Locating and Utilising Inherent Qualities in an Expanded Sound Palette for Solo Flute

Alice Bennett(알리스 베넷),Vincent Giles(빈센트 길레스) 한국전자음악협회 2015 에밀레 Vol.13 No.-

플루트 독주 특유의 즉흥적 음악언어를 추구하면서, 전통적이고 현대적인 연주기법의 범위를 넘어 컴퓨터를 이용한 악기의 확장이라는 영역으로 넘어가야 할 필요성을 종종 느낄 때가 있다. 이러한 이유로 알리스 베넷Alice Bennett의 창작 작품은 실용적인 사운드 팔레트를 확장시키는 새로운 전자음향적 기술을 탐색케 한다. 이 글은 빈센트 길레스Vincent Giles가 실시간으로 분광 영역 마이크로사운드 증폭 소프트웨어SDMAS(Spectral Domain Microsound Amplification Software)를 사용한 플루트 연주에 관하여 기술한다. 분광 영역 마이크로사운드 증폭 소프트웨어SDMAS는 실시간으로 입력된 소리가 특정 음량 기준점 주변 배음들의 음량을 변화시켜, 작은 소리를 상대적으로 큰 음량으로 증폭시킨다. 그 결과 들을 수 없었을 [작은] 배음들이 큰 음량의 배음들과 같이 커져, 기존의 악기 혹은 변형된 악기 음색과도 확연히 다른 음색을 얻게 된다. 이는 연주자/작곡가가 순전히 어쿠스틱 악기에서 얻을 수 있는 것과 다른 음색을 보여줄 뿐 아니라 보다 넓은 영역의 음색을 활용할 수 있게 해준다. 이는 초월적 악기의 확장형태instrument configuration에 기반한, 음향적으로 풍부하고 독특한 즉흥적 음악언어를 이끌어 낼 것이다. In the search for an idiosyncratic improvisatory language of solo flute performance, it is sometimes necessary to move beyond the scope of traditional and extended techniques into the world of instrument-extension through computers. To this end, Alice Bennett’s creative work leads to the exploration of new electroacoustic techniques, searching for ways to expand the available sonic palette. This paper documents an electronically-extended flute performance utilising Vincent Giles’ Spectral Domain Microsound Amplification Software (SDMAS) in real-time. The SDMAS amplifies soft sounds relative to loud, by real-time input, shifting the partials by amplitude around an amplitude-based pivot point. The result is that these otherwise-inaudible partials increased to audibility alongside the higher amplitude partials, drastically altering the perceived timbre of the instrument or instruments being treated. This allows the performer/composer to not only discover, but to exploit a greater range of timbres than are available to a purely acoustic instrument. These explorations lead to a sonically enriched and idiosyncratic improvisatory language based on this hyper-instrument configuration.

Application of computers to Cave Surveying

Bennett, A.J. The Speleological Society 1997 Journal of the speleological society of korea Vol.5 No.2

The reduction of cave survey data is an essentially straightforward but repetitive mathematical task which can be carried out to advantage using virtually any type of computer from a programmable calculator upwards. The obvious benefits are speed and accuracy in reducing and adjusting the raw data to obtain the x,y,z coordinates (eastings, northings and elevations) of the surveyed points. Additionally, depending on the functionality of the software (program) and power of the hardware (computer), the user may be able to build up a data base of surveys, plot out on paper scaled plans and elecations of the cave and possibly even see a three-dimensional model of the cave, in perspective or some other projection, as an aid to understanding the spatial relationships of cave passages.(omitted)

