  • Mamdani fuzzy based vehicular grouping at the intersection of roads for smart transportation system   Order a copy of this article
    by Harsha Vardan Maddiboyina, V. A. Sankar Ponnapalli 
    Abstract: Smart transportation system is an innovative solution to the traffic congestion at the real time traffic environment. A smart transportation system based on vehicular grouping technique with length as a parameter has proposed in this research contribution to avoid traffic congestion at the intersection of roads. In this method, vehicles which are waiting at the intersection of roads are divided into small groups with highest priority given to the emergency vehicles. Owing to the proposed work, the average number of vehicles which can cross the junction is increased to 2.4 times compare with existing traffic statistics of Hyderabad City, India. Therefore the average waiting time of an emergency vehicle is diminished up to 38%. Mamdani fuzzy inference system has used to frame the fuzzy IF-THEN rules and MATLAB 2014a has used to simulate the proposed work.

  • The Kushner-Stratonovich Stochastic Method for a Master Robot of a Tele-robotic System: Beyond Extended Kalman Filtering   Order a copy of this article
    by Ravish Hirpara, Shambhunath Sharma 
    Abstract: The surgical robotic system, a tele-robotic system, comprises the operator, master-slave configuration in combination with the object. For the estimation and control of the surgical robotic system, the master-slave set up is the subject of greater robotic research activities as well as has proven promising. The noise equations as well as their extended Kalman filtering are available in literature in a greater detail. In this paper, the multi-dimensional stochastic differential equation as well as the higher-order nonlinear stochastic filter beyond extended Kalman filtering for a master robot of the surgical robotic system are developed. The higher-order non-linear filtering preserves the greater qualitative characteristics of non-linear stochastic systems by accounting observation correction terms in stochastic evolution equations. First, the Lagrangian mechanics is exploited to develop the vector stochastic model of the master robot. Secondly, this paper utilizes the Kushner-Stratonovich equation, a celebrated systems and control method in stochastic systems literature, for filtering of the master robot noise equations. This paper demonstrates comparison between the higher-order Kushner-Stratonovich filter, extended Kalman filter and true state trajectories as well. Importantly, this paper will be of interest to robotic dynamists and control theorists aspiring for formal, systematic non-linear stochastic methods with greater conceptual depth in robotic dynamics, which are not researched yet in literature.

  • An Iterative Solution Approach for Steady State Analysis of Self-Excited Induction Generator   Order a copy of this article
    by Hayri Arabaci 
    Abstract: The steady state analysis of self-excited induction generator is widely used for stand-alone renewable energy system. The impedance values of equivalent circuit vary depending on frequency. The frequency changes according to load, excitation capacitance and rotor speed. If the values of load and capacitance are known, only the frequency and slip are the two main unknowns left for analysis of the single-phase equivalent circuit. The simulation is generally performed for a desired slip value to obtain the frequency. However, with the proposed approach in this study, the values of rotor slip, and frequency of terminal voltage are both directly determined. The proposed algorithm is verified by the experiments of three phase 1.1 kW squirrel cage induction machine.

  • New weighted clustering ensemble based on external index and subspace attributes partitions for large features datasets.   Order a copy of this article
    by Nadjia Khatir, Nait-Bahloul Safia 
    Abstract: Real world datasets are commonly large and involve a lot of features. This is due because of the variety of domains where are obtained from or for the impact of diverse features extractors techniques. Relatively few works on selecting and weighting relevant features for the propose of clustering data are involved in the literature. To cope with this issue, in this paper a new weighting partitions based features selection framework is proposed in conjunction with clustering ensemble for large features datasets. The clustering framework proposed is designed at two different levels: at the first level, from the original dataset, partitions of features are generated based on graph partitioning methods, where the nodes represent the features vectors and the links (edges) are the correlation coefficients between these features, then, as each subset of features gives different representation of the same data, a baseline clustering algorithms on each subset are applied. At the second level, a new clustering ensemble scheme is proposed to combine the whole partitions by proposing a new weight based on external index to ass the quality weight of each clustering partition before incorporating them into the final partition of the dataset. Six real world datasets from both images and biological domains are chosen to be evaluated and an average accuracy between 75:18% and 98:04% is achieved. Results show that the new proposed technique have been successfully outclassed state-of-the-art methods in term of both effectiveness and efficiency.

