    by Dhiman Banerjee, Sriparna Bhattacharya, Provas Kumar Roy 
    Abstract: Optimal power flow (OPF) problem plays a crucial role to run an economically efficient and well-planned power system. It is a strenuous and challenging task for the power system researchers to cope with the ever-increasing load-demand while getting the minimum system loss. The development of flexible ac transmission system (FACTS) has added a new dimension both to the system operation and research. Unified power flow controller (UPFC) is the most reliable FACTS controller, having its operational capability as series and shunt compensator. As a matter of fact, UPFC can reliably control the different power system parameters. In this article, UPFC is incorporated into the modified IEEE 5-bus and modified IEEE 30-bus test system. Differential search algorithm (DSA) is proposed and implemented to run the OPF with and without UPFC , and the results are listed, analyzed and compared with the same that is obtained by genetic algorithm (GA) and BAT search algorithm.

  • Development of Fuzzy Logic Controller for Improved Interline Unified Power Quality Conditioner   Order a copy of this article
    by Ravindranath Tagore Yadlapalli, Rajanand Patnaik Narasipuram, Anusha Dodda 
    Abstract: This paper presents the improved interline Unified Power Quality Conditioner (iUPQC) and its controlling aspects for nonlinear loads. The nonlinear loads are the major sources of harmonics and raise the power quality issues. However, the iUPQC compensates the harmonics that are generated by a nonlinear load besides reactive power support. This in turn minimizes the harmonic distortion both in the source current as well as voltage. Furthermore, it also provides the current and voltage imbalance compensations, reactive power, frequency and voltage support at grid. The simulation of entire power system is fulfilled using proposed FUZZY controller and compared with the conventional PI controller. The performance of both the controllers is sifted in terms of %Total Harmonic Distortion (THD) by considering different case studies having the 3-ϕ diode rectifier connected to R, RL & RLE loads. The MATLAB/Simulink version R2012b is used for accomplishing the in depth simulation studies.

  • New stochastic synchronization condition of neutral-type Markovian chaotic neural networks under impulsive perturbations   Order a copy of this article
    by Cheng-De Zheng 
    Abstract: This paper investigates the globally stochastic synchronization problem for a class of neutral-type chaotic neural networks with Markovian jumping parameters under impulsive perturbations in mean square. By virtue of drive-response concept and time-delay feedback control techniques, by using the Lyapunov functional method, vector Wirtinger-type inequality, a novel reciprocal convex lemma and the free-weight matrix method, a novel sufficient condition is derived to ensure the asymptotic synchronization of two identical Markovian jumping chaotic delayed neural networks with impulsive perturbation. The proposed results, which do not require the differentiability and monotonicity of the activation functions, can be easily checked via Matlab software. Finally, a numerical example with their simulations is provided to illustrate the effectiveness of the presented synchronization scheme.

  • The Multi-Object Tracking Algorithm Research using Kalman Filtering Method   Order a copy of this article
    by Shuqing Liu 
    Abstract: Aiming at the tracking failure caused by occlusion between objects, interleaving or target drift in multi-object tracking process, the new improved algorithm of occlusion prediction tracking based on Kalman filtering and spatiograms was proposed. By combining the color histogram and the distribution of color in space, spatiograms can be used to distinguish between different objects so that we can track the object when interleaving or occlusion between objects occurs. The state of the object can be predicted by the Kalman filtering, and the occlusion mark is used for the object which overlaps with other objects, so that the occluded object which is undetected can be tracked in the next frame video. The 2D MOT 2015 dataset was used in the experimental procedure, and the average accuracy of tracking was 34.1%. The experimental results have shown that the proposed algorithm can improve the performance of multi-object tracking process.

    Abstract: Clustering is one of the important functions of data mining, which is used to analyse a large amount of data. It groups these set of data according to some similarity property such that data within the cluster are similar to each other and data between the clusters are dissimilar to each other.

To encounter the above problem, optimization algorithms such as metaheuristic algorithms are used as a suitable problem-solving paradigm. This paper presents an overview of single-objective metaheuristic algorithms used for partitional clustering problem and their applications. This paper even presents the research issues which can be dealt with in future.

