A Fourier transform spectrometer (FTS) that incorporates a closed-loop controlled, electrothermally actuated microelectromechanical systems (MEMS) micromirror is proposed and experimentally verified. The scan range and the tilting angle of the mirror plate are the two critical parameters for MEMS-based FTS. In this work, the MEMS mirror with a footprint of 4.3 mm × 3.1 mm is based on a modified...

AIM Analysis of indications for stapes revision surgery in patients qualified for the secondary procedure at the Otosurgery Dept. Medical University of Lodz. MATERIAL AND METHODS 25 cases of stapes revision surgery out of the 385 total treated surgically otosclerosis cases are discussed. RESULTS In group A (patients after total stapedectomy) the following indications for the secondary surgi...

In a prospective study, 165 total stapedectomies and 152 small fenestra stapedotomies were performed by three experienced surgeons between 2001 and 2003. In total stapedectomy, a self-made Schuknecht steel wire connective tissue prosthesis, and in stapedotomy, a 0.6-mm platinum wire Teflon piston was used. The pre- and postoperative bone conduction thresholds were compared at the frequencies 25...

reactivity controlled compression ignition (rcci) is a novel combustion concept which uses port fuel injection (pfi) of a low reactivity fuel and direct injection (di) of a high reactivity fuel with optimum multiple injection to provide a stratified mixture inside the combustion chamber. piston bowl design has a considerable effect on engine’s pollutant emissions specially unburned hydrocarbons...

This paper studies the global feedback stabilization problem of a system with two pistons and area between them containing viscous compressible fluid (gas) modeled by Navier-Stokes equations. The control input is force applied on left piston (boundary input) overall consists nonlinear Partial Differential Equations four Ordinary Equations. Global stabilizers are designed for means Control Lyapu...

This paper presents the modeling and control of a prototype compact free liquid-piston engine compressor. The dynamic model includes 1) the injection dynamics of the air/fuel mixture, 2) the dynamics of heat release during combustion, 3) the inertial dynamics of the magnetically latched combustion valve, 4) the mass flow dynamics of the combustion and exhaust valves, 5) the inertial dynamics of...

OBJECTIVE To compare the hearing and otoacoustic emissions (OAE) outcome of stapedotomy employing 0.4 and 0.6 mm diameter prostheses. MATERIALS AND METHODS In total, 18 patients with otosclerosis participated in a prospective, double-armed, randomized cohort study. All the patients underwent small fenestra drill stapedotomy employing the Causse fluroplastic large loop piston prostheses. The p...
