Airflow over the wavy yarn during air-jet filling insertion is analyzed theoretically Two flow regimes are considered in the analyses: subsonic and supersonic flows over the yarn. Expression for drag coefficient as a function of air velocity is obtai...
This paper concerns the development of the mat mathematical model of sulphomethylation process of nonylphenol based on planning of the experiment While developing the mathematical model of the process. a method of gross factor experiment (GFE). reali...
A procedure for definition of neighborhood and fault free subcubes in a faulty hypercube is developed in this study. The cube algebra operations are used for proposed procedure. With this, we can increase the number of faulty elements In the hypercub...
It is widely assumed that the magnetic phase transition temperatures have constant values. Application of the formalism of the high accuracy spectroscopic method shows that the Curie points used for the calibration processes in magnetic measurements...
The finite element was used to temperature changes with time to Au-AgPd alloy and porcelain crowns in three dimensional models of average maxillary second premolar. Temperature changes some critical nodes were calculated as a result of hot/cold liqui...
In this article finite differences are used to study viscoelastic incompressible flow of a Criminale Erickson Filbey fluid in a square cavity flow domain. In this case, the nature of corner singularities is examined in which the fluid is contained an...
Mining investments require huge capitals. Since mining has an economical aspect, a reasonable profit is expected at the end of investment. In other words, a mining investment is reasonable only if it brings a desirable income. In fact. The objective...
In this study, new approaches are proposed over a range of conditions with unknown loading time to determine the initial conditions and identify the explicit model parameters of successive weighing system in the early part of the transient response....
In this study the kinetics of reactions of Nin n=7 and 9, clusters with a deuterium D2 molecule are studied via quasiclassical molecular dynamics. Dissociative chemisorption probabilities as functions of impact parameters, collision energies, and a r...
In the present work, we have obtained principally new results for solvability and non-solvability of one problem for second order abstract differential equations with the main linear part. The method, based on solving corresponding Dirichlet problem,...
