall system is not degraded much. The proposed temperature aware adaptive voltage scaling is very effective method to minimize the dynamic power, static power and leakage power consumption without degrading the performance of the system. The dynamic power consumed by the conventional MAC is 3.441mW when the temperature is 150

INCORPORATING NOUN COMPOUNDS IN DISTRIBUTIONAL-BASED SEMANTIC REPRESENTATION APPROACHES FOR MEASURING SEMANTIC RELATEDNESS
by Abdulgabbar Saif, Nazlia Omar, Ummi Zakiah Zainodin
Abstract: Identifying noun compounds in natural language documents is very important for handling their various linguistic features, such as semantic, syntactic, and pragmatic features. In this study, we introduce a knowledge-based method for incorporating noun compounds in distributional-based semantic representation approaches. Wikipedia is exploited as a knowledge resource for extracting noun compounds based on its structural features. The categories are then used to classify the extracted noun compounds as linguistic terms and named entities. Next, the look-up list technique is employed to identify the noun compounds when extracting the semantics of the terms using the corpus-based approach for semantic representation. To obtain the semantic representation, we use five well-known distributional-based approaches: latent semantic analysis (LSA), hyperspace analogue to language (HAL), correlated occurrence analogue to lexical semantic (COALS), bound encoding of the aggregate language environment (BEAGLE), and explicit semantic analysis (ESA). The proposed method was evaluated by measuring the semantic relatedness using five benchmark datasets employed in previous studies. The experimental results demonstrate that incorporating noun compounds in the distributional-based semantic representation helps to improve the semantic evidence for the relationships among words.
Keywords: Distributional-based approach; Noun compound; Semantic analysis; Semantic relatedness.

by Min Zhang, Rui Qi
Abstract: Decision demand has hierarchies for different users and the decision analysis demand in various area and field have particularity according to different topics. Since traditional MIS is hard to meet the demand of analysis and processing of growing mass data, a novel decision support system(DSS) is urgent to be proposed for decision makers. Based on data warehouse, data mining and OLAP technology, we propose a DSS with modular design, and explain the structure and key technologies of it in this article. Our study establishes multidimensional data-set for OLAP analysis to perform slicing, dicing, drilling and rotation operation. In data mining, for the problems of large data-set such as long learning time and decreasing generalization ability, an SVM accelerating algorithm based on boundary sample selection is put forward. The system test results demonstrate that the data mining has better prediction effects on economical forecasting. Therefore, the research has better practicability and higher accuracy, which shows certain value of popularization and implementation.

Toward an Automatic Summarization of Arabic Text Depending on Rhetorical Relations
by Samira Lagrini, Nabiha Azizi, Mohammed Redjimi, Monther Al dwairi
Abstract: Rhetorical relations between two text segments are crucial information and have been proven useful for many natural language processing (NLP) applications. In this paper, we propose a supervised approach for automatic identifying of rhetorical relations in Arabic texts. To the best of our knowledge, this is the first model that attempts to identify both implicit and explicit rhetorical relations between elementary discourse units within the rhetorical structure theory (RST). To carry out this research, we developed a discourse annotated corpus following the RST framework with high reliability.Relations annotation was done using a set of 23 fine-grained relations enriched with nuclearity annotation. To automatically learn these relations, we reuse some state of the arts featuresand contribute new lexical and semantics' features. The experimental results, on fine-grained and coarse-grained relations, showed that our model achieved the best performance relative to all baselines

MGA-TSP: Modernized Genetic Algorithm for the Traveling Salesman Problem
by Ra'ed M. Al-Khatib
Abstract: This paper proposes a new enhanced algorithm called Modernized Genetic Algorithm for solving the Traveling Salesman Problem (MGA-TSP). Recently, the most successful evolutionary algorithm used to solve the TSP problem, is the GA algorithm. One of the main obstacles for GA is building its initial population. When initiating the GA with a strong initial population, the convergence rate and the diversity aspect will be more stronger. Therefore, in this paper, a new local search mechanism based on three neighborhood structure operators (Inverse, Insert, and Swap) along with 2-opt is utilized. This adapted neighborhood structure operators are employed to generate the initial population for GA algorithm. In addition to building powerful initial population for TSP, the main operators (i.e., crossover and mutation) of GA during the generation process should be also enhanced for TSP. Therefore, the recent and powerful crossover operator called EAX is utilized in the proposed MGA-TSP to enhance its convergence behavior. In order to validate the performance of the proposed algorithm we used TSP datasets, have different complexities and sizes. The sizes of the dataset-cities, range from 150 to 33810 cities. Initially, the impact of each neighboring operator on the performance of the proposed algorithm is studied. In conclusion, our proposed method achieved the best results. For comparative evaluation, the results obtained from our proposed MGA-TSP method is compared with those obtained by six well-regard methods using the same TSP instances. The proposed method is able to outperform other comparative methods in almost all TSP instances used.

