Exploring Various Automata and Regular Expressions

 

1) For the automaton language below:
(attached in image)
a) Graph of the corresponding DFA
b) DFA State Transition Matrix.
2) For the expression for (a | bc)*(aca | bcb | cab)ccc:
Yo. The automaton graph.
ii. A(∑, Q, q0, F, ∂).
3) Write the automaton for the following language.

a) Strings must contain at least one 1001.
b) It should not have 0101.
c) If starting with 0 ends with 0.

Factors Influencing Citations and Influence of Research Papers

After reading Casadevall, & Fang, F. C. (2014). . mBio, 5(3)
Comment by answering the following:
What makes a paper have many citations (or influential)?
How much importance do you put on the popularity of the topic you write about? Explain why that is so.
Respond to the discussion promptly by Thursday at 11:59PM EST, then read a selection of your colleagues’ postings and respond to at least two classmates by Sunday at 11:59PM EST by commenting the following:

Explain why you agree or disagree with the statements of your colleague under I. above.
Explain why the statements of your colleague are justified under II. Above.

 

 

Understanding the Importance of Usability Measures in Different Systems

Question One:
Why is it important to understand tradeoffs between usability measures for various kinds of systems? Explain by describing usability motivations for Industrial systems and Life Critical systems.

Question Two:
Usability testing is a significant aspect for effective interface development. List and briefly describe any four methods of usability testing.
N.B. The question asks about methods of usability testing not tools used in usability testing (surveys are an example of tools).

Question Three:
Lets suppose that you have in charge the task of developing interfaces for an interactive system (website, mobile application, etc.).
Sketch out the main steps that you would ultimately include in your design process.

 

Crafting Effective IT Documents: Front Matter, Body Content, and Back Matter

Analyze techniques to effectively compose a major IT document after watching the videos or by conducting research by addressing the questions below:

Video: How to format a book in MS Word (Part III: Front matter, back matter and section breaks): https://www.youtube.com/watch?v=R-5kJl5rN6E
Video – Front Matter, Body & End Matter in Technical Documents: https://study.com/academy/lesson/front-matter-body-end-matter-in-technical-documents.html(This is not a mandatory video you must watch; however, there is a special offer for 7 days usage–Try it first for 7 days. Special Offer!)

Explain the purpose of front matter in a technical document and provide examples.
Explain the items found in the body of a technical document.
Explain the purpose of back (end) matter in a technical document and provide examples.

Role of access control models

 

Discuss role of access control models.
Scenario: This module described three common types of access control models: discretionary, mandatory, and role-based
Assignment: Answer the following questions.
– Introduce the reason why organizations use access control models.
– Describe the objects being protected by controlling access and how a given model uses security mechanisms and technologies to enforce the rules of the model.

Enhancing Physical Security: A Case Study

The primary defense against a majority of physical attacks are the barriers between the assets and a potential attacker walls, fences, gates, and doors. Some employ private security staff to attempt to protect their assets.
Assignment Requirements:
Analyze the physical security procedures/practices at a facility that you are familiar with. For security purposes, DO NOT name the facility in your paper.
Describe the physical controls and how they protect the organization.
