Social Network Analysis: Friendship inferred by chosen courses, Commuting time and Student Performance at University
by Lionel Khalil, Marie Khair
Abstract: Our Social Network Analysis (SNA) evaluates the performance of students taking courses with a group of friends versus students used to take courses alone. We evaluate the probability to be friend by comparing the number of courses shared by students with the probability to be assigned in the same classroom randomly based on curriculum constraints. A minimum of courses taken in common is used as a criterion to identify students belonging to a tribe of friends. The main findings are that students in tribes over perform other students by about half point of GPA, and are dropping and repeating fewer courses. Considering student without friends, we measured the impact of the commuting distance on GPA and drop off rate: students with very low GPA and high drop off are mostly students with significant higher commuting time.

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 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.

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

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.

Energy Efficient Data Compression and Aggregation Technique for Wireless sensor Networks[TELSOB MOTES]
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.

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.

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 Lakshmanaprabu Sk
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.

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.

Still there is a need for developing low power, high accurate, more intelligent machine learning framework for embedded architectures when they are used for dynamic inputs in health care solutions. Hence we propose a framework named SIVA (Self Intelligent Versatile and Adaptive) for dynamic inputs in IOT based health care solutions. This framework is based on Neural Network and Cognitive rule sets for self learning and adaptability. The proposed learning algorithm works on self adaptive principles which make the framework suitable for the biomedical wearable devices for dynamic inputs. This framework has been evaluated for different biomedical sensors and embedded heterogeneous architectures. Various performance parameters viz. recognition rate, accuracy, execution time and energy are measured and analysed. The results indicate that the framework not only have superiority on complexity, but also have low power consumption over existing neural network and svm algorithms.

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.

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.

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 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 150ºC and it is only 0.430mW for the proposed MAC. The proposed MAC consumes 87.51% less power than the conventional MAC for the same set of simulation environment.

by Wei Song, Shiwei Zhang, Lizhen Liu, Hanshi Wang
Abstract: With the development of e-commerce sites, online reviews have become important data resources for e-customers. However, the quality of review varies a lot, with positive reviews always intermingled with negative ones, seriously interfering with their accuracy and credibility and making it very difficult for consumers to make the right purchase decision. Nowadays, there have been many literatures on the category of reviews category or ranking for public. The thing is, they only satisfy common preferences, and ignore personalized preferences of individual users. In view of this phenomenon, this paper is trying to put forward a ranking method for individual preferences. It begins with collecting the rules of user preferences by showing reviews to them to let them mark the reviews they like. Then it combines the common rules with user personalized rules to get the range of features. Finally, after calculating the optimal solution of features, the paper strives to structure a ranking model to rank reviews with the set of optimal solution.

by Tao Duan, Ang Wang
Abstract: It is well-known that the accuracy of classification prediction is relatively high, but the prediction result is obscure in concept since result is given in two-value form (0 or 1) which says that red tide exists or does not exist. On the other hand, the accuracy of numerical prediction is relatively low, but it can offer density value of plankton which influences red tide. In order to combine characteristics of the above mentioned two methods, a prediction method for red tide which is mixed with integration model of hierarchical agglomerative T-S fuzzy inference is proposed. In the Thesis, through using the proposed prediction method mixed with integration model of hierarchical agglomerative T-S fuzzy inference, taking respective advantages of classification prediction and numerical prediction in prediction process for reference, and through experiment and comparison, it is proved that this algorithm is better than LMBP algorithm in prediction accuracy which shows the validity of the proposed algorithm. In the next step, it is mainly to further study the practical application of the algorithm, and to apply this prediction model to red tide warning system, and also to conduct experimental verification for a certain period by using actual marine environment.

Key Data for Cloud Computing based on Ensemble Clustering Approximate Analysis
by Zou Yu, Qin Zhong Ping
Abstract: To realize multi-label classification of text and meanwhile reduce calculation complexity and keep classification precision, dimensionality-reduction clustering method for fuzzy association of text multi-label based on cluster classification has been proposed. In text classification, it usually involves enormous feature numbers, which may cause curse of dimensionality. In addition, classification region can not always keep convex characteristics. It can be non-convex region composed of several overlapping or intersecting sub-regions. Above mentioned automatic classification system may require enormous memory requirement or has poor classification performance. Hence, new multi-label text classification method is proposed to overcome these problems in combination with fuzzy association technology. Fuzzy association evaluation is adopted to transform high-dimension text to low-dimension fuzzy association vector, thus avoiding curse of dimensionality. Experiment results show that the proposed method can more effectively classify text multi-label problem.

