  • Solving Quadratic Assignment Problem by Symbiotic Organisms Search Algorithm   Order a copy of this article
    by Heba Rashad, Abdel Nasser H. Zaied, Yongquan Zhou 
    Abstract: Symbiotic Organisms Search algorithm (SOS) is a new meta-heuristic algorithm based on the symbiotic relationship between the biological, which was proposed in recent years. In this paper, we propose new robust and powerful metaheuristic algorithm called an improved version of symbiotic organisms search algorithm integrated with construction algorithm and mutation operators (ISOS) to solve quadratic assignment problems. The Quadratic Assignment Problem (QAP) considers NP-hard combinatorial optimization problem and has various practical applications. A set of benchmarks from QAPLIB Library are employed to evaluate the performance of proposed algorithm. ISOS is compared to several algorithms in the literature. The comparisons show that the proposed algorithm shows reliable, efficient and promising results.

  • Gandhian management perspective for enhancing productivity and innovation in Public Sector Organization.   Order a copy of this article
    by Shashi Kant, Pramod Chandra, Vinay Sharma, Rajat Agrawal 
    Abstract: This paper underpins the importance of establishing Public Sector Undertakings (PSU) in India with special reference to one of the key industrial organizations, Bharat Heavy Electricals Ltd (BHEL), which focuses on elements of innovation that drives productivity inculcating the Gandhian management perspective. In the present competitive world, BHEL and other industrial PSUs are passing through a transitional phase of enhancing their productive competitiveness through both process and product innovation for sustainable growth. This requires introduction and adaption of non-conventional or modern modes of management based on the principles of Mahatma Gandhi. The need, importance and implication of Gandhian perspective in industrial organization got reemphasize. Mahatma Gandhis fundamental philosophical approach might not be radically different from that of others but it exists in the form of an approach that structurally recommends a pathway of wealth generation, productivity, wealth distribution, and economic prosperity for all. The paper intends to find traces of Gandhian management perspective in Indian PSUs and also tries to elicit relevant Gandhian elements of industrial organization management.
    Keywords: Public sector undertaking; ethical management; sustainable leadership; Gandhian management perspective; Gandhian innovation.

  • Performance study of Routing Protocols based on node mobility in MANETs   Order a copy of this article
    by Younes BEN CHIGRA, Abderahim GHADI, Mohamed BOUHORMA 
    Abstract: Mobile Ad Hoc network (MANET) is established by a set of smart mobile nodes without any central intelligence. Hence, nodes auto-discover their surrounding and establish needed links between source and destination node. Moreover, mobile nodes change arbitrary their position, which lead to frequent link failure. Therefore, the dynamic behaviour of nodes has a drastic impact on networks performances such as end-to-end delay, packet loss ratio and traffic control that is generated during route update process. Consequently, the main issue in MANETs operations is the design of an efficient routing protocol able to deliver required quality of service in case of nodes mobility and manage the intrinsic limitation of wireless networks, like scares bandwidth, limited energy and processing capabilities. The purpose of this paper is to study the impact of nodes mobility on routing performances and look forward an appropriate optimisation that might enhance efficiency of routing protocol in high dynamic environment.

  • A memetic algorithm for fleet size and mix vehicle routing problems with electric modular vehicles   Order a copy of this article
    by Dhekra Rezgui, Jouhaina Chaouachi Siala, Wassila Aggoune-Mtalaa, Hend Bouziri 
    Abstract: This work deals with an extension of the well-known Vehicle RoutingrnProblem with Time Windows (VRPTW), where the fleet consists of electric modular vehicles (EMVs). The main drawback of managing electric vehicles isrnthat they have a limited range. Here the vehicles are modular which means that payload modules are carried by a cabin module and can be detached at certain customer locations allowing the rest of the vehicle to continue the tour. This can also permit to recharge the battery of some modules to further capitalize on the gained energy. To tackle the resulting research problem, a comprehensive mathematical formulation is proposed to take into account the multiple constraints linked with the modularity, the electric charging, time windows to serve the customers and capacity issues. Due to the NP-hardness of the problem, a memetic algorithm is implemented and tested for designing good quality solutions in reasonable computational times. Extensive computational experiments carried out on some benchmark instances show the effectiveness of both the problem formulation and the memetic algorithm.

  • Architecture of a Decision Support System Based on Big Data for Monitoring Type 2 Diabetics   Order a copy of this article
    by Boudhir Anouar Abdelhakim, Ben Ahmed Mohammed, Fellaji Soumaya 
    Abstract: Type 2 diabetes is one of chronic diseases that require continuous and real-time monitoring to prevent the occurrence of complications. On the one hand, the doctor must have information about the patient's daily life (vital signs, stress, sedentary lifestyle, physical activities, nutrition, etc.). On the other hand, the prescribed treatment must be evaluated each time to test the validity of the diagnosis. To achieve this goal, a decision support system based on the Big Data Mining technology must be designed in order to have a centralized knowledge of diabetics. This system will improve the quality of monitoring and treatment from the different data collected. Thus, this paper presents an architecture of a decision support system allowing doctors to monitor the health status of their patients, based on data collected from different resources, in order to enrich the knowledge database and prescribe new treatments based on similar cases and experiences of doctors and patients belonging to this system.

