Background The morbidity of knee arthritis is increasing among aged people and total knee arthroplasty has been its mainstream treatment to date. Postoperative rehabilitation is an important part of the procedure. However, the intense pain during the functional exercise involved has always been a challenge for both patients and health care professionals. The aim of this study is to test the analgesic...
In order to solve the low key distribution efficiency problem of the BB84 protocol, an improved BB84 quantum key distribution scheme is presented in this paper. Firstly the same polarization basis is used by the sender and the receiver with the consistent agreement. This process could make quantum key distribution rate higher. Then signature combined with the error correction method based on the odd...
In this paper, we bring forward a new approach for SAR imaging using fractional Fourier transform (FRFT). For synthetic aperture radar (SAR), the echo from the ground can be regarded approximately as a chirp signal, and the FRFT is a powerful way to concentrate the energy of a chirp signal. A two stepSAR imaging algorithms is suggested, and experimental results show that the efficiency and accuracy...
