Wind induced ovalling vibrations were observed during a storm in October 2002 on several empty silos of a closely spaced group consisting of 8 by 5 thin-walled silos in the port of Antwerp (Belgium). In the present study, it is investigated if the observed ovalling oscillations can be numerically predicted. To this end, the silo structures are modeled using a finite element (FE) model and the w...

Two numerical algorithms are presented that couple a Boussinesq model of natural heat convection in two domains, motivated by the dynamic core of climate models. The first uses a monolithic coupling across the fluid–fluid interface. The second is a parallel implementation decoupled via a partitioned time stepping scheme with two-way communication. These new approaches are both proven to be unco...

This study was an attempt to investigate the effect of metacognitive strategies (MS) on speakingability of the learners and also what MS are specifically employed by learners when it comes todifferent task types. To this end, running a quasi-experimental study, 60 students at advancedlevel (female) from Shenia Language Institute in Sanandaj were randomly selected and given anOxford Placement Te...

Drivers' behavior is one of the most important factors in traffic safety. Understanding of this issue and its effective factors can be helpful to reduce the influences of human factors on traffic accidents. The objective of this study is to apply Manchester driver behavior questionnaire (DBQ) to a group of drivers who have overtaken on two-lane rural roads and to analyze their behavior. Also, t...

simulation of groundwater fluctuations plays a crucial role in management of watersheds and water demand balancing. recently, wavelet analysis has been used widely in time series decomposition and coupling with neural networks for hydrological modeling. in this paper, the ability of the wavelet-dynamic artificial neural networks (w-ann) model was applied in forecasting one-month-ahead of ground...
