Three hierarchies of transducers

Hierarchies of String Languages Generated by Deterministic Tree Transducers

Experimental Evaluation of Three Designs of Electrodynamic Flexural Transducers

Three designs for electrodynamic flexural transducers (EDFT) for air-coupled ultrasonics are presented and compared. An all-metal housing was used for robustness, which makes the designs more suitable for industrial applications. The housing is designed such that there is a thin metal plate at the front, with a fundamental flexural vibration mode at ∼50 kHz. By using a flexural resonance mode, ...

Three Dimensions of Modern Social Governance: Markets, Hierarchies and Kinships

The paper is based on the analysis of economic and social systems in the last 80 years that ended up both in the processes of transition, and globalisation. The paper is theoretic with an illustrative material on new features of social governance, including the comparison of transition economies with advanced EU countries. Author challenges the dualistic view of social, political and economic g...

Three hierarchies of simple games parameterized by "resource" parameters

This paper contributes to the program of numerical characterization and classification of simple games outlined in the classic monograph of von Neumann and Morgenstern. We suggest three possible ways to classify simple games beyond the classes of weighted and roughly weighted games. To this end we introduce three hierarchies of games and prove some relations between their classes. We prove that...
