Dike height optimization is of major importance to the Netherlands since a large part of the country is below sea level and high water levels in rivers may cause floods. In this paper we propose a cost-benefit analysis to determine optimal dike heights. We improve the model proposed by Van Dantzig (1956) after a devastating flood in the Netherlands in 1953. For one important class of the dike i...
Use the Spur dike as one of the easiest ways to protect the costal of the river has always been of interest to River engineers.The aim of this study was numerical investigate, the effect of distance and angle of the spur dikes parameters on the pattern of distribution of average velocity and the location of maximum velocity position at a mild 90 degree bend. For this purpose used ANSYS CFX so...
Introduction: Partial melting occurs in planetary bodies due to (1) temperature rise as heat is produced from radioisotope decay; or decompression as parts of the mantle rise due to (2) thermal convection or (3) overturn driven by compositional instability. Case (1) dominated early-forming differentiated asteroids heated by short half-life isotopes [1, 2] but is not relevant to the Moon. There ...

even though, to date, a lot of studies have been conducted on the subject of politeness theory, there are very few studies regarding the applicability of this theory to translation between english and persian which shows the reason behind conducting the present study. this study was carried out with the aim of highlighting whether there is any difference between english and persian methods of u...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Imnaha Basalt and Grande Ronde Basalt (RI) of the Columbia River Basalt Group form a small synclinal basin immediately west of Riggins, Idaho. The displacement of the margins of the basalt outcrop, of the synclinal axis, and of a dike of Saddle Mountains(?) Basalt define a pattern best explained by a model of west-northwest to eastsoutheast and north-northwest to south-southeast dextral strike-...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
colonialism is an important factor in cultural production and many of cultural constructs all over the world. english and english language teaching are at the center of the contemporary world. postcolonial literature, the genre achebe exercised, is a kind of historical text which has become central to different debates and criticisms. in this thesis, different elements related to the colonial...
