A stabilizing reinforcement learning approach for sampled systems with partially unknown models

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 34, Issue 18, Page 12389-12412, December 2024.
Abstract Reinforcement learning is commonly associated with training of reward‐maximizing (or cost‐minimizing) agents, in other words, controllers. It can be applied in model‐free or model‐based fashion, using a priori or online collected system data to train involved parametric architectures.

THE DETERMINATION OF HARVEST INDEX OF ’ŠAMPION’ APPLES INTENDED FOR LONG STORAGE

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2011
The harvest date is crucial for the storability of ’Šampion’ apples intended for long storage. Only apples picked at the optimum maturity stage are suitable for storage over 3 months because of better storage potential and organoleptic quality.

Robust Fault Diagnosis by Optimal Input Design for Self-sensing Systems

open access: yes, 2017
This paper presents a methodology for model based robust fault diagnosis and a methodology for input design to obtain optimal diagnosis of faults. The proposed algorithm is suitable for real time implementation. Issues of robustness are addressed for the

Development of a three‐dimensional hydrogeological model for the island of Norderney (Germany) using GemPy

open access: yesGeoscience Data Journal, Volume 11, Issue 3, Page 267-283, July 2024.
A hydrogeological model for the island of Norderney was developed based on borehole data, geological models and interpretation available in the literature. So far, no spatially continuous hydrogeological data was available for the island. The model focuses on describing deposits in which the island’s freshwater lens, which provides drinking water, is ...

Parameters for apple quality - 2 - and the development of the ‘inner quality concept’ 2001-2003 [PDF]

open access: yes, 2004
We found clear correlations between management measures, tree characteristics and fruit characteristics. This means that growers can regulate apple quality during the growing season.

The bay barnacle Amphibalanus improvisus (Darwin, 1854) in the Pleistocene of Europe? A review of Pleistocene Balanidae of northern Central Europe

open access: yesJournal of Quaternary Science, Volume 39, Issue 4, Page 547-565, May 2024.
ABSTRACT The bay barnacle Amphibalanus improvisus (Darwin, 1854) has been found in Northern Germany in brackish marine sediments of the Holsteinian interglacial. Whereas the cause of the contemporary distribution of this species is anthropogenic and there is evidence that it has resulted mainly from shipping, the fossil findings demonstrate that A ...

Storage Ability and Sensory Quality of ‘Reinette Simirenko’ Apples Treated with Ethephon and 1-MCP

open access: yesJournal of Horticultural Research
In order to develop a more effective method for the storage and preservation of excellent taste of late-winter apple ‘Reinette Simirenko’, the effects of preharvest treatment of trees with ethylene-producing ethephon, a three-day delay in postharvest ...

Shoreline slope influences movements of larval lampreys over dewatered substrate

open access: yesAquaculture, Fish and Fisheries, Volume 4, Issue 1, February 2024.
Controlled laboratory study of larval lamprey movement capabilities over dewatered substrates following dewatering. Lamprey habitats, in fine sediments near stream margins, are regularly dewatered. This study helps refine guidance on best management practices to limit impacts to lampreys during dewatering events.
