Development of the wave theory in the first half of the 19th Century is described to deal with optical problems at the early stage. Following explanations of electric charges and forces, field concepts are introduced in connection with electrons, _currents, potential differences, Oersted's discovery, Ampere's work, and moving charges in magnetic fields. Faraday's lines of forceare used to analyze electromagnetic induction and its applicationsas well as modern civilization under the influence of scientific discoveries. Further discussions of field theoriesare made for electromagnetic radiation, taking into account Maxwell's theories, Hertz's experiment, cave propagation, electromagnetic spectra, and .ether concept. Historical developments are stressed in the overall explanation. Problems with their answers are provided in two categories: study guide and end of section questions. Also included are related illustrations for explanation pur7oses and a chart of renowned people's life spans between 170E and 1900.

The essence of the project being to reveal the compositional applications of a selection of Persian, Indonesian, and Japanese musical scales utilized in three very distinct systems: theory versus performance practice and the ‘Scale of Fifths’, or cyclic division of the octave; the equally-tempered division of the octave; and the ‘Scale of Proportions’, or harmonic division of the octave championed by Harrison, among others – outlining their theoretical and aesthetic rationale, as well as their historical foundations. The project begins with the creation of three new microtonal works tailored to address some of the compositional issues of each system, and ending with an articulated exposition; obtained via the investigation of written sources, disclosure

  • Listening to String Sound: a Pedagogical Approach To
    LISTENING TO STRING SOUND: A PEDAGOGICAL APPROACH TO EXPLORING THE COMPLEXITIES OF VIOLA TONE PRODUCTION by MARIA KINDT (Under the Direction of Maggie Snyder) ABSTRACT String tone acoustics is a topic that has been largely overlooked in pedagogical settings. This document aims to illuminate the benefits of a general knowledge of practical acoustic science to inform teaching and performance practice. With an emphasis on viola tone production, the document introduces aspects of current physical science and psychoacoustics, combined with established pedagogy to help students and teachers gain a richer and more comprehensive view into aspects of tone production. The document serves as a guide to demonstrate areas where knowledge of the practical science can improve on playing technique and listening skills. The document is divided into three main sections and is framed in a way that is useful for beginning, intermediate, and advanced string students. The first section introduces basic principles of sound, further delving into complex string tone and the mechanism of the violin and viola. The second section focuses on psychoacoustics and how it relates to the interpretation of string sound. The third section covers some of the pedagogical applications of the practical science in performance practice. A sampling of spectral analysis throughout the document demonstrates visually some of the relevant topics. Exercises for informing intonation practices utilizing combination tones are also included.

Hardt Chairman, Department Committee on Graduate Theses Acoustic Function of Sound Hole Design in Musical Instruments by Hadi Tavakoli Nia Submitted to the Department of Mechanical Engineering on May 22, 2010, in partial fulfillment of the requirements for the degree of Master of Science in Mechanical Engineering Abstract Sound-hole, an essential component of stringed musical instruments, enhances the sound radiation in the lower octave by introducing a natural vibration mode called air resonance. Many musical instruments, including those from the violin, lute and oud families have evolved complex sound-hole geometries through centuries of trail and error. However, due to the inability of current theories to analyze complex sound-holes, the design knowledge in such sound-holes accumulated by time is still uncovered. Here we present the potential physical principles behind the historical de- velopment of complex sound-holes such as rosettes in lute, f-hole in violin and multiple sound-holes in oud families based on a newly developed unified approach to analyze general sound-holes. We showed that the majority of the air flow passes through the near-the-edge area of the opening, which has potentially led to the emergence of rosettes in lute family.

Received: 5 January 2012; in revised form: 23 January 2012 / Accepted: 28 January 2012 / Published: 1 February 2012 Abstract: We describe a new dichroic polarizers made by ordering silver nano-fibers to aligned layers. The aligned layers consist of nano-fibers and self-assembled molecular aggregates of lyotropic liquid crystals. Unidirectional alignment of the layers is achieved by means of mechanical shearing. Aligned layers of silver nano-fibers are partially transparent to a linearly polarized electromagnetic radiation. The unidirectional alignment and density of the silver nano-fibers determine degree of polarization of transmitted light. The aligned layers of silver nano-fibers might be used in optics, microwave applications, and organic electronics. Keywords: metal nano-fibers; lyotropic liquid crystals; aligned layers; dichroic polarizers; dichroic ratio; degree of polarization 1. Introduction Modern optical applications, e.g., flexible liquid crystal displays, require a polarizer with large optical aperture, minimized thickness, broad band transmission, and low cost. To resolve such contradictory requirements one may use so-called dichroic film polarizers.

  • Document About Pitch, Pitch Interval, and Pitch Ratio Representation
    Pitch, Pitch Interval and Pitch Ratio Representation Joren Six University College Ghent, Faculty of Music Hoogpoort 64, 9000 Ghent - Belgium [email protected] December 21, 2011 Abstract This document describes how pitch can be represented using various units. More specifically it documents how a software program to analyse pitch in music, Tarsos, represents pitch. Tarsos[3] can be downloaded on http://tarsos.0110.be. This document contains definitions of and remarks on different pitch and pitch interval representations. For good measure we need a definition of pitch, here the definition from [1] is used: The pitch frequency is the frequency of a pure sine wave which has the same perceived sound as the sound of interest. For remarks and examples of cases where the pitch frequency does not coincide with the fundamental frequency of the signal, also see [1]. In this text pitch, pitch interval and pitch ratio are briefly discussed. 1 Pitch & Pitch Interval Representation Since we are interested in a frequency or frequency interval Hertz (Hz), oscilla- tions per second, seems the most appropriate unit. When working with sound this is not always the case. For humans the perceptual distance between 220Hz and 440Hz is the same as between 440Hz and 880Hz. A pitch representation that takes this logarithmic relation into account is more practical for some purposes. Luckily there are a few: MIDI Note Number The MIDI standard defines note numbers from 0 to 127, inclusive. Nor- mally only integers are used but any frequency f in Hz can be represented 1 with a fractional note number n using equation 1.
