Analysis of Code Division Multiplexing Technique Using a 2 Gchip/s Parallel CCD Matched Filter for 16-Channel ECDM-PON 査読

In this paper, a novel charge coupled device matched filter (CCD-MF) for Electrical code division multiplexing (ECDM) decoder is proposed and experimentally demonstrated. Simulation results clarify the influence of low charge transfer efficiency (CTE) and the validity of a parallel CCD-MF we proposed. A 15-channel ECDM system using a 2 Gchip/s, 2-parallel CCD-MF is experimentally demonstrated.

Linear motors have many applications because of their unique characteristic which are different from rotary machines. In particular, Linear Induction Motors (LIMs) have a simple and strong structure, a flexible mechanism, and so on. The most popular application of LIMs is in transportation systems. It is important to investigate the dynamic characteristics of LIMs in order for them to be successfully applied in transportation systems. However, it is difficult to measure the dynamic characteristics of LIMs. Long enough span or large enough diameter of a cylindrical drum is necessary for the secondary side in the ordinary measurement system.In this paper, the use of a disc-shaped secondary side to measure the dynamic characteristics of LIMs are proposed. The rotating dynamic characteristics of disc-shaped LIMs are converted into linear motion.

Double-barrel Damus-Kaye-Stansel operation is better than end-to-side Damus-Kaye-Stansel operation for preserving the pulmonary valve function: the importance of preserving the shape of the pulmonary sinus. 査読国際誌

OBJECTIVE: The Damus-Kaye-Stansel operation sometimes results in deteriorating semilunar valve insufficiency. We verified the semilunar valve function after the Damus-Kaye-Stansel operation and compared the end-to-side Damus-Kaye-Stansel with the double-barrel Damus-Kaye-Stansel. METHODS: Forty-seven patients who underwent the Damus-Kaye-Stansel operation between June 1993 and August 2008 were retrospectively reviewed. Any patient who underwent a Norwood-type operation was excluded. The median age at operation was 19 months (range, 0-276 months). Forty-five patients were Fontan candidates. Thirty-nine patients underwent pulmonary artery banding before the Damus-Kaye-Stansel operation. Twenty-two patients had undergone an arch repair previously. The semilunar valve function was evaluated by echocardiography. RESULTS: Thirteen patients underwent the end-to-side Damus-Kaye-Stansel operation, and 34 patients underwent the double-barrel Damus-Kaye-Stansel operation. The mean follow-up period was 71 ± 50 months (range, 1-188 months). Although there were 4 deaths, no death was related to the Damus-Kaye-Stansel procedure. Two of the patients with early death could not undergo a postoperative evaluation of the semilunar valves. The semilunar valve regurgitation mildly deteriorated in 7 patients (pulmonary regurgitation in 5 patients and aortic regurgitation in 2 patients). Pulmonary regurgitation deteriorated from none to mild in 1 patient, none to trivial in 2 patients, and trivial to mild in 2 patients. Both deteriorations in aortic regurgitation ranged from none to trivial. Semilunar valve regurgitation did not affect patients' circulatory condition. The end-to-side Damus-Kaye-Stansel operation more frequently caused a deterioration in pulmonary regurgitation than the double-barrel Damus-Kaye-Stansel operation (4/11 vs 1/34, P = .001). No surgical intervention for a systemic ventricular outflow obstruction was observed in the follow-up period. CONCLUSIONS: The double-barrel Damus-Kaye-Stansel operation was found to be superior to the end-to-side Damus-Kaye-Stansel operation for the prevention of postoperative pulmonary regurgitation.
