AbstractThe methodology, used in the Modular ECG Analysis System (MEANS) is described. MEANS consists of modules for signal analysis and diagnostic classification. The basic structure of the modular interpretation system remained intact over a period of 20 years, while all modules underwent many changes as a function of experience and insight, and the continuously changing information technology. The article describes the advantages of a modular approach to decision-support systems, the most important ones being easier maintenance of the software package and separate optimization and testing of each module. The overall evaluation of MEANS was done in the CSE study. Evaluation results for modules and for the entire system are presented.

This study focuses on the development of transducers for Osstell® Mentor in measuring stability of various implant systems. Experiments are performed to verify the compatibility of a self-made transducer. An acoustic signal analysis system is introduced to analyze the acoustic signal emitted from the Osstell® Mentor probe, and the frequency with peak amplitude in the amplitude-frequency plot is identified. The resonance frequency obtained is found to be linearly dependent upon the ISQ value by Osstell® Mentor. This finding is helpful for developing compatible transducers for various implant systems.

The present paper deals with the recalculation of hydraulic machinery bladings. By combining numerical tools for the geometrical description of the bladings, mesh generation, different CFD flow models (Q3D Euler, 3D Euler, Navier-Stokes) and post-processing a highly efficient integrated flow analysis system is obtained.The capability of the developed software package is shown by recalculating water turbine runners of different specific speeds, a semi-axial and a radial centrifugal impeller. The results of the flow computations are compared to each other and to existing measurements.

Abstract Effectiveness is promoted as an essential feature of a centrifugal compressor aerodynamic design and analysis system. Effectiveness measures the system’s ability to apply sound technology to the wide range of functions the centrifugal compressor engineer needs to perform to develop, apply and maintain these complex machines. Effectiveness compliments efficiency (or productivity) in the overall evaluation of a design and analysis system. This paper discusses several features that an effective aerodynamic design and analysis system should have to support the design and application of industrial process centrifugal compressors. These features are known to be occasionally (if not often) neglected. Yet they all can be incorporated using technology available from the open literature.
