Optimization acceleration techniques such as momentum play a key role in state-of-the-art machine learning algorithms. Recently, generic vector sequence extrapolation techniques, regularized nonlinear (RNA) of Scieur et al. [22], were proposed and shown to accelerate fixed point iterations. In contrast RNA which computes coefficients by (approximately) setting the gradient objective function ze...
In this paper a novel optical pressure and acceleration sensor based on micro electro mechanical systems (MEOMS) has been designed. For this purpose an integrated Mach- Zander interferometer has been used in LiNbO3 diaphragm. In this sensor, the strain caused by applied pressure or acceleration leads to a change in refractive index of the wave guide in the diaphragm due to the photoelastic effe...
Background and objective: Experience with past earthquakes and numerical analysis confirms that the durability of strong earth motion, significantly can affect the amount of failure of civil engineering systems. However, if the durability is related to a parameter which describes the intensity of the earth's motion, such as maximum velocity or maximum acceleration or spectral acceleration, then...
Background and Objectives: city bus drivers, during driving, are always exposed to the whole body vibration. This can lead to central- neural, musculoskeletal, and blood circulation disorders and develop occupational diseases due to vibration. The objective of this descriptive- analytic study is to investigate Tehran bus drivers;apos exposure to the whole body vibration. Materials and Metho...
