Interpretive structural modelling: a comprehensive literature review on applications

Abstract: Interpretive structural modelling (ISM) approach is mainly utilised for developing structural relationship among the elements associated with an issue or problem. In recent years, application of ISM approach has tremendously increased in different application areas. In the current work, a comprehensive literature review on the applications of ISM approach has been carried out. This literature review is based on 406 research papers published in 183 journals since its inception. The classification scheme adopted for this paper consists of ten application areas: (1) supply chain and logistics management; (2) quality management; (3) manufacturing system; (4) safety, health and environment management; (5) information management; (6) service management; (7) governance; (8) financial management; (9) energy management; (10) marketing management. Furthermore, literature has been classified on the basis of: (1) integration with other approaches; (2) publication year; (3) publication journal; (4) authors' nationality; (5) ISM version. The literature analysis will act as an information bank for the researchers keen to apply ISM approach in their research area.

Thermodynamic analysis of a novel compact power generation and waste heat operated absorption, ejector-jet pump refrigeration cycle

Abstract: An R-152a ejector-jet pump refrigeration cycle and a LiBr-H2O absorption refrigeration cycle have been integrated with a renewable energy power generator for making a proposed ‘novel compact cogeneration cycle’. The exergy analysis of this proposed cycle leads to a possible performance improvement. Nearly 71.12% of the input exergy is destructed due to irreversibilities in the different components. The useful exergy output is around 7.12%. The exhaust exergy lost to the environment is 21.76%, which is lower than the exhaust energy lost 37.6% of the input energy, while the useful energy output is approximately 19.3%. The refrigerants used and the exhaust gas emissions samples are found to be favourable for reducing the global environmental related problems. The results also show that the coupling of the entrainment ratios of the ejector and jet pump has great effect on the exergy and energy efficiency.

Comparative Analysis of Ontology Ranking Algorithms

Abstract: Ontologies are the backbone of knowledge representation on Semantic web. Challenges involved in building ontologies are in terms of time, efforts, skill, and domain specific knowledge. In order to minimize these challenges, one of the major advantages of ontologies is its potential of “reuse,†currently supported by various search engines like Swoogle, Ontokhoj. As the number of ontologies that such search engines like Swoogle, OntoKhoj Falcon can find increases, so will the need increase for a proper ranking method to order the returned lists of ontologies in terms of their relevancy to the query which can save a lot of time and effort. This paper deals with analysis of various ontology ranking algorithms. Based on the analysis of different ontology ranking algorithms, a comparative study is done to find out their relative strengths and limitations based on various parameters which provide a significant research direction in ranking of ontologies in semantic web.

CATCH: Comparison and analysis of tools covering honeypots

Abstract: Honeypots act as security resources that are used to catch malign activities, so they may be anatomized and watched. During the past few years, they are called as a safeguard of assets of an organization. They are used to acquire information on interrupters in a network. This paper gives an introduction to the honeypots, their classification, detailed study of commercial as well as open source honeypots tools and comparison between them. This paper may be helpful for readers to secure their resources from intruders by using the freely available honeypots tools.

Management of Transaction Exposure: A Comparative Analysis of MNCs in India

Abstract: In an era of globalization, thousands of transactions of international trade take place among companies of different countries. But the profitability of these transactions can be completely wiped out by adverse movements in the exchange rate during this time gap. Transaction exposure is a measure of effect of exchange rate fluctuations on these transactions. Unmanaged transaction exposure can paralyze not only financial position but also competitive position of companies in market. The present study portrays transaction exposure management as practiced by various multinational companies in India. And compares management of transaction exposure by banking and non-banking and foreign and Indian MNCs. The effect of various factors on their management policy is also investigated. The results of the study evidence that the majority of firms make efforts to measure their transaction exposure. There is no significant effect of level of transaction exposure on estimation policy and decision to develop separate management system for management of transaction exposure of companies. Significant difference exists between management policies of companies of different sectors toward management of their transaction exposure. Companies are actively using various hedging strategies for managing their transaction exposure.
