We present a scheme and a data structure that decomposes the space into adaptive-sized cells to improve the visualization of soft objects. Soft objects are visualized through the evaluation of field functions at every point of the space. According to the proposed scheme, the affecting soft objects for a point in the space is searched through the data structure called an interval tree based on t...

The concept of non-probabilistic reliability, which is to measure the reliability in terms of the amount of uncertainty consistent with the condition of no failure, is used to establish a new model for fatigue reliability analysis. Some of the uncertain parameters of structures are expressed as interval variables instead of random variables. In numerical example, fatigue lifetime of the tenders...
