Acoustics of new and renovated chamber music halls in Russia

In recent years several classic halls for chamber music were renovated and a few halls of similar capacity were built in Russia. We have selected the most interesting ones and measured their acoustical parameters. Here we are presenting detailed descriptions of five halls in Moscow, Tula, Ufa and Penza in combination with the measurement data. Some of them have long reverberation time and their...

Improving Efficiency of Greenhouse Heating Systems Using Model Predictive Control

This article presents a comparison of commercial and model based predictive control strategies aimed at optimizing efficiency of classical heating systems used in greenhouse temperature control. Two kind of heating systems are considered: aerial pipes with hot water and air-fan heaters. By using simple linearized models of the system around the predefined setpoints and a generalized predictive ...

A Framework for Eliciting Emotional Speech: Capitalizing on the Actor’s Process

This paper offers an approach and a theoretical framework for eliciting emotional speech using actors. The framework is developed by connecting the goal-based model of emotion proposed by Abelson [1], the work of appraisal theorists, and an approach to the actor's technical process widely used in the professional theater and taught in modern conservatories. In doing so, we hope to address some ...

Automated generation of contrapuntal musical compositions using probabilistic logic in Derive

In this work we present an application developed in Derive 6 to compose counterpoints for a given melody (“cantus firmus”). The result is non deterministic, so different counterpoints can be generated for a fixed melody, all of them obeying classical rules of counterpoint. It is also possible that the counterpoint could not be generated, in this case, backtracking techniques have been implement...
