The Fourier transform infrared (FTIR) and FT-Raman spectra of 8-chloro-1-methyl-6-phenyl-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine (8C1M6PB) have been recorded in the range of 4000-400 and 4000-100 cm -1, respectively. A detailed interpretation of the vibrational spectra of this compound has been made on the basis of the calculated potential energy distribution (PED). The equilibrium geometries, harmonic frequencies, infrared intensities and Raman scattering activities were calculated by Hartree-Fock (HF) and density functional B3LYP method with the 6-31G (d,p) basis set. The vibrational frequencies were calculated in all these methods and were compared with the experimental frequencies which yield good agreement between observed and calculated frequencies. The first order hyperpolarizability (βtotal) of this molecular system and related properties (β, μ, and Δα) are calculated using HF/6-31G (d,p) and B3LYP/6-31G(d,p) methods based on the finite-field approach. The calculated Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) energies show that charge transfer occurs in the molecule. Stability of the molecule arising from hyper conjugative interactions, charge delocalization has been analyzed using natural bond orbital (NBO) analysis. Conformation analysis was carried for 8C1M6PB by Potential energy surface scan to find all possible conformers with B3LYP method using 6-31G (d,p) basis set. The entropy of the title compound is also performed at HF/6-31G (d,p) and B3LYP/6-31G(d,p) levels of theory. In addition, the thermodynamic properties of the compound were calculated at different temperatures and corresponding relations between the properties and temperature were also studied. © 2013 Elsevier B.V.

AISI 1040 is a high quality, unalloyed medium carbon steel usually good ductility with resistance to wear. Tool wear (TW) and surface roughness (SR) are mostly considered as demanding phases, and thus causing poor results in machining operations. Optimization of cutting parameter is more crucial at this condition for improving the quality of the product. Taguchi method is the method to achieve a robust experimental design in the study of product quality is an important issue. The best factors/levels combination with lowest societal cost solution to achieve customers requirements look by Taguchi method. Various cutting speed, feed and depth of cut are taken as parameters. In this study single response optimization was performed in computer numerically controlled (CNC) turning AISI1040 with TiCN/TiN coated cutting tool under dry condition using Taguchi Techniques with the objective of minimization SR and TW. Analysis of variance (ANOVA) was used for identifying the significant parameters affecting the responses. © (2014) Trans Tech Publications, Switzerland.

Cytogenetic is a branch of genetics that is concerned with the study of the structure and function of the cell, especially the chromosomes. The chromosomal identification is of prime importance to geneticist for diagnosing various abnormalities. The existing system is developed to classify the chromosomes based on pixel distribution, centromere index and band patterns using artificial neural network techniques. The accuracy of classification is lowered particularly in sub group 'C'. In this paper we propose a technique where the input images of the unpaired well spread chromosomes are obtained from the electron microscope. Initially noise is removed and edges are detected. Then, each object is extracted from the input image, rotated to align vertically and cropped. Then, the features of each chromosome like major axis length, Area and histogram are analysed and sorted in descending order to perform classification. Then based on the number of objects, the numerical abnormality like monosomy and trisomy are detected. Thus the system is fully automated for well-spread images and semi-automated for images with overlapped chromosomes.

In Embedded system based applications, the evolution of multicore architectures offers many performance enhancements like speed, concurrency, real-time implementation support etc. However, design issues like critical section handling, selecting optimal number of threads, racing condition avoidance, concurrent tasks handling etc. needs to be addressed. In this work, these issues are implemented for multicore architecture using openMP tool. Barrier region limitations are removed to exploit concurrency and demonstrated applications include are, (i) array filling multitasking (ii) sorting of number, and (iii) sorting of strings. In all the above examples, the performance of multicore is enhanced compared to single core. © 2005 - 2014 JATIT & LLS. All rights reserved.

In day today's relevance, it is mandatory to devise the usage of diesel in an economic and environmentally benevolent way. In the present scenario, the very low combustion efficiency of compression ignition engine leads to poor performance of the engine and emission of incomplete combustion by-products. Hence it was planned to increase the combustion efficiency, and thereby to increase the performance and to reduce the exhaust emission by adding n-propanol at different proportions like 2%, 4%, 6%, 8% and 10% by volume with diesel. The performance, combustion and emission characteristics observed while using blended fuels were analyzed and compared with that of diesel as fuel without any additives. The performance analysis revealed that, at full load, the brake thermal efficiency is increases by 11.78% for 10% n-propanol blended with diesel. The emission test reported that, the CO and NOx emissions decreased by 44.12% and 9.33% respectively at full load.

