The quality award programmes are applied worldwide. The various quality awards are the criteria for measuring performance excellence. They represent the framework for high-performance management system. In this paper the authors intend to (i) develop a quality award model based on commonalities among criteria of existing quality awards, (ii) develop interdependencies at system/sub system level and (iii) use inheritance and interdependencies to evaluate a numerical index for the developed model using graph theoretic approach. The framework incorporates the critical factors of quality evolution, which further implied for TQM implementation. © 2012 The Society for Reliability Engineering.

In this paper, design of compact rectangular microstrip patch antenna (RMPA) using square grid of rods and I shaped metamaterial is presented. To achieve miniaturization of reference patch antenna resonating at 5.2 GHz, I shaped metamaterial is embedded underneath the patch which shifts the resonating frequency to lower side at 4.36 GHz and thus provide 33% compactness in size. Embedding a square grid of rods beneath the patch provides dual band at 2.56 GHz and 4.03 GHz. Besides providing the compactness, both technique also improves the returns loss and enhances the bandwidth. © 2015 IEEE.

To manufacture a product, nowadays there are many methods available in the market to manufacture them and to earn more profits and best production which is the prime focus of any manufacturing industry, it is necessary to select only that type of manufacturing process which leads to more profits, less scraps, and reworks, faster production rate, good quality of production, employee satisfaction, customer satisfaction, etc. So the aim of this paper is to judge the best manufacturing process among various manufacturing processes for manufacturing any product using graph theoretic approach. The graph theoretic approach reveals a single numerical index and accordingly it is possible to choose the best manufacturing process. To apply the graph theoretic approach the authors selected four factors namely: Quality, Cost, Technical Capability, and Production. Based on these factors and their co-factors a fish bone diagram is represented. While applying graph theoretic approach a digraph of the characteristics is drawn which represented the factors and co-factors affecting the selection of manufacturing process and further the interdependency of the factors as well as their inheritances has been identified and its representation in the matrix form has been used for the calculation of numerical index of the manufacturing process through its variable permanent quality function. The technique is applicable when there are more than options are available for manufacturing a product. An example is also shown in the last of the paper to understand the application of graph theoretic approach for the selection of best manufacturing process among three processes. © 2012 The Society for Reliability Engineering, Quality and Operations Management (SREQOM), India and The Division of Operation and Maintenance, Lulea University of Technology, Sweden.

In a Question Answering system, the user submits a question and waits for the answer as the response. If the system is capable of predicting the user's future interest as the next question, its performance will improve greatly. This paper predicts users' future questions based on the current interaction records of the user with the system. Their current interactions with the system show what they are interested in. These interaction records are maintained in the form of Questions log from which the user sessions are extracted. Based on the user sessions, the system predicts the next question for which the user may become interested in near future. A sample Questions Log is selected for the purpose of performing experiments. The model of Association rule mining is applied to predict the future question of the user. © 2015 IEEE.

The bottom-up construction and operation of machines and motors of molecular size is a topic of great interest in nanoscience, and a fascinating challenge of nanotechnology. The problem of the energy supply to make molecular motors work is of the greatest importance. Stimulated by chemical reagents, electricity, or light, artificial molecular machines exhibit precisely controlled motion at the molecular level; with this ability molecular machines have the potential to make significant impacts in numerous engineering applications. Research in the last ten years has demonstrated that light energy can indeed be used to power artificial nanomotors by exploiting photochemical processes in appropriately designed systems. More recently, it has become clear that under many aspects light is the best choice to power molecular motors compared with molecular machines powered by chemical or electrical energy. The following issues are significant for light-driven artificial molecular machines in the following aspects: their chemical structures, motion mechanisms, assembly and characterization on solid-state surfaces. Applications in different fields of nanotechnology such as molecular electronics, nanoelectro- mechanical systems (NEMS), nanophotonics, and nanomedicine are envisaged. This short review will focus on the use of light to power artificial molecular motors and machines. It is intended to discuss the design principles at the basis of light-driven artificial nanomotors, and provide an up-to-date overview on the prototype systems that have been developed. © Research India Publications.

