The use of algorithms for calculation and analysis of RNA secondary structures has largely been limited to mainframe computers, mainly due to the 16-bit memory restrictions imposed by MS-DOS. The program presented here, RNAdraw, moves calculations to the 32-bit Microsoft Windows environments with an intuitive user interface with extensive viewing, editing and printing possibilities. The algorit...

The high density and atomic number of hip prostheses for patients undergoing pelvic radiotherapy challenge our ability to accurately calculate dose. A new clinical dose calculation algorithm, Monte Carlo, will allow accurate calculation of the radiation transport both within and beyond hip prostheses. The aim of this research was to investigate, for both phantom and patient geometries, the capa...

For clinical decision support systems designed to help physicians make diagnostic decisions, “disease similarity” data is highly valuable in that they allow continuous recommendation of diagnostic candidates. To build such a recommendation algorithm, this paper explores a method to measure disease similarity between diseases on a simplified disease knowledge base. Our disease knowledge base com...

Ultra-wideband pulse radars are promising candidates for 3-dimensional environment measurements by autonomous robots. Estimating 3-dimensional target shapes by scanning with an omni-directional antenna is an ill-posed inverse problem. Conventional algorithms such as the synthetic aperture method or parametric algorithms have a problem in terms of their calculation times. We have clarified the e...
