  • Multi-objective optimisation of Mahua oil transesterification using response surface methodology and grey relational analysis   Order a copy of this article
    by R.R. Neela Rajan, R. Rajesh 
    Abstract: A mathematical model for the transesterification of Mahua oil was developed at five different process parametres such as catalyst concentration, methanol to oil ratio, reaction time, stirrer speed and extraction temperature. A three-level-five factorial Box-behnken-response surface methodology (RSM) was employed to design the experiment. Analysis of variance (ANOVA) of experimental results at 95% confidence level showed that catalyst concentration and methanol to oil ratio were significant process parametres in the transesterification process and the predicted values were quite close to the experimental values, thus, validating the credibility of the model. The grey relational analysis (GRA) was employed to optimise the process parametres for minimising the viscosity of transesterified Mahua oil and maximising the yield of Mahua oil biodiesel.

    by Sonu Rajak, P. Parthiban, R. Dhanalakshmi, Sujith S 
    Abstract: The Capacitated Vehicle Routing Problem is a combinatorial optimization problem that determines a set of routes of minimum distance to deliver the goods, using a fleet of identical vehicles with restricted capacity. The objective of this article it to optimize the total distance required to deliver the goods and also the workload imbalance in terms of distances travelled by the vehicles and their loads. Due to the combinatorial in nature, it requires metaheuristic to solve these types of problems and this is a rapidly growing field of research. Here two metaheuristics such as Ant Colony Optimization (ACO) and Simulated Annealing (SA) are proposed and analyzed for solving this multi-objective formulation of the Vehicle Routing Problem. The results obtained from these two methods were compared and found that the ACO gives better results than the SA for the VRP.

  • SELECTION OF SUPPLIERS USING SWARA AND COPRAS-G   Order a copy of this article
    by Rajesh G, Malliga P 
    Abstract: In order to optimize a supply chain, the effective management of suppliers plays a key role. Firms seeking competitive advantage are participating in cooperative supply chain arrangements, such as strategic partnerships, which combine their individual strengths and unique resources. Supplier selection is a multicriteria decision making problem which includes both qualitative and quantitative factors. In the present scenario environmental criteria should also be given due importance, this further increases the challenge of supplier selection. Generally, decision makers judgments are often uncertain and cannot be estimated by an exact numerical value. The grey systems theory is a powerful tool to deal with uncertain information. This paper presents a structured model for evaluation and selection of strategic supplier. Stepwise Weight Assessment Ratio Analysis (SWARA) is applied to decision making in order to calculate the relative importance of the criteria. The COmplex PRoportional ASsessment of alternatives with Grey relations (COPRAS-G) method is used for supplier evaluation and selection of strategic supplier. A case study is presented to demonstrate the applicability of the proposed model to select a strategic green supplier.
    Keywords: strategic supplier selection; complex proportional assessment of alternatives with grey relations; COPRAS-G;stepwise Weight Assessment Ratio Analysis; SWARA; MCDM; Green supplier selection.

  • Entropy a new measure to gauge search engine optimization   Order a copy of this article
    by Batri Krishnan 
    Abstract: This article tries to analyze, and measure the uncertainty associated with the relevant document selection in web-search engines. The web-search engines process, organize the web-documents based on their index term's occurrence frequency. The number of index terms, and their occurrence frequency influences the relevance calculation. The variation in term frequency either in processed web documents or in users' query influences the relevance calculation. This leads to an uncertainty associated with the document selection, and its relevance calculation. In this article, we proposed a new measure called Entropy, to calculate the uncertainty associated with the document selection. The Entropy can be measured by varying the documents' term frequency or user's query term frequency. As the web documents can't be changed, we used variation in user's query term frequency to measure the uncertainty associated with the document selection in web-search engines. The experiments are conducted on two search engines namely 'Google', and 'Bing'. The query's term frequency is varied and given to the search engines. Based on our proposed method, the uncertainty is calculated for the search engines. The high Entropy value indicates the high uncertainty associated with the document selection. The high uncertainty gives scope for search engine optimization. From the high uncertainty search engines, we can extract more relevant documents. It can be used as a performance indicator.
    Keywords: web search engines; uncertainty; entropy; document selection; Google; Bing; Search Engine optimization.

    by Manthandi Periannasamy Subramanian 
    Abstract: Security issues are the primary issues in Wireless Sensor Networks (WSN) due to its large network coverage and number of nodes. The attackers in WSN attack the particular node which has low energy level and converts this node into malicious node. The formation of malicious node is the primary reason for link failures between nodes. This paper proposes an efficient methodology to detect the malicious nodes in WSN using feed forward back propagation neural netwok classifier. This classifier differentiates the malicious node from trusty node based on the extracted features of the test node. The performance of the proposed malicious node detection system is analyzed interms of detection rate, Packet Delivery Ratio (PDR) and latency. The experimental results are compared with state-of-art methods

    by Kavitha V 
    Abstract: Many parameters can be measured and stored in the black box. The details stored in the black box are essential for the analysis of causes of the accident. In the formal black box, data is stored and it can be retrieved only after the identification of black box after crash. So it is very difficult to identify the exact location of the black box after a crash. Many leading officials and famous personalities died in air crashes and it takes a lot of time to identify the location of crash. It leads to wastage of money and time. Saving human life is the basic nature of humanity. In this article, black box data is transmitted to an earth station. The details are updated to the base station through wireless medium. It is transmitted to selected base stations by calculating the shortest path between them using ad hoc algorithm. Ad hoc algorithm is a multi hop network algorithm which switches to various stations by calculating its distance. Thus black box data is updated to base station wirelessly using ad hoc algorithm.

  • An Anomaly-based Network Intrusion Detection System using Ensemble Clustering   Order a copy of this article
    by Jackins V 
    Abstract: Due to the rapidly increasing use of internet services and computer applications all over the world, the numbers of hacking and intrusion incidents are increasing year on year as technology rolls out. Therefore, Intrusion Detection Systems (IDS) are the prime need in todays scenario [1]. Misuse detection can detect previously known attacks but cannot detect new types of attacks[24]. To overcome this limitation Anomaly detection techniques are often used and proven to be an effective method. Anomaly detection can make use of unsupervised techniques to identify new types of attacks [12]. In this paper, an unsupervised technique is used for Anomaly detection based on hybrid clustering algorithms. The technique uses two algorithms in order to obtain accurate and high detection rate of attacks. [15] Incremental Support Vector Machine (ISVM) algorithm is used to preprocess the dataset. After Preprocessing, Fuzzy C Means (FCM) algorithm is adopted to detect the anomalies. FCM algorithm isolates the normal and abnormal data effectively. The processed data is fed to the DBSCAN algorithm for further detection of anomalies. The results of the detection system are communicated to the Intrusion Prevention System (IPS) which is responsible for sharing a suitable response to an anomalous request. The proposed hybrid algorithm is applied for KDD Cup 1999 dataset, Gure Kdd Cup data base (2008) and the results shows high detection rates and low false positive alarms. Further, the technique is tested with a real time data and it is observed that a high detection rate of anomalies with enhanced true positive rate.
