An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...

Image separation is defined as decomposing a real world image mixture into individual images objects. Independent component analysis is an active area of research and is being utilized for its capability in statistically independent separation images. Neural network algorithm ICA has been used to extract interference and mixed images and a very rapid developed statistical method during last few...

Abstract: point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abadarea in Kerman, Iran. Experiments were designed by using LThe influence of each variable and their interactions on the operation of the device was studied. The variables underinvestigation were: table slope, table frequency, water flowrate, feed rate, and particle size. ...

this field study was conducted on 60 women who working in related centers of universities of medical sciences in tehran. data gathering tool was maternal separation anxiety questionnaire that designated by hock & et al. (1982).  findings revealed that majority of the research units (71.7%), have high degree of maternal separation anxiety. mean degree of maternal separation anxiety was (21.22±3....

in this work, we developed a simple and selective method for separation and spectrophotometric determination of trace amounts of cetylpyridinium chloride (cpc) in pharmaceutical products using cloud point extraction (cpe) technique. the method is based on cloud point extraction of the cpc in alkali conditions using of nonionic surfactant triton x-114. under selected conditions, the calibration ...

In this paper, we propose compositional separation logic with tree predicates (CSLTP), where properties such as sortedness and heightbalancedness of complex data structures (for instance, AVL trees and red-black trees) can be fully specified. We show that the satisfiability problem of CSLTP is decidable. The main technical ingredient of the decision procedure is to compute the least fixed point...

â a model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. while the model’s solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the cpu time is decreased ess...

This paper presents new blind separation methods for Moving Average (MA) convolutive mixtures of independent MA processes. They consist of time-domain extensions of the FastICA algorithms developed by Hyvärinen and Oja for instantaneous mixtures. They perform a convolutive sphering in order to use parameter-free fast fixed-point algorithms associated with kurtotic or negentropic nongaussianity ...

Independent Component Analysis (ICA) separates spatial and temporal components of fMRI data which may consist of activation patterns, cardiac and respiratory tasks and other artifacts. In this study sources of (fMRI) data are separated using ICA based on simple fixed point iteration method and steepest ascent method. Both are the simplest methods used in optimization. However in this study comp...

A set of experiments are designed to evaluate and compare the performances of three well known blind source separation algorithms in this paper. The specific algorithms studied are two group of neural networks algorithms, Bell and Sejnowski’s infomax algorithm and Hyvärinen’s fixed-point family, and J. F. Cardoso’s joint approxomate diagonalization of eigen-matrices algorithm. In this paper, th...
