python Programming Glossary: particleRandomizing (x,y,z) coordinates within a box http://stackoverflow.com/questions/12700211/randomizing-x-y-z-coordinates-within-a-box new to python and in my current assignment it looked at particles in 3D. The first part of the question asked to create a program.. to create a program that put identical non overlapping particles in a cubic lattice. So my code below just iterates through.. but put them in a random fashion and limit the number of particles that I have. This is the code I had for the first part. import..
python ball physics simulation http://stackoverflow.com/questions/14137475/python-ball-physics-simulation tutorial that had a specific length and didn't allow the particles to come closer go further than that specified length. Also.. forces in the usual way and calculate the position of the particles using the rotation for simplicity about the center of the system.. force vector and the radius vector from the center to the particle that suffers the force So that F r sin angle F r is the torque..

Hello I have an image that contains the shadows of ice particles measured by a particle spectrometer. I want to be able to identify.. that contains the shadows of ice particles measured by a particle spectrometer. I want to be able to identify each object so that..
How to Calculate Centroid in python http://stackoverflow.com/questions/18714587/how-to-calculate-centroid-in-python goes through and a new centroid is calculated for each particle. You don't even need the loop at all if you import the data..
Numpy interconversion between multidimensional and linear indexing http://stackoverflow.com/questions/3257619/numpy-interconversion-between-multidimensional-and-linear-indexing To make my usage concrete I have a large collection of N particles each assigned 5 float values dimensions giving an Nx5 array... an appropriate choice of bin boundaries to assign each particle a bin in the 5 dimensional space. N 10 ndims 5 p numpy.random.normal.. index in a way that vectorizes the operation for all N particles I would appreciate your insight. python indexing numpy share..
python- construction of lattice which traps molecules - doesn't work right http://stackoverflow.com/questions/8038420/python-construction-of-lattice-which-traps-molecules-doesnt-work-right of trap molecules which will have concentration c. Put 1 particle in a random position on the lattice and let it perform a random.. a specific number of steps. The walk will stop when the particle falls on a trap.............................. ...Beware of boundary.. ...Beware of boundary conditions. When the particle reaches the borders of the lattice it shouldn ™t be allowed to..
