Iteration method for simultaneous estimation of vertical profiles of air temperature and water vapor with the high spectral resolution of sounder of AQUA/AIRS data is proposed. Through a sensitivity analysis based on the proposed method for the several atmospheric models simulated by MODTRAN, it is found that the proposed method is superior to the conventional method by 41.4% for air temperatur...

Inefficient use of raw materials in most catalytic processes can be attributed mainly to the deactivation of the catalyst in chemical reactors. In order to achieve efficient use of raw materials, this paper addresses mitigation of deactivation through optimization of inlet temperature-time trajectories. The optimization of temperature profiles in reactors is one of the key problems in the synth...

All real processes generate entropy and the power/exergy loss is usually determined by means of the Gouy-Stodola law. If the system only exchanges heat at the environmental temperature, the Gouy-Stodola law gives the correct loss of power. However, most industrial processes exchange heat at higher or lower temperatures than the actual environmental temperature. When calculating the real loss of...

OBJECTIVE Leflunomide, an immunosuppressant agent for treating rheumatoid arthritis, was first marketed in France in 2000. Three years after its launch, we sought to assess its prescription patterns in the real world of prescription and use, and to see if its efficacy and safety profiles observed during clinical trials were confirmed. METHODS All patients treated with leflunomide from May 200...

introduction temporal and spatial change of meteorological and environmental variables is very important. these changes can be predicted by numerical prediction models over time and in different locations and can be provided as spatial zoning maps with interpolation methods such as geostatistics (16, 6). but these maps are comparable to each other as visual, qualitative and univariate for a lim...

In this paper we have studied the effect of free convection on the heat transfer and flow through variable porous medium which is bounded by two vertical parallel porous plates. In this study it is assume that free stream velocity oscillates with time about a constant mean. Periodic temperature is considered in the moving plate. Effect of different parameters on mean flow velocity, Transient ve...

The present paper aims at defining a simplified but effective model of a thermal network that links the thermal power generation with the resulting temperature time profile in a heated or refrigerated environment. For this purpose, an equivalent electric circuit is proposed together with an experimental procedure to evaluate its input parameters. The paper also highlights the simplicity of impl...

This study reevaluates the adiabatic temperature profile of Earth's mantle. The global average at 410-km discontinuity is estimated to be 1839 (38) K by comparing globally averaged depths with previously determined phase diagram olivine-wadsleyite transition in system (Mg,Fe)2SiO4 two temperatures. extrapolated shallower and deeper regions using gradient, which from pressure-volume-temperature ...

Water is important to all human and economic activity. Despite its abundant water resources, Malaysia's demand consumption was increased in recent years. This study had been investigating the condition of resources at present. aims identify by examining odour profile temperature intensity. E-Anfun E-nose applied generate a pattern volatile compounds included samples. The optimal correlation dis...

Abstract A plasma fluid model is being developed for the simulation of a direct current discharge including sheath regions. The code uses second order centered finite difference scheme and time integration done by strong stability preserving third Runge-Kutta method. separation scalar vectorial quantities in two different grids gives stable results. After validation comparison with theoretical ...
