2 SAE 574 Objective Part of Systems Architecting & Engineering (SAE) Series Objective: “Provide System Engineers And Architects With Understanding Of The Intersection Between Network Engineering, Systems Architecting, And Systems Engineering.” Elective Course in University of Southern California’s Masters Program in Systems Architecting & Engineering Class Initiated in the Fall of 2003 About 350 Students have completed the class Student Demographics: About ½ are employed by aerospace companies About 1 out of 20 are Air Force, Navy, or Army officers Remainder are foreign students or those with more of a commercial background January 2013 SAE_574_Summary.ppt

3 SAE 574 Class Format Semester Class, 16 Weeks, One night/week
12 Weekly Lectures, 2 hours 40 minutes each 3 days off! (2 holidays, one Spring Break) 1 Final Exam week (scheduled but not used) Distance Learning Format Typically only one or two students in the TV Studio, majority of students are scattered across the US Class content webcasted for online/offline viewing Class content in PowerPoint format, hosted on Blackboard Software for student preview Blackboard Software provides for Chat or Voice Interaction online, Discussion Boards offline Simultaneous Webex for real-time interaction “Walk the Talk” about Net-Centric Concepts January 2013 SAE_574_Summary.ppt

4 SAE 574 Class Grading Two Research Papers required of each student
One in place of Midterm Exam, other for Final Exam Papers are typically 20 single-spaced pages, suitably formatted for publication in a technical journal Student materials on “How to Write Research Papers” No weekly homework, but students are encouraged to Instructor with questions, outlines, drafts, etc. Students choose research topic(s) Submit abstract for approval by Instructor Can use same topic for both papers Structured analysis for each paper Specific analyses required in each case to demonstrate student’s ability to apply the class fundamentals Paper #1: Material from first 6 Lectures Paper #2: Material from next 4 Lectures Extra credit for material from last 3 Lectures January 2013 SAE_574_Summary.ppt
