If a channel is 5Khz for a full duplex system in cellular systems does that mean person A and person B are using the whole 5Khz to communicate? Or can the channel accommodate a lot of people?

http://www.nytimes.com/2010/09/02/us/02discovery.html Apparently he thinks that if you threaten them, Discovery Channel can single-handedly solve all the world's problems.

I just want to tell everyone that Discovery channel host a show about "Universe and Stephen Hawkins" Really worth watching. It is a mind blowing series of episodes. Do not miss it. Really worthy Things like history of universe, Meaning for its existence , Dark matter, Black holes etc...

I need to replace an air conditioner compressor unit that sits on the 2nd floor walk way on my stilt home in the Florida Keys. The walk way is 24" deep and the original AC unit fit that dimension, however, the new unit is 31" square. When I install the new unit I would like to leave a 18" space...

(This was first posted to a newsgroup but there were no replies; so I am trying to post it here). I understand quantum teleportation works on qubits, but i can also work on regular bits. Suppose Alice has a message bit S. S is repeatable, because it is a regular bit. Now Alice wants to...

Hi folks, I'm wanting to buy a PS3 but have nowhere to plug in my audio except through a 5.1 system that's already being used by my PC. So, I decided to make a little box to wire up the two together and switch between them. But I'm having trouble with the switch... here's a nice picture in...

I remember when The Learning Channel started and was about knowledge, that was a LONG time ago. There has not been an educational program on there in more years than I can remember. Now they are hosting the Miss America pageant. Their programming is nothing but garbage, programs like The...

"Sci-Fi Science" on the Science Channel We stumbled across what appears to be a new series on the Science Channel a couple nights ago. Sci-Fi Science, as it's named, is hosted by Dr. Michio Kaku and has only run a few episodes. I was wondering if anyone has seen it. Here is a link to a few...

I love these shows. I know turbo doesn't have cable, so doesn't get them, so thought he might like the free video online. http://www.history.com/video.do?name=LockNLoad Tell me this Warriors guy doesn't make you think of Russ_Watters. http://www.history.com/video.do?name=warriors...

Dear all, I am trying to solve a simple model with Comsol to find the pressure drop in a rectangular channel W=5mm, h=0.6mm, L=10mm. When i try to set the inlet velocity to 0.5m/s the solver shows the error message "Maximum number of Newton iterations reached". The solver works fine if i set...

First I don't understand why this show is on the Travel Channel. Some stupid guy that locks himself into supposedly haunted buildings overnight and films himself screaming and pretending to see stuff. For halloween they are doing a "live" broadcast where "viewers" can posts their comments and...

History Channel' Universe Series -- What went wrong? I loved watching History Channels Universe Series but as of late it appears to be on the level of a moron. Why they dumb it down to this extreme? I'm insulted and stopped watching it. Can you guys help me complain send them email so they...

Last week I found wolfram alpha by random chance and it blew my mind, a couple days later I ran across this channel on youtube, and I can't stop watching their videos. I'm officially saying it's the greatest youtube channel ever. You will love it, trust me...

HI! I have a question about microfluidic devices. When you enlarge a channel, for example from 100µm to 2mm, is there a big variation of flow rate or back pressure? I can't find the equation to solve this issue. Thank you damien

Hi All, A potassium channel is designed to filter out potassium ions at a maximum rate of 100,000,000 ions s-1 A common concentration (cell's interior) of potassium is 100 mM and 5 mM outside. This means there is 553 water molecules for 1 potassium ion inside (55.3/0.100) and 11,060 water...

I am deisigning a pin jointed machine that uses some standard channel section. I am having difficulty getting consisitency with the channel section (type BS10279:2000 Hot Rolled Steel Channels) dimensions due to the wide nominal tolerances. Is anyone aware of any channel/U -Section that has...

History Channel...Arrrggghhh! The History Channel is playing this documentary called, "Earth's Black Hole." During the course of the documentary they ask whether a black hole under the ocean could be responsible for the bermuda triangle... Does anyone edit these things anymore?

