Nano filler dispersed conjugated polymer composites have zooming significance on account of their synergistic and hybrid attributes attained from the extensive gamut of modules. Pure and 2.5 mole % TiO2 nanoparticle dispersed PVAxPOM(1-x) polymer composite films for various x values (x= 0 to 1 insteps of 0.25) were casted by means of simple solution casting technique (SSCT). The casted films were characterized by structurally by X-ray diffraction method. Optical behaviour of the pure and TiO2 dispersed films were tested using UV-Vis absorbance spectroscopy. The dielectric measurements were performed using an impedance analyzer (Agilent 4284 A LCR meter) covering a frequency range from 100 to 1×106 Hz. © 2017, Inst Materials Physics.

Wireless sensor networks (WSN) used to watch changes in an environment of a given field. Coverage, communication and connectivity of the network are the most fundamental challenges in WSN. Sensor nodes are mostly battery operated and expected to work for a longer time without replacing the batteries. The measure of the efficiency of a network usually defined about how efficient in sensing the given physical ambience. Energy efficient coverage of sensor nodes in Wireless sensor network is essential and has lots of scopes in the area for research. Connectivity can defined the ability of the sensor to reach the data sink. Finding a best node deployment policy that offers high degree of coverage with network connectivity is quite demanding. In this paper we are discussing about energy-efficient coverage with an innovative node topology. © 2016 IEEE.

This paper deals with the problem of delay-dependent global robust asymptotic stability of uncertain switched Hopfield neural networks (USHNNs) with discrete interval and distributed time-varying delays and time delay in the leakage term. Some Lyapunov--Krasovskii functionals are constructed and the linear matrix inequality (LMI) approach are employed to derive some delay-dependent global robust stability criteria which guarantee the global robust asymptotic stability of the equilibrium point for all admissible parametric uncertainties. The proposed results that do not require the boundedness, differentiability, and monotonicity of the activation functions. Moreover, the stability behavior of USHNNs is very sensitive to the time delay in the leakage term. It can be easily checked via the LMI control toolbox in Matlab. In the absence of leakage delay, the results obtained are also new results. Finally, nine numerical examples are given to show the effectiveness of the proposed results. © 2011 Springer-Verlag London Limited.

In this work, the vibrational spectral analysis was carried out by using Raman and infrared spectroscopy in the range 100-4000 cm-1 and 50-4000 cm-1, respectively, for the title molecules. The molecular structure, fundamental vibrational frequencies and intensity of the vibrational bands are interpreted with the aid of structure optimizations and normal coordinate force field calculations based on Hartee Fock (HF) and density functional theory (DFT) method and different basis sets combination. The complete vibrational assignments of wavenumbers were made on the basis of potential energy distribution (PED). The scaled B3LYP/6-311++G(d,p) results show the best agreement with the experimental values over the other methods. The calculated HOMO and LUMO energies show that charge transfer occurs within molecule. The influences of bromine atom and methyl group on the geometry of benzene and its normal modes of vibrations have also been discussed. The results of the calculations were applied to simulated spectra of the title compounds, which show excellent agreement with observed spectra. © 2012 Elsevier B.V. All rights reserved.

Hyperlipidemia is an associated complication of diabetes mellitus. The association of hyperglycemia with an alteration of lipid parameters presents a major risk for cardiovascular complications in diabetes. The present study was designed to examine the antihyperlipidemic effect of S-allylcysteine (SAC) in STZ induced diabetic rats. The levels of blood glucose, cholesterol (TC), triglycerides (TG), free fatty acids, phospholipids and fatty acid composition were estimated in the liver and kidneys of control and experimental groups of rats. Oral administration of SAC at a dose of 150. mg/kg bodyweight per day to STZ-induced diabetic rats for a period of 45 days resulted in a significant reduction in fasting blood glucose, TC, TG, free fatty acids, phospholipids, LDL-C, VLDL-C and elevation of HDL-C in comparison with diabetic control group. Oral administration of SAC to diabetic rats also decreased the concentrations of fatty acids, viz., palmitic, stearic (16:1), and oleic acid (18:1), whereas linolenic (18:3) and arachidonic acid (20:4) were elevated. The antihyperlipidemic effect of SAC was compared with glyclazide; a well-known antihyperglycemic drug. The result of the present study indicates that SAC showed an antihyperlipidemic effect in addition to its antidiabetic effect in experimental diabetes. © 2010 Elsevier GmbH.

Anaphora is one of the mostly attractive phenomenons in computational linguistics for resolving anaphora with preceding and succeeding referent. The ability to perform Anaphora Resolution is important in NLP application. Traditional research focus on resolving particular type of anaphora only, no one integrates methods or procedure to resolve all type of anaphora. In this paper, we identify all type of anaphora with layered or step by step approach so that everyone utilize anaphora paradigm in their application. We proposed a new enhanced framework in which all required rules of resolution are perform, the new system extract most accuracy antecedents of anaphora. © 2013 IEEE.

Imaging spectroscopy is an emerging and versatile technique that finds applications in diverse fields concerned with remote identification, discrimination and mapping of materials. The large amount of spectral data produced by hyperspectral imaging necessitates the development of automated techniques that convert imagery directly into thematic maps. Spectral library search method, a method of choice for organic compound identification by the mass spectroscopy, has caught the attention of researchers as one of the appropriate methods for an efficient exploitation of high quality spectral data available from the hyperspectral imaging systems. Given the apparent increase in the number of papers appearing on the subject as well as the variety of methods proposed, it is reasonable to say that the field of automated interpretation of reflectance spectral data has passed its infancy now gaining important space in the scientific community. We present an overall view of the literature relevant to the development of library search method, the various search algorithms and systems available in the purview for developing an automated hyperspectral data analysis system for material identification. © 2013 Copyright Taylor and Francis Group, LLC.

Nutritional requirements at optimal level can contribute considerably to the production cost and the bioprocess economics. Media optimization using response surface methodology is one of the used methods to ameliorate the bioprocess economics. In the present study, Amylase production by Marine actinomycetes Streptomyces gancidicus_ASD was effectively enhanced by response surface methodology. An OFAT (one factor at a time) based statistical screening procedure was adopted to determine the most important factor affecting amylase production. The variables are screened and results show that sucrose and Beef extract concentrations influence the most as carbon and nitrogen source on amylase production respectively. A Central Composite Design was conducted to optimize the four selected factors. Statistical analyses of the data of model fitting were done by using Design expert 10.0(stat-Ease). Results show a maximum predicted Amylase yield of 11460.34 IU/ml when using 1.05 % sucrose, 0.608 % Beef extract, 7.1 pH and 40.35 °C Temperature. The predicted value is approximately 1.24 fold much higher than the original production (9248 IU/mL) determined by the conventional onefactor- at-a-time optimization method which can be applied in bioprocess for increased amylase yield.
