Wearing glasses to hear differently? Aftereffects of visuomanual prismatic adaptation on auditory perception
2022
Sensorimotor plasticity is defined as the ability to produce an appropriate motor response face to environmental or bodily changes. The classical experimental paradigm to study sensorimotor plasticity is prism adaptation, which consists of pointing to visual targets while wearing prisms that shift the visual field laterally or vertically. Its aftereffects are not restricted to sensorimotor behavior but extend to sensorial modalities not directly involved during prism exposition, such as audition. There exists a mental representation of auditory frequencies in which low auditory frequencies are associated with the left part of space and high auditory frequencies with the right part of space.…
A computational method to optimal control of a wind turbine system using wavelets
2011
Author's version of a chapter in the book: Proceedings of the IEEE International Syposium on Computer-Aided Control System Design (2011). Also avaliable from the publisher at: http://dx.doi.org/10.1109/CACSD.2011.6044551 This paper deals with a computational optimization approach to the problem of state-feedback control design for a wind turbine system. The first step of the study is to develop a reduced order model for the system by considering the most important physical phenomena of aerodynamics and structural dynamics. Moreover, the behavior of the system can be influenced by the coupled dynamics between the tower motions and the blade pitch and turbine speed which can cause instabiliti…
Bond graph modeling and simulation of wind turbine systems
2013
Published version of an article in the journal: Journal of Mechanical Science and Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s12206-013-0435-x This paper addresses the problem of bond graph methodology as a graphical approach for the modeling of wind turbine generating systems. The purpose of this paper is to show some of the benefits the bond graph approach has, in contributing a model for wind turbine systems. We will present a nonlinear model of a wind turbine generating system, containing blade pitch, drive train, tower motion and generator. All which will be modeled by means of bond graph. We will especially focus on the drive train, and show the differ…
The origins of the aesthetic enjoyment of music - A review of the literature
2009
Listeners attribute a positive or negative value to music. This aesthetic experience is known to be observable over the individuals’ entire life span, from early childhood to old age, and in every culture. It is then often concluded that such an aesthetic experience constitutes part of the human nature, having an important biological foundation. This assumption leads to the question of how aesthetic experience of music originated in the biological evolution. In this paper, we will explore this question in the light of evolutionary psychology, cognitive science, and systems neuroscience. After reviewing the existing proposals, we conclude that the explanation of the origin of aesthetic expe…
Classroom application of using visual stimuli in learning dynamics and pitch
2014
Listening is a common activity in music lessons. It is difficult for teachers to know whether students are learning by listening. In this study, visual stimuli include imagery, metaphor, and symbols, were introduced to students in the experimental group to learn dynamics and pitch. A control group received the same lessons without any visual stimuli. Both groups received the same tests, pre-test and post-test, after the two lessons. Tests were divided into two parts including choosing the correct dynamic changes and distinguishing higher or lower pitch for the melody. Results showed the experimental group had improved more than the control group. The change of the experimental group in rela…
Classroom application of using visual stimuli in teaching and learning dynamics and pitch

Acquiring music information : An incidental learning approach.
2022
This thesis contains my empirical works resulting from three years of studying contingency learning, that is the human ability to learn regularities between two or more events, applied to music. Learning music requires time and effort. However, many skills can be automatized in less time-consuming and effortful ways. Indeed, some research suggests that many elements of music knowledge are mostly implicitly acquired. In Chapter 1, the potential benefit of using an incidental learning procedure to automatize musical sub-skills useful for sight-reading and for pitch identification is discussed. In Chapter 2, the first set of experiments investigate whether an incidental contingency learning ta…
Do absolute pitch possessors have a field independent cognitive style?
2009
The factors contributing to the development of absolute pitch (AP) are still not fully understood. It seems to be neither completely inherited nor completely teachable. This study tested the hypothesis, that individual differences in cognitive style influence AP development. Specifically, it investigated whether adult AP possessors can be characterized by a field independent cognitive style while handling visual and musical tasks. Thirty professional musicians performed tests of absolute and relative pitch abilities, a visual and a musical task measuring field independence, and visual tasks measuring intellectual functioning. The absolute pitch test resulted in a continuous distribution of …
Phantomuntersuchung zur Optimierung der Spiral-CT und 3 D-Rekonstruktion des Tracheobronchialsystems
1996
PURPOSE To optimise three-dimensional spiral CT of the tracheobronchial tree using adequate acquisition and reconstruction parameters for spiral CT of the chest. MATERIAL AND METHODS Qualitative and quantitative assessment of different 3 D reconstructions of two test objects of the tracheobronchial tree depending on section thickness, reconstruction interval, pitch, and reconstruction algorithm used in spiral CT (Siemens, Somatom plus S) of the chest. The frequency of volume and stairstep artifacts was evaluated. The 3 D reconstructions were generated using a seeded VOI-technique (Allegro, ISG). RESULTS Reduction of artifacts was achieved by decreasing section thickness. Increasing overlap …
Analysis of Early 20th century Chromatic Modal Music with the use of the Generative Theory of Tonal Music - Pitch Space and Prolongational issues in …
2009
The Generative Theory of Tonal Music in its original form (Lerdahl & Jackendoff 1983) applied to music belonging to the Western tonal idiom only. However, during the last decade, theoretical and analytical research has been conducted on its application on diatonic or chromatic modal music. More specifically, Lerdahl addresses chromatic pitch spaces in chapters 6 & 7 of his "Tonal Pitch Space" (2001) and conducts analyses of late 19th century and 20th century music, while Temperley (The Cognition of Basic Musical Structures, 2001) and Tsougras (Modal Pitch Space, 2003) explore mainly the diatonic modal space. The present paper aims to clarify the concepts of modal mixture, modal interchange,…
