تعیین بسیاری از مشخصات و رفتار بتن تابع اجزای تشکیل دهنده ی آن می باشد. و برای اینکه بتوانیم نحوه ی ترک خوردگی و تأثیر مشخصات مکانیکی و هندسی اجزای بتن را روی رفتار آن مدل کنیم لازم است که بتن را بصورت غیرهمگن مدلسازی کنیم. غیرهمگنی بتن را در مقیاس های مختلف ماکروسکوپی، میکروسکوپی و یا میان مقیاس قابل بررسی است. در یک بررسی میان مقیاس بتن به عنوان یک ماده غیر همگن سه فازه مشتمل بر سه فاز سنگدان...
This article considers the hypothesis that media-driven political interest shapes party identification, the timing of vote decisions, and electoral participation. To estimate the effect of media-driven political interest, we make a key distinction between political interest as a lifetime political orientation and political interest that rises and falls with the occurrence of noteworthy politica...
Accurate estimates o f kill rates remain a key lim itation to addressing many predator—prey questions. Past approaches for identifying kiU sites o f large predators, such as wolves {Canis lupus), have been lim ited primarily to areas w ith abundant w inter snowfall and have required intensive ground-tracking or aerial monitoring. M ore recently, attem pts have been made to identify clusters o f...
The creation and development of a large Lexical Database (LDB) which, until now, mainly reuses the data found in standard Machine Readable Dictionaries, has been going on in Pisa for a number of years (see Calzolari 1984, 1988, Calzolari, Picchi 1988). We are well aware that, in order to build a more powel-ful I.DB (or even a Le.'dcal Knowledge Base) to be used in different ComputationM l.ingui...
حوزه بررسی سازه های بتنی فرض میشود که بتن یک ماده همگن است در صورتیکه در اصل بتن شامل اجزا مختلفی مانند خمیر سیمان، سنگدانه شن ،ماسه، و هوا میباشد که وجود این اجزا در تعیین رفتار بتن حائز اهمیت است لذا برای بیان اثرات ساختار بتن بر روی رفتار درشت بینی آن نیاز به استفاده از مدل در مقیاس ریز بینی خواهیم داشت. در مدلهای اولیه، بتن بصورت دو فاز شامل سنگدانه و خمیر سیمان در نظر گرفته می شد اما تحقیق...

Grammar development environments (GDE's) for analysis and for generation have not yet come together. Despite the fact that analysis-oriented GDE's (such as ALEP) may include some possibility of sentence generation, the development techniques and kinds of resources suggested are apparently not those required for practical, large-scale natural language generation work. Indeed, there is n o u s e ...

CHEMTAX is a matrix factorization program used to derive taxonomic structure of phytoplankton from photosynthetic pigment ratios. The program was originally developed from and applied to the analysis of oceanic phytoplankton assemblages. We found that application of the original CHEMTAX reference matrix to southeastern United States estuarine systems produced inaccurate results, as verified by ...
This paper explores a paradox: negative correlations between indicators of mobility (such as VMT) and productivity (such as GDP), and positive correlations between mobility constraints (higher road use prices or traffic congestion) and productivity. These relationships contradict common assumptions that policies and projects that increase vehicle travel (roadway expansions and lower road user p...
