Submit your responses to all three questions in a single document. There should be a single title page for the document. However, each question should have its own separate references page (a source may be reused for multiple questions). The total length of the document should be between 13 and 16 pages. Do not include the wording of the questions in your paper.

Question 1:
In 750-1000 words, identify and explain the five steps of forecasting, and then come up with an original example taken from your own professional experiences to illustrate these steps. Your response must be original. You must incorporate at least three reliable sources, both as references and corresponding in-text citations. APA format is expected.

Question 2:
In 750-1000 words, explain qualitative and quantitative forecasting, and then come up with an original example of each taken from your own professional experiences to illustrate these two forecasting types. Your response must be original. You must incorporate at least three reliable sources, both as references and corresponding in-text citations. APA format is expected.

Question 3:
In 750-1000 words, identify and explain the types of data patterns, and then come up with an original example of each (strive to make it based on your own professional experiences) to illustrate each data pattern type. Your response must be original. You must incorporate at least three reliable sources, both as references and corresponding in-text citations. APA format is expected.

 Discussion Points 1. Do some Internet research on Chevron’s use of seismic imaging technology. Briefly explain how it works and how it has helped Chevron discover new oil and gas reservoirs.  C6-7 2. Do some Internet research on security vulnerabilities associated with SCADA and digital industrial control systems. Summarize the major security concerns associated with these systems and steps than can be taken to enhance their security. 3. Discuss the pros and cons of moving enterprise-wide applications that have traditionally been supported on premises to the cloud. 4. Do some Internet research on identify management and single sign on systems. Briefly explain how these work and why they are important in business intranets and extranets. 5. Why is it increasing most important for a CIO or IT executive who oversees geographically distributed enterprise networks to be business literate?

Question 1

Describe, in your own words, what caused the accidents with Therac-25?

Question 2

Identify and describe 5 communication failures discussed in the article. For each failure, discuss what led to that failure happening and what could have been done to prevent it.

Some of these communication failures are obvious, but some are more subtle. Communications failures include any instance where somebody tried to transmit information to somebody else but couldn’t, regardless of the specifics.

It helps to remember that communication failures are often mediated through systems (i.e. we build things to communicate for us and these can fail to give our message when they should). For example, if I was trapped on a desert island and put a message in a bottle, that’s an attempt at communication. If the bottle sank 5 months later in a storm, that’s a communication failure.

READ THE ATTACHED FILE CAREFULLY BEFORE GOING FOR THIS ASSIGNMENT.

This assignment requires a knowledge of logic gates, flip-flops, counters, controlled gates and input / output. This task also require a knowledge of registers and shift-registers. Develop and submit an original logic circuit for the user interface of a 5-button MP3 player. The interface must display the volume as an 8-LED bar graph, the track number and Play/Pause indicators (one LED for each). The file must be in cdl format using CEDAR app/software.

Implement the Sieve of Eratosthenes and use it to find all prime
numbers less than or equal to one million. Use the result to
prove Goldbach’s Conjecture for all even integers between four and
one million, inclusive.

Implement a method with the following declaration:

public static void sieve(int[] array);

This function takes an integer array as its argument. The array
should be initialized to the values 1 through 1000000. The
function modifies the array so that only the prime numbers remain;
all other values are zeroed out.

This function must be written to accept an integer array of any
size. You must should output for all primes numbers between 1 and
1000000, but when I test your function it may be on an array of a
different size.

Implement a method with the following declaration:

public static void goldbach(int[] array);

This function takes the same argument as the previous method
and displays each even integer between 4 and 1000000 with two
prime numbers that add to it.

The goal here is to provide an efficient implementation. This
means no multiplication, divisioni, or modulus when determining if
a number is prime. It also means that the second method must find
two primes efficiently.

Output for your program: All prime numbers between 1 and 1000000
and all even numbers between 4 and 1000000 and the two prime
numbers that sum up to it.
