Dr Darren of Webel originally trained as a computational physicist and applied mathematician, performed research from 1988 to 1993 in radio astronomy and astrophysics, and worked as a scientific computing expert and particle accelerator physicist from 1993 to 1999, as well as working on numerous science and education projects after establishing the Webel IT Australia Scientific IT Consultancy in 2000. You can find out more about his science career at: Dr Darren Kelly's full-career Curriculum Vitae.

From Wikipedia: Computational Physics (Aug 2016):

Computational physics is the study and implementation of numerical analysis to solve problems in physics for which a quantitative theory already exists. Historically, computational physics was the first application of modern computers in science, and is now a subset of computational science.

It is sometimes regarded as a subdiscipline (or offshoot) of theoretical physics, but others consider it an intermediate branch between theoretical and experimental physics, a third way that supplements theory and experiment.


This zone features various (mostly archival and historical) science projects, many of which demonstrate applications of the model-based software engineering and systems engineering technologies promoted on this site and offered as Webel services.

Condition.pd

Condition.pd

Before sensible synthesis can occur each accelerometer Drancel must by calibrated, or "homed". This calibration value is then applied as an offset to condition the Drancel.

The homing process is a crucial principle in Drancing, as it defines a point of "silence and darkness" for the "drancing" performer, and promotes body awareness. The "homing" can take place at any accelerometer orientation (as long as the accelerometers are held still for the brief period of calibration, typically 1 second).

The signals are also scaled linearly, and then clipped to within -1..1 range.

Meters.pd.2

Meters.pd.2

Some vertical sliders and some array graphs as meters. These are deliberately not dB VUs, since I am working closely with the linearly scaled acceleration signals.

DSP.pd

DSP.pd

Switches the DSP engine on or off. If it is off you can't hear the audio synthesis. Doh !

Monitor.pd

Monitor.pd

Combines circle and strip/bar monitor visuals for two accelerometer Drancel RGBs.

MonitorWin.pd

MonitorWin.pd

Opens a GEM window for the Drancel RGB monitors.

I have tuned the size to work well on a data projector display at 1280x960 (the Mac OS X reference in the patch is irrelevant). I usually have the PureData audio synthesis control patches on the main display of a MacBook Pro, and the GEM visuals projected on a 2nd display.
