Purpose Ossification of ligamentum flavum (OLF) is the leading cause of progressive thoracic myelopathy (TM) in East Asian countries. Surgical decompression is the general treatment for TM. This study investigated the application of percutaneous full endoscopic posterior decompression (PEPD) for the treatment of thoracic OLF. Methods Eighteen patients with TM were treated by PEPD under local anaesthesia...
A new solution to GNSS receiver baseband signal processing SoC platform based on OpenRISC CPU is presented. The system hardware structure of the SoC platform on Xilinx FPGA is built. The GNSS correlator which is implemented in Xilinx FPGA is presented. OpenRISC CPU and Wishbone are migrated and OpenRISC software functions are expounded. The proposed SoC platform is useful to design a low cost GNSS...
Three framed-ALOHA-based transmission control solutions and interval estimation method (IEM) are proposed for EPCglobal Class 1 Generation 2 ( EPC C1G2) RFID system. The presented transmission control solutions build on earlier work on dynamic framed-ALOHA protocol, but have been adapted to address characteristics of EPC C1G2 RFID system. The proposed IEM selects directly optimal frame size from a...
