Identify the fundamental mechanisms for x-ray absorption and the relationship for the attenuation of a narrow beam of photons. Define the linear attenuation coefficient and half value thickness. For a typical steel identify how many half-layer values are needed to reduce transmitted energy to 3.1%. Select an example of a steel and determine this samples physical thickness needed to reduce radiation to 3.1 % at 100 keV. [Be sure to identify the steel used including the details of composition and attenuation data used in your calculation.]

Patients arrive at Max hospital for X-ray according to a Poisson process. There is an X-ray machine and arriving patients form a single line that feeds the X-ray machine in a first-come-first-served order. Past data show that the average wait for a patient is 30 minutes. The service time in the process takes, on an average, 10 minutes, exponentially distributed. a)Average number of patients in the system b)Average number of patients in the queue c)Average time a patient spends in...

Thinking about fundamental objectives and means objectives is relatively easy when the decision context is narrow (buying a telescope, renting an apartment, choosing a restaurant for dinner). But, when you start thinking about your strategic objectives -- objectives in the context of what you choose to do with your life or your career -- the process becomes more difficult. Spend some time thinking about your fundamental strategic objectives. What do you want t accomplish in your life or your career?...
