I have seen what looks like newtons rings interference pattern in transverse CT images of 2 solid water block on
top of each other. My understanding is that newtons rings occur in visible light eg photography or scanners. Can anyone shed some light on this? :)
If we know the max. pressure (p) is 2.5 MPa and T = 20 C.
Peak intensity, I = p^2 / rho * c
where rho = density of water: 0.9982E03 kg/m^3 and c = speed of sound in water: 1482.3 m/s at 20 C
I = (2.5E06 [Pa])^2 / 1.4796E06 [kg/m^2/s] = 4.2241E06 W/m^2
Is this correct?
I am trying to use Bayesian methods (Bayes rule) to predict further datapoints (at point n,n+1,n+2 etc..)...
I begin by generating a normal pdf using previous 75 datapoints (prior: n-75 to n-1) with mean value, μ: 1.25 and standard deviation, δ: 3.67.
Note: previous datapoints range from...
I found that factor online.It said to get intensity to < 1% but by my calculations, for 200 KeV beam using formula:
HVL = 0.693/u
need 7 HVL layers to get to 0.8% which is 4.48 mm.
where u = 10.15 cm^-1
equation for radius of curvature of relativistic electron in magnetic field?
is this correct:
R = gamma * m * v / e * B
where gamma is lorentz factor, m is electron mass, v is velocity, e is electron charge and B is magnetic field strength.
Can i use box muller transform to generate a distribution with two different sigma (i.e. sigma_x and sigma_y)?
I want to generate a random gaussian angle (C) relative to z axis on circle plane, then set the angle relative to the x, A and y axis, B, wrt to the original angle.
However, I want...
How to rewrite this 2D Gaussian eqn in terms of x?
i need to calculate the x and y values.
let x0=0 and y0=0.
is it complex?
