QFT Control of a Two-Link Rigid-Flexible Manipulator

This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...

Patient comfort during flexible and rigid cystourethroscopy

INTRODUCTION Cystourethroscopy (CS) is an endoscopic method used to visualize the urethra and the bladder. AIM In this study, we prospectively evaluated pain in men undergoing cyclic cystoscopic assessment with rigid and flexible instruments after transurethral resection of bladder tumor (TURB). MATERIAL AND METHODS One hundred and twenty male patients who were under surveillance after a TU...

Flexible and rigid ureteroscopy in outpatient surgery.

BACKGROUND Outpatient surgery is critical to improve health care costs. The aim of the study was to prospectively evaluate the results of outpatient treatment of upper tract urinary stones by rigid or flexible ureteroscopy in a routine care setting. METHODS A database was created at the creation of the outpatient surgery department. 87 patients underwent 100 ureteroscopic procedures for urina...

Flexible and Rigid Cystoscopy in Women

PURPOSE Previous studies have evaluated the tolerability of rigid versus flexible cystoscopy in men. Similar studies, however, have not been performed in women. We sought to determine whether office-based flexible cystoscopy was better tolerated than rigid cystoscopy in women. MATERIALS AND METHODS Following full IRB approval, women were prospectively randomized in a single-blind manner. Pati...
