Understanding the evolution of Arctic polar climate from the protracted warmth of the middle Pliocene into the earliest glacial cycles in the Northern Hemisphere has been hindered by the lack of continuous, highly resolved Arctic time series. Evidence from Lake El'gygytgyn, in northeast (NE) Arctic Russia, shows that 3.6 to 3.4 million years ago, summer(More)
The EMvibe is an augmented vibraphone that allows for continuous control over the amplitude and spectrum of individual notes. The system uses electromagnetic actuators to induce vibrations in the vibraphone’s aluminum tone bars. The tone bars and the electromagnetic actuators are coupled via neodymium magnets affixed to each bar. The acoustic properties of(More)
The Snyderphonics Manta controller is a USB touch controller for music and video. It features 48 capacitive touch sensors, arranged in a hexagonal grid, with bi-color LEDs that are programmable from the computer. The sensors send continuous data proportional to surface area touched, and a velocitydetection algorithm has been implemented to estimate attack(More)
A simple, clinically viable technique utilizing PRESS and strong coupling properties is presented for discrimination of coupled brain metabolites. The method relies on signal variation due to alteration of inter-echo timings (PRESS asymmetry) while maintaining a constant total echo time. Spin response of singlets and weakly coupled spins is unchanged due to(More)
In this paper, we present the “Mobile Device Marching Band” (MDMB) as a new mode of musical performance with mobile computing devices. We define an MDMB to be, at its most general, any ensemble utilizing mobile computation that can travel as it performs, with the performance being independent of its location. We will discuss the affordances and limitations(More)
The El-Lamellophone (El-La) is a Lamellophone hyperinstrument incorporating electronic sensors and integrated DSP. An embedded Linux micro-computer supplants the laptop. A piezo-electric pickup is mounted to the underside of the body of the instrument for direct audio acquisition providing a robust signal with little interference. The signal is used for(More)
This paper describes a project undertaken in the Spring of 2014 that sought to create an audio-visual performance using an industrial robotic arm. Some relevant examples of previous robotic art are discussed, and the design challenges posed by the unusual situation are explored. The resulting design solutions for the sound, robotic motion, and video(More)
This paper presents the JD-1, a digital controller for analog modular synthesizers. The JD-1 features a capacitive touchsensing keyboard that responds to continuous variations in finger contact, high-accuracy polyphonic control-voltage outputs, a built-in sequencer, and digital interfaces for connection to MIDI and OSC devices. Design goals include(More)
