Adaptive Strategies for Reducing Yield‐Scaled Nitrate Leaching in the US Midwest

open access: yesEarth's Future, Volume 13, Issue 10, October 2025.
Abstract Fertilizer use enhances crop yields but exacerbates nitrate leaching, threatening water quality in farming systems. This study optimizes nitrogen fertilization strategies by integrating numerical modeling and machine learning to balance corn yield and nitrate leaching in the US Midwest, 1979–2100. We evaluate the economic optimum nitrogen rate

Selection of Appropriate Criteria for Optimization of Ventilation Element for Protective Clothing Using a Numerical Approach

open access: yesComputation
While there are multiple methods to ventilate protective clothing, there is still room for improvement. In our research, we are using ventilation elements that are positioned at the ventilation holes in the air space between the body and clothing.

Elementary Students' Metacognitive Knowledge of Epistemic Criteria

open access: yesJournal of Research in Science Teaching, Volume 62, Issue 7, Page 1721-1742, September 2025.
ABSTRACT Scientific modeling is a core practice of scientific inquiry. Students' engagement in modeling can be enhanced by attending to epistemic criteria, which in science are standards used to evaluate the validity and accuracy of scientific models. While prior research has focused on students' development and use of epistemic criteria in scientific ...

A Domain‐Independent, Extensible Framework for Generators of Training Game Activities on Declarative Knowledge

open access: yesJournal of Computer Assisted Learning, Volume 41, Issue 4, August 2025.
ABSTRACT Background Training the memorization of declarative knowledge requires the repetitive presentation of various forms of factual questions to learners. Educational games designed for this purpose should offer activities that are both tailored to individual learners and varied to prevent boredom.

A Metamodel for Enterprise Architecture [PDF]

open access: yes, 2010
The paper presents an evolved metamodel that has its origins in GERAM 1.6.3 but takes into considerations the needs of evolution of EA standards, including ISO 15704:2000 and ISO 42010:2000 - both currently under review.

Global sensitivity analysis for the boundary control of an open channel

open access: yes, 2014
The goal of this paper is to solve the global sensitivity analysis for a particular control problem. More precisely, the boundary control problem of an open-water channel is considered, where the boundary conditions are defined by the position of a down ...

Enhancing Smart Tourism With Chatbots: Focus on the Metamodel of Domain‐Specific Language and Emerging Technologies

open access: yesExpert Systems, Volume 42, Issue 7, July 2025.
ABSTRACT The tourism sector is adopting smart solutions to offer visitors more personalised and sustainable experiences. By leveraging urban infrastructure and new technologies, tourist destinations aim to enhance the interaction between travellers and their environment. Artificial intelligence (AI) and natural language processing (NLP) play a key role

Model evolution and system evolution

open access: yesJournal of Computer Science and Technology, 2000
In this paper we define an evolution mechanism with formal semantics using the metamodeling methodology [Geisler et al.98] based on dynamic logic. A remarkable feature of the metamodeling methodology is the ability to define the relation of intentional ...
