In studying the dynamics of ant nest excavation, the nest volume has to be continuously monitored. In many laboratory studies, the excavated substrate, such as sand, was collected, and the volume of excavation was calculated by converting the weight of the collected sand into the volume. The excavated sand can be manually collected and weighed; however, manual collection is tedious, particularl...

Sandstorm has an effect on the electric field characteristics of outdoor insulator, and may result in flashover. The analysis of the electric field characteristic of insulator under sandstorm condition is very important. The electrostatic field finite element method (FEM) is used to calculate the electric field distribution along long rod insulator under sandstorm condition with FEM software. T...

We analyzed patterns of sand deposit distribution on the reef platform, and documented relationships between sand deposits and reef morphology. Sand deposit patterns, the surrounding morphology, and the environments they are located in are best understood using a combination of statisitics, GIS software, spatial analysis tools, and analyst interpretation. The work consisted of several steps inc...

Sand drawings form a part of many cultural traditions. Depending on the part of the world in which they occur, such drawings have different names such as sona, kolam, and nitus drawings. In this paper, we show connections between a special class of sand drawings and mathematical objects studied in the disciplines of graph theory and topology called Gaussian graphs. Motivated by this connection,...

In order to recognize the wind erosion situation of a region, the survey of its windiness is not sufficient and the physical characteristics of earth are of importance too. In fact, the outbreak of dust storms in a region is due to the sensitivity of earth and domination of wind in that region. In this investigation we have tried to find a way for determining the regions in which a dust storm i...
