May 2009 Meeting
A Night at the Park: Norfolk Tides vs. Rochester Red Wings Saturday, May 23, 2009 at 7:15 PM
The IEEE Hampton Roads Section is having its Summer Social at Harbor Park. The Norfolk Tides will be playing against the Rochester Red Wings in AAA baseball action. Game time is 7:15 PM. Please RSVP so that the tickets can be purchased ahead of time to ensure that our group will be seated together. IEEE members are encouraged to bring their families and/or friends.
Brain Teaser Challenge - "April"
I recently had to spend the night in the hospital. I didn't really feel that sick, but I had had some strange symptoms earlier and they wanted to do some tests to try to understand what had happened. I left the next day having had a very bad night's sleep and a huge barrage of tests. Though they were efficient and thorough, no one really knew what had caused my symptoms two days prior. I think this happens a lot in medicine. That is, they see some symptoms and they do their best to explain them. Then for all their best efforts and the latest technology, no one really knows. I feel blessed that no one suggested treating me for their best guess of what the problem might be.
In an earlier part of my career I did R&D in nuclear medicine, specifically gamma imaging. This is not taking pictures of gamma rays, but rather using gamma rays to take pictures inside of your body. Technetium-99m is a common radionuclide used in such imaging. As it turns out, most of the technetium used in medicine is harvested from a device called a cow as a by-product of another radionuclide called molybdenum-99. Our question this month is how does molybdenum-99 become technetium-99m? Hope you don't glow in the dark.

Brain Teaser Challenge - "March"
These brain teasers get printed in newsletters around the world. In some of these places English is not the first language. I don't think anyone is doing an official translation. So I sometimes wonder if those readers having to translate it for themselves have a hard time making sense of my stories and humor. To be fair I have considered sending out the column alternately in Hindi, German, Chinese, etc., so as not to show favoritism to the native English speakers. Then I remembered that I am not really fluent in all of these languages and I don't even own an English-Chinese dictionary.
Anyway, let's get to the problem. I attended a conference on weather modeling the other day, a very interesting physics and math problem domain. These calculations are sometimes done in order to predict the path of hurricanes and tornadoes. So, after a 100 pound woman is airborne, how long does it take her to get from 0 to 30 MPH if she has a constant net horizontal accelerating force from the wind of 100 pounds(force). Obviously the wind is building during her entire flight. You can ignore wind drag and all other forces for this problem. I am using English units in order to add to the challenge, maybe metric next time.

March 2009 From The Chair
Few things in this life are for certain. Unfortunately for electrical engineers, power distribution is not one of them. However we can mitigate the risk we face by having a back-up power source. So in March we will have Rob Robins of Bay Diesel come talk to us of providing back-up power systems for facilities and plants that we may have design cognizance over. This topic has a wide appeal to all of us, because I cannot think of an area of electrical engineering that is not dependent on power. So understanding the current factors of back-up power generation and understanding how those factors affect our everyday professional lives is important to us all.
I want to thank Dr. Reddy for his presentation in February on RFID technology. We learned that the airplane industry utilizes RFID tags for maintenance monitoring. While bar-coding has improved monitoring of inventory greatly, RFID tags are the next step. How many of us have stood in a grocery line while the clerk struggles to get the bar code off an item we are buying. In fact, one on my dogs has a RFID tag implanted in her, so you can say that I have a high tech wiener dog.
So far I only have one volunteer for the 5oth anniversary planning committee. I am still looking for a few more volunteers. I want to thank Dr. Ibrahim for volunteering. On a similar note, Janet Rochester has offered to represent the section at the IEEE-USA meeting in Philadelphia in August. I would like for us all to support Janet in providing a good history of the section. So if anyone has some section history, including any personal accomplishments , that they would like to share, please provide them to any officer of the section. This is good because I am thinking that we want a good historical accounting for when our section anniversary occurs in 2011. Thank you Janet .
I will be representing the section for the SoutheastCon in Atlanta this upcoming month. I will provide some feedback to the section as to what is presented at the Region 3 meeting that occurs during that time. So stay tune for additional information.
I am looking forward to meeting everyone in March.
