Spatial distribution of temperature and temperature instability of a thermoelement
Journal of Engineering Physics and Thermophysics, 1998We show that, depending on the spatial distribution of temperature in semiconducting thermoelements, both "negative" (onset of temperature instability at negative temperature differences) and "positive" temperature instabilities may set in.

Study of the Winding Temperature Distribution for Distribution Transformers
Applied Mechanics and Materials, 2014In this article, in order to provide a reference for determining the location of fiber optic temperature probe in saving distribution transformers,we analyze the internal transformer by the basic heat transfer theory and simulate via ANSYS simulation software, determining the location of the highest temperature separately of the high and low voltage ...

Temperature control of a distributed collector field
Solar Energy, 1995Abstract In this paper an investigation of a temperature control with mass flow manipulation for a distributed field of parabolic trough collectors is described. The dynamics of a collector loop are modelled by a set of nonlinear first-order hyperbolic partial differential equations. A computer model is set up to calculate the closed-loop response of

A polynomial network for predicting temperature distributions
IEEE Transactions on Neural Networks, 1994Complete temperature distributions are unavailable for many locations throughout the world. This distributional information is important for product design and operational planning. The problem of obtaining these temperature distributions is quite difficult and current techniques are limited in accuracy.

Simultaneous distributed strain and temperature measurement
Applied Optics, 1999Brillouin-scattering-based sensors are capable of measuring either the strain or the temperature along the length of an optical fiber in a distributed fashion through measurement of the Brillouin-frequency shift. The cross sensitivity of the frequency shift to these two parameters makes it impossible to differentiate between them by measurement of the ...

Temperature distribution in the dielectric insulation of distribution cables
Annual Conference on Electrical Insulation and Dielectric Phenomena, 2002A theoretical model is developed to accurately determine the rise in the temperature of the core, the dielectric insulation, and the soil surrounding a single-phase distribution cable. The model is capable of predicting the temperature distribution as a function of electric current and cable properties. The model is validated experimentally for an XLPE

Analysis of Spatial Temperature Distribution in ICs
2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007Technology scaling to achieve higher performance and increased functionalities on silicon substrate leads to non uniform temperature distribution across the IC, which will directly impact its performance and reliability. This paper analyzes and discusses the impacts of spatial temperature distribution. A relation between the size of the heat source and

Distributed Temperature Sensors
IEEE Transactions on Industry Applications, 1983The capabilities and technologies of a number of spatially distributed over-temperature sensors are reviewed. A new conductive polymeric sensor is described in which capacitance measurements indicate the presence and location of hot spots. Physical characteristics, operating principles, and test results are discussed.

Temperature Distribution in the Body
2018Heat generated in metabolically active organs is transported to the skin where it is removed from the body. In a warm environment, temperature variation is not large, ranging from 37 to 38 °C in metabolically active organs, such as the braien, heart, and liver, to 30–32 °C on the skin of hands and feet.

Distribution of skin temperature in Mexican children
Skin Research and Technology, 2011Background:Infrared thermography can be a valuable diagnostic tool in the evaluation and management of several pathologies; however, the temperature pattern of the healthy body should be known in order to perform a more precise clinical evaluation.Methods:A total of 25 healthy children (10 female and 15 male) were examined with a thermographic camera ...