  • MultiPrime Cloud-RSA: A Fast Homomorphic Encryption Scheme for Data Confidentiality Protection in Clouds   Order a copy of this article
    by Khalid EL MAKKAOUI, Abderrahim Beni-Hssane, Abdellah Ezzati 
    Abstract: Concerns over data confidentiality are amongst the main barriersrnlimiting the widespread adoption of cloud solutions. Indeed, scientists haverninvented a new promising form of encryption, homomorphic encryption (HE),rnwhich can be considered as a powerful tool to get over these concerns. Sincerncloud environments are more vulnerable to attacks and since cloud consumersrnfrequently access to cloud computing services using light-weight devices, the HE schemes must be promoted, in terms of security level and running time, to operate efficiently. In El Makkaoui et al. (2017), we boosted the normal RSA cryptosystem at security level, Cloud-RSA. In this paper, we suggest a new fast variant of the Cloud-RSA scheme, MultiPime Cloud-RSA, to accelerate its decryption process. The variant uses a modulus of the form n = p1p2...pk for k>= 2 and employs the Chinese remaindering to decrypt. Theoretical and simulation results show that the new variant offers a large decryption speed-up over the Cloud-RSA scheme whilst maintaining a recommended security level.

  • Fuzzy Association Rule Mining for Economic Development Indicators   Order a copy of this article
    by Deepesh Kumar Srivastava, Basav Roychoudhury, Harsh Vardhan Samalia 
    Abstract: This paper is focused on fuzzy mining approach to extract fuzzy association rules among the economic development indicators that are Net official development assistance received (ODA), foreign direct investment (FDI) and gross domestic product (GDP) for developing country India.This study is an attempt to explore the use of fuzzy association rule mining on time series data and to extract interesting association rules therefrom. The extracted rules exhibit the relative volatile nature of these three development indicators. A fuzzy membership function is used to transform the quantitative values of percentage change of each successive year datum into fuzzy sets in linguistic terms. The scalar cardinality of each linguistic term is calculated on the yearly data. Only those fuzzy association rules that qualified the criteria of minimum support and minimum confidence value were taken into consideration. The rules thus mined out exhibit quantitative regularities and can be used for the better suggestion to appropriate policy makers.

  • High Performance Inventive System for Gait Automation and Detection of Physically Disabled Persons   Order a copy of this article
    by Vinothkanna Rajendran, Vijayakumar Thangavel, Prabakaran Narayanasamy 
    Abstract: Physically challenged persons may face many difficulties in the present modern environment as most of the commercial facilities and utilities for a day to day life is designed for normal people to lead a sophisticated life. Particularly people physically disabled face struggles in escalators in malls and public transportation places. It is very difficult for the disabled individual to be identified as one among in a large crowd and they normally feel unconformable to step inside in a running escalator. This research work proposes a novel method to identify the physically challenged persons from a large crowd by their nature of legs, walking pattern and hand sticks and provide necessary preference for them to get inside the escalators. Gait automation and detection mechanism is used for person identification for all gait events and deep learning based neural network (DLNN) is used for learning the patterns and making the system to automatically identify the physically challenged. Experimental results shows that the proposed system automatically measures all the angle of gait events with an accuracy level of 95.4% and thus offers a cost effective solution for gait kinematic analysis for disabled peoples.

  • Comparative Study on IDS using Machine learning approaches for Software Defined Networks   Order a copy of this article
    by Muthamil Sudar K, Deepalakshmi P 
    Abstract: Software Define Networking (SDN) is an emerging network approach that separates the data plane from control plane and enables programmable features to efficiently handle the network configuration in order to improve network performance and monitoring. Since SDN contains the logically centralized controller which controls the entire network, the attacker mainly focuses on causing vulnerability towards the controller. Hence there is a need of powerful tool called Intrusion Detection System (IDS) to detect and prevent the network from various intrusions. Therefore, incorporation of IDS into SDN architecture is essential one. Now a day, Machine Learning (ML) approaches can provide promising solution for the prediction of attacks with more accuracy and with low error rate. In this paper, we surveyed about some machine learning techniques such as Naive Bayes, Decision tree, Random forest, Multilayer Perceptron algorithms for IDS and compare their performance in terms of attack prediction accuracy and error rate. Additionally, we also discussed about the background of SDN, security issues in SDN, overview of IDS types and various machine learning approaches with the knowledge of datasets.

    by Balamurugan S.P., G. Arumugam 
    Abstract: The main aim of this research is to design and develop an efficient approach for predicting ultrasound kidney diseases using multiple stages. Nowadays, kidney disease prediction is one of the crucial procedures in surgical and treatment planning for ultrasound images. Therefore, in this paper, we propose a novel ultrasound kidney diseases prediction using the artificial neural network (ANN). To achieve the concept, we comprise the proposed system into four modules such as preprocessing, feature extraction, feature selection using OGOA and disease prediction using ANN. Initially, we eliminate the noise present in the input image using the optimal wavelet and bilateral filter. Then, a set of GLCM features are extracted from each input image and then we select the important features using oppositional grasshopper optimization algorithm (OGOA). To classify the image as normal or abnormal, the proposed method utilize an artificial neural network (ANN). The performance of the proposed method is evaluated using accuracy, sensitivity, and specificity. The experimentation results show that the proposed system attains the maximum accuracy of 95.83% which is high compared to existing methods.