by S.K. Lakshmanaprabu, U. Sabura Banu
Abstract: The development and real time implementation of multivariable centralized FOPID (MC-FOPID) controllers for two interacting frustum conical tank level process (TICFTLP) is presented. The Modeling and control of TICFTLP is difficult due to its dynamic coupling between inputs and outputs. The black box model is developed from the open loop experimental data using process reaction curve method (PRC). The multivariable centralized FOPID (MC-FOPID) controller with five tuning parameters is designed based on the steady state gain matrix of the process and then the controller parameters are tuned using bat optimization algorithm. The comparison of proposed MC-FOPID controller with multiloop PID controller is demonstrated in the simulation study. The simulation results of the controllers are compared in terms of settling time and integral error criteria. It is found that the MC-FOPID controller has better servo and regulatory response than multiloop PID control. The real time implementation of MC-FOPID is done in MATLAB/SIMULINK using USB based DAQ module.

Exploiting Ontology to map requirements derived from informal descriptions
by Murugesh Sundaram, Jayal A
Abstract: Requirements are narration of the services which a software system should make available along with the constraints that should be satisfied when the system operates. Software requirements have to be arrived from descriptions that are often incomplete, inconsistent, informal and ambiguous . Such informal descriptions have to be preprocessed and information constructs have to be extracted. This article deals with use of an ontology specific to Automatic Teller Machine(ATM) operations domain that contains the concepts, the relationships that exists among the concepts and the focus is to decide on the feasibility of the requirement by mapping the extracted requirement with the requirement defined in the background ontology. The developed ontology is queried using Simple Protocol and RDF Query Language (SPARQL), if the derived requirement is present in the ontology it is said to be feasible; else decision may be taken to eliminate the requirements that are invalid and infeasible. Ontology is a formal specification of concepts with their attributes and relationship in a particular domain. As standard description formalism, the Web Ontology Language (OWL) that is based on Resource Description Framework (RDF) is to be used.

Trusted computing in Social Cloud
by Priya Govindaraj, Jaisankar Natarajan
Abstract: Social Cloud is a new paradigm which allows a user to share the system resources for computing purposes when it is not otherwise being used. This paper focuses on the computing model Social Cloud where the computing nodes are managed by the social bonds determined from a trust retaining social graph. It can be considered as a situation of a computing method in which cloud users gather a group of resources to do computational tasks for the sake of a social friend. So whenever a task is given by a user, the burden of computing is passed to the friend, i.e. to the nodes which are directly connected to them in the social network. We have used two different scheduling algorithms namely FCFS and Round Robin to check the performance statistics of the Social Cloud and state which algorithm is best suitable for the implementation. Apart from this we have proposed a new index called Trust Index for calculating the trust value of a user and also to find out whether a user is trustworthy or not. The proposed Trust Index mainly fills the gap of human interaction in evaluating a users trustworthiness, since here a user decides whether or not to trust another user. To show the efficiency of this trust index we have created a social network with a feature of verifying a friend, by using which we can verify our friends and make them trustworthy.

by Karthikeyan B, Kumar R, Srinivasa Rao Inabathini
Abstract: This paper present and analyze an energy efficient data compression and data aggregation algorithm which results in the whole network lifetime prolonged by about 24% . In this paper, a new idea is proposed for sensor values compression based on a technique that involves feedback mechanism. In this technique, the base node in the sensor network generates Huffman code for the sensor data that needs to be compressed and broadcast the Huffman code in to the sensor network. All nodes in the sensor network receives Huffman code, compress the sensor data and transmit to base node. For data aggregation, secure data aggregation algorithm is used which does not necessitate additional phase for data integrity verification and also it eludes extra transmissions and computational overhead on the sensor nodes to reduce the amount of energy used up by the network. The whole idea was tested on TelosB sensor network platform, programmed in nesC language and also analyses the performance of the algorithm in the Contiki OS- simulator Cooja. A comparison is also done with existing compression algorithms in terms of lifetime of the sensor network.

