2. 1. Reconstructing force from harmonic motion

   Author : Daniel Platz; David B. Haviland; John E. Sader; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oscillator; force spectroscopy; atomic force microscopy; intermodulation; multifrequency; inverse problem; high quality factor;

   Abstract : High-quality factor oscillators are often used in measurements of verysmall force since they exhibit an enhanced sensitivity in the narrow frequencyband around resonance. Forces containing frequencies outside this frequencyband are often not detectable and the total force acting on the oscillatorremains unknown. READ MORE

4. 2. Relaxation and Resonance in Brownian Motion-Coupled Resonators

   Author : Christin Rhen; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nonequilibrium dynamics; nonlinear dynamics; resonance; nanomechanics; relaxation; superconducting circuits.; resonator; dispersive coupling; noise; Brownian motion;

   Abstract : In physics, there exists a number of paradigm systems – exactly solvable models that can represent a wide variety of physical realizations. My research is concerned with two of these paradigm systems: the harmonic oscillator and Brownian motion. READ MORE

5. 3. A Quantitative Rule System for Musical Performance

   Author : Anders Friberg; Johan Sundberg; Giovanni Di Poli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; music performance; expression; interpretation; rules; computer music; midi; jnd; time discrimination; locomotion; motion; listening experiment; perception; timing; phrasing; intonation; Speech and Music Communication; Tal- och musikkommunikation;

   Abstract : A rule system is described that translates an input score file to a musical performance. The rules model different principles of interpretation used by real musicians, such as phrasing, punctuation, harmonic and melodic structure, micro timing, accents, intonation, and final ritard.

6. 4. Quantification of cardiovascular flow and motion : aspects of regional myocardial function and flow patterns in the aortic root and the aorta

   Author : John-Peder Escobar Kvitting; Henrik Egeblad; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Quantification of cardiovascular flow and motion is essential in the diagnosis, treatment and follow-up of cardiovascular disease. The accuracy and quantification of many imaging methods used in this field have important shortfalls, however, that result from limitations in spatial and temporal dimensions. READ MORE

7. 5. Ultrasound Contrast Agents Loaded with Magnetic Nanoparticles : Acoustic and Mechanical Characterization

   Author : VeeraVenkata Satyanarayana Kothapalli; Lars-Åke Brodin; Jan Engvall; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound contrast agents; SPION nanoparticles; harmonic oscillation; backscattering power; attenuation coefficient; phase velocity; nonlinear equation of motion;

   Abstract : The current methodologies in body scanning diagnostic uses different simultaneous imaging modalities like Ultrasound (US), magnetic resonance imaging (MRI), single photon emission tomography (SPECT) and positron emission tomography (PET). The field requires combination of different modalities for effective use in clinical diagnostics. READ MORE
