For System on-chip (SoC) designs in current Deep Submicron (DSM) era, interconnects play important role in overall performance of the chip. The factors such as propagation delay, power dissipation and crosstalk through RC modeled interconnects substantially affects the entire working of the chip. Functional crosstalk and crosstalk induced propagation delay have recently emerged as major sources of faults. The crosstalk effect is a consequence of coupling and switching activities that is encountered when there is a transition in previous state of wire as well as when transitions are in adjacent wires. Therefore, minimization or elimination of switching and coupling activities is crucial in enhancing the performance of SoC designs. This paper proposes encoding schemes in order to achieve reduction in transitions between the previous and present states of wire as well as transitions in adjacent wires. The reduction in transition improves the performance in terms of power dissipation, coupling activity and delay in on-chip bus. © 2010 IEEE. Source

Fluoride (F) contamination is a global environmental problem, as there is no cure of fluorosis available yet. Prosopis juliflora is a leguminous perennial, phreatophyte tree, widely distributed in arid and semi-arid regions of world. It extensively grows in F endemic areas of Rajasthan (India) and has been known as a "green" solution to decontaminate cadmium, chromium and copper contaminated soils. This study aims to check the tolerance potential of P. juliflora to accumulate fluoride. For this work, P. juliflora seedlings were grown for 75d on soilrite under five different concentrations of F viz., control, 25, 50, 75 and 100mgNaFkg-1. Organ-wise accumulation of F, bioaccumulation factor (BF), translocation factor (TF), growth ratio (GR) and F tolerance index (TI) were examined. Plant accumulated high amounts of F in roots. The organ-wise distribution showed an accumulation 4.41mgkg-1dw, 12.97mgkg-1dw and 16.75mgkg-1dw F, in stem, leaves and roots respectively. The results indicated significant translocation of F from root into aerial parts. The bioaccumulation and translocation factor values (>1.0) showed high accumulation efficiency and tolerance of P. juliflora to F. It is concluded that P. juliflora is a suitable candidate for phytoremediation purpose and can be explored further for the decontamination of F polluted soils. © 2012 Elsevier Ltd. Source

Purpose - The purpose of this paper is to focus on studying the concept of "Smart Organization" and providing a comprehensive framework for the various factors as barriers for the smart organization, identifying and classifying the key criterion of these factors based on their direct and indirect relationships. Design/methodology/approach - In this paper an extensive literature survey and experts' opinion have been used to identify major barriers of smart organization. These barriers are then modeled using interpretative structural modeling (ISM) methodology. The model so developed has been further improved and an integrated model has been developed using fuzzy-MICMAC. Findings - Various barriers of smart organization have been identified and a structural model has been developed for barriers using the ISM methodology.The critical barriers have been found out by fuzzy-MICMAC analysis. The driver power and dependence graph has been plotted for barriers. The barriers are classified into four categories which are, autonomous, linkage, dependent and independent according to their driver power and dependence. From the ISM model and the integrated model, and from further discussions with the experts, it has been found that the barriers "(B1) organizational structure" and "(B6) Managerial actions" are the two most important barriers, every other barrier is directly or indirectly driven by these. Research limitations/implications - The basis of developing the ISM model, i.e, the structural self-interaction matrix is based on experts' opinion, therefore the result may get influenced if there is any biasing in judging the barriers. The future research scope for this paper will be to test the model generated in this paper. The testing of the model can be done by applying structural equation modeling technique, it has the capability of testing the hypothetical model. Further a framework of smart organizations can be created to find out the smartness of different organizations. Practical implications - The paper can be used by organizations in understanding the barriers in becoming "smart" on the basis of their inter-relationships. This model can help manufacturing organization of North India in understanding the barriers which needs to be worked upon and the inter-relationship among these factors. This model-based study may be helpful in understanding and implementing the practices of smart organization by removing the possible critical barriers. Originality/value - This is the first study to identify the barriers of smart organizations and to develop a model of these barriers using ISM and fuzzy-MICMAC. © Emerald Group Publishing Limited.

A novel dual-band asymmetric slit with defected ground structure microstrip antenna for circular polarization (CP) operation is proposed. In which, the lower resonant band is excited by cutting asymmetric slit on square microstrip antenna, and a new concept of defected ground with truncated corners structure is used to excite upper resonant band. The antenna is practically fabricated and simulated. Measured results show a good agreement with simulated results. Antenna is compact in size and shows a good quality of polarization at both resonant bands. Antenna shows the bandwidth of 7.5% (2.30-2.48 GHz) and 2.94% (3.80-3.9 GHz) at lower and upper bands, respectively. The antenna also shows 40 and 11 MHz, 3-dB axial ratio bandwidth at lower and upper bands, respectively. The return loss and radiation pattern of the proposed antenna remain consistent for both resonant bands. Copyright © 2013 Wiley Periodicals, Inc. Source

In the present paper, the isothermal Suzuki's EOS which is used to study the compression behaviour of solids has been shown to be mathematically inconsistent. It is mentioned that it should be modified to satisfy the basis thermodynamic conditions. The mathematically consistent modified Suzuki's EOS is applied to study the compression behaviour of different class of solids (MoN, MoN2, Os, γ-SnS, SiC, FeS2, α-SnS and Ge). The results obtained using the thermodynamically consistent formulation i.e. modified Suzuki's EOS are found to be in better agreement with the experimental data than the mathematically inconsistent Suzuki's EOS. Pressure dependence of bulk modulus for these solids using the present formulation is also given and discussed. © 2015 Old City Publishing, Inc. Source
