Technical note: Gas Chromatography vs. Mid-Infrared Laser Absorption Spectroscopy: A comparison of methods for measuring greenhouse gas fluxes from arable soils Open
For the study of soil-atmosphere exchange of green-house gases, a commonly adopted method is to monitor the change of gas concentrations in closed chambers. Accurate determination of CO2, CH4, and N2O concentrations is therefore essential …

Modeling active layer thickness in permafrost rock walls based on an analytical solution of the heat transport equation, Kitzsteinhorn, Hohe Tauern Range, Austria Open
The active layer thickness (ALT) refers to the seasonal thaw depth of a permafrost body and in high alpine environments represents an essential parameter for natural hazard analysis. The aim of this study is to model ALT based on bedrock t…

Comparison of miniature mid-infrared absorption spectroscopy analyzers with gas chromatography for the quantification of soil greenhouse gas fluxes using the closed chamber method Open
Closed chamber measurements are still the most common approach for measuring the exchange of greenhouse gases (GHG) between soils and the atmosphere in terrestrial ecosystems. Closed chambers can either be employed as static (discrete gas …

An experimental study of two predictive reinforcement learning methods and comparison with model-predictive control Open
Reinforcement learning (RL) has been successfully used in various simulations and computer games. Industry-related applications, such as autonomous mobile robot motion control, are somewhat challenging for RL up to date though. This paper …

Reinforcement learning with guarantees: a review Open
Reinforcement learning is concerned with a generic concept of an agent acting in an environment. From the control theory standpoint, reinforcement learning may be considered as an adaptive optimal control scheme. Despite accumulating evide…
