A controllable energy method, which considers the undersampling issue of transfer function and valid spectral a source signal, is proposed to implement angular spectrum diffraction calculation in near far fields. The method provides an optimized frequency boundary fCE within it always keeps be diffracted. significantly reduces number samples while having same accuracy as previous methods, imply...
Background and objective: numerous seismic hazard analysis studies are conducted annually using probabilistic methods throughout the world and Iran, which are usually different from the initial assumptions of analysis or software used. On the other hand, many researches are presented every year about new methods of earthquake hazard zoning, but so far these studies have not computed earthquake ...
روشهای طراحی مقاوم در برابر زلزله، در اکثر کشورهای پیشرفته دنیا در حال تغییر می باشد. خرابی بیش از حد انتظار زلزله های اخیر کشورهای پیشرفته مانند ایالات متحده ژاپن، و ضعف روشهای فعلی آیین نامه های در برآورده کردن اهداف طراحی مقاوم در برابر زلزله را روشن ساخته است. به منظور بر طرف ساختن کاستیهای روشهای موجود، روش طراحی عملکردی (performance based design) توسط محققین معرفی و توصیه شده است. از ...
PT. ABC is a company engaged in the manufacture of Dolomite Fertilizer. The number requests greater than amount production. Due to fluctuations that tend increase, this occurs due lack capacity at workstation. Therefore, it necessary calculate requirements planning analysis for each work station know company's needs. research aims identify shortage/excess production and provide proposals balanc...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
This paper reviews recent work on spread spectrum network capacity. The network is shown to have a capacity that is equitably shared amongst the users via power control. This solution is much simpler than the bandwidth partitioning of the FDMA/reuse approach. The capacity gains from using spread spectrum, arising from the averaging and multiplexing, are also emphasised.
