  • Multi-Agent System Approach for Improve Real-Time Visual Summaries of Geographical Data Streams   Order a copy of this article
    by Zina Bouattou, Robert Laurini, Hafida Belbachir 
    Abstract: Interdisciplinary efforts are needed to support visual exploration and analysis of spatio-temporal data streams from sensor networks, depending on the size and complexity of data that must be analysed before being displayed. For this, several emerging approaches have been proposed known as Visual Summaries of a set of data that will help users find what is most important and interesting to visualize in the mass of available information. In this paper, we present an approach for generating automatically the visual summaries in real time. For this approach, we have adopted chorem-based visual representations of territories issued from both geometric and semantic generalizations. Roger Brunet defined Chorems as schematized visual representations of territories. Our approach relies on a multi-agent framework; an extraction knowledge agent is able to extract important spatiotemporal patterns of data streams coming from a sensor network as interesting regions, and a visualization agent which displays those patterns as simplified maps. The novelty is the multi-agent semantic generalization and its combination with cartographic generalization to generate maps on-the-fly. We validate this model with an example taken from the meteorology field.

  • Automatic Arabic Text Summarization System (AATSS) Based on Morphological Analysis   Order a copy of this article
    by Laiali Almazaydeh 
    Abstract: This Automatic text summarization is a challenging task. Existing techniques suffer from inadequate investigation for Arabic text. The majority of Arabic words are derived according to the morphology that is more complicated than English and other Natural languages. The approach reported in this paper elaborates a morphological analysis to develop a new Automatic Arabic text summarization. The proposed approach is based on three main phases: the text tokenization phase, the trilateral root extraction phase and the aggregate similarity computation phase. The proposed approach has been extensively experimented on samples from the benchmark datasets of EASC. Experimental results show the ability of the proposed system to extract relevant sentences that reflects the summary of Arabic text, as well as a comparable performance with other reported techniques in the literature.
    Keywords: Information retrieval; Arabic language; summarization; trilateral rootroot; aggregate similarity.

  • A Two-Phase Human Activity Classification Design Using Accelerometer Data from Smartphone   Order a copy of this article
    by Syed Arsalan Ali, Rooh Ul Amin 
    Abstract: This paper presents a two phase design for the classification of the human movement activities of Running, Walking and Standing by using accelerometer data logged from smart phone. The first phase of the design is, the two-stage filter applied for the process of raw acceleration data collected from the accelerometer; and the second phase of the design is, the classification of human movements using Logistic Regression with Gradient Descent Algorithm as classifier from the clean data produced by first phase of the design. The raw acceleration data from the tri-axial accelerometer of smart phone contains three axes accelerations. This acceleration data is collected separately for each movement activity and is used for the training and testing of design by using a simulation environment. The activity classification results are promising and show that the proposed design provides an accuracy of more than 96 percent on both train data and the separate independent test data for the classification of human movement activities of Running, Walking and Standing.

    by Suraiya Jabin, Niladri Chatterjee, Suos Samak, Kim Sokphyrum, Javier Sola 
    Abstract: The present paper describes design of an online hybrid Machine Translation (MT) system involving a low-resource language Khmer. A Statistical Machine Translation system is typically trained on a large parallel corpus in order to compute the translation probabilities, and on an even larger quantities of monolingual data to compute the target language n-gram probabilities that are used to design the language model. The proposed system uses the open source SMT toolkit DoMY CE for training corpus (English-Khmer parallel corpus and also developing the corpus) combined with a post processing step of using parts of speech tagger to further enhance the quality of target language sentence. Web technologies, such as, Python, Apache2 (Web server), HTML, XML, and XSLT for developing an online translation system. Language Model, Translation Model and Decoder Configurations are done in accordance with recent literature using the DOMY toolkit. The parallel corpora have been prepared from various sources, such as ICT books for high school students, translated texts from chemist, education glossaries, law and history articles, country and city names, and the Headley Khmer-English dictionary. Experimental results are presented to demonstrate the success of phrase based SMT methods where English has been used as source and Khmer, a low-resource language as a target language. We used NIST (National Institute of Standards and Technology) and BLEU (BiLingual Evaluation Understudy) metrics have been used evaluate the performance of the system based on the training corpus built. In our experiments the proposed model achieved significantly good BLEU and NIST scores. Khmer being the official language of Cambodia the demand for such an automated system has been on the rise for several decades. The present work is one of the useful efforts towards meeting this demand.

