Field-emission patterns from a clean tungsten tip apex induced by femtosecond laser pulses have been investigated. Strongly asymmetric field-emission intensity distributions are observed depending on three parameters: (i) the polarization of the light, (ii) the azimuthal, and (iii) the polar orientation of the tip apex relative to the laser incidence direction. In effect, we have realized an ul...

We designed an emission control driver using P-type TFTs to adjust the light emission period of an active matrix organic light emitting diode (AMOLED) displays. The P-TFT emission control driver has achieved rail-to-rail driving and low power consumption. Using this circuit, we can control peak brightness dynamically to reduce panel power consumption and motion blur. We developed 4.3 inch WQVGA...

Artificial intelligence-based hardware devices are deployed in manufacturing units and industries for emission gas monitoring control. The data obtained from the intelligent analyzed at different stages standard emissions carbon This research article proposes a control-centric classification technique (CDCT) analyzing as well controlling pollution-causing units. AI observe intensity, rate, comp...

In the Persian Gulf region, conditions are highly favorable for ozone air pollution and the region is a hot spot of photochemical smog. The vast activities in processing oil and gas play a major role in it. It was found that the elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from Hydrocarbon Processing facilities lead to substantial ozone production. South Pars...

This article presents the research results on production and performance of palladium-only catalytic converters. Monolith is used as the catalyst carrier and gamma alumina as the substrate. Dipping method is used for monolith washcoating. Palladium as the active metal is impregnated on gamma alumina using wet impregnation to produce catalyst samples. The effects of factors such as percent solid...

The paper addresses the issue of control of world technological development under prescribed constraints on the emission of greenhouse gases. We use a stylized mathematical model of the world GDP whose growth leads to the increase of industrial emission provided investment in “cleaning” technology is insufficient. The proportion between investment in industrial technology and investment in “cle...
