Meeting the diverse delay requirements of next-generation wireless communication networks is one of the most critical goals of wireless system design. Though the delay of point-to-point communications has been well investigated using classical queueing theory, the delay of multi-point to multi-point communications has not been explored in depth. The main technical difficulty lies in the interac...

Many computer viruses spread via electronic mail, making use of computer users' email address books as a source for email addresses of new victims. These address books form a directed social network of connections between individuals over which the virus spreads. Here we investigate empirically the structure of this network using data drawn from a large computer installation, and discuss the im...

The PASSWORD project provided a pilot secure electronic mail service across Europe. This paper describes some of the lessons we learned.

The Smithsonian Institution Archives (SIA) and the Rockefeller Archive Center (RAC) conducted a three-year pilot that explored preservation challenges with email collections. This paper reviews the acquisition model and workflow used based on the OAIS Reference Model. Rather than focusing on individual messages, the Collaborative Electronic Records Project (CERP) settled on preserving an accoun...

Missed appointments reduce the quality, safety and efficiency of healthcare delivery. 'No-Shows' (NS) have been identified as a problem within the rheumatology clinic at Sunnybrook Health Sciences Center in Toronto, Ontario. NS were studied through a prospective chart review and telephone interviews. Over 6 months, 110 NS took place (rate 2.5-6.8%). From interviews, 85% of NS were attributed to...

In November 1994 we (members of the former Human Cognition Research Laboratory) ran an experimental version of the Masters level course DM863, ‘Common Lisp for Artificial Intelligence,’ taught as far as possible entirely through the Internet. This report describes this course and outlines some of the experiences and ideas that evolved during this course. Introduction The intention behind this c...
