williams, watts, macleod and mathews' (1988) model of anxiety and depression leads to the prediction that anxious patients will show mood – congreuent implicit memory bias, while depressed patients will show mood-congruent explicit memory bias.although this prediction has been supported by some researchers (denny & hunt, 1992 mathews, moog, et al , 1989 watkins, et al, 1992), the reliabili...
We present a unified framework for separating specular and diffuse reflection components in images and videos of textured scenes. This can be used for specularity removal and for independently processing, filtering, and recombining the two components. Beginning with a partial separation provided by an illumination-dependent color space, the challenge is to complete the separation using spatio-t...
چکیده با توجه به زلزله های گذشته، آسیب های وارده به قسمت های مختلف پل شامل، روسازه ها، نشمین گاهها، پایه های پل، اتصالات، فونداسیون، دال های دسترسی، دیافراگم های عرضی، شاه تیر ها، تیر های سرستون و آسیب های غیر سازه ای می باشد. در حال حاضر یکی از مهمترین اهداف مهندسان زلزله پیش بینی رفتار سازه ها در برابر زلزله های آینده است. اطلاعات محدود، در مورد پارامترهای لرزه ای از قبیل فاصله از مرکز زلزل...
A major challenge for users of enterprise information is finding the information they want, presented in a way that makes sense to them. In this paper we tackle this problem by creating adaptive user profiles from implicit behaviour. In traditional approaches to information filtering, the user has to explicitly create his or her profile, and manually keep the profile up to date. Taking advantag...
زلزله به عنوان یک پدیده طبیعی ویرانگر است که هر ساله قسمتی از زمین را می لرزاند و خرابی به بار می آورد. جهت کاهش این خسارت، احداث ساختمان های مقاوم در برابر زلزله و بهسازی ساختمان های موجود لازم بوده و برای رسیدن به این هدف، آگاهی از چگونگی رفتار سازه های موجود ضروری است. تحلیل دینامیکی افزایشی (incremental dynamic analysis) روشی است که اخیراً مورد توجه قرار گرفته و می تواند رفتار سازه را با افز...
In this work, coupled numerical analysis of interacting acoustic and dynamic models is focused. In this context, several numerical methods, such as the finite difference method, the finite element method, the boundary element method, meshless methods, and so forth, are considered to model each subdomain of the coupled model, and multidomain decomposition techniques are applied to deal with the ...
A procedure to build up a dynamical model of the gearbox with spur involute mesh is being described. The main attention is paid to the design technology of the cylindrical bodies elastic contact models. To track geometry of contact implicit equations of algebraic/transcendental or differential-algebraic type are being used. At the same time dynamical models of the bodies involved, gearwheels an...
algal growth and the water quality effects were studied and modeled in the lower reaches of the colusa basin drain as a stream system. statistical techniques such as the correlation matrix and the stepwise multiple regression are performed on such variables as algal biomass, ammonia, nitrate, orthophosphate, temperature, and the solar radiation intensity in deriving an algae statistical model. ...
the paper investigates into the vibrational characteristics of the truck chassis including the natural frequencies and mode shapes. truck chassis forms the structural backbone of a commercial vehicle. when the truck travels along the road, the truck chassis is excited by dynamic forces caused by the road roughness, engine, transmission and more. modal analysis using finite element method (fem) ...
In [9] we presented an approach to permission-based reasoning about concurrent Java programs in the context of the interactive program verifier KeY [1] which is based on Dynamic Logic and explicit dynamic frames [6, 13]. We argued for the explicit approach advocating the modular use (w.r.t. sequential vs. concurrent) and overall preciseness. It was noted, however, that changing our specificatio...
