In this paper we present a novel heuristic for selection of hyperblock in If-conversion. The if-conversion has been applied to be promising method for exploitation of ILP in the presence of control flow. The if-conversion in the prediction is responsible for control dependency between the branches and remaining instructions creating data dependency between the predicate definition and predicated structures of the program. As a result, the transformation of control flow becomes optimized traditional data flow and branch scheduling becomes reordering of serial instructions. The degree of ILP can be increased by overlapping multiple program path executions. The main idea behind this concept is to use a step beyond the prediction of common branch and permitting the architecture to have the information about the CFG (Control Flow Graph) components of the program to have better branch decision for ILP. The navigation bandwidth of prediction mechanism depends upon the degree of ILP. It can be increased by increasing control flow prediction in procedural languages at compile time. By this the size of initiation is increased that allows the overlapped execution of multiple independent flow of control. The multiple branch instruction can also be allowed as intermediate steps in order to increase the size of dynamic window to achieve a high degree of ILP exploitation. © 2011 IEEE.

Mobile Ad-hoc Network (MANET) has emerged as the self organized wire less interconnection for the various applications in random topology. As most of the multimedia applications require strict QoS guarantee during the communication between a single source and multiple destinations. How ever, achieving reliable multicast transmission in MANET is crucial due to the dynamic network topology caused by the node mobility. This gives rise to the need for an efficient multicast routing strategy. This paper proposes a novel scheme PBMRP-BR (position-based Multicast Routing Protocol for Ad-hoc Network Using Backpressure Restoration) for efficient transmission of multimedia applications in Ad-hoc Network, which provides priorities for routing based on Distance of path, Load at the node (ie, traffic) and queue length at the node (ie, bandwidth). It also keeps the path information including bandwidth resources of each node for routing decisions. The problem of the link failure in the channel during the call in progress thus lead in the degradation of the QoS (Quality of Service). To deal this we are using a Backpressure Technique The simulation results shows that the proposed algorithm is able to find a better solution, fast convergence speed and high reliability. The simulation results shows the proposed PBMRP-BR protocol achieve the above objectives and gives the batter results than previous schemes like DSR for the maintenance of overheads and the path reliability. Our proposed scheme will improve the bandwidth utilization by reducing the congestion in the Adhoc wireless network. © 2010 IEEE.

This study is an attempt to explore the possibility of solidification/ stabilization (S/S) of hospital solid waste incinerator ash(HSWIA) with an aim to eliminate/reduce the presence of toxic elements with in acceptable limits so that the same may be utilized in the geotechnical construction. To achieve the objectives, hospital solid waste incinerator ash (HSWIA) was mixed with alluvial soil in different proportions and optimum percentage of HSWIA was obtained based on the strength criteria. Leachate tests were conducted on the samples prepared at optimum HSWIA-soil percentage in order to determine the percentage of toxic elements present. Solidification/stabilization was carried out using cement (OPC) as binder. The degree of effectiveness of S/S product was established by strength and leaching tests. The experimental result shows the marked decrease in the toxicity with an increase in the strength of S/S product. © 2012 American Society of Civil Engineers.


The emerging structures in spinodal dewetting of thin nano films and spinodal decomposition of binary mixtures are found to be similar with certain differences attributed to the nonlinearities inherent in the wetting forces. This paper deals with the technological aspects of the spinodal processes by giving a brief account of the theory and to correlate the two phenomena termed as spinodal dewetting of thin nanofilms and surface-directed phase separation. The MC simulation micrographs at early stage of spinodal dewetting of a (linear) polymer film confined between two hard walls (using FENE potential between the beads on same chain and Morse potential between inter and intra chain beads) show similarities with surface-directed phase separation (using metropolis algorithm) in creation of holes. The spinodal dewetting is also criticized on the basis of global minimization of free energy emerging from dipole-quadrupole interactions. A novel molecular scale-driving mechanism coming from asymmetric interface formation in spinodal processes is also proposed. It can be believed that the modeling done with the films under confinement of two walls works as a classical mathematical ansatz to the dipole-quadrupole interaction coming from quantum origins and giving rise to lateral interactions in the process reflecting a colossal behavior in thin nano films though weak in nature.

In this paper, the analytical study of the modal characteristics, cutoff condition and dispersion curves of circular optical waveguide having various cladding layers are presented. The proposed three structures of waveguide have three parts namely core with highest refractive index dielectric material, inner claddings and outer cladding. The guided modes and propagation wave vectors can be evaluated by using a determinant which is constructed by the boundary matched method under the weakly guiding condition. The cutoff conditions of modes for varying number of inner claddings are compared. The analysis shows that one can control the propagation property of optical waveguide by increasing the number of inner claddings. These claddings provide additional degree of freedom to control the modes. © 2013 Elsevier GmbH. All rights reserved.

