Thermal modeling of thermally isolated microplates

SPIE Proceedings, 2008
In this paper we present an efficient method to calculate the thermal conductance in a thermally isolated microplate, connected to the substrate by two thin arms. The method can be applied to uncooled microbolometer pixels which in general, incorporate a thermally isolated microplate. The model approximates the microplate as a two-region slab, where

A Model of Thermal Acclimation in Cattle

Journal of Animal Science, 1985
A model of temperature effects on cattle daily feed intake has been developed that takes into account (1) time course of thermal acclimation and (2) behavioral responses to short-term thermal stress (STTS). The key difference between this model and the classical intake-temperature model is its consideration of the acclimation state of the animal.

Modeling and Control of Thermal Printing

IEEE Transactions on Control Systems Technology, 2010
In this paper, we present the development of an optimal controller for thermal printheads. A first-order linear system and a nonlinear output mapping with stochastic noise is proposed as a model of the printing dynamics. The model parameters are identified and an optimal control problem is formulated to determine the printhead input.

Modeling of Thermally Assisted Magnetodynamics

SIAM Journal on Numerical Analysis, 2009
Thermomagnetic recording uses local heating of ferromagnetic media to locally decrease coercivity and change saturation magnetization of the material and alleviate magnetization reversal. A modified Landau-Lifshitz equation is proposed as a phenomenological model to allow for changes in magnetization magnitude and is studied both analytically and ...

Model for Thermal Transport in Tokamaks

Physical Review Letters, 1986
The cause for anomalous electron-energy confinement in tokamaks in an active area of research. In this Letter we present a model for the anomalous electron-energy transport and compare it with experimental results.

Thermal Modelling of an Induction Motor

IEEE Transactions on Power Apparatus and Systems, 1983
The comparison of motor losses is a significant item in the study of inverter control strategies for variable frequency, variable speed ac drives. For our study, since it is necessary to differentiate small changes in loss, we have decided to use steady state temperature rise as a direct indicator of loss rather than measurement as the small difference

Thermal Modeling of GaN HEMTs

2010
Thermal effects were investigated to get a better understanding on the role of self-heating effects on the electrical characteristics of AlGaN/GaN HEMTs This is implemented by solving simultaneously the acoustic and optical phonon energy balance equations and also takes into account the coupling of the two subsystems The electro-thermal device ...

A model for thermal monitoring in cryosurgery

American Journal of Obstetrics and Gynecology, 1980
A biological model was designed to test the feasibility of making cryosurgical measurements and to determine if the measurements coincided with a theoretical mathematical model. The object of these studies was to convert cryosurgery from a qualitative to a quantitative therapeutic modality.

Thermal Modeling of a Vibrational Mill

Industrial & Engineering Chemistry Research, 2003
A cogrinding process represents a possible strategy to improve the bioavailability of poorly water-soluble drugs because it allows the formation of composite materials (carrier plus drug) where the drug appears in the form of nanocrystals or in an amorphous phase which competes higher water solubility.