  • Robust Feature Selection Algorithm based on Transductive SVM Wrapper and Genetic Algorithm: Application on Computer-Aided Glaucoma Classification   Order a copy of this article
    by Nawel Zemmal, Mokhtar Sellami, Djamel Zenakhra, Nilanjan Dey, Amira S. Ashour 
    Abstract: Glaucoma has become a devastating disease after cataract to cause blindness. Thus, early diagnoses for glaucoma can prevent the vision loss. Computer Aided Diagnosis (CAD) systems, which automate the process of ocular disease detection, are urgently needed to alleviate the burden on the clinicians. In the current work, advanced machine learning algorithms are investigated to propose a robust system for Glaucoma diagnosis based on retinal images. Three features extraction methods, namely the Gray-Level Co-Occurrence Matrix (GLCM), Hu moments and Central moments are combined to form the entry feature vector. To select the most relevant features and taking into account at the same time the unlabeled data existing in medical databases, a new scheme of feature selection algorithm is proposed. It is based on Transductive SVM Wrapper and Genetic algorithm, which automatically detect and classify the glaucoma disease using fundus images. The effectiveness of the proposed GA-TSVM is evaluated on a public retinal database RIM-ONE using the classification accuracy, sensitivity, and specificity metrics. The experimental results established that with 16% of labeled data, the proposed system could easily distinguish between the normal and the affected glaucoma cases.

  • Enhanced Particle Swarm Optimization Algorithms for Multiple-Input Multiple-Output System Modelling using Convolved Gaussian Process Models   Order a copy of this article
    by Gang Cao, Edmund Lai, Fakhrul Alam 
    Abstract: Convolved Gaussian Process (CGP) is able to capture the correlations not only between inputs and outputs but also among the outputs. This allows a superior performance of using CGP than standard Gaussian Process (GP) in the modelling of Multiple-Input Multiple-Output (MIMO) systems when observations are missing for some of outputs. Similar to standard GP, a key issue of CGP is the learning of hyperparameters from a set of input-output observations. It typically performed by maximizing the Log-Likelihood (LL) function which leads to an unconstrained nonlinear and non-convex optimization problem. Algorithms such as Conjugate Gradient (CG) or Broyden-Fletcher-Goldfarb-Shanno (BFGS) are commonly used but they often get stuck in local optima, especially for CGP where there are more hyperparameters. In addition, the LL value is not a reliable indicator for judging the quality intermediate models in the optimization process. In this paper, we propose to use enhanced Particle Swarm Optimization (PSO) algorithms to solve this problem by minimizing the model output error instead. This optimization criterion enables the quality of intermediate solutions to be directly observable during the optimization process. Two enhancements to the standard PSO algorithm which make use of gradient information and the multi-start technique are proposed. Simulation results on the modelling of both linear and nonlinear systems demonstrate the effectiveness of minimizing the model output error to learn hyperparameters and the performance of using enhanced algorithms.
    Keywords: Enhanced PSO; Convolved Gaussian Process Models; Hyperparameters Learning.

    by Jiaming Li 
    Abstract: Various faults occurred in the Heating, Ventilation and Air-Conditioning (HVAC) systems usually lead to more energy consumption and worse thermal comfort inevitably. This paper presents a feasible and valid solution of HVAC fault detection and diagnosis problem based on statistical machine learning technology. It learns the consistent nature of different types of faults of HVAC operation based on Support Vector Machine (SVM), and then identify types of fault in all subsystems using the statistical relationships between groups of measurements. In order to speed up the learning process, Principle Component Analysis (PCA) has been applied to compress the training data. Our approach models the dynamical sub-systems and sequence data in HVAC system. The learnt models can then be used for automatic fault detection and diagnosis. The approach has been tested on commercial HVAC systems. It had successfully detected and identified a number of typical AHU faults.

