The Garden and Landscape as an Interdisciplinary Resource Between Experimental Science and Artistic-Musical Expression: Analysis of Competence Develo…

2020

The garden is a major educational resource that can be used for all areas of knowledge from an interdisciplinary perspective as it reflects the complexity and interactions of the natural environment. This research was carried out in the academic years 2017-2018 and 2018-2019 with 418 participants of from the second, third, and fourth year of the Degree in Primary Education at the University of Valencia. The use of the garden and the landscape is analyzed as a non-formal context for training primary school teachers through sensory experiences that contribute to the development of scientific and artistic competencies. The study focused on the relationship between natural sounds and emotions t…

I festeggiamenti per le incoronazioni a Palermo di Vittorio Amedeo II (1713) e Carlo III (1735): musica, spettacolo e cerimonia

2018

Le entrate e le rispettive incoronazioni a Palermo di Vittorio Amedeo II di Savoia e Carlo III di Borbone sono state analizzate sotto diversi punti di vista. Tuttavia gli aspetti musicali sono stati finora poco considerati, se non a margine di studi più generali sulla vita musicale palermitana. Il presente contributo è riservato in modo specifico alla cornice sonora dei due eventi, dimostrando come questa costituisse un elemento essenziale al funzionamento della festa e al soddisfacimento dei suoi scopi. Le descrizioni e le testimonianze iconografiche propongono spunti di indagine sulle modalità di esecuzione e sui rapporti con il contesto celebrativo, fornendo anche informazioni sulle occa…

Stéréophonie et littérature : résonnance et reverbération dans les chansons de gestes et romans des XIIe et XIIIe siècles

2016

The chansons de geste and chivalric romances from the 12th and 13th centuries are a faithful testimony of the reality of their time, and sensory perceptions are among these testimonies. The written word provides not only descriptive and objective information, but also the impressions perceived and conveyed by the author, which are the sensations the reader has to get acquainted with in order to make the story their own. Mentions to sound effects and the sound features of a particular space are remarkable, and a compilation of these references from various texts allows us to study the sounds, resonances, and spaces through which the sound event gains prominence in the narrative. These includ…

Molecular Dynamics Study of Copper and Aluminum under Mechanical Strain

1998

AbstractMechanical properties of copper and aluminum have been studied using finite temperature molecular dynamics simulations. Atomic interactions have been described by a many-atom effective medium potential, which takes into account interactions up to third neighbors. The computed elastic constants showed good agreement with experimental data. Encouraged by these results the model was applied to study fracture in copper. Systems with a grain boundary and an initial cut serving as a crack seed have been studied. In the first case, crack nucleation and propagation took place exclusively at the grain boundary. In the second case, dislocation propagation was observed in one of the <110&gt…

A method to estimate the path gains and propagation delays of underwater acoustic channels using the arrival phase information of the multipath compo…

2017

Abstract We propose a method for the estimation of the channel parameters of underwater acoustic channels (UACs) by using a pseudo-noise (PN) sequence. For the channel sounding, the PN sequence is coherently modulated on a carrier frequency by using a binary phase-shift keying (BPSK) modulation scheme. For the demodulation, the arrival phases of the received BPSK signals must be known at the receiver. In practice, however, the arrival phases of the received signal are unknown. We propose to demodulate the received BPSK signal by using an hypothetical arrival phase, which will be increased from 0 to 2 π . The demodulated signal obtained by using the hypothetical arrival phase is then correla…

Improved Statistically Based Retrievals via Spatial-Spectral Data Compression for IASI Data

2019

In this paper, we analyze the effect of spatial and spectral compression on the performance of statistically based retrieval. Although the quality of the information is not com- pletely preserved during the coding process, experiments reveal that a certain amount of compression may yield a positive impact on the accuracy of retrievals. We unveil two strategies, both with interesting benefits: either to apply a very high compression, which still maintains the same retrieval performance as that obtained for uncompressed data; or to apply a moderate to high compression, which improves the performance. As a second contribution of this paper, we focus on the origins of these benefits. On the one…

Non-speech voice for sonic interaction: a catalogue

2016

This paper surveys the uses of non-speech voice as an interaction modality within sonic applications. Three main contexts of use have been identified: sound retrieval, sound synthesis and control, and sound design. An overview of different choices and techniques regarding the style of interaction, the selection of vocal features and their mapping to sound features or controls is here displayed. A comprehensive collection of examples instantiates the use of non-speech voice in actual tools for sonic interaction. It is pointed out that while voice-based techniques are already being used proficiently in sound retrieval and sound synthesis, their use in sound design is still at an exploratory p…

Molecular-dynamics study of copper with defects under strain

1998

Mechanical properties of copper with various types of defects have been studied with the molecular-dynamics method and the effective-medium theory potential both at room temperature and near zero temperature. The loading has been introduced as constant rate straining and the dynamics of the process region of fracture is purely Newtonian. With the model three types of defects were studied: point defects, grain boundary, and an initial void serving as a crack seed. Point defects were seen to decrease the system strength in terms of fracture stress, fracture strain, and elastic modulus. Due to random microstructure, highly disordered systems turned out to be isotropic, which on the other hand …
