Managers increasingly seek ways to explore insights from data for business improvements and innovation. Data Analytics (DA) platforms hold promise for businesses, especially small businesses that cannot afford tailor-made proprietary analytics services. DA platforms offer generic analytics features to a pool of businesses, saving costs and...

Embedded load-bearing laminated glass connections have gained popularity in recent years due to their mechanical performance and aesthetic appeal. However, there is a paucity of data on their structural behaviour across a range of temperatures that may arise in building applications and there is also no simplified mechanics-based model for...

A new model is proposed for the consolidation of hybrid textiles, in which air entrapment and dissolution are considered. One of the key parameters is tow permeability, which is described by the analytical model of Gebart and validated at very high fibre volume fractions by direct tow permeability measurement. The model also takes into...

Context. In a Keplerian system, a large number of bodies orbit a central mass. Accretion disks, protoplanetary disks, asteroid belts, and planetary rings are examples. Simulations of these systems require algorithms that are computationally efficient. The inclusion of collisions in the simulations is challenging but important. Aims. We intend...

Climate agreement goals set by the Dutch government increase the urge to reduce our greenhouse gases. To fulfil these goals on a residential level a reduction of the emission of carbon which is produced during household demand and transportation (commute) is required. On a residential level, the amount of photovoltaic systems (PV) and electric...

Sokołowski, Piotr (author)
State-of-the-art tilt-rotor flight mechanics models appear to be inadequate in predicting the flight dynamics behavior across the entire flight envelope due to a lack of experimental data suggesting the need for more generic models. This paper presents a middle ground between model flexibility (genericity) and accuracy. For this purpose a...

In this work, we present VisuaLayered, the implementation of a combined analysis workflow for pigment identification. VisuaLayered is an integrated, interactive system that focuses on the combined visual analysis of Macro X-Ray Fluorescence (MA-XRF) and Reflectance Imaging Spectroscopy (RIS) data.<br/><br/>Analysing paintings for pigment...

Cold-bent insulating glass units (IGU) have the potential to be one of the answers to current needs and wishes of modern and sustainable architecture. Curved glass is stiffer against out-of-plane loads and therefore the structural behaviour of cold-bent IGU’s is different compared to flat IGU’s. Structural behaviour of flat glass in buildings is...

Investigations on unreinforced masonry (URM) walls subjected to natural hazards, such as earthquakes and wind loads, identify the out-of-plane (OOP) failure as one of the most common failure mechanisms. Concerning the OOP failure, two types of failure mechanisms can be distinguished in URM walls: one-way bending in which lateral edges of walls...

Big data analytics (BDA) and supply chain resilience are both present and important topics, but research on the relation between the subjects is limited. This also holds for the translation of the subject for a specific industry. This research therefore addresses this relation and translates it to a comprehensive partial resilience assessment...

The aim of this thesis was to test the efficiency in practice of an analytical propagator with collision detection for <i>N</i>-body Keplerian systems. This can be used to simulate the evolution of a protoplanetary disk, which gives insight into how planetary systems form. The analytic propagator calculates collisions one by one, while a...

The transverse flute can be studied on many aspects. In this thesis the sound waves that can be generated inside the flute are studied on their shape and frequencies. To achieve this, two mathematical models of the sound waves inside a flute are developed. To develop these models, solutions to the second dimensional wave equation are calculated...

This research is about which geometry of FRP slabs is the most optimal, in terms of costs, to use for a given load and boundary conditions taking the occurring uplift bolt forces into account. The first part of the report focuses on the calculation of the uplift forces in the bolted connections caused by the moving loads. For this, first a...

The demand for renewable energies is rising due to climate goals and high oil prices. Not only the established renewable sources like wind and solar are interesting to exploit. There is a vast amount of energy stored in the world’s oceans. To harvest this energy, one needs a Wave Energy Converter (WEC). There<br/>are already some prototype WECs...

Flood gates form an essential part of many flood defence systems in coastal areas. During storm events, these gates are subjected to extreme loads from various sources. This dissertation addresses the dynamic behaviour of flood gates induced by wave impacts. A semi-analytical fluid-structure interaction model is developed to predict vertical...

The Haringvlietbrug, which was delivered in 1964 and connects the island of Goeree-Overflakkee to the Dutch mainland, approaches the end of its lifetime. Rijkswaterstaat and Witteveen+Bos investigate the potential use of vibration-based structural health monitoring (SHM) to track deterioration. In vibration-based SHM, a change in the structure’s...

The predestined energy transition will induce major changes in the energy system. As demand for electricity is expected to rise, the electricity grid expansion by the DSO is viewed as an essential aspect in the transition. It is argued that the DSO currently face two major challenges; an increased workload, and ageing and scarcity of personnel....

For a global quantum communication network, we need to have long distance links over which we can distribute entangled photon pairs. Due to exponential losses, using optical fibres alone is unfeasible. Quantum repeaters extend the range of quantum networks, but intercontinental links are still unfeasible. Because of this, research has gone...

Efficient and affordable solar energy is essential for reducing greenhouse gas emissions and achieving climate neutrality. Large-scale offshore floating photovoltaics (LOFPV) provide creative opportunities for clean and cost-effective renewable energy production close to populated areas. They are composed of solar modules, a membrane platform,...

Reaction wheels are often the main contributor to microvibrations on satellites. These vibrations are a source of pointing errors and therefore need to be limited as much as possible. The miniaturization trend in the space industry and universities fostered the production of very small reaction wheels, suited to Cubesat and PocketQube scales. A...