  • A new artificial bee colony based on neighborhood selection   Order a copy of this article
    by Xiaoyan Xiong, Jun Tang 
    Abstract: In this paper, we present a new artificial bee colony (ABC) for solving numerical optimization problems. In the original ABC, a new candidate solution is generated based on the current solution and a randomly selected one. However, the random selection method is unstable. To accelerate the search, a new neighborhood selection is proposed. For each current solution, we firstly randomly select some solutions from the current population. Then, we choose the best one among those solutions as the neighborhood solution to generate new solutions. To verify the performance, we test several classical numerical optimization problems. Simulation results show that our approach outperforms the original ABC and some improved ABC versions.

    Abstract: We propose the one-dimensional deep learning firefly algorithm guided by the best particle in order to increase the convergence speed and optimization precision of the firefly algorithm. In each generation of optimization process, the optimal particle is first updated in a fixed number of times according to the newly designed update formula. The update mode is defined as single-dimensional deep learning. After the optimal particle completes single-dimensional deep learning, other fireflies in the population keep the original evolutionary way to update the location and iteratively complete the optimization task. Experiments with 12 benchmark functions show that the proposed algorithm has a higher optimization capacity than the other six modified firefly algorithms.

  • Gaussian bare-bones firefly algorithm   Order a copy of this article
    by Hu Peng, Shunxu Peng 
    Abstract: Firefly algorithm (FA), as a relatively recent emerged swarm intelligence algorithm, is powerful and popular for the complex real parameter global optimization. However, the premature convergence has greatly affected the performance of original FA. To overcome this problem, we proposed a Gaussian bare-bones FA, named GBFA, in which each firefly moves to a Gaussian bare-bones method generated learning object rather than its better neighbors. The experiments are conducted on a set of widely used benchmark functions. Experimental results and comparison with the state-of-the-art FA variants have proved that the proposed algorithm is promising.

  • A hybrid binary harmony search algorithm for solving the winner determination problem   Order a copy of this article
    by Geng Lin, Zuoyong Li 
    Abstract: The winner determination problem (WDP) in combinatorial auctions is to determine an allocation of items to bidders such that each item is allocated to at most one bidder, and the auctioneer's revenue is maximized. This paper proposes a hybrid binary harmony search algorithm for the WDP. Firstly, to enhance the global search ability of the proposed algorithm, a modified harmony improvisation mechanism is developed with a modified memory consideration rule and an adaptive pitch adjustment scheme. Next, a repair operator is employed to guarantee the feasibility of the new candidate harmonies. Finally, a tabu search procedure is presented to improve the local search ability. These strategies make a good balance between intensification and diversification. In the experiments, the performance of the proposed algorithm is validated on five groups of 500 instances. Experimental results and comparisons show that the proposed algorithm is very efficient, and the tabu search procedure significantly improves the performance of the proposed algorithm.

  • Dynamic HypE for solving single objective optimization problems   Order a copy of this article
    by Qing Zhang, Sanyou Zeng 
    Abstract: One difficulty in solving optimization problems is the handling many local optima. The usual approaches to handle the difficulty are to introduce the niche-count into evolutionary algorithms (EAs) to increase population diversity. In this paper, we introduce the niche-count into the problems, not into the EAs. We construct a dynamic multi-objective optimization problem (DMOP) for the single optimization problem (SOP) and ensure both the DMOP and the SOP are equivalent to each other. The DMOP has two objectives: the original objective and a niche-count objective. The second objective aims to maintain the population diversity for handling the local optima difficulty during the search process. A dynamic version of a multi-objective evolutionary algorithm (DMOEA), specifically, HypE-DE, is used to solve the DMOP; consequently the SOP is solved. Experimental results show that the performance of the proposed method is significantly better than the state-of-the-art competitors on a set of test problems.

