    Best programming language for an unguided evolutionary simulation

    I am most certainly, I however plan on making a way more sphisticated simulation and was wondering if you had any suggestions (that might make the programming of such a simulation easier).

    Best programming language for an unguided evolutionary simulation

    I one where to write a simulation based on evolutionary principles (reproduction, mutation, selection etc) that would consist of agents living in a 2d (grid) world, what programming language/environment would you suggest? I'm fimiliar with C but mostly with C# and java (and a lot of unrelevant...

    Nobody has any thoughts on the subject?

    > 1 Khz refresh rate screen

    To create a POV display I would like to get my hands on/create a screen that has a refresh rate of in the range of about 1khz to 100khz, the higher the better. LCD won’t go this fast but OLED seems to be (physically) capable. The chips that drive these oled screen can however not be used at...

    Nobody has any thoughts on driver chips?

    POV display using oleds

    I suppose that its possible to leave a blank (black) row in between the rows, giving each lit row some extra space until it need to be black. It would even be possible to just use one row, which would give the same effect as leds would, but with less spacing. The only problem I have is that most...

    POV display using oleds

    I'm wondering wheter or not its possible to create a POV display using oleds instead of seperate leds. My calculations show me that if I where to build a POV display using a 200 pixel radius, I would end up with 2 * pi * 200 = 1250 pixels in the perimeter. At 60 hertz this would mean 60 * 1250...

    Wire adapter instead of battery cells laptop

    I don't think that the charging circuit will pose any problem, since it worked fine using the battery and since the adapter input of the laptop is actually fully removed now, there is no possibility of the laptop trying to charge the battery since there is no other source to get its energy from...

    Wire adapter instead of battery cells laptop

    Thanks for the reply, The only reason I plan to install the resistor network is to get the right itermediate voltages (since the board inside the battery actually measures them). So I was planning on just using some large/high resistors, that will draw very little current. So that should be no...

    Wire adapter instead of battery cells laptop

    In short, I have a laptop with a broken internal power supply/regulation (it shorts out). So the adapter is still good. It also works when operating on the battery. What I would like to do is connect the adapter instead of the cells in the battery. Since laptop batteries are more than just a...

    op amp problem, the book gives a different answer

    I'm trying to solve a question about an op amp ciruit, but my answer differs from the given answer. I did this: because the output of the two left most op amps are directly connected to their respective inputs the output of the op amp is the same as the input on their positive terminals...

    Practice problem

    I don't do this for a course (just in my free time), so if you could just point out where my fault lies that would be very helpfull.

    Practice problem

    Just one more question, this time I do need to use Thenevin equivalence: I figured that I was dealing with a supermesh, since loop one and two share the 1.5Ix current supply. Using mesh analysis I got this for the supermesh: -6 + 5 * Ia + 7 * Ib – 4 *Ic = 0 And for node 1 I got this: Ia +...

    Practice problem

    Thats another practice problem erikl, my last questions are about a different one. The exact question that came with practice problem 3.13 is: "The transistor circuit in fig. 3.45 has B = 80, Vbe = 0.7V. Find Vo and Io." And the exact answer is: "Answer: 12 V, 600 uA I did not use Thevenin
