Purpose – The purpose of this paper is to explore the effect of e-mail interruptions on tasks and to explore the concept of e-mail addiction within the workplace. Design/methodology/approach – Data were collected from a large car rental company in the UK. The first collection method involved observing the effects of simulated e-mail interruptions on seven employees by measuring the interrupt ha...

FTP currently provides two commands for handling mail. The MAIL command allows a user to send mail via the TELNET connection (the server collects the mail and determines its end by searching for the character sequence "CRLF.CRLF"). The MLFL (mail file) command allows a user to send mail via the data connection (requires a user-FTP to handle the command but transfer is more efficient as server n...

We analyze a second order, linear, elliptic PDE with mixed boundary conditions. This problem arose as a limiting case of a Markovmodulated queueing model for data handling switches in communications networks. We use singular perturbation methods to analyze the problem. In particular we use the ray method to solve the PDE in the e-mail: [email protected] e-mail: [email protected]
