in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...

abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...

Understanding the wave pattern as a first step in marine studies is very important. The global models as a source of data can be used to simulate local waves. Before applying them, their results should be evaluated. One of the most important global models is the ECMWF model. Based on the wave simulation in the northern coast of the Persian Gulf, it can be said that the ECMWF model results are o...
