earth dam is a structure as homogeneous or non-homogeneous forms for raising water level or water supply. earth dam consist of different parts that one of the main parts is clay core. choosing an optimal non permeable core which causes reduction of seepage through dam body and also being stable is necessary. the objective of this research is to optimize the geometry of earth dam clay core such ...

Our selection of new super greenhouse gases to fill a putative "window" in a future Martian atmosphere relies on quantum-mechanical calculations. Our study indicates that if Mars could somehow acquire an Earth-like atmospheric composition and surface pressure, then an Earth-like temperature could be sustained by a mixture of five to seven fluorine compounds. Martian mining requirements for repl...

one of the difficulties in using absolute altitudes is the separation between the mean open sealevel and geoid. theoretically, geoid is the base level in absolute altitudes, but practically, the mean open sealevel is used as a base level for absolute altitudes. the difference between these two levels is called as the seasurface topography. in this research, it is dealt the mean sea level modeli...

The Community Earth System Model (CESM) is a flexible and extensible community tool used to investigate a diverse set of Earth system interactions across multiple time and space scales. This global coupled model significantly extends its predecessor, the Community Climate System Model, by incorporating new Earth system simulation capabilities. These comprise the ability to simulate biogeochemic...

Parallel processing has tremendous potential, but has been disappointing in practice. One reason is that parallel computer designers cannot a ord to put the same resources into building processors as the makers of commodity chips, who command a much larger market. Therefore, most parallel architects have turned to o -the-shelf microprocessors, which do not support parallel processing well. Mult...

The previous paper presented at the 2016 FCRAR discussed the research topic of creating time simulating solar system models. This paper is an overview of the work done over the passed year in solar system model creation and the potential future work in STEM education. The use of designed tools to assist with relating abstract ideas to reality is now a possibility with the use of the modern manu...