The Shamrock and the Maple Leaf : Yeats and Canadian Modernist Poetry

Bennett Yu-Hsiang Fu 한국예이츠학회 2016 한국예이츠 저널 Vol.51 No.-

캐나다 시의 정원에 뿌려진 씨앗 중에서 예이츠가 1차세계대전 이후의 캐나다의 대표적 시인들과 문학운동에 미친 직간접적 영향은 무시할 수 없다. 이 논문 은 아직 예이츠 연구분야에서 잘 다루어지지 않은 예이츠의 북미 강연여행(1903-4년)의 흔적 을 찾고자 한다. 그리고 캐나다 본연의 목소리를 내고자 하는 작가들에게 캐나 다의 몇몇 도시에서 행한 예이츠의 강연이 어떤 영감을 주는 지 연구할 것이다. G.D. 로버츠와 블리스 카먼의 작품에서처럼 예이츠와 그의 작품에 대한 수많은 비유와 비 교점은 캐나다의 시에 깊이 베어있다. 시의 요람으로서 캐나다 남부와 몬트리올의 맥 길대은 캐나다의 모더니스트 시인들을 생산하는데, 스미스를 대표로 하는 맥길그룹은 A.J.M 스미스와 F.R. 스콧이 편집하는 맥길 격주 리뷰 와 같은 군소 문예지를 통해 서 캐나다의 시에 체계적인 모더니즘 운동을 소개한다. 특히 스미스는 이전의 캐나다 의 시 기법에 아일랜드의 모더니스트적 기법을 녹여서 시의 혁신을 가져온다. 스미스 자신의 작품은 시작법과 강한 어조는 쉽게 예이츠의 시를 연상시킨다. 이 논문은 예이 츠와 아일랜드 문예부흥운동이 캐나다의 모더니스트 시 운동에 미친 가닥을 찾아서 문학의 직물을 짜고자 한다. Of all the seeds breeding Canadian poetry to the literary garden, Yeats’s direct and indirect influences on representative post-WWI poets and literary movements in Canada cannot be dismissed. This essay attempts to trace Yeats’s North American lecture tours (1903-4), still quite unremarked in Yeats Studies, and to examine how these lectures in some Canadian cities inspired the writers still striving to find a national, poetic voice. As in the works of G.D. Roberts and Bliss Carman, countless allusions and deliberate references to Yeats and his work pervade the Confederation verses. The literary cradle in Lower Canada, McGill University in Montreal, produced influential Canadian modernist poets, the McGill Group with Smith as a representative, with programmatic introductions of modernism into Canadian poetry in small magazines and literary journals such as McGill Fortnightly Review, edited by A.J.M. Smith and F. R. Scott. Smith particularly infuses the previous Confederation style with Irish modernist techniques into the poetic innovation. Smith’s own work is highly reminiscent of Yeats for the Yeatsian principle of versification and fervent speeches. This essay thus aims to pick up these threads and weave onto the literary fabric the Canadian modernist verse influenced by Yeats’s work and the Irish literary renaissance.

Wireless sensor networks for underground railway applications: case studies in Prague and London

Bennett, Peter J.,Soga, Kenichi,Wassell, Ian,Fidler, Paul,Abe, Keita,Kobayashi, Yusuke,Vanicek, Martin Techno-Press 2010 Smart Structures and Systems, An International Jou Vol.6 No.5

There is increasing interest in using structural monitoring as a cost effective way of managing risks once an area of concern has been identified. However, it is challenging to deploy an effective, reliable, large-scale, long-term and real-time monitoring system in an underground railway environment (subway / metro). The use of wireless sensor technology allows for rapid deployment of a monitoring scheme and thus has significant potential benefits as the time available for access is often severely limited. This paper identifies the critical factors that should be considered in the design of a wireless sensor network, including the availability of electrical power and communications networks. Various issues facing underground deployment of wireless sensor networks will also be discussed, in particular for two field case studies involving networks deployed for structural monitoring in the Prague Metro and the London Underground. The paper describes the network design, the radio propagation, the network topology as well as the practical issues involved in deploying a wireless sensor network in these two tunnels.

MASSES AND ORBITAL CONSTRAINTS FOR THE OGLE-2006-BLG-109Lb,c JUPITER/SATURN ANALOG PLANETARY SYSTEM

Bennett, D. P.,Rhie, S. H.,Nikolaev, S.,Gaudi, B. S.,Udalski, A.,Gould, A.,Christie, G. W.,Maoz, D.,Dong, S.,McCormick, J.,Szymań,ski, M. K.,Tristram, P. J.,Macintosh, B.,Cook, K. H.,Kubiak, M.,P IOP Publishing 2010 The Astrophysical journal Vol.713 No.2

