Background: Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur’s geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (ST...

in this paper, the enhancement of vehicle stability and handling is investigated by control of the active geometry suspension system (ags). this system could be changed through control of suspension mounting point’s position in the perpendicular direction to wishbone therefore the dynamic is alternative and characteristics need to change. for this purpose, suitable controller needs to change mo...

in this study, thermoplastic polyolefin elastomeric (tpo) nanocomposites were fabricated by friction stir processing. the effect of different pin geometries on clay dispersion and mechanical properties of the tpo nanocomposite reinforced with 3% wt nanoclay has been first investigated. the optimum pin geometry namely threaded cylindrical pin was then used to fabricate the nanocomposites contain...

islamic arts are often identified by their abstract compositions based on geometric principles and spiritual concepts. using artworks from different eras, this paper highlights the presence of a particular model of thought in islamic arts in which the hierarchy of perspectival vision is abolished. the main argument is based on the ability of some artworks to be looked at from any angle while ma...
