The ETFs’ is a novel setting provides observable arbitrage activity attributed correcting mispricing between shares and their underlying assets. proxies for magnitude direction of speculative demand shocks use them form Speculatio...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
Growing scientific evidence indicates that synthetic plastic microbeads (hereafter, microbeads) are a threat to the environment and should be banned from all personal care products. Microbeads pollute the environment, adding to the increasing abundance of microplastic debris. Too small to be efficiently filtered by wastewater treatment processes, microbeads are found in aquatic habitats and fis...
In the past few years a lot of attention has been paid to the use of special logics to analyae cryptographic protocols, foremost among these being the logic of Burrows, Abadi and Needham (the BAN logic). These logics have been successful in finding weaknesses in various examples. In this paper a limitation of the BAN logic is illustrated with two examples. These show that it is easy for the BAN...
منطق اِحراز هویت باروز ابدی و نیدهام (ban) گام های مهمی در جهت تحلیل پروتکل های امنیت بر می دارد، و دارای چندین بازبینی پی در پی پیشرفته است. در این پایان نامه منطق های vo و svo را مطالعه می کنیم. vo یک گسترش از منطق های خانواده ban می باشد که برای اولین بار، بررسی کلید عمومی مبتنی بر پروتکل های ایجاد کلید اِحراز هویتی که هر دو عامل در اشتقاق کلید (یعنی، پروتکل های توافق-کلید) همکاری دارند را...
