Write a OOP class called BookList that uses a Book class and allows multiple books to be entered into a BookList object. Include normally useful methods and boolean addBook(Book b), Book searchBook(String title, String author). addBook returns true if b is successfully added to the list. searchBook returns a book matching either the title or author from the current list. You do not need to write Book (assume there are suitable constructors and methods) or any test code (main). You can write them if you wish. Use Java or other language if you wish; use any IDE or compiler.

Hydraulics & Hydrology

Problem Statement

The Romans were exquisite water engineers, and that without having at their disposal the modern tools and the knowledge we have today. Remember that Hydraulics and Hydrology as we know it now only came to be in the 1700’ when engineers started to put a fundamental framework together that is/was based on lab experiments and theoretical approaches and principles. Until then, you just “knew”. The Romans build all sorts of hydraulic systems, from irrigation canals, to water supply infrastructure, to the famed “hot baths” of Rome, to sewer systems, you name it. They realized that if you want water for different purposes at locations that were important to you that very often you had to get the water there because it just was not available in close proximity.

One of the marvelous feats they accomplished was to build water supply systems that would run over dozens of miles to convey water from sources to locations of need, typically the towns and cities they founded in their vast empire. They managed to do so by building a lot of infrastructure that withstood time and that, almost 2000 years later, is still in place for us to marvel at. Especially the many bridges that were built to cross valleys and gorges to keep the supply line flowing as an open channel are spectacular in their construction, such as the Pont du Gard, Segovia, and Aquila aqueducts.

Task:

1. Create a small inventory of the 5 most prominent and well-known aqueducts around to this day (you make a decision on what the criteria are for the selection of the 5). Come up with some describing parameters (for sure show an image or two) such as location, total length, capacity, year of built, special features, how many bridges, building materials, etc. Be creative and decide on your own what you want to tell about them.

2. Pick one of them and carry out a hydraulic analysis. I am interested here in typical characteristics such as discharge capacity, slopes, cross sections, but also operation: how did you get the water into the aqueduct, control structures, terminal end structures, Manning’s “n”, ... But also how they were lined, how gaps between construction elements were sealed so no seepage (or losses) would occur. It would also be great if you could treat the aqueduct as a chain of: uniform, rapidly (around controls), and gradually varied flow sections. Carry out a few analyses steps and report on what happens to energy and friction grade lines in these sections, preferably of the entire length of the aqueduct.

Create a Python program that:

Reads the content of a file (Vehlist.txt)
The file contains matching pairs of vehicle models and their respective makes
Separate out the individual make and model on each line of the file
Add the vehicle make to one list, and the vehicle model to another list; such that they are in the same relative position in each list
Prompt the user to enter a vehicle model
Search the list containing the vehicle models for a match
If a match is found, display the vehicle make by accessing the vehicle make list entry in the same relative position the match was found
If no match is found, display a message saying so to the user
Allow the user to enter name for the file
The program should:

Use variables with meaningful names
Display easily understood prompts when collecting user input
Have appropriate comments indicating what each part of the program is doing
Have a comment area at the beginning of the program identifying the author of the program and the class it was created for
Save the program as a Python module, and submit the program through this assignment

Question 2 (Function Template)

Write a template version of the iterative binary search algorithm that searches an array of arbitrary type for a given key.

Declare and implement a class called Student that keeps the student id, name, and grade. Include a default constructor, the overloaded insertion (<<) operator and also the overloaded extraction operator (>>).

Declare and implement another class called Book that keeps the book’s title, author, and price. Just like the Student class, Include in class Book a default constructor, the overloaded insertion (<<) operator and also the overloaded extraction operator (>>).

Write a main() function that test your function by passing parameters of type int, float, char, Student, and Book. Identify and implement additional suitable operators needed to be overloaded in the Student and Book class that you define above so that it can work well with the template binary search function that you have written. A Student object should be searched using the student id and the Book object should be searched using its title.

4. You are given an animal whose development has never been characterized before. You note that at the four-cell stage, one blastomere transiently shows dark pigmentation. However, as embryogenesis proceeds, the dark pigmentation fades and you are unable to determine what becomes of the blastomere in the fully-developed embryo.

a) [4pts] Describe a simple experiment you can do to determine the fate of the dark blastomere. Provide sufficient detail to show that you understand the technique and its interpretation.

b) [5pts] For the animal described above, you find that the dark-pigmented blastomere at the four-cell stage ultimately gives rise to all of the central nervous system of the embryo. Using this information, devise an experiment to determine whether this cell is specified to be CNS at the 4-cell stage. In addition to describing the experimental procedure, describe the possible results and how you would interpret them.

c) [1pt] As this embryo undergoes gastrulation you notice that the ectodermal cells surround the endoderm similar to Xenopus. What is the name to describe the movement of these ectodermal cells?
