Title – Research Seminar: Collection and Comparison of different Companion Systems
Subject – Engineering
Level – University (Master of Science)
1. Cognitive Systems or Intelligent Systems – Read as many papers as possible, look into publications, projects, etc for how many systems are there ?
2. Human Robotic Systems (Types, Comparisons)
– it is related to Man-Machine-Communication (MMC) but there is a thin line differentiating both cognitive systems & MMC.
– collection of companions of human robotic system
3. Study about Cognitive Probability and how it is related to this topic.
4. Study about Virtual Agents and how it is related to this topic.
5. The SASO4 Domain in one system – check this paper (Provided) ‘Incremental Dialogue Understanding and Feedback for Multiparty, Multimodal Conversation’ (David Traum, 2012)
6. Also works of David Traum, Candace Sidner, Stefan Scherer and other relevant authors.
7. Papers of ICT (Institute for Creative Technologies), IVA conference and Utah Scenario(s).
8. They are total minimum 3-4 or maximum 10-15 systems or more – i.e., collection of companions
9. Compare the systems based on, like, their functions, limitations, etc – i.e., comparison of companions.
10. Idea of comparing technical & virtual systems is more in a way of companions (that is, with respect to ‘companions’) e.g. robots – reliable, trustworthy, etc are properties of robots.
11. Cognitive systems is more like a boss, whereas companions are more like a servants/butler, so the task is the comparison of such companions like:
– how to use and implement.
– relation to man machine interaction.
– cognitive tasks into the interaction field.

The course Paper will cover a fictitious component part known as a Hydraulic Cylinder Assembly “End Block” on the path from being released to
Purchasing as a BUY part to select, evaluate and decide on the source of supply for the company.
The company requires you to have the part made to print and in inventory at our factory in 100 days at production volumes. A timeline of activities is necessary for you to be able to track progress against and ensure that the correct processes are followed by you and the Supplier. You will categorize this part, find possible sources of supply in Juarez Mexico evaluate the suppliers you find, submit the specifications and take a bid. You will evaluate the bid, negotiate the price, establish quality standards, pilot build the part and submit samples to the internal quality group for confirmation. Then you may award the business and start production and determine the mode of transportation, ensure regulatory compliance with import and have inventory in place by day 95 of the 100 day task.
The Estimated usage for this part is 20,000 units per year. Cost Management has given you a budgeted target price based upon known elements of steel type and price per pound, the perceived standard Machine shop processes and tolerance’s and Clear Zinc Plating process, typical machinery, labor and profit totaling a purchase price of $9.75 USD each. This spend is worth $195,000. Your approval level is $50,000 requiring you to present your sourcing decision to the Vice President of Procurement in order to place the business. You must present a case to the Vice President that supports your decision to work with a given supplier and why.

// Problem Description
‘// You are working as an Engineer for a materials manufacturing research lab and have been asked
to provide an automated solution to analyse data.
‘// The data relates to a new material being developed. The data is a measure of strength recorded
every 100mm of the material and is stored in a file.
‘// Each line in the file represents a row of measurements on the material. Data is separated by a
‘// Determine the final-value for each row and column of the data.
‘// Create and display a final-value map that represents the value for each row and column as
‘// If the value for a cell in each row is less than the average for the row and column, display -1
‘// If the value for a cell in each row is greater than the average for the row and column display 1,
otherwise display 0
‘// Calculate and display the count for the values 1, 0 and -1 for each row and column
‘// Test the sheet using the following rules to determine if the sheet is rejected or accepted.
‘// Rule 1. If any count for a row or column is greater or equal to than 50% of the number of rows or
columns then that row or column is rejected.
‘// Report the number of times the patterns are detected.
‘// Where 50 or more of the patterns are identified the sheet of material is rejected.
‘// Otherwise the sheet is accepted.
‘// The manufacturing process samples 1 of every 10 sheets produced, therefore the analysis will be
undertaken as required and must be completed
‘// in a timely manner to enable the process to be stopped, recalculated, then restarted.
