Simply supported bridges comprise the majority of bridge systems in coastal communities and are susceptible to severe damage from extreme waves induced by storms or tsunamis. However, effects oblique wave impacts have been less investigated due lack appropriate numerical models. To address this issue, study investigates incident angles on superstructures developing an advanced computational flu...

The Necker cube is a striking example for perceptual dominance of 3D over 2D. Object symmetry and obliqueness of angles are co-varying cues that may underlie the perceived slant of Necker cubes. To investigate the power of the oblique-angle cue, slants were judged of extremely simple symmetrical shapes. Slant computations based on an assumption of orthogonality were made for two abutting lines ...

An increasing number of airborne image acquisition systems being equipped with multiple smallor medium size frame cameras are operational. The cameras normally cover different viewing directions. In contrast to vertical images, those oblique images have some specific properties, like a significantly varying image scale, and more occlusion through high raising objects, like buildings. However, t...

Purpose: The aim of the study is to determine stress distribution on preloaded implant-abutment screws in three different implant systems under simulated occlusal loads. Materials and methods: Three abutments to implant internal hex joint systems were simulated by using the 3-dimensional finite element analysis; (1) Nobel Biocare replace tapered (2) Uniti (3) Lifecare self-threaded tapered ceme...

Most subduction zones on Earth are oblique, i.e., the angle between plate convergence vector and trench notably differs from 90°. Therefore, modeling understanding strain partitioning in forearc, development of extensional basins back-arc region diachronous transition to collision require a 3D approach. Here, we assess how oblique oceanic subsequent associated mantle flow around subducted litho...

the purpose of this ex- vivo study was to evaluate the fracture resistance of simulated immature teeth, obturated with gutta-percha or resilon and reinforced by either composite resin or fiber post.eighty-four human maxillary incisors were divided into seven groups (n=12). teeth in all groups were prepared until peeso #5 (1.5mm) could be passed through the apex. root ends received 4mm of mta pl...

AIM This study aimed to compare the stresses generated by using two or four root form dental implants supporting mandibular overdentures that were retained with ball and locator attachments. METHODS Under ANSYS environment, four 3D finite element models were prepared. These models simulated complete overdentures supported by two or four implants with either ball or locator attachments as a co...
