A major limitation of thermal therapies is the lack of detailed thermal information needed to monitor the therapy. Temperatures are routinely measured invasively with thermocouples, but only sparse measurements can be made. Ultrasound tomography is an attr ...
Purpose: Computer-assisted surgery has been established in orthopedic and neurosurgery, and is now becoming available as support for soft tissue surgery. Such technology should bridge the gap between pre-operative imaging and the intra-operative scenario b ...
Piezoelectric motors are particular motors converting electrical energy into mechanical movement, based on the inverse piezoelectric effect. Piezoelectric material, when electrical field applied, produces acoustic or ultrasonic vibrations. These vibrations ...
Velocimetry is used in various fields of research. In hydraulics, Ultrasonic Velocimetry based on the Doppler Shift effect can accurately resolve the quasi-instantaneous flow field [Takeda Y. Velocity profile measurement by Ultrasonic Doppler method. Exper ...
We investigate the effects of different silence modelling strategies in Weighted Finite-State Transducers for Automatic Speech Recognition. We show that the choice of silence models, and the way they are included in the transducer, can have a significant e ...
The invention relates to a method for preparing enantiomerically pure 4-pyrrolidinophenylbenzyl ether derivatives of formula I: wherein R, R, R, R, Rand n are as defined in the description and claims and to intermediates useful in the m ...
Just about every other technical publication you pick up these days makes sweeping statements concerning the pressures on scientists, engineers, and industries as a whole to get to market in less time, with an improved, less expensive product. I am reminde ...
The aim of this project is to study the LEM current transducer LAX 100-NP and to determine its dynamic performance using the finite element software Flux2D/3D. Firstly, the secondary impedance of the transducer is simulated, and the results are compared to ...
Ultrasonic machining is performed using closed-loop Z-axis position and force control. Micromachining requires tools smaller than 100 micrometers in diameter, necessitating the use of forces in the low mN range. ...
