Ida Gotkovsky's Eolienne Pour Flute et Harpe in Theory and Practice: A Critical Analysis [PDF]
, 2010 This dissertation addresses specific theoretical issues within Gotkovsky's Eolienne. She was a student of Messiaen, and his influence is evident in Eolienne, but at the same time, Gotkovsky's compositional voice is both personally distinctive and ...

Unsteady flow field in a mini VAWT with relative rotation blades: analysis of temporal results [PDF]
, 2013 The present wind turbine is a small one which can be used on roofs or in gardens. This turbine has a vertical axis. Each turbine blade combines a rotating movement around its own axis and around the main rotor axis.

Mineral dust emissions from proglacial valleys of western Canada: Historical and future dynamics
Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.Mineral dust emissions from proglacial valleys of western Canada remain unaccounted for in regional‐global estimates. We record 6‐years of dust emission activity and constrain meltwater and snow cover dynamics from 1984 to 2023, constraining key erodibility controls for aeolian processes.

EFFET DE L’ESPACEMENT ENTRE LES PALES D’UNE EOLIENNE SAVONIUS SUR LA PRODUCTION DE L’ENERGIE
, 2023 Cette étude a contribuée, en première étape, à l’analyse de l’écoulement autour de l’éolienne et à la compréhension du phénomène complexe lié à cet écoulement. En effet, l’effet de l’espacement entre les pales d’une eolienne savonius sur la production de

L’opposition aux projets éoliens terrestres, une forme de contestation « territorialisée »
Géographie et Cultures, 2020 The aim of the article is to understand how opposition to wind energy is expressed locally, both in terms of substance and form, in order. The study illuminates the "paradox" of the energy transition: on the one hand, a relatively good acceptability of ...

Wind Energy, Volume 28, Issue 2, February 2025.ABSTRACT The installation of automatic detection systems (ADSs) on operating wind energy facilities is a mitigation measure to reduce bird collisions. The effectiveness of an ADS depends on a combination of parameters, including the detection distance of the bird, its flight speed, and the time to complete the chosen action (e.g., turbine shutdown). We

Unsteady simulation of flow in micro vertical axis wind turbine [PDF]
, 2010 Though wind turbines and windmills have been used for centuries, the application of aerodynamics technology to improve reliability and reduce costs of wind-generated energy has only been pursued in earnest for the past 40 years.
