An input and output states based responding ship motion nonlinear mathematical model is presented. Compared with state space model, the responding ship model costs less computation and preserves the ...

Ettringite is a hexacalcium aluminate trisulfate hydrate mineral that forms during Portland cement hydration. Its presence plays an important role in controlling the setting rate of the highly ...

A novel memory-based motion simulation (MBMS) model was developed as a general framework for simulating natural human motions for computer-aided ergonomic design. The MBMS model utilizes real human ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become ...

Abstract We report the early events of a twinned HMX crystal, as well as a perfect one for a comparison purpose, shocked with various velocities in the range of 6–10 km/s for 50 ps by molecular ...
