Abstract
The usefulness of computer analysis of EEG is exemplified here by using it as an instrument for fine measurement of the EEG epileptiform events. By using a PC-AT compatible microcomputer and a software package developed to record, analyse and display EEG signals, topograms and brain maps of epileptiform events are drawn. The characterisation of events in the scalp near potential epileptic focus and on the neighbouring areas is done. Studies of the origin and spreading of these epileptiform events over the location (EEG foci changing) can be correlated, with the clinical characteristics and evolution of focal epilepsy.

Abstract
This work describes a disk-resident database for Prolog which uses mechanisms similar to the ones used by the clausal database for recording and retrieving terms. It is intended to be used by applications requiring a flexibility greater than that provided by an interface to traditional database system. There is almost no restriction on the terms stored in the database and the retrieval mechanisms produces terms in the order they were recorded. To enhance the performance of the system, the database organization provides an access mechanism using hash-codes on ”key” arguments of the recorded term. The database also provides basic support for multi-user access. © Springer-Verlag Berlin Heidelberg 1989.

Abstract
The versatility of Bewley's method for the calculation of transient currents and voltages using personal computers is shown. The computer time and storage required are relatively small. SOBBE program is shown to be an efficient program for the study of transient phenomena of medium-size power system networks. Numerical results are presented.
