determine the minimum fac- tor of safety (FS) for the slope.

 

A natural slope is 35 meters high and the slope inclination is

2(H):1(V). The slope’s properties are: c′ = 50 kN∕m², ′ = 25°, and =

19.0 kN∕m² .No firm layer was encountered beneath the slope during

the subsurface investigation. Downward steady seepage that is

parallel to the slope surface occurs in the slope. The average pore

water pressure ratio for the slope was determined to be 0.4.

(1) Use Bishop–Morgenstern method to determine the minimum fac-

tor of safety (FS) for the slope.

(2) Use Spencer charts to determine the FS.

(3) Use Michalowski charts to determine the FS.

Explain why attenuation is not a big problem in PET.

Consider a 2-D object consisting of two triangle compartments, as shown in Figure P9.4. Suppose a solution containing a 511 KeV gamma ray emitting radionuclide with concentration f = 0.5….

Give the mean and the variance of the reconstructed image, mean[ˆ f(x, y)] and var[ˆ f(x, y)].

Ignoring the inverse square law and attenuation, an approximate reconstruction for SPECT imaging is given by where c˜() =  {||W()} and W() is a rectangular windowing filter that cuts off at = 0…..

Find the numerical responses in each to an event in crystal C(4, 6).
