the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...
The curvature of the sea wave was tested as a parameter for estimating wave direction in the search for better results in estimates of wave direction in shallow waters, where waves of different sizes, frequencies and directions intersect and it is difficult to characterize. We used numerical simulations of the sea surface to determine wave direction calculated from the curvature of the waves. U...
This article focuses on techniques for position reconstruction of acoustic point sources with the AMADEUS setup consisting of 36 acoustic sensors in the Mediterranean Sea. The direction reconstruction of an acoustic point source utilizes the information of the 6 small-volume hydrophone clusters of AMADEUS individually. Source position reconstruction is then done by combining the directional inf...
introduction the dynamic state index (dsi) is being introduced on the basis of a newly developed theory termed the energy-vorticity theory (evt). as a weather index, the dsi can describe the temporal sequence and intensity of areas of high and low pressure; but as a climate index, it can also diagnose climate change based on the variation in solar radiation or the influences of friction. in phy...
چـکـیده مقدمه: در طول دو دهه ی اخیر بخش قابل توجهی از تمرکز سازمان ها بر روش های مدیریت هزینه ها (cost management)، و رشد درآمدها (revenue growth) معطوف گشته است. توجه صرف به مدیریت هزینه یا رشد درآمد به مفهوم از دست دادن فرصت بهره مندی از دیگری است. به این ترتیب چیزی که لازم به نظر می رسد ایجاد توازن و هماهنگی بین این دو می باشد؛ اما چگونه این توازن اتفاق می افتد؟ ارزیـابی ارزش هر مشتری، تخ...
