2. 1. Sound Notation : The visual representation of sound for composition and analysis

   Author : Sköld Mattias; Roberto Bresin; Henrik Frisk; Kjetil Falkenberg; Craig Vear; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; notation; aural sonology; music analysis; electroacoustic music; computer-aided composition; Media Technology; Medieteknik;

   Abstract : This compilation thesis details steps taken to develop and evaluate a new Sound Notation system for composition, analysis, and transcription with the capacity to describe all types of sound. Ideas from electroacoustic music analysis are combined with traditional notation to form a hybrid system. READ MORE

4. 2. SOUnd-DRIven BIOtechnology

   Author : Nasim Najjarzadeh; Paul Christakopoulos; Cristhian Álvaro Carrasco Villanueva; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : Ultrasound has been vastly applied in different areas such as medical imaging and the food industry, but not much attempt has been made to investigate its influence on microorganisms and its potential to be applied in microbial biotechnology. Previous studies show the potential of acoustic waves to increase biomass yield, production of secondary metabolites and enhanced enzyme-catalyzed reactions, probably due to improved mass transfer and cell retention.

5. 3. Textile Sound Design

   Author : Margareta Zetterblom; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; The Cresson Institute; Textile design; acoustics; phenomenography; sound environment; sound absorbing textiles; Pierre Schaeffer; phenomenology; interactive textile design; textile sound design;

   Abstract : There are a number of ways to describe the aesthetical expression of a textile, but how is it possible to express its sound affecting qualities? This thesis aims at developing conceptual and methodological tools in order to adapt sound within the textile design area. Occupational groups working with sound are to a large extent problem driven.

6. 4. Towards measuring quantum sound

   Author : Maria Ekström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface acoustic wave; interdigital transducer; artificial atom; qubit; superconducting circuits; cryogenic temperature; phonon; gigahertz frequency; quantum acoustics; unidirectional transducer;

   Abstract : One of the most fundamental phenomena occurring in nature is the interaction between single atoms and electromagnetic fields. This is studied in quantum optics to probe the quantum nature of the system. In appended Paper I, we demonstrated that an artificial atom can couple to propagating sound, which is the acoustic analogue of quantum optics. READ MORE

7. 5. Absorption of Sound : On the effects of field interaction on absorber performance

   Author : Anna Färm; Mats Åbom; Ragnar Glav; Susann Boij; Gareth Bennett; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; Porous absorbers; Bulk reaction; Local reaction; Boundary layer; Grazing flow; Temperature gradients; Surface impedance; Sound field; Pass-by noise; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. READ MORE
