Analysis on improving operational efficiency of construction project site

Operational efficiency directly reflects the profitability of a project. It is for benefit of a construction site. The current research paper focus on high operational efficiency by reducing waste, better layout planning, sound administration, business practices an, review of existing facilities etc. To improve the operational efficiency will enhance the profit by adding the value to the project in the form of cost reduction in internal transportation, utilization of existing facilities effectively. The study adopted the Computerized Relative Allocation of Facilities Techniques (CRAFT) and computerized relationship planning (CORELAP) algorithm to analyze the operational efficiency

Significance of Weighted-Type Fractional Fourier Transform in FIR Filters

The desired frequency response of a filter is periodic in frequency and can be expanded in Fourier series. One possible way of obtaining FIR filter is to truncate the infinite Fourier series. But abrupt truncation of the Fourier series results in oscillation in the pass band and stop band. These oscillations are due to slow convergence of the Fourier series by the Gibb's phenomenon. To reduce these oscillations the Fourier coefficients of the filter are modified by multiplying the infinite impulse response with a finite weighing sequence called a window. The Fourier transform (FT) of a window consists of a central lobe and side lobes. The central lobe contains most of the energy of the window. To get an FIR filter, the desired impulse response and window function are multiplied, which results to give finite length non-causal sequence. Since Fractional Fourier Transform (FrFT) is generalization of FT. Here an attempt is to implement filters using window by using Weighted Type Fractional Fourier Transform (WFrFt), differentiator and integrator using weighted FrFt is also present

A Motion Estimation based Algorithm for Encoding Time Reduction in HEVC

High Efficiency Video Coding (HEVC) is a video compression standard that offers 50% more efficiency at the expense of high encoding time contrasted with the H.264 Advanced Video Coding (AVC) standard. The encoding time must be reduced to satisfy the needs of real-time applications. This paper has proposed the Multi- Level Resolution Vertical Subsampling (MLRVS) algorithm to reduce the encoding time. The vertical subsampling minimizes the number of Sum of Absolute Difference (SAD) computations during the motion estimation process. The complexity reduction algorithm is also used for fast coding the coefficients of the quantised block using a flag decision. Two distinct search patterns are suggested: New Cross Diamond Diamond (NCDD) and New Cross Diamond Hexagonal (NCDH) search patterns, which reduce the time needed to locate the motion vectors. In this paper, the MLRVS algorithm with NCDD and MLRVS algorithm with NCDH search patterns are simulated separately and analyzed. The results show that the encoding time of the encoder is decreased by 55% with MLRVS algorithm using NCDD search pattern and 56% with MLRVS using NCDH search pattern compared to HM16.5 with Test Zone (TZ) search algorithm. These results are achieved with a slight increase in bit rate and negligible deterioration in output video quality

Production of antibodies specific to human chorionic gonadotropin in mice immunized against its chemical analogs

Mice immunized against DS5-hCG-β and DS6-hCG-β, chemical analogs of β-subunit of human choriogonadotropin (hCG-β) in which 5 and 6 disulphide bonds respectively were reduced and alkylated, were found to produce antibodies specific to hCG without significant crossreactivity with human lutropin (hLH) as tested in a radioimmunoassay. In contrast, mice immunized against the native hCG-β subunit produced hLH crossreacting antibodies. While the anti-DS5, DS6-hCG-β serum was capable of selectively blocking the binding of [125I]-hCG to rat testicular LH/hCG receptors, it failed to inhibit the binding of [125I]-hLH to the same receptors. The radioimmunoassay for hCG using the mouse anti-DS5, DS6-hCG-β serum was not as sensitive as that employing rabbit anti-DS5, DS6-hCG-β serum. The minimal detection limit was 5 ng/ml for the mouse antibody as compared to 1 ng/ml for the rabbit antibody

Measurements of Three Dimensional Temperature Field in Fluids using Laser Interferometry

Non-intrusive measurement of fluid temperature using laser interferometry is reported. As a case study, results obtained in Rayleigh-Benard convection experiment are presented. Image processing operations required for the evaluation interferograms and extraction of quantitative data from the optical Images are discussed. Limited-view tomographic algorithms applicable to interferometry are discussed and compared in terms of reconstructed three-dimensional temperature fields. This study concludes that laser interferometry coupled with tomography promises a versatile tool for three-dimensional temperature and flow field measurements in fluids

Image Reconstruction from Incomplete Projection Data using Combined ART- CBP Algorithm

The present work is concerned with reconstructing cross-sections of composite structures when complete projection data is not available from the experiments. A novel approach combining the algebraic reconstruction technique (ART) and convolution back projection (CBP) algorithm has been developed for reconstruction with such data. The numerical results obtained reveal that a combination of ART and CBP is able to reconstruct cross-sections from incomplete data to an extent that is meaningful for non-destructive evaluation

The Influence of GRA and TOPSIS for Assortment of Green Supply Chain Management Strategies in Cement Industry

The present paper aimed at proposing new strategies for evaluating the green supply chain management for enhancing the priority to environmental factors in cement manufacturing life cycle analysis, there by reducing the carbon foot prints. These strategies help in producing eco-friendly products there striking the balance between economy and environment. Initially green supply chain priorities are defined by using grey relational analysis (GRA). The priority weights obtained by GRA method is used to determine the weight for each indicator selected in the present study and then GRA is combined with TOPSIS methodology to obtain the priority for level-II measurement indicators used in the present study. These strategies will influence the decision making priorities during cement manufacturing.
