The electron microprobe was used to study tooth discoloration caused by old silver amalgam fillings. Oscilloscopic displays were obtained for the distribution of tin, silver, and mercury. In addition, a linear graphic display technic on the Enhancitron was used. The oscilloscopic displays showed the migration of tin from the amalgam into the enamel and dentin as opposed to silver or mercury, or...

This paper describes an experimental system for the original generation and subsequent modification of volume models of complex physical objects, using interactive computer graphics. The models are built up from primitive volumes, e.g., cuboids, cylinders, swept sutfaces, etc., entered by a mechanical engineer interacting with a two dimensional projection of the model on a graphic display scree...

The most common types of nucleotide sequence data analyses and handling can be done more conveniently and inexpensively on microcomputers than on large time-sharing systems. We present a package of computer programs for the analysis of DNA and RNA sequence data which overcomes many of the limitations imposed by microcomputers, while offering most of the features of programs commonly available o...

To extend the scope of multivariate data visualization, the notion of comparative visualization is introduced: it allows the comparison of visualization methods by interconnecting several different graphic displays. This linking of visualizations, together with the possibility to interactively manipulate data, enable an analyst to display the same data set with a number of conceptually differen...

We proposed a simple formula to assess the statistical significance of homologous segments found in comparison of two nucleic acid sequences (Goad and Kanehisa, Nucleic Acids Res. 10, 247-263, 1982). This paper clarifies the basic assumptions of the formula and its reliability is examined by Monte Carlo calculations. The results were satisfactory for random sequences. The formula is a useful me...

Long-term health differences between men and women are studied by making use of a graphic display of mortality rates for the Netherlands. It turns out that till WW II women aged between eight and 16 and between 25 and 45 were worse off than men. After WW II, male excess mortality among young adults and among people aged 55 and over became a characteristic feature of the mortality pattern in man...

-Electricity authorities in the UAE have not been successful in developing reliable and accurate models of system peak load. In this study, we develop a time-series-based decisionsupport system that integrates data management, model base management, simulation, graphic display, and statistical analysis to provide near-optimal forecasting models. The model base includes a variety of time-series ...

We present a haptic rendering framework that allows the tactile display of coniplex virtual environments. This framework allows surface constraints, surface shading, friction, texture and other ejjects to be modeled solely by updaring the position of a representative object, the “virtual proxy.” This abstraction reduces the task of the haptic servo control loop to the minimization of the error ...

We present a method for mapping the content of a text collection. This method uses linguistic analysis to relate terms extracted from the texts and clusters them into thematic topics mapped onto a 2D space. While the graphic display of domain topics is useful for several information-driven tasks, the focus of the paper is more on the comparison of journal ranking by productivity (number of publ...

A program (TAXOKEY.EXE), requiring only a few keystrokes to use, is described as a universal taxonomic key in the identification of plant and animal species by IBM-compatible personal computers. A DOS text file serves as the database for a key that can be dichotomous or with multiple choices. TAXOKEY can optionally display colour or monochrome screen pictures to illustrate the keys. Additional ...
