can anybody tell me the expansion for the divergence of tensor vector product \nabla.(\tilde{K}.\vec{b}) for the case of scalar and vector the expansion is given by \nabla.(a\vec{b})=a\nabla.\vec{b}+\vec{b}.\nabla a

Hi everyone, I have couple questions about the no cloning theorm. It states that a quantum state can't be precisely copied. 1-Can you explain to me in very simple words why this theorm violat the uncertainty principle? 2-Also when I read the prove of the...

Sorry I just read the massage from the forum, I didn't thought that this is considered to be a homework question. Sorry all...

Yes my solution was not correct I knew, I am asking what is the mistake in my solution so that I can get benefit of my mistakes. Is there any wrong with that!

Hi all I tried to solve one of the magnetostatic problems and I end up with a trivial solution. The problem as shown in the figure, we have an infinite current carrying line and a circle with a radius "b" and current I2. The problem asks for the force being exerted by the line on the...

Wow really really amazing Unfortunately, there is something puzzling me which is:- How did you get the idea of substituting u=tan(x/2)

Hi all Can you solve the following integration: - Integration [ cos(x)/(c+cos(x)) ] by dx where c is a constant or that one: - Integration [ 1/(c+cos(x)) ] by dx if one is solved I will be able to make the other

I am not sure if I have full understanding of capacitors energy, because I found a contradiction in solving one problem. The problem is: - If an uncharged capacitor connected to another fully charged capacitor in parallel, what will be the new charge distribution on both capacitors...

Hi everybody... http://www3.0zz0.com/2008/07/02/08/264668819.jpg As shown in the previose figure, the output from the op amp is sequre root the input signal. Since the feedback of our circuit is sequare the feedback signal ( the output), we shall expect the output to be sequare root for...

Hi again I discover that not all of the data rate for RS-232 are providen by may PC. but still I have problem. The data that I want to load on may FPGA board is very larg and RS-232 have very low bit rates. May bord is spartan-3 digilent (X3S1000) Do you have any other way to load these data...

Hi I am using RS-232 connection to may FPGA, and I want to send information from matlap. Whan I set may VHDL program to the defult seting of the RS-232 which have 9600 bit/sec, then may FPGA show the data correctly. but whan I change the VHDL program and the matlap seting to anthor...

berkeman... No VHDL

Hi chroot.. My knowledge in this field is limited. I read about using JTAG but JTAG can be use to program the FPGA by loading .bin file (binary file) on it. so How can I use JTAG to load these data without effecting the FPGA. Thinks chroot for your respons

Hello everybody... I have spartan 3-1000 FPGA and I want to show some graphs to CRT monitor using VGA. I Know how to show the graphs from the SRAM and give them into the VGA. the question is How to load these data into the SRAM?? --can anyone help me

actully in the beginning I discover this from the complex analysis but look at this===> http://img90.imageshack.us/img90/2028/proof9zu.gif http://img90.imageshack.us/img90/2028/proof9zu.gif