  • Efficient Blind Nonparametric Dependent Signal Extraction Algorithm for Determined and Underdetermined Mixtures   Order a copy of this article
    by Fasong WANG 
    Abstract: Blind extraction or separation statistically independent source signals from linear mixtures have been well studied in the last two decades by searching for local extrema of certain objective functions, such as non-Gaussianity (NG) measure. Blind source extraction (BSE) algorithm for extracting statistically dependent source signals from underdetermined and determined linear mixtures is derived using nonparametric NG measure in this paper. After showing that maximization of the NG measure can also separate or extract the statistically weak dependent source signals, the nonparametric NG measure is defined by statistical distances between different distributions of separated signals based on cumulative density function (CDF) instead of traditional probability density function (PDF), which can be estimated by the quantiles and order statistics (OS) using the norm efficiently. The nonparametric NG measure is optimized by a deflation procedure to extract or separate the dependent source signals. Simulation results for synthesis and real world data show that the proposed nonparametric extraction algorithm can extract the desired dependent source signals and yield ideal performance.

  • Indic Script Identification from Handwritten Document Images   Order a copy of this article
    by Pawan Kumar Singh, Ram Sarkar, Mita Nasipuri 
    Abstract: Script identification plays an important role in document image processing especially for multilingual environment. This paper hires two conventional textural methods for the recognition of the scripts of the handwritten documents inscribed in different Indic scripts. The first method extracts the well-known Haralick features from Spatial Gray-Level Dependence Matrix (SGLDM) and the second method computes the fractal dimension by using Segmentation-Based Fractal Texture Analysis (SFTA). Finally, a 104-element feature vector is constructed from the features designed by these two methods. The proposed technique is then evaluated on a total dataset comprising of 360 handwritten document pages written in 12 Indian official scripts namely, Bangla, Devanagari, Gujarati, Gurumukhi, Kannada, Malayalam, Manipuri, Oriya, Tamil, Telugu, Urdu and Roman. Experimentations using multiple classifiers reveal that Multi Layer Perceptron (MLP) shows the highest identification accuracy of 96.94%. Encouraging outcome confirms the efficacy of customary textural features to handwritten Indic script identification.

  • Combining RSS-SVM with Genetic Algorithm for Arabic Opinions Analysis   Order a copy of this article
    by Amel ZIANI, Nabiha Azizi, Djamel Zenakhra, Soraya Cheriguene 
    Abstract: The Arabic language has drawn the attention of researchers in data mining due to its large-scale users, but it presents challenges because of its richness and complex morphology. That explains the growing importance of the Arabic sentiment analysis and precisely the Arabic opinion detection and classification areas. Thus, the most accurate classification technique used in this area which proven by several previous works is the Support Vector Machine classifier (SVM). This last, is able to increase the rates in opinion mining but with use of very small number of features. Hence, reducing features vector can alternate the system performance by deleting some pertinent ones. To overcome these two constraints (features vector size and considerate all extracted primitives), our idea is to use Random Sub Space algorithm (RSS) at first stage to generate several features vectors with limited size; and to replace the decision tree base classifier of RSS with more accurate classifier which is the SVM. Therefore, each one of the generated features subsets will be the entry of an individual SVM classifier. Despite the obtained high results of this proposed approach, another proposition was implemented in order to enhance the previous algorithm by using the genetic algorithm as subset features generator based on correlation criteria to eliminate the random choice used by RSS and to prevent the use of incoherent features subsets. For that, features extraction stage is considered the main step in opinion mining process. Wherefore, to extract and to calculate the best informative linguistic and statistic features, we struggled with the lack of labeled Arabic dataset. So, a translated SentiWordNet dataset has been used to overcome this problem and to ameliorate the proposed system performance. The experiments results applied on one thousand (1000) labeled reviews collected from Arabic Algerian newspapers and manually annotated are very promising.

