I do have the time points for each of the values.

Sorry, it is not an ODE model. That was my initial idea, but I ended up with a Monte Carlo type simulation without a lattice. That's why I am not sure how to proceed. All I can really do with my current knowledge is run sample simulations using guessed parameters.

Thanks for your reply. That's what I was mainly asking about - how should I go about measuring the closeness of the data? I don't have ideas for that. Since I don't know what p1,p2,p3 might be I could set them to be uniform distributions between 0 and 0.1, since I expect them to be small.

Hello, I've got some data on an epidemic in various locations - the total number of agents and number killed by the infection after 1 year. -This gives gives me a distribution of percentages of the populations that have been killed by the infection. (but all the percentage values are relatively...

hi, I'm simulating a system of molecules (water) and in order to pass through a barrier they have to overcome an energy barrier of 4kT. What is the probability of a water molecule passing the barrier or perhaps what is the average energy of a water molecule in my system? I know it's 1/2 *kT...

Very funny, as a matter of fact I'm an undergraduate and my assignment is to write a review of Technicolour without going into the mathematics. This is very difficult for someone who has taken only one course in subatomic physics and doesn't know any quantum field theory. I thought that maybe...

I'm having trouble with the following: technicolour predicts new massless techniquarks. The technicolour force breaks the chiral symmetries of these quarks and goldstone bosons emerge. But goldstone bosons are massless? Goldstone bosons are eaten by W and Z and thus W and Z acquire mass...

I don't understand why technicolor interactions are unobservable at low energies due to the fact that they are strong and confining. I thought color confinement means that quarks cannot be separated but rather new quark-antiquark pairs form and result in Hadron jets. Isn't this a feature of...

Hi! I'm trying to implement an implicit scheme for the continuity equation. The scheme is the following: http://img28.imageshack.us/img28/3196/screenshot20111130at003.png With \rho being the density, \alpha is a weighing constant. d is a parameter that relates the grid spacing to the...

It has to be this scheme. It is stated in my assignment to implement it. The code I wrote works fine, because I'm solving a sound wave that arises in the middle of the grid and by the time the programme finishes, the resulting sound waves don't leave the grid. So I can naively put the...

I'm not sure if that's what i want... What I need is: Look at the numerical scheme used to compute the solution. knowing the "phi" spatial distribution at time=n, I calculate the "psi" spatial distribution at time=n+1/2. From that I can obtain the phi spatial distribution at time=n+1, But...

Hi! I'm implementing a scheme to solve the following equation \frac{\partial \psi}{\partial t}=-c_{s} \cdot \frac{\partial \phi}{\partial x} \frac{\partial \phi}{\partial t}=-c_{s} \cdot \frac{\partial \psi}{\partial x} c_{s} is just the isothermal velocity of sound. The equations are for a...

I readhttp://www.learner.org/courses/physics/unit/text.html?unit=6&secNum=6" article and started wondering: What is the real reason for classical behavior of liquids gases at room temp? I have always thought that it is because of the deBroigle wavelength relation. At room T particles have a...

Hi, I'm wondering what will happen to the wave function of a particle when we take its mass to infinity. Suppose the infinite particle is in an infinite potential well, how do we sketch the wave function?

Actually I figured it out, I had to change one more thing in the Makefile. Now everything runs fine!
