Justification is a simple technique which was presented for improving the quality of schedules generated with algorithms for solving RCPSPs. Few researches implemented justification with meta-heuristics and proved that algorithms optimization results using justification outperforms the performance of the same algorithms without justification. In this paper, Stacking Justification is presented f...
ABSTRACT In this paper, we introduce a method for stacking data cubelets extracted from interferometric surveys of galaxies in the redshifted 21-cm H},i line. Unlike traditional spectral technique, which stacks one-dimensional spectra cubes, examine based on image domain that makes deconvolution possible. To test validity assumption, mock sample 3622 equatorial GAMA survey, recently imaged as p...
abstract: in this paper, a method for determination of refractive index in membrane of fuel cell on basis of three-longitudinal-mode laser heterodyne interferometer is presented. the optical path difference between the target and reference paths is fixed and phase shift is then calculated in terms of refractive index shift. the measurement accuracy of this system is limited by nonlinearity erro...
Peer to peer lending is famous for easy and fast loans from complicated traditional institutions. Therefore, big data machine learning are needed credit risk analysis, especially potential defaulters. However, imbalance high computation have a terrible effect on prediction performance. This paper proposes stacking ensemble with features selection based embedded techniques (gradient boosted tree...
Stacking procedures with the objective of improvement of signal to noise ratio were in use before the introduction of Common reflection point stacking introduced by Mayne in 1962. But, these techniques were problematic, at times, because they used reflections from a portion of reflectors that were too large. Hence, stacking tends to obscure the very detail of reflector which is being sought. So...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
In the world of knowledge, the amount of data is rising day by day. To explore this huge data various data mining techniques are available, but the result of these techniques is not easily understandable. To simplify the result, different type of visualization technique are available i.e. pixel-oriented, parallel coordinate, stick figure , scatterplot matrics, dimensional stacking and star glyp...
Stability of the ;-; stacking interactions in the substituted-coronene||cyclooctatetraene complexes wasstudied using the computational quantum chemistry methods (where || denotes ;–; stackinginteraction, and substituted-coronene is coronene which substituted with four similar X groups; X =OH, SH, H, F, CN, and NO). There are meaningful correlations between changes of geometricalparameters and t...
As we enter the nanoscale regime, power reduction is of increasing importance, but the established leakage reduction techniques will become less effective. Subthreshold leakage is being joined by band-to-band tunneling and gate leakage as the primary leakage mechanisms. The increased significance of these leakage components threatens the usefulness of some traditional leakage reduction techniqu...
Large-volume sample stacking using the electroosmotic flow (EOF) pump technique has been investigated for the quantification of 3-nitrotyrosine in urine of diabetic rats. The best separation conditions for these highly complex samples were obtained using capillary electrophoresis (CE) in the reversed polarity mode (i.e., injecting at the cathode and detecting at the anode) using cetyltrimethyla...
