CALENDAR OF EVENTS Fall Picnic DISTINGUISHED LECTURE TOUR - Dr. John Proakis Utah Computer Society Chapter October Meeting Section Officer Elections NEWSLETTER LISTSERV CALENDAR OF EVENTS* SEPTEMBER 14TH - PICNIC SEPTEMBER 19TH - DR. JOHN PROAKIS, IEEE DISTINGUISHED LECTURER SEPTEMBER - SECTION OFFICER ELECTION OCTOBER - IOMEGA Fall Picnic Saturday, September 14th, 2002 Lunch: 12:30 Highland Glen Park Highland, UT Come enjoy a great (nearly free) lunch, and visit with fellow IEEE members/families while the kids play in the park. Take advantage of the location/time/drive to do something you've long thought you should do some day - visit the famous and fabulous Timpanogos Cave (you'll be glad you did)! Highland city is located in northern Utah county. Driving directions will be provided with reservation confirmation. Cost for IEEE members and families/partners (subsidized by the section): · $1 each for youngsters (12 and younger) · $2 each (13 and older) (Pay at the picnic with cash, or check to "IEEE Utah Section") RSVP to: Rusty Scott at rustys@ieee.org (if no email, call (801)974-3625). Include IEEE member #, and number of persons (by age group). RSVP deadline: 12:00 noon on Thursday 12 Sep. Menu (catered by Wallaby's Fresh Grill): · Choice of meat: Smoked Beef or Pulled Pork. · Drink. · Garden salad with Ranch dressing. · Seasoned rice. · Smashers (mashed potatoes, cheese, seasoning). · Roll/butter. · Dessert. Last year we held our first Fall picnic in Roy, adjacent to the Air Museum at Hill AFB. The picnic was well attended, and despite the fact that the museum was closed (due to security restrictions after 9/11), we got a lot of positive feedback from those who came. Based on that experience, we decided to have a Fall picnic again this year, but at a different location, to make it more accessible to a different group of members. Our original idea was to have the picnic near, and arrange for a group tour of, Timpanogos Cave. But we ran into some snags: Timpanogos doesn't have a reservable picnic area, they don't offer group tour discounts, and tour groups are limited to 20 people. We decided that the logistics of trying to coordinate ticket reservations for everyone would be excessively difficult. But not willing to completely abandon the original idea, we decided to hold the picnic in close proximity to Timpanogos, and provide information so that those who wish to can get their own tickets and tour the cave before or after lunch. [If you do go to the cave, be SURE to allow enough time for transit and hiking between locations! Tour (Visitor Center departure) times before 8:30 or after 1:30 are your best bets.] Whether or not you choose to go to the cave, there is a nice play area for the kids at the picnic park. Boating, floating, and fishing can be done in the pond. (For park info, see http://www.wildlife.utah.gov/utahco.htm#anchor-highlan-39703) Timpanogos Cave information: http://www.nps.gov/tica/index.htm (read the "TRAVEL BASICS", "ACTIVITIES", "FACILITIES" and "FEES/PERMITS" pages). Visitor Center phone: 801-756-5238. On Sep 14, the Timpanogos Cave tours run every 10 - 30 minutes between 8:00am and 3:30pm (approximate Visitor Center departure time - allow for hiking time!) The cave tour itself takes about 1 hour. The hike from the Visitor Center to the cave entrance is 1.5 miles with a 1065 ft rise. It's considered a strenuous hike (1.0 - 1.5 hours, each way). Suitable walking shoes, water, and a jacket (45 °F in the cave) are recommended. Tickets can be purchased in advance (which is highly recommended) for $6, $5, or $3 per person, depending on age. The fee to drive into the canyon is $3 per vehicle. From the picnic park to the Timpanogos Visitor Center is approximately 4 miles. The Signal Processing and Communications Society Chapter of the IEEE Utah Section is honored to host John G. Proakis as part of the Distinguished Lecture Tour Dr. Proakis will be speaking on Iterative Equalization and Decoding Date: 19 September 2002 Time: 6:30 - 7:00 PM, hors d'oeuvres 7:00 - 8:00 PM, Talk Place: Hilton Salt Lake City Center 255 South West Temple Admission: $5.00 for IEEE Members and students $10.00 for non-IEEE Members $5.00 for full time students* RSVP: Michael Rice (mdr@ee.byu.edu) by 11 Sept 2002. Abstract This talk considers iterative channel equalization and decoding, also called turbo equalization, for combating intersymbol interference in time- dispersive channels. Two equalizer structures are considered. One is the optimum channel equalizer based on the maximum a posteriori (MAP) criterion. The other is a decision-feedback equalizer (DFE). The concatenation of each of these equalizers with the decoder allows us to make multiple passes through a block of data, where in each pass, the decoder feeds back to the equalizer soft-output information on each transmitted symbol. This information is used by the equalizer (as a priori information in the case of the MAP equalizer) in processing the block of data in each pass. Experimental results are given for underwater acoustic transmission to illustrate the benefits of iterative equalization and decoding in underwater acoustic channels. * There is no charge for students who are members of either the Communications Society or the Signal Processing Society. About John Proakis Dr. Proakis received the BSEE from the University of Cincinnati in 1959, the MSEE from MIT in 1961 and the Ph.D. from Harvard University in 1967. He is an Adjunct Professor at the University of California at San Diego and a Professor Emeritus at Northeastern University. He was a faculty member at Northeastern University from 1969 through 1998. He is active in research in the areas of digital communications and digital signal processing and is the author of the book Digital Communications (New York: McGraw-Hill) and co-author of the books, Introduction to Digital Signal Processing (New York: Macmillan); Digital Signal Processing Laboratory (Englewood Cliffs: Prentice Hall, 1991); Advanced Digital Signal Processing (New York: Macmillan, 1992); Algorithms for Statistical Signal Processing (Englewood Cliffs: Prentice Hall, 2002); Discrete-Time Processing of Speech Signals (New York: Macmillan, 1992, IEEE Press, 2000); Communication Systems Engineering, (Englewood Cliffs: Prentice Hall, 1994,first edition, 2002, second edition); Digital Signal Processing Using MATLAB V.4 (Boston: Brooks/Cole-Thomson Learning, 1997, 2000); Contemporary Communication Systems Using MATLAB (Boston: Brooks/Cole-Thomson Learning, 1998, 2000). Dr. Proakis is a Fellow of the IEEE. He holds five patents and has published over 150 papers. Utah Computer Society Chapter October Meeting Security for XML and SOAP Messages The October meeting will cover the basics of what message security entails in terms of cryptographic enhancements, how it's done for XML, how SOAP is related to XML and how the security applies to SOAP messages. The presentation will be about an hour with questions afterward. The date and place have not been determined yet. We had our first meeting in July and had 21 people show up. We are planning for this meeting in Utah County. For more information, contact Russell Hunter, at rhunter@microsoft.com. Section Officer Elections Elections for the Utah Section officers will take place in September due to delays in generation of the ballot material. Please follow the directions that accompany the ballot and return your votes ASAP. We would like to thank all that have been involved in the election process, both those that are running for office and those serving on the election committee. Newsletter Listserv We have set up a listserv with IEEE to distribute information about upcoming events. Once you subscribe to this list, you will receive the newsletter via e-mail (you can unsubscribe at any time by using "unsubscribe" instead of "subscribe" the example below). To subscribe, the directions are as follows: Send an e-mail to majordomo@majordomo.ieee.org with the following in the body of the message: subscribe utah-section <your email address> You will also continue to receive the newsletter by regular mail. This list will also be used to inform members of short notice upcoming events and other IEEE correspondence that has traditionally just been posted on our web site.
