Introduction to Stochastic Hydrology

Hydrologic systems are both complex and extremely heterogeneous in time and space. As hydrological models are simplified versions of reality, their predictions are by definition subject to uncertainty. The field of stochastic hydrology focuses on quantifying this uncertainty along with prediction. This book aims to present an overview of the field of stochastic hydrology at an introductory level. A wide range of topics and methods will be treated, while each topic and method is only treated at a basic level: descriptive statistics; probability and random variables; hydrological statistics and extremes; random functions; time series analysis; geostatistics; forward stochastic modeling; and state prediction and Kalman filtering. The book can be used for a 10-15-week course at third-year undergraduate or first-year graduate level.

Workshop Recognition and Rewards

The interactive workshop Recognition and Rewards focuses on the impact of recognition and rewards on the choices made within research regarding Open Science principles. It is notable that, in the current system, Open Science-related tasks receive less recognition and appreciation than 'traditional' research tasks. The workshop demonstrates how the societal impact of research can change through a cultural shift regarding recognition and rewards for Open Science tasks.

ACA-bot

ACA-bot is an engaging chatbot designed for Automated Conversational Assessment (ACA). Drawing inspiration from traditional oral exams, this text-based conversational agent transforms assessment into a dynamic learning experience. It supports both formative and summative evaluation by offering students personalised feedback and guidance at every step of their learning journey. The first ACA-bot prototype focuses on assessing students’ understanding of basic statistical concepts, but its flexible design allows for easy adaptation to a wide range of subjects and learning contexts. Through interactive dialogue, students can practise explaining ideas clearly under exam-like conditions, apply their knowledge to new and challenging questions, and refine their reasoning as they respond to follow-up prompts. They gain valuable insights into their own understanding, identify areas for improvement, and gradually build confidence for both oral and written assessments. For educators, ACA-bot offers a powerful way to scale oral examinations and enhance formative assessment without increasing workload. It automates parts of the assessment process, provides structured and actionable insights into student performance, and opens the door to more personal, interactive feedback at scale. By combining the strengths of conversational AI and educational assessment, ACA-bot turns evaluation into a collaborative, insightful process. It empowers students to think aloud, reason more effectively, and grow, while giving educators a smarter, more innovative way to understand and support learning. ACA-bot is een slimme en inspirerende chatbot die onderwijs en Artificial Intelligence samenbrengt. Geïnspireerd door het klassieke mondelinge examen tilt deze tekstgebaseerde gespreksagent Automated Conversational Assessment naar een nieuw niveau. Studenten krijgen via natuurlijke gesprekken directe, persoonlijke feedback en begeleiding, waardoor leren en toetsen samenvloeien in één boeiende ervaring. Het prototype van ACA-bot is ontwikkeld om kennis over statistiek te beoordelen, maar dankzij het flexibele ontwerp kan het systeem eenvoudig worden aangepast aan andere vakgebieden en toepassingen. Tijdens interactieve dialogen leren studenten helder uitleg geven, hun kennis toepassen op nieuwe vragen en hun redenering aanscherpen. Ze ontdekken waar hun begrip nog verdiept kan worden en groeien zichtbaar in zelfvertrouwen — waardevolle voorbereiding op zowel mondelinge als schriftelijke examens. Ook voor docenten biedt ACA-bot een slimme oplossing. Het maakt mondelinge toetsing schaalbaar, ondersteunt formatieve beoordeling via gesprek, en vermindert de werkdruk door delen van het beoordelingsproces te automatiseren. Bovendien geeft het gestructureerde inzichten in de voortgang en denkwijze van studenten, waardoor elke dialoog bijdraagt aan beter onderwijs. ACA-bot laat zien hoe Automated Conversational Assessment het leren persoonlijker, interactiever en effectiever maakt. Studenten denken hardop, verkennen hun eigen begrip, en verbeteren met vertrouwen — terwijl docenten op een innovatieve, datagedreven manier inzicht krijgen in hoe kennis werkelijk wordt begrepen.

The Digital Age: What about Human Values? | Radboud Reflects Lecture with Tamar Sharon

How can we make room for the human dimension in a world that is becoming increasingly digitized? Digitization seems to be the solution to everything: problems in education, healthcare, and even the justice system. How can we continue to make room for other essential values such as creativity, empathy, caring for one another, privacy, cooperation, or the right to a fair trial? Listen to philosopher Tamar Sharon, who argues that digitization has become our new framework for thinking. She points out the dangers of this: is human dignity being compromised? The Digital Age: What about Human Values? | Silent-interview with political philosopher Tamar Sharon Denkwerk 2026 | Saturday 7 March 2026 | De Lindenberg, Nijmegen Radboud Reflects and Faculty of Philosophy, Theology and Religious Studies

Lateral Load Resistance of Glass Pane According to EN 16612

In this video, Martina Eliášová introduces the European standard EN 16612 for determining the lateral load resistance of glass panes used as infill panels in windows and facades. The standard provides design procedures for monolithic, laminated, or insulated glass that is simply supported around its edges and subjected to uniform loads like wind or thermal stress. The design follows the limit state method, which includes checking the Ultimate Limit State (to prevent collapse by ensuring design tensile stress is less than the design glass strength) and the Serviceability Limit State (to control deformation). A key aspect is the use of partial safety factors, where design loads are increased and material strengths are reduced. The design bending strength of glass is significantly influenced by the load duration (through the Kmod factor), the edge condition (Ke factor), and the glass surface profile (Ksp factor), with specific characteristic strength values and adjustment factors provided for different glass types like annealed and pre-stressed glass. The video was produced by the Open GLASSroom project. Special thanks to Martina Eliášová for contributing to the Open GLASSroom OER collection.

Fracture Mechanics Fundamentals

In this video, Daniel Trias Mansilla explains the core principles of fracture mechanics, which provides an alternative to traditional stress analysis by accounting for the inherent cracks and defects in real materials. The field introduces two main criteria for predicting failure. The first is an energy-based approach, using the energy release rate (G), which measures the energy available to propagate a crack. The second is a stress-based approach, using the stress intensity factor (K), which characterizes the intense stress field near a crack tip. Fracture occurs when either of these values reaches a critical threshold (Gc or Kc), which are material properties known as fracture toughness. These concepts allow engineers to predict failure in flawed components more accurately than traditional methods. The video was produced by the Open GLASSroom project.

Thermo-optical Properties

In this video, Francesco Fiorito, from the Polytechnic University of Bari, explains how glass interacts with solar radiation. When sunlight hits a window, some energy is transmitted inside, some is reflected, and some is absorbed. Two key values define a glass's performance: the Solar Factor (or g-value), which measures total heat gain, and the Visible Light Transmittance (VLT), which measures how much light passes through. While clear glass has high values for both, it can cause overheating. Tinted glass reduces heat gain but also makes interiors darker. Selective glass uses special coatings to block heat (a low g-value) while still allowing plenty of light (a high VLT). Other coatings, like low-emissivity (low-e), help with thermal insulation. The video concludes that selecting the right glass is essential for energy efficiency and comfort in buildings. The video was produced by the Open GLASSroom project.
