What is Resolution: Definition and 309 Discussions
Dispute resolution or dispute settlement is the process of resolving disputes between parties. The term dispute resolution is sometimes used interchangeably with conflict resolution, although conflicts are generally more deep-rooted and lengthy than disputes. Dispute resolution techniques assist the resolution of antagonisms between parties that can include citizens, corporations, and governments.
Hello! I am doing some calculations and I would like to use the best value for a micro channel plate (position sensitive) position resolution to date. I don't care too much about the details, but I don't want to use too small of a value and of course I'd like to give a reference for this value...
Objectives:
- best path for optics needed to focus and "draw"/project a high resolution image onto a workspace around 500mm square (for a Laser Direct Imaging machine)

Hi
Sorry about the stupid question. I am completely green on tv streaming. I have a limitation of 25MBPS internet connection. I know 4K video needs 25MBPS speed. That is I can ONLY run one tv.
I really don't care about the clarity and resolution. I have modern smart tv, but I am still feeding...
My notes say that the Resolution of the Aperture(in the Electric field of the wave) is the Fourier transformation of the aperture.
Then gives us the equation of the aperture:
and says that for the circular aperture in particular also:
My attempt at solving this:
We know that the Fourier...
Hello! If I want to model the time and spatial resolution of an MCP detector, should I use a gaussian or a uniform distribution? I imagine that, for example for the spatial distribution, the uncertainty is given by the size of the pixel on the detector, which makes me think that uniform...
In the video above we can see the wave like patterns. The microscope on the video, used on the experiment, has a low quality and a low magnification. If anyone has a scientific article or a video source for such experiment with low magnification but with a high quality of definition it would be...
This is not really a homework question so don't bother answering them. It is more of a guidance problem. This is what I find the hardest out of all topics.. Unfortunately, this topic is a fixed 10 marks question in our 80 marks exam. Comes every time.

Hello Gentlemen,
I'm not an EE engineer, yet trying to help my colleagues. I would like to get a general feeling of what could be going on.
Probably trivial for some of you.
Background
We have a motor/torque sensor device that is measuring torque values. We get out digital signals for Torque...
I was wondering how the resolution is of a observatory station and compare that to its field of view? Higher rez with larger field or higher rez with more narrow field but much more scanning across the sky to create full images?
It just occurred to me while watching some old X ray images , what is the reason behind why modern X ray images have so much more detail than older ones especially really old ones from the beginning of the technology at the start of 20th century?
I ask this because (unlike in a CT scanner which...
Hello Forum,
I am attempting to understand what causes pixelation when a bitmap (jpg, png, etc.) image is enlarged.
Bitmap images have a resolution indicated as the number of pixels along the width and height of the image itself. On the other hand, computer monitors also have a physical...
Hi guys,
I have started studying differential equations on my own, sticking to my last high-school year's textbook, along with a few physics applications of ODEs.
Online I came across the n-body problem, which then took me to the basic two-body problem!
I'm here to ask you a few things about...
Hello,
This question is with regards to the discussion around page 56 (1971 Edition) in Anthony French's Newtonian Mechanics. He is discussing the choice of a coordinate system where the axes are not necessarily perpendicular to each other. Here is the summary of what I read (as applied to...
Hello folks,
I have the two following questions I'm working on:
Q1
An optical microscope uses a lens with NA = 0.7 and a focal length of f = 20 mm. What is the smallest spatial distance that can be resolved if a wavelength of λ = 633nm is used? An iris is introduced in front of the lens with a...
Can anyone help me solve the magnitude and direction of force at C.
I've managed to get a value for AB. Using basic trig and substituting into F= ((9x150+19.62×350) / 50) / cos9.782
Therefore producing an upward force at AB=166.7N
when it comes to force @ C.. I'm lost!

In the section 8-2 dealing with resolving the state vectors, we learn that
|\phi \rangle =\sum_i C_i | i \rangle
and the dual vector is defined as
\langle \chi | =\sum_j D^*_j \langle j |Then, the an inner product is defined as
\langle \chi | \phi \rangle =\sum_{ij} D^*_j C_i \langle j | i...

Hi
I want to look at the energy resolution of a homogeneous calorimeter, in the literature I found that is given by
σ/E = a ⊕ b/√E ⊕ c/E and I found that the ⊕ means quadratic sum, what does quadratic sum mean?
Thanks

Hello everybody!
I have a question regarding my physics laboratory at the university. I am performing the measure of muon lifetime. The setup is quite standard (coincidence measurement with plastic scintillators).
My question is about the time resolution. I have tried to see if the time...

Hi everyone,
this is sort of a soft question which I need to ask to make sure my understanding is correct, it relates to a little project I'm doing on measurement resolution. The first question is to clear up a general concept, the second is based on the first and is the actual question...

The positive lambda has a quark composition udc, and a lifespan of 2 x 10 minus 13 seconds. When this particle is created in a collision, inside a modern detector, how long will its track be? At near the speed of light, its lifetime would allow it to traverse less than a tenth of a millimeter...

Hi!
Am new to this forum, but I have looked around here for some time now, since am studying a course of logic in the context of computer science. I have a very important exam in a few days, and while I thought I got it, I got shocked when I was looking on previous graded exams to see what I...
Hi,
I read the Feynman Lectures Volume 1, Chapter 27, section 27-7, which can be here. In the lecture he describes the fundamental limits of resolution and provides a criterion.

There are two light sources, ##P## and ##P'## There is an...

The process is known as counter-propagating Spontaneous Parametric Down-Conversion (CP-SPDC).
In regular SPDC, a photon from a (pump) laser enters a transparent nonlinear crystal at rest, and gets converted into a pair of photons whose total energy and momentum add up to that of the original...

Dear all,
We were trying to solve the following question but did not quite understand what to do. The question is as follows:
The reconstructed invariant mass is usually described by a Gaussian (or Normal) distribution. However, the resolution σ (the width of the distribution) is found to...

I've often wondered at the "resolution" of the human visual system but it's not at all clear from what I've read whether this question even makes sense. As a sort of general position, many of the articles I've read suggest that the human eye, over the full field of vision, delivers around...

I know localisation microscopy 'beats' the limit on resolution by activating individual sources and rendering a final image, but what are the limits that prevent the resolution of the images of these individual fluorophores?
Is it just the number of photons collected?
