Radiation is a volumetric phenomenon, and all solids, liquids, and gases emit, absorb or transmit radiation. However, radiation is usually considered to be a surface phenomenon for solids that are opaque to thermal radiation such as metals, woods and rocks since the radiation emitted by the interior regions of such material can never reach the surface, and the radiation incident on such bodies is usually absorbed within a few microns form the surface. Finned surfaces are used widely in industries, which due to their high temperature transferring heat by radiation is important. One of the this industry is space application, where the heat is transferred on in the mode of radiation. So, having the least material in very important in this industry. In this paper, Longitudinal fins with rectangular, triangular, concave, and convex profiles have been studied to establish the optimum dimensions based on the least material. The results showed that the concave parabolic has the best performance among other types of fins.

In this study, tin selenide was prepared at different ratios using tin and selenium pellets in glass tube filled with argon and then heated up to 350°C. The resulting materials were cut into ingots which were used in preparation of thin films by thermal evaporation. The evaporation was done using Edwards auto 306 coating unit. The chamber pressure was maintained at 5.0 x 10-5mbars during the film deposition. Thin films of tin-selenide produced using various ratios were characterized for optical properties and sheet resistance. The optical measurements were done using UV-VIS-NIR spectrophotometer Solid State 3700 DUV in the visible range (380-750nm) and the transmittance spectra data obtained was analyzed using the SCOUT software. The films with ratio of 1:1 showed the highest transmittance of 85% with a band gap energy obtained as 1.40eV. The electrical characterization measurements were carried out using a four point probe at room temperature (25°C) to obtain the sheet resistivity. The resistivity obtained for the films was 20.1?cm.

According to Betz, the maximum conversion efficiency of a wind turbine is 59.3%. But, the wind turbine works at efficiency of 25% to 35%. Hence, there is an opportunity to improve the efficiency of wind turbine. If, the efficiency of wind turbine is increased by at least 1%, it could turn into giant profits. Multiple nozzle system, therefore, if it is used, it increases the velocity of air, huge. The effect of multiple nozzle system is studied in the present article. The theoretical power coefficient and actual power coefficients of wind turbine are determined as part of the study. Few experiments were taken up earlier to increase wind speed using single nozzle system. But, multiple nozzle system is first ever, used in the history. The effect of conversion of heat energy into kinetic energy using multiple nozzle system is presented in this article. The design of multiple nozzle system obtained patents in India.

This paper emphasize on how parallelism can be applied in Data Analysis. In recent decades, where the large amount of data is produced by machines: software logs, cameras, microphones, RFIDs, etc. Creation speed rate of these data will increase exponentially with Moore’s Law. Saving or storing such amount of data is inexpensive and using some parallel processing methods, the data can also be investigated and mined effectively. So this article intends to debate about parallel programming procedures used in Data Analysis and Data Mining. The key motive for this parallelism is to make analysis more rapidly. This is generally attained by using multiple processors or multiple computers, execution dissimilar aspects of data analysis or mining, performing the tasks alongside and later consolidating the data into a single report.

Oral controlled drug delivery systems represent the most popular form of controlled drug delivery systems for the obvious advantages of oral route of drug administration. However, there are certain conditions for which such a release pattern is not suitable like cardiovascular diseases, Diabetes mellitus, Asthma, Arthritis, Peptic ulcer etc. In such cases pulsatile drug delivery system is used in which release drug on programmed pattern i.e. at appropriate time & at appropriate site of action. Pulsatile Drug Delivery systems are basically time controlled drug delivery systems in which the system controls the lag time independent of environmental factors like pH, enzymes, gastro-intestinal motility, etc. The principle rationale for the use of pulsatile release is for the drugs where a constant drug release, i.e., a zero-order release is not desired. In chronopharmacotherapy drug administration is synchronized with biological rhythms to produce maximal therapeutic effect & minimum harm for the patient. Technically, pulsatile drug delivery systems administered via the oral route could be divided into two distinct types, the time controlled delivery systems and the site-specific delivery systems, thus providing special and temporal delivery. In recent pharmaceutical applications involving pulsatile delivery; multiparticulate dosage forms (e.g. pellets) are gaining much favor over single-unit dosage forms. Designing of proper pulsatile drug delivery will enhance the patient compliance, optimum drug delivery to the target side & minimizing the undesired effects.

The purpose of regression testing is to ensure that bug fixes and new functionality introduced in a new version of a software do not adversely affect the correct functionality inherited from the previous version. Regression testing is an expensive and frequently executed maintenance process used to revalidate modified software. It is costly but crucial problem in software development. The paper try to do the survey of current research on regression testing and current practice in industry and also try to find out whether there are gaps between them.

The main purpose of this paper is to present the importance of benchmarking in TQM and organizational performance. To determine the various benefits an organization can derive from the application of total quality management practices, or the relationship between total quality management and quality outcomes/benefits in services sector of telecom industry of Pakistan. The study is based on primary and secondary data. Eight most important constructs were found through literature review for conceptual framework in this study. Primary data is collected through questionnaires. The same questionnaire was used in comparison of TQM practices in different countries such as India, USA, Mexico, China and Norway. The theoretical framework adopted is by Raghunathan et al. (1999). Findings revealed that TQM practices and implementation have positive effects on quality benefits or outcome (productivity, profitability, competitive position, reduce customer complaints, cost reduction, reduce rework level, reduces scrap level, stay in business) in services sector of telecom industry of Pakistan. Benchmarking also plays a significant role in the development of organizations. In addition to the research data, findings from different field studies and other research works have further supported conclusion drawn from this research, that TQM practices have positive effect on organizational development. The findings based on this empirical research would be useful to both decision makers and researchers.

Indoor radon levels were measured in four seasons throughout 2013 in public hospitals for Iraqi Kurdistan, using a passive technique CR-39 nuclear track detectors. Thus, the highest and lowest values of rate indoor radon were in winter (105.3 ± 17.20 Bq/m3) and summer (39.92 ± 8.28 Bq/m3) season, respectively. This different value depended for ventilation rate, building material and geological formation. According to the estimation risk factor, the radon induced lung cancer risks for public hospitals in selected locations was varied from 2.7 ± 0.08 to 11.16 ± 1.94 per million people. The highest and lowest values of annual effective dose were recorded in winter and summer seasons, respectively.

A time series database is a collection of data that are generated in series as time goes on and constitutes a large portion of data stored in computers like stock-price movements, weather data, bio-medical measurements, video data etc., Two time sequences of same length are said to be similar if the Euclidean distance is less or equal to a given threshold. The main issue of similarity search in time series databases is to improve the search performance since time sequences are usually of high dimension. So it is important to reduce the search space for efficient processing of similarity search in large time series databases. We have used Adaptive Framework for the data reduction purpose which improves the search performance in Recent-Biased time series databases. We have applied a set of linear transformations on the reduced sequence that can be used as the basis for similarity queries on time series data. We have also formalized the intuitive notions of exact and approximate similarity in time series data. Our experiments show that the performance of this method is competitive to that of processing ordinary queries using the index and much faster than sequential scanning.
