✦ Synopsis

A methodology for integrating observational data of specific human errors with theoretical task analysis of the man-machine interface is presented. Error data collected during sessions using_ ~ emi-inter :tive statistics package are superimposed on a Command Language Grammar [a task analysis developed by ]. The match/mismatch between user's goals and the implementation requirements of the computer system at various levels of analysis are described. The mismatch boundaries are discussed, and recommendations are derived for the interface and the methodological approach.

## Abstract In the present paper we first introduce the Hertz vector potential and examine how the specific case of electromagnetic field diffusion problems can be formulated in terms of this potential. Its connection to other commonly used potentials is presented and a basic approach in the form o
