Comparison Of Radiated Power From Structurally Different Violins, Lily M. Wang, Courtney B. Burroughs
Comparison Of Radiated Power From Structurally Different Violins, Lily M. Wang, Courtney B. Burroughs
Durham School of Architectural Engineering and Construction: Faculty Publications
The acoustic power has been determined from intensity measurements on three structurally different violins: a Scherl and Roth student violin, Hutchins' SUS29S, and Hutchins' mezzo violin SUS 100. While each violin was bowed with an open-frame mechanical bowing machine, the intensity measurements were made by scanning each side of the bowing machine with an intensity probe. One-third octave band sound power levels of the acoustic radiation from each of the three instruments as each of the four open strings is bowed show that the structurally different mezzo violin produces greater power at low frequencies when the lowest (G) string is …

Architecture Program: Faculty Scholarly and Creative Activity
Inigo Jones's interpretation that Stonehenge was a Roman temple of Coelum, the god of the heavens, was published in 1655, three years after his death, in The most notable Antiquity of Great Britain, vulgarly called Stone-Heng, on Salisbury Plain, Restored. King James I demanded an interpretation in 1620. The task most reasonably fell in the realm of Surveyor of the King's Works, which Jones had been for the preceding five years. According to John Webb, Jones's assistant since 1628 and executor of Jones's will, it was Webb who wrote the book based on Jones's "few indigested" notes, on the recommendation …
Variable Speed Drive (Vsd) Applications In Dual-Duct Constant Volume Systems, Ik-Seong Joo, Mingsheng Liu, Kirk Conger, Gang Wang
Variable Speed Drive (Vsd) Applications In Dual-Duct Constant Volume Systems, Ik-Seong Joo, Mingsheng Liu, Kirk Conger, Gang Wang
Durham School of Architectural Engineering and Construction: Faculty Publications
Models have been developed for static pressure and potential supply fan energy savings by using variable speed drive (VSD) in dual-duct constant volume systems. Experiments have been performed using a full size dual-duct constant volume system installed in a 68,000 ft2 (6,317 m2) office and classroom building. The measured static pressure variations and the energy savings agree with the model projected values. The VSD saves the fan power by as much as 35%, reduces the total airflow by 15%, and decreases the excessive static pressure on the terminal box dampers. This paper presents the systems models, the …
