Aerodynamic Analysis of Aircraft Wing
Tập 31 Số 2 - 2015
Aerodynamic problems in general are often difficult to solve by analytics
analysis. Experimental or numerical simulation can be used to analyze these
computational models. However, due to the large expenses required in the
experimental method, the numerical method is more preferred. This paper presents
the modeling and simulating processes of computational fluid dynamic (CFD)
problem on a aircraft...

Satellite Tracking Control System Using Fuzzy PID Controller
Tập 31 Số 1 - 2015
This paper presents the results of study, design and manufacture of a searching
and satellite auto-tracking system used for mobile receiver. This system applies
both the traditional proportional integral derivative (PID) control and the
fuzzy PID control methods. Firstly, the PID controller was designed by
Ziegler-Nichols tuning method to obtain control parameters. Then, a fuzzy
controller was app...
Calculation of Morse Potential Parameters of bcc Crystals and Application to Anharmonic Interatomic Effective Potential, Local Force Constant
Tập 31 Số 3 - 2015
In this work, Morse potential parameters of bcc crystals have been calculated
based on the calculation of volume per atom and atomic number in each elementary
cell, as well as the energy of sublimation, the compressibility and the lattice
constant. They are used for studying the anharmonic interatomic effective
potential, local force constant in XAFS (X-ray Absorption Fine Structure)
theory. Numer...

Preparation of NiFe2O4 - TiO2 nanoparticles and study of their photocatalytic activity
Tập 27 Số 4 - 2011
Abstract. In this article, the authors describe the method for preparation of
NiFe2O4 – TiO2 magnetic nanoparticles and present the results on study of their
photocatalytic activity. NiFe2O4 nanoparticles have been prepared by
coprecipitation using spraying technique with subsequent hydrothermal
processing. NiFe2O4-TiO2 composite nanoparticles were prepared by covering thin
films of TiO2 on the su...
Mg-doped TiO2 for dye-sensitive solar cell: An electronic structure study
Tập 28 Số 2 - 2012
Abstract. Recently, there has been a renewed interest in TiO2 anatase as charge
transfer layer in dye-sensitized solar cells (DSSC). In this work, the
electronic structure of Mg-doped TiO2 anatase was explored in the framework of
density functional theory (DFT). The results showed that the substitution of
Mg2+ ions for Ti4+ ions was quite easy in comparison with non metalic doping
case. It induced...
Preparation of Au-Ag Alloy Nanoparticles for Surface Enhanced Raman Scattering
Tập 31 Số 1 - 2015
Using a laser-based method we study the preparation of Au-Ag alloy nanoparticles
for Surface enhanced Raman scattering (SERS). Au and Ag nanoparticles (NPs) were
prepared in distilled water by pulse laser ablation using 1064nm wavelength of
Nd:YAG laser. Au-Ag alloy NPs were prepared by irradiating the mixture of
colloidal Au and Ag NPs with the 532 nm second harmonic wavelength of Nd:YAG
laser. T...
