Most independent vector can be an outliers. yes the vectors I am talking about are the rows of A matrix. I also know vector X and Y. I know the correct solution to the problem. I could have found X with a minimal definition of A since I have A over-defined, I want to find out how much...

Hi, I have a over constrained least squares problem. I also have the correct solution to the problem. Now I need to determine which of the vectors are contributing how much information that is close to the correct solution. I am sure there should be some methodology for this analysis, but I...

Yes. I can explain you more. I know very litte about topology and manifolds. A rotating laser basically rotates about two axis and generates a response for every angles so in SO2(R). If you watch that video the white line is the scan generated at every instand of time. The scan itself is...

Hi I am working on a robot that has a spinning 3D laser scanner. It rotates about two axis and collects data. In one axis it has full 3D rotation and in another axis it has limit rotation. Now the read world points collect by this laser scanner is not unifomaly distributed but if...

Hi, I am currently studying NIT Trichy(India), 4th semester doing Electronics and communication engineering. I am actively involved in robotics and have also a keen interest in image and signal processing. But my main interest lies in satellite communication and avionics or something that...

happy NEW YEAR to all

Currently i am at home and the circuit is with me, Since it is vacation i don't have access to the lab where the oscilloscope is. So as berkeman advices once the college reopens i will check it out. Thanks for the advice. the reason i am stuck with this shorting problem is because of some crap...

AN IC.. its a 5V digital signal

thanks a lot.. will try it out and let u know..

i am basically using a microcontorller atmega8 to give the switching commant to a RF module.. the RF module IC is some chinese IC which has nearly no datasheet on the net. It is using some ASK mechanism. that's why i resorted to shorting the switch instead of trying to hack the ic. The main...

the problem with relay is that it consumes too much energy. I am trying to short about 4 switches in a digital circuit. which is abt 5 v. and most relays need nearly 9v.

Hello, I have a switch, which is a normal push button switch. It does not latch. I need to design a simple electronics circuit that can be used to short the switch electronically. Any suggestion? I have tried using a transistor switching mechanism but it is not working properly. Any...

I am currently doing electronics and communication engineering, I am aware of my scope. But what concerns me is what field currently has a very good scope for the future. My aim is to enter some space research agencies. I am currently an active member of my colleges Robotics club have done a...

My friend, I was once like you. But don’t loose your Indian education. NIT Calicut is a good college in India. Work hard in their system. Indian Undergraduate program is really good. So instead of Cribbing about your college learn to work hard in the college you are in. I don't think you will...

I need guidance on how to use IEEE. I joined IEEE on entering my college. I got an IEEE membership and now all I have access to is abstract of the papers. It requests me to buy the paper. Can anyone help me and give me advice on how to use my IEEE membership. So far with the limited access I...
