A laboratory built computer system for clinical electrophysiology of vision is described to illustrate how modern technology may ease the task of handling otherwise rather complicated electronic equipment and of elaborating the data obtained. An example is given of a procedure for clinical electroretinography in which the task of the operator is virtually confined to using a single command letter, which is specified in continuously updated instructions displayed on a monitor. After the patient has left, the operator checks and if necessary corrects the automatically defined maxima of a and b waves of the electroretinogram. The print-out consists of graphs of amplitude and latency versus stimulus intensity in which the normal range is indicated. The task of the operator during an EOG measurement is confined to checking the collaboration of the patient, since the complete procedure including the elaboration of the data is automated.

## Abstract A methodology has been developed to conduct probabilistic fault tree analysis during risk assessment in chemical process industries. The methodology is based on a system involving (a) development of fault tree, (b) determination of minimum cutsets or shortest pathways leading from initi
