Dynamic response of an embedded block impacted by aerated high-velocity jets
Anton Schleiss, Rafael Xavier Meriade Duarte
Uplift of blocks from the rock mass at the bottom of plunge pools is the main process of the scouring phenomenon caused by high-velocity jet impact. Although the influence of water and rock on dynamic block ejection has been investigated, no systematic res ...
Taylor & Francis Ltd2016Single-Layer Quad-Band Printed Reflectarray Antenna with Dual Linear Polarization
Anja Skrivervik, Julien Perruisseau-Carrier, Hamed Hasani
A novel single layer, dual linear polarized unit cell is introduced for a quad-band reflectarray antenna in the Ku-band centered around 12, 13, 14, and 15.5 GHz. The unit-cell design is such that the resultant reflectarray antenna can be considered as four ...
IEEE-Inst Electrical Electronics Engineers Inc2015SolarDecathlon: Energy and water management system analysis at a building scale
This first semester spent working on the Solar Decathlon project aims at defining a compelling concept for the competition. The need for a support for energy considerations was quickly identified to complement the analysis carried out by the architects. Th ...
2014Influence of air entrainment on rock scour development and block stability in plunge pools
Rock scour occurring near dam foundations due to high-velocity jets of spillways impinging into the plunge pool is a major concern regarding dam safety. Scour in fractured rock resulting from high-velocity jet impact is a complex phenomenon, which involves ...
EPFL - LCH2014In-situ localized carbon nanotube growth inside partially sealed enclosures
Carbon nanotube assemblies can be used for specific applications such as sensors and filters. We present a method and proof-of-concept to directly grow vertically-aligned carbon nanotube structures within sealed enclosures by means of a feedback-controlled ...
American Institute of Physics2013Colour simplex coding for brillouin distributed sensors
Luc Thévenaz, Marcelo Alfonso Soto Hernandez
The possibility to customize Simplex coding for long range Brillouin Optical Time Domain Analysis is demonstrated by “colouring” the sequences in the frequency domain. The coding gain is identical to the traditional intensity-modulated Simplex code, though ...
2013Optical classification of algae species with a glass lab-on-a-chip
The identification of submillimetre phytoplankton is important for monitoring environmental and climate changes, as well as evaluating water for health reasons. Current standard methods for phytoplankton species identification require sample collection and ...
2012Energy and water conservation from air handling unit condensate in hot and humid climates
This study investigates the potential for energy and water sustainability in hot and humid climates by utilizing the condensate captured from large dedicated air handling units (AHUs) for pre-cooling outdoor air in another AHU and subsequently offsetting c ...
2012Response of an embedded block impacted by high-velocity jets
Matteo Paolo Elia Antonio Federspiel
The safety of dams is very often endangered by the formation of scour near the foundation as a result of high-velocity jet impact. These jets issue from appurtenant structures such as spillways and may impact in the immediate vicinity of the dam toe. The p ...
EPFL - LCH2011Influence of a circular jet arrangement in a rectangular tank on flow and suspended sediment release
Jolanda Maria Isabella Jenzer Althaus
With the objective of high sediment release out of a rectangular tank the performance of a circular jet arrangement has been investigated. Therefore, experiments with four jets arranged in a horizontal circle placed in water with quasi homogeneous sediment ...