Design of Unsupervised Facial Expression Animation Based on Geometric Grid Measurement
by Niu Chunzhou, Zhu Yukai
Abstract: Many actual application images in the real world are formed by high dimensional data in most cases, while the manifold learning algorithm can explore the nonlinear information hidden in these high dimensional data. As most of manifold learning algorithms can only be defined in training cluster, it is impossible to project the sample on the lower dimensional space. In the Thesis, we introduce a kind of double manifold algorithm based on LLE and Isomap. Different from the traditional LLE algorithm, our algorithm learns two kinds of manifold information in which one group of data relates to many types and it compares two kinds of single LLE algorithm and Isomap algorithm through the setting of the appropriate nearest neighbor number K. No matter for the recognition rate or running time, it is obviously superior to the other two kinds of algorithms and it can effectively achieve the estimation of facial expression and significantly reduce the computation complexity.

by Sun Shanhui, Li Hong, Li Zhuangzhuang, Zhang Bingqiu
Abstract: To study the diagnosis of hospitalized patients with neurosis and its influencing factors, this article, on the basis of the data of treating hospitalized patients with neurosis hospitalization, empirically analyzes the relationship between the treating effect and personal basic situation, personal social relations, personal original condition, and makes the corresponding regression analysis and factor analysis. The results show that the patient's social relationship and personal character are obviously related to the diagnosis of neurosis. There are obvious correlations between the original condition in the early diagnosis and patients with neurosis, so it is important to strengthen the understanding and analysis of the original condition. We should strengthen publicity and education of mental health knowledge, encourage people from all walks of life to actively participate in it and improve their awareness of neurosis, and thus to effectively reduce the bias in patients with neurosis. Untimely separation and unharmonious relation with parents are one of socio-psychological factors which cause adults suffer neurological disorders.

Multi Criteria Decision Making Method based on Analytic Hierarchy Process with Intuitionistic Fuzzy Preference Information
by Cai Liang
Abstract: An extension method of multi criteria decision making (MCDM) is proposed in the Thesis for selection and assessment of parting line in mold design. First of all, linguistic variable is used to express grade of alternative parting line scheme and weight of criterion significance; and then, the membership function of final fuzzy assessed value is determined based on these linguistic values; in the end, a new ordering method of maximum and minimum sets will be adopted for normalization of weight grading and defuzzification to clear value and for strength and weakness ordering of alternative scheme. The verification and contrast experiment show effectiveness of the method in the Thesis and the comparison with traditional fuzzy multi criteria decision making method shows the method in the Thesis is more applicable.

Abstract: Targeted at the wireless sensor network in heterogeneous distribution composed of solar energy supply nodes and zero energy supply nodes, the cluster routing algorithm based on node density and energy size is proposed. In this Thesis, the wireless sensor network of heterogeneous non-uniform distribution is studied, and sun energy harvesting model ISHE based on intensity of illumination is proposed. In IISHE model, at first, the light intensity sensor is used to read solar illuminance under the current environment, and then, energy size obtained by solar energy supply node at specified period can be estimated based on corresponding relation between illuminance and irradiance. The model is characteristic of strong timelines and high calculation accuracy.

by Xin Xiong, Li Kefeng
Abstract: Robust Principal Component Analysis (RPCA) and kernel sparse representation technology which have been proposed in recent years provide a new idea for solving problems of the above three aspects. In this Thesis, classification algorithm of kernel sparse representation has been proposed based on robust principal component analysis by using RPCA technology to generate redundant dictionary and kernel sparse representation to structure classifier, and has been used for face recognition. Basic idea of this algorithm is to generate base dictionary and error dictionary by using RPCA technology, and to realize face recognition through classifier structured by kernel sparse representation. Firstly, each training sample matrix has been decomposed into a low rank matrix and a sparse error matrix by using RPCA technology, so as to structure base dictionary and error dictionary by using the low rank matrix and error matrix respectively, and generate redundancy dictionary of sparse representation of test samples. Then, Kernel regularized Orthogonal Matching Pursuit (KROMP) algorithm has been proposed to get sparse representation coefficient which has been used to complete classification and recognition of test samples. Compared with similar algorithms, algorithm in the Thesis is of a high recognition rate for face recognition, and has a strong ability to adapt to noise and error interference.rnrn

An Arabic Natural Language Interface for Querying Relational Databases Based on Natural Language Processing and Graph Theory Methods
by Bais Hanane, Mustapha Machkour, Lahcen Koutti
Abstract: Nowadays, databases represent a great source of information. To extract information from these databases, the user needs to write queries using database query languages, such as Structured Query Language(SQL). Generally, for using this type of language, this user must know the structure of the database. However, this task can be difficult for non-expert users. In that, the using of natural language to extract data from the database can be a very important and efficient method. The problems in using natural language query are that it doesn't give any specification about the path access correspond to the required data. For that, many previous works are deal with the problems of freeing users from knowing the detailed structure of the database. But, Almost of this works are designed to the English language. Whereas, for the Arabic language which is the subject of this paper, there is not any proposed system. For that, we present in this paper a model of a natural language interface for databases. This interface allows the user to access data stored in the database by using Arabic language and it obviates the need for users to know the internal structure of the underlying databases. Also, it can function independently of database domain, and it can to improve its knowledge base through experience.
Keywords: Arabic language processing; DataBase; Graph theory; Dijkstra Algorithm; Extended Context Free Grammar.
Glossary Applications Model for Financial Terms with Boyer-Moore-Horspool Method Based on Mobile Application
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.
