In day today's applications, it is obligatory to devise the usage of diesel in an economic and environmentally benign way. The present work was aimed at studying the performance, emission and combustion characteristics of a four-stroke diesel engine by adding n-pentane at different proportions such as 2%, 4%, 6%, 8% and 10% by volume with diesel. The performance, combustion and emission characteristics obtained from the experiment revealed that the addition of n-pentane augments the brake thermal efficiency of the engine. At full load, the brake thermal efficiency increased by 3.17% for an addition of 6% n-pentane, 4.31% for an addition of 8% n-pentane and 6.36% for an addition of 10% n-pentane. From the emission test, it was concluded that at full load, the NOx emission decreased by 8.67% for an addition of 6% n-pentane, 17.43% for an addition of 8% n-pentane and 18.09% for an addition of 10% n-pentane. © 2014 Taylor & Francis.


In today's application, it is obligatory to formulate the use of diesel in an environmentally benevolent manner. So, in this experimental study, an attempt was made to increase the performance and reduce the exhaust emission by blending various alcohols such as n-propanol and n-butanol separately at different proportions like 4% and 8% by volume with diesel, also to compare the effect of blending n-propanol and n-butanol separately with diesel, on performance, combustion and emission characteristics. The performance, combustion and emission characteristics observed while using blended fuels were analyzed and compared with that of diesel as fuel without adding alcohols. From the performance analysis, it was reported that, at 80% load, the brake thermal efficiency was increased by 1.579%, 7.635%, 8.917% and 10.518% for the addition of 4% n-propanol, 8% n-propanol, 4% n-butanol and 8% n-butanol with diesel respectively. The emission test concluded that, the smoke density was increased by 12.891%, 5.078%, 11.338% and 14.063% for the addition of 4% n-propanol, 8% n-propanol, 4% n-butanol and 8% n-butanol with diesel respectively. The NOx emission was decreased by 6.098%, 19.665%, 11.585% and 14.329% for the addition of 4% n-propanol, 8% n-propanol, 4% n-butanol and 8% n-butanol with diesel respectively. © 2014 Elsevier Ltd.

Kinetic investigation in 2,2'-bipyridyl catalyzed oxidation of some cyclanols(cyclopentanol, cyclohexanol, cycloheptanol, cyclooctanol) by quinolinium bromochromate (QBC) in 60 % aqueous acetic acid medium in presence of mercuric (II) acetate as a scavenger have been studied. The reaction exhibits a first order rate dependence with respect to oxidant quinolinium bromochromate (QBC) and perchloric acid while it is fractional order in cyclanols and 2,2'-bipyridyl. The variation of ionic strength, Hg(OAc)2 and acrylonitrile have insignificant effect on reaction rate. Effect of varying dielectric constant of medium on the reaction rate has been studied. Activation parameters have been evaluated from Eyring plots by studying the reaction at different temperature. The rate law has been derived on the basis of obtained data.

Monitoring and diagnosis of patients without directly accessing them is very important in medical application of wireless sensor network. But, collecting, transferring and maintaining of data is challenging task. So, there is an immense need to handle all these information in a quickly and effectively way. In this paper, we utilize agents in different processes such as, data collection from the different sensors, transferring, storing to the appropriate servers, classifying the data and give the prescriptions to the patients. In this paper, we organize the proposed architecture in three layers, the first one is body area network layer which helps to store the medical information get from the body sensors of the patients, the second layer is conveyer layer which helps to transfer the medical information one layer to another layer and the final one is data analyze layer which helps to store, analyze medical data also it gives the exact prescriptions for the medical information of the patient. Finally the, remedy for the medical information is send through the conveyer layer. Finally the experimentation is made with the number of patient's rate of transferring the medical data and our implementation is done with the help of JADE and JNS. © 2005 - 2014 JATIT & LLS.

