iranian historiography during the safavid era affected by religious upheavals and intellectual and political developments, witnessed the emergence and evolution of a new approach towards time and techniques for recording history. the most important feature of this historiography was the continuance of pre-safavid models and regulations on the one hand, and the formation of typical safavid struc...

sorrow is one of the poetic subjects which is frequent since the ignorance period through elegiac poems which are full of kindness and sad motions. but since the recent & new era in particular since he romanticism era it gains progress in such a way that it does not only appear through the poetic couplets which illustrate an experience of poetic elegical sense, but also it becomes of potential ...

The 40-yr ECMWF Re-Analysis (ERA-40) data are analyzed to demonstrate that wave forcing at lower latitudes plays a crucial role in driving the tropical upwelling portion of the Brewer–Dobson circulation. It is shown that subtropical wave forcing is correlated with tropical upwelling on both intraseasonal and interannual time scales when transient waves are taken into account, and that tropical ...

[1] The energy input to the upper ocean Ekman layer is assessed for the Southern Ocean by examining the rotary cross spectrum between wind stress and surface velocity for frequencies between 0 and 2 cpd. The wind stress is taken from European Center for Medium-Range Weather Forecasts ERA-40 reanalysis, and drifter measurements from 15 m depth are used to represent surface velocities, with an ad...

We are now in the post-PC era, yet our mobile devices are insecure. We consider the different stake-holders in today’s mobile device ecosystem, and analyze why widely-deployed hardware security primitives on mobile device platforms are inaccessible to application developers and end-users. We systematize existing proposals for leveraging such primitives, and show that they can indeed strengthen ...

Sadra views essential defect of human soul, coverage, imitation or following the group and the effect of corporeality as the agents against the human system of reasoning and, therefore, lead to human inclination from ethical values. For Molla Sadra, nearly all of immoralities lie in the lack of knowledge and in the negligence caused by irrational powers dominating human system of reasoning. In ...

To my family in China and my wife Yun ACKNOWLEDGEMENTS I wish to thank Prof. Robert Dickinson for advising my thesis and providing support for my PhD study for the past five years. This dissertation would be impossible without his continuous encouragement and support. I am grateful to the support and help from and discussions with Prof. Albany). I also like to thank my current and past group me...

A new nonparametric method to correct model data is proposed. At any given point in space and time the correction is determined from “analogs” in a learning dataset. The learning dataset contains model data and simultaneous observations. The method is applied to the significant wave height dataset of the 45-yr European Centre for Medium-Range Weather Forecasts Re-Analysis (ERA-40). Comparison o...
