High performance, micro-g resolution, small size, low cost, low power accelerometers are needed in many applications such as inertial navigation, Unmanned Aerial Vehicles (UAVs), and GPS augmentation. Several sensing methods have been used, including piezoresistive/electric, resonant, tunneling, and capacitive techniques. Capacitive sensing has several advantages in terms of high sensitivity, stable DC-characteristics, low power dissipation, low temperature sensitivity, and low noise floor. This research work demonstrates full functionality of high- sensitivity, low-noise capacitive...

This research shows a methodology to address a long- standing question in traffic safety relating to the evaluation of safety risk and the benefits associated with safety interventions. Safety interventions are associated with selectivity bias problems. By proposing a joint model of heterogeneity and selection bias using a discrete- count approach via multiple scales, the methods in this research may provide guidance on incorporating bias from site selection into design contexts associated with high levels of unobserved heterogeneity. This in turn can provide focused guidance on the...

Endoscopic spine surgery is the essence of the minimally invasive surgery technique. It’s a gradually developing field of spine surgery. Nevertheless, many doctors still have difficulties in acquiring an endoscope by themselves. This is especially true for transforaminal approach endoscopy. The editors of the book are pioneers in endoscopy and have had many interesting experiences related to transforaminal endoscopy. Since each patient has a different anatomy and disc shape, there are numerous practical techniques suitable for it, but few are specifically able to describe it. The main...
