Solitude of Sounds

Description: Last October while thinking about a composition I was to realize in the Columbia-Princeton Studio I spent a lot of time in my room listening to distant noises coming in through a half-open window. It was a seemingly disordered mixture of the street hubbub, signals of the river ships, and the distant thunder of planes. After some time I had an impression of all these noises being alive and perhaps even conscious of their existence; it seemed as it they wanted to speak. United into one whole and yet confined only to themselves they created a lonely choir. I wanted to express this feeling in my new composition. Solitude of Sounds does possess a certain plot. In the first phase, the homogeneous sound material exists only at the lowest register, as if unable to "free" itself from the area of darkness and uncertainty. Later, in the higher register, there appear sounds complexes of harmonic structure. They form a kind of a "choir" of aliquots, mutually penetrating and "singing through" one another. However, they are not allowed to create any new quality due to their restricted nature. Circling and persisting, they remain forever imprisoned in their own imperfection. I would like to make it clear that the above comments should be treated only as an expression of a certain consideration on the origins of the piece but in no case as an attempt to reveal some literal dependencies between the inspiration — a definite sound situation — and the piece itself. This situation served only as an impulse to create a certain imaginative space filled with independent sound material governed by its own rules. Perhaps the reason for writing this commentary was a desire to explain my own dislike for music which very distinctly organizes the space by introducing an element ...

Whisper Study (for two electroacoustic sound tracks)

Description: Recording of Hildegard Westerkamp's Whisper Study (for two electroacoustic sound tracks). Whisper Study is based on the sentence "When there is no sound, hearing is most alert" (a quote from the Indian mystic Kirpal Singh. Except for the distant horns, all sounds were derived from the composer's voice, whispering the above sentence and the word "silence." Whisper Study started out as an exercise in exploring basic tape techniques in the analog studio of the 70s and using the whispered voice as sound material. Eventually, it became a piece about silence, aural perception and acoustic imagination. Whisper Study explores the place or moment where sound ends and its image begins. The poem "When There is No Sound" by Norbert Ruebstaat was written in direct response to the original version of Whisper Study. The poem in this version is spoken by the composer inside a soundscape of icicles and footsteps in snow, which originally was created for her radio series Soundwalking on Vancouver Co-operative Radio in 1978/79. Eventually this section was mixed with the last part of the original version of Whisper Study.

Viola celeste

Description: Recording of Michela Mollia's Viola celeste. This work was realized at the Experimental Studio of Electroacoustic Music of the Pesaro Conservatory. Its sound material consists of 950 sinusoids (sine curves) grouped into a mixture of 4 sinusoids each and arranged in 16 sets of 21 mixtures from beginning to end. Each layer (4 complexes) is a rather complex superposition of sinusoidal sounds whose frequencies vary in time so as to avoid the creation of melodies, but to stabilize between one frequency value and the next, a very small interval. "Viola Celeste" is the name of an organ register. The title means by my intention to synthesize the sound of this instrument, or rather more accurately, to create a sort of gigantic uniform "cluster.”

Effetti Collaterali (for clarinet in A and computer generated electronic sounds)

Description: The specified pitches are made to generate their own accompanying frequencies, generally inharmonic with respect to the pitches themselves, as a result of FM or AM procedures. Each interval, or, in fact, each pitch-pair (or if you don't want to limit yourself to the chromatic scale, each pair of arbitrarily decided upon frequencies) can generate several possible spectra, but the similarity in sound quality between kinds of spectra quickly reduces to a limited number of readily manageable families of chord-types. These chords are the basis for a variety of musically interesting relationships, and this work represents but one of many possible developments of these kinds of sounds. The clarinetist in this recording is Philip Rehfeldt.

For Alrun I et II

Description: Recording of Iván Székely's For Alrun I et II. The work entitled "For Alrun" was composed in 1975 in Bayreuth during a live electronics course. The singing part of the play of about 7 minutes, a form and a light local broadcast, contains the popular song tchango beginning with the words "Gyere ki te gyšngyvirag" / come, leave my beautiful, my lily of the valley / - this one will have to be changed to all the presentations in Hungarian. This task was undertaken at the world premiere by Alrun Zahoransky - hence the title of the work. The player applying the electronics, especially from the point of view of the instrumentation, produces sounds and manipulates the electronic sounds and the human voice. The piece does not require studio work, each tone or voice sounds in vivo (i.e. each presentation, each show is new). The focus is on the psychic process of the piece and not on the technical process; its different degrees of difficulty adapt to the possibilities of the presentation. The singer is Ágnes Zsigmondi. The translation of the song is: Come, leave my beautiful, my lily of the valley, Because the moon is mounted, alas. I will leave at dawn, wearing a high hat, alas.

