We used a binocular rivalry stimulus with one half-image having a vertical grating disk surrounded by horizontal grating, and the other half-image having a horizontal grating disk with a variable spatial phase relative to the surrounding horizontal grating. We found that increasing the phase-shift of the horizontal grating disk, which strengthens the boundary contour, progressively increases it...

It is well known that for laminated composite plates a Levy-type solution exists only for cross-ply and antisymmetric angle-ply laminates. Numerous investigators have used the Levy method to solve the governing equations of various equivalent single-layer plate theories. It is the intension of the present study to introduce a method for analytical solutions of laminated composite plates with ar...

PURPOSE We have tried to demonstrate whether the analysis of the muscle strain allows us to identify the three distinct functional areas of the architecture of the masseter, as one would see them by performing or viewing an anatomical dissection of said muscle, and whether these sections have behave differently in terms of origin and coping of the strain they face (quantitative analysis). MAT...

PURPOSE Tension band wiring is commonly used for fixation of simple transverse fractures. The popular configuration is parallel Kirschner wires (K-wires) and a stainless steel wire loop placed in a vertically oriented figure-of-8. METHODS We used a wooden model of a patella with a midway transverse fracture and compared four different types of fixation. The first construct had a vertical figu...

The motion of the striking point on the piano hammer was measured before and during string contact by means of an optical equipment. The measurements resolved the motion in two perpendicular components; in the striking direction (vertical), and in the string direction (horizontal). The influence of dynamic level and touch on the hammer motion was studied. Three different types of touch were eva...

Objetive: To compare the stresses and deformations generated on surrounding bone of zygomatic implants when using an intra sinusal extra-maxillary approach, through finite element method. Material Methods: Computer aided designs (CADs) were constructed SolidWorks Software a skull with resorption to be rehabilitated fixed hybrid prosthesis two conventional straight implants. For boundary conditi...

the accuracy and efficiency of the elements proposed by finite element method (fem) considerably depend on the interpolating functions namely shape functions used to formulate the displacement field within the element. in the present study, novel functions, namely basic displacements functions (bdfs), are introduced and exploited for structural analysis of nanobeams using finite element method ...

Through laboratory experiments we examine internal wave generation above and in the lee of finite-amplitude periodic topography having various degrees of roughness. We show that internal waves are generated not only by flow over the hills but also by flow over “boundary-trapped” lee waves and by vigorous turbulence created in the lee of sharp-crested hills. For low values of the excitation freq...
