I need to write a term paper on the topic Siemens Simatic- PCS7/WINCC (SCADA) 

 Chapter 3: Why are the original/raw data not readily usable by analytics tasks? What are the main data preprocessing steps? List and explain their importance in analytics. (300 Word )

 Chapter 4: What are the privacy issues with data mining? Do you think they are substantiated? (300 Word )

 This exercise is a simple extension of the word count demo: in the first part of the exercise, you’ll be counting bigrams, and in the second part of the exercise, you’ll be computing bigram relative frequencies. 

Part I: Count the bigrams Take the word count example and extend it to count bigrams. Bigrams are simply sequences of two consecutive words. For example, the previous sentence contains the following bigrams:  “Bigrams are”, “are simply”, “simply sequences”, “sequence of”, etc. Work with the sample collection Bible+Shakes.nouns on Blackboard. Don’t worry about doing anything fancy in terms of tokenization; it’s fine to continue using Java’s StringTokenizer. 

In order for this to run on a cluster, you will need to build a jar file. jar cf jar-file input-file(s) 

Questions to answer: 

1. How many unique bigrams are there? 

2. List the top ten most frequent bigrams and their counts. 

3. What fraction of all bigrams occurrences does the top ten bigrams account for? That is,  what is the cumulative frequency of the top ten bigrams? 

4. How many bigrams appear only once? 

Part II: From bigram counts to relative frequencies Extend your program to compute bigram relative frequencies, i.e., how likely you are to observe a word given the preceding word. The output of the code should be a table of values for F(Wn|Wn 1). Hint: to compute F(B|A), count up the number of occurrences of the bigram “A B”, and then divide by the number of occurrences of all the bigrams that start with “A”. 

Questions to answer: 

1. What are the five most frequent words following the word “light”? What is the frequency of observing each word? 

2. Same question, except for the word “contain”. 

3. If there are a total of N words in your vocabulary, then there are a total of N2 possible values for F(Wn|Wn-1)—in theory, every word can follow every other word (including itself). What fraction of these values are non-zero? In other words, what proportion of all possible events is actually observed? To give a concrete example, let’s say that following the word “happy”, you only observe 100 different words in the text collection.  Does this mean that N-100 words are never seen after “happy” (perhaps the distribution of happiness is quite limited? 

I have a Midterm due by Sunday 11:59 PM EST. The midterm involves creating visualizations in R and writing a paper about the same. Need help in creating the visualizations and writing the paper. Please find the instructions below and data will be provided as requested

     Create an Excel workbook that uses the built-in date & time functions in Excel to   answer the following questions:1. How many days have you been at Ole Miss,   since your first date of attendance? (it’s okay to “guess” on the   start date)2. What day of the week will the 8th of November occur on in   2018?3. How many “net working days” (e.g., Monday – Friday) are   there between August 1, 2018 and November 30, 2018?4. A bill that your   company received must be paid 75 days before the last day of this calendar   year.   What date will that be?   What month will that be?   What day of the month?   What day of the week?5. A   manufacturing process takes 157 hours to run. If it starts running at 12:30   p.m. on May 15, 2018, what date and time will it finish? What would the end   date/time be if it could be completed in 88 hours?       

1. Find a peer-reviewed scholarly journal article discussing blockchain technology. Complete a review of the article by writing a 2-3 page overview of the article. This will be a detailed summary of the journal article, including concepts discussed and findings. Additionally, find one other source (it does not have to be a peer-reviewed journal article) that substantiates the findings in the article you are reviewing. 
   You should use the UC library (https://www.ucumberlands.edu/library) and/or Google Scholar to find these types of articles (https://scholar.google.com/ )
   Once you find the article, you will read it and write a review of it.  This is considered a research article review.
   Your paper should meet these requirements: 
   • Be approximately three to four pages in length, not including the required cover page and reference page.
   • Follow APA 7 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.

The goal of this assessment is to give learners the opportunity to demonstrate their ability to produce a risk assessment for a Fintech company based on a given scenario.

Scenario 

Your client is a growing, Dublin-based, Fintech business with 60 staff, 40 of these employees have been recruited in 6 months. 90% of the staff are currently working from home using a mix of company and personal IT devices. The company handles sensitive databases and records as part of its typical business practice. The company is also involved with software development. The IT department handles the day-to-day data security. This will be the first formal risk assessment undertaken at the company. 

The CEO has a good understanding of cybersecurity and is eager to comply with regulations and protect the company from cyber-risks. 

As a reference point, the following website is a company similar to the one we are working with: https://www.aikido.finance/ 

Considerations
• What factors would need to be examined in a risk assessment process?
• Have we documented and assessed the assets which need to be protected?
• Which risk mitigation actions need to be considered?
• Are there data policy documents that need to be in place?
• What factors would benefit the overall cybersecurity posture of the company? 

Your Task: Provide a risk assessment report focused on identifying and mitigating risks within the organization.

 Start Access. Open the file named Exp19_Access_Ch05_Cap_Varmel_Studio_Toys.accdb. Grader has automatically added your last name to the beginning of the filename. 

 You will save the database file with a new name and create a new table that will be the source for a lookup.

Save the database file as Exp19_Access_Ch05_Cap_Varmel_Studio_Toys_LastFirst.accdb. Use Design view to create a new table. Add ItemTypeID as the first field name, with data type AutoNumber; add ItemTypeDescription as the second field name, with data type Short Text and field size 15. 

Ensure ItemTypeID is set as the primary key. Save the table and name it Item Types. Add two records: Action Figure and Poster. Close the table.

884

You will edit the Inventory table design to validate data. You will make two fields required and add a validation rule to a field. You will also make sure you test the validation to make sure the rules work as intended.

Open the Inventory table in Design view. Set the InventoryQty and ItemTypeID fields to Required.

 his week select an organization that has a Global platform (they operate in more than one country), that has demonstrated operational excellence.  In this paper, perform the following activities:

• Name the organization and briefly describe what good or service they sell and where they operate.
• Note how they are a differentiator in the market.
• Note the resources used to ensure success in their industry (remember resources are comprised of more than just people).
• Explain what actions the company took to achieve operational excellence.

The above submission should be three pages in length.  Remember the total length does not include the APA approved cover page or the references.  There should be at least three APA approved references to support your work. 

Write a query to determine the cost of the least expensive part in the part table? Format the returned price in dollars and cents using the correct function. Your result set should have only one amount in it.

 (TCO 7) Using the orders table, write a query that will list the order number, date, and customer number for every order that was made prior to September 5, 1998. Format the date in your result set to be in the same format as above (i.e., September 5, 1998).
(Points : 15)
 

(TCO 7) Write a query that will list the customer first and last name and the sales rep commission rate using JOIN ON.