An Intelligent Neuro-Genetic Framework for Effective Intrusion Detection
by Rama Prabha Krishnamoorthy Pakkirisamy, Jeyanthi N
Abstract: Intrusion detection systems are useful for improving the network performance by safeguarding the networks from attacks including flooding attacks. Intrusion detection systems can be developed by identifying the important features from the network data to be analysed and by classifying the network traffic using the most contributing and important features. In this paper, a new intelligent neuro-genetic framework is proposed for detecting the intruders in networks by analysing their behaviour. For this purpose, a new Genetic Algorithm based Feature Selection Algorithm (GAFSA) and a Neuro-Genetic Fuzzy Classification Algorithm (NGFCA) have been proposed in this paper which are used to identify the malicious users through classification of user behaviours. The main advantage of this proposed framework is that it reduces the attacks by identifying the intruders with high accuracy and reduced false positive rate. This work has been tested through simulations and also using bench mark dataset for analysing the performance of the proposed algorithms. From the experiments conducted in this work using full features and selected features by applying the existing classification algorithms as well as the proposed classification algorithm, it is proved that the proposed framework detects the intruders more accurately and reduces the attacks leading to increase in packet delivery ratio and reduction in delay.

by Meenatchi SS, Prabu Sevagan
Abstract: Consumption of energy by the sensor node in wireless sensor node is the main criteria affecting the wireless sensor network. The message transmission of wireless sensor network requires high power consumption and quality of service, which affects the energy consumption in WSN. To overcome the criteria the energy consumption of node is reduced by the proposed EA-PATM protocol. The proposed protocol consists of pillar k-mean clustering method to cluster the network in to set of nodes. For the selection of cluster heads, the ant lion optimization algorithm check the clustered node for effective QoS parameters. Ant lion is a nature inspired optimization algorithm proposed in this paper to generate cluster head for the evaluation of energy consumption in the WSN. The TDMA based MAC protocol is proposed in the paper to evaluate the energy consumed in transmission of information from one cluster node to other during routing. The proposed formulation offer a stable definition for estimating the quality of service performance of network and hence by consuming less energy in wireless sensor network. The proposed technique is carried out in network simulator and the results are plotted in terms of processing energy, nodes remaining energy and QoS parameters such as packet delivery ratio, packet loss ratio, delay, latency, throughput and overheads. From the concluded results, it clearly mentioned that the proposed EA-PATM protocol is an efficient method for consumption of sensor node processing energy and quality of service in wireless sensor networks.

by Nandha Gopal, Roheet Bhatnagar
Abstract: This paper deals with how to identify the cancer affected region of the brain. There have been many tools and techniques such as SOM (Self Organizing Map), PSVM (Proximal Support Vector Machine) classifiers, discovered to find out the cancer affected region in the brain. There is a rapid growth in the brain tumour cases in the recent past. Technology failed to find out the root cause behind it. Recent reports reveal that different types of brain tumours can be treated either through surgery or in rare cases, with radiation. The role of image segmentation in identifying and the treatment of brain tumours are enormous, because image segmentation will help to find out the volume and the growth of the tumours using the techniques like human edge correction, outer edge coloring and inter active thresholds holdings. In order to reduce the human error and to get the accurate results in MRI images there is an urgent need to find out an automatic or semi automatic method for the classification of brain tumor images .Finally a system called Hybrid SP classifier has been developed for the detection and classification of brain cancer, this type of mechanisms uses a system dependent actions to find the block and different types of brain tumours. It also makes the use of some of the mechanisms like Image enhancement, segmentation and Equalization of histogram.

by Kumaresan P, Prabukumar M
Abstract: Embedded Systems are pervasive with the advent of Internet of Things. This has led smart devices to be omnipotent. In future, this will convert any object (living, non-living, smart devices) into smarter devices which finds applications in an unimaginable way. Even though the technology becomes omnipotent, several research problems arise in design and implementation. Problems such as energy consumption, security, quality of information, performance and intelligence are needed to be addressed when it is applied in the health care system, wireless communication, defence, agriculture and so on. Here, we have concentrated on the Low Power Health Care System based on Body Area Networks (BAN) in which the technology embeds the Body Area Networks with Internet of Things (IOT) which can be jointly coined as BIOT (BAN Internet of Things). BIOT finds application as wearable devices for monitoring and care giving systems for patients. Due to BIOTs nature of omnipotent application in the health care, maintaining its life time remains in the darker side of the research. To overcome this problem, a new algorithm for the BIOT called WORN (Wake - On Reconfigurable Networks) has been proposed. The proposed algorithm works on the DEAR (Distance Energy Adaptive Rule) rule sets. This algorithm calculates distance based on RSSI and selects frequency using DEAR rule sets for minimum energy. It has been tested with different transceivers on different architectures. The results obtained from different testbeds have shown a 20-30%of increase in lifetime of the BIOT network. By increasing the life time of the devices, BIOT with WORN-DEAR power model will be the bridge between the human and the machine Interface.

