Model: Transport of diluted species - time dependent I have solved the equivalent of Taylor dispersion in a rectangular channel as a function of time. In order to compare with Taylor's analytical expression, I need to determine the average concentration in the y direction as a function of x ...
How to calculate torsional stress-strain from torque and angle of twist data in a torsion experiment? Hooke's Law defines the stress-strain relationship for an elastic material: s=Ee, where E= . Calculate a numerical value for (i) the resilience and (ii) the toughness of a metal that ...
Eccentric Anomaly: a time dependent term in Kepler's equation which must be solved for in order to calculate a planet's position on its orbit. Eccentricity: A measure of how "elliptical" an eclipse is (measured from 0 to 1). For example, a circle has an eccentricity of zero, not ver...
I am performing a large eddy simulation of the swirling flows. Now I wish to calculate the turbulent kinetic energy (TKE) over a plane. Would it be correct to calculate the TKE by using the RMS values of the velocity components as: ...
In principle, it is possible to calculate the angular velocity by performing signal processing on the force signal. The signal processing algorithms were coded using MATLAB®. The basic approach was to take a vector of consecutive force samples and fit a sinusoid having the form given in Equati...
Calculate the acceleration of the car. The formula incorporating the position, x(t), at time t as a function of the initial position, x(0), the initial velocity, v(0), and the acceleration, a, is x(t) – x(0) = v(0)∙t + 1/2∙a∙t^2. Plug in x(t) – x(0) =...
Once the GPS has determined the position of an object, the system can calculate the physical distance between two objects as well as the time it will take to travel from one point to another. The GPS is government operated and is usually regarded as the “universal” form of navigation due...

The equation to calculate the BPFO is the following: Where Nb is the number of rolling elements, Bd is the Ball diameter, Pd is the Pitch diameter and β is the contact angle. Typical BPFO frequency is from 2-15 x RPM. Representation of outer race defects in the frequency domain ...
[23] Recently, it was proposed to calculate the changes in PPV during a tidal volume challenge that consisted of increasing the tidal volume transiently (from 6 mL/kg to 8 mL/kg) to overcome the limitation of PPV in cases of low tidal volume ventilation.[24] Excellent results have been ...
