Investigation on effect of geometric, material and load parameters on strength of composites with cutouts
by Anoop Kumar S, Rajesh R
Abstract: Composite applications require presence of multiple holes for mechanical fasteners or cutouts in laminates. Holes and cutouts help in lightening composite laminates used as aerospace structures. Unlike isotropic materials, composite materials experience change in stress values due to different parameters such as geometric, material and loading parameters. The present study is devoted to primarily determine whether geometric, material or loading parameters have dominant influence on strength of composite laminates. Geometric parameters such as cutout shape, size, orientation, proximity (in case of multiple holes) as well as edge interaction are taken into consideration. Among material parameters, fiber material, fiber orientation and stacking sequence are varied. Numerical study using ABAQUS CAE software is employed for the analyses. Experiment on Open Hole Tension specimen as per ASTM standards is also conducted to validate the numerical model. Results reveal that geometric parameters have much significant influence on stress concentration factor and thereby the strength of composite laminates, when compared to material parameters. Among the geometric parameters, edge interaction is the most critical factor affecting the stress concentration. An elliptical cutout is seen to have comparatively more adverse effect on strength of laminate, when compared with other cutout shapes. Further, effect of load parameters in-plane tension, compression and shear, is also studied. However, no effect was evidenced in stress concentration factor due to load parameters.
Keywords: Stress Concentration Factor; Composite Laminate; Edge Interaction; Open Hole Tension; Geometrical parameters; Material parameters; Load parameters.
Experimental Study on the Influence of Fiber Surface Treatments and Coconut shell Powder addition on the Compressive strength, Hardness and Tribological properties of Sisal fiber-Natural Rubber Composites.
by Gopakumar R Nair, Rajesh R
Abstract: In the contemporary age of global imbalance and disasters, toxic wastes and their waste disposal is a major concern for the humankind. Development and utilization of natural materials as a viable replacement for synthetic materials in product design and development is the only long-term solution for this problem. This work aims to design and develop an elastomer composite material using 100% natural materials only- natural rubber composite reinforced with sisal fibers with improved tribological and compressive properties. Since rubber products are widely applied in industries and automotive parts, the developed material can find its place in elastomer components. A total of six composites are made with sisal natural fibers subjected to various surface modifications as reinforcement and a 10%w/w coconut shell powder as fillers in a natural rubber matrix. Sisal fibers used are raw fiber, Alkalized fibers, rubber pre-impregnated raw fibers and Rubber Pre-impregnated Alkalized fiber. The specimens are tested for wear resistance, compressive strength and hardness. It is found that sisal is a good reinforcement for enhancing the above properties of natural rubber. Maximum wear resistance exhibited by the Alkalized pre-impregnated Sisal-Rubber composite, followed by raw pre-impregnated-Coconut shell powder-Rubber Composite. The hardness of the composites Raw Sisal-Rubber and Raw Pre-impregnated improved by 228% than pure rubber (25 Shore A). Compressive strengths also improved to a notable level. The Composite raw Sisal-Coconut Shell powder-Rubber has the best compressive strength.

An Automatic Construction of Domain Ontology to Analyze Competence Prerequisites of Jobs
by KUMARESH N, J. ABDUL SAMATH
Abstract: In many industries, the hiring process is a critical task, where many applicants will be applied for the single position, so it is required to analyze their qualification which ought to suit the requirement. Identifying feasible candidate with the required knowledge and skills is the difficult task which is faced by the organizations. In the earlier work, Job-Know Ontology (JKO) is built, which gives interlink connection among the job, skills and the competence level of the particular job. Nevertheless, this ontology can be utilized to know only the specific job position where various ontologies were required to be built for the various jobs. It is very difficult to make the students start their feasible career. The ontology requires updating manually for time being to adjust the existing competence level. In the proposed work, this issue is rectified through Domain Ontology Construction Framework (DOCF) from the job knowledge thesis and the job requirements details, which are obtained from online. The obtained documents were clustered regarding the content and conceptual similarity based clustering method. From those clustered documents Job-Know ontology will be built. So it is easy to create the information requirements about the job search phase by both candidates and the Human resources (HR) of the industries. It is proved that proposed research method leads to give better result when compared with the existing research method in terms of increased accuracy rate.

Selection of suppliers using Swara and Copras-G
by G. Rajesh, P. Malliga
Abstract: In order to optimise 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 multi-criteria 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.

Entropy a new measure to gauge search engine optimization
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.

Wireless system for flight safety industry
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.

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 . Misuse detection can detect previously known attacks but cannot detect new types of attacks. 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 . 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.  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.

Authentication as a service in cloud from a fuzzy perspective
by S. Vijayalakshmi, G.R. Karpagam
Abstract: In a cloud based online voting system, the life cycle starts with voter registration, authentication, voting and counting. The election process is a secret process as whole democratic administration is centralised on voting. Authentication, confidentiality, integrity, scalability, speeds and accuracy these are few important criteria to be satisfied by an online voting system. Authentication can be considered as the most critical issue among all the above. So the voters should be kept at the highest priority to make the voting process fair and effective. Through some of the literatures that deal with the issue of authentication mechanisms, the proposed method conceals the original biometric template such that it is impossible to recover the biometric template even when the stored data in the system is open to an attacker. We assess the system with relativity matrix between security requirements, issues, techniques and mechanisms.

by SENTHIL KUMAR PONGALLIAPPAN, Abdul Samath
Abstract: Improved utilization of network based communication enhances the amount of document generation from which discovery and taking back of user needed documents depends upon their requirements is a very complicated task. This could be solved by building the personalized user profile depending on their interest by utilizing which user needed documents that are alike to their inquiry could be got back. In the previous work, Information Retrieval System utilizing Differential Weighting Scheme (IRS-DWS) has been presented that builds the user profile with the point of subjects and recurrent terms exists in the user retrieved documents. On the other hand, this work does not focus on the idea of user queries and take back the documents wherein terms concerned more devoid of thinking the concept. In addition, the previous works do not concentrate on the identical demands from the numerous users where it will process individual user needs only, therefore it will result in more computational overhead. This issue is solved in this work by presenting Improved Information Retrieval System utilizing Cooperative Ontological based User Profile Construction (IIRS-COUPC). In this research work, cooperative ontology based user profile (COUP) is built to take back the documents from diverse ideas that matches with the users demand. In order to make simplicity of document looking for process and merges the numerous users with identical demands, documents clustering (DC) and Query Clustering (QC) is accomplished in this work independently. Lastly, Concept Mapping (CM) is accomplished to take back the documents which matches with the user needs proficiently. The whole assessment of the current research work is accomplished in the java simulation environment from which it is shown that the current research methodologies confirms its improved performance.
