Period and amplitude of bedload pulses in a macro-rough channel

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

It is known that bedload fluctuates over time in steep rivers with wide grain size distributions, even under conditions of constant sediment feed and water discharge. Bedload fluctuations, which are a consequence of grain sorting, are periodic and are rela ...

The economic performance of Swiss drinking water utilities

Andrea Baranzini, Anne-Kathrin Faust

This paper measures the performance in terms of costs of Swiss drinking water utilities accounting for environmental factors. We estimate a translog stochastic variable cost frontier using two different techniques on an unbalanced panel of 141 water distri ...

Optimization of operation conditions for the startup of aerobic granular sludge reactors biologically removing carbon, nitrogen, and phosphorous

Christof Holliger, Samuel Lochmatter

The transformation of conventional flocculent sludge to aerobic granular sludge (AGS) biologically removing carbon, nitrogen and phosphorus (COD, N, P) is still a main challenge in startup of AGS sequencing batch reactors (AGS-SBRs). On the one hand a rapi ...

Academic Cooperation to Foster Research and Advocacy Competences in the Occupied Palestinian Territory (West Bank)

Martin Schuler, François Golay, Claudio Magalhaes Carneiro, Béatrice Métaireau

Palestinians living in the West Bank, a territory occupied by the State of Israel according to International Law, face deprived access to land and a limited ability to move freely which pertains to the presence of Israeli settlements and other infrastructu ...

Deployment of a dynamic penetrometer from manned submersibles for fine-scale geomorphology studies

David Andrew Barry, Ulrich Lemmin, Nicolas Le Dantec

Dynamic penetrometers reveal information about seafloor strength, stratification, stability, and sediment remobilization. However, positioning is often limited to a range of meters making it difficult to target small-scale geomorphologic features. Deployme ...

Impact analysis of a flexible air transportation system

Michel Bierlaire, Claudio Leonardi, Matteo Salani, Bilge Atasoy

The paper provides analytical evidence of the added-value of flexibility for air transportation systems. More specifically, the impact of a new innovative modular aircraft on the operations of an airline is deeply analyzed. The impact analysis is carried o ...

Intra-particle dynamics and the impact response of granular chains

Alessandro Spadoni, Bart Van Damme

Low-frequency waves generated by an impact on an isostatic granular medium with vanishing confinement pressure are theorized to depend on rigid-particle collisions. According to this model, an impact generates a solitary wave spanning several particle diam ...

The structure of the asteroid 4 Vesta as revealed by models of planet-scale collisions

Philippe Gillet

Asteroid 4 Vesta seems to be a major intact protoplanet, with a surface composition similar to that of the HED (howardite-eucrite-diogenite) meteorites(1-4). The southern hemisphere is dominated by a giant impact scar(5), but previous impact models(6-8) ha ...
