Good Economics for Hard Times, Banerjee and Duflo address sources of great anxiety across the world.  They argue that the resources to address these problems are there.  What we need, they say, are ideas that will help us reach across the disagreements and distrust that divide us.  They argue for an intelligent government interventionism and a society built on compassion and respect.  

Drawing upon the readings and lectures, give examples of such interventions

A noise source produces sound mainly at 2500 Hz and an SPL of 95 dB at the location of a worker. In order to decrease this worker’s noise exposure, the employer decides to build a brick wall (? = 400 kg/m2) between source and worker. What would the sound level at the worker’s location be after the wall is built. Assume that the wall is perfect and that the sound must go through it (not around it).

Identify the kind of chips – continuous, discontinuous, segmented or built-up edge, that the following workpieces will tend to form under typical cutting (turning) conditions (i.e. not severely high cutting speeds, depths of cut or feeds). Also, state the reason for why that would be the case.

a) Grey Cast Iron

b) Titanium

c) 4140 Alloy steel

d) stainless steel 316

Briefly explain why the following statement is true, false or uncertain.

Suppose you are evaluating a project such as a road where the annual benefits are increasing with calendar time. The present value (PV) of the investment costs of building the road is the same amount no matter when the road is built. In this case the net present value of the project will be increased if the date that the road is completed and ready for service is postponed.

9.) Write a MATLAB script that will read the Pressure and Temperature columns from the provided Excel file. Use a loop to calculate the linear best fit line for the data. You may only use the built-in functions sum, size, and length. Plot both the individual data points (red) and the fit line (blue) on the same graph. Include a title and axes labels.

A, B:   Design and Implement a C# windows form application to ask the user for 10 integer numbers, sort them in ascending order and display the sorted list. Use bubble sort technique to sort the array elements and do not use any built-in sort method to sort the array elements.

C:    Test and evaluate your program by inputting variety of values.

When designing a new warehouse, its size is the most critical attribute. This is because once built, the outer walls of the warehouse form the boundaries within which all operations must take place.

Propose a solution in a essay form with explanations and examples, on how the cubic storage capacity of a warehouse can be increased given a fixed warehouse floor area. (warehouse management)

1)How does the feed forward control loop anticipate disturbance ? Elaborate with an example.
2)It is well known that PLC is used for batch processes; however, SCSADA can be used for continuous processes as well;though, it is built on PLC. How is that possible ?
3) A good example of the application of proportional derivative ( PD ) controller is

please solve the questions at least two questions

however Henry is building a fireplace in his home, the fireplace will require 2500 bricks.

a) if the cost of chimney brick in 2017 $2.10. calculate the material cost of Henry's project in 2020 . the chimney brick index (CBI) was 442 in 2017 and is expected to be 651 in 2020

b) estimate the material cost of similar fireplace to be built in the year 2023
what assumption did you make?
