Write a JAVA program to model the kinds of people one finds in a university. The categories are students, teachers and teaching assistant (TAs). All these categories are kinds of Person (Person is abstract class. A teaching assistant (TA) is a student and a teacher as well. A person has a name (string). A student has grade point average GPA (between 0 to 4), the teacher has the number of scholarly papers he/she has published and the teacher assistant has the number of courses he/she assists. All the classes contain constructors with default arguments to fill all data spaces. Provide display method to print all data members of an object on the screen. Classes also contain a function called isSuccessful(). Students with a GPA over 3.5 are considered successful. This function returns true if someone is successful or false if not. In main(), define an array of Person class, which can point to students, teachers and teacher assistants. The program first asks the kind of person and then lets…
Implement the problem below in Python using mpi4py. Submit the code of your program and a brief report. The report should describe the design of your program, and demonstrate the results of running your program. n-body solver. Implement a parallel n-body solver with n = 10 particles. You may randomly generate the masses, initial velocities, and initial positions of all particles at the beginning. Compute the positions of all particles after 1 second. Compare the results by using 0.1s, 0.01s, and 0.001s as the time in each timestep, respectively.
You will be using on RV related review comments to train a Sentence completion model. You could use the code below. The code is written in Jupyter notebook python. please follow the following instructions: 1. Build a working sentence completion model. Training data is provided in train.csv. This model should take partial sentences (e.g., "hey how ar," "hello, please") and provide completion for that sentence. Not every input needs to be completed into a correct sentence (e.g., "asdfauaef" does not need to have a sentence completion). For this model's purposes, a sentence is considered completed if an "end of sentence" character (like a full stop, question mark, etc.) occurs within the next five words OR. We predict up to 5 words from the input. 2. BONUS: If you use word vectors or other techniques from what we shared in class using character encoding and have a working model. 3. The test data (test.csv) will be used to evaluate the model. The test file contains partial sentences. Use…

What is the probability that in a classroom of x people, at least 2 will be born on the same day of the year (ignore leap year)? Use a Monte Carlo Simulation and a frequency table to write a program that calculates this probability, where the number of people (x) in the simulated class is given by the user. The probability for a class of size 23, should be right around 50%. NO language of "break" or "true" please! Please use the outline given below for the code:
