To obviate current beach erosion potentials and as a part of beach re-nourishment, Research department’s Dr. Smith proposed a construction of a series of submerged wave energy dissipation structures (=submerged-plate breakwaters) at 110 ft from the shoreline of the Beach. Based on design specifications of the structure, the distribution of the number of waves dissipatable by the proposed structure per hour could be approximated by a normal distribution with a mean of 189 waves and a standard deviation of 7 waves.
1) Use the Empirical Rule to describe the 90% distribution/range of X, i.e., the number
of waves dissipatable by the proposed structure per hour.
2) If the structure is built with dissipating a maximum 195 waves/hour capacity, what
fraction of an hour, i.e., minutes, might the structure be unable to handle incoming
waves (or in other word, how many minutes per hour the structure exceeds 195
waves/hour capacity)?
3) What wave dissipating capacity of the structure should be built so that the
probability of the incoming waves exceeding the structure capacity is equal to only
0.05 (or 5%)?

Write a python program using the following requirements:

Create a class called Sentence which

  • has a constructor that takes a sentence string as input.
    • The default value for the constructor should be an empty string
    • The sentence must be a private attribute in the class
  • contains the following class methods:
    • get_all_words — Returns all the words in the sentence as a list
    • get_word — Returns only the word at a particular index in the sentence
      • Arguments: index
    • set_word — Changes the word at a given index in sentence to a new word
      • Arguments: index, new_word
      • Does not return anything
    • a str method — Returns the sentence as a string using the built in method

Include a unit test in an if __name__ block to test the class. Use assert to check for errors.

Unit Test Example:

  • Set a sentence variable with a sentence of your choice
  • Instantiate the Sentence object using the variable
  • Test that get_all_words() correctly returns that sentence as a list
  • Test that get_word(#) correctly returns the # word in the sentence
  • Test that replace() actually changes a word in the sentence object
  • Print the sentence before and after the word change using the built in str method

What problems might these new power plants encounter if they were built in South Florida with a lifespan of 40 years?
What advantages are there in giving FPL the licenses for these new plants?
What disadvantages are there in giving FPL the licenses for these new plants?
What are some other alternatives to the nuclear power plants?
What precautions would you demand if these power plants were built?
Given what you know, if you were in a position to approve or disapprove the licenses, what would you vote, and why?

Write a function ‘sort1’ that takes in an array of non-zero positive integers as input and returns a second vector
that contains only the odd numbers. It will return zero if all elements are even. Use error-traps to check against
probable errors in user input. In case of an error, it will return NaN. You are allowed to use Matlab built-in function
round(). Check your code with the following arrays:


>> y1 = [18, -5, 89, -7, 4, 10, 12, 34, -2, 45];
>> y2 = [34, 67, 89, 0, 12, 87, 0, 5];
>> y3 = [ 8, 3, 11, 4, 7, 12, 19, 3, 5, 6]


>> z1 = sort1(y1)
z1 =
NaN
>> z2 = sort1(y2)
z2 =
NaN
>> z3 = sort(y3)
z3 =
3 11 7 19 3 5

** You cannot use any built in Matlab functions other than round(). I don't need all the test runs. I'm just stuck halfway through the code and can't finish it.

1. Explain the following terms in relation to landscape architecture: parterre, Genius loci, tabula rasa, tacit knowing

2. Compare between landscape design as modern professional practice and Landscape design in history. Provide examples.

3. Compare between the French and English landscape design in the history.

Include names of pioneer in the field.

4. Explain the different of built environment and non-built environment in relation to landscape Architecture.

5. Use    your imagination and design the land using only earth. Play with the topography in order to create spaces and corridors. You have a story you want to tell in these spaces. Your words are spaces and paths. Each space or path conveys a message, an image, or a feeling. Through the sequence of spaces, the story will be told. There are no restrictions what so ever to limit your imagination. Only be logical and sensitive. Do the sketch/ sketches in 2 scale. Write any principles you are using in your design related to land form.

The objective of the design problem is to show how you are dealing with the land form; a unique or distinguished design is not required here.

This C++ program will use arrays, recursion, and pass by reference to calculate 02, 12, 22, 32, 42 and then print a message.


Write a driver program (main) that includes the following:


An array class (not a built-in-array) of 5 integers initialized to 0,1,2,3,4 the bases


An integer initialized to 2 to hold the exponent


A string initialized to “Good Job!\n”;


A for loop that calls the recursive pow function with all of the bases and the exponent.


Call the print function with the string using pass by reference by passing the address of s.


You must use the array class (not built-in-arrays) for full credit.


Write a pow function that implements raising a base to a power. The function takes an int base and an int exp. It returns an int which is baseexp. You must use recursion for full credit.


Base case: base1 = base


Recursive case: baseexp = base * baseexp-1


Write a print function that takes a string pointer and uses the indirection operator (*) to print the contents of the string to the screen. This function does not return anything. This function must use pass by reference with pointers for full credit.

First, BICA is considering the purchase of the Empty Arms hotel. Next year's NOI and cash flow is expected to be $2,000,000 and BIC's economic forecast of market supply and demand and vacancy levels indicated they will continue to be in balance. As a result NOI should increase by 1.5 percent each year based upon expected capital improvements, and BIC believes they should earn 9% total return on the investment.

What is the estimated value of the property?

What cap rate should be found from recently sold properties that are comparable to Empty Arms? NOTE how the cap rate reflects the growth in NOI.

Should they purchase this investment if the negotiated asking price is $27M?

Round Tree Manor is a hotel that provides two types of rooms with three rental classes:...

Round Tree Manor is a hotel that provides two types of rooms with three rental classes: Super Saver, Deluxe, and Business. The profit per night for each type of room and rental class is as follows:

Rental Class


Room
Super Saver Deluxe Business
Type I $36 $38
Type II $15 $26 $38

Type I rooms do not have wireless Internet access and are not available for the Business rental class.

Round Tree's management makes a forecast of the demand by rental class for each night in the future. A linear programming model developed to maximize profit is used to determine how many reservations to accept for each rental class. The demand forecast for a particular night is 140 rentals in the Super Saver class, 60 rentals in the Deluxe class, and 40 rentals in the Business class. Round Tree has 125 Type I rooms and 135 Type II rooms.

  1. Use linear programming to determine how many reservations to accept in each rental class and how the reservations should be allocated to room types.
    Variable # of reservations
    SuperSaver rentals allocated to room type I
    SuperSaver rentals allocated to room type II
    Deluxe rentals allocated to room type I
    Deluxe rentals allocated to room type II
    Business rentals allocated to room type II

    Is the demand by any rental class not satisfied?
