This paper is a preliminary report on the results of an investigation into the diffusion of Euclidean shape, using computer algebra to reduce complicated intermediate calculations to an informative final form. The computer algebra takes the form of an extension to the symbolic Itô calculus described in W.S. Kendall (1988). A substantially more detailed treatment (including details of how to obt...

The Discrete Element Method (DEM) was used to investigate the micromechanics of adhesive units, building blocks mixtures, comprising a carrier particle with attached micronised fine particles. Binary head-on collisions between units performed in handling and dispersion velocity regimes, variations mechanical properties (mannitol or lactose) size (50, 100, 200 ?m). system modeled spherical parti...

The rapid growth of staphylococci in the usual laboratory media consisting of meat infusion or meat extract, peptone, buffer, and metabolizable carbohydrate is accompanied by the consumption of sugar and the production of much acid; only relatively slight changes are noted in the nitrogenous constituents (Kendall, Farmer, Bagg, and Day (1)). Kendall, Friedemann, and Ishikawa (2) obtained a yiel...

The primary goal of this study is to comprehend the effects El Niño Southern Oscillation (ENSO) climate pattern on groundwater storage (GWS) in South Atlantic-Gulf Region. Groundwater issues are complex and different studies focused depletion while few emphasized “groundwater rise”. current research designed develop an outline for assessing how patterns can affect fluctuation, which might lead ...

The rapid growth in the world population resulted an increase of freshwater needs many sectors. Groundwater is most important source specially for arid and semi-arid regions due to lack surface water sources low precipitation rates those regions. In this study, monthly groundwater quality data were collected from eleven well fields Sharjah over period 2004-2017. Water parameters including bicar...

Climate is a crucial determinant of an area's vegetation, wildlife, and livability, influenced by long-term atmospheric characteristics fluctuations. Precipitation, particularly rainfall, plays vital role in the Earth's hydrological cycle, connecting weather, climate, water resources. This study focuses on Rajnandgaon district Chhattisgarh, India, with average annual precipitation 1274mm. Analy...

introduction: studying long-term trend changes of meteorological parameters is one of the routine methods in atmospheric studies, especially in the climate change subject. among the meteorological parameters, temperature is always considered as one of the most atmospheric elements and studying it in order to gain a better understanding of the climate change phenomenon, has been effective. in ad...

the purpose of this study is estimation of daily value at risk (var) for total index of tehran stock exchange using parametric, nonparametric and semi-parametric approaches. conditional and unconditional coverage backtesting are used for evaluating the accuracy of calculated var and also to compare the performance of mentioned approaches. in most cases, based on backtesting statistics results, ...
