Association Française de Normalisation (AFNOR, English: French Standardization Association) is the French national organization for standardization and its International Organization for Standardization member body.
The AFNOR Group develops its international standardization activities, information provision, certification and training through a network of key partners in France who are members of the association. They are:
ACTIA (Association of Technical Cooperation for the food industry)
ADEME (French Agency for Environment and Energy Management)
ADEPT (Association for the development of international trade in food products and techniques)
COFRAC (French Accreditation Committee)
CSTB (Scientific and Technical Center for Construction)
CTI (Center Network industrial technology)
INERIS (National Institute for Industrial Environment and Risks) emerged from CERCHAR (Study and research centre of the Charbonnages de France) and IRCHA (National research institute of applied chemistry)
LCIE (Laboratoire Central des Industries Électriques)
LNE (Laboratoire National Metrology and Testing)
UTAC (Union Technique de l'automobile, cycle and motorcycle)

Hi everyone,
I'm really new to MCNP here and I'm "playing" around trying to understand what is going on.
I'd like to plot my tallies (F2, F4 and F6). Is there any tool (e.g. python or matlab package) you recommend?
I know that the internal plot MCPLOT is available but I'm wondering how you...
Normalize function f(r) = Nexp{-alpha*r}
Where alpha is positive const and r is a vector
I was just wondering if the fact that we have a vector value in our equation changes anything about the solution
Hello all,
I have a Radial Distribution Function in which the y-axis ie., g(r) value goes up to 40. But the other atoms values for g(r) are, say within 5. So when i plot these two it is difficult to see the smaller graph.
So how do i normalize these value..??
I have attached an image.
Any...

Okay, so I've been set this homework to find the normalisation constant, N, for the radial wave function in the 2s state for hydrogen (my title was too long to fit that vital information in). thing is; I'm having a bloody hard time and in the process confusing myself with trying to take out all...
According to my textbook the nonlinear Schrödinger equation:
$$\frac{\partial A(z,T)}{\partial z} = -i \frac{\beta_2}{2} \frac{\partial^2A}{\partial T^2} + i \gamma |A|^2 A \ \ (1)$$
can be cast in the form
$$\frac{\partial U(z,\tau)}{\partial z} = -i \frac{sign \beta_2}{2} \frac{1}{L_D}...

Hey there,
I used Mathematica to find the (non-normalised) wave function of an electron in the vicinity of a Hydrogen nucleus, and converted the answer from one involving Whittaker functions to one involving generalised Laguerre polynomials. My result is shown below:
This agrees with the...
Hi all,
I am currently operating a piece of equipment that essentially collects particles and separates them based on their size. Essentially you have 8 stages, and each stage has a differing size of particles it collects. For example:

The Attempt at a Solution
So to normalise a wavefunction it has to equal 1 when squared.
A is the normalisation factor so we have:
A.x2e-x/2a0.x2e-x/2a0 = 1
∫ψ*ψdx = A2∫x4e-axdx = 1
Then I've...