  • Heat Transfer Dynamics Modeling by Means of Clustering and Swarm Methods   Order a copy of this article
    by Oualid LAMRAOUI, Yassine BOUDOUAOUI, Hacene HABBI 
    Abstract: This paper deals with the modeling problem of heat transfer dynamics in thermal exchanger process by using fuzzy prediction approaches. Clustering and swarm based optimization methods are used to derive heat transfer dynamical models to predict temperature variations of hot and cold fluids in the exchanger. The clustering method relies on a one-shot potential calculating strategy to extract the fuzzy sets distribution from the data space. However, the swarm optimization method employs a subject function to optimize the premise and conclusion parameters of the fuzzy structure. Experimental data extracted from a pilot exchanger process is used to learn the fuzzy models, and their performances are compared on both training and testing measurement data.

  • Performance evaluation of conventional and Fuzzy control systems for speed control of a DC motor using Positive Output Luo Converter   Order a copy of this article
    by Mohamed BOUTOUBA, Abdelghani El Ougli, Belkassem Tidhaf 
    Abstract: Precise speed control of DC motors is an important requirement for efficient industrial automation and diverse applications fields. In this paper, a speed control of a DC motor for a photovoltaic system is proposed using fuzzy logic technique as a controller with a DC-DC converter type Positive output Luo converter. Positive Output Luo converter, one of a new generation of DC-DC converters which presents multiples advantages, is used as an intermediary between the photovoltaic source and the DC motor, in order to control the transmitted power with low power losses. Multiples classical control techniques could be used to control DC motor speed. However, in this work a PI Fuzzy logic controller is proposed to get better pursuit, response and speed accuracy which represent important parameters to control on some industrial applications. Different system blocks are developed on Matlab/Simulink as environment. Simulation results, using comparison between a Conventional PID controller and the PI-Fuzzy Logic controller, demonstrate the good behavior of the proposed system.

    by Viorica Rozina Chifu, Emil Stefan Chifu, Ioan Salomie, Cristina Bianca Pop, Madalina Lupu 
    Abstract: Biologically-inspired computing is an interdisciplinary research domain that brings together principles from mathematics, computer science and biology in order to develop intelligent algorithms or high performance computing models that are able to capture the social behaviour of animals, insects, birds or other living organisms. Recently, bio inspired computing has been successfully applied for solving problems in the e-health domain. This chapter addresses the problem of optimality in the e-health domain by proposing an evolutionary-inspired method for clustering patients according to the risk of having diabetes. This method clusters patients based on their similarity with respect to the following features: age, sex, race category, body mass index, whether the patient has or hasnt hypertension, and the presence or absence of first-degree relatives with diabetes. Our method has been tested on the NHANESIII data set

  • Empirical Investigation of Dimension Hierarchy Sharing Based Metrics for Multidimensional Schema Understandability   Order a copy of this article
    by Anjana Gosain, Jaspreeti Singh 
    Abstract: Over the last years quality has gained lot of importance in the development of data warehouse systems. Predicting understandability of multidimensional schemas could play a key role in controlling data warehouse quality at early stages of development. In this area, some effort has been spent to define structural metrics and identity models for assessing quality of these systems. Of the structural properties used to define metrics, aspects of dimension hierarchies and its sharing plays primary role to enhance analytical capabilities of multidimensional schemas, thereby affecting their quality. The authors have previously proposed structural metrics based on aforementioned aspects. The objective of this study is to apply Principal Component Analysis (PCA) to find whether our metrics are improvements over the other existing metrics; and to apply Logistic Regression to study whether the metrics (selected as relevant in the extracted principal components) combined together are indicators of multidimensional schema understandability. The results of PCA confirm that our structural metrics based on the concept of sharing are different from other such metrics existing in the literature. Further, the metrics selected as principal components can be used in combination to predict understandability of data warehouse multidimensional schemas.