<P>We present a new analysis of the Jupiter+Saturn analog system, OGLE-2006-BLG-109Lb,c, which was the first double planet system discovered with the gravitational microlensing method. This is the only multi-planet system discovered by any method with measured masses for the star and both planets. In addition to the signatures of two planets, this event also exhibits a microlensing parallax signature and finite source effects that provide a direct measure of the masses of the star and planets, and the expected brightness of the host star is confirmed by Keck AO imaging, yielding masses of M(*) = 0.51(-0.04)(+0.05) M(circle dot), M(b) = 231 +/- 19 M(circle plus), and M(c) = 86 +/- 7 M(circle plus). The Saturn-analog planet in this system had a planetary light-curve deviation that lasted for 11 days, and as a result, the effects of the orbital motion are visible in the microlensing light curve. We find that four of the six orbital parameters are tightly constrained and that a fifth parameter, the orbital acceleration, is weakly constrained. No orbital information is available for the Jupiter-analog planet, but its presence helps to constrain the orbital motion of the Saturn-analog planet. Assuming co-planar orbits, we find an orbital eccentricity of epsilon = 0.15(-0.10) (+0.17) and an orbital inclination of i = 64 degrees(+ 4 degrees)(-7 degrees) The 95% confidence level lower limit on the inclination of i > 49 degrees implies that this planetary system can be detected and studied via radial velocity measurements using a telescope of greater than or similar to 30 m aperture.</P>

Design and characterization of a compact array of MEMS accelerometers for geotechnical instrumentation

Bennett, V.,Abdoun, T.,Shantz, T.,Jang, D.,Thevanayagam, S. Techno-Press 2009 Smart Structures and Systems, An International Jou Vol.5 No.6

The use of Micro-Electro-Mechanical Systems (MEMS) accelerometers in geotechnical instrumentation is relatively new but on the rise. This paper describes a new MEMS-based system for in situ deformation and vibration monitoring. The system has been developed in an effort to combine recent advances in the miniaturization of sensors and electronics with an established wireless infrastructure for on-line geotechnical monitoring. The concept is based on triaxial MEMS accelerometer measurements of static acceleration (angles relative to gravity) and dynamic accelerations. The dynamic acceleration sensitivity range provides signals proportional to vibration during earthquakes or construction activities. This MEMS-based in-place inclinometer system utilizes the measurements to obtain three-dimensional (3D) ground acceleration and permanent deformation profiles up to a depth of one hundred meters. Each sensor array or group of arrays can be connected to a wireless earth station to enable real-time monitoring as well as remote sensor configuration. This paper provides a technical assessment of MEMS-based in-place inclinometer systems for geotechnical instrumentation applications by reviewing the sensor characteristics and providing small- and full-scale laboratory calibration tests. A description and validation of recorded field data from an instrumented unstable slope in California is also presented.

The Feeling of Going: Judgments of Learning(JOLs) for Maps and Directions

Bennett L. Schwartz 대한사고개발학회 2006 The International Journal of Creativity & Problem Vol.16 No.2

Spatial metamemory is an unexplored topic, despite our knowledge of spatial me-mory. In the current study, Judgments of learning (JOLs) for maps (Experiment 1) and verbal directions (Experiment 2) were examined. The tasks were chosen to mirror real-world spatial learning situations. In both studies, participants studied for 60 seconds a map or a set of directions from one place to another. Following study, participants assessed JOLs on a 0 to 100 scale immediately after the map (Experiment 1) or the directions (Experiment 2) were removed. Participants then wrote or drew the directions from one place to another. These JOLs are immediate JOLs (Nelson & Dunlosky,1991), which tend to be low in accuracy (.3 to .4). For both maps and directions, the gamma correlations were above .8. Calibration of the magnitude of the judgments also closely matched performance. Various explana-tions for the strong gamma correlations are given.

Four Principles of Memory Improvement: A Guide to Improving Learning Efficiency

Bennett L. Schwartz,Lisa K. Son,Nate Kornell,Bridgied Finn 대한사고개발학회 2011 The International Journal of Creativity & Problem Vol.21 No.1

Recent advances in memory research suggest methods that can be applied to enhance educational practices. We outline four principles of memory improvement that have emerged from research: 1) process material actively, 2) practice retrieval, 3) use distributed practice, and 4) use metamemory. Our discussion of each principle describes current experimental research underlying the principle and explains how people can take advantage of the principle to improve their learning. The techniques that we suggest are designed to increase efficiency—that is, to allow a person to learn more, in the same unit of study time, than someone using less efficient memory strategies. A common thread uniting all four principles is that people learn best when they are active participants in their own learning.
