The Electro-Acoustic Music of Frederick Lesemann

A survey of the electro-acoustic music compositions of Frederick Lesemann from 1970-2004

Correspondences and Complementarity in Visual Music

Visual music is an art form that implies intermodal connections between the senses but which has historically often failed to identify aesthetically satisfying correspondences. Artistic success does not automatically emerge in one medium when its elemental characteristics are mapped to those of an existing work from another medium. I offer examples from my own abstract animations with music, which draw upon John Whitney\u27s concept of complementarity, a more intuitive correspondence at a higher level of aesthetic qualities, that of stasis and dynamism or tension and resolution

Consonance and Dissonance in Visual Music

The concepts of consonance and dissonance broadly understood can provide structural models for creators of visual music. The application of words such as \u27harmony\u27 across both music and visual arts indicated potential correspondences not just between sensory elements such as pitch and colour but also with the manipulation of tension and resolution, anticipation and stability in visual music. Concepts of harmony have a long history in proportions of space, colour and motion as well as music that artists can now exploit with new technologies. I will offer examples from my own work as well as techniques from artists such as Oskar Fischinger and John Whitney

Digital Harmony of Sound and Light

In the late 1980s and early 1990s I was privileged to work with the computer animation pioneer John Whitney Sr. and was profoundly influenced by his ideas on how to apply musical concepts of harmony to visual arts of motion. at the time of his death in 1995, he and I were planning composition software in which an artist could apply these concepts to create harmonic patterns simultaneously in sound and animation. Though this idea was never realized beyond certain tests, I have taken this step in my subsequent work in computer-generated music and video in ways inspired by, if distinct from, Whitney\u27s early artworks. This article examines ways in which Whitney\u27s ideas can be applied to musical composition, and in particular to ways in which I have extrapolated principles from these ideas to create an artistic correspondence between abstract animation and computer music

Enhancing pressure ulcer prevention using wound dressings: what are the modes of action?

Recent clinical research has generated interest in the use of sacral wound dressings as preventive devices for patients at risk of ulceration. This study was conducted to identify the modes of action through which dressings can add to pressure ulcer prevention, for example, shear and friction force redistribution and pressure distribution. Bench testing was performed using nine commercially available dressings. The use of dressings can reduce the amplitude of shear stress and friction reaching the skin of patients at risk. They can also effectively redirect these forces to wider areas which minimises the mechanical loads upon skeletal prominences. Dressings can redistribute pressure based upon their effective Poisson ratio and larger deflection areas, providing greater load redistribution.info:eu-repo/semantics/publishedVersio

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes
