When calculating the dV available from a rocket booster, the below calculation is used: (ISP . g) . ln(Mass when full/Mass when empty) Is 'g' always equal to 9.81 in this equation, or do you use the actual gravitational acceleration that the booster will experience, at it's given altitude, to...

Hi fellas! I am planning to start a ISP in our region, which uses cellular tower for bandwidth signal receiving & transmitting. We have established the leased line back bone to our network and figured out microwave & GSM antenna concepts to receive signals from suppliers and to send signals to...

I had an interesting idea for increasing the Specific Impulse and Thrust of a nuclear rocket engine; it's probably not practical - best case scenario 20% increase in exhaust velocity, with proportional increase in thrust, at the cost of 1.5x to 2x weight increase, and likely much lower - but I...

This morning, I called TDS to report an outage. The guy that I spoke to denied that there was any outage in my area and demanded that I unplug my modem, restart my PC, and auto-reconfigure the modem, among other things. After over 1/2 hour of that nonsense, he said that I would have to call...

My wife wanted a laptop, and she got a nice bonus this year, so I bought her an ASUS. After checking for compatibility issues, I also ordered a wireless DSL modem/router. I stayed with Actiontec because that's the brand my ISP provides. I tried to Auto-Config the modem with no luck, so I...

1. The launch vehicle takes the moon orbiter to a circular orbit around the Earth at 300km altitude. The orbiter is to perform a Hohmann transfer to a Lunar orbit, entering into a circular lunar orbit at 50km altitude. The objective of the mission is to put a 200kg orbiter around the Moon. The...

I'm trying to understand how ISPs agree to connect to each other by considering a hypothetical situation: Suppose I wanted to start my own ISP in a small town. Would I have to pay to connect to another network that is already connected to the internet (hence that would make me connected to the...

I would like to start blogging using WordPress. I've heard that my ISP needs to support PHP and MySQL in order for this to work? I have no idea what either is but I have seen a few examples of small test-files (info.php) I can upload to my site and attemp to view them in order to find out if my...

ISP can tell what my internal network ip's are? To make a long story short, I use a router, with two computers behind it, I called my ISP for technical help, and the technician there told me I use a router (which is a reason for him to not help me..). He said he sees more then one IP address...

Homework Statement Ok, so i have a bio ISP based on a genetic disease. The disease i am researching is called sarcosinemia also known as hypersarcosinemia, SARDH deficiency, SARD deficiency, and SAR (as far as i know but the list may go on). I basically need to give a 10 page report on how the...

A friend of mine is looking for a new ISP. He's looking into Verizon and I was wondering if anyone here uses Verizon (or know someone who does) and what your opinion of the service is. Thanks Pete

Hiya guys, I am thinking of becoming a small (for now) ISP here in my country (Indonesia), and I have some questions that I hope you guys can answer... Well, here goes: 1. Where can I get some general information on becoming an ISP? Like the steps to be taken, the skills/knowledge I need...

My country highiest broadband speed is only 2 Mb/s but I heard that some country has up to 100 Mb/s broadband speed . So, I wondered if I can become an isp with such speed but I don't know how ? Do I need to have a lot of ip ? What is the hardware/software requirement ? A nyone can give me...

Well after submitting a very long articulated email to my isp's support page, i got this in response: We limit FTP to 128kbps. Any file transfering program we limit the bandwidth because many of them are bandwidth intensive programs. The rate on it 128kbps. I claimed i needed...
