Increasing demands in performance and quality make drive systems fundamental parts in the progressive automation of industrial process. The analysis and design of Mechatronics systems are often based on linear or linearized models which may not accurately represent the servo system characteristics when the system is subject to inputs of large amplitude. The impact of the nonlinearities of the d...

Fractures of the radial neck account for 5% 10% of traumatic lesions of the elbow in the child. Conservative method of reduction may fail to reduce severely displaced fractures. Open reduction of severely displaced radial neck fractures is associated with a high incidence of complications. The present study describes the results achieved after closed and indirect reduction of the severely displ...

We report 2 cases of axillary artery injury secondary to low-energy proximal humeral fractures. In case 1, early diagnosis based on signs of acute ischaemia of the arm enabled early treatment and a favourable outcome. In case 2, there were no signs of ischaemia or neurological deficit, resulting in delayed diagnosis and increased severity of the injury. The patient developed a false aneurysm an...

Artificial ground freezing (AGF) is used worldwide for vertical shaft sinking in difficult hydrogeological conditions. The modern tendency to determine the design parameters of technique based on numerical simulation. This work devoted simulation formation an ice-soil wall soil stratum due AGF and under protection wall. For this purpose, a fully coupled thermo-hydro-mechanical model has been de...

A methodology for estimating the force distribution that occurs along a needle shaft during insertion is described. An experimental system for measuring planar tissue phantom deformation during needle insertions has been developed and is presented. A two dimensional linear elastostatic material model, discretised using the Finite Element Method, is used to derive contact force information that ...

The stomatostylet of Criconemoides curvature consists of three parts: tooth cone, shaft, and knobs. The tooth cone constitutes the outer conical covering and inner lining of the anterior half of the stylet lumen. The tooth cone is easily separated from the shaft by treating an isolated styler with 0.5% sodium hypochlorite. The posterior half of the shaft is cylindrical, tapering anteriorly to f...

background femur fracture is one of the most common fractures in children. certain parameters such as the patient’s age, the exact location of fracture, type of fracture, the mechanism of fracture, and the accompanying injuries determine which one of the many treatment techniques be used in each case. objectives we aimed to compare the results of close and open techniques in pediatric femoral s...

vascular injuries with acute or chronic arterial hemorrhage after femoral shaft fractures are a rare but a life-threatening complication. we observed a case of iatrogenic rupture of the profunda femoris artery after the internal fixation of a femoral shaft fracture. the pseudoaneurysm, presenting with painful expansile swelling and hemodynamic instability, together with the rupture was evident ...

A method for measuring shaft diameters is presented using structured light vision measurement. After calibrating a model of the structured light measurement, a virtual plane is established perpendicular to the measured shaft axis and the image of the light stripe on the shaft is projected to the virtual plane. On the virtual plane, the center of the measured shaft is determined by fitting the p...