    Abstract: The face is the first source of information that inspires the attractiveness of a human being, for this reason; several studies were conducted in the aesthetic medicine and the image processing to analyze the aesthetic quality of an adult human face. This paper proposes an automatic procedure for the analysis of facial beauty. First, we detect the face zone on an image and its features areas, then we present our novel method to extract features corners, and finally we analyze the facial aesthetic quality. Experimental results show that our method can extract the features corners accurately for the majority of faces presented in the ECVP and FEI images databases, and that there exist a difference in the facial beauty analysis by gender and age, due to anatomic differences in specific facial areas between the categories.

  • Enhancement based Background Separation Techniques for Fruit Grading and Sorting   Order a copy of this article
    by Jasmeen Gill 
    Abstract: Image processing plays a remarkable role in the automation of fruit grading and sorting. While grading the fruit, accurate extraction of fruit object from the image (background separation) is the chief concern. For extraction of fruit, appropriate segmentation technique is employed; and to accomplish it accurately, enhancement must be performed prior to segmentation. However, majority of the researchers emphasized over fruit segmentation alone. This communication is intended to show the potential of enhancement techniques when combined with fruit image segmentation. Besides, it presents a comparative analysis of enhancement based background separation techniques for fruit grading and sorting. For this purpose, four main techniques, namely, Contrast limited adaptive histogram equalization (CLAHE) method, Gaussian filter, Median filter and Wiener filter were utilized for enhancement and Basic Global thresholding, Adaptive thresholding, Otsu thresholding and Otsu-HSV thresholding were applied for segmentation. 16 sub-models were developed by combining each enhancement method with every segmentation technique. Afterwards, the image quality of the sub-models was validated using quantitative as well as qualitative analyses. Test results demonstrate that CLAHE/Otsu-HSV model outperformed the others for fruit grading and sorting.

    Abstract: Securing the medical images, to make it tamper free is a terribly difficult task. This challenge is with efficiency handled with the assistance, digital watermarking techniques. With the assistance of this growing technology we are able to evaluate validation, dependability, privacy and integrity of the medical images. Several algorithms are enforced on this technology. The Digital Watermarking (DWM) is implemented in two main domains: transform & spatial. The DWM is mostly implemented using the transform techniques such as Singular Valued Decomposition (SVD), Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), combination of DCT and DWT and also with the combination of DWT and SVD. These days the work is extended with Integer Wavelet Transform (IWT). One of the foremost challenges in these technologies is information embedding capability or we say; number of bits hidden in the cover information. This parameter is considered for evaluation of the system since as we know that the more number of bits; the distortion of the medical information is also more and vice versa. The distortion of the information is strictly avoided within the case of medical and military applications. To beat this downside of the technology, these days research work goes on to implement digital watermarking technique with less information embedding capability. One of the possible ways to reduce the number of bits in information is to use Quick /fast response code (QR Code). The QR code consumes a less space compared to the other existing formats available such as barcode. In this paper Associate in nursing approach is planned to implement the digital watermarking technique for the medical images that includes the following techniques: Integer wavelets Transform (IWT), Bit plane methodology and QR code. For the proposed system, the watermarked image is evaluated against a number of the parameters to grasp the potency of technique being utilized. The experiment is dispensed for 2 totally different bit planes and also the results are compared to point out embedding within which of the bit plane range ends up in additional potency and eventually the conclusion is formed.

