Finite Element Study of Plane Wave Acoustic Phenomena in Ducts
… the finite element modeling of plane wave acoustic phenomena in ducts. The study looked into finite element factors such as shape functions, mesh refinement, and element distortion. The study concluded that the higher order shape function eight-node quadrilateral element gave considerably …

Resonant Space, Sonorous Time: The Varieties of Acoustic Phenomena in the Art of Christian Marclay
… to the ways that Marclay’s works mobilize acoustic phenomena to establish different types of spatial modalities for critical reflection. These include the material space of his sculptural installations, the visual space of his photographic installations, the social space of his …

Aural evolutions: intersections of sound with the physical space
… at an intersection between the fields of electroacoustic composition, experimental composition, and sound art. The general research context for this project is a territory that engages with sound as a physical medium, and is concerned with the representation of acoustic phenomena through sound …

A Parallel Solution-Adaptive Method for Turbulent Non-Premixed Combusting Flows
… accommodate large density variations and thermo-acoustic phenomena. A preconditioned multigrid algorithm is used to obtain the solution on highly stretched meshes in a more efficient manner. A flexible block-based hierarchical data structure is used to maintain the connectivity of the solution …

Abstractions from Spectral Sonorities
… —Pitch structures, isolated from the world of acoustic phenomena, are studied and manipulated to create colourful musical objects with an inherent inner logic. —In some instances Spectral concepts and techniques are integrated (or juxtaposed) with principles borrowed or adapted from tonal, …

Vector acoustic miss distance indication
… techniques, including photographic, radar and acoustic phenomena. Of these, acoustic means appeared to offer a cheap and simple solution to the measurement problem. The author then explored the principles and potential of Acoustic Miss Distance indication and arrived at the conclusion that such …

Numerical Investigation of Rotor-Gust Acoustic Interactions Using the OVERFLOW CFD Solver
… in community-noise certification is the aeroacoustic response of rotors to unsteady inflow conditions. This research addresses this gap by investigating the aerodynamic and acoustic behavior of a representative rotor subjected to time-harmonic inflow disturbances. By establishing a robust …

Elucide
… musical genre is characterized by a focus on the acoustic properties of sound, a concern that is typically reflected both in rich and colourful musical textures, as well as in the conceptual foundations of compositional processes. It is often the case that spectral composers will refer to computer …

Der Raum in der Psychoanalyse
… discovers, mainly unconsciously (e.g. by smell, acoustic phenomena), that his former consulting room has become foreign to him. He is no longer in his own room and soberly looks at an unattractive room in which he once experienced all the decisive periods of his life. The analysand goes through …

Elastic wave tailoring at the macro/micro/nano- scales using intentional strongly nonlinear coupling
In acoustics, wave tailoring refers to the manipulation of the propagation of waves or energy that are generated due to some form of dynamic loading. It includes real world examples ranging from impact mitigation to sensors and communication applications and is typically accomplished through the …

Strongly nonlinear dynamics and acoustics of coupled granular sonic vacua: theoretical and experimental studies
… of highly discontinuous and adaptive granular acoustic metamaterials for shock wave redirection and control are discussed. Then we focus on another class of granular acoustic metamaterials, namely, one-dimensional single or coupled granular chains embedded in elastic matrix, and present …