Telesuono Hologram

Description: After an intense period of analog familiarization with the range and enormity of available sounds extraterrestrially and in nature, I tried the only techniques then available to me, tape manipulation and speaker placements. The only coloration that I employed in early sound handling was through equalization, balancing and combining mix-downs. I have always monitored from nearly neutral sensors, and my interest has been in trading, configuring and juxtapositionings and in the presentation of sound in natural and climatically different contexts, mainly exterior and in realtime. Within the 1980s, I worked with 200-speakers using an Intel 8080 microprocessor used for satellite teleperformances, with collaborators and in outdoor "studios." Structure wise my work centers around spaces in spaces, scale and proportion and my soundworks effect an awareness of the psychological effects of sounds, for instance, from trees and wind transformation via my windribbon. I'm concentrating on conceptualizing a segue into Internet 2 realtime with oncall 2way availabilities of my data-laden resources. My basic groundwork includes several recyclings of the TerraInstruments including the signal discs, selfbroadcasting trees, lased raindrops and windribbon variations in an attempt to express the voltages I seek from natural sources as recontextualized audible constructs: offering personal connections to the long term aural memories of earthguests. " The composer's primary interest has been to establish "'an unprecedented access to nature ... in sound'."-- "Blue" Gene Tyranny leif BRUSH '06 4a-LGB'75Telesuono hologram.wav 19:51 Each of these sounds have their in-space "envelopes" and I tried avoiding collisions; however, I was generous with overlaps. And, cyclic repeats assure long term memories. When completed, this was a lay-it-all-out experience expressly for head space. I enjoyed the spatially built manipulations and I was content with my overall context that, since I was the doctor, I knew all the parts; however, it doesn't come close the ...

Program plan for the Brayton Isotope Power System. Phase I. Design, fabrication and test of the Brayton Isotope Power System

Description: Phase I of an overall program for the development of a 500 to 2000 W(e) (EOM), 7-y life, power system for space vehicles is discussed. The system uses a closed Brayton dynamic system to convert energy from an isotope heat source at a net efficiency greater than 25 percent. This first phase, a 35-month effort, is for the conceptual design of a 1300 W(e), 450 lb flight system and the design, fabrication, and test of a ground demonstration system. The flight system will use, for the baseline design, two of the multihundred-watt (MHW) heat sources being developed. The Ground Demonstration System will simulate, as closely as possible, the Brayton Isotope Power Flight System and will utilize components and technology being developed for the Mini-Brayton rotating unit, recuperator and heat source assembly, respectively. The Ground Demonstration System includes a performance test and a 1000-h endurance test.

Field-ion microscope studies of the defect structure of the primary state of damage of irradiated metals

Description: A review is presented of field ion microscope applications in studies of point defect distribution in irradiated metals. FIM results on the primary state of radiation damage in neutron and ion-irradiated iridium and tungsten, at both room-temperature and 78/sup 0/K, showed that it consists of: (1) isolated vacancies; (2) depleted zones; (3) compact vacancy clusters of voids; and (4) dislocation loops. The fraction of vacancies stored in the dislocation loops represented a small fraction of the total vacancy concentration; in the case of tungsten it was approximately 10 percent. These FIM observations provide a simple explanation of the low yield-factor, determined by transmission electron microscopy, for a number of ion-irradiated metals.

Geological-geophysical evaluation of the Hot Springs area, Bath County, Virginia. Progress report, June 1, 1975--February 29, 1976

Description: In the northwestern part of Virginia and adjacent parts of West Virginia there are approximately 100 springs that have temperatures ranging from slightly above the mean air temperature (9 to 12/sup 0/C) to about 41/sup 0/C. A study was made to evaluate the geothermal resource potential of the area in the vicinity of the Warm Springs anticline in Bath and Allegheny Counties, Virginia. Phase I of the study is the compilation of a geologic map based on published maps and supported by reconnaissance and detailed geologic mapping in areas where published maps are not available. Phase II consists of a regional bipole-dipole electrical resistivity survey made in order to detect the presence of resistivity lows that might be associated with a geothermal system at depth. Phase III will include drilling a single hole to a depth of approximately 300 m with the hope of obtaining a heat flow value that is representative of the region. (LBS)

Solid state chemistry of rare earth oxides. Technical progress report, 1974--1975. [High-resolution electron optical methods at 3 A resolution]

Description: Electron microscope images obtained at about 3A resolution for Pr/sub 7/O/sub 12/ (and isomorphous Zr/sub 3/Sc/sub 4/O/sub 12/) are in excellent agreement with calculated images based upon the structure determined separately by total profile neutron powder diffraction analysis. The image calculation programs establish the efficacy of lattice image interpretation in structural terms for these types of related phases whose structures are as yet beyond conventional means to determine. Such images for several other intermediate phases are interpreted and structures proposed. Finally, images of crystals which can be made to undergo reaction within the microscope are interpreted according to the structures involved. These studies reveal the role of intergrowth and topotaxy in these systems. (auth)

