LOW TEMPERATURE BEHAVIOR OF DEBYE CHARACTERISTIC TEMPERATURES
Canadian Journal of Physics, 1958The low temperature behavior of the characteristic Debye temperature is investigated using the six- and nine-direction Houston approximation and by way of illustration, the lattice dynamics of Born and Begbie (nearest neighbors only). We study the values of θ0 and B2 for Cu, Au, Ag, Al, and Pb in the formula θT = θ0 θ. The existence in Pb of a shallow

Shaping of the characteristics of temperature-sensitive elements
Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1954A method for shaping the characteristics of temperature-sensitive elements is described, together with a practical example. The proposed method permits the shaping of characteristics of the temperature-sensitive elements in order to obtain the desired form.

Temperature Dependence of the Characteristic Travel Distance
Environmental Science & Technology, 2003The effect of temperature variation on the environmental fate of organic chemicals can be evaluated in steady-state multimedia box models by expressing chemical partitioning data and reaction rate coefficients as functions of temperature. Using such a modelthetemperature dependence of the characteristic travel distance in air L(A), which is a measure ...

Characteristics of isolated vortices at arbitrary temperatures
Physica C: Superconductivity, 1994We suggest the method of microscopic calculation of the properties of vortices, valid at arbitrary temperatures, and calculate the energy of the static vortex epsilon(0), its effective mass and dissipation at T = 0. The method consists of expressing the energy of an isolated vortex (moving with the constant velocity v) through the dielectric function ...

Second sound and characteristic temperature in solids
Physical Review B, 1996A temperature pulse propagating in a solid is studied by simple wave theory. The aim is to determine the shape change of the pulse, which initially is given by a Gaussian function, using a generalized nonlinear Cattaneo model proposed, in the framework of extended thermodynamics, by Ruggeri and co-workers.

Effects of Low Temperatures on Transistor Characteristics
IBM Journal of Research and Development, 1957This paper reports the results of a number of tests made on a group of PNP alloy junction transistors whose power rating at the usual operating temperature is 30 milliwatts and whose cut-off frequency is about 3 megacycles. The tests show that as the temperature of the transistor is lowered, both the maximum power dissipation and the cut-off frequency ...

Temperature characteristic of fiber Bragg grating
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011The basic principle of temperature sensor based on fiber Bragg grating (FBG) is analyzed. A fiber Bragg grating temperature sensor is designed and produced. Using fiber Bragg grating as the sensor, fiber Bragg grating analyzer to demodulation the wavelength shift, the relationship between FBG wavelength shift and temperature is measured.

Basis for a Characteristic Temperature in Nuclear Fragmentation
Physical Review Letters, 1988The apparent characteristic temperature observed in the fragmentation of highly excited nuclei is studied by calculations using a simple model consisting of an expanding and emitting source. A characteristic temperature for emission, nearly independent of the initial temperature, is found in the calculations, and the underlying physics is interpreted ...

Temperature Characteristics of Electret Silicon Microphones
Proceedings of Meetings on Acoustics, 2010The electret condenser microphone (ECM) has become an important component for various consumer equipment systems because of its stable sensitivity and frequency characteristics and its success in achieving small size and high sensitivity. A previous report described the method to design a microphone with stable temperature characteristics.

Temperature Aging Characteristics of Class A Insulation
Transactions of the American Institute of Electrical Engineers, 1939This paper reviews the literature relating to the effect of temperature on the life of class A insulation. It presents test data on aging of built-up samples 100 mils thick, of varnished cloth, both black and yellow, over the temperature range 105 to 200 degrees centigrade.
