This paper tries to examine literature as history, with an emphasis on the crucial role of fiction in narrating the marginalized events of history. Some fictions are actual accounts of events in history, and some are reflection of events. Actually, literature and history are integrated to each other, in a way that, pure history which shows us the reality and truth is just a myth. The pens writi...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
This paper develops probabilistic analysis approach to ensure generating capacity is sufficient to balance load (electricity demand) in power grid. In the future grid, most generation will come from variable sources, such as solar and wind. This means the grid can be only balanced probabilistically. Variability of renewable generation requires using storage, which must be a part of the analysis...
This research is prepared for studying the comparison of fear from evaluation of positive and negative events and quality of friendly behaviors in the nonclinical and normal social phobia affected people. This is a great comparison and a kind of observational case studies. The research statistical community is consisted of all social phobia affected and normal women (age 18-25) of Tehran Cit...
Maps of rates are often used for spatial dispersion analysis of certain event occurrence risk when data comes from counts by areas. However, the use of crude rates is associated to a high instability in expressing the risk of rare events in small population areas. As an alternative, will be introduced the empirical Bayesian rates; they make use either of the entire study region or the neighborh...
Extreme weather events are one of the main causes large-scale power outages in distribution systems. The changing climate has led to an increase frequency and severity these events, which, if not mitigated, expected lead more instances widespread severe societal economic damages that ensue. Protecting grid against such which high impact yet low frequency, requires a paradigm shift design practi...
