MANETs are self-organizing, infrastructure less ad-hoc networks with many challenges like low power, limited storage and limited processing devices. Among all the parameters that affect the network efficiency accuracy, scalability, and power consumption are main challenges in the routing of Mobile ad-hoc networks. The network lifetime is dependent on the power efficiency of the nodes in the network. The protocols have to provide the energy efficient route through intermediate nodes in the network. The trust based routing approach is one of the best mechanisms to establish an energy efficient route between source and destination. In this paper we first propose the family relationship based trust model and then propose a new energy efficient trust based routing protocol to reduce the routing overhead, delay and provides better packet delivery ratio that performs better than the existing routing protocols. © 2016 Institute of Advanced Engineering and Science.

In this paper the different topologies of one bit full adders including the most interesting of one proposed is analysed and compared for peak leakage,average leakage, peak power and average power. The investigation carried out with properly defined simulation runs on a cadence environment using 45 nm technology. The proposed 10 Transistor full adder has consumed 57% of average power of conventional CMOS logic circuit with 28 transistors. Where as in average leakage it has consumed 67% of average leakage power of conventional CMOS with 28 Transistors. The peak leakage and peak power of proposed 10 Transistors are 67% and 70% respectively of conventional 28 Transistors CMOS logic. The proposed full adder has only 10 Transistors.This saves silicon area. © 2016 IEEE.

Text clustering is an unsupervised process forming its basis solely on finding the similarity relationship between documents with the output as a set of clusters [14]. In this research, a commonality measure is defined to find commonality between two text files which is used as a similarity measure. The main idea is to apply any existing frequent item finding algorithm such as apriori or fp-tree to the initial set of text files to reduce the dimension of the input text files. A document feature vector is formed for all the documents. Then a vector is formed for all the static text input files. The algorithm outputs a set of clusters from the initial input of text files considered. © 2014 IEEE.

This paper presents the heat transfer study of TiO2/water Nanofluids with different concentrations. Nanofluids have emerged as an exciting new class of nanotechnology based heat transfer fluids and have grown enormously in the past few years. Nanofluids increases the performance of heat exchanging devices than the conventional working fluids. In the present work, TiO2/water nanofluids with various volume concentrations of 0.1%,0.25%,0.5% and0.75% were prepared using two step method for heat transfer study. Stability, thermal conductivity and viscosity measurement was conducted using zeta potential, KD2 Pro and Brookfield Viscometer respectively. Finally, the experiment was conducted using TiO2/water nanofluids as working fluid in a tube heat exchanger to study the heat transfer performance. The experimental results show that the nusselt number increases with an increase of particle volume fraction and the nusselt number enhancement was observed to be 13.2% over the base fluid for volume concentration of 0.75%. From the experimental observations, enhancement in Nusselt number is larger than the enhancement in friction factor. © 2015 Elsevier Ltd.

Presently a day, for any sort of data, individuals rely on upon web. They utilize web indexes like Google to pursuit data over web. The inquiries must be precise that will give the data identified with client's Health Care. Be that as it may, there is tremendous measure of data on the web as it's hard to get the significant data effortlessly. If there should arise an occurrence of inquiries on right prescription, individuals for the most part have their own particular inclinations. Wellbeing experts require the adaptability of unstructured content to express their conclusions and treatment systems. In this manner, the vicinity of unstructured content is inescapable, be that as it may, for information mining, data frameworks are obliged to change over the unstructured content to an organized representation for examination. Additionally the human advancement where individuals live will have sway on the quantity of decisions of prescription. So the proposed strategy will be utilized to prescribe best medication and nourishment to the clients or patients. These proposals are in view of the positioning of things and nourishments. The trial results give better exactness contrasted with existing strategies. © 2015 IEEE.

In order to utilize the existing transmission line to its full capacity Flexible AC Transmission system (FACTS) are used. The power flow control is effective if all the elements of the transmission line must be varied simultaneously or individually. To achieve this, the key appropriate FACTS device is Unified Power Flow controller (UPFC). The use of conventional controllers delays the decision making process to take suitable control action during dynamic conditions. In this paper a fuzzy logic based controller is used to generate supplementary damping signals and to control the shunt converter of IPFC. Two separate neuro-controllers are used for series converter control. Hence coordination between shunt and series converters of UPFC is achieved. The results in MATLAB environment will explain the performance of UPFC during step change of real and reactive powers. © 2015 IEEE.

Nanofiltration (NF) and reverse osmosis (RO) are well-established processes for desalination of sea and ground water besides treatment of industrial effluents. Pharmaceutical effluents usually contain organic and inorganic waste materials that contribute to total dissolved solids (TDS), chemical oxygen demand (COD) and biochemical oxygen demand (BOD), rendering the mode of treatment highly challenging. In the present investigation, performance of hydrophilized polyamide (HPA-250) NF and thin film composite (TFC) polyamide RO membranes has been studied for the treatment of pharmaceutical effluent condensate. Effect of applied pressure on separation performance on NF/RO membranes was investigated for both non-aerated (Feed A) and aerated (Feed B) condensates. Influence of concentration polarization and fouling on membrane performance parameters such as flux, water recovery and rejection was evaluated as a function of time. A comparative study on treatment of aerated and non-aerated feed samples was carried out with respect to flux and rejection of TDS, COD and BOD. At a constant feed pressure of 10.34. bar, %rejection of TDS was found to be 78.14 for Feed B and 75.24 for Feed A in NF process whereas the corresponding values for RO were 95.30% and 91.76%. COD removal efficiencies in the same order were observed to be 94.30% and 93.09% for NF and 99.50% and 98.33% for RO. Design and economic estimation of commercial NF/RO systems for processing of 1000. L/h pharmaceutical condensate was carried out. NF process was found to more economical than RO due to advantage of greater flux leading to requirement of lower operating pressures. © 2013 Taiwan Institute of Chemical Engineers.

With the increasing shortage in fossil fuels, and pollution problems renewable energy has become an important energy source. Comparing the all renewable energy sources wind energy is one of the most economical energy sources. In present generating units above 1 MW, variable speed concepts are usually applied that are either based on doubly fed induction generators (DFIG) or Permanent magnet Synchronous generator (PMSG) are mostly used in Wind Energy Conversion Systems (WECS). This paper discusses about the implementation of matrix converter for wind-energy conversion System employing permanent magnet synchronous generator (PMSG). The MATLAB/SIMULINK simulation software are used for simulation. © 2013 IEEE.
