FOSSEE IIT Bombay May 20

🎉 Successfully conducted a webinar on #Scilab and #Xcos as part of the FOSSEE project, IIT Bombay.

Sessions like these help bridge the gap between academia, industry professionals, and accessible computational tools. It is encouraging to see growing interest in Free and Open Source Software for numerical computing and engineering applications.

The Scariest Literature?

I feel Signals and Systems isn't too scary if accompanied with #MATLAB, GNU #Octave, #Scilab, or similar. And if you have #ham radio experience, you can do VERY well in this class! This did give me a run for my money in undergrad though.

@das_g Mi uzas #LaTeX en #MagistraProgramo.

Mi lernis tre malmulte #MATLAB helpante studentojn. Sed sufiĉe por helpi amikinon kun ŝiaj hejmtaskoj ĉe #Scilab.

starting from the conservation of the energy
(1/2)*m*(L(a)*a')^2+ m*g*y=Cst (1)
by derivation I get the additional term with a delta function compared to the preceding differential equation,. Then replacing this delta function by exp(-x^2/2s^2)/sqrt(2*pi*s^2), for a small s, I get a more realistic simulation. The energy is (almost) conserved (except near a=0), I should try to solve the first order differential equation (1) perhaps I will get a better result ...

I try to simulate an asymmetric pendulum, which length L(alpha) is l for alpha>0 and l/2 for alpha<0. I though the situation can be described by the differential equation :
L(alpha)*alpha'' +g*sin(alpha)=0
but when I plot the total energy over the time
E= (1/2)*m*(L(alpha)*alpha')^2+m*g*y
it is not constant !?! So I probably loose some term in the equation ...
