Determine the minimum factor of safety of the slope, using Taylor’s chart (Figure 5.41).

A natural slope is shown in Figure 5.41. It contains two soil strata. The

slope configuration and the soil characteristics are shown in the figure.

A potential toe circle with radius of 70.0 m passes the coordinate of

(65 m, 30 m). The toe is at the origin (0, 0).

(1) Determine the average cohesion, friction angle, and unit weight of

the slope and foundation soils.

(2) Determine the factor of safety of the slope along the assumed fail-

ure circle.

(3) Determine the minimum factor of safety of the slope, using Taylor’s

chart (Figure 5.41).

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).

Suppose a PET detector comprises four square PMTs (arranged as a 2 by 2 matrix) and a single BGO crystal with slits made in such a way that it is….
