French horn embouchure: An electromyographic facial kinematic study
This study investigated embouchure-related muscle activities and related facial skin movement in trained French horn players. In relation to pitch and intensity of tone produced, amplitude of surface electromyogram (EMG) from five selected facial muscles and related facial skin kinematics were examined during preand post-attack phases. There was no difference in EMGs and facial kinematics betwe...
متن کاملSpectral Analysis of the French Horn and the Hand-in-Bell Effect
Adam Watts Department of Physics, University of Illinois at Urbana-Champaign ABSTRACT With the goal of investigating the effects of hand-in-bell playing of the French Horn, a technique was developed to quickly and accurately measure the input impedance of the instrument to determine intonation and playability of resonant modes. This technique is a continuation of previous work done by Professor...
متن کاملHorn Complements: Towards Horn-to-Horn Belief Revision
Horn-to-Horn belief revision asks for the revision of a Horn knowledge base such that the revised knowledge base is also Horn. Horn knowledge bases are important whenever one is concerned with efficiency—of computing inferences, of knowledge acquisition, etc. Horn-to-Horn belief revision could be of interest, in particular, as a component of any efficient system requiring large commonsense know...
متن کاملDefinability of Horn Revision from Horn Contraction
In the AGM framework [Alchourrón and Makinson, 1985], a revision function can be defined directly through constructions like systems of spheres, epistemic entrenchment, etc., or indirectly through a contraction operation via the Levi identity. A recent trend is to construct AGM style contraction and revision functions that operate under Horn logic. A direct construction of Horn revision is give...
متن کاملOcular horn.
The case of a horn-like hyperplasia of the caruncle of the left eye in a 3-month-old child is reported. An atavistic origin of this growth as a vestigial upper incisor is suggested from the anatomical location of the horn.
