Abstract: In this paper, the forming process of a central hub by radial-forward extrusion is analyzed by using the finite element software, ABAQUS. Radial-forward extrusion is used to produce hollow parts that generally feature a central hub with radial protrusions. Effective design factors such as mandrel diameter, die corner radius, die fillet radius, mandrel corner radius, tube wall thick...

background: fractures of distal radius are one of the most common fractures seen by physicians and account for 20% of all fractures seen in the emergency room. various factors contribute in secondary displacement of fracture fragments after anatomic or near anatomic close reduction and cast immobilization in distal radius fractures. this study was designed to examine the correlation between rad...

background: radial movement of the arterial wall is a well-known indicator of the mechanical properties of arteries in arterial disease examinations. in the present study, two different motion estimation methods, based on the block-matching and maximum-gradient algorithms, were examined to extract the radial displacement of the carotid artery wall. methods: each program was separately implement...

results overall, there were 2 (2.7%) mason ii fractures, 21 (28%) mason iii fractures, and 52 (69.3%) mason iv fractures. arbeitsgemeinschaft fur osteosynthesefragen (ao) classification was also determined. of the 85 patients in our study, 75 were available for follow-up. follow-up averaged 41.5 months (range, 4 - 93 months). average scores for the cohort were as follows: morrey, 85.7 (median 9...

background: to evaluate the intermediate-term outcomes of radius shortening as a treatment for kienbock’s disease. materials and methods: in a historical cohort, 16 skeletally mature patients (9 men and 7 women) with kienbock disease, who were treated with radial shortening osteotomy between 2002 and 2012, were reviewed in our study. the mean age of our patients was 30 (range 18-43) years old. ...

A necessary condition for monitoring and control of a Power System (PS) is possessing a credible model of this system. The PS model for a need of dispatchers in national control centre is created in real time. An important element of such a model is a topology model. PS Topology Verification (PSTV) is an important problem in PS engineering. Often this problem is solved together with PS state es...

in this article, thermo-elastic-behavior of a thick-walled cylinder made from a polystyrene nanocomposite reinforced with functionally graded (fg) single-walled carbon nanotubes (swcnts) was carried out in radial direction while subjected to a steady state thermal field. the swcnts were assumed aligned, straight with infinite length and a uniform layout. two types of variations in the volume fr...
