Detection Definition and 324 Threads

I am reading a radar book about probability of detection and false alarm. The book present the basic idea of the two concepts, but did not go deep into the details of mathematical derivations, which I would like to see. Can anyone suggest some books or online resources (not necessarily has to be...

By what means do scientists detect the presence of elementary particles? How do we know what we are looking at through these means of detection? Thanks

I'm looking to make/buy an RF(radio frequency) to detect and display the level of an incoming RF signal. This is going to be used on a radio controlled vehicle. Any suggestions and info would be greatly appreciated.

Hi, I have the following question: Neutrinos can be detected by an inverse beta-decay. The probability for an interaction of a neutrino and a proton is 10^(-43). How large should be a detector filled with water in order to let interact one of 1 million neutrinos with a proton? What would be...

This probability question came up in our networking tutorial today, and I'm not entirely happy with the TA's solution, so I was hoping someone here could help out. Background: A single parity bit is added to every n bits in a binary string of length 2n. In our class, we add the parity bit so...

I have a question about how neurons respond to stimuli during the relative refractory period of an action potential. During the relative refractory period, it is relatively more difficult for a neuron to undergo another action potential due to hyperpolarization, but it is possible. In general...

hi guys, in our physics class today we were trying to get a more accurate length than the one stated on the device (2.8 cm). We used a microwave reciever and a device that would detect maxima and minima (there was a aluminiun plate at the back which would reflect some wave.) We foun the...

I don't know if my question belongs to this forum but I get some troubles within my approach; what would you think of a theory predicting that some EM fields can exhibit the same (type of) energy-momentum tensor (emt) than the emt associated with some gravitational waves or fields ? Such...

RADAR - Radio Detection and Ranging . Can we use the same technique on a smaller scale :rolleyes: ? I mean to measure the relative velocity between two vehicles :smile: ? Are there any good sources on internet where I can get information in detail about the working of RADAR system...

In the electron detection using Silicon Detector ,Liquid nitrogen is used to cool the system . why is it used. What is "sweating" which is caused if the detector is not in vaccum,when kept in liq. nitogen Thanking you in advance. :smile:

Hi, I'm wondering how do we detect protons, and wat sort of detectors are used for this? Thanks

Hi, does anyone know of something of length of order 10^-21 m? I need it for an assignment to describe the detection of something of that length Regards Ray Veldkamp

Water divining is the common method used to detect an underground source of water. This has no scientific basis. Are there purely scientific methods for detecting subterranean water?

I've got a coursework to get done on the detection methods of black holes. So far I'm aware of gravitational lensing, x-ray detection and the accretion discs, and have just about finished my section on gravitational lensing. I'm wondering though if anyone has some (reliable) links or good...

I'm wondering if someone could tell me what would be the result of the following thought experiment, to help answer a simple question I have about the Heisenberg Uncertainty Principle: (I am just an educated layman trying to figure it all out- hopefully my thought experiment isn't complete...

Hi, I have read some texts on the Internet on neutrino detection but I have some things I hope you can clarify.. When using heavy water (D20) for detection, the neutrino will interact with the deuterium nucleus producing a proton and an electron from the neutron. Now I have read that a...

Since the archive didnt have an answer or these keywords, is there any way to detect a magnet spinning on its axis so the magnetic field is rotating axially and lines of flux are rotating around but nowhere in space is the flux level changing? I've heard rummors over the years. This is not the...

How would neutrons interact with magnetic monopoles?

If I have heard correctly, models of the early universe predict the existence of macroscopic strings brought about by the enormous initial expansion of the universe. A way of proving string theory correct - among others - would be observing such macroscopic strings. My question lies with how one...

Hi all, I am trying to write a code that can determine peaks in a signal. What I am doing is recording a signal then running an fft to calculate the fundamental frequency and the overtones (consonant and dissonant harmonics). The problem is that some of the peaks are very small but are always...

[?] I'm thinking of building a simple cloud chamber in order to detect small particles such as muons, neutrinos, and the like. I have read some handbooks but I would be grateful if someone could lend me a hand by providing some instructions. I only have three months to prepare this so I need the...

Hello, First I will post my question. I think it might be easier if I do this. Now I figure that the counsellor can take two of the four paths to determine if the campsite is down either of them. However, he still must depend on the campers to find out whether the remaining two paths...

[SOLVED] Error Detection Hello, I have a question about error detection. Senario: One person can see two coins. Each coin could be laying heads up or tails up. You cannot see the coins. Question: What is the minimum number of questions with a "yes" or "no" response need to...

Greetings ! I remember posting a partially(I intend to add a different more profound example, if I get some feedback on this enitial message) similar thread here before called "gravitational double slit", but for some reason I couldn't find it. Anyway, basicly I was asking wheather...