  • An Out-of-Band Mobile Authenticating Mechanism for Controlling Access to data outsourced in the Mobile cloud environment   Order a copy of this article
    by Sumit Kumar Yadav, Nisha Saroha, Kavita Sharma 
    Abstract: Mobile Cloud Computing (MCC), a cloud environment, formed by mobile users at the client-side and cloud servers at the back-end enables users to store and pervasively access a huge amount of data via different mobile devices (smartphones, tablets, PDAs, etc.) in a distributive manner. The "mobile cloud", though meant to resolve the space and processing constraints of mobile devices, increases the risk of data abuse, since data is outsourced on the distrusted cloud servers. Hence, to ensure the security of user's data, of all the security principles (confidentiality, integrity and access control) we argue that controlling access of data with appropriate authentication methods can strive for data protection and integrity. The drawbacks of the current frameworks, such as overloaded computations in key distribution, reduced flexibility, and scalability, are unable to achieve fine-graininess and confidentiality. Moreover, some are not even compatible with MCC environment due to their static nature. Thus, we propose an access control mechanism which is lightweight with minimal computational overhead and provides fine-grained access control for sharing data using out-of-band (OOB) mobile authentication. In this, we perform client-side encryption and decryption using simple hash functions and concatenation operator and achieve dynamic scalability. The encryption algorithms, sharing mechanism, and the use of OOB (out-of-band) mobile authentication are extensively analyzed to prove its efficiency and applicability.

  • Parkinsons Diagnosis Using Ant-Lion Optimization Algorithm   Order a copy of this article
    by Prerna Sharma, Rishabh Jain, Moolchand Sharma, Deepak Gupta 
    Abstract: Parkinsons disease (PD) is a long term progressive disorder of the central nervous system that mainly affects the movement of the body. But there are several limitations in detecting PD at an early stage. In this paper, a binary variant of the recently proposed Ant Lion Optimization (ALO) algorithm has been proposed and implemented for diagnosing patients for Parkinsons disease at early stages. ALO is a recently proposed bio-inspired algorithm, which imitates the hunting patterns of ant-lions or doodlebugs. The proposed algorithm is used to find a minimum number of features that result in higher accuracy using machine learning classifiers. The proposed modified version of ALO extracts the optimal features for the two different Parkinsons Datasets with improved accuracy and computational time. The maximum accuracy achieved by the classifiers after optimal feature selection is 95.91%. The proposed algorithm results have been compared with other related algorithms for the same datasets.

  • An Improved Chaotic-Based African Buffalo Optimization Algorithm   Order a copy of this article
    by Chinwe Peace IGIRI, Yudhveer Singh, Ramesh Chandra Poonia 
    Abstract: Optimization remains inevitable in any organization as the need to maximize the limited resources persists. It justifies the seemingly endless research in this area. This study explores the effectiveness of chaos to mitigate false or premature convergence problem in African Buffalo Optimization (ABO) algorithm. Chaos employs the ergodic and stochastic properties to handle this limitation. Three resourceful chaotic functions in the literature are evaluated to find the best strategy for ABO improvement. The same strategy is applied across the algorithms under study to provide an unbiased judgment. The study validates the proposed systems performance with a range of nonlinear test functions. The proposed systems result is compared with standard ABO, Particle Swarm Optimization (PSO), and chaotic Particle Swarm Optimization (CPSO) algorithms. Although chaotic ABO (CABO) gave 92% performance in comparison with standard ABO, chaotic PSO, and standard PSO; it requires further investigation. To be more explicit, the reason for no significant difference between chaotic-ABO and standard ABO in some functions calls for further research attention. The present study also highlights the research future scope. In all, the study gives insight to researchers on the appropriate algorithm for a real-world problem.

  • Image Integrity Verification via Reversible Predictive Hiding and Elliptic Curve Diffie-Hellman   Order a copy of this article
    by Siddharth Agarwal, J. Jennifer Ranjani 
    Abstract: This paper presents a medical image integrity verification algorithm which will be able to detect any changes made in the pixel value or the size of a medical image. At the same time, it also provides a secure way of transmitting images over the public domain. This algorithm can not only ensure integrity of the medical image, but also checks if the sender of the image is authentic, making it useful for archiving medical images and remote medical diagnosis. This algorithm essentially has three modules: hashing, data embedding and image encryption. Initially, hash signatures are extracted from the image and are embedded inside the medical image. In the embedding phase, the image is divided into blocks of uneven size. In the raster scanning order, the blocks are embedded with multiple pixels depending on its smoothness. At the receiver end, the signatures are extracted and it can be used to verify the integrity of the medical images. The effectiveness of the embedding algorithm is verified in terms of peak signal to noise ratio, structural similarity index metrics, correlation coefficient. $L^2-$norm is used for verifying the integrity of the images.

