Marker-less motion analysis system is the future for sports motion study. This is because it can potentially be applied in real time competitive matches because no marking system is required. The purpose of this
Kx can be computed using Equation (2.23) because all the other terms in this equation can be measured in the field. The residence time T can then be calculated from the equation for turbulent diffusion scaling (Fischer et al., 1979): (2.24)T=L2Kx where L is the length of the tidal ...
Real-Time Kinematic (RTK Global Positioning System (GPS) in combination with Inertial Measurement Unit (IMU; measures the roll, pitch and yaw of the platform) improve the projection of the images onto georeferenced maps.

The distinguishing feature of a vertical ball screw feed system without counterweight is that the spindle system weight directly acts on the kinematic joints. Research into the dynamic characteristics under acceleration and deceleration is an important step in improving the structural performance of vertica...
In projectile motion, when is speed the greatest? A ball is thrown horizontally at a speed of 6.52 m/s off of a 10.11m tall cliff. How much time will it take to reach the bottom of the cliff? What is the velocity of the bob when the cord is vertical? What is the tension of ...
The effect of vertical ground motion on the axial force variation is evaluated by considering the ratio of the axial force variation induced by the only vertical excitation to gravity load as shown in the following equation: (2) where AFV is the axial force variation which is defined as the...
The vertical velocity equation must consider gravity. The precise value of the acceleration due to gravity is a very long decimal, but it is often rounded to 10m/s2. This means that for every second an object is in a vertical motion, its velocity changes by approximately 10 meters per ...
The source time function of the points sources is extracted from the onboard SP records that represent the three-component motions of the lander deck. To be more specific, we first obtained the motion of the lander feet from the motion of the deck by applying a kinematic matrix given by ...
If the kinematic viscosity decrease then the velocity of fluid increase. Fig. 4(a–b) illustrates the velocity and temperature distributions within the boundary layer for various values of driving parameter(β). It is found that with the increasing values of the driving parameterβ, the momentum...
By deriving equations based on Lagrange equation function and establishing relationships between kinetic energy and potential energy, we can obtain undamped equations of motion for the system. Subsequently, we can determine the undamped free vibration frequency fz of system. Firstly, let us calculate ...
