determine the section modulus of the sheet pile per unit length.

 

A cantilever sheet pile wall is driven into undrained clay and then back-

filled with granular soil. The groundwater table is at the dredge line.

The sheet pile and the soil characteristics are shown in Figure 7.57.

Determine:

(1) The depth of the embedment, D, using a factor of safety of 1.5 for

strength reduction.

(2) The maximum moment on the sheet pile.

(3) Given the allowable flexural stress of the sheet pile, all =

150 MN∕m², determine the section modulus of the sheet pile per

unit length.

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….
