As 1969, Truax 1978, McAdams 1987). long as the sound description is based on the physics of For effective generation and manipulation of the sounding objects and not only on the characteristics of sound objects it is necessary to define models for human hearing, an integration with physics-based graphic sound synthesis, processing and composition.

Predicting the Structural Performance of Heat-Treatable Al-Alloys
Advances in physically-based and adaptive numeric modelling (ANM) have lead to a significant elevation of the role of modelling in commercial alloy development and process optimisation. Within these two categories of modelling a wide variety of techniques exists, whilst hybrid approaches, taking advantage of the benefits of the both methods, are also being developed. In this paper various ANM t...
متن کاملLearner characteristics and dialogue: recognising effective and student-adaptive tutorial strategies
In recent years, there have been significant advances in tutoring systems that engage students in rich natural language dialogue. With the goal of further understanding what makes tutorial dialogue successful, this article presents a corpus-based approach to modelling the differential effectiveness of tutorial dialogue strategies with respect to learning. We present results of a study in which ...

متن کاملA tutorial on complex sound fields for audiometric testing.
A fundamental understanding of soundfield characteristics in enclosed spaces is required in order to appreciate and predict the behavior of complex sound fields (i.e., sound fields created with at least two uncorrelated sound sources on different axes) used in auditory tests for evaluating hearing aid performance, especially speech-in-noise tasks. This article is a tutorial starting with ideali...
متن کاملCriteria for Evaluating Physical Modelling Schemes for Music Creation
The success recently encountered by physically-based modeling (or model-based approaches) for music should not mask the deep challenges that remain in this area. This article first proposes an overview of the various goals that researchers and musicians, respectively operating from scientific and end-user perspectives, may pursue. Among these goals, those recently proposed or particularly criti...
