Dynamic data processing: Recursive least-squares

This book is a follow-up on Adjustment theory. It extends the theory to the case of time-varying parameters with an emphasis on their recursive determination. Least-squares estimation will be the leading principle used. A least-squares solution is said to be recursive when the method of computation enables sequential, rather than batch, processing of the measurement data. The recursive equations enable the updating of parameter estimates for new observations without the need to store all past observations. Methods of recursive least-squares estimation are therefore particularly useful for applications in which the time-varying parameters need to be instantly determined. Important examples of such applications can be found in the fields of real-time kinematic positioning, navigation and guidance, or multivariate time series analysis. The goal of this book is therefore to convey the necessary knowledge to be able to process sequentially collected measurements for the purpose of estimating time-varying parameters. When determining time-varying parameters from sequentially collected measurement data, one can discriminate between three types of estimation problems: filtering, prediction and smoothing. Filtering aims at the determination of current parameter values, while smoothing and prediction aim at the determination of respectively past and future parameter values. The emphasis in this book will be on recursive least-squares filtering. The theory is worked out for the important case of linear(ized) models. The measurement-update and time-update equations of recursive least-squares are discussed in detail. Models with sequentially collected data, but time-invariant parameters are treated first. In this case only the measurement-update equations apply. State-space models for dynamic systems are discussed so as to include time-varying parameters. This includes their linearization and the construction of the state transition matrix. Elements from the theory of random functions are used to describe the propagation laws for linear dynamic systems. The theory is illustrated by means of many worked out examples. They are drawn from applications such as kinematic positioning, satellite orbit determination and inertial navigation.

Tracking student skills real-time through a continuous-variable dynamic Bayesian network

The field of Knowledge Tracing is focused on predicting the success rate of a student for a given skill. Modern methods like Deep Knowledge Tracing provide accurate estimates given enough data, but beingbased on neural networks they struggle to explain how these estimates are formed. More classical methodslike dynamic Bayesian networks can do this, but they cannot give data on the accuracy of their estimatesand often struggle to incorporate new observations in real-time due to their high computational load.This paper presents a novel method, Performance Distribution Tracing (PDT), in which the distribution of the success rate is traced. It uses a dynamic Bayesian network with continuous random variablesas nodes. By tracing the success rate distribution, there is always data available on the accuracy of any success rate estimation. In addition, it makes it possible to combine data from similar/related skills tocome up with a more informed estimate of success rates. This makes it possible to accurately predictexercise success rates, even when an exercise requires a combination of different skills to solve. Andthrough the use of the right conjugate priors, all distributions are available in analytical form, allowing efficient online updates upon new observations. An application to an engineering physics course has shown that the PDT algorithm works well inreal-life settings. Students mainly appreciate the overview given of their learning process as well as the corresponding practice recommendations.

SAWS Dynamic Library

The Sharing Ancient Wisdoms (SAWS) project makes available digital texts from several philosophical traditions, especially texts derived from Arabic, Greek, and Arab-Spanish sources. The texts have been marked up in XML, which the project has made available for download in addition to the XML schemas they used to encode their texts. The project also includes a list of previous workshops, presentations, and publications that have been associated with the project.

Practice Material for Fundamental Courses in Economics

The repository is designed as an open, collaborative collection of digital exercises and supplementary teaching materials for fundamental economics courses. It is structured into subjects that are often found in economics courses. These subjects allow teachers to identify and integrate those exercises they need, based on the topics they are interested in. All exercises are available in English and Dutch. Selected exercises can be implemented through the Grasple platform directly with a free teacher account. Thematic Exercise Sets Basic Microeconomics: Exercises covering cost concepts, elasticity, optimization, and static market theory. Intermediate Microeconomics: Exercises addressing topics such as asymmetric information, principal-agent problems, and externalities. Mathematics in Economics: Materials that bridge mathematical techniques (like differential equations and linear algebra) with economic applications, created in collaboration with the department of Applied Mathematics at TU Delft.

Novel Switchable Glazing Assemblies for Privacy & Glare Control in a Mediterranean Climate

In this recorded presentation from glasstec 2024, Etienne Magri details a research study investigating the combination of PDLC and SPD adaptive glazing technologies to enhance glare control in buildings, using Malta's subtropical climate as a case study. The project involved testing individual and combined laminates within a scale model, evaluating visual appearance and glare using DGP metrics. Results demonstrated that the combined technologies achieved near-complete blackout, effectively eliminating solar glare while maintaining privacy, and successfully transformed static facades into dynamic systems with adjustable transparency. The video was produced by the Open GLASSroom project. Special thanks to Etienne Magri for contributing to the Open GLASSroom OER collection. The creation of these resources has been (partially) funded by the ERASMUS+ grant program of the European Union under grant no. 2022-1-DE01-KA220-HED-000089750.

Managing waste - a teaching game (Teacher version)

Students watch an NPO documentary on the problems and risks of waste processing in the Netherlands, and play a short game that challenges students to identify and capitalize on a key dynamic of these processes. This documentary and game can be the basis of discussion around meanings of waste and the real-life environmental problem it poses for environmental ethics and sustainability in theory and practice.
