With the advent of Cloud computing, the cloud has become the major service provider due to its inbuilt flexibilities and very low requirements. Effective usage of cloud can be made possible only when accurate parameters are provided during the configuration phase. But determining the appropriate parameters is not possible when migrating from web to cloud. This paper presents effective mechanisms that can be used to identify the parameter values using the data available from web logs. The framework begins from exploring and cleaning the data and proceeds by providing a simple use case of how attribute values can be extracted from the available data using clustering techniques from several dimensions. The final mapping phase also has several possibilities ranging from manual mapping to usage of machine learning algorithms and several Big Data tools. © Research India Publications. Source

A novel implantable CPW fed Apollian shaped antenna embedded into human tissue is proposed for ISM band biomedical applications. The proposed antenna is made compatible for implantation by embedding it in an alumina ceramic substrate(εr=9.8 and thickness= 0.65 mm). The proposed antenna covers the ISM band of 2.45 GHz. The radiation parameters such as return loss, xy-plane, xz-plane, and yz-plane etc., are measured and analyzed using the agilent vector network analyzer. The proposed antenna has substantial advantages, including low profile, miniaturization ability, lower return loss, better impedance matching, and high gain over conventional implanted antennas. © 2015 KIEEME.

The title compound methyl(2E)-2-{[N-(2-formylphenyl) (4-methylbenzene)sulfonamido]methyl}-3-(4-fluorophenyl) prop-2-enoate (MFMSF) has been synthesized and single crystals were grown by slow evaporation solution growth technique at room temperature. The grown crystals were characterized by FTIR, 1H NMR, 13C NMR, and single crystal X-ray diffraction. In the crystal, molecules are linked by intermolecular C-H...O hydrogen bonds forming a two-dimensional supramolecular network along [110] direction. The molecular geometry was also optimized using density functional theory (DFT/B3LYP) method with the 6-311G (d,p) basis set in ground state and compared with the experimental data. The entire vibrational assignments of wave numbers were made on the basis of potential energy distribution (PED) by VEDA 4 programme. Stability of the molecule arising from hyper conjugative interactions, charge delocalization has been analyzed using natural bond orbital (NBO) analysis. In addition, NLO, MEP, Mulliken, thermodynamic properties, HOMO and LUMO energy gap were theoretically predicted. The global chemical reactivity descriptors are calculated for MFMSF and used to predict their relative stability and reactivity. The antibacterial activity of the compound was also tested against various pathogens. The molecular docking studies concede that title compound may exhibit PBP-2X inhibitor activity. © 2015 Elsevier B.V. Source

In this paper, an implantable CPW-fed double-crossed-type triangular slot antenna mounted over human tissue is proposed for biomedical applications. The proposed antenna covers the ISM band of 2.45 GHz. The radiation parameters such as return loss, VSWR, Z-parameter are analyzed using the method of moments software (IE3D).The proposed antenna has substantial merits like miniaturization, lower return loss, and better impedance matching and high gain over other implanted antennas. © Springer India 2014.

A bio-based green solvent, lactic acid, is found to be an efficient reaction medium for the catalyst free oxidation of arylboronic acids into phenols with aqueous hydrogen peroxide. Various substituted arylboronic acids have undergone ipso-hydroxylation smoothly at room temperature to provide corresponding phenols in excellent yields. Remarkably, the oxidation susceptible functional groups such as sulphide, ketone, aldehyde and olefin are tolerated under the reaction conditions. Over all, lactic acid showed higher efficiency as a solvent medium when compared with conventional acetic acid. © The Royal Society of Chemistry 2015. Source
