Numerical simulation of an ever-increasing range of geophysical phenomena is adding enormously to our understanding of complex processes in the Earth system. The consequences for mankind of ongoing climate change will be far-reaching. Earth System Models are capable of replicating climate regimes of past millennia and are the best means we have of predicting the future of our climate. The basic...
‘romanticism’ and ‘romantic’ are among the most controversial terms in literature. most readers, when encountering these words, would think of the well-known period of romanticism of the first three decades of the nineteenth century and the great six english poets known as ‘the big six’ of this period. however, romanticism does not belong to certain artists in a special period; one may seek ele...

dynamic behavior of ground supported cylindrical storage tanks (cst) is of crucial importance because of its applications in industrial complexes. seismic behavior of tanks is greatly affected by the height to diameter ratio, fluid height and fluid type. five csts with different height to diameter ratios, three csts with the same height and diameters but various fluid heights and one cst with t...
The paper gives an overview of our previous results concerning heat kernel measures in infinite dimensions. We give a history of the subject first, and then describe the construction of heat kernel measure for a class of infinite-dimensional groups. The main tool we use is the theory of stochastic differential equations in infinite dimensions. We provide examples of groups to which our results ...
chapter one is devotod to collect some notion and background informations, which are needed in the next chapters. it also contains some important statements which will be proved in a more general context later in this thesis. in chapter two, we show that if the marginal factor-group is of order np1...pk,n>1, then we obtain a bound for the order of the verbal subgroup. also a bound for the bear-...
در این پایان نامه یک نوع آنتن ویوالدی آنتیپودال متقارن مورد تحلیل، طراحی و شبیه سازی قرار گرفته شده است و نتایج آن از جمله گین ، تلفات برگشتی و قطبی شدگی متقاطع و در نهایت پترن آن در رنج فرکانس 1 تا 20 گیگاهرتز ارائه گردیده است. ابتدا انواع آنتن ویوالدی و روند سیر تکامل آن مورد بررسی قرار گرفته و با توجه به مزایا و کاربردهای آن،یک نوع آنتن ویوالدی دو طرفه متقارن انتخاب شده و مورد تحلیل و بررسی...