    by T. THAMMI REDDY, Madhavi B.K, K. Lal Kishore 
    Abstract: The Xilinx offered Dynamic Partial Reconfiguration (DPR) is a very efficient mechanism to utilize FPGA resources for realizing several application categories. In the context of realizing signal processing data path in area efficient applications several researchers attempted to DPR. The present work demonstrates a generic framework for implementing Software Defined Radio (SDR) based communication system through DPR technique. The work switches contexts with two partial reconfiguration blocks. The first of the DPR block is Spectrum Estimation and second one is FSK receiver. The Spectrum Estimation module is implemented through streaming type FFT architecture. The non-coherent FSK demodulator is implemented using frequency shifting and filtering stages. The major blocks are streaming FFT, complex multiplier, Numerically Controlled Oscillator (NCO), Finite Impulse Response (FIR) filter, peak detection logic and energy detection logic. The completely developed FSK receiver is simulated using Modelsim simulator and results are verified for functional correctness. Xilinx Zynq 7010 SoC with partial reconfiguration feature is used to develop this application. A signal generator that generates FSK signal with symbol rate 64 Kbps bit rate is used to drive the ADC input for testing the application. The work demonstrates novel direction for SDR implementation with DPR technique towards low area FPGA implementation. The results shows that the chosen system can be implementable in a low cost FPGA with 45% lesser DSP48 slice utilization compared to without DPR case. Reduced power dissipation is observed as a by-product of DPR.

  • A new method for the optical flow estimation and segmentation of moving objects "NMES"   Order a copy of this article
    by Amina Ourchani 
    Abstract: Segmention of moving objects in video sequence is a hard, but essential task in a large number of applications in computer vision . Most existing methods gave accepted results only in the case where both object and background are rigid, because of serious occlusions and complex computation, which presents limitations in case of occlusions and shadows. This paper focuses on developing a new method for discriminate moving objects from a static background, focusing on the combination of motion, color and texture features. First, we have used block-matching which is one of the most powerful methods for computing the optical flow, we also have taken in consideration the result of frame difference, to improve the quality of the optical flow. Moreover, we have used the k-means clustering algorithm owing to group the pixels, having similar motion, color and texture features. Second, the result of the grouping pixels is used as an input in Chan-Vese model, in order to attract the evolving contour of moving objects contours. To evaluate the performance of ourvproposed methode, we experiment it on challenging sequences. It has shown that our method provides an improved segmentation results.

    by Hanen Jabnoun 
    Abstract: Vision is an essential human sense which is playing the most important role in human perception about surrounding environment. However such information is generally inaccessible for blind people. In order to enable these persons overcome such incapability, we propose a system for identifying the neighbouring scene. In fact, the environment is labelled as a first step and then we present a personalized and adaptive method for labels detection and recognition. The automatic analysis involves the detection of personalized markers employed to extract the region of interest followed by the perspectives rectification based on homography estimation. We use the stroke width transform to extract the text from the detected label and crop it into words and letters. The extracted text is identified using images correlation. Finally, as a substitution for visual modality, a vocal transformation of the recognized text is performed.

  • Ordered Weighted Averaging Operator used to Enhance Accuracy of Fuzzy Predictor based on Genetic Algorithm   Order a copy of this article
    by Rohit Garg, Md. Tabrez Nafis, Bindu Garg 
    Abstract: Accuracy is one of the most important aspects while designing forecasting model. Particularly in fuzzy prediction system, accuracy considerably depends on subjectively decided parameters such as membership function and relative weight of past observations. In this regard, we have proposed a novel concept to optimize ordered weighted aggregation (OWA) based fuzzy time series predictor (FTSP) using genetic algorithm (GA). Firstly, accurateness of FTSP is enhanced by applying effective method of aggregation on past observations using OWA weights. These weights are determined on the basis of importance of fuzzy set in the system by employing regularly increasing monotonic (RIM) quantifiers. Subsequently, GA is used to optimize membership functions of FTSP by generating its wide range of parameters in the region of time series. Lastly, this model is capable of controlling its performance by varying GA parameters. To assess proposed method, we used dataset of enrollments and outpatient visits, as used by almost all previous research in this domain. Evaluation results indicate coalescing OWA and GA for FTSP significantly reduced mean square error (MSE) and average forecasting error rate (AFER).

