Including Parameter Uncertainty in an Intercomparison of Physically-Based Snow Models

Northern Hemisphere spring snow cover variability and change over 1922–2010 including an assessment of uncertainty

An update is provided of Northern Hemisphere (NH) spring (March, April) snow cover extent (SCE) over the 1922–2010 period incorporating the new climate data record (CDR) version of the NOAA weekly SCE dataset, with annual 95% confidence intervals estimated from regression analysis and intercomparison of multiple datasets. The uncertainty analysis indicates a 95% confidence interval in NH spring...

Physically-based forehead animation including wrinkles

Physically-based animation techniques enable more realistic and accurate animation to be created. We present a fully physically-based approach for efficiently producing realisticlooking, natural animations of facial movement, including animation of expressive wrinkles. This involves simulation of detailed models using a GPU-based total Lagrangian explicit dynamic finite element (TLED FE) system...

Physically Based Deformable Models in Computer Graphics

Physically based deformable models have been widely embraced by the Computer Graphics community. Many problems outlined in a previous survey by Gibson and Mirtich [GM97] have been addressed, thereby making these models interesting and useful for both offline and real-time applications, such as motion pictures and video games. In this paper, we present the most significant contributions of the p...

79: Assessing Uncertainty Propagation Through Physically based Models of Soil Water Flow and Solute Transport

Soil hydrological models are inherently imperfect because they abstract and simplify “real” hydrological patterns and processes. Indeed, an important aim of modeling is to establish the simplest description possible for adequately addressing a particular problem. Also, models are frequently based on input data that are known to be inadequate for some practical purpose. Thus, uncertainties in mo...
