SHORT COMMUNICATIONS

We consider the important practical and theoretical problem of designing a low-cost communications network which can survive failures of certain network components. Our initial interest in this area was motivated by the need to design certain “twoconnected” survivable topologies for fiber optic communication networks of interest to the regional telephone companies. In this paper, we describe so...

Commonly used tools for overcoming the time barrier are asynchronous communication systems such as Email, mailing lists, and Netnews (collectively referred to as “E-mail” below). Asynchronous communication systems enable each participant to read messages and write replies when convenient.There is no need for all participants to be present at the same time to achieve communications. Likewise, as...

The electronic communications systems that are proliferating throughout modern society offer speed, accuracy and ever diminishing cost. They also present serious problems of security. As the ordinary transactions cond ucted in person, on the telephone or by written co�respondence have come increasingly to be conducted by new kinds of electronic systems the suscepti­ bility of organizations and ...

Background: Smartphones are popular technologies that combine telephone communications and informatics in portable devices. Limited evidence exists regarding their effectiveness in improving academic performance among medical students. This study aims to assess whether a smartphone application could improve academic performance in multiple-choice tests. Methods: A double-masked randomised trial...

Future telemedicine systems will exploit mobile communications technology so that patients who are free to move around at home or at work, or in emergency medical situations, can be monitored in a hospital. At present, the GSM mobile telephone cellular network is limited to 9.6 kbps, but with the introduction of the third generation (3G) network, data rates of 144 kbps will be available, giving...
