We prospectively compared, within the same center and during the same period of time, the perioperative parameters as well as the oncological and functional results of both open retropubic (ORP) and laparoscopic radical prostatectomy (LRP). From September 1999 to September 2001, 162 patients with prostate cancer were treated with radical prostatectomy, 77(More)
In this paper we present a new measurement solution for the characterization of high frequency devices under large signal operating conditions. It is shown how a device-under-test (DUT) is put under large signal operating conditions and how one then measures the voltage and current waveforms at the signal ports in order to completely and accurately(More)
OBJECTIVES The aim of this study was to evaluate the effectiveness of a new minimally invasive surgical procedure, the Trans-obturator Vaginal Tape (TOT) in the treatment of female urodynamic stress incontinence (USI) and to analyse functional results and quality of life after one year of follow up. MATERIAL AND METHOD 120 consecutive women with stress(More)
—A new pulsed-IV pulsed-RF measurement system using a large signal network analyzer (LSNA) is proposed to address the problem of desensitization afflicting conventional pulsed-RF measurement systems. Several extraction methods using the entire spectrum measured by the system are presented to extract non-desensitized pulsed-RF S-parameters of a transistor.(More)
To evaluate peri- and postoperative morbidity, and long-term oncologic and functional results of our laparoscopic radical cystectomy (LRC) technique, comparing it with our standard open approach. Between 2000 and 2010, 54 patients underwent LRC for urothelial cell carcinoma of the bladder in two academic hospitals. The procedures were performed by two(More)
A measurement and black-box modeling technique is described enabling the characterization of nonlinear microwave components under periodic large-signal excitation. First, the mathematical model is theoretically described. The model is based on the assumption that the superposition principle holds for the effect of all spectral components, except the(More)
—It is shown in this paper how the classical concept of the " network analyser " can be extended towards modulated and large-signal operating conditions. The concept is demonstrated by measuring the saturated behaviour of a MMIC amplifier, excited by modulated signals with CDMA characteristics. It is then illustrated how the measured data can be used to(More)
— Using a nonlinear black-box model based on the Volterra theory it is possible to describe the nonlinear behavior of a high frequency amplifier. Acquiring only a strongly reduced set of measurements it is easy to predict the load impedance curves anywhere on a Smith Chart. The classic load-pull approach involves the acquisition of a large amount of data(More)
—The modeling and balancing of IQ modulators and the development of linearization techniques for power amplifiers (PA) such as output baseband modulation (OBM) benefit from the availability of linear and nonlinear MIMO Volterra system parameters involving both baseband and RF signals. A triggered LSNA system is reported for this purpose. By synchronizing(More)