Encrypted Image based Data Hiding Technique Using Elliptic Curve ElGamal Cryptography
by JAYANTHI RAMASAMY, John Singh K
Abstract: Most of the data hiding techniques used RSA based encryption algorithms for encrypting the images and the messages. However, the security provided by elliptic key cryptography is higher with a lower size key than the RSA algorithm. Therefore, a new image encryption scheme which can be reversed during decryption is proposed in this paper which uses an elliptic curve key based ElGamal encryption scheme for effective data hiding in images. Moreover, it uses the difference scheme available in the existing work for data hiding of images. Form the experiments conducted in this work, it is proved that the proposed scheme is more efficient with respect to security and it reduces the computation complexity when it is compared with other related schemes.

IDENTIFICATION OF PERSON OR DATA USING MODIFIED SQUARE BLOCKWISE APPROACH
by Denslin Braja R, Dharun V. S.
Abstract: Nowadays authentication is important to identify the originality of a person or document. Visual Secret Sharing scheme is one of the best methods to provide authentication without any complex computations. In this paper, we proposed novel method called modified square blockwise approach to generate shares. Here the personage photo or any biometric data can be used as an authenticated image. This approach will generate two shares, one share is printed on identity card and the other one is stored on database. To verify the originality of a document or a person, first receive the identity card and scan or take a photo of the share. Now this share is compared with the stored one, if it is reveal the authenticated image then it is accepted, otherwise simply rejected. This approach is used to authenticate any confidential data such as medical document, bank details and administration details also. Using this approach, we can restrict the use of confidential documents without knowing the originality of the document.

by GeethaRamani .R, Revathy .P, Lakshmi .B
Abstract: In this internet world, an increased interest of users in the search of World Wide Web results in wide relevance of Web Mining, which is an application of Data Mining. According to the type of data to be mined, web mining is broadly classified into three categories namely web content mining, web usage mining and web structure mining. Clustering has been widely used for web usage mining. One of the major challenges in the study of clustering is finding the initial cluster center and the number of clusters to be generated. This is overcome in this work by grouping of users based on the target class value. The benchmark dataset MSNBC is collected for msnbc.com and news-related portions of msn.com for the entire day of September, 28, 1999. Supervised Association Rule Tree mining is used to find the frequent itemset for the targeted class value and thus generating "if then rules". Users are automatically clustered based on the rules satisfying the ground truth, resulting in 36 clusters in two iterations. The results revealed that the renowned clustering algorithms such as K-Means takes 22 iterations for forming 36 clusters, wherein the proposed work generates 36 clusters in two iterations efficiently with less computation.

A Secured Cloud Storage Auditing with Empirical Outsourcing of Key Updates
by Vijayakumar K, Suchitra S, Swathi Shri P
Abstract: Cloud Computing is emerging and considered next generation architecture for computing. Cloud storage auditing is regarded as a prominent feature to validate the integrity of the data in public cloud. The key exposure resistance is a vital issue in various security applications. The current cloud storage auditing models require the client to update his secret keys in each time period which bring in local burdens to the client. The aim of the project is to make the key updates transpicuous to the client and present a new model for auditing cloud storage with verifiable outsourcing of key updates. In this model, the key updates are outsourced to a third party auditor (TPA) who reduces the local burden on the client. The third party auditor (TPA) is accountable for both cloud storage auditing and safe key updates. The TPA holds an encrypted version of the clients secret key. The client decrypts the secret key, generates authenticators for the file and uploads these files along with authenticators to the cloud. In our design, we employ the Multi Key Encryption Algorithm to achieve faster key updates, short key size and to proficiently encrypt the secret keys. In addition, the TPA will audit whether the files in cloud are stored correctly by a challenge-response protocol between it and the cloud at regular time. The proposed paradigm permits the client to authenticate the validity of the encrypted secret key produced by the third party auditor for uploading data to the cloud. These prominent features are considered to make the entire cloud storage auditing technique as transpicuous as possible for the client.