Hey guys I've done my transmitter. it works fine. But, I need to know how to feed it with input from a generator within taking into account that such a transmitter has two channels R+L. shall i use two different generators to feed every single channel ? I really need some help.

I am trying to compare the fluid velocity given by the closed form solution and FEA analysis for fluid flowing through a channel that is 800u long and 100u wide. I am using the equation vmax= (gradP)*(radius)^2/(4*viscosity) I got 8.4cm/s in the former compared to ~10cm/s in the latter...

Hi, I am not sure how to count the channel capacity. If a symbol represents 10 bits of information, and a channel can transmit 10 symbols per second, what is the capacity of the channel in bits per second? C = 1 - H[x] How to go from there? Thanks!

A rectangular concrete-lined channel is 2m wide with Manning's n 0.012 and a bed slope of 0.0025 m/m. Obtain the depth of flow when the discharge is 9m^3/s. Q=V.A I have the discharge but how do I calculate the velocity without the area ?? Once I have the velocity I should be able to work it...

A trapezoidal channel with side batters 1:1 and Manning's n value of 0.025 has a bed slope of 0.0045 m/m. When the depth is equal to the bottom width the discharge is 7.5 m^3/s. Calculate the bottom width to the nearest 0.01m. Using mannings equation V= 1/n.R^2/3.S^1/2 S=0.0045 n=0.025...

Do any of you get this channel? Have you seen the show "Get Out"? It's a travel show where these three girls travel around the world and tell you about it. Oh, and they only wear bikini tops and they only go to tropical areas. I can't get enough of this show. It is so sexist, because these girls...

What do you think about creating a commercial free channel which plays nothing but pro musicians and teachers giving video lessons. You could have a channel for each instrument if you wanted. Maybe have one program that covers like 4 or 5 instruments: drums, bass, guitar, piano, voice. Then...

This show premiers tonight at 10 PM. I expect it to be a bunch of hype, but we will see. http://www.scifi.com/ufohunters/ I think it is the first regular series to address the subject of UFOs exclusively.

My friend recently reccomended i watch some footage of JZ knight, who claims to be channeling a spirit called Ramtha. Of course, i dismissed his comments, as i do not believe in spirits, or ghosts, or any other (probably psychosematic) phenomeneon. However, out of pure curiosity i did watch some...

History channel: "Alien engineering" show I'm curious if anyone saw this show, or part of it. (I only watched part, it was rather long). For a rather ga-ga premise, the show seemed to be fairly serious. A friend of mine commented that it might attract kids to science. I know I don't want...

Hutchison on the History Channel? WHAT THE HELL?!?!??!??!? You guys have probably heard of http://en.wikipedia.org/wiki/John_Hutchison" , the crackpot responsible for the hutchison effect. Today I was watching the History Channel, and there was some show about black holes and the possibility...

I have to find the maximun bps that it can be reach using a point-to-point link of 40 km long of optic fiber. I use an ITU normalized channel (100 GHz optic BW). So, I can choose any electric modulation and any optic modulation, too. Anybody could help me? Any answer is welcome. Thanks.

Hi to our nice community. I want to learn why in a binary symetric channel the channel is calculated as C=1+plogp+(1-p)log(1-p) I only know that the channel is denoted as C=maxI(X;Y) btw what ; means in X;Y? Unfortunately my book doesn't mention these things so if u can reply me or...

hi all - its been very long - hope everyone is well! just a data comms related question: When modelling a communication channel we normally include AWGN, that is, Additive white gaussian noise. Can anybody tell me why we use white noise in the model. I know it has a constant power...

I'm working on a fluid flow problem that doesn't seem very complex but the solution is eluding me at the moment. Given a length of smooth tubing of known ID and roughness with water running through it, is it possible to predict at what velocity the flow will transition from "pipe" flow (fully...
