MATHEMATICAL MODELING Numerical methods play an important role in modern science. Scientific exploration is often conducted on computers rather than laboratory equipment. While it is rarely meant to completely replace work in the scientific laboratory, computer simulation often complements this work.
The physical model results were simulated and incorporated into the mathematical treatment and an improved design for vessel geometry is proposed. The effect of rounding the downleg entrance or installing a baffle between the legs is discussed.
Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. ... ^ Note that when performing a numerical approximation of any mathematical model, convergence of the parameters of interest must be ascertained. Multiple DOF problem converted to a single DOF problem
This feature makes this technique very useful in the modeling of processes which mathematical modeling is difficult or impossible. This work describes some real examples of applications of neural networks in the modeling of some plate mill processes at Companhia Siderúrgica Paulista COSIPA, a Brazilian steelmaker

A mathematical model, which is a mathematical description of a real system, can potentially help to explain a system, to uncover the underlying mechanisms via hypotheses and data fitting, to examine the effects of different components, and to make predictions.
This report describes the principle of producing ultrafinegrained steel, a mathematical model for microstructure evolution, development of facilities, embodiment of an actual mill and the properties of the ultrafinegrained steel rolled in Nakashima Steel Works.
The Crookes radiometer (also known as a light mill) consists of an airtight glass bulb containing a partial vacuum, with a set of vanes which are mounted on a spindle inside. The vanes rotate when exposed to light, with faster rotation for more intense light, providing a quantitative measurement of electromagnetic radiation intensity.
vorable mathematical model of roll force calculation, which is one of the most important terms for process control. For this purpose it is necessary to predict the hot deformation resistance with good accuracy, since it is the predominant factor of the roll force model.
Multidomain model of a steel rolling mill stand with elements for the roll plate, hydraulic system, and electrical motors. Also includes a saved sisotool session with a multiloop controller design to control plate thickness and velocity.
comprehensive mathematical models have been developed for dispersion of fillers in molten plastics (composites) using high shear devices such as extruders. Starting with the coatings area, Wahl et derived a oneparameter model for how the number of "largesize" agglomerates develop over time in a high speed disperser.

Mathematical model for calculating mechanical properties of rolling pipe has been developed. Analysis of the chemical elements was performed influence and technological processing to mechanical properties of pipe steel strength X65X80 class in the thickness range mm.
Dynamic modelling of electronic power steering (EPS) systems is an essential part of vehicle dynamics simulation during the development process in automotive industry. Most of existing models focus on mechanical or drivingcomfort issues ( steering ripple analysis) but do not consider precise modelling of the power consumption of the system.

Abstract: A mathematical model considering the interphase mass transfer both in the downcomer and the riser of an externalloop airlift reactor was established in this paper.
A prerequisite for automatic process set‐up and control in a hot strip mill, in a cold rolling mill, and in a plate mill is to acquire a precision mathematical model for the prediction of the strip profile and the residual stresses. In this paper, an issue is raised regarding the importance of taking into account the effect of post‐deformation.
The modeling in this thesis is made from a control engineer's point of view. Normally, control engineers work with relatively simple dynamical models for the processes. The relatively simple models make it possible to use some more or less advanced mathematics for analysis and design. The