A File Sharing System in Peer-to-Peer Network by a Nearness-Sensible Method
by Vimal .S, Srivatsa S.K
Abstract: For a comprehensive Peer-to-Peer file sharing system dynamic file query is substantial where its performance can be enhanced by clustering of peer that can also considerably improve the efficiency. Depending upon physical nearness and peer interest peers are clustered in current work. File replication algorithm has been employed that creates replicas for the requested file to enhance the efficiency. Compared to unstructured P2P the efficiency is high for structured P2P which is difficult to analyze because of their rigid topology. We have developed Nearness and Interested Cluster (NIC) super peer network to improve the efficiency of file location in current years for P2P system but few works rely on peer interest and physical nearness. Various methods have been used to improve intra-sub-cluster searching. Here the interest is categorized into sub-interest then they are linked according to common-interest. File searching delay is minimized where an overlay is built to link. Flower filter is employed to enhance the efficiency and reduce the overhead. On comparing Nearness Sensible I-clustered System with other system the efficiency has been traced. The effect of enhancing the efficiency using intra-sub-cluster searching is observed in experimental results.

MITIGATION OF DDOS THREAT TO SERVICE ATTAINABILITY IN CLOUD PREMISES
by Shiny Duela, Uma Maheswari P
Abstract: Cloud environment provides users with amicable services that help them to attain their organizational and personal goals. The cloud users are provided with immense resources as they require by exploiting the scalability and openness feature of the distributed environment. The heterogeneity masking is an added advantage that facilitates the customers with dissimilar resources to communicate with each other by having common agreed standards. The service models rendered by the cloud on pay as you go basis assist the customers to have large-scale business deals so that the investment to carry out such deals diminishes. To enable full-time availability of such resources, the cloud users should have access to the necessary applications and data when and wherever needed with internet connectivity. The scenario of availability of service differs from the goal of Cloud Service Provider whenever the end user suffers from unavailability and delay of promised services. This is due to Distributed Denial of Service (DDOS) attack where the illegitimate users on cloud who always generate different kinds of bots and zombies to disrupt or breakdown service availability by means of flooding the network and consumption of large network assets. To overcome such scenario, a DDOS Detection Algorithm (DDA) is proposed that trace out the existing attack by employing Action-based Monitoring (AM) approach on the incoming traffic, resource consumption and header information parameters after which the Human Discovery Algorithm (HDA) is implemented by performing a Turing test targeting on human so that bots could be segregated from the normal user. The Supervisor Self Learning Algorithm (SSLA) is another mitigation test that allows future bots to be isolated by referring to the previous attack patterns of bots. This model has shown improvement in terms of client success ratio, load balancing, and detection, prevention and mitigation of DDOS attack with respect to time.

by Suresh .K, Sakthi .U
Abstract: The conventional way in analyzing image segmentation algorithms manually is difficult since it requires a lot of human effort in keeping all data for analysis. Various heuristic algorithms are bundled with Otsus and Kapurs objective function in finding optimal fitness and quality segmentation. In this work Otsus and Kapurs objective function are bundled with heuristics such as Harmony Search Optimization (HSO) and Electro Magnetic Optimization (EMO) to compare the solution accuracy of segmented images In order to statistically analyze such algorithms, an automated tool is developed which takes an input image of any image category under consideration and extracts the segmentedfitness values and quality parameters of the image. The extracted values are stored in a central database server constrained with image type, image category, methodology and heuristic used, no of thresholds and quality parameters. The central repository information is fed into data mining and data analytic tools to statistically rank the segmentation algorithms.

by GeethaRamani .R, Revathy .P, Lakshmi B
Abstract: In this epoch, a significant amount of patterns are retrieved using data mining techniques. Application of data mining techniques to the World Wide Web is referred as Web Mining. Clustering is one of the data mining technique that plays an vital role in the field of Web mining. This paper works on the server logs from the MSNBC dataset for the month of September 1999. Users with the average access length of 6 are used for analysis. This research aims to cluster the user based on their navigation behavior. An iterative aggregated clustering is proposed, in which various clustering algorithms such as EM clustering, Farthest First, K-Means Clustering, Density based cluster, Filtered cluster are applied on the dataset. The resultant clusters from various algorithms are aggregated correspondingly and the frequency of instances in each cluster is determined. If frequency of a instance in a cluster is greater than or equal to two-third majority, then the instance is grouped in that cluster. The work revealed that the system guaranteed to cluster 91% of users in the first iteration under 17 clusters for each page category and 99% of users are clustered in the subsequent iterations in another 17 clusters and rest of the users are grouped as one cluster, resulting in 35 hard clusters. The proposed framework is believed to serve in clustering user groups there by enabling suitable customized web environment.

