5. 5 UW CSE Videos Why CSE Videos: What takes place during a day in the life of a CSE alum working in the software industry? Why do undergraduate students, graduate students, and faculty choose computer science & engineering as their field? http://www.cs.washington.edu/WhyCSE Capstone Design Course Videos: Robot Soccer, Animation, Game Design, Computing for resource-constrained environments, Accessibility, Hardware Design, and more http://www.cs.washington.edu/info/videos/

8. 8 Theory of computation languages, grammars, and automata computational complexity and intractability –Big-Oh –polynomial vs. exponential time –P = NP? graph theory – e.g. Traveling Salesman Problem ?

9. 9 Security cryptography: study of hiding information –enigma machine –RSA encryption –steganography security problems and attacks –social engineering –viruses, worms, trojans –rootkits, key loggers CSE 484 security course –hacking assignment: hack into grades, change from 0 to 100%

10. 10 Quantum computing qubit: A particle that can store 0, 1, or any "superposition" between –a bit that can sort of be 0 and 1 at once –quantum computer: uses qubits, not bits –theoretically makes it possible to perform certain computations very quickly Example: factoring integers (why is that useful?) –actual implementation still in its infancy can add single-digit numbers; can factor 15

11. 11 Robots –toys, building cars, vacuums, surgery, search and rescue, elder care, exploration

12. 12 Graphics and vision GRAIL (Graphics and AI Lab) computer vision AI and the Turing Test

13. 13 Sensor networks Environment monitoring Military Intelligence Intelligent homes –detecting human activity through device usage / voltage (S. Patel, UW) radio freq. identification (RFID) –shopping, inventory –credit cards, toll roads, badges

14. 14 Data mining data mining: extracting patterns from large data sets –What do these two lists have in common? coughing, rash, high fever, sore throat, headache, heartburn V14GR4, cheap meds, home loans, Nigeria, lower interest rate –And what does it have to do with sorting your mail? (90% of mail is sorted automatically) http://www.usps.com/strategicplanning/cs05/chp2_009.html (2005)http://www.usps.com/strategicplanning/cs05/chp2_009.html

15. 15 Science and medicine computer science –bioinformatics: applying algorithms/stats to biological datasets –computational genomics: study genomes of cells/organisms –neurobotics: robotic brain-operated devices to assist human motor control http://neurobotics.cs.washington.edu/videos.html –assistive technologies: compress sign language videos for use on cell phones http://mobileasl.cs.washington.edu/

16. 16 The developing world UW Open Data Kit: Collect medical, environmental data on cell phones http://code.google.com/p/open-data-kit/http://code.google.com/p/open-data-kit/

17. 17 Marshrutkas in Bishkek Marshrutkas – private mini buses –Set routes –No set bus stops –No expected arrival times Users have no idea when bus will arrive –Personal safety waiting for bus –Predictability Goal: help users determine when next bus will arrive. Allows safer, more efficient system, encouraging ridership.
