Performance-based Design of Energy Pile Foundations

Alessandro Francesco Rotta Loria

Over the past twenty years, an increasing amount of research has been performed to understand the multiphysical behaviour and to address the geotechnical and structural design of so-called energy piles, i.e. deep foundations that can serve any superstructu ...

NoCs:a Short History of Success and a Long Future

Giovanni De Micheli

The broad application of NoCs in IC design has been enabled by NoC synthesis tools that evolved from university prototypes to full commercial synthesis flows. NoC embodiments are ubiquitously present in circuits and systems. As systems evolve to include ne ...

Towards Ultrasound Everywhere: A Portable 3D Digital Back-End Capable of Zone and Compound Imaging

Jean-Philippe Thiran, Giovanni De Micheli, Federico Angiolini, Marcel Arditi, Aya Mohamed Naguib Ahmed Ibrahim, Shuping Zhang

Ultrasound imaging is a ubiquitous diagnostic technique, but does not fit the requirements of the telemedicine approach, because it relies on the real-time manipulation and image recognition skills of a trained expert, called sonographer. Sonographers are ...

Temporal variability of secondary processes in alkaline geothermal waters associated to granitic rocks: the Caldes de Boi geothermal system (Spain)

The Caldes de Boi geothermal waters show important differences in pH (6.5-9.6) and temperature (15.9 degrees C-52 degrees C) despite they have a common origin and a very simple circuit at depth (4km below the recharge area level). These differences are the ...

Thermally induced group effects among energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria

The behaviour of conventional pile groups (e.g. closely spaced) that are subjected to mechanical loads has been shown to be different from the behaviour of single isolated piles. The so-called 'group effects' are responsible for this behaviour and must be ...

Potential contributions of wind power to a stable and highly renewable Swiss power supply

Michael Lehning, Annelen Kahl

Using data from two measurement networks, we analyse the following aspects of wind speeds over Switzerland to assess the possibility of high wind power penetration: spatial correlation, persistent low wind power conditions and the diurnal and seasonal wind ...