Unified Dynamic Texture Segmentation System based on Local and Global Spatiotemporal Techniques
by Shilpa Paygude, Vibha Vyas
Abstract: Dynamic Texture (DT) is temporal extension of static texture. There are two broad types of dynamic textures: Natural and Manmade. The examples of dynamic textures are waving tree, sea water, fountain, traffic, moving crowd etc. Dynamic Texture Segmentation is a technique used to separate the moving objects from stationary content in the video. Majority of the techniques give good results either for natural or for manmade dynamic textures. The proposed approach for DT Segmentation is combination of Local Spatiotemporal Technique i.e. Local Binary Pattern-Weber Local Descriptor and Global Spatiotemporal Technique i.e. Contourlet Transform. The local spatiotemporal technique considers the appearance and motion of the object for segmentation. The technique is computationally less complex than optical flow and gives good results for manmade dynamic textures. The Global spatiotemporal technique is based on Laplacian Pyramid and Directional Filters. It gives good results for natural dynamic textures. The proposed technique discussed in this paper is unified approach for any type of Dynamic Texture. The regions of images commonly segmented by both the techniques are considered as the final segmented output. The proposed system works equally well on any kind of Dynamic Texture.

Onboard Reasoning and Other Applications of the Logic-Based Approach to the Moving Objects Intelligent Control
by Andrey Tyugashev
Abstract: This article provides the theoretical background and practical case studies of the application of reasoning and other logic-based approaches to the moving objects control. Modern moving objects, both manned and unmanned, utilize computers as their ‘onboard brain’. Since planes, spacecraft, cars, trucks and trains must demonstrate flexible and safe behavior in various situations, it seems prospective to use intelligent control means instead of rigid control logic dispersed in a program source code. This article is concerned with the possible implementation of onboard intelligence. In contrast to the popular use of neural networks, the logic-based approach is based on clear and exact control rules with strict responsibility. Thus, formal specification and verification methods can be utilized. The article describes the Real-Time Control Algorithm Logic (RTCAL) for the above-mentioned purposes. We also present case studies of reasoning at the design and operation stages for providing the fault tolerant control of a spacecraft.

Multi-Criteria Clustering-based Recommendation using Mahalanobis distance
by Mohammed Wasid, Rashid Ali
Abstract: There have been significant advances made in the research of recommender systems over the past decades and have been implemented in both industry and academia. Recently, multi-criteria ratings are being incorporated into traditional recommender systems to further improve their quality, especially to handle the data sparsity and cold start issues. However, incorporation of multi-criteria ratings have improved the performance of the recommendation, but at the same time, multidimensionality issue is also arises. This paper presents a clustering based recommendation approach which is used for dealing with the multi-dimensionality issue in multi-criteria recommender systems. Here, we cluster the users based on their individual criteria ratings using K-means cluster-ing and the intra-cluster similarity is computed using Mahalanobis distance measure for neighborhood set gen-eration. This improves the recommendations quality and predictive accuracy of both traditional and clustering-based collaborative recommendations. The Yahoo! Movies dataset was used for testing the approach and the experiment conducted shows promising results.

Fast Algorithm of Image Enhancement based on Multi-Scale Retinex
by Alexander Zotin
Abstract: In this paper, a fast image enhancement algorithm based on Multi-Scale Retinex in HSV color model is presented. The proposed algorithm produces the result similar to the one which uses a nonlinear processing in the HSV color model, but with less computational cost. It uses linear dependencies of RGB colors from the V-component of HSV model. Additionally, to speed up the images processing and enhance the local contrast is suggested to perform Multi-Scale Retinex (MSR) computation only in the low-frequency area obtained by the wavelet transform. Experimental research was performed on more than 100 color images having non-uniform brightness. Different algorithms based on Retinex technology were implemented and their performance was compared. The proposed way of output image color formation allows to reduce processing time by 30-75%, depending on the image size. The experimental data show that the usage of the wavelet transform in proposed MSR algorithm additionally leads to 2-2.8 times increase in processing speed.
