- Abstract
- A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

- Abstract
- Ordnung hat in unserer Alltagssprache eine Fülle von Bedeutungen. Als mathematischer Begriff ist Ordnung mit einer begrenzten Bedeutung festgelegt, die als eine Abstraktion der Beziehungen 'ist enthalten in', 'ist ein Teil von' und 'ist kleiner als' verstanden werden kann. Der mathematische Ordnungsbegriff tritt in vielen Bereichen der Mathematik und ihrer Anwendungen auf. Seine aktuelle Verwendbarkeit, wie etwa im Bereich der theoretischen Informatik, machen die mathematische Ordnungstheorie zu einem attraktiven Teilgebiet der gegenwärtigen Mathematik

- Abstract
- Examines the essential features and merits of chain indexing systems. Discusses the principles and method of construction of an A/Z subject index using the chain indexing system. Highlights the experience of Kirloskar Electric Co. in Bangalore in using such an index for document retrieval. The discussion is confined to the single entry system for a document in the classified file.
