This study suggests a query conversion method based on TMDR(Topic Maps MetaData Registry) which solves heterogeneity problem distributed in networks and integrates data efficiently. TMDR is a repository which combines Topic Maps with MSO(Meta Schema Ontology). TMDR provides an integrated knowledge for solving the problem of collision between schema and(More)
Cadmium Zinc Telluride (CZT) and Cadmium Telluride (CdTe) detectors with 200µm pixellated electrodes were tested with the aim to determine material properties and electrical parameters for Hybrid Pixel Detector (HPD) systems. A 32 channel discrete analogue preamplifier platform was designed and manufactured in which radiation tests were performed on(More)
