-This paper discusses and compares HVDC ground electrode design methods in various soil structures. A number of cases are selected based on existing HVDC ground electrodes in order to compare the conventional simplified design method (Method A) with a more advanced grounding design method using a specialized engineering software (Method B). Various soil structures considered include horizontall...

The radar response of vegetated environments, and forested areas in particular, are usually modeled using a very simple structure made random volume, representing cloud vegetation particles, lying over semi-infinite medium with rough interface, associated the underlying ground. This Random Volume Ground model can efficiently handle double-bounce scattering mechanisms, or arbitrary volume reflec...

This paper describes a tank-scale test setup and experimental methodology used to investigate coupled heat transfer water flow processes during heating of compacted MX80 bentonite high temperatures. Specifically, temperature 200°C was maintained by cylindrical element at the center layer containing an array temperature, dielectric, relative humidity sensors. In addition providing evaluation spa...

In order to plan for global changing climate experiments are being conducted in many countries, but few have monitored the effects of the climate change treatments (warming, elevated CO2) on the experimental plot microclimate. During three years of an eight year study with year-round feedback-controlled infra-red heater warming (1.5/3.0°C day/night) and growing season free-air CO2 enrichment (6...

Wastes from agriculture or sewage systems have several properties, such as huge volume, high humidity, and high organic composition. According to past studies, sugarcane extract, peanut shells and rice husks have high silicon content. Chemical conversion of biomass feedstock will enhance usage and provide value to agricultural waste. In this research, we applied hydrothermal carbonization to co...

Aim of this work is looking for a correlation between footprint and soil penetration volume of treads in agricultural tires. Three tyres of different dimensions, fitted on the same tractor with different pressures and loads (N=not ballasted; Z=ballasted) were tested for defining the area of the single footprint shape (SF and SaF), of the multiple footprint shape (MF) and the volume of tyre in s...
