Gesture interaction in music for instruments and electroacoustic sounds

Esta tese apresenta alguns aspectos em como o fen��meno do gesto musical pode ser compreendido na percep����o da intera����o musical na m��sica para instrumentos e sons electroac��sticos. Atrav��s de exemplos de an��lise, classifica����o e categoriza����o de diferentes relac��es gestuais entre instrumentos e sons electroac��sticos, pretende-se estabelecer modelos espec��ficos de interac����o que podem ser aplicados como m��todo anal��tico assim como na composi����o musical. A pesquisa parte de uma variedade de defini����es sobre gesto musical na m��sica em geral, na m��sica contempor��nea e na m��sica electroac��stica em particular, para subsequentemente incluir as rela����es entre dois eventos sonoros com caracter��sticas diferentes - o electroac��stico e o instrumental. S��o essencialmente abordadas as rela����es entre gestos musicais atrav��s da an��lise de diversas caracter��sticas: altura, ritmo, timbre, din��mica, caracter��sticas contrapont��sticas, espectromorfol��gicas, sem��nticas e espaciais. O resultado da pesquisa te��rica serviu de suporte �� composi����o de diversas obras, onde estes aspectos s��o explorados sob o ponto de vista da cria����o musical.

Accessibility instruments for planning practice: A review of European experiences

Although a large body of literature has been produced on the theoretical definitions and measurements of accessibility, the extent to which such indicators are used in planning practice is less clear. This research explores the gap between theory and application by seeking to understand what the new wave of accessibility instruments (AIs) prepared for spatial and transport planning practice purports to offer the users of AIs. Starting from the question of how urban and transport planners are designing AIs, the article analyzes and describes the AIs developed over the last decade (mainly in Europe), offering a structured overview and a clear categorization of how accessibility measures can be applied. The paper identifies AI characteristics, and considers their usability, based on AI developer perceptions.

Fatigue life assessment of endodontic instruments subjected to multi planar curvature

This present study aimed to investigate the fatigue life of unused (new) endodontic instruments made of NiTi with control memory by Coltene��� and subjected to the multi curvature of a mandibular first molar root canal. Additionally, the instrument���s structural behaviour was analysed through non-linear finite element analysis (FEA). The fatigue life of twelve Hyflex��� CM files was assessed while were forced to adopt a stance with multiple radius of curvature, similar to the ones usually found in a mandibular first molar root canal; nine of them were subjected to Pecking motion, a relative movement of axial type. To achieve this, it was designed an experimental setup with the aim of timing the instruments until fracture while worked inside a stainless steel mandibular first molar model with relative axial motion to simulate the pecking motion. Additionally, the model���s root canal multi-curvature was confirmed by radiography. The non-linear finite element analysis was conducted using the computer aided design software package SolidWorks��� Simulation, in order to define the imposed displacement required by the FEA, it was necessary to model an endodontic instrument with simplified geometry using SolidWorks��� and subsequently analyse the geometry of the root canal CAD model. The experimental results shown that the instruments subjected to pecking motion displayed higher fatigue life values and higher lengths of fractured tips than those with only rotational relative movement. The finite element non-linear analyses shown, for identical conditions, maximum values for the first principal stress lower than the yield strength of the material and those were located in similar positions to the instrument���s fracture location determined by the experimental testing results.

Evaluation ��thique en psychologie : une utilisation respectueuse des diff��rents instruments psychom��triques

Trois psychologues de l'Universit�� de Lausanne, Sophie Perdrix, Linda Charvoz et J��r��me Rossier, abordent dans leur article la relation complexe que le psychologue entretient avec les ��valuations psychologiques. Ils plaident en faveur d'une utilisation respectueuse des diff��rences individuelles des instruments d'��valuation et mettent en garde contre leurs aspects r��ductionnistes.
