Application of the Christiansen-Shelyubskii method to determine homogeneity and refractive index of industrial glasses
The Christiansen-Shelyubskii method has been applied to determine the homogeneity of both colorless and colored technical glasses. It could be confirmed that this method is sufficiently sensitive to changes by the melting process of flat, container and special glasses. The homogeneity factor, which essentially is the standard deviation of the refractive index, can be obtained with a precision of about ±5 %. The measurement simultaneously delivers the mean refractive index with high accuracy. This property possibly could be used to substitute density measurements to control the constancy of glass composition. The Christiansen-Shelyubskii method can be standardized and highly automated. About 15 samples can be measured per day. Thus it shows all features of a method to be used for industrial quality control

: This paper is describing a solution for an interactive video service in the World Wide Web. It has a look at creating an information retrieval system based on television and German video text. The service aims at presentation in the World Wide Web . The paper has a look on all components of the service. It starts with a brief look on the service as it appears to the client. The following part deals with obtaining traditional media and to process them into a format for later usage of a teleservice. In the following there are reflections on possible client concepts, especially methods to integrate real time video into Webpages. Video transmission also makes the main issues for the server and communication between client and server. After an explanation of our implementation the paper ends with some conclusions about experiences and future work. Keywords: Multimedia, Teleservices, WWW, Video, Stream-protocols 1 Introduction In the near future bandwidth of Internet-Connections will be w..
