  1. Lecture 1: Introduction II EEN 112: Introduction to Electrical and Computer Engineering Professor Eric Rozier, 1/16/2013

  2. Class business and logistics • Class website http://www.performalumni.org/erozier2/een112.html

  3. A BIT OF FUN FIRST…

  4. The Grade and the Gator • Two doors containing either Gators or Grades! (Normally of course, Hurricanes eat Gators for Breakfast…) But let’spretend they’rescary… 

  5. The Grade and the Gator • You will be shown two doors, to two rooms. • Each could contain either an “A” or a gator… • It could be that both rooms contain an “A”, or that both rooms contain a gator! • You will need to reason carefully and logically to survive! • Each question, pick a door, Orange or Green, or decide not to open a door. • You score one point for picking an “A”, or for refusing to pick if both doors contain gators. • Three points available for your participation grade today • If you answer wrong, you may write a short paper describing what you did wrong, and how to find the right answer, due next class.

  6. The Grade and the Gator • Form up into groups of four • On a sheet of paper, list the first and last names of each student in the group, and pick a team name • Discuss your answers, and record them • Each group will then give their answers to the class

  7. The Grade and the GatorQ1 One of these is true… The other is false… In one of these rooms there is an “A”, and in one of these rooms there is a gator. In this room, there is an “A”, and in the other room there is a gator.

  8. The Grade and the GatorQ1 One of these is true… The other is false… A

  9. The Grade and the GatorQ2 Either both signs are false… Or both are true… A gator is in the other room… At least one of these rooms contains an “A”

  10. The Grade and the GatorQ2 Either both signs are false… Or both are true… A

  11. The Grade and the GatorQ3 Either both signs are false… Or both are true… An “A” is in the other room. Either a gator is in this room, or an “A” is in the other room.

  12. The Grade and the GatorQ3 Either both signs are false… Or both are true… A A

  13. What does this have to do with ECE?

  14. WHAT IS ECE?

  15. ECE Electrical Engineering Computer Engineering (Software Engineering) The process of analyzing, designing, and integrating the hardware and software systems needed for information processing or computation. Computer Software Engineering Computer Hardware Engineering • (Audio Engineering) • The study and design of electrical signals and electrical systems • Distribute, convert energy between various forms. • Gather, store, process, communicate, present, and display data or information Not as different as they seem

  16. Examples of things made possible by ECE DVD Players And the DVD standard Cellular phones Cellular networks and standards Electric motors And Electro magnets Power Systems Communication Systems Global positioning system And more

  17. Key industries that employ electrical and computer engineers • Aerospace • Bioengineering • Environmental engineering • Manufacturing • Semiconductors • Telecommunications • Education and Research • Energy and electric power • Transportation and automotive • Film, games, and entertainment • …

  18. Cyber-Physical Systems (CPS):Orchestrating networked computational resources with physical systems Transportation (Air traffic control at SFO) Avionics Building Systems Telecommunications Automotive Instrumentation (Soleil Synchrotron) E-Corner, Siemens Factory automation Power generation and distribution Daimler-Chrysler Military systems: Courtesy of General Electric Courtesy of Doug Schmidt Courtesy of Kuka Robotics Corp.

  19. Example: Medical Devices Emerging direction: Cell phone based medical devices for affordable healthcare e.g. “Telemicroscopy” project at Berkeley e.g. Cell-phone based blood testing device developed at UCLA

  20. CPS Example – Printing Press • High-speed, high precision • Speed: 1 inch/ms • Precision: 0.01 inch • -> Time accuracy: 10us • Open standards (Ethernet) • Synchronous, Time-Triggered • IEEE 1588 time-sync protocol • Application aspects • local (control) • distributed (coordination) • global (modes) Bosch-Rexroth

  21. Example: Toyota autonomous vehicle technology roadmap, c. 2007 Source: Toyota Web site

  22. It is important to stay current! • The future is hard to predict, and the world is changing quickly!

  23. Three generations • My mother • No running water until she was 8 • Phone was a party line, 6 families shared it • Answering machine when she was 38 • Me • Computer in the house when I was born • First access to the internet when I was 13 • First cell phone when I was 21 (analog) • You?

  24. The future is hard to predict • “Heavier-than-air machines are impossible” • Lord Kelvin, President of the British Royal Society, 1895 • “I think there is a world market for maybe five computers” • Thomas Watson, IBM Chairman, 1943 • “640K ought to be enough for anybody” • Bill Gates, Microsoft Chairman, 1981

  25. The advance of technology and progress 1895 “Heavier-than-air machines are impossible” • Lord Kelvin

  26. The advance of technology and progress 1903 (8 years later)

  27. The advance of technology and progress

  28. The advance of technology and progress 1930 (35 years later)

  29. The advance of technology and progress

  30. The advance of technology and progress 1942 (47 years later)

  31. The advance of technology and progress

  32. The advance of technology and progress 1947 (52 years later)

  33. The advance of technology and progress

  34. The advance of technology and progress 1961 (66 years later)

  35. The advance of technology and progress

  36. The advance of technology and progress 1969 (74 years later)

  37. The advance of technology and progress

  38. The advance of technology and progress Within the span of a single human life, we went from one of the world’s most respected scientists doubting heavier-than-air flight was possible… to landing on the moon.

  39. And the pace is accelerating… Moore’s Law The complexity for minimum component costs has increased at a rate of roughly a factor of two per year... Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years. That means by 1975, the number of components per integrated circuit for minimum cost will be 65,000. I believe that such a large circuit can be built on a single wafer. - Gorden E. Moore

  40. The internet of things • The State of the Digital Universe

  41. A scary and exciting thought… • The systems you will be working on when you graduate do not even exist today

  42. Professional Organizations

  43. Professional Organizations • Non-profit organizations, leading professional associations for the advancement of technology. • Student branches • IEEE: http://ewh.ieee.org/sb/miami/umcg/ • Student ACM, e-mail Alan Goldman a.goldman5@umiami.edu