    by Shefali Arora, M.P.S. Bhatia 
    Abstract: Face authentication has become widespread on smart devices and in various applications these days. Real time detection of human faces in video surveillance systems is challenging due to variations in expression and background conditions. Thus, precise detection of spoofed faces is important to make such security systems robust against potential attacks. Several deep learning based techniques involving the use of Convolutional Neural Networks have proven to be excellent in detection of spoofed faces. In this paper, we have proposed the combined use of spatial and temporal information from facial images using CNN and Long Short Term Memory Networks. We have tested the approach on Idiap Replay-Attack benchmark and compared the results with the application of pre-trained models like InceptionV3, VGGNet and ResNet models to detect replay attacks during video surveillance. Our approach proves to be robust and more efficient for detection of security breaches in real time situations.

  • Increased PSNR with Improved DWT Digital Watermarking Technique   Order a copy of this article
    by IIfra I. Khan, Khaleel Ahmad, M.A. Rizvi, Khairol Amali Bin Ahmad 
    Abstract: Today, the world is moving towards a digital era in every walk of life. Every business unit, government and private sectors, and research organization use the digital image, as a transferring mode for every critical data. These images over the Internet are not secure. Therefore, there is a need for image security. Currently, various image security techniques like encryption, watermarking, steganography, etc. are being used. In this work, a new technique of image security is proposed using digital watermarking which is more efficient and robust than the existing technique of Discrete Wavelet Transformation (DWT). Use of DWT along with the Least Significant Bit (LSB) technique in the watermarking mechanism is intended to make the technique more efficient. The technique is tested against the PSNR of several images. The average PSNR calculated of all the tested images was compared to other techniques and found that the new technique is better than the existing techniques. This new technique is a novel technique which is highly robust and provides better and faster results. The main component is the transformation of a single image into an invisible watermarked image. The whole mechanism is greatly reliable on the Human Visual System, as the watermark is not visible to the human eye. This increases the security of the hidden image or messages. This technique can be used for security of multimedia data over the Internet.

  • Secure Provenance based Communication using Visual Encryption   Order a copy of this article
    by Kukatlapalli Kumar, Ravindranath Cherukuri 
    Abstract: Explicit specification of the historical record of an instance or a data item is called data provenance. It has many applications in various fields with regards to its importance on capturing data flow mechanisms. However, on the other hand, there are good number of security mechanisms in place to withstand the cyber-attacks. Almost all of these algorithms uses complex mathematical calculations in providing security for the systems. Visual cryptography is a peculiar approach which uses concept of secret sharing by dividing the message into transparencies as encryption process. Upon superimposing transparencies one obtains the original message. In this paper, we propose secret sharing as a notion of security onto data provenance. Main inference of this writing is to throw a model combining above two mentioned aspects which gives away an indigenous solution in the area of information security. This proposed model is implemented with specific use case scenarios for substantiation and related analysis. Simulated results and discussion of the same is presented in the paper.

    by Cao Honghua, Yan Xiaoyan, Li Yan 
    Abstract: In order to improve the performance of traditional fingerprint detection method in the process of tracking the shared bicycle, the inertial sensor is used for data measurement. The particle filter (PF) method is a widely used sensor fusion al-gorithm, but the initialization and weighting processes are problematic in shared bicycle positioning systems. In this paper, a new PF scheme is proposed, and it can produces smooth and stable localized knowledge. However, the feed-forward network that uses the single hidden layer is used to simulate the estimation and improvement of the performance of multiple probability to achieve the distinc-tion of similar fingerprints. At the same time, the random sample consensus al-gorithm (RANSAC) is used to initialize the algorithm so as to reduce the conver-gence time. Experiments show that the tracking error of this scheme is less than 1.2m, which is superior to the selected comparison method.

Then, the Markov approximate model is used to find a subop-timal solution, and further obtain the low delay data aggregation tree. Finally, the effectiveness of the MLDGT algorithm is analyzed by simulation and compari-son. The experimental results show that the MLDGT algorithm can reduce the data aggregation delay.