In India groundwater is the major source of drinking water for millions of rural and urban families. Groundwater is generally less susceptible to contamination and pollution when compared to surface water bodies. Also, the natural impurities in rainwater, which replenishes groundwater systems, get removed while infiltrating through soil strata. In India, where groundwater is used intensively for irrigation and industrial purposes, a variety of land and water -based human activities are causing pollution of this precious resource. Tirupur, Tamilnadu is one of the largest contributors to India's textile output and has 5450 units in this business. But this increasing commercialization has an impact on its environment especially on groundwater. It is facing a severe shortage of potable water. The dyeing and bleaching units are pumping out large quantities of effluents, as a result the ground water and water bodies have degraded up to a large extent. In Tirupur 700 dyeing units discharge 100 million litres of untreated effluents every day. As a result, sludge has deposited largely in NoyyalRiver, a tributary of Cauvery. The Noyyal River has been associated with severe water qualityproblems and the practice of discharging untreated industrial waste into the river course is alarming. The quality of groundwater in Tirupur regions hasbeen deteriorating rapidly during the last decade. In this paper efforts have been made for assessing the quality of groundwater, water samples from the study area were collected and analyzed for physicochemical parameters. Also suggest the prevention of groundwater from textile industries effluents and remedial strategies for sustainable development. Copyright © EM International.

Water is the most precious asset in this world; water shortage has been recognized as one of the key issues facing many countries. The water demand is still increasing due to population growth and higher standard of living. The use of domestic rainwater harvesting and greywater treatment systems has potential to supply nearly 20 to 30 percent of domestic water in India households. Wastewater is an immense resource which could have significant applications in regions of water scarcity. Greywater has particular advantages in that it is a large source with a low organic content. This study is aims in greywater recycling technologies, applications. It also suggests simple technologies that sand filters have been shown to achieve only a limited treatment of the greywater whereas membranes were reported to provide good removal of the solids. Disinfection of various microorganisms is achieved by chlorination. The best overall performances were observed within the schemes combining different types of treatment to ensure effective treatment of all the fractions. It has been estimated that water savings in the range of 18-29 percent for an average household could be achieved by reusing greywater. Domestic rainwater harvesting and greywater treatment systems can play a very important role in future water management and prospective sustainable living in India. Copyright © EM International.

Wi-Fi-based positioning system (WPS) is used where GPS is inadequate due to various causes including multipath and signal blockage indoors. Such systems include indoor positioning systems. The advantage of choosing Wi-Fi for a location based service is its high compatibility and frequency of availability. The majority of today’s smart phones also have Wi-Fi connectivity. Newer revisions of Wi-Fi broadcast at the 2.4 GHz frequency, allowing for signals to more easily travel through obstructions like doors and walls. Unlike other wireless technologies such as Bluetooth, Wi-Fi incorporates signal strength functions into all the firmware drivers and Application Programming Interfaces (APIs) which are defined by the manufacturers and backed by IEEE.2 This feature will provide a large benefit when using Wi-Fi to determine a location based on signal strength triangulation. The localization technique used for positioning with wireless access points is based on measuring the intensity of the received signal strength (RSSI). Typical parameters useful to geo-locating the Wi-Fi hotspot or wireless access point include the SSID and the MAC address of the access point. The accuracy depends on the number of positions that have been entered into the database. The possible signal fluctuations that may occur can increase errors and inaccuracies in the path of the user. To minimize fluctuations in the received signal, there are certain techniques that can be applied to filter the noise. The Mobile Nodes will have featured Wi-Fi capabilities and the processing power to deliver accurate results. The Nodes will scan all known access points that in range and determine the signal strength in dBm (or dBmW) and get there respective MAC address. The access point’s MAC address is compared against a database of known access point locations. All of the quantified location coordinates are saved and the location of the each Node is obtained. The more available access points, the more accurate the location reading will be. We are using only 3 access points to obtain the (x,y) coordinate values/location of the mobile device. The calculated position will be displayed in graphical format. © 2005 - 2015 JATIT & LLS. All rights reserved.
