The FDTD and the Haar-based MRTD algorithms are applied to the full-wave modeling of high-frequency structures that require the combination of differential equations with time-constants of different orders. The numerical coupling of Maxwell's and mechanical equations for the simulation of a MEMS capacitor and of Maxwell's and solid-state equations for a pn diode is discussed in detail.

Continued developments of sensor technology including hardware miniaturization and increased sensitivity have enabled the development of less intrusive methods to monitor physiological parameters during daily life. In this work, we present methods to recover cardiac and respiratory parameters using accelerometer and gyroscope sensors on the wrist. We demonstrate accurate measurements in a contr...

This paper presents the design, analysis, and real-time experimental evaluation results of a nonlinear sensor fault diagnosis scheme for quadrotor unmanned air vehicles (UAV). The objective is to detect, isolate, and estimate sensor bias faults in accelerometer and gyroscope measurements. Based on the quadrotor dynamics and sensor models under consideration, the effects of sensor faults are rep...

in this paper, an adaptive neuro fuzzy inference system (anfis) based control is proposed for the tracking of a micro-electro mechanical systems (mems) gyroscope sensor. the anfis is used to train parameters of the controller for tracking a desired trajectory. numerical simulations for a mems gyroscope are looked into to check the effectiveness of the anfis control scheme. it proves that the sy...

A novel structural design of a wave energy converter (WEC) is proposed, utilizing gyroscope as the main component for absorption. vacuum-sealed, high-speed flywheel implemented within to convert and reduce loss from air resistance. dynamic model that considers response floater, gyroscope, power take-off (PTO) system with multi-degree-of-freedom (DoF) excitations created. The primary parameters ...

In this research, the effect of two process control agent: methanol (liquid state) and stearicacid (solid state) on mechanical alloying process of Ti and Al with equal at%(Ti50Al50) wereinvestigated. Phase transformation at presence of two PCA was: at first, powder mixture wastransformed to a metastable solid solution of Al in Ti lattice (disordered hcp) and then transformed toamorphous phase w...
