  • Am I able to integrate this equation?

    I've tried integrating this equation in a few other programs and none of them seem to integrate this equation between 1 and 0:

    sin(t).e^(-0.1t^2) -- (between 1 and 0)

    Can any one tell me if it is possible to integrate this?

  • Corrupt Minecraft World! Help!?

    Hi, I've been working for about 30 hours now on a large building in Minecraft until yesterday when the save wasn't showing up in my list of worlds on MC. I thought I'd deleted it by accident - until I discovered the world was still in my saves file. It would appear it is corrupted, and I have no backup for it whatsoever - I tried restoring the files to an older version, but there were no past files to resort to - and I've tried a few other things which have all failed.

    I tried using Minecraft Region Fixer in the end. According to Region Fixer, there are no chunk and region problems - only the level.dat and player files are corrupted.

    It's great that I know they're the problem now... but I don't know how to fix them. I've tried making another superflat creative world and copying/pasting the region files into the new world, except I still cant find the building I was working on (I don't spawn anywhere near it anymore, and I probably will never find it by searching the whole map - assuming it's even there). So I don't know what to do. Can anybody help fix the broken files? Perhaps I could send someone the world to look at and fix it? I'm quite desperate to get this sorted. I don't have the ability myself... I just really want this corrupted world working. :(

    I'm open to any suggestions, and I will send the save files to anyone who thinks they could fix it by whatever way you want.

    Thanks.

  • Knight Rider PLC program HELP!?

    Hi, I've recently just started training in using PLCs and Mitsubishi GX Developer. I've been tasked with writing a program which will produce the knight rider effect (LEDs turning on and off, one side of the row of LEDs to the other) on a set of 6 LEDs (from y0 to y7) using GX Developer.

    Like this: http://www.youtube.com/watch?v=pqFdxnbpmw4

    Except the light goes from y0 to y7, and then back to y0 like in knight rider.

    However, I'm struggling.

    I really don't understand how to complete this task - I can get the LEDs to turn on one by one - but to turn off? I'm struggling. I was wondering if anyone out there could help me, possibly write the program, or just an example part to help - anything at all. Maybe somewhere to go to for something like this. Really need some answers guys. :(

  • Bought an item on Ebay (from US to UK) and the wrong item came?

    On the 16th of November I ordered a Tommy Gear hat (as part of my fancy dress outfit). I bough it on Ebay here:

    http://www.ebay.co.uk/itm/160826944595?ssPageName=...

    I'm in the UK and ordered it from the US, so obviously it took a long time to come - about 10 days at least. I was happy when it finally arrived until I opened the box and discovered the item I ordered wasn't inside at all - instead there's a toy car, in a blue box, called a "1935 Timmy Racer". On the invoice it says that it is the Tommy Gear hat, and there was also a note on the inside of the package saying that Ebay had checked and re-sealed the package.

    I honestly don't know what to do. I intend on contacting the Ebay user about this soon, but I just don't know what's happened. What do you think? Need some guidance guys - really annoyed.

  • Exponential Decay Question Help?

    "The police discover a murder victim at 7:30a.m. The body temperature of the victim is measured then and found to be 29 degrees C. A doctor arrives on the scene of the crime 30 minutes later and measures the body temperature again. It is found to be 24 degrees C. The temperature of the room remains constant at 16 degrees C. The doctor, knowing that normal body temperature is 37 degrees C, is able to estimate the time of death of the victim. If the cooling process is modelled by the equation

    Ɵ=Ɵ(zero)e^-kt

    Where Ɵ is the excess temperature over room temperature, use this model to estimate the time of death."

    (By Ɵ(zero) I mean the Ɵ with the small zero next to it, which I assume means the initial temperature).

  • Anyone have any ideas as to what these symptoms are a result of?

    I have a couple of problems which only appeared 2 days ago, and are baffling me.

    First of all, and the most notable of which, is a pain I have on the right side of my abdomen. It only came about yesterday night and has continued for about 19 hours. It's not noticeable until I move - especially to the right (which causes more pressure on that area). The pain is dull, like I've pulled something - and is only mild.

    Another problem is slightly on and off and originated 2 days ago. It is a pain towards the front of my abdomen which is also dull and not quite around the area where my stomach is. It's less painful than the pain on the right but is still noticeable. It may become worse after eating, although I'm not sure of this.

    Another problem which confuses me is my chest has been having problems, these being a cough, small amounts of yellow phlegm produced and a small rattle to my breathing. Last night it was worse, but it seems to be relatively okay now. Still apparent, but okay. When I breathe out the breath feels like it lingers for a little longer than it should and makes a small, squeaky sound. It isn't causing pain or much discomfort yet.

    Smaller symptoms include more mucus being produced at the back of my nose/mouth, slightly warmer than usual (especially around the pain in the right of my abdomen). My stools appear normal - if anything though much smoother than usual and sometimes with a little mucus.

    At the moment I'm taking acne tablets containing the antibiotic "Lymecycline". I have taken these for about 17 days now, one tablet a day. No problems up until now, despite the list of many possible side effects from taking them - which includes inflammation of the small intestine. The drug has been working - slowly, but making a difference.

    9 days ago I also cleaned a room full of dust - and I breathed in a lot of the crap that got into the air. This may explain my chest, as I can't see the drugs causing the lung problems.

    One last thing. I have been eating much less than I usually do too. In fact some days hardly anything - which could be a side effect from Lymecycline. I just haven't felt hungry ever since, and much rather take in fluids instead of eating. Nothing -too- drastic, but worth knowing.

    If anyone has any ideas, please tell me. Thought I would inquire before anything becomes serious, or if there's anything to actually worry about at all.

  • Rocket launch success and failure rates for different countries (or space agencies)?

    Hi, I've been reading about the recent failed launch of the Russian rocket. I am curious to know the success and failure rates of rocket launches for the countries (or space agencies) which launch a significant amount of rockets. I know Russia launches the most rockets - and still has the highest success rate of any other country for rocket launches (at around 93% I think?).

    If anyone could give some details regarding actual figures/statistics, that would be great - especially regarding Russian launches. Thank you. :)
