    A Symbolic Sonification of L-Systems

    Full text link
    This paper describes a simple technique for the sonification of branching structures in plants. The example is intended to illustrate a qualitative definition of best practices for sonification aimed at the production of musical material. Visually manifest results of tree growth are modelled and subsequently mapped to pitch, time, and amplitude. Sample results are provided in symbolic music notation

    Cross-talk: A Shared Parameter Space for Gesturally Extended Human/Machine Improvisation

    Full text link
    This paper describes Cross-talk, a piece of music and performance system for two instruments augmented with infrared motion-tracking capability, and an artificial software improviser. Cross-talk was commissioned by the Ammerman Center for Arts and Technology at Connecticut College, for the 13th Biennial Symposium on Arts and Technology. The work is part of an ongoing collaboration focused on developing integrated hardware and software performance systems to extend the timbral and expressive capabilities of traditional musical instruments and to generate musical structure in response to information retrieved from human performers in real-time. Artistic motivations and prior related work are presented here, along with a summary of the programmatic narrative behind Cross-talk and an accompanying qualitative description of the piece. Technical details are provided for important components of the work, including the Gesturally Extended Piano and the “factorOracle” software module, which is used to facilitate the system\u27s machine improvisation capability

    On Improvised Music, Computational Creativity and Human-Becoming

    Full text link
    Music improvisation is an act of human-becoming: of self-expression—an articulation of histories and memories that have molded its participants—and of exploration—a search for unimagined structures that break with the stale norms of majoritarian culture. Given that the former objective may inhibit the latter, we propose an integration of human musical improvisers and deliberately flawed creative software agents that are designed to catalyze the development of human-ratified minoritarian musical structures

    The Necessity of Clinical Legal Education in University Law Schools: A UK Perspective

    Get PDF
    This paper proposes that the expansion and subsequent unbridling of the provision of a law clinic in the sector will provide the students with the skills necessary of graduates in the increasingly corporate, commercially motivated, UK university sector. Secondly, it provides a basis for the rationale of a movement in funding bands, a study which is being undertaken by the Higher Education Funding Council for England over the proceeding three years, in consequence to the increasing costs involved to the institutions. This increase in funding, coupled with a determination from the institution and case study evidence as presented in this paper, will hopefully propel clinical legal education to the forefront of undergraduate legal studies in the UK. Clinical legal education is a method of improving the student experience and offers various advantages if integrated fully into the university administrative set up. Such views have been given rigorous academic coverage, however this paper further analyses the academic benefits passed on to the student populace, in relation to the potential advantages to UK universities

    factorOracle: an Extensible Max External for Investigating Applications of the Factor Oracle Automaton in Real-Time Music Improvisation

    Full text link
    There are several extant software systems designed to generate music in real-time using a factor oracle automaton constructed from the musical input of a human improvisor. The impetus for the design of the factorOracle external is neither a desire to supersede these systems nor introduce novel algorithms for traversing the oracle, but rather to provide a fast, canonical interface for the automaton in Cycling74’s Max and, in future iterations, the Pure Data programming environment. Technical features of the factorOracle software are introduced here

    Flocking in the Time-Dissonance Plane

    Full text link
    This paper describes a technique for the sonification of an idealized model of the flocking behavior of birds, fish, and insects. Flocking agents are represented by pitches that move through time to produce chords of variable dissonance. The objective of each agent is to move toward more consonant chord formations with other agents. The output of the sonification is intended to provide material for use in musical composition

    Elite Perceptions of Poverty: South Africa

    Get PDF
    Summaries Elite perceptions of poverty in South Africa are affected by the distinctive character of social segmentation there. The huge size of segments and the immense distances (social, economic and psychological) between elites and the poor within segments, discourages elites from assisting poor people within their segments. They look instead to government to help the poor in general. The ruling ANC elite, unlike most elites, is fully prepared to tackle poverty. But it faces a cruel choice between pursuing growth and redistribution. It seeks both, but the emphasis has been on growth – so far to little effect

    Detection of a Substantial Molecular Gas Reservoir in a brightest cluster galaxy at z = 1.7

    We report the detection of CO(2-1) emission coincident with the brightest cluster galaxy (BCG) of the high-redshift galaxy cluster SpARCS1049+56, with the Redshift Search Receiver (RSR) on the Large Millimetre Telescope (LMT). We confirm a spectroscopic redshift for the gas of z = 1.7091+/-0.0004, which is consistent with the systemic redshift of the cluster galaxies of z = 1.709. The line is well-fit by a single component Gaussian with a RSR resolution-corrected FWHM of 569+/-63 km/s. We see no evidence for multiple velocity components in the gas, as might be expected from the multiple image components seen in near-infrared imaging with the Hubble Space Telescope. We measure the integrated flux of the line to be 3.6+/-0.3 Jy km/s and, using alpha_CO = 0.8 Msun (K km s^-1 pc^2)^-1 we estimate a total molecular gas mass of 1.1+/-0.1x10^11 Msun and a M_H2/M_star ~ 0.4. This is the largest gas reservoir detected in a BCG above z > 1 to date. Given the infrared-estimated star formation rate of 860+/-130 Msun/yr, this corresponds to a gas depletion timescale of ~0.1Gyr. We discuss several possible mechanisms for depositing such a large gas reservoir to the cluster center -- e.g., a cooling flow, a major galaxy-galaxy merger or the stripping of gas from several galaxies -- but conclude that these LMT data are not sufficient to differentiate between them.Comment: accepted for publication in ApJ Letter
