In this Paper, We examine Intuitionistic Fuzzy Game Theory problem in which cost co-efficients are triangular and trapezoidal intuitionistic fuzzy numbers. In conventional game theory problem, cost is always certain. This paper develops an approach to solve an intuitionistic fuzzy games where cost is not deterministic numbers but imprecise ones. Here, the elements of the costs (profits) matrix of the games are triangular and trapezoidal intuitionistic fuzzy numbers. Then its membership and non-membership functions are defined. A ranking technique is used to compare the intuitionistic fuzzy numbers so that Dominance property in Intuitionistic Fuzzy Games may be applied and later Dominance property in Intuitionistic Fuzzy Oddments Method is used to solve the intuitionistic fuzzy games. Numerical examples show that an intuitionistic fuzzy ranking technique offers an effective tool for handling an intuitionistic fuzzy games. © Springer Science+Business Media Singapore 2016.

Air pollution is a basic problem nowadays and it requires special concern. In India, the air pollution is a growing problem because of the enhanced anthropogenic activities such as burning fossil fuels involving industrial processes and motor vehicles. We study airborne dust particles collected at the height of 7 m in roadside and land area from thirty-eight cities in the state of Tamil Nadu. The collection involves a total of 111 samples concerning vehicular, industrial and residential areas, and allows us to assess the spatial distribution of magnetic particles produced and emitted on a short period of time (about one month). Magnetic properties of these air suspended particles were determined by techniques of environmental magnetism, revealing the presence of magnetite and hematite. We found the overall average of mass-specific magnetic susceptibility χ of 589.0 × 10−8 m3 kg−1 and saturation of remanent magnetization SIRM of 68.1 × 10−3 A m2 kg−1; as well as χ and SIRM values higher than 900.0 × 10−8 m3 kg−1 and 700.0 × 10−3 A m2 kg−1, respectively, corresponding to the most impacted zones in industrial/vehicular areas and in cities located in the central/eastern region respectively (e.g.: Hosur, Krishnagiri, Salem, Dharapuram, Ranipet, Ayanavaram, Cuddalore and Chidambaram). We analyzed the relationship between magnetic parameters, between areas and possible grouping of cities using multivariate statistical analysis. The SEM-EDS observations and grain size estimations reveal the presence of trace elements (Sb, Zn, Co, Ni, As and V) and fine particles (1–5 μm) that can be inhaled and therefore are dangerous to human health. © 2016 Turkish National Committee for Air Pollution Research and Control

One of the most attractive techniques used to improve the data retrieval performance in wireless mobile environment is caching. In Mobile ad hoc networks (MANETs), updating of cached data item needs to be done frequently due to the high mobility of the nodes. This leads to additional overhead and delay. In this paper, we propose to develop a cluster based cooperative caching technique based on mobility prediction to handle mobile disconnections and to reduce the overhead. The network is divided into clusters and the selection of cluster head is done based on the power level and connectivity. The details of the cached data items in the cluster and its adjacent clusters are maintained in the local cache table (LCT) and the Global cache table (GCT). After predicting the movement of its cluster members using Hidden Markov Model (HMM), the cluster head updates the LCT and GCT to maintain consistency thus the reducing the delay and frequent overheads in cache updation. From our simulation results we show that this caching technique reduces the delay by 63% and 27% when compared with the existing technique, for increasing number of nodes and speed respectively. Similarly it reduces the overhead by 45% and 29% for increasing number of nodes and speed respectively. © EuroJournals Publishing, Inc. 2012.

Sentiment arrangement is a paramount assignment in ordinary life. Clients express their opinion about their thing, films and so on. All the site page contains surveys that are given by clients communicating distinctive extremity i.e. positive or negative. It is valuable for both the maker and purchaser to realize what individuals think about the specific item or administrations focused around their reviews. Programmed file gathering is the task of ordering the surveys focused around the sentiment communicated by the audits. Sentiment is communicated diversely in distinctive domains. The information prepared on one domain can't be connected to the information prepared on an alternate domain. The cross domain sentiment grouping conquers these issues by making thesaurus for labeled information on the target domain and unlabeled information from source and target domains. Sentiment affectability is attained by making thesaurus. We conduct a far reaching observational investigation of the proposed strategy on single and multisource domain adaption, unsupervised and supervised domain adaption, and different comparability measures for making the sentiment sensitive thesaurus. © Research India Publications.

The abstract of this paper explains the presence of minerals in air which causes great concern regarding public health issues. The spectroscopic investigation of air dust particles of several samples in various locations in the state of Tamilnadu, India is reported. Qualitative analyses were carried out to determine the major and minor constituent minerals present in the samples based on the FTIR, XRD absorption peaks. This study also identified the minerals like quartz, asbestos, kaolinite, calcite, hematite, montmorillonite, nacrite and several other trace minerals in the air dust particles. The presents of quartz is mainly found in all the samples invariably. Hence the percentage of quartz and its crystalline nature were determined with the help of extinction co-efficient and crystallinity index respectively. The shape and size of the particulates are studied with SEM analysis. © 2014 Elsevier B.V. All rights reserved.

Concrete structures are deteriorated due to environment conditions. Strengthening of existing structures are the most important challenges in the Civil Engineering. Recently, Basalt fibre are used for strengthening due to various advantages such as good range of thermal performance, high tensile strength, resistance to acids, good electromagnetic properties, inert nature, resistance to corrosion. This study presents the flexural behavior of Unidirectional and Multidirectional Basalt Fibre Reinforced Polymer (BFRP) composites, strengthened with reinforced concrete beams. For flexural strengthening of reinforced concrete beams, totally nine beams of size 100×160×1700 mm were cast using M20 grade concrete and tested under two point loading. One beam was used as reference and four beams were strengthened with uni directional BFRP composite and four beams were strengthened with Multi directional BFRP composite at bottom surface alone in the form of single layer, double layers, three layers and four layers, respectively. Test result indicates, the first crack load of strengthened beams with unidirectional BFRP increased by 14.98 to 66.79% when compared to reference beam and multi layered BFRP increased by 6.79 to 47.98%. The ultimate load carrying capacity increases from 8.6 to 34.6% in unidirectional BFRP and 5.66 to 20% in multidirectional BFRP when compared to reference beam. This study presents the enhancement in the structural behavior of BFRP strengthened beams compared with reference beam. © Maxwell Scientific Organization, 2015.

This work presents the effect of particles density on holdup mass and heat transfer rate in solid cyclone heat exchanger. Performance of cyclone heat exchanger mainly depends on operational parameters such as inlet air velocity, temperature; solid particles feed rate and density. Present work studies the effect of particles density by varying inlet air velocity and temperature. Four different solid particles (Sulfur, Dolomite, Steel and Copper) density ranges from 2050 to 8950 kg/m3 which are fed at 0.5 g/s flow rate and inlet air velocity ranging from 4.6 to 24.2 m/s at three inlet air temperatures 373, 473 and 573 K. Experimental setup was built for stairmand high efficiency cyclone. Good agreement was found between experimental and literature pressure drop. Results conclude that holdup mass and heat transfer rate increases 0.5-1.5% and 82-86% with decrease in density particles respectively. Increase in inlet air velocity, holdup mass and heat transfer rate raises 3.2-6% and 4-6.7% respectively for all particles at all inlet air temperatures. © 2006-2016 Asian Research Publishing Network (ARPN).

Effect of mass flow rate of inlet gas on holdup mass in a high efficiency cyclone has been performed. Cyclone as heat transfer equipment may be used for solidification, drying, water removal, sublimation, solvent recovery, chemical reaction and oxidation. In all cases, performance of cyclone depends on the surface area of the solid particles inside the cyclone. The holdup varies with the variation in operating parameters. This proposed work will present an effect of mass flow rate of inlet gas on cyclone heat exchanger and calculation of holdup mass by varying the solid feed rate, mass flow rate of inlet gas and diameter of the particle. © (2014) Trans Tech Publications, Switzerland.

The thermal behaviour of tetrakis(2,2,6,6-tetramethyl-3,5-heptanedionato) zirconium(IV), [Zr(tmhd)4] was investigated by nonisothermal and isothermal thermogravimetric methods in a high pure nitrogen atmosphere. The influence of the heating rate in dynamic measurements (6, 8, 10, and 12°C/min) on activation energy was also studied. The nonisothermal sublimation activation energy values determined following the procedures of Arrhenius, Coats and Redfern, Kissinger, and Flynn-Wall yielded 76 ± 5, 92 ± 2, 81 ± 8, and 72 ± 7 kJ/mol, respectively, and the isothermal sublimation activation energy was found to be 87 ± 4 kJ/mol over the temperature range of 411-462 K. Different reaction mechanisms were used to compare with this value. Analysis of the experimental results suggested that the actual reaction mechanism was an R n deceleration type. © 2013 T. S.
