Multicore systems along with GPUs enabled to increase the parallelism extensively. Few compilers are enhanced to emerging issues with respect to threading and synchronization. Proper classification of algorithms and programs will benefit largely to the community of programmers to get chances for efficient parallelization. In this work we analyzed the existing species for algorithm classification, where we discuss the classification of related work and compare the amount of problems which are difficult for classification. We have selected set of algorithms which resemble in structure for various problems but perform given specific tasks. These algorithms are tested using existing tools such as Bones compiler and A-Darwin, an automatic species extraction tool. The access patterns are produced for various algorithmic kernels by running against A-Darwin and analysis is done for various code segments. We have identified that all the algorithms cannot be classified using only existing patterns and created new set of access patterns. © 2015 IEEE.

Corrosion inhibition of zinc in 0.1 M HCl by Tenofovir Disproxil Fumarate(TDF) an anti-HIV drug has been investigated by using weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy. The experimental results suggested the inhibition efficiency increases with the increase in inhibitor concentration up to 10 ppm. Polarization results revealed that TDF acts as a mixed type inhibitor. The effect of temperature on the corrosion behavior of zinc in the given temperature range from 303–333 K was studied. Adsorption of the inhibitor followed the Langmuir isotherm. Activation and thermodynamic adsorption parameters were calculated and discussed. © 2014, The Indian Institute of Metals - IIM.

Ketosulfone has been evaluated as a green corrosion inhibitor for mild steel in 1 M HCl medium by chemical and electrochemical methods. The effect of Ketosulfone on the corrosion rate was determined at various concentrations and temperature. Polarization measurements reveal that Ketosulfone acts as a mixed-type inhibitor. The adsorption of the inhibitor on the mild steel surface in acid solution was found to obey the Langmuir adsorption isotherm. The activation and thermodynamic parameters of dissolution and adsorption were calculated and discussed. Quantum chemical calculations were calculated and discussed, and it supports the results. SEM images of inhibited strips reveal the likely formation of a protective film. © 2014 American Chemical Society.

MANETs has become a broad area in wireless networks, because of its reduced deployment cost, ease of use, and deliverance from wires. MANETs uses a decentralized and infrastructure-less network, thus making the nodes to route its messages / data with the help of intermediate nodes. Routing in MANETs is carried out with the help of broadcasting schemes, among which MPR is found to be the effectual and uncomplicated scheme. The MPR scheme broadcasts its messages only to the selected MPR nodes. The selected MPR node may be any node in the network, and there are no obligatory and adequate conditions that provides assurance about the selected node’s integrity. In this paper, we have proposed a novel approach in the MPR node selection, by adding a security feature prior to the MPR node selection. We have verified the time constraints and efficiency with the help of localization techniques. Future events are also been discussed. © Springer International Publishing Switzerland 2015.

This paper presents the results of experimental studies to control the base pressure from a convergent nozzle to ascertain the effect of level of expansion on a suddenly expanded sonic flow. An active control in the form of four micro jets of 1 mm orifice diameter located at 900 intervals along a pitch circle diameter of 1.3 times the nozzle exit diameter in the base region was employed to control the base pressure. The area ratio (ratio of area of suddenly expanded duct to nozzle exit area) studied is 2.4. Experiments were conducted for nozzle pressure ratio (NPR) from 1.5 to 3, in steps of 0.5. The length-to-diameter (L/D) ratio of the enlarged duct was varied from 10 to 1, and tests were conducted for L/D 10, 8, 6, 5, 4, 3, 2 and 1. It is evident from the results that the flow field downstream of the reattachment-redevelopment is very complex. It is found that, unlike in the case passive controls, the favourable pressure gradient does not ensure augmentation of the control effectiveness for active control in the form of micro jets. To study the influence of micro jets on the quality of flow in the enlarged duct wall pressure was measured and it is found that the micro jets do not disturb the flow field in the duct. © 2014 Praise Worthy Prize S.r.l. - All rights reserved.

This article experimentally investigates the effect of spark timing on performance and emission characteristics of high-speed spark-ignition (SI) engine operated with different hydrogen–gasoline fuel blends. For this purpose, the conventional carbureted SI engine is modified into an electronically controllable engine, wherein an electronically controllable unit was used to control the ignition timings and injection duration of gasoline. The tests were conducted with different spark timings at the wide open throttle position and 3000 rpm engine speed. The experimental results demonstrated that brake mean effective pressure and engine brake thermal efficiency increased first and then decreased with the increase in spark advance. Peak cylinder pressure, temperature and heat release rate were increased until 20% hydrogen addition and with increased spark timings. NOx emissions were continuously increased with the increment in both spark timings and hydrogen addition, whereas hydrocarbon emissions were increased with spark timings but decreased with hydrogen addition. CO emissions were reduced with the increase in spark timing and hydrogen addition. © 2016 Informa UK Limited, trading as Taylor & Francis Group

Wireless sensor networks (WSNs) are on a steady rise in the current decade because of its progressions in hardware design, resource efficiency, communication and routing protocols, and other aspects. Recently, people started preferring mobile nodes in the place of static nodes, which brought mobile sensor network into focus. Location information always plays a key role in Mobile wireless sensor network (MWSN) and precise localization has always been a challenge for mobile sensor nodes. Deploying GPS receivers for each node would render network deployment cost for a dense network. The unavailability of GPS in indoor and underground environment has also put the installation of GPS into question. This makes the sensor nodes to identify its location coordinates or location reference without using GPS, and is achieved with the help of a special node that knows its location coordinates and protocols, called beacon node. This paper’s goal is to confer different localization techniques used by mobile sensor nodes to identify their location information. Problems and future issues have also been discussed. © Springer-Verlag Berlin Heidelberg 2014.

Localization is extensively used in Wireless Sensor Networks (WSNs) to identify the current location of the sensor nodes. A WSN consist of thousands of nodes that make the installation of GPS on each sensor node expensive and moreover GPS will not provide exact localization results in an indoor environment. Manually configuring location reference on each sensor node is also not possible in the case of dense network This gives rise to a problem where the sensor nodes must identify its current location without using any special hardware like GPS and without the help of manual configuration. Localization techniques make the deployment of WSNs economical. Most of the localization techniques are carried out with the help of anchor node or beacon node, which knows its present location. Based on the location information provided by the anchor node or beacon node, other nodes localize themselves. In this paper we present a succinct survey on the localization techniques used in wireless sensor networks covering its problems and research gap. © 2014 IEEE.

In the Present paper effect of angle of incidence on pitching derivatives of a delta wing with curved leading edges of a attached shock case is been studied. A Strip theory is used in which strips at different span wise location are independent. This combines with similitude to give a piston theory. From the results it is found that stiffness and damping derivatives in pitch increasing linearly up to angle of attack 25° and then non-linearity creeps in. The Present theory is valid only for attached shock case. Effects of wave reflection and viscosity have not been taken into account. Results have been obtained for hypersonic flow of perfect gases over a wide range of angle of attack and Mach number.
