I have a question regarding constructing subway platforms in curved line.
As we know, in a curve, wagons get out of linear alignment and become closer in inner radius and separate from each other in outer radius. I want to know the relation between dimension of car, dimension of structure...
My car currently veers to the right pretty heavily. I need to have the wheel turned very slightly to the left at all times for it not to run off the road. It's been that way for several months now and I'm not too bothered by it. However I just saw my shop has a deal to fix front and rear...
I just want to verify that the dipole moment \vec{m} in the presence of external magnetic field \vec{B} will line up in the the same direction and parallel with the external field. This is according to the right hand rule that if magnetic field is the direction of the thumb, the current will...
A very interesting but speculative paper was published in the Physical Review and arXiv recently about the possibility of the former existence of Cosmic Strings at the point of Electroweak energies.

I know it only happens every 26,000 years, and the sun lines up with the center of the milky way, but is this real or not? And i know it has something to do with the 2012 phenomenon?
In Einstein's 1905 paper he says that, by reasons of symmetry, we can assume the coordinate axis of the stationary and moving frame are aligned.
If the y and z axis rotate towards/away from the x-axis in the moving frame in a way dependent upon the velocity, how does this break the symmetry...
Homework Statement
I am going the do some alignment of a shaft.I use a dial indicator for measurement, and use rim-face techniques. Then I need do calculate the total TIR (Total Indicated Runout).
Here is my result of my measurement (Dial indicator).

Right: +0,08
Bottom: -0,27...
Homework Statement
I need to speed up a image alignment function using FFT
Homework Equations
FFT, correlation coefficient (for deciding best alignment)
The Attempt at a Solution
This function works but a fail to see how it is any better that a naive evaluation of the correlation...
*THIS IS AN ACTUAL QUESTION, NOT A WHAT IF SCENARIO*
I just wondered if it has ever happened or could ever happen that all of the planets align? I'm not saying there are any consequences thereof, just want to know if it's realistically possible, why/why not. Basically just because I think it...
I keep hearing people talking about this as if they know what they are talking about. Would someone enlighten me? Something tells me this could not happen, but I cannot explain what I'm thinking as I am not an astrophysicist or anything. I'm referring to the 2012 hype.
Polarization calculation, "frame alignment"
problem statement
A ray of light (represented by a Stokes vector; coming from a light source) goes through an ideal polarizing filter and reflects off two surfaces (X2 and X1, in that order) and . The goal is to calculate what the stokes vector looks...
Ok. Let me start off by saying I don't believe 2012 is the end of everything. :smile:
However, I have heard about this "planetary alignment" that is suppose to take place. Apparently, scientists have said that either they don't know what affect this will have on us, or that everyone is just...
I saw part of a documentary about the keck telescope, they used an instrument that vibrated if any thing came near it to align the mirror segments, this instrument has fantastic accuracy apparently, can anyone tell me what it is called please.
Hello,
If a magnetic field aligns the electron or nuclear spins can that have a macro effect of causing torque? So for example if we had a rod and we fixed one end but allowed it to freely rotate and then aligned electron or nuclear spins would that cause the rod to rotate?
Thanks,

I was doing a first year imaging lab (in radiography course). We were supposed to check the alignment of the collimation light, and how accurate it represents the x-ray "beam". One of the question in the task question is to determine "the x-ray fields (express this answer in cm and a percentage...
Im trying to solve (approximately) the following problem: Suppose that i have 2 planets with mass m1 and m2 orbiting around the sun and i take into account the following interactions:
a) Interaction between planet 1 and the sun
b) Interaction between planet 2 and the sun
c) Interaction...
Hi all,
I'm interested in learning more about DNA sequence alignment and have been reading up on the topic online.
I'm more interested in the Smith-Waterman algorithm for local alignment, but I'm quite confused about how the algorithm works.
I know the algorithm works on a MxN matrix...
Within the uncertainty of solar system models and their computation, what and when was the closest occurrence (in terms of solid angle) of the inner eight planets forming a radial alignment outward from the Sun?
Hi guys, I want to write up some math and have the following code:
\begin{align}
L_{A}(s)&=V(A,0)-V(A,s) \\
&=\int_{t=A}^{T(A)+A-\alpha S_{A}}e^{-r(t-A)}W_{t}dt - \int_{t=A}^{T(A)+A-\alpha (S_{A}+s)}e^{-r(t-A)}W_{t}dt \\
&=\int^{T(A)+A-\alpha...
my assignment is as follows:
write a programme printing a reasonably sized table of powers, in a nice format. using %nd in printf will write an integer in at least n charcaters. this facilitates printing tables with aligned columns.

The question is on the behavior of the magnetic and spin axes in a strong B-field (the Paschen-Back Effect, I believe it's called. Anyway...). I've got almost everything nailed down, except for one thing. In the example I've looked up...
I was wondering if there is a way to align an atoms electron cloud-orbit/probability of location to one side of an electron. For example the probability of the electron being on the closet side or being in a regular area at a regular time. i.e. regular orbit area, and or keeping the electrons on...
Ok so if the center sun of our gallaxy is in sagattarius then what degree is it in sagattarius. If the Earth and the sun and the center sun were in aline once a year then would I have to see the oppisite consalation of sagattarius at the oppisite degree of the center sun in the center of the...
With a combination of wave plates in the order \lambda/2 - \lambda/4 - \lambda/2 it should be possible to achieve any polarisation. But I don't understand why: the first wave plate switches the polarisation direction, the second changes linear to circular polarisation and vice versa, and the...
I recently switched cartridges but forgot to re-align the printer. As a result each time I print, the words are a bit blurry. My printer is 'hp psc 2410 photosmart'. How can I re-align?
Hi everyone,
I have a question about the mechanics of the magnetic field alignment process. If you suddenly subject some iron filings to a magnetic field, they align along the magnetic field lines. I'd like to know how this happens step by step. I understand that the iron filings which were...
