Spatial data infrastructure is the main data base of e-government, and provides spatial data even the geospatial services guarantee for e-government decision support. The traditional spatial data infrastructure can meet e-government for spatial data visualization and query browsing needs, but the complex spatial analysis demand of disaster assessment and other professional services, spatial data infrastructure...
An automatic sleep stage determination system dealing with the sleep data contaminated by artifacts is developed, which is working on an expert knowledge-based multi-valued decision making method. The knowledge database is consisted of probability density functions of parameters for various sleep stages according to the visual inspection by a qualified clinician. The probability density functions...
This paper introduced an expert knowledge-based automatic sleep stage determination system working on statistical signal processing. The main methods included two processes. One was expert knowledge base construction, which was developed in terms of probability density functions (pdfs) of parameters for each sleep stage. Here, the visual inspection by a clinician was utilized rather than stage scoring...
