Conceptual Design is defined before constructive design; the used concepts are more abstract. We develop two graph based approaches, a topdown using the graph rewriting system PROGRES and a more industrially oriented approach, where we extend the CAD system ArchiCAD. In both approaches, knowledge can be defined by a knowledge engineer, in the top-down approach in the domain model graph, in the bottom-up approach in the in an XML file. The defined knowledge is used to incrementally check the sketch and to inform the architect about violations of the defined knowledge. Our goal is to discover design error as soon as possible and to support the architect to design buildings with consideration of conceptual knowledge.}, subject = {CAD}, language = {en} } @inproceedings{DigelTemizArtmannArtmannetal.2003, author = {Digel, Ilya and Temiz Artmann, Ayseg{\"u}l and Artmann, Gerhard and Nojima, H.}, title = {Plasma cluster ions (PCI) influence on microbial cells viability : [abstract]}, year = {2003}, abstract = {Recently, SHARP corporation has developed the world's first "Plasma Cluster Ions (PCI)" air purification technology, which uses plasma discharge to generate cluster ions.

This efficacy increased with the time the bacteries were exposed to PCIs. The bactericidal action has proved to be irreversible. PCIs were significantly less effective in shadowed areas.

The new plasma cluster device releases positive and negative ions into the air, which are able to decompose and deactivate harmful airborne substances by chemical reactions. Because cluster ions consist of positive and negative ions that normally exist in the natural world, they are completely harmless and safe to humans. The amount of ozone generated by cluster ions is less than 0.01 ppm, which is significantly less than the 0.05-ppm standard for industrial operations and consumer electronics. This amount, thus, has no harming effects whatsoever on the human body. But particular properties and chemical processes in PCI treatment are still under study. It has been shown that PCI in most cases show strongly pronounced irreversible killing effects in respect of airborne microflora due to free-radical induced reactions and can be considered as a potent technology to disinfect both home, medical and industrial appliances.}, subject = {Clusterion}, language = {en} } @inproceedings{DigelTemizArtmannNojimaetal.2003, author = {Digel, Ilya and Temiz Artmann, Ayseg{\"u}l and Nojima, H. and Artmann, Gerhard}, title = {Plasma-generated cluster ions' effects on indoor microflora : [abstract]}, year = {2003}, abstract = {Recently, SHARP corporation has developed the world's first "Plasma Cluster Ions® (PCI)" air purification technology, which uses plasma discharge to generate cluster ions.

Es liefert Entscheidungsgrundlagen, um diese Risiken zu begrenzen und es macht transparent, welche Risiken sinnvollerweise {\"u}ber Versicherungen abgedeckt werden sollten.

Eintrittswahrscheinlichkeiten bestimmter Risiken lassen sich durch Versicherungen nicht ver{\"a}ndern. Bei Unternehmen, die mit umfangreichen elektronischen Einrichtungen produzieren oder Dienstleistungen erbringen (und das sind heutzutage wohl die meisten), muss auch das Risiko durch Blitzeinwirkungen besondere Ber{\"u}cksichtigung finden.
