Hi I am trying to verify my manual solution for this problem by any way, so I tried NDSolve, and DSolve, in mathematica with no success. I don't need it in mathematica I just need any way poosible, even matlab, or any other numeric way/soltuion. Can some one help, or even give me the final...

Hi So the problem I have is I want to get the equation of motion of a vibrating beam under a nonlinear "Point" force. The equation would be like this for a distributed load (Which is not the case) But I want the load to be at a point at x=L So I have to options. Add an impulse dirac function...

OK there it is. I am measuring an optical beam's intensity vs the transverse dimension x which is a well known Gaussian pattern [y(x)]. My measurement technique. however, handles a unique situation after the beam has undergone some special spatial transformations. Ideally speaking, the net...

Thanks that looks like its worth a shot I will let you know when I try it :D

Yes you are right :) I want to know y(x). I thought you meant what I expected it to be. The thing about g(x) is that its a measured array of points that looks Gaussian but could be "not exactly". One cannot depend on visual inspection to call out the type of a function. Fitting it with a...

The y(x) is Gaussian as i pointed out and the measured g(x)looks Gaussian on the osciliscope by visual inspection but I don't know for sure Can the methods you did at the end of your post apply for y(x)=E*exp(x^2/a^2) ? If so what would it be ?

Deterministic

Its a physical quantity of a Gaussian nature (optical intensity = E*exp(x^2/a^2)) where a is a constant However due to the nature of the experiment we are trying to PROVE that its Gaussian to test our equipment If it is Gaussian we want to measure the constant a

Yes I got it thanks. I still can't solve it though, can you help :) :)

I am not following you on the not zero part but its a Measured signal (from lab experiment) and I think it should be Gaussian so I think it has zeros on its extremes What do I do?

Yes Ok that makes sense , So how do i get y(x)? Note that I am expecting it to be of a Gaussian nature but I can't know for sure

No I meant x as it is , a variable Its like convoluting with a rectangular function (I think ) And h is a constant btw

Hi I am facing a mathematical problem in my research. I am not a maths magor and i need to do this to move on with my research. Please check the picture for the equation http://i.stack.imgur.com/jQroR.jpg Mod note: Image was too large, so deleted it, and replaced it with LaTeX. Left the...

So for micrometer level dimensions , running at the KHz speed : The only issue I will see is a "series" resistance with the silicon part that is about 0.5 ohms ( Aluminum has resistivity 28.2 nΩ·m, while silicon 1KΩ·m) more than that of the aluminum part which will mean each part will behave as...

But isn't aluminum a "better conductor" ? isnt having a higher conductivity something that will upset the electric field distribution, since more charges will accumulate on the metal than on the silicon ?