  • Improvement of Power quality in Microgrids using Predictive Controller   Order a copy of this article
    by Prajith Prabhakar 
    Abstract: Microgrid is a low voltage grid which is subjected to disturbances. The distributed energy resources are connected to the LV bus by means of power electronic converters. The power quality issues are analyzed with Model Predictive control (MPC) algorithm in both- Grid connected & Islanded modes. But the Islanded mode is analyzed separately. A new model is suggested for the islanded mode with non- linear loads. Predictive control based Distribution static compensator (DSTATCOM) injects voltages at the point of common coupling (PCC) in the Microgrid. Reactive power compensation and mitigation of harmonics are done with the help of new proposed model. The principles and the proposed algorithm are verified by MATLAB/SIMULINK simulation. Simulation results suggest that this control method can decrease the power quality issues and increase the microgrid stability.

    by FEBINA BEEVI PARAYI, T.K. Sunil Kumar, Jeevamma Jacob 
    Abstract: In this study, the authors address the problem of design of a Two Degree Of Freedom (2-DOF) PID controller for time delay systems. The proposed approach is to design 2-DOF PID controller using a novel method which combines model order reduction, approximate model matching concepts as well as optimization techniques. The conventional PID controllers are usually in 1-DOF structure. The problem of finding the parameters of the 2-DOF PID controller is formulated as that of obtaining the solution of a set of non-homogeneous linear equations. The proposed method not only ensures the stability of the closed loop system with a 2-DOF PID controller but also satisfies the required performance criteria. The developed method does not pose any restriction on either the order of the model or on the structure/order of the controller transfer function. Moreover, this method is computationally simple and easy to implement. Simulation results demonstrate the effectiveness of the proposed method.

    by Sumanta Bhattacharyya, Manoj Kumar Mukul 
    Abstract: The requirement of an effective online processing algorithm becomes very vital to fulfilling the demand of the low- cost brain-computer interface (BCI) system. Based on the variation of relative spectral power, the authors proposed an exclusive method of signal processing for the real-time classification of EEG data related with the imagination of left-hand and right-hand movement. The proposed algorithm contains reactive frequency band (RFB) identification and feature extraction process, which make it very first and robust unsupervised machine learning algorithm for the real-time BCI. The RFB has been identified by applying short time Fourier transforms (STFT) based dominant frequency detection algorithm over the training data set. Based on the identified RFB, the temporal relative spectral power (TRSP) based feature extraction process has been applied to the testing dataset. The estimated "feature" further classified as per probabilistic Bayesian classifier. The effectiveness of the proposed RFB detection method of EEG signal is validated by self-generated artificial sine wave signal, single subject and nine subject movement imagery (MI) BCI competition dataset. The proposed method of EEG signal processing outperformed the conventional wavelet-based BCI competition II results and the wavelet-based algorithm applied over the BCI competition IV dataset.

    by Preeti Satish, Krishnan Rangarajan 
    Abstract: IoT systems comprise of multiple devices connected together, to perform an intelligent task in real time. Such systems have to be meticulously tested in order to avoid hazards situations. Combinatorial testing technique can effectively test such complex IoT systems with reduced effort as it generates fewer test cases with adequate coverage. It basically tests the interactions that exist between values of different parameters and practically faults upto six-way interactions have been found successfully. Prioritization of combinatorial tests deals with finding an ideal order of the test cases so that faults are detected early. Recent approaches to prioritization problem are either coverage based or parameter-value weight based for two-way or three-way interaction strengths separately. In this paper, we present a hybrid prioritization technique for combinatorial testing that combines both weight based and interaction coverage based approaches. We derive a combined weight to each test case considering user given weights denoting the importance of values of parameters and the interaction coverage up to six-way interactions. To the best of our knowledge, no research has been carried out yet, that accounts for higher order combinations up to six-way at a time. To demonstrate the effectiveness of our algorithm, we have conducted initial synthetic experiments on various covering arrays, and measured the effectiveness with t-Rate of fault of detection metric. The results are promising in covering the combinations early.

