The transformer that provides electricity to the AMS building in Providence went down on Sunday, April 22. The restoration of our email, website, AMS Bookstore and other systems is almost complete. We are currently running on a generator but overnight a new transformer should be hooked up and (fingers crossed) we should be fine by 8:00 (EDT) Wednesday morning. This issue has affected selected phones, which should be repaired by the end of today. No email was lost, although the accumulated messages are only just now being delivered so you should expect some delay.
Thanks for your patience.
"Science on the Case," by Larry Stevens. Popular Science, October 2002.
Stevens covers how "new databases and digital techniques are broadeningthe kinds of evidence available to the crime scene investigator." Thesection entitled 'Pixel by Pixel' is on a digital image processingtechnique in which "the tiny dots known as pixels are converted intonumbers that represent the brightness of each dot. Software thenunleashes algorithms to search for 'noise' and remove it or increasecontrast at those spots in the tape." This digital technique is beingused to help clarify videotapes to identify individuals such as robbersin banks and stores and child-abductors in shopping malls.
