High-throughput analysis of the morphology and mechanics of tip growing cells using a microrobotic platform

Mahmut Selman Sakar, Dimitrios Felekis, Geraldo Mecja

We present a microrobotic platform that combines MEMS-based capacitive force sensing technology, a dual-stage positioning system and a real-time control and acquisition architecture with computer vision automation to manipulate and mechanically characteriz ...

Plant detoxification capacity of xenobiotic compounds as limiting factor for phytoremediation

Jean-Paul Schwitzguebel

Plants have efficient mechanisms for detoxification and sequestration of xenobiotic chemicals and trace elements, basis of any phytoremediation process. However the amount of pollutants that can be accumulated and detoxified without disrupting the primary ...

Improved methodology and set-point design for diagnosis of model-plant mismatch in control loops using plant-model ratio

Alireza Karimi

Performance of any model-based control scheme depends on the quality of model. When these schemes deliver poor loop performance due to model-plant mismatch (MPM), a detection of the same needs to be in place. A recently introduced plant model ratio (PMR) n ...

Tree root systems competing for soil moisture in a 3D soil–plant model

Gabriele Manoli, Sara Bonetti, Gabriel George Katul

Competition for water among multiple tree rooting systems is investigated using a soil–plant model that accounts for soil moisture dynamics and root water uptake (RWU), whole plant transpiration, and leaf-level photosynthesis. The model is based on a numer ...

On the biomechanics of seedling anchorage

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier

We propose a minimal model for the response of vegetation to pullout constraints at early development stage. We try to capture both the average mechanical properties of the root system and the stochastic component of the uprooting process of seedlings. We ...

Use of Transient Measurements for the Optimization of Steady-State Performance via Modifier Adaptation

Dominique Bonvin, Grégory François

Real-time optimization (RTO) methods use measurements to offset the effect of uncertainty and drive the plant to optimality. RTO schemes differ in the way measurements are incorporated in the optimization framework. Explicit RTO schemes solve a static opti ...

Above and below-ground Salix dynamics in response to river processes

Paolo Perona

Riparian vegetation influences hydraulic and morphodynamic river processes and may contribute to sediment stabilization. In turn, vegetation recruitment and growth on non-cohesive fluvial deposits strongly depends on river hydrology and the ability of root ...

Plant functional types define magnitude of drought response in peatland CO2 exchange

Luca Bragazza, Bjorn Jozef Maria Robroek

Peatlands are important sinks for atmospheric carbon (C), yet the role of plant functional types (PFTs) for C sequestration under climatic perturbations is still unclear. A plant-removal experiment was used to study the importance of vascular PFTs for the ...

On the Use of Second-Order Modifiers for Real-Time Optimization

Dominique Bonvin, Timm Faulwasser

We consider the real-time optimization of static plants and propose a generalized version of the modifier-adaptation strategy that relies on second-order adaptation of the cost and constraint functions. We show that second-order adaptation allows checking ...

Equivalence between Neighboring-Extremal Control and Self-Optimizing Control for the Steady-State Optimization of Dynamical Systems

Dominique Bonvin, Grégory François

The problem of steering a dynamical system toward optimal steady-state performance is considered. For this purpose, a static optimization problem can be formulated and solved. However, because of uncertainty, the optimal steady-state inputs can rarely be a ...
