1. Hydro-Geomechanical Observations During Multistage Hydraulic Stimulation at the Bedretto Underground Laboratory, Switzerland 

   Bröker, Kai; Ma, Xiaodong; Gholizadeh Doonechaly, Nima; et al. (2023)

   Proceedings of the 57th U.S. Rock Mechanics/Geomechanics Symposium

   A series of hydraulic stimulation experiments were performed in the Bedretto Underground Laboratory for Geosciences and Geoenergies in Switzerland to answer questions about the creation of an engineered geothermal reservoir in crystalline rocks. A 400 m long stimulation borehole was divided into 15 intervals by a multi-packer system. In this work, we present preliminary results of interval 8 in which two injection phases were performed ...

2. UNRAVELLING CAUSES OF BIODIVERSITY GRADIENTS IN TETRAPODS VIA ECO-EVOLUTIONARY SIMULATIONS 

   Bach, Wilhelmine (2024)

   Species and clades of tetrapods - amphibians, birds, mammals and reptiles - are not distributed randomly across the globe but follow gradients of latitude, elevation as well as varying in space and time. These biodiversity gradients in tetrapods vary equally depending on which dimension of diversity - taxonomic, phylogenetic or functional - is studied and which metric is used to summarize that specific dimension. Different metrics quantifying ...

3. Impact-based forecast for critical infrastructure during Tropical Cyclones 

   Espejo Gutierrez, Gabriela (2024)

   Critical infrastructures, such as healthcare facilities or roads, play a vital role in society as they provide essential services for the functioning of communities. Disruptions to these infrastructures have far-reaching consequences, affecting public health, safety, security, wellbeing, and economic activities. Weather extremes, such as tropical cyclones or floods, can lead to widespread failures in lifeline services such as power, ...

5. Robust parametrically varying attitude controller designs for the X-33 vehicle 

   Smith, Roy; Ahmed, Asif (2000)

   AIAA Guidance, Navigation and Control Conference and Exhibit ~ AIAA Guidance, Navigation, and Control Conference and Exhibit

   Robust linear parameter varying (LPV) control design techniques are applied to the attitude control of the X-33, a single-stage to orbit prototype vehicle. The focus of the research is to develop techniques which will allow for a variety of trajectories without significant redesign of the control system. The LPV design method is described, and applied to a representative problem: control of the pitch axis dynamics during ascent. The work ...
