The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) instrument measures the intensity of atmospheric radiation emitted in the infra -red spectral region in five bands ranging from 685 cm to 2410 cm. Previous low spectral resolution observations of such infra-red emissions by the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) had revealed the presen...

The LLA Retina combines Lukasiewicz logic arrays (LLAs) with photo-sensor clusters to work as a fuzzy edge detection mechanism and several other applications. In this presentation we have explored various approaches to excite and evaluate the device with several types of light sources including visible and infra-red laser beams. Based on the detailed studies on the device, one particular config...

zinc ions are present in different types of industrial effluents, being responsible for environmental pollution. biosorption is a process in which solids of natural origin are employed for binding heavy metals. it is a promising alternative method to treat heavy metal wastes mainly because of high metal binding capacity. the effect of some important parameters on sorption capacity of cyanobacte...

Despite many advances during the last decade in both infra-red sensor and solid state camera technology, until now little headway has been made in the production of cost-effective semiconductor sensor arrays capable of operating far into the infra-red. Old ideas, renewed by the capabilities offered by the latest micromachine technology, may change all this. Reviews the problems associated with ...

Precision gas mixing pumps produce CO(2) gas mixtures for the calibration of infra-red CO(2) gas analyzers equivalent in accuracy to the standard CO(2) gas mixtures (+/- 1%) supplied by the National Bureau of Standards, Washington, D. C.The calibration of infra-red gas analyzers by the pressure difference method and by concentration differences did not agree. A factor of 0.709 was necessary to ...

In this paper, the infra-red absorption spectra of a number of crystalline natural estrogens are presented and considered in relation to chemical structure. As a group, the natural estrogens are distinguished chemically from other steroids by the benzenoid structure of Ring A, which gives rise to certain infra-red absorption bands by which their spectra may be differentiated from those of other...

In the context of a recently proposed method for computing exactly string loop corrections regularized in the infra-red, we determine and calculate the universal moduli-dependent part of the threshold corrections to the gauge couplings for the symmetric Z 2 ×Z 2 orbifold model. We show that these corrections decrease the unification scale of the underlying effective field theory. We also commen...
