The use of magnetron sputtering for deposition the metal electrode in perovskite solar cells has been limited because damage to organic hole transport layer by high kinetic energy particles during process. In this paper, a systematic investigation into effect power, argon flow rate, duration, and pressure on performance was conducted. results work show that power conversion efficiency 18.35% ob...

Because of Polarimetric Synthetic Aperture Radar (PolSAR) contains the different features which relate to the physical properties of the terrain in unique ways, polarimetric imagery provides an efficient tool for the classification of the complex geographical areas. Support Vector Machines (SVMs) are particularly attractive in the remote sensing field due to their ability to handle the nonlinea...

This paper presents the optimum combination of major parameters for high mechanical efficiency of a compact scroll compressor with a fixed cylinder diameter. The mechanical efficiency was calculated for a number of cylinder volumes, where the cylinder diameter and the scroll thickness were fixed at a constant value of 75.7 mm and 4 mm, respectively, and combinations of the involute base circle ...

the taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow g by electrocoagulation (ec) using iron and steel electrodes as anode and cathode, respectively. an orthogonal array (oa9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...

In this paper we give the optimum parameters for the Accelerated Overrelaxation (AOR) method in the special case where the matrix coefficient of the linear system, which is solved, is consistently ordered with nonvanishing diagonal elements. Under certain assumptions, concerning the eigenvalues of the corresponding Jacobi matrix, it is shown that the optimum AOR method gives better convergence ...

Using the experimental design methods, instead of deterministic ones commonly used by chemists, to estimate the kinetic constants is a very important subject in chemical researches, since such-obtained kinetic parameters have much better statistical properties. D-optimum design is a popular statistical technique, which emphasizes to obtain the estimated parameters with the smallest content of t...

An approach to compute optimum seismic design parameters is presented. It is based on the optimization of the expected present value of the total cost, which includes the initial cost of structures as well as the cost due to earthquakes. Different types of seismicity models are considered, including one for characteristic earthquakes. Uncertainties are included in some variables to observe the ...
