$45.00 Closed, closed Computer Science General CS Frame extraction from a video file with Java
Okay, I asked this before and didn't get an answer, so let's try again. This time with a higher bounty and a couple more details. I need a program (or code sample) that will: Extract a RANDOM (or... 		Apr. 08, 2008
$25.00 Closed, closed Computer Science General CS Java - extracting a frame from a video file
Basically, I need to extract a single frame from a multitude of video files of differing codecs. It doesn't really matter WHICH frame it is, but it needs to be able to be done quickly and (ideally)... 		Mar. 19, 2008
$4.50 Closed, closed Physics Electricity and Magnetism Another electrodynamics question
I also need help on this one. Please show as much work as possible! A sphere of radius R carries a uniform polarization P and a uniform magnetization M (not necessarily in exactly the same direction).... 		Feb. 20, 2007
$3.50 Closed, closed Physics Electricity and Magnetism Electrodynamics question
Find the self-inductance per unit length of an infinitely long solenoid of radius R carrying n turns per unit length. Show work. 		Feb. 10, 2007
$3.25 Closed, closed Physics General Physics Physics GRE question - cerenkov radiation
This is from my Physics GRE study group. It's related to nuclear physics and relativity. Can anyone help me with this? I just can't get it to work out. Cerenkov radiation is observed fro a beam of... 		Jun. 03, 2006
$2.50 Closed, closed Physics General Physics Physics question from thermodynamics and springs
This is another problem from my Physics GRE study guide. I can't remember how to link thermodynamics to spring oscillations. Consider a one dimensional anharmonic oscillator of energy E = p^2 / (2m +... 		Jun. 03, 2006
$0.50 Closed, closed Physics General Physics Electricity and magnetism physics question
This is from my intro E&M class. And, again, it's covered in my GRE study class and I can't remember how to solve it. Can anyone help me and provide work? Thanks! Find the magnetic field of a... 		Jun. 03, 2006
$1.00 Closed, closed Physics General Physics Circular motion and forces
This is from my Intro Physics class and it's being covered on the Physics GRE. I've forgotten how to solve this type of equation: Calculate the centripetal force required to keep a 4kg mass moving in... 		Jun. 03, 2006
$1.00 Closed, closed Physics General Physics Potential energy of gravitation field
I'm studying for the Physics AP test and there's a problem I cannot figure out. Can anyone help me with it? It's regarding the potential energy of a graviational field. I'm sure the answer is really... 		Jun. 03, 2006
$1.75 Closed, closed Computer Science Computer Graphics Explain DUDV maps to me
I've read some explanations on how fast refraction and reflection is accomplished in graphics programming, but I'm a bit fuzzy on the conceptual basis of dudv maps. I mean, I understand taking the... 		Apr. 27, 2006
