What to do

This assignment is going to be pretty simple - we're just going compute frequency counts of certain colors in certain ranges (Histogram of the image).

Because there is no natural way of segregating RGB color ranges, we usually do this color by color. So you'll be computing frequency counts for individual color components individually.

The expectation is that you will write a function as described by a python function signature below (while you are free to do whatever you want, I think doing future parts of the assignment will be easier if the code is structured this way) -

Think about what happens when one is comparing images of different sizes -

• Lets say A is an 4 by 4 image where half of the colors are gray (rgb(128, 128, 128)), and the other half is white (rgb(255, 255, 255))
• When you compute frequencies for Red component, you'll find that 128 occurs 8 times and 255 occurs 8 times also.
• Lets say B is an 8 by 8 image where half of the colors are gray (rgb(128, 128, 128)), and the other half is white (rgb(255, 255, 255))
• When you compute frequencies for Red component, you'll find that 128 occurs 32 times and 255 occurs 32 times also.
• This would mean that images that are basically the same in terms of colors (both half gray and white), end up with different histograms.

To make sure similar images have similar histograms regardless of image size, it is good to normalise frequencies by dividing each frequency count by the total number of pixel in the image.

• After normalization, frequency for red 128 in A would be 8 / (4 * 4) = 0.5
• After normalization, frequency for red 128 in B would be 32 / (8 * 8) = 0.5
• You will be given an image as a text file in the format we've been using so far - assignment_files.zip

How much heat (in kj) is needed to convert 866g of ice at -15*C to steam at 146*C? (Note: The specific heat of ice is 2.03J/g*C and the specific heat of steam is 1.99J/g*C. Delta fus for H20 is 6.01 kj/mol and Hvap is 40.79kj/mol)

As everybody knows that Black objects are black because almost all the light that falls on them is absorbed into the material. Little or no light is reflected back toward our eyes, therefore we see black.

It is also known that, since black objects absorbs all the light they ultimately become heated-up..!

If we see the snow in visible light, It appears to be White. But in the Infrared, it appears to be black. Does that mean that the Snow will feel warm in Infrared lights?

b) in one year their sales would drop by 50%.

Calculate the pH during the titration of 25.00 mL of 0.1000 M LiOH(aq) with 0.1000 M HI(aq) after 24.2 mL of the acid have been added. Explain.

1. How do the following terms relate to bonds?
   1. Indenture
   2. Registered form
   3. Sinking fund
   4. Call provision
   5. Protective covenant
   6. Zero coupon
   7. Bid-ask spread

2. Use the data provided below and calculate:

1. Nominal GNP for 2014 and 2015.
2. Assuming 2014 is the base year, calculate price index for 2015.
3. Real GNP for 2014 and 2015.
4. Inflation rate from 2014 to 2015.
5. Real and nominal rates of economic growth from 2014 to 2015. (Note, rate of change is measured by “absolute change” from one year to another divided by what the GNP was in the previous year.

Consider a GaAs p-n junction diode. The p-type acceptor is Zn, with a dopant concentration of 2 x 10^17 cm^-3 and the n-tpye donor is Si, with a dopant concentration of 5 x 10^16 cm^-3. Working at temp= 300 K.

a) Calculate the Fermi Level in the p-type material. Assume that the hole density is equal to the density of the p-dopant atoms.

b) Performing the same calculation for the n-type material gives a fermi level of 1.363 eV. What is the zero-bias built- in potential at the junction?

c) Calculate the width of the depletion zone for this case

The Ka’s for H₂SeO₂ are K1 = 2.7 x 10^-3 K2 = 2.5 x 10^-7 Calculate the pH of a solution formed when 30.0 mL of 0.25 M KSeO3 is mixed with a) 1.5 mL of 0.20 M KOH b) 20.0 mL of 0.25 M HCl c) 25.0 mL of 0.20 M K₂SeO₃

I know how to calculate pH's however, I do not know when to use K1 vs K2, can you explain please?

Textbook publishers must estimate the sales of new​ (first-edition) books. The records indicate that 25​% of all new books sell more than​ projected, 30​% sell close to the number​ projected, and 45​% sell less than projected. Of those that sell more than​ projected, 55​% are revised for a second​ edition, as are 40​% of those that sell close to the number​ projected, and 25​% of those that sell less than projected.

a. What percentage of books published go to a second​ edition?