  • Energy Sensing Streaming Media Data Transmission Protocol Based on Implicit Markov Algorithm in WSNs   Order a copy of this article
    by Guozhong Li 
    Abstract: Streaming media transmission protocols can be divided into traditional streaming media push protocol and streaming media pull protocol. Traditional streaming media push protocols such as RTP, whose server determines the channel state according to the RTP feedback from the client, and then decides to send data packets suitable for the current channel state. The pull protocol of streaming media sends data packets according to the content of the client when the transmission rate meets the requirement on the contrary. Streaming media pull protocol greatly reduces the complexity of servers in streaming media transmission technology, it can also support the application of different adaptive algorithms in the transmission process compared with the traditional universal server transmission algorithm mechanism. Therefore, this kind of pull protocol cannot only improve the quality of service of streaming media transmission, but also meet the requirements of different channel states and different clients.

    Abstract: This thesis focuses on network equipments in the data center which hasrncaused rapidly growth of energy consumption recent years. The switches account for the largest proportion of energy consumption of network equipments, so turning off unneeded switches can reduce energy consumption effectively. Based on this point, we develop an high-efficient routing algorithm based on genetic algorithm(GA) in order to improve energy consumption of network equipments. Genetic algorithm is a kind of a heuristic algorithm which solves the optimization problem rapidly by imitating the way of the natural selection, but to a certain degree, it reduces accuracy. Its a complicated problem to decide routing path in arnshort period, so we choose genetic algorithm to achieve our goals. In ourrnsimulation, we make some improvements of GA in order to fit our problem andrnraise the accuracy of its solution.

  • On-Demand Distance Vector Refinement-Based Car Networking Stable Routing   Order a copy of this article
    by Shutao Zhou, Chengxing Li, Hui Yu 
    Abstract: Due to the high-speed movement of vehicles and obstacles in urban scenes, the communication paths between vehicles become extremely fragile. Specific to the routing problem of VANETs, a path criterion-based on-demand distance vector PA-AODV routing algorithm is proposed. The PA-AODV routing algorithm makes full use of the characteristics of AODV routing, and improves its routing decision. By calculating the path criterion weight and preferentially selecting the path with small weight for data transmission, the path stability is thus improved. The experimental data show that the proposed PA-AODV routing reduces the data packets loss rate and also shortens the end-to-end transmission delay.

  • Study on oceanic big data clustering based on incremental K-means algorithm   Order a copy of this article
    by Yongyi Li, Zhongqiang Yang, Kaixu Han 
    Abstract: With the increase of marine industry in the Beibu Gulf, data clustering has become an important task of intelligent ocean. Partition clustering methods are suitable for marine data. However, traditional K-means algorithm is not suitable for large scale data. Focusing on the characteristics of oceanic big data, we propose a clustering method based on incremental K-means (IKM) algorithm. First, a vector model is adopted to represent data sets, and the calculation model for mean values and centers is used to initialize arbitrary numbers of data points. Second, the input data vectors are iteratively calculated in an incremental vector form. Finally, by applying incremental vector and distance model, the large-scale data are clustered according to convergence condition. Experiments show that the algorithm can increase the clustering efficiency, reduce time and space complexity, and lower the missing data rate.

    Abstract: As one of the basic social relationships in current world, the relationship between the police and citizens directly reflects the relationship between the authority and the public, which play an important role in the social stability. It has an essential significance to properly get to know, to deal with and to evaluate the police-citizen relationship. Firstly, we design a hierarchy evaluation index system model about the harmony degree between the police and the citizens, with the help of questionnaires, based on the principle of designing an evaluation index system and the five major factors that impact the harmony relationship between the police and the citizens. Secondly, we set up a fuzzy comprehensive evaluation model based on an improved analysis hierarchy process (AHP). And then we make an empirical research on the harmony degree between the police and the citizens with the help of the model we set up. Finally, based on the conclusion of the empirical research, we make a propose to the government and the security department about how to promote the construction of the harmony police-citizen relationship. The research enriches the methods and means of evaluation the harmony degree of the police and the citizens and exemplifies the empirical research.
