a) Generate expressions for the undamped natural frequency ω n and the damping ratio ζ in
terms of k , m , and c .

b) If the spring constant k is increased, but m and c are unchanged, predict whether ω n will increase, decrease, or remain the same. Justify.

c) If the spring constant k is increased, but m and c are unchanged, predict whether ζ will increase, decrease, or remain the same. Justify.

You are attempting to value a put option with an exercise price of $105 and one year to expiration. The underlying stock pays no dividends, its current price is $105, and you believe it has a 50% chance of increasing to $122 and a 50% chance of decreasing to $88. The risk-free rate of interest is 10%. Calculate the value of a put option with exercise price $105. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

Please provide ALL documentation stated at the bottom (in bold) for each circuit

Description: Build and test the following circuits using gate-level modeling in Verilog HDL.

1. 3-input majority function.

2. Conditional inverter (see the table below: x - control input, y - data input). Do NOT use XOR gates for the implementation.

3. Two-input multiplexer (see the table below: x,y - data inputs, z - control input).

4. 1-bit half adder.

5. 1-bit full adder by cascading two half adders.

6. 1-bit full adder directly (as in fig. 4.7 in the text).

7. 4-bit adder/subtractor with overflow detection by cascading four 1-bit full adders (see fig. 4.13 in the text). Use multiple bit variables (vectors) for the inputs and output (see 4-bit-adder.vl)

Requirements:

1. Create truth tables and use maps for simplification (not needed for circuits 5 and 7).
2. Create a module for each circuit, instantiate it in a test module and test it.
3. The hierarchical circuits (5 and 7) should use instances of their constituent modules.
4. For testing use  all combinations of input values and show the corresponding output for all circuits except for the 4-bit adder/subtractor.
5. No need to use all possible inputs for testing the 4-bit adder/subtractor. You may pick one positive number, one negative number and 0, and then add and subtract all combinations of two of them. Test also overflow situations and show the inputs/output both in binary and signed decimal.

Documentation:

***************Write a project report containing for each circuit:***************************

1. Short text description.
2. Truth table and map for the functions that can be simplified (not needed for the hierarchical implementations 5 and 7).
3. Gate level circuit diagram with components and wires labeled with the names as used in the Verilog code. Use block diagrams for the components of the hierarchical circuits.
4. HDL source code (included as text, not image).
5. Verilog output showing the test results as explained in the requirements.

Many national brands are supplying products to be sold by retailers under the retailer’s own private label. For example, Purina, Borden, Heinz – have all admitted to supplying products (sometimes lower in quality) – to be sold under the retailers’ own label. The practice has been criticized by many, as it might create confusion for consumers and reinforce the perception that all brands in a category are “the same”.

What is your opinion on this matter? Should national brands manufacturers also supply private label brands? If so, should the quality be lower?

Felix Baumgartner, an Austrian skydiver and daredevil, made history’s highest and fastest jump. After ascending to more than 128,000 feet in capsule tethered to a helium balloon, Baumgartner jumped and became the first human to break the sound barrier as he fell at a rate of 833 miles per hour and had a free-fall of more than 4 minutes.

The event was sponsored and funded by Red Bull – a company known for pushing the envelope of crazy and risky sports.The company doesn’t consider this a stunt though, preferring to characterize the program as a professional flight test program. Red Bull spent more than five years on the project with an expert staff of scientists, engineers, and physicians – many of whom had experience with NASA programs. The cost to Red Bull has not been disclosed, but estimates on the return to the company in regards to visibility, branding, and goodwill tops $8 billion.

Why do companies sponsor events – oftentimes events that seem to have little to do with their products?

What do companies gain? What do they risk?

How does the Stratos project fit with the Red Bull brand and target market? How does it fit with other promotional tools used by Red Bull?

1. In general, the marginal cost curve is U-shaped as you learned in lectures and the textbook. However, exception exists. Please provide one particular industry as an example to illustrate that MC is not U-shaped. Explain briefly the shape of MC in the industry. 2. Engineers at a national research laboratory built a prototype automobile that could be driven 180 miles on a single gallon of gasoline. They estimated that in mass production the car would cost $40,000 per unit to build. The engineers argued that Congress should force U.S. automakers to build this energy-efficient car. In your opinion, is energy efficiency the same thing as economic efficiency? Please explain your opinion and state whether you support it or not.

A lease has five annual payments of $115,000. The leased asset would cost $500,000 to buy, would be depreciated straightline to a zero salvage value over 5 years, and has an actual salvage value of zero. The firm can borrow at 8 percent on a pretax basis and has a tax rate of 23 percent. What is the net advantage of leasing?

Intructions

For this assignment you will be creating two classes, an interface, and a driver program:

• Class Calculator will implement the interface CalcOps
  o As such it will implement hexToDec() - a method to convert from

  Hexadecimal to Decimal.

• Class HexCalc will inherit from Calculator.

• Interface CalcOps will have abstract methods for add( ), subtract( ),

  multiply( ) and divide( ).

• Both classes will implement the CalcOps interface.

o Class Calculator’s add, subtract, multiply and divide will take in 2 integers and return an integer. If you prefer it can take in 2 strings, and return a string.

o Class HexCalc’s add, subtract, multiply and divide will take in 2 strings (hexadecimal numbers) and return a string (hexadecimal number).

This Calculator class will work with whole numbers (int) and hexadecimal (String) values. The hexToDec ( ) method is a helper method included in interface CalcOps, that requires the Calculator class to implement the method which converts hexadecimal numbers to decimal. (Hint: Use language specific utility methods to convert hexadecimal to decimal.)

OUTPUT

===================================================

(a) Create a class Webcam which stores the information of a webcam. It includes the brand, the model number (String) and the price (double, in dollars). Write a constructor of the class to so that the information mentioned is initialized when a Webcam object is created. Also write the getter methods for those variables. Finally add a method toString() to return the webcam information in the following string form. "brand: Logitech, model number: B525, price: 450.0" Copy the content of the class as the answers to this part.

(b) Create a class ComputerShop which stores the webcam information in a map webcamMap, whose key is the concatenation of the brand and model number, separated by ": " (a colon and a space). The value is a Webcam object. Write a method addWebcam(Webcam oneWebcam) which adds oneWebcam to webcamMap. Copy the content of the class, which any include import statement(s) required, as the answers to this part.

(c) Create a class TestComputerShop with a main() method which creates a ComputerShop object aShop and add the first webcam with brand "Logitech", model number "B525" and price 450.0. Add the second webcam with brand "Microsoft", model number "HD-3000" and price 235.0. Copy the content of the class as the answers to this part.

(d) Write a method showWebcam() of ComputerShop which loops through the keys of webcamMap using the enhanced for-loop and directly prints each webcam object stored using System.out.println(). (Loop through the values is simpler but using the keys is required in this part.) This should show suitable information since the method toString() has been written in (a). Add a statement in TestComputerShop to display all the webcam information of aShop. Copy the content of the method, line(s) added and execution output as the answers to this part.

(e) Write a method modelNumberSet() of ComputerShop which returns model numbers of the webcams in a set. You should loop through the values of webcamMap using the enhanced for-loop and collect the model numbers. Add a statement in TestComputerShop to display the set using System.out.println(). Copy the content of the method, line(s) added and new execution output as the answers to this part.

(f) Write a method priceList() of ComputerShop which returns the prices of the webcams in a list. You should loop through the values of webcamMap using the enhanced for-loop and collect the prices of the webcams. Add a statement in TestComputerShop to display the list using System.out.println(). Copy the content of the method, line(s) added and new execution output as the answers to this part.