In this paper, an attempt has been made to determine the proper location of STATCOM and series compensator working independently as well as simultaneously for improving the transient stability of a multi machine power system. The transient stability condition is usually assessed by evaluating critical clearing time (CCT), i.e. maximal fault duration for which the system remains transiently stable. The CCT is obtained by increasing the fault time interval until the system loses its stability. The effect of variation of generator loading, reference source voltage of STATCOM and degree of compensation on transient stability condition has also been considered at various locations of STATCOM and series capacitor. The results indicate the importance of installing STATCOM to a power system due to their effect of not only on stabilizing the system voltages but also increasing the power system critical clearing time in case of unrepeated three phase ground fault. Increase in CCT can help in the reliable operation of the protection system and reduce the protection system rating and its cost. © 2012 IEEE.

In recent years, semantic search for relevant documents on web has been an important topic of research. Many semantic web search engines have been developed like Ontolook, Swoogle, etc that helps in searching meaningful documents presented on semantic web. The concept of semantic similarity has been widely used in many fields like artificial intelligence, cognitive science, natural language processing, psychology. To relate entities/texts/documents having same meaning, semantic similarity approach is used based on matching of the keywords which are extracted from the documents using syntactic parsing. The simple lexical matching usually used by semantic search engine does not extract web documents to the user expectations. In this paper we have proposed a ranking scheme for the semantic web documents by finding the semantic similarity between the documents and the query which is specified by the user. The novel approach proposed in this paper not only relies on the syntactic structure of the document but also considers the semantic structure of the document and the query. The approach used here includes the lexical as well as the conceptual matching. The combined use of conceptual, linguistic and ontology based matching has significantly improved the performance of the proposed ranking scheme. We explore all relevant relations between the keywords exploring the user's intention and then calculate the fraction of these relations on each web page to determine their relevance with respect to the query provided by the user. We have found that this semantic similarity based ranking scheme gives much better results than those by the prevailing methods. © 2013 IEEE.

This paper presents vibration control performance of quarter car model with three-degrees-of-freedom having Magneto- Rheological (MR) suspension system. Experimental work is performed on an MR shock absorber prototype under various cyclic excitation conditions. A polynomial model is selected to characterize the test results of MR shock absorber. The designed forward fuzzy logic controller (FFLC) and inverse fuzzy logic controller (IFLC) are assembled in the secondary suspension system of quarter car model. The response plots in time domain due to bump road disturbance related to passenger seat are obtained for uncontrolled and controlled quarter car models. Simulation results are compared for selection of best option which can provide maximum ride comfort to travelling passengers. Simulation results demonstrate that semi-active quarter car system provides improved overall performance in terms of passenger ride comfort and safety compared to uncontrolled system. © 2014, Springer-Verlag Berlin Heidelberg.

Software development process leads to the delivery of high-quality software product that satisfies the user requirements. Accordingly, the developed software product should be able to change or evolve after delivery. AOSD aims at encapsulating crosscutting concerns through a new construct class like Aspect and localize the change. Hence, it encapsulates the behavior affecting multiple classes into the reusable module. Moreover, the software maintenance is not only to correct faults but also to extend the software for implementing new or changed user requirements which concerns functional enhancement hence a new maintainability model is proposed for AOSD with extensibility as sub characteristic. As every proposed model requires evaluation hence in order to evaluate the proposed maintainability model we had used Analytical Hierarchy process (AHP) as an approach. © 2015 IEEE.

Page Ranking techniques are employed by search engines to rank the web pages in order of their importance and relevance to user query. Many current approaches to page ranking either focus on link-structure of the Web or similarity of a page with the query to calculate Page Rank values of the pages., These traditional approaches however do not at all consider user preference, feedback and user interest while page ranking. In a typical scenario where users generally do not look at pages which come after first result-page using these factors (user preference, user feedback) along with traditional page ranking factors can significantly improve ordering of results. In this a paper a new page ranking algorithm is being proposed that combines page similarity, link-structure information with user preference based on Internet domains and implicit user feedback (based on number of clicks and time spent on web page) for page ranking. Preliminary small user study results conforms improved quality of the proposed mechanism wherein user gets desired information without going deeper into the search results. © 2015 IEEE.
