So I need to know how does comsol calculate element stiffness matrice and assemble them, and then programming it in livelink for matlab. I didn't find methods in COMSOL Multiphysics Reference Manual. Could anybody tell me or any suggestions? To be more specific, let's say, the second-...
where G is the elastic modulus, R the column radius, ρ is density, g the gravitational acceleration and J≈ 1.8663 is the smallest positive root of the Bessel function of the first kind of order −1/311. A similar expression is used in civil engineering to calculate the stability of bu...
Aim for moderate-intensity cardio, around 65% to 75% of your target heart rate to maximize fat burning. How to Calculate Your Target Heart Rate: Subtract your age from 220 to get your maximum heart rate. Multiply that number by 0.65 to find the lower end of your target heart rate. ...
As the force is applied to the sensor, its electrical output signal can be measured, converted, and standardized. The input force can vary between load, weight, tension, compression, or pressure, and it can only be measured by a sensor that is designed to calculate that type of force. (...
! task of the method is to calculate this force, and then use it to modify the position ! and velocity of grains. ! In lines 2-4, the initial conditions are set. It is necessary to set the number ! N of grains participating in the simula...
You should do this with Quaternions, it is much, much easier to interpolate with them than with EulerAngles. You can calculate a quaternion from the TxTransformation. In newer .NET version you will find classes in the System.Numerics namespace. Selected as BestLikeLikedUnlike ...
the ones in column IV are of great interest due to their position between the columns of B and As in the periodic table. In particular, the high p-dopability of BAs has been recently studied11,12. Photoluminescence and electron paramagnetic resonance experiments have been used11along with ab...
In section 1, we have already discussed the necessity of BP measurement and a brief of advanced technologies towards wearable devices. Section 2 and its subsections discuss the techniques and their algorithms used to calculate BP. The history of the validation protocol and the current standard for...
