Purpose Acetabular component position is important for stability and wear. Fluoroscopy can improve the accuracy of acetabular component placement in the posterior approach and the direct anterior approach (DAA). The purpose of this study was to determine if the direct anterior approach in the supine position facilitates the accurate use of fluoroscopy and improves acetabular component position. ...
Some considerations for interference suppression technologies in multi-band frequency hopping ultra-wideband communications are made. Based on this communication system, the novel coexisting interference detection algorithm is proposed in this paper. This new algorithm can be realized in low complexity and in comparatively low level sampling rate. With the estimation parameters provided by the new...
