Application of a Smith predictor for control of fabric weight during weaving

A theory of bifurcation equivalence for forced symmetry breaking bifurcation problems is developed. We classify (O(2), 1) problems of corank 2 of low codimension and discuss examples of bifurcation problems leading to such symmetry breaking

Acoustic illuminations: recorded space as soundscape composition

Following López, I claim that although any sound can be music, not all sound is music. Soundscape composition begins when a soundscape prompts the composer to engage musically with it. How this engagement manifests is influenced by composers’ differing philosophical, practical and aesthetic positions. These are explained in Part I and provide the basis to my analysis of soundscape composition. Part II focuses on how my soundscape composition manifests (in ways prescriptive, spontaneous and retrospective), how it is explored both temporally and spatially and how the listening subject and the acoustic agent are inextricably linked. Within the developmental phases of context, field work and editing, my first compositional approach, through which my works can be identified, is defined in three ways: as hyper-real (in which particular acoustic elements are exaggerated, distorted or re-combined); as soundwalks (in which the microphone is moved through space) and as improvisational intervention (using musical instruments to acoustically illuminate the space being recorded). My second compositional approach presents the perception of sound as micro, macro and ambient. My third approach, which is at the heart of all my soundscape composition, uses the microphone as a musical instrument in its own right. In all approaches, serendipity and my own acoustic presence are embraced. Diffusion of my work is intended to engage the listener in creative contemplation of soundscapes, any other perceived agendas such as documentation being incidental