  • Recurrent Neural Network based Speech Recognition using MATLAB   Order a copy of this article
    by Praveen James, Mun Hou Kit, Chockalingam Aravind Vaithilingam, Alan Tan Wee Chiat 
    Abstract: The purpose of this paper is to design an efficient Recurrent Neural Network (RNN) based speech recognition system using software with Long Short-Term Memory (LSTM). The design process involves the implementation of speech acquisition, pre-processing, feature extraction, training and pattern recognition tasks for a small vocabulary sentence recognition system using RNN. A vocabulary of 80 words which constitute 20 sentences is used to train and test a vanilla LSTM network. The depth of the layer is chosen as 20, 42 and 60 and the accuracy of each system is determined. The results reveal that the maximum accuracy of 89% is achieved when the depth of the hidden layer is 42. Design complexity and processing time are considered when the signal acquisition, pre-processing, feature extraction, and training algorithm are implemented. In this paper, there are 5 layers namely, the input layer, the fully connected layer, the SoftMax layer, the output layer and one hidden LSTM layer that can be increased for more complex design requirements. The LSTM network stores previous values and is the core component of the speech recognition system. Since the depth of the hidden layer is fixed for a task, increased performance can be achieved by increasing the number of hidden layers. However, the processing time increases as the number of layers increase which necessitates a dedicated hardware device.

  • S-Transform Based Efficient Copy Move Forgery Detection Technique in Digital Images   Order a copy of this article
    by Rajeev Rajkumar, Sudipta Roy, Manglem Singh 
    Abstract: Copy-move Forgery (CMF), which copies a part of a picture and pastes it into another location, is one of the common strategies for digital image tampering. Due to the arrival of high-performance hardware and the compact use of image processing software, empowers creating image forgeries easy that are undetectable by the naked eye. For CMF detection, we suggest an efficient and vigorous method that could take care of numerous geometric ameliorations including rotation, scaling, and blurring. In the projected CMF detection system, we use Stock Well Transform (S-Transform) which hybrids the advantages of both Scale Invariant Feature Transform (SIFT) and Wavelet Transform (WT) to extract the key points and their descriptors from the overlapped image blocks. Furthermore, Euclidean distance (ED) between the overlapped blocks are measured to detect the similarities and to identify the tampered or forged region in the image. Besides, a novel Fuzzy min max Neural Network based Decision Tree (FMMNN-DT) classifier is used to recognize the duplicated regions in the forgery image. The proposed system is tested and validated using MICC-F220 dataset and we present comparison among the proposed outcomes with some existing ones which ensure the significance of the proposed.

    Abstract: Bioinformatics is an active research area which combines biological matter as well as computer science research. The longest common subsequence (LCS) is one of the indispensable issue to be unraveled viably in computational science. Discovering LCS is fundamental undertaking in Deoxyribonucleic Acid (DNA) arrangement investigation and other molecular biology. In this paper, new calculation for discovering LCS of two DNA successions and its area is proposed. The objective of this created framework is to discover the area and length of all subsequences which introduces in the two arrangements. To achieve this, DNA sequences are stored in an array and the comparison of DNA sequences are performed using matching algorithm. At the end of matching process, group of subsequence are obtained. Then the length and location of the matched subsequence are computed. After completing the matching process, longest common subsequence(s) is located. In this proposed work, maximally obtained length of LCS is 8. Finally, the computation time is calculated for locating LCS in DNA sequences. In addition to this, computation time is analyzed by gradually increasing the length (in characters count) of DNA sequences from 100, 200, 300, 400 and 500. It concludes that computation time for locating LCS in various lengths of DNA sequences took few seconds difference only.

  • Rapid Retrieval of Secured Data from the Sensor Cloud using a Relative Record Index and Energy Management of Sensors   Order a copy of this article
    by Geetha S, Deepalakshmi P 
    Abstract: A massive amount of data is produced by sensors. The data eventually finds a place in the cloud through a base station. Occasionally, the data collection process is disrupted as a result of the energy level of the sensor network. The energy of sensor batteries can be drained by voids. Void sensors do not propagate messages intended for the destination. We have addressed the issue of voids in sensors with the Dynamic Void Removal Algorithm. Data stored in the cloud is being used and retrieved by multiple customers through specifying the relative record index of the sensor data collected. A security mechanism is built with the help of the relative record index associated with sensor data collection. Authenticated customers are given a secret key to rapidly retrieve data from the cloud. Meanwhile sensor networks require a secure mutual authentication scheme in an anxious network environment; we use the Relative Record Index method to design a new user authentication procedure. Our etiquette can handle all problems thrown up by the former schemes. Furthermore, it enhances Wireless Sensor Network authentication with a higher degree of security than other protocols. Therefore, our protocol is more suited to an open and higher-security Sensor Network environment despite greater computation cost and energy.
