determination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولFocus on abnormal air: diagnostic ultrasonography for the acute abdomen.

متن کاملFree-breathing dynamic magnetic resonance imaging of the abdomen
Abdominal magnetic resonance imaging (MRI) is complicated by tissue motion as well as by weak tissue contrast. The major source of motion is respiration, which can be dealt with by breath-hold imaging or by respiratory triggering. Nevertheless, these commonly used methods are known to have their limitations in terms of patient burden as well as in image quality. We propose a method that allows ...
متن کاملRare cause of acute surgical abdomen with free intraperitoneal air: Spontaneous perforated pyometra. A report of 2 cases
BACKGROUND The acute abdomen accounts for up to 40% of all emergency surgical hospital admissions and a large proportion are secondary to gastrointestinal perforation. Studies have shown the superiority of the abdominal CT over upright chest radiographs in demonstrating free intraperitoneal air. Spontaneous perforated pyometra is a rare cause of the surgical acute abdomen with free intraperiton...
متن کاملOPEN MANAGEMENT OF THE SEPTIC ABDOMEN
Severe intraabdominal infection associated with abdominal wall, intraperitoneal and remote organ complications, still carries an unacceptably high morality rate. In addition to the fundamental principle of eradication of the source of infection, various treatment modalities have been suggested to improve the commonly grave outcome. Amongst these, open management (OM) of the septic abdomen,...
