Two-Dimensional Proportional Chamber Readout Using Digital Techniques

Numerical Simulation of Flash Boiling Effect in a 3-Dimensional Chamber Using CFD Techniques

 Flash Boiling atomization is one of the most effective means of generating a fine and narrow-dispersed spray. Unless its complexity its potential has not been fully realized. In This Paper, a three dimensional chamber has been modeled with a straight fuel injector. Effect of Flash Boiling has been investigated by computational fluid dynamics (CFD) techniques. A finite volume approach with the ...

Efficacy of Digital Anesthesia: Comparison of Two Techniques

BACKGROUND Digital nerve block is commonly performed by care providers in medical fields. This study compares the blocks in terms of effectiveness of anesthesia and pain. METHODS Patients were divided into two groups. First group underwent digital block whereas 2nd group had transmetacarpal digital block. The subcutaneous ring block was performed by two injections of 3 ml of 2% lignoca...

Sensitivity enhancement of grating interferometer based two-dimensional sensor arrays using two-wavelength readout.

Diffraction gratings integrated with microelectromechanical systems (MEMS) sensors offer displacement measurements with subnanometer sensitivity. However, the sensitivity of the interferometric readout may drop significantly based on the gap between the grating and the reference surface. A two-wavelength (2-λ) readout method was previously tested using a single MEMS sensor for illustrating incr...