  • Detecting Concept Drift using HEDDM in Data Stream   Order a copy of this article
    by Snehlata S. Dongre, Latesh G. Malik, Achamma Thomas 
    Abstract: In evolving Data Stream, when its concept undergoes a change it is known as concept drift. Detecting Concept Drift and handling it is a challenging task in Data Stream Mining. If an algorithm is not adapted to Concept Drift, then it directly affects its performance. A number of algorithms have been developed to handle concept drift, but they are not suited for both - Sudden Concept Drift and Gradual Concept Drift. Thus, there is a demand for an algorithm that can react to both the types of concept drift as well as incur less computational cost. A new approach - Hybrid Early drift Detection Method (HEDDM) - has been proposed for drift detection, which works with an ensemble method to improve the performance.

  • Dynamic Social Network Analysis and Performance Evaluation   Order a copy of this article
    by Sanur Sharma, Anurag Jain 
    Abstract: Social media in todays age is on a tremendous increase in terms of its usage and the enormous amount of data it generates which includes personal details of users, their images and the content that is being shared on such open source platforms. This has led to a lot of research and analysis of such networks and data that exists in social media. This paper is focused on dynamic analysis of social networks, where snapshots of network are taken at regular intervals and are analysed on various performance measures. The real time email dataset of a company (ENRON) has been evaluated and visualized dynamically. The network measures are evaluated at each timestamp and clustering is performed on that data and its performance is calculated on various measures. Tabu search optimization algorithm has been used for clustering the timestamped data and a comparison is done between the fixed size cluster and variable size clusters. The results suggests that for certain time stamps the value of precision, recall and f measure for fixed size clusters are better than the variable size clusters. These measures can further be used for the selection of the dynamic clustering techniques for social network analysis.

  • Measuring harmfulness of class imbalance by data complexity measures in oversampling methods   Order a copy of this article
    by Deepika Singh, Anjana Gosain, Anju Saha 
    Abstract: Many real world applications consist of skewed datasets which result in class imbalance problem. During classification, class imbalance cause underestimation of minority classes. Researchers have proposed a number of algorithms to deal with this problem. But recent research studies have shown that some skewed datasets are unharmful and applying class imbalance algorithms on these datasets lead to degenerated performance and increased execution time. In this research paper, we have pre-estimated the degree of harmfulness of class imbalance for skewed classification problems, using two of the data complexity measures: scatter matrix based class separability measure and ratio of intra-class versus inter-class nearest neighbors. Also the performance of oversampling based class imbalance classification algorithms have been analyzed with respect to these data complexity measures. The experiments are conducted using k-nearest neighbor (k-nn) and naivebayes as the base classifiers for this study. The obtained results illustrate the usefulness of these measures by providing the prior information about the nature of the imbalance datasets that help us to select the more efficient classification algorithm.

    by Aarti Aarti, Geeta Sikka, Renu Dhir 
    Abstract: Software metrics has become desideratum for the fault-proneness, reusability and effort prediction. To enhance and intensify the sufficiency of object-oriented (OO) metrics, it is crucial to perceive the relationship between OO metrics and fault-proneness at distinct severity levels. This paper characterize on the investigation of the software parts with higher probability of occurrence of faults. We examined the effect of thresholds on the OO metrics and build the predictive model based on those threshold values. This paper also instanced on the empirical validation of threshold values calculated for the OO metrics for predicting faults at different severity levels and builds the statistical model using logistic regression. This paper depicts the detection of fault-proneness by extracting the relevant OO metrics and focus on those projects that falls outside the specified risk level for allocating the more resources to them. We presented the effects of threshold values at different risk levels and also validated results on the KC1 dataset using machine learning and different classifiers. The results evaluated on the Receiver and operator (ROC) parameters concluded that threshold methodology has great potential for conducting prediction of faults and shows that analysis of result using machine learning techniques outperforms as compared to logistic regression.