The robotics casts a vital part in day-to-day life. A large majority of the robots are employed in industries, factories and in our neighbourhood ecosystem. In this regard, diverse kinds of robots are employed for specific purposes. Standing out amongst them are the hexapod robots, endowed with six legs or wheels to move about in the surroundings in a consistent manner. As they have to move quickly in the atmosphere overcoming the roadblocks so as to arrive at the target with the least possible time-frame, we have come up with an innovative technique through this document. The epoch-making technique lends a helping hand to boost the momentum of the hexapod robot thus enabling the realization of the target with a short span of time. For the purpose, we have elegantly employed the Fuzzy rule base technique, to fine-tune the efficiency in performance of the so as to exploit him to the maximum in this sophisticated world of innovation. The milestone methods find it elegantly executed in the working platform of the mighty MATLAB and the outcomes are subjected to deep assessment. © 2015 Springer Science+Business Media New York

A beam with a number of regular openings in its web is called a castellated beam. With the development of design optimization and advancement in construction, castellated beams gain its advantage due to its increased depth of section without any additional weight. Castellated beam has some limitations also, stress concentration occurs near the perforations and the shear carrying capacity is reduced. The shear carrying capacity can be increased by stiffening the web at points of concentrated loads and reactions. Hence, to increase the shear strength of the castellated beam and also to reduce the deflection, shear stiffeners are introduced along the web opening and also on the web along the shear zone [5]. In this paper steel I sections ISMB 150 and ISMB 200 is selected and castellated beams are fabricated, such that depth of the castellated beam is 1.5 times more than the original depth. Experimental test is carried out to predict the failure modes of castellated beam with the effect of diagonal and vertical stiffeners. © Research India Publications.

Phase change materials (PCMs) with their phenomenal phase changing behavior hold a key for many developments in renewable energy and engineering systems for sustainable future. PCM which can store and release heat energy over a temperature range has become an eminent candidate for many engineering applications that includes thermal, civil, electronics and textile. In modern days, Nano-PCMs have gained much attention of the engineers in utilizing them for thermal energy storage systems, for cooling microelectronic systems, for space heating or cooling in modern buildings and also in smart textiles for human comfort. Contribution of Nano-PCM based energy systems in energy savings and reduction of global gas emission is of interest now. This review provides an outlook of various types of PCM, choices of nanomaterial for incorporation and applications of nanomaterial incorporated PCMs. The most common types of PCM used are water, paraffin, hydrated salts and bio based PCM. Despite their high latent heat storage advantage, their low thermal property calls for the incorporation of nanomaterials. Nanomaterials with their high surface to volume ratio tune the thermal properties of the base PCM. Nanomaterials used for incorporation in PCM include Al, Cu, SiO2, TiO2, Carbon nanotubes (CNT), Carbon nanofibers (CNF), Al2O3, NaOH KOH etc. © 2016 Eastern Macedonia and Thrace Institute of Technology.

This paper is focused on the investigation behavior of shear strength of castellated beam with and without stiffeners. Castellated beams are steel beams with web openings and they gain its advantage due to its increased depth of section without any additional weight. However one consequence is the presence of web opening which leads to various local effects like shear and deformation. In this paper steel I section ISMB 150 and ISMB 200 is selected and castellated beams are fabricated such that depth of the beam is 1.5 times greater than the original depth. The beam is analysed using Finite Element Analysis (ANSYS 14). Two point loads is applied and stress distribution is studied. Stress concentration increases at the hole corners along the shear zone and at load application point. Deflection of the beam with and without stiffeners is studied. And stiffeners are introduced diagonally on the web opening along the shear zone, and in the other case stiffeners are provided on the solid portion of the web along the shear zone. From the results obtained from ANSYS14 it is concluded that shear strength of castellated beam can be improved by providing diagonal stiffeners along the web opening. Also it is concluded that stiffeners provided on the opening of the web is more effective than stiffeners provided on the solid portion of the web.

The kinetics of oxidation of a few aliphatic primary alcohols with 1-chlorobenzimidazole (CBI) was studied in aqueous acetic acid medium. The reactions were found to be first order each with respect to the concentrations of CBI and alcohol. The added HClO4 increases the rate and the order in HClO4 was found to be fractional. The reactions were catalyzed by NaCl and fractional order dependence was observed. The ionic strength had negligible influence on the rate. The reaction rates increase with decrease in dielectric constant of acetic acid. Addition of benzimidazole, one of the products does not affect the rate. Effect of temperature on the reaction rates was studied at different temperatures and the various activation and thermodynamic parameters were evaluated. The rate constants show good correlation with Taft-Pavelich Dual substituent parameter model (DSP). Product analysis shows the formation of aldehydes as major products of oxidation of aliphatic primary alcohols. CBIH+ has been postulated as the reactive oxidizing species. A mechanism involving a proton transfer by water molecule has been proposed. © 2015 Walter de Gruyter Berlin/Boston.
