Principles of the Generalized Spectroradiometry

Spectroradiometry of Spatially-resolved Solar Plasma Structures

The investigation of spatially-resolved solar plasma features in terms of radiometric measurements requires concepts different from those useful for full-Sun observations. After a definition of the relevant physical quantities, formulae are derived for studies of optically-thick and optically-thin plasmas observed with both spectral and spatial resolution. Simple examples of their applications ...

Nonstandard principles for generalized functions

We show that principles from nonstandard analysis hold to some extent for nonlinear generalized functions. The generalized functions under consideration are constructed as families of functions modulo a free filter, as it is usually done in applied analysis. In contrast with models of nonstandard analysis, we do not require the filter to be an ultrafilter. The principles are intended to be used...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Spectroradiometry for Solar Physics in Space

Realistic physical and chemical descriptions of the Sun require observations that have been made with spectroradiometrically calibrated telescopes and spectrometers, i.e., with instruments that have a known spectral responsivity. Such calibrations assure that a measured spectral radiance or irradiance is determined on a scale that is defined by the radiometric standards realised and used in lab...
