Coupled Definition and 360 Threads

Could some one please help me understand the current flow in this circuit (electron flow theory)... specifically, how does the capacitor charge, and how do the two transistors open/close? So far this is what I think... The current leaves the negative terminal, splits up into both branches...

I am doing a project that is similar to the coupled pendulum (http://www.her.itesm.mx/academia/profesional/cursos/fisica_2000/FisicaII/PHYSENGL/cpendula.htm but with springs instead of pendulum. My problem is that I am required to give background theory and the address of sites I got it from...

Two p electrons are in the coupled angular momentum states |lml1l2>=|2,-2,11>. What is the joint probability of finding the two electrons with L1z and L2z? Here is my thinking, With m1 + m2 =-2, the expansion becomes |2,-2,11>= C0-2|1,0>1|1,-2>2 + C-20|1,-2>1|1,0>2 + C-1-1|1,-1>1|1,-1>2...

I am looking for a method to solve coupled first order PDEs in following form: \frac {\partial u1} {\partial x} = f(x,t,u1,u2) \frac {\partial u2} {\partial t} = g(x,t,u1,u2) Subject to prober BC and IC. and consider: u1=F(x,t) u2=G(x,t) I am looking for...

hi! i want to know how to deal with the nonlinear coupled dfifferential equations? can anybody help me in that regard? if some one can paste MATLAB links/programs to solve the equations, it will be highly appreciated. regards, chap

I have a system that consist of the first spring attached to a ceiling and a first mass is attached to this spring. Then a second spring is attached to this first mass. Finally I have another mass attached to the second spring. So all of it is just hanging down. (I hope this is a good enough...

We're doing some coupled motion stuff in my AP Physics class and this is my second year of physics because we didn't do it last year in honors and I'm getting a bit lost with this. Does anyone have any links or explanations to help me understand this a little better?

I need information on coupled mode theory, specifically with reference to cylindrical waveguides. The more info the better. I have some references, but they are quite scattered, I am yet to find a reference that really encapsulates the 'heart' of coupled mode theory. If anyone has a good...

I have the infamous triatomic molecule, with two m masses in the extremes and one 2m mass in the middle, joined by two k springs. I have worked all through the problem (found frequencies, normal modes, drawn configurations, initial conditions) with no hindrances, but I can't seem to get the last...

any good website suggested on coupled pendulum? I have to do an investigation and I'm going to investigate simple pendulum (which is easy) than physical pendulum (just some calculation of mass as stuff) and than finally come into coupled pendulum. And I don't actually know much on coupled...
