When discussing motion, velocity is a key concept to understand. Velocity refers to the speed of an object in a specific direction. To calculate the average velocity, one must take into account the ...

Speed-time graphs are very useful when describing the movement of an object. This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the area ...

Abstract: In this paper, we propose a data-driven model lever-aging a Limited Penetrable Weighted Visibility Graph (LPWVG) derived from the photoplethysmogram (PPG) waveform for Pulse Wave Velocity ...
