Create a function to scan all of the patient's social security numbers and detect if any of them are
invalid.
A Social Security Number (SSN) consists of nine digits, commonly written as three fields separated by
hyphens: AAA-GG-SSSS. The first three-digit field is called the "area number". The central, two-digit field
is called the "group number". The final, four-digit field is called the "serial number". Any SSN conforming
to one of the following criteria is an invalid number:

Any field all zeroes (no field of zeroes is ever assigned).
First three digits above 740
If you detect an invalid social security number, print the patient's name, their social security number,
and then either "area number", "group number", or "serial number" to indicate where the problem with
the social security number was detected.

QUESTION 1

a) It is now known the average rate of infection from the spread of corona virus endemic in a certain city daily is 2. Assume a suitable distribution to model the process.

b) Write a matlab program for model the probability of infection for the next 15 days.

c) Run as simulated plot for the Probability distribution and Cumulative distribution from the program above.

d) Using Simulation model estimate the probability that 3 people will infected in the next two days.

QUESTION 2

a) i) Based on a graph of the probability distribution (Q1d) indicate the probability that 3 persons will contract the virus in a given day

ii) Find the mean and standard deviation of the number of infections from (Q1) in the past three days.

b) The recent global climate change has necessitated the need for a new model for predicting weather patterns. Two scientists who were modeling this process in Ghana ended up with two different system models.

i) What could be the possible reason(s) for the differences in their system model? Justify your answer.

ii) In relation to real world data from the process how can you select the best model to employ for subsequent simulations and prediction of the process?

QUESTION 3

We wish to model the blood type of a person. It is known that blood type is inherited. If both parents carry genes for the AS and AS blood types, each child has probability 0.3 of getting two S genes and so of having blood type SS. Different children inherit independently of each other.

a) Write a Matlab program to determine the probability that the first child these parents have with type SS blood is their fifth child.

b) In relation to the three classifications of mathematical models, discuss the given genetic modelling problem in 2(a).

c) The administration of the Kasoa Government hospital wants to improve its quality of service by reducing the waiting time of travelers. For that purpose, they want to design what could be the best queuing strategy to have the minimum waiting time. You have been task to advice on the best queuing strategy in order to reduce the waiting time of patients before attended to. Discuss how you will address the problem

Where can Radio Frequency Identification (RFID) be used? Explain the two types of RFID, and what is the main issue associated with it?

Write shell script code that displays the process tree on a Linux machine. The process tree should show the process identifier of each process. Those processes that have the same ancestor should be sorted by process identifier instead of by name. The process tree should show the full names of all threads, if any and available. Whenever the user identifier associated with a process differs from the user identifier associated with the parent of that process, the process tree should show the transition.

#!/bin/bash

echo -e "Launch utilities:\n 1. Process Tree\n 2. Process States\n 3. Threads\n"

   echo -e "\n"

   #identify a command that displays the tree of processes in Linux
#identify the options of the command you have found that meet the requirements described in section "Process Tree" of the description of Homework 03
#put the command here, followed by the options. For example, if the command is called displayprocesstree, and the options are -a, -b, and -c, the command would appear as follows:
# displayprocesstree -abc

A wireless network has a loosely defined boundary as described in the lecture slides. Describe the security issues of such a network boundary. For at least one of the security issues, describe why CIA will not be able to solve the issue, and briefly describe a method which may be used as a solution.

Write shell script code that shows all threads created by a given process. The user will provide the process identifier of that process.

#!/bin/bash

Write a C program to create a series of processes, as shown below in the diagram.

P - ------------------ > c1 ------------>c3

   |                                          |

   |------------------> c2 |----- >c4

In other words, the parent process p creates processes c1 and c2, c1 creates c3 and c4.

Write shell script code that displays a list of all active processes in the system. Lift the BSD-style “only yourself” restriction. The output should show the status of the processes.

#!/bin/bash

read -p "Enter selection [1-3], or type x to exit: " REPLY