The Fast Fourier Transform (FFT) method is successfully used for the broken rotor bar fault detection purpose in the induction machines. It is based on the common-steady state analysis of the motor. This method is successfully used with Motor Current Signature Analysis (MCSA) technique for last three decades. However, this method is suffered from some serious drawbacks such as; it is applicable only in the constant load condition not for the variable load. The frequency-domain methods which are commonly used need accurate slip estimation for frequency components localization in any spectrum. It is also not suitable at the no-load or light load condition of the motor. At light load condition, it is quite difficult to distinguish between healthy and faulty rotors because the characteristic of broken rotor bar fault frequencies are very close to fundamental component and their amplitude are small in comparison. As a result, detection of the fault and classification of the fault severity under light load is almost impossible. In order to overcome the above problems of the FFT based technique, the Short Time Fourier Transform (STFT) Method was proposed. The excellent feature of this method is that it is capable to diagnose broken rotor bar fault in the transient condition. The STFT method also suffered from the drawback that it shows the constant window for all the frequencies. Therefore, it shows poor frequency resolution. In order to overcome all the problems stated so far, the most recent powerful mathematical tool i.e. Wavelet Transform (WT) has been used in the rotor broken bar fault detection purpose at all loading conditions. It shows variable window size for all the frequencies. Therefore, the WT method does not have resolution problem due to its multiresolution feature. This paper investigates the detection of rotor faults in induction machines by analyzing the starting current using a newly developed quantification technique based on the wavelet transform. The technique applies the wavelet transform to the envelope of the starting current. The envelope extraction is used to remove the strong fundamental component, which overshadows the characteristic differences between a healthy motor and a faulty motor with broken rotor bars. © 2012 IEEE.

Now-a-days SiGe HBTs are surpassing even the fastest III-V production devices in the high-speed orbit. The state-of-art in simulation of silicon germanium semiconductor devices is presented in this paper. A comprehensive course of action to model the device parameter characterization of High Frequency 0.1μm SiGe HBT is depicted which is based on the technique of direct parameter extraction. With the help of S-, Y- and Z- parameters, the equivalent circuit parameters have been extracted in a faultless approach. The intrinsic and the extrinsic elements of model are obtained using a direct extraction method that assists to find out the base resistance from the Z- parameters. In this, the issues entailed in simultaneous optimization of fmax and fT and related optimization of base resistance as well as junction capacitance are addressed. The device characteristics of the SiGe HBT are found much advance to those of III-V semiconductor devices. A corroboration of objective validity of the modeling scheme and the extraction of parameter is accomplished in the form of S-parameters. These results have been validated using a viable numerical device simulator ATLAS from Silvaco International.

Surface roughness plays an important role in product quality particularly in situations such as precision fits and high strength applications. Magnetic abrasive finishing (MAF) is relatively a new finishing process among the advanced finishing processes, which produces a high level of surface quality and is primarily controlled by magnetic field. In MAF, workpiece is kept between the two poles of a magnet. The working gap between the workpiece and the magnet is filled with magnetic abrasive particles. Asa result, magnetic abrasive flexible brush (MAFB) is formed, acting as a multipoint cutting tool, due to the effect of magnetic field in the working gap. This paper deals with the theoretical investigations of MAF process. A finite element model of the process is developed to evaluate the distribution of magnetic forces on the workpiece surface. MAF process removes very small amount of material by indentation and rotation of magnetic abrasive particles in the circular tracks. In this investigation, a three factor two-level full factorial design is employed to perform a series of numerical experiments. The working gap, flux density and size of magnetic abrasive particles are taken as process variables. The results are employed to reveal the main effects as well as interaction effects of these three factors on surface quality.

Gravitational waves are an inevitable consequence of Einstein's theory of gravitation, which are meaningfully comparable with electromagnetic waves except for their non-conformal invariance. So, Einstein's field equations aremodified by a straightforward generalization of the Lagrangian in the Einstein-Hilbert action by choosing a polynomial in the scalar R of a finite number of terms. In this modified theory of gravity, conformally invariant gravitational waves are obtained. Besides this, cosmological aspects and the gravitational field surrounding a spherically symmetric mass distribution are studied to understand the features of this theory. It reveals that the deviations are not so significant at the observational level, and the features are more or less similar to those of Einstein's theory. © 2014 Pleiades Publishing, Ltd.

Assessment of Seismic Hazard (liquefaction potential) of soil deposit during an earthquake is normally evaluated based on method proposed by Seed (1979). However, it is assumed in this method that the energy transfer to SPT rod is 60% of the theoretical potential energy. SPT hammer used in India is different than that is used in USA. Thus, the efficiency of SPT hammer used in India is different and we can not take its SPT "N-value" equivalent to N60. There is need to use certain correction factor to convert it to N60 but no standard correction factor is available for India. Present use of SPT N-value equivalent to N60, leads to inaccurate prediction of seismic hazard which is highlighted in this paper. © 2010 CAFET-INNOVA TECHNICAL SOCIETY. All rights reserved.
