Position, Velocity, and Attitude Estimation Based on MARG and Position Measurements Under Unknown External Acceleration

Abstract: Estimation of position, velocity, and attitude of a rigid body is crucial for various applications. Many of these rely on position and Magnetic, Angular Rate, and Gravity (MARG) sensors, ...

Study on gas velocity distribution of gas-liquid stratified flow based on numerical simulation and PIV

The velocity is an important parameter for the fluid flow characteristics in the two-phase flow. In the gas-liquid two-phase stratified flow, the most easily obvious force equilibrium point is at the ...

Velocity-Adaptive Irregular Point Spread Function Deconvolution Imaging Using X-Shaped Denoising Diffusion Filtering

Abstract: Most least-squares migration (LSM) imaging methods use iterative gradient update methods to approximate the inverse of the Hessian matrix, but such approximations are not accurate and ...

A Crash Course on Derivatives

There you are in your introductory physics course. The course requirements say that you have to be in Calculus 101 (it's probably not called that) in order to enroll in Physics 101. Why? There are two ...

Impact of a systolic parameter, defined as the ratio of right brachial pre-ejection period to ejection time, on the relationship between brachial-ankle pulse wave velocity and ...

Increased pulse wave velocity (PWV), which reflects increased arterial stiffness, is reported to be an independent predictor of cardiovascular outcomes 1, 2 and is associated with the presence of ...
