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%)?

Instructions: Florida Power and Light (FPL) are seeking to add
two more nuclear power plants on the current Homestead location
where two nuclear power plants already exist.
FPL seeks two more South Florida nuclear reactors article
http://articles.sun-sentinel.com/2014-05-12/business/fl-fpl-nuclear-preview-20140512_1_turkey-point-fpl-reactors
Based on what you have learned so far from this class, discuss the
following:
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

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: 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.
| 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 |
