Exploiting Marginal Stability in Slow-Fast Quasilinear Dynamical Systems

The accurate investigation of many geophysical phenomena via direct numerical simulations is computationally not possible nowadays due to the huge range of spatial and temporal scales to be resolved. Therefore advances in this field rely on the development ...

Explaining multiple patches of aquatic vegetation through linear stability analysis

Giulio Calvani

Aquatic vegetation is ubiquitous in lowland rivers, and it is typically present in the shape of spatial self-organized patches of biomass. In this work, we mathematically define the threshold conditions for the incipient formation of self-organized vegetat ...

Historical dynamics of ecosystem services and land management policies in Switzerland

Jérôme Chenal, Martí Bosch Padrós, Stéphanie Aline Hasler, Rémi Jaligot

Ecosystem services (ES) are dynamic over space and time. Understanding and quantifying spatio-temporal trade-offs and synergies among multiples ES, as well identifying the drivers of change provides an opportunity to make the link between ecosystems, polic ...

Strengthening of steel beams using iron-based shape memory alloy (Fe-SMA) strips

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori, Julien Michels

The current study presents a retrofit system, which can be used for strengthening of steel bridge beams using (un-bonded) mechanically-anchored iron-based shape memory alloy (Fe-SMA, ‘memory-steel’) strips. After anchoring, the Fe-SMA strips are activated ...

On the Design of Economic NMPC Based on an Exact Turnpike Property

Dominique Bonvin, Timm Faulwasser

We discuss the design of sampled-data economic nonlinear model predictive control schemes for continuous-time systems. We present novel sufficient convergence conditions that do not require any kind of terminal constraints nor terminal penalties. Instead, ...

On the mechanism of the Gent–McWilliams instability of a columnar vortex in stratified rotating fluids

Eunok Yim

In stably stratified and rotating fluids, an axisymmetric columnar vortex can be unstable to a special instability with an azimuthal wavenumber m=1 which bends and slices the vortex into pancake vortices (Gent & McWilliams Geophys. Astrophys. Fluid Dyn., v ...

Adapting to Socioeconomic Developments by Changing Rules in the Governance of Common Property Pastures in the Swiss Alps

Claudia Rebeca Binder Signer, Ivo Philippe Baur

The common property meadows in the Swiss Alps have been managed by local self-organized governance systems since the Middle Ages, thus preventing their overuse. During the past century, socioeconomic developments, such as industrialization and rapid nonagr ...

Biological reduction of chlorinated solvents: Batch-scale geochemical modeling

David Andrew Barry, Clare Robinson

Simulation of biodegradation of chlorinated solvents in dense non-aqueous phase liquid (DNAPL) source zones requires a model that accounts for the complexity of processes involved and that is consistent with available laboratory studies. This paper describ ...

Biothermodynamics of live cells: a tool for biotechnology and biochemical engineering

Urs von Stockar

The aim of this contribution is to review the application of thermodynamics to live cultures of microbial and other cells and to explore to what extent this may be put to practical use. A major focus is on energy dissipation effects in industrially relevan ...

Can microbial growth yield be estimated using simple thermodynamic analogies to technical processes?

Urs von Stockar

In view of the prime importance of the biomass yield in microbial growth for research, for environmental and for industrial applications some thermodynamic concepts are reviewed that were developed over the years in order to understand the large variations ...