    by Haripriya D, Govindaraju C, Sumathi M 
    Abstract: In this paper, input transition aware adaptive frequency scaling based low power 8 bit Multiplier-Accumulator (MAC) architecture for Digital Signal Processing (DSP) has been presented. As the data transition causes dynamic power dissipation in the electronic circuits, it becomes mandatory to minimize the data transition to minimize the dynamic power. A novel adaptive frequency scaling scheme based on the number of input data transitions is implemented and the dynamic power has been minimized to a greater extent. The proposed input data transition aware adaptive frequency scaling is very effective method to minimize the dynamic power consumption without degrading the performance of the system. The input data transition detector circuit in the proposed low power MAC detects the transition and applies the adaptive frequency scaling based on the number of transitions, so that a notable amount of dynamic power is reduced by the proposed scheme. The dynamic power consumed by the conventional MAC is 77.05mW when all inputs are switching and it is only 2.370mW for the proposed MAC with the same simulation parameters. The proposed MAC consumes 96.92% less power than the conventional MAC for the same set of inputs and simulation environment at 27

    Abstract: Cutting edge frameworks are turning out to be exceedingly configurable to fulfil the shifting needs of clients and clients. Programming product offerings are consequently turning into a typical pattern in programming improvement to decrease cost by empowering deliberate, expansive scale reuse. A few shortcomings may be uncovered just if a specific mix of components is chosen in the conveyed items. Yet, testing all mixes is typically not possible by and by, because of their to a great degree extensive numbers. Combinatorial testing is a method to produce littler test suites for which all mixes of t elements are ensured to be tried. In this paper, we display a few hypotheses depicting the likelihood of irregular testing to recognize connection blames and contrast the outcomes with combinatorial testing. For instance, an irregular testing turns out to be considerably more viable as the quantity of elements increments and focalizes toward equivalent adequacy with combinatorial testing. Be that as it may, when imperatives are available among elements, then irregular testing can passage subjectively more awful than combinatorial testing. Subsequently, with a specific end goal to have a reasonable effect, future research ought to concentrate on combinatorial testing.

    by Sayantani Basu, Marimuthu K, Rajkumar S, Niranchana R 
    Abstract: Genetic Algorithms (GAs) have proved to be a powerful tool in cryptography. The standard AES algorithm incurs high computation costs and has problems in pattern formation when applied to image encryption. It is also prone to the differential and side channel attacks. In this paper, a modification of AES has been proposed for High-Definition (HD) Image Encryption that uses a genetic approach for the S-Box Generation and Key Expansion processes. S-Boxes have been evolved to have high nonlinearity and low transparency. Also, in the key generation, the process has been randomized by using only genetic operators. As a result of applying genetic modifications to AES, the proposed algorithm has been found to be more secure against the differential and side-channel attacks and shows reduced pattern appearance when applied for encryption of HD images.

    Abstract: Network traffic management facing a lot ofchallenges in the recent years because of the continuous and fast development in network scale, number of consumers and type of known and unknown applications over the network. Traffic Classification is a key factor for providing the Quality of network Services (QoS) and also playing a vital role in handling the delay and congestion during the network transmission. In spite of many algorithms existing in the field of network traffic classification, Machine learning algorithms are playing key role. In this paper I would like to discuss about flow based classification models such as port based, payload based, statistical based and behavioral based classifications which are frequently used for identifying traffic classes. Techniques (Methods): Widely used techniques such as port based, pay-load based, behavioral based and statistical based classification models are discussed and sample data sets have been produced with graphical notations to strengthen the analysis process. Findings: This analysis provides the capability to distinguish and isolate the traffic flows into real-time and non-real-time traffic flow according to the process category. Since we are experiencing the integrated environment of multiple fields its very difficult to classify the traffic. So the comprehensive study on these classification models will provide the clarity on how the traffic is classified with different attribute sets and to understand the quality of service and issues of each classification model. Applications:In a wide-range of network environment, traffic classification is more important to provide the differentiated service quality based on the various types of applications and also for monitoring the security over the traffic. In a network traffic analysis, network classification is the first step and core element for network intrusion detection system.There are many network servicing areas where we need to identify and classify the trafficsuch as routing, firewall access-control, policy based routing, traffic billing need to be differentiated and their quality of service has to be assured.
