Procedural tree models have been popular in computer graphics for their ability to generate a variety of output trees from a set of input parameters and to simulate plant interaction with the environment for a realistic placement of trees in virtual scenes. However, defining such models and their parameters is a difficult task. We propose an inverse modeling approach for stochastic trees that t...

In 1994, ASHRAE began developing a guideline for measuring retrofit savings (GPC-14P). In support ofGuide­ line-14p, ASHRAE initiated RP-1050 to develop a toolkit for calculating linear, change-point linear, and multiple-linear inverse building energy models. The resulting Inverse Model­ ing Toolkit (IMT) can be usedaspart ofaprocedure to measure savings. This paper describes the numerical algo...

The principal long term goal of this project is to develop a practical, portable, nested, tidal data assimilation scheme which makes use of all available data (e.g., altimetry data, current moorings, coastal radar) to constrain barotropic and baroclinic tides (especially tidal currents) in coastal areas and shallow seas. A second long term goal is to develop more efficient methods for assimilat...
