This study presents a method for fingerprint recognition based on principal component analysis (PCA) and point patterns (minutae) obtained from the directional histograms of a fingerprint. We first employ Principal Component Analysis (PCA) method to...
Collisionless fragmentation of a non-rotating Ni19 cluster is studied using constant-energy molecular dynamics computer simulations. The cluster is modelled by an embedded atom model (EAM) energy surface. Distribution of the channel-specific fragment...
β-decay provides important information about the structure of halo nuclei. Because of the root-mean-square radius (Rrms) of the neutron halo distribution is very large, the phase-space factor for halo nuclei must be more sensitively depended on the r...
The problem of peristaltic transport of a non-Newtonian fluid represented by the constituve equation for a third grad fluid was analysed for the case of planar channel with harmonically undulating extensible wall, under zero Reynolds number and long...
An overview of major signal processing and analysis methods finding an area of application in machinery fault diagnostics is presented. Among them Wavelet Transform, which has been gaining a special interest in many research and engineering fields, i...
This paper studies the error analysis of determining airplane location by global positioning system (GPS) using statistical testing method. The Newton Rhapson method positions the airplane at the intersection point of four spheres. Absolute errors, r...
In this study, some problems connected with stochastic process with a discrete chance interference X(t) are investigated. In particular, one-dimensional distribution functions of the process are obtained and under some weak assumptions, the ergodic t...
With the advancement of new materials and techniques, smooth and high performance operation of critical systems such as fight simulators, satellite navigators and robots arms are desired in these systems, often more than one objective has to be accom...
A theoretical approach for estimation of the drag correlation coefficients in the flow of Newtonian or weak non-Newtonian liquids around spherical solid particles is presented. Some new analytical relations are derived by using a modified stream func...
A two dimensional, multi-link sagittally symmetric whole-body model was developed to simulate an optimal trajectory for manual material lifting. Non-linear optimal control techniques and genetic algorithms were utilized in the simulations to explore...
Faults in computer control systems cause great economic losses and endanger human beings. In order to ensure control and monitoring tasks, the availability and safety of computer control systems in areas such as military, manufacturing plants, traffi...
