Diversion Tunnel of a Hydroelectric Plant on Nestos River (Greece). A Case Study

A complete description of a geological and geotechnical investigation for the construction of a diversion tunnel in Platanovrisi dam area, East Macedonia, Greece is given. The numerical stress analysis and stress failure analysis results are presented, along with results of structurally controlled failure modes. The requirements for the application of the method are described. The conclusions from the application of the failure criterion, as well as the comparison between the analysis and the actual construction results have been discussed

Parallel text alignment

Parallel Text Alignment (PTA) is the automatic content alignment of multiple text documents originating or derived from the same source. Such an alignment allows for more powerful retrieval of document contents due to the addition of translation approaches to the retrieval problem. The implications of this result in improving multimedia data access in digital library applications, range from facilitating the analysis of multiple English language translations of classical texts to enabling on-demand and random comparison of multiple transcriptions derived from a given audio stream or associated with a given stream of video, audio, or images. In this paper we present an efficient algorithm for achieving such an alignment, and demonstrate its use with two applications. This result is an application of the new framework of Cross-Modal Information Retrieval recently developed at Dartmouth College and Michigan State University. © 2000 Springer-Verlag

A Medical Data Collection System for Sharing Data with Outside Collaborators

The medical field has seen a huge increase in data collection due to new technologies and techniques, particular in imaging, where large amounts of data are generated. Medical groups are now working together with computational groups to develop methods and tools to process imaging data sets quickly and efficiently. However, due to recently introduced privacy regulations, usually only “clean ” patient data can be shared
