This paper summarizes the results from microclimatic monitoring of impacts related to construction and exploration phase a hydroelectric powerplant in upper Douro River (Portugal). Reference climatic elements for both periods were obtained reservoir water mass on region’s microclimate evaluated. For this purpose, Sen’s slope estimate non-parametric test was used detect meteorological variables’...

The aviation industry is facing the challenge of reducing fossil fuels and emissions. Fuel efficiency improved by making efficient powerplant systems lighter aircraft. Modern passenger aircraft utilize polymeric composite materials to achieve structures without compromising strength. European Union already has legislation prevent landfilling increase use recyclable in automotive industry. While...

Levy et al. (2002) describe portions of their analysis of the public health impacts of emissions from nine power plants in Illinois. This and similar analyses (Levy and Spengler, 2002; Freeman, 2001; Abt, 2000) use dataintensive models of air quality and health risks to estimate the number of deaths caused by increases in ambient particulate matter (PM) concentrations due to emissions from spec...

Nearpt3 is an algorithm and implementation to preprocess more than 10 fixed points in E and then perform nearest point queries against them. With fixed and query points drawn from the same distribution, Nearpt3’s expected preprocessing and query time are θ(1), per point, with a very small constant factor. The data structure is a uniform grid in E, typically with the same number of grid cells as...

The wavelet variability model (WVM) for simulating solar photovoltaic (PV) powerplant output given a single irradiance sensor as input has been developed and validated previously. Central to the WVM method is a correlation scaling coefficient ( ) that calibrates the decay of correlation of the clear sky index as a function of distance and timescale, and which varies by day and geographic locati...

Acid soils with pH values below 5.5 have a negative effect on agricultural production. For this reason, liming is applied as measure to raise the soil optimum (pH = 6–7). The aim of our research was evaluate and compare effectiveness four materials (wood ash from biomass powerplant, filter dust cement factory, blast furnace slag iron carbocalk (limestone, by-product sugar factory)) in combinati...
