Use the method of eigenfunction expansions to solve the following heat flow problem with external heat source in a one-dimensional rod:
∂u=2∂2u+e−(x+t) 00, ∂t ∂x2
u(0, t) = 0, u(π, t) = 0, u(x, 0) = −x.
You can use the provided formula sheets.

"Please write a program in Java to sort and search hotel booking information. The public interface of BookingManager is described below, along with a ready-to-use class BookingInfo. Please follow the requirements in the description for each method to complete this class. Please also write a tester class to thoroughly test the four methods given in BookingManager.
The BookingManager class should contain the following public methods:
1. public ArrayList readBookings(string pathName) throws IOException:
a. Read all the booking information from the binary file in the local file system as specified by the parameter pathName and return an ArrayList of BookingInfo.
b. We assume that each record in the binary file has a fixed length of 60 bytes, with start date stored in the first 20 bytes, end date in next 20 bytes, and id in the last 20 bytes.
c. We assume that all the dates in the file are in the format of YYYY-MM-DD. There could be an arbitrary number of records in the file.
2. public ArrayList sortBookings(ArrayList inputList):
a. Write code that implements the merge sort algorithm to sort all the booking information in inputList by start date in a way that recent info shows first. The method returns the list of sorted bookings.
3. Public ArrayList removeConflicts(ArrayList inputList):
a. Use the sorted list of booking info (inputList) to find if there are pairs of bookings with conflict. Having a conflict means that a booking has a start date before the end date of another booking. Whenever there is a conflict, remove the later one. The method returns a new list of booking info with no conflicts.
4. public void saveBookingInfo(String pathName, ArrayList sortedList) throws IOException:
a. Use RandomAccessFile to save all the ordered booking info from the sortedList to the given pathName on the disk.
5. public ArrayList bookingSearch(String pathName, Date minDate, Date maxDate) throws IOException:
a. Given the date range [minDate, maxDate] (both inclusive) and the pathname of the file that stores the sorted booking info, use binary search to find and return an ArrayList of all the booking info within this date range without loading all the booking info in the file into memory (i.e., do NOT attempt to read all booking info into an array/ArrayList and then perform the search there). If no booking info falls in the date range, the method returns an empty list. As a hint, one way to complete this method is to adapt the binary search algorithm (for arrays) taught in class to the setting of random access files. To retrieve the booking info in a range, you may use binary search to locate within the range the booking info with the given minDate (or if such a booking info does not exist, the first booking info that has a start date that is higher than minDate in the file) and then visit the subsequent records until the date is out of the given range or the end of the file is reached.
b. Tips: 1.Use RandomAccessFile().seek(long pos) to do random access;
2. Use RandomAccessFile().length() to get the size of file (number of bytes)."

Your boss gives you a task at your company, saying, "I need you to go into the local community and collect some observation notes for me. I want the notes to answer the question, 'how would you describe people's cell-phone usage?' Find a nice place to go where there are lots of people and report back to me what patterns you found and your interpretations. Can you do that?" Using what you learned in class, briefly (1) describe how you would answer this question as an 'ethnographer' and (2) explain how you know your interpretations would be considered "right."

Your boss asks an important question you can only answer. "I noticed lately that no one is really motivated, everyone is resistant to change, and everyone is indifferent to my ideas because they just want to follow my directions rather than give feedback. What do you think I should do?" Using the Human Resources management approach, briefly (1) identify in one line what theory (X or Y) best fits the current workplace, (2) list the primary tenets of the theory (X or Y) you think your workplace can benefit from and (3) provide at least two recommendations telling your boss what they should do to change the workplace.
