This paper describes the bubble drum set, along with several polyrhythm games and interactive music activities that have been developed to show its potential for use as an input controller. The bubble drum set combines various sizes of colorful exercise balls, held in place or suspended with conventional drum hardware and thus creating a trap kit configuration in which the spherical surfaces ca...

Random number generation (RNG) requires executive control. A novel paradigm using the eight drum pads of an electronic drum set as an input device was used to test 15 healthy subjects who engaged in random or ordered number generation (ONG). Brain potentials time-locked to the drum-beats revealed a more negative response during RNG compared to ONG which had a left frontal distribution. Source a...

The heat penetration into the solid bed of rotary drums was experimentally investigated. An indirect heated rotary drum with a diameter of D=600 mm and a length L=450 mm has been used for this purpose. Temperature profiles of the gas, the drum wall and the solid bed were measured using 16 Type K thermocouples assembled on both a rotating and a fixed rod that attached inside the drum. Hence, the...

This paper presents a novel drum transcription system for polyphonic music. The use of a band-wise harmonic/noise decomposition allows the suppression of the deterministic part of the signal, which is mainly contributed by nonrhythmic instruments. The transcription is then performed on the residual noise signal, which contains most of the rhythmic information. This signal is segmented, and the ...

Title of Document: TIN WHISKER RISK ASSESSMENT STUDIES Tong Fang, Doctor of Philosophy, 2005 Directed By: Professor Michael G. Pecht Department of Mechanical Engineering As a result of the global transition to lead (Pb)-free electronics, pure tin and high tin lead-free alloys have been widely adopted by the electronics part manufacturers as the materials of terminal finishes. However, electrica...

Objectives: Searching for testicular intraepithelial neoplasia (TIN; carcinoma in situ) in the contralateral testis of patients with germ cell tumour (GCT) may early disclose contralateral GCT. A single biopsy of the testis is thought to accurately detect TIN. Reports on false-negative biopsies have challenged this view. We investigated whether systematic two-site biopsies are more sensitive th...

A low head recirculating aquaculture system has been designed, constructed, and is being tested at the Vriginia Tech Aquaculture Lab. Each recirculating system contains two grow-out tanks; a filtration vessel containing a microscreen drum filter; and four rotating biological contactor (RBC) biofilters; sixteen airlift pumps (eight per tank); a regenerative blower with air lines, vacuum lines, a...

In this report, both p- and n-type tin oxide thin-film transistors (TFTs) were simultaneously achieved using single-step deposition of the tin oxide channel layer. The tuning of charge carrier polarity in the tin oxide channel is achieved by selectively depositing a copper oxide capping layer on top of tin oxide, which serves as an oxygen source, providing additional oxygen to form an n-type ti...
