In this article the optical time division multiplexing technique for high speed point-to-point optical networks is discussed. We performed test of influence of selected types modulation formats in the optical time division multiplexing simulation model with a distance of 30 km. Additionally, this paper focuses on maximum bandwidth usage, improvement of bit error rate and the another goal is to ...

Patient motion compensation is challenging for dynamic 2D/3-D overlay in interventional procedures. A first motion compensation approach based on depth-layers has been recently proposed, where 3-D motion can be estimated by tracking feature points on 2-D X-ray images. However, the sparse depth estimation introduces a systematic error. In this paper, we present a theoretical analysis on the syst...

--Timebase distortions cause nonlinear distortions of the sampled waveforms by equivalent-time sampling instruments. A new model of quantizer is proposed to be used when a large part of timebase distortions is the result of non-random quantization error that is known. A compensation method based on this model is applied to timebase quantization. The simulated results show that the proposed comp...

OBJECTIVE To describe causes of substandard care in obstetric compensation claims. DESIGN AND SETTING A nationwide descriptive study in Norway. POPULATION All obstetric patients who believed themselves inflicted with injuries by the Health Service and applying for compensation. METHODS Data were collected from 871 claims to The Norwegian System of Compensation to Patients during 1994-2008...