Theory of RBE. Third triennial report, 1 January 1967--31 December 1975. [Model based on tracks of heavy ions in nuclear emulsions]

Description: From a single set of themes, the theory of RBE has developed a picture of the response of many biological, physical, and chemical systems to radiations of different quality, that depends on a model of the structure of the tracks of nuclear projectiles in condensed matter. Its characterizations arise from the tracks of heavy ions in nuclear emulsions, as extended to accommodate biological cells. Most recently emulsions have been identified whose radiosensitivity changes with radiation quality parallel those of biological cells. From experimentally determined radiosensitivity parameters, the theory predicts response to a range of radiations, and includes synergistic effects of mixed radiation fields, making it possible to calculate the RBE of a mixed field of neutrons and gamma-rays, and to specify the dosimetric measurements required to make these predictions.

Safety consequences of local initiating events in an LMFBR

Description: The potential for fuel-failure propagation in an LMFBR at or near normal conditions is examined. Results are presented to support the conclusion that although individual fuel-pin failure may occur, rapid failure-propagation spreading among a large number of fuel pins in a subassembly is unlikely in an operating LMFBR. This conclusion is supported by operating experience, mechanistic analyses of failure-propagation phenomena, and experiments. In addition, some of the consequences of continued operation with defected fuel are considered.

Cost comparison of very high temperature nuclear reactors for process heat applications

Description: In April 1974, the United States Atomic Energy Commission (USAEC) authorized General Atomic Company, General Electric Company and Westinghouse Astronuclear Laboratory to assess the available technology for producing process heat utilizing very high temperature nuclear reactors. General Electric and Westinghouse produced concepts for the entire nuclear system, including the balance of plant. The General Atomic assessment included only the nuclear reactor portion of the nuclear plant. United Engineers and Constructors Inc. (UE and C) was requested by the USAEC in November 1974 to prepare an economic comparison of the three conceptual plants. The comparison is divided into three tasks: (1) Develop a balance of plant conceptual design to be combined with the General Atomic concept as a basis for comparison, and estimate the cost of the General Atomic/UE and C concept in July 1974 dollars; (2) Normalize the overall plant costs for the General Atomic/UE and C, General Electric and Westinghouse concepts, compare the costs, and identify significant differences between the concepts; and (3) Estimate the operation and maintenance costs for the General Atomic/UE and C plant and compare with the other concepts. The results of these task studies are discussed.

Fracture and fatigue of high strength filaments. Final report, September 25, 1974--August 30, 1975

Description: The history of high strength filamentary materials is traced and it is seen that their use has been widespread. It is shown that today's demands upon these materials require a better understanding of their behavior than is presently available. Current theories for both the static and fatigue strength of filamentary materials are reviewed. An analysis of static strength tests on short filaments is presented that explains seemingly anomalous test behavior which has been reported in the literature. The proposed approach is supported by experiments and computer analysis. A new machine for the fatigue testing of filaments or wires was designed and is described in detail. Results are presented for fatigue tests on tungsten wire, graphite filaments and glass filaments. Graphite filaments showed an unexpected deterioration in strength after very many cycles (10/sup 8/). An explanation of this effect is offered and supported by scanning electron microscope observations. The work concludes with some suggestions for further research.

Determination of hydroxide in the presence of aluminate using a modified potentiometric titration

Description: A procedure for the determination of hydroxide concentration in the presence of aluminate and other interfering ions was developed using the method of standard additions (or more specifically in this case, standard subtractions). The procedure called for titration with a strong acid which was added in equal increments at regular time intervals. The potential was recorded after each addition of acid. The data was plotted on Gran's Plot Paper, which is based on work done originally by Gran, or it was entered into a computer to determine the equivalence volume of the titrant. When used on many different samples in different matrices, the method gave results that were approximately 100 +- 1 percent of the calculated value. This was shown to be true even in systems containing aluminate (Al(OH)/sub 4//sup -/), phosphate (PO/sub 4//sup 3 -/), sulfate (SO/sub 4//sup 2 -/), nitrate (NO/sub 3//sup -/), nitrite (NO/sub 2//sup -/), carbonate (CO/sub 3//sup 2 -/), and other ions. The effect of these ions was shown to be negligible if the initial OH/sup -/ concentration was at least 10/sup -3/ M and barium chloride (BaCl/sub 2/) was added to complex the PO/sub 4//sup 3 -/ and CO/sub 3//sup 2 -/ ions. These ions were checked at levels of up to 3 M for Al(OH)/sub 4//sup -/ and NO/sub 3//sup -/, 2 M for NO/sub 2//sup -/, and 1 M for SO/sub 4//sup 2 -/, PO/sub 4//sup 3 -/, and CO/sub 3//sup 2 -/. The method is applicable to radioactive as well as nonradioactive samples and any heat involved with a radioactive sample is insufficient to cause an error in the determination. On the basis of the work performed it was shown that the method was general enough to be run on a routine basis.
