Environmental contours are widely used as basis for design of structures exposed to environmental loads. The basic idea the method is decouple description from structural response. This done by establishing an envelope joint extreme values representing critical conditions, such that any structure tolerating loads on this will have a failure probability smaller than prescribed value.

We present in this paper a new particle-based method for sampling and rendering several types of the nonphotorealistic feature contours on implicit surfaces: silhouette, shadow, specular shadow and suggestive contours. We introduce a curve adhesion behavior for dynamic particles that brings up the possibility to render any contour that is defined as an intersection of two implicit surfaces. In ...

The equal-loudness contours describe the frequency characteristic of sensitivity of our auditory system. A set of the equal-loudness contours based on British data measured in mid-1950 was standardized as ISO 226. However, several research results reported in mid-1980 showed that the set of equal-loudness contours in ISO 226 contained a large error. We, therefore, carried out this project to de...
