Modelling of Polymer Crystallization in Temperature Fields
ZAMM, 2002Summary: This paper is devoted to the mathematical modelling of polymer crystallization processes in a bounded region under heat transfer conditions, i.e. in time-dependent temperature fields. A stochastic model in a general setup is developed based on the theory of marked point processes, and a hybrid model on a macroscopic scale is derived using ...

The modeling of temperature field in the sensor zone
ITI 2008 - 30th International Conference on Information Technology Interfaces, 2008Temperature fields in the region of the temperature sensors are simulated. Two versions of the sensors placement relative to the heat transfer agent are analyzed. It is established that in the case of sinking the sensor with the bushing into the heat-transfer agent flow the sensor and the part of the surface of the wall of pipe must be covered with ...

The origin of welding residual stresses and welding distortion is the concentrated heat input, both locally and in terms of time, by which a fusion zone is produced at the welding spot (fusion welding). With the combined action of pressure producing local plastic deformations, heating to just below the melting temperature is also sufficient (pressure ...

A study of temperature field in a GaN heterostructure field-effect transistor
Microelectronics Journal, 2003This paper presents a three-dimensional finite element based heat transfer model for a Gallium Nitride-based Heterostructure Field-Effect Transistor (henceforth referred to as GaN HFET). Analyses were carried out to study the distribution of temperature in the HFET under steady-state conditions for two different steady-current inputs.

Temperature dependences in field ionization
International Journal of Mass Spectrometry and Ion Physics, 1973A model of field ionization which describes a general expression for the ionization coefficient is presented. Simplifications of this expression result in approximate formula for the ionization coefficient as a known function of physically evident variables and parameters.

Sleep and the temperature field of the bed
Journal of Thermal Biology, 1993Abstract 1. 1. In order to find a correlation between the thermal conditions in bed and the quality of sleep, 5 young, healthy persons were tested in a thermal climate chamber. 2. 2. The sleep of each person was thoroughly monitored during 5 nights (stages I to IV, REM, awake) with continuous registration of 14 temperatures, 12 distributed in

Particle fields at finite temperature from string field theory
Physical Review D, 1991An investigation is made into the finite-temperature behavior of a class of scalar field theories derived from string field theory. The fields {tilde {phi}} are the lowest-order fields in a level truncation of the open bosonic string and have momentum-dependent couplings. Expressions for the one-loop effective potential for {phi}{sup 3} and {tilde {phi}
