Describe the ISA memory format?

Write a Matlab/SciLab function that accepts inputs as degrees and computes the equivalent within the interval 0 to 360.

function de=equivalent(d) For example, equivalent(540) = 180 equivalent(-30) = 330

Sovle with python 3.8 please.

1, Write a function called same_without_ends that has two string parameters. It should return True if those strings are equal WITHOUT considering the characters on the ends (the beginning character and the last character). It should return False otherwise. For example, "last" and "bask" would be considered equal without considering the characters on the ends. Don't worry about the case where the strings have fewer than three characters. Your function MUST be called same_without_ends. You can write code in the main part of your program to test your function, but when you submit, your code must ONLY have the function definition!

2, Write a function called replace_es_with_threes that has a single string parameter. It should return a version of the string where all instances of the letter e have been replaced by the digit 3.

Your function MUST still be called replace_es_with_threes. You can write code in the main part of your program to test your function, but when you submit, your code must ONLY have the function definition!

Please answer with a fully detailed solution with examples.

In Java, write a method to determine if a string contains only digit characters.
In Java, write a method on how to find each occurrence of a letter given a string.

How do you split a pandas column with floating numbers on a symbol. For example:

COLUMN = Location

ROW = 44.567892, -83.783937

Split the numbers into two separate columns based off of the comma. Meaning 44.567892 would be in its own column and -83.783937 would be in its own column. In python

Define sockets

A limitation of the chat server is that it can handle only one client because it is a single threaded application. Using the pThread library, modify the chat server so that it can handle multiple clients simultaneously, i.e., by creating a new thread whenever a client is connected so that the client is handled individually with a new thread, and at the same time, by having the main thread (i.e., the thread that runs the main function) of the chat server continue to wait for an incoming connection from a client.

The current implementation of the chat server allows the server to exchange messages with a client individually. Modify the server code so that when the server sends a message, that message is sent to all connected clients. We will test your program with three clients.

Create another thread for the chat server that broadcasts current system time to all connected clients every 5 seconds. For example, all clients should receive a message containing current system time periodically and print it out.

How does Emotet establish connection to the C&C infrastructure?

You would like to build a classifier for an Autism early detection application. Each data point in the dataset represents a patient. Each patient is described by a set of attributes such as age, sex, ethnicity, communication and development figures, etc. You know from domain knowledge that autism is more prevalent in males than females.

If the dataset you are using to build the classifier is noisy, contains redundant attributes and missing values. If you are considering a decision tree classifier and a k-nearest neighbor classifier, explain how each of these can handle the three mentioned problems:

1. Noise

2. Missing Values

3. Redundant Attributes

I've seen this question answered for C but I don't know how to translate to Java.

Write a program that requests the hours worked in a week and the basic pay rate, and then prints the gross pay (before tax), the taxes, and the net pay (after tax).

Assume the following:

1. Basic pay rate: from user's choice
2. Overtime (in excess of 40 hours) = time and a half (i.e., if the hours worked is 45, the hours for pay will be 47.5, which is 40 + 5 * 1.5).
3. Tax rate:
   • 15% of the first $300;
   • 20% of the next $150;
   • 25% of the rest.

Apteryx, based in Queen Street, have approached you to gain some insight into their planned development of the company’s IT setup. The management wish to expand the company and as such they want to be able to connect the new satellite offices to their main office in Queen Street. The two new satellite offices will be in Otara and on Waiheke Island. But it turns out that the management knows nothing about the technology involved in connecting the new satellite office to the main office. Your task is to develop a report which will educate the management on the basics of networking.

The following must be included in your report;

a) the conceptual concepts e.g. topologies and layered models

b) using the concept of OSI and TCP/IP models compare the process a human would send a message against how a computer would do the same.

c) type of equipment they will need to purchase to achieve their goals, provide a discussion on the types of equipment.

d) the complexity involved in providing a complete solution.
