Abstract

Les cinématiques parallèles se caractérisent par une structure à plusieurs chaînes cinématiques reliant la base à l’organe terminal. Les déplacements des moteurs sont couplés, ce qui accroît la complexité du calibrage de ces structures. Ce papier présente un système de mesure adapté à la machine-outils à cinématique parallèle Hita-PDR. Ce dispositif, composé d’un gabarit étalon et d’appareils de mesure, permet d’obtenir la position et l’orientation de l’organe terminal pour toutes les poses du volume de travail et suivant les cinq degrés de liberté de la machine. Plusieurs stratégies de calibrage adaptées à la machine Hita-PDR sont ensuite présentées et comparées.

Through-composed music

In the theory of musical form, through-composed music is a continuous, non-sectional, and non-repetitive piece of music. The term is typically used to describe songs, but can also apply to instrumental music. While most musical forms such as ternary form (ABA), rondo form (ABACABA), and sonata form (ABA') rely on repetition, through-composed music does not re-use material (ABCD). This constant introduction of new material is most noticeable in musical settings of poems, in contrast to the often used strophic form (AAA).

Musical composition

Musical composition can refer to an original piece or work of music, either vocal or instrumental, the structure of a musical piece or to the process of creating or writing a new piece of music. People who create new compositions are called composers. Composers of primarily songs are usually called songwriters; with songs, the person who writes lyrics for a song is the lyricist. In many cultures, including Western classical music, the act of composing typically includes the creation of music notation, such as a sheet music "score," which is then performed by the composer or by other musicians.
