Write a function decoder that reads a coded message and outputs the message. The coded message comes in the form of a matrix. Each row indicates one letter. 1 indicates a lowercase letter and 2 indicates an uppercase letter. If all elements in a row are zero, it means a space. Example coded message: Output: I love MATLAB

2.2 Two rods, AC and AD, are attached at A to column AB. Knowing that the force in the upper rod is $F_1 = 150$ N, and that the inclination angles of the rods are $\theta_1 = 30^\circ$ and $\theta_2 = 15^\circ$, determine (a) the force $F_2$ in the lower rod if the resultant of the forces exerted by the rods on the column is to be horizontal, (b) the corresponding magnitude of the resultant.

4. Two important econometric concepts are the stochastic error term and the residual. Carefully distinguish between these two concepts, being sure to: a. Define stochastic error term b. Define residual c. Why must a stochastic error term be present in a regression equation? 5. A source of constant discussion among applied econometricians is the degree to which measures of the overall fit of an estimated equation also measure the quality of that regression. The two most used measures of overall fit are $R^2$ and $adj.R^2$. a. Carefully distinguish between $R^2$ and $adj.R^2$ b. Of the two, which do you recommend typically using? Why? c. Explain (interpret) what is meant by $adj.R^2$=.35? 6. Reflect upon your time at Augsburg. Was there a particular class that made a difference to you? Did you take a study abroad course, become involved in sports, do an internship or be part of a campus organization that transformed your thinking? Was there a professor or a classmate or a staff member that made an impact on you? Describe three examples of things you did at Augsburg that will have a lasting impression. Was there something at Augsburg that helped you find your vocation? 7. Finally, work on your research. Start searching for articles related to your topic. Learn about your topic. As you read the articles, you will learn what past researchers have done on how to analyze your topic. Start summarizing and writing down your summaries. This will become your literature review.

Prob. 2) Relations among fuel element thermal parameters in a PWR Compute the core average values of the volumetric energy-generation rate in the fuel (q''') and outside heat flux (q'') for the reactor types. Use the core average linear power levels and the geometric parameters in the tables in the next page. a) Confirm the power density listed in Table 2-3 for the PWR case. Calculate the specific power of the PWR using Tables 2-3 and 1-3. b) Compute the core average values of the volumetric energy-generation rate in the fuel (q''') and outside heat flux (q'') for the PWR case. Use the core average linear power levels and the geometric parameters in the tables of the next page.
