1. 1. Phainesthai : Auditory Processes as Tools for Musical Composition

   University essay from Kungl. Musikhögskolan/Institutionen för komposition, dirigering och musikteori

   Author : Luka Aron; [2023]
   Keywords : music; psychoacoustics; auditory distortion products; tuning; just intonation; phenomenology;

   Abstract : The human auditory system can become an active agent in the production of sound when stimulated with specific tone combinations. The resulting auditory distortion products can be amplified and drawn attention to by employing certain just intonation practices – a compositional technique that may serve as a powerful catalyst for reaching different states of mind in listeners.

3. 2. The Uniformization Theorem

   University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

   Author : Nikita Zozoulenko; [2021]
   Keywords : complex analysis; riemann surface; analytic functions; holomorphic functions; differential geometry; harmonic; subharmonic; perron; analysis; Mathematics and Statistics;

   Abstract : In this bachelor's thesis we provide a self contained proof of the Uniformization Theorem. It states that a simply connected Riemann surface is conformally equivalent to either the complex plane C, the unit disk D, or the Riemann sphere C^*. READ MORE

4. 3. Subharmonic Imaging of Polymer-Shelled Contrast Agents

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Rúnar Sigmundsson; [2018]
   Keywords : Ultrasound Imaging; Contrast Enhanced Ultrasound Imaging; Contrast Agents; PVA Contrast Agents;

   Abstract : The harmonic generation due to the nonlinear behavior of Ultrasound Contrast Agents (UCAs) must be exploited for improved efficiency when imaging vascular targets in the neighborhood of highly echogenic tissue. One may even further improve the efficiency by focusing on the subharmonic generation of the UCAs, which is an even more exclusive property than the generation of higher harmonics, for improved Contrast-to-Tissue ratio (CTR).

5. 4. Ultraharmonic Imaging of Polymer-shelled Microbubbles

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Dimitrios Evangelou; [2018]
   Keywords : Subharmonic Imaging; Ultraharmonic Imaging; Polyvinyl Alcohol; PVA; Verasonics; Ultrasound Contrast Agents; Non-linear imaging; Contrast-to-Tissue ratio.;

   Abstract : Ultrasound has been established as one of the most widely used imaging modalities for diagnostic purposes, due to the several advantages it provides in comparison with other techniques. Hence, ways to further improve the confidence in diagnoses provided by ultrasound are constantly being investigated. READ MORE

6. 5. Parameter Study of Ferro-Resonance with Harmonic Balance Method

   University essay from KTH/Elektriska energisystem

   Author : Ali Erbay; [2012]
   Keywords : ;

   Abstract : Ferro‐resonance is an electrical phenomenon which can cause damage to electrical equipments of power systems by its characteristic steady state over voltages and over currents. Configurations where ferro‐resonance is possible has more than one steady state operation. READ MORE
