BACKGROUND Pronated foot posture is associated with many clinical and biomechanical outcomes unique to medial compartment knee osteoarthritis (OA). Though shoe-worn insole treatment, including lateral wedges, is commonly studied in this patient population, their effects on the specific subgroup of people with medial knee OA and concomitant pronated feet are unknown. The purpose of this study wa...

in this article, vibration analysis of an euler-bernoulli beam resting on a pasternak-type foundation is studied. the governing equation is solved by using a spectral finite element model (sfem). the solution involves calculating wave and time responses of the beam. the fast fourier transform function is used for temporal discretization of the governing partial differential equation into a set ...

We present a simple atomistic model for the description of noncollinear coupling in magnetic multilayers with hybrid spacer layers made Ru alloyed to ferromagnetic atoms such as Fe. In contrast previous analytical and micromagnetic models that explain by means lateral fluctuations constant, presented accounts atom-atom all three spatial dimensions within layer. The is able accurately predict de...

During normal weight-bearing and locomotion, the equine hoof wall deforms in a consistent pattern; the proximal dorsal wall rotates caudo-ventrally about the distal dorsal border and there is latero-medial flaring posteriorly. The aim of this study is to examine whether there are regional differences in the modulus of elasticity of hoof wall material and whether such differences correlate with ...

Purpose This study aimed at finding out the effect of exit height, trajectory and number pins on stability cross divergent-lateral used in fixation extension-type, transverse supracondylar humerus fracture (SHF) children, based finite element analysis. Methods Distal model consisting ossific nucleus capitellum (ONC) distal cartilage a 6-year-old boy was developed via three-dimensional modeling....

Scapula neck fractures are rare injuries, leaving several treatment options. Standardized markers for operative treatment are a decreased glenopolar angle ≤22°, lateral border offset (LBO) of the glenoid ≥20 mm, angular deformity ≥45°, or LBO ≥15 mm plus angular deformity ≥35°. If operative treatment is not performed before union, the fracture heals malaligned with possible mechanical complicat...

This paper chronicles the research on the design, analysis, experimentation and application of a high efficient, low-power variable stiffness suspension system. The central concept is based on a recently designed variable stiffness mechanism which consists of a horizontal control strut and a vertical strut. The horizontal strut is used to vary the load transfer ratio by controlling the location...

One of the most important assumptions which is being used in analysis and design of buildings against lateral forces is the rigid-floor assumption. Lateral rigidity of diaphragms depends on several factors such as: type of the structure, dimensions of structure, rigidity and location of lateral load bearing elements, stiffness of frames, type and thickness of floors, number of stories and etc. ...

Recent investigations on the longitudinal and lateral control of wheeled autonomous vehicles are reported. Flatness-based techniques are first introduced via a simplified model. It depends on some physical parameters, like cornering stiffness coefficients of the tires, friction coefficient of the road, . . . , which are notoriously difficult to identify. Then a model-free control strategy, whic...
