In the paper a review is given of the current state of the art of micromachined inertial sensors accelerometers and gyroscopes. These sensors can be used in a wide range of applications and micromachined devices have a number of significant advantages over their conventional counterparts such as lower cost, smaller form factor and lower power consumption. An overview will be given over the dive...

2014 The capabilities of Rutherford backscattering in surface analysis are limited by the energy resolution of the solid state detectors and their rapid degradation for heavier projectiles. Here, we investigate the possibilities of an electrostatic analyser (ESA) detecting heavy projectiles (7Li+, 12C+) backscattered from various compound semiconductor surfaces, essentially with respect to mass...

Personal samplers or in general blunt body samplers are widely used in occupational hygiene for collecting air contaminants in the work environments. This work is part of an ongoing research into the performance evaluation of personal samplers, particularly in terms of their aerodynamic properties. Velocity profiles have been measured around and within typical cylindrical sampling devices, ...
