These results can also serve as a model and guide for the broader use ofthese techniques in other ASHRAEpublica tions. In this paper, we present a set of enhancements to the ASHRAE Handbook that demonstrate the effectiveness of multimedia and advanced presentation techniques, such as three-dimensional computer graphics, visualization, and animation techniques. This demonstration is also meant to serve as a model and guide for the broader use ofthese tech niques in other ASHRAEpublications. The enhanced chapter is intended to be used in the CD-ROM version of the Hand book, which is also posted onASHRAE'sweb site, andcan be used in other ways to promote the effectiveness of improved presentation techniques and the value of ASHRAE informa tion resources.

In this method, a common speech synthesis method (linear prediction) is adapted to pro-vide simple and accurate phoneme recognition. The recognized phonemes are then associated with mouth positions to provide keyframes for computer animation of speech using a parametric model of the human face. The linear prediction software, once implemented, can also be used for speech resynthesis. The synthesis retains intelligibil-ity and natural speech rhythm while achieving a "synthetic realism " consistent with computer animation. Speech syn-thesis also enables certain useful manipulations for the purpose of computer character animation.

To demonstrate this approach, an interactive procedural model of the lower hull timbers of a sixteenth-century European merchant ship was developed through a process of prototype implementation, and an evaluation of the usefulness and effectiveness of the prototypes developed was carried out using the timbers from the hull remains of the Belinho 1 shipwreck, found in Portugal in 2014. The 3D model was created using Houdini, a procedural node-based 3D software package. A basic collection of the main timber components of a ship’s lower hull was defined, and functional rules were created for each timber, based on real-world ship design and construction processes. Then the rules were incorporated into the logic of the procedural modelling algorithm, and the resulting model was changed by using the Belinho 1 shipwreck scantlings. The results, w...

To simulate emotional expressions in an interactive environment, an intelligent agent needs both an adaptive model for generating believable responses, and a visualization model for mapping emotions into facial expressions. Recent advances in intelligent agents and in facial modeling have produced effective algorithms for these tasks independently. We describe a method for integrating these algorithms to create an ...
