power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
Water vapor jet assisted metal cutting is a pollution-free green cutting technique. This paper has developed a three-dimensional finite element model of water vapor jet assisted cutting in order to understand the influence of its cooling and lubricating effect on cutting process. The cooling effect of water vapor jet is modeled with a convective heat transfer coefficient. A window with the temp...
[1] At present, two Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on board the NASA Terra and Aqua Spacecraft platforms are operational for global remote sensing of the land, ocean, and atmosphere. In this paper, we describe an algorithm for water vapor derivations using several MODIS near-IR channels. The derivations are made over areas that have reflective surfaces in the ...
A dual frequency ground-based radiometer operating in the 1 to 1.4 cm wavelength range can provide continuous measurements of integrated water vapor and cloud liquid water. Using climatological data, the accuracy of the vapor and liquid determinations is estimated as a function of cloud amount. Limiting factors in the water determination are uncertainties in water vapor absorption coefficients ...
We show here that stratospheric water vapor variations play an important role in the evolution of our climate. This comes from analysis of observations showing that stratospheric water vapor increases with tropospheric temperature, implying the existence of a stratospheric water vapor feedback. We estimate the strength of this feedback in a chemistry-climate model to be +0.3 W/(m(2)⋅K), which w...
Computer generated images of the earth are often used for space flight simulators, computer games, movies, and so on. Clouds are indispensable to the creation of realistic images in these applications. This paper proposes a method for animating clouds surrounding the earth. The method allows the user to control the motion of clouds by specifying the center positions of high/low atmospheric pres...
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
ENSC 461 (S 11) Gas Vapor Mixtures and HVAC 1 Gas Vapor Mixtures and HVAC Atmospheric air normally contains some water vapor (moisture). The dry-air contains no water. Although the amount of water vapor in the air is small, it plays a major role in human comfort and thus in air-conditioning applications. The temperature of air in air-conditioning applications ranges from about -10 to 50°C. In t...
now-a-days graphic design plays a major role in influencing culture, society, business, and customers, in such a way that one could look upon every individual as a potential customer. graphic designers seek to identify customers needs and find an intelligent solution for them. correct identification and understanding of those needs is the first step towards achieving ones goals. marketing knowh...
