linked lists

In this assignment, you will expand on the information provided in the course to answer the following questions in a 2- to 3-page paper:

What is the difference between a singly-linked list and a doubly-linked list?

  • In what situation would you use a singly-linked list over a doubly-linked list?
  • In what situation would you use a doubly-linked list over a singly-linked list?

If a node is in a linked list with N nodes, how many nodes will be traversed during a search for the node?

  • Explain the best- and worst-case search scenarios.
  • Explain why a singly-linked list defines a RemoveAfter() function, while a doubly-linked list defines a Remove() function.
  • Could a RemoveAfter() function also be defined for a doubly-linked list? Explain why or why not.
  • Could a Remove() function also be defined for a singly-linked list? Explain why or why not.

arduino code/ code+design required

Functional Requirements

You are required to recreate one of the Arduino functions.

  • You must be able to set an arbitrary delay (in milliseconds) using your own function, mimicking the behavior of delay().
  • You must be able to turn on and off an LED attached to pin 13. Each second you must toggle the state of the LED.

Technical Requirements

This section will serve as a guideline of what is necessary for the program to behave correctly.

You need to implement the following functions:

  • void delay_one_ms(): This function uses Timer0 to implement a one millisecond delay. Follow the steps below to get this function working properly:
    • Choose a prescaler for the desired delay
    • Disable the I-Flag in the SREG. Alternatively, save a copy of SREG to restore later.
    • Set the proper value in TCNT0.
    • Set Timer0 to Normal Mode.
    • Set the prescaler bits.
    • Wait until the overflow flag TOV0 is set.
    • Stop the clock.
    • Clear the TOV0 flag by setting it.
    • Restore the interrupts by setting the I-Flag in the SREG. Or load SREG from the copy you made before.
void delay_one_ms(){

  ...

}
  • void delay_generic(unsigned long ms): This function calls the delay_one_ms() function to implement a delay for an arbitrary amount of milliseconds. This function recreates the behavior of the Arduino delay() function.
void delay_generic(unsigned long ms){

  ...

  // call delay_one_ms()

  ...

}

Multilayer User Access Control

Learning Objectives and Outcomes

  • Identify what implementation method(s) can be used to incorporate multilayer access control
  • Describe and how each method benefits multilayered access control.

Assignment RequirementsRead the worksheet named “Multilayer User Access Control”(ws_multilayeraccesscontrol) and address the following:Using what you have learned about building a multilayer access control system, identify what implementation method(s) can be used and how each method benefits multilayered access control. 

Discussion question, 350 words and 2 references.

Communication and Team Decision Making

Part 1: Sharpening the Team Mind: Communication and Collective Intelligence

A.    What are some of the possible biases and points of error that may arise in team communication systems? In addition to those cited in the opening of Chapter 6, what are some other examples of how team communication problems can lead to disaster?

B.      Revisit communication failure examples in Exhibit 6-1. Identify the possible causes of communication or decision-making failure in each example, and, drawing on the information presented in the chapter, discuss  measures that might have prevented problems from arising within each team’s communication system.

Part 2: Team Decision-Making: Pitfalls and Solutions

A.    What are the key symptoms of groupthink? What problems and shortcomings can arise in the decision-making process as a result of groupthink? 

B.    Do you think that individuals or groups are better decision-makers? Justify your choice. In what situations would individuals be more effective decision-makers than groups, and in what situations would groups be better than individuals?

data science and bigdata analytics

data science and bigdata analytics  Provide a reflection of at least 500 words (or 2 pages double spaced) of how the knowledge, skills, or theories of this course have been applied, or could be applied, in a practical manner to your current work environment. If you are not currently working, share times when you have or could observe these theories and knowledge could be applied to an employment opportunity in your field of study.  

Research Paper on COSO framework

 

The COSO framework of internal controls is practiced within companies around the world. The objectives of the COSO framework are closely related to its five components. For this week’s activity, please discuss these five components of the COSO framework. Be sure to include each components’ impact on each of the COSO framework objectives. What do you feel an auditor would most be concerned with during an IT audit? Lastly, discuss suggestions for integrating COSO framework compliance into a company in which you are familiar. 

Your paper should meet the following requirements:

• Be approximately 2-4 pages in length, not including the required cover page and reference page.

• Follow APA6 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.

• Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find resources.

• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.
