Environmentally specific mechanical properties: Beyond atomic parameters

Physical Review B, 1988
Representative wave functions of Cu, ${\mathrm{Ir}}_{3}$Cr, and ${\mathrm{Zr}}_{3}$Al as determined from multiple-scattering $X\ensuremath{\alpha}$ cluster calculations are compared. While atomic parameters, specifically $s$-orbital electronegativities, predict an isotropic charge density for ${\mathrm{Ir}}_{3}$Cr and an anisotropic charge density for $

Estimating return values of environmental parameters

Quarterly Journal of the Royal Meteorological Society, 1981
AbstractReturn values of an environmental parameter, such as wind speed or wave height, are frequently estimated from an extreme value analysis of observed annual maxima assuming that the parameter is identically distributed throughout the year. Environmental data generally have considerable within‐year variation.

Environmental and Hazard Parameters

2011
This section describes the foundational information collected for identifying typical/standard fire and smoke scenarios, likely false/nuisance scenarios, and a range of ambient conditions to which VID systems may be subjected in the three target applications.

Environmental Parameter Control of the Greenhouse

2013 Fifth International Conference on Measuring Technology and Mechatronics Automation, 2013
Aiming at the high-precision mechanism model of the greenhouse and the problem of the nonlinear strong coupling between temperature and humidity, this paper employs the method of accurate linearization in the nonlinear system. The exact linearization of the system is realized through state feedback", "and then realizes the gradual tracking of the ideal

Frost Formation With Varying Environmental Parameters

Journal of Heat Transfer, 1975
In practical applications frost formation often takes place with varying environmental parameters (air velocity, temperature, and humidity). Most correlations that have been developed are for constant parameters. Since the frost formation process is dependent on both time and on the history of the frost layer, the correlations for constant ...

Multifunctional Sensor to Detect Environmental Parameters

2007
The SIRPA project aims at developing a multifunction automotive sensor with the integration, on a single CMOS array, of several sensing functions presently provided by different sensors. Such multifunctional sensor will be used to detect a number of critical environmental parameters, such as the luminance of the background and the visibility (in the ...

Moose teeth as monitors of environmental isotopic parameters

Oecologia, 1990
The radiocarbon activities of amino acids isolated from crown first molar dentin of moose born between 1948 and 1984 on Isle Royale National Park, USA closely follows the bomb radiocarbon signal generated from atmospheric nuclear weapons testing. This demonstrates that these amino acids are metabolically inert and have recorded the isotopic parameters ...

Methods for measuring environmental parameters

Вісник Національного технічного університету «ХПІ». Серія: Механіко-технологічні системи та комплекси, 2014
В статті виконано аналіз кількісних методів вимірювання параметрів навколишнього природного середовища, до яких відносяться хімічні, фізико-хімічні, фізичні та біологічні методи. Здійснено класифікацію кожного із зазначених методів кількісного аналізу. Визначені умови та межі застосування даних методів. Показано їх основні переваги та недоліки.
