In coping with the trend toward the much higher powered electric-motor driven injection molding machine, multi-AC servomotors control system has become necessary in order to control the molding machine mechanism. Thus, it is inevitable to use a synchronous positioning control technique not to cause the excessive mechanical stress in the machine body. It is possible to realize the synchronous po...

Background: While various radiographic parameters and application of manual/gravity stress have been proposed to elucidate instability for Weber B fibula fractures, the prognostic capability of these modalities remains unclear. Determination of anatomic positioning of the mortise is paramount. We propose a novel view, the Gravity Reduction View (GRV), which helps elucidate non-anatomic position...

We have measured cardiovascular changes associated with insufflation of carbon dioxide and the reverse Trendelenburg position during laparoscopic cholecystectomy, using transoesophageal echocardiography in 13 healthy patients. End-tidal carbon dioxide values increased after insufflation of carbon dioxide, with values significantly (P < 0.05) increased after lateral tilt positioning. Creation of...

Fluoroscopy is a widely used imaging technique during spine surgery. While most neurosurgeons act familiar with the x-ray-based image guidance, resident physicians need to learn how to obtain a meaningful image, which requires precise orientation to the unexposed spinal anatomy. We present a simulation system for training of fluoroscopic localization for spinal procedures. After positioning of ...

Arthroscopic shoulder surgery can be performed in both the beach chair and lateral decubitus positions. The lateral decubitus position allows for excellent exposure to all aspects of the glenohumeral joint and is therefore frequently employed in procedures such as stabilization, in which extensive visualization of the inferior and posterior aspects of the joint is required. Improved visualizati...

Airborne synthetic aperture radar (Airborne SAR) can accurately locate key targets and regions by using the flight parameters of aircraft relative position information between target which be obtained from airborne positioning orientation system (POS). In course flight, will deviate ideal path due to atmospheric turbulence, results in calculation deviating actual position. order improve accurac...

The accuracy of brackets placement is a key factor in successful orthodontic therapy. An in vitro study was conducted in ten models from a natural maxillary teeth model in order to compare the accuracy of brackets placement between two direct bonding instruments: the pole-like Bracket Positioning Gauge and the star-like Bracket Positioning Gauge. Our results have shown that: the star-like Brack...

By using a non-standard limited resource technique in wireless networks it is possible to reach features, which are more suitable for sensor networks and personal embedded applications than using standard protocols. Using new heavily integrated controller chips and RF-modems, it is possible to implement new features, for example, low-power routing, positioning and dynamic flat topology in limit...

The increased complexity and dynamism of present and future Multi-Agent Systems (MAS) enforce the need for considering both of their static (design-time) and the dynamic (run-time) aspects. A type of balance between the two aspects can definitely give better results related to system stability and adaptivity. MAS organization is the research area that is concerned with these issues and it is cu...
