In this paper, using neural networks based on radial basis functions (RBF), a comprehensive closed-form solution for effective length of vertical grounding rod is extracted in such a way that the two effects of ionization and dispersion are simultaneously considered. In creating the model, training data are computed from multi-conductor transmission line (MTL). As a results, firstly in the prop...

Kerman and its surrounding towns consist of a flat alluvial plain of fine silt and clay materials. In morphological aspects, these sediments have a very gentle slope with the main infrastructure of the city build on them. Generally, the structure of undisturbed soils is developed over time due to the influence of environmental factors. Geological factors in Kerman fine-grained alluviums have ca...

The purpose of the research was to build information and analytical models soil based on data energy-dispersive X-ray fluorescence analysis. For Chelyabinsk region, basis experimental data, are constructed, showing a complete list chemical elements trace elements, content which exceeds permissible concentration. These models, clearly reflect micro-and macronutrients in soil, recommended for use...

An ideal engineered soil cover can mitigate acid rock drainage (ARD) by limiting water and gaseous O2 ingress into an underlying waste rock pile. However, the barrier layer in the soil cover almost invariably tends to develop cracks or fractures after placement. These cracks may change water flow and O2 transport in the soil cover and decrease performance in the long run. The present study empl...

Conventional Time-Frequency and Time-Scale Representations are often too rigid to capture fine details of sound or musical signals. Adaptation of ideal time-frequency tilings is often desirable in order to represent the signal in terms of components that are meaningful from a physical or perceptual point of view. Remapping of the time and frequency axes by means of time and frequency warping ca...

In order to limit the dispersive use of lead on small arms firing ranges, 5.56-mm bullets with tungsten-nylon composite material cores have been fired at a number of Army training ranges. Tungsten in bullet residues oxidizes when exposed to the atmosphere, yielding an amorphous tungsten oxide (WO3) coating. This coating rapidly dissolves to yield the tungstate anion (WO4), which can migrate in ...

Nanomaterials are used in practically every aspect of modern life, including agriculture. The aim of this study was to evaluate the effectiveness of iron oxide nanoparticles (Fe2O3 NPs) as a fertilizer to replace traditional Fe fertilizers, which have various shortcomings. The effects of the Fe2O3 NPs and a chelated-Fe fertilizer (ethylenediaminetetraacetic acid-Fe; EDTA-Fe) fertilizer on the g...
