The recent advent of Artificial Intelligence (AI) and Machine Learning (ML) has piqued the interest of the aerospace industry since it has the potential...

Analysing the North Sea Offshore Energy System in Light of the Energy Transition:: A Case Study Application of the Extended Multi-Level Perspective Framework

The urgent need to address global warming and achieve the 1.5°C target set by the Paris Agreement necessitates an energy transition in Europe, with offshore wind energy in the North Sea playing a vital role. Despite the complexity of the North Sea's offshore energy system, the existing literature lacks a comprehensive study of the entire system,...

Heuristics for a facility location problem with a quadratic objective function

Facility location problems are an important set of problems within the field of optimisation. These problems consider which facilities to open out of a set of possible facilities and how to assign users to the open facilities. Most of the facility location problems studied have a linear objective. In this thesis, we consider a facility location...

Assessing Monitoring and Evaluation Systems in Water and Development Cooperation: a Multi-Actor System Perspective

Water and development projects are development cooperation’s specifically focused on the water sector such as sanitation, drinking water, and water management. In these type of development programmes, governmental or public organizations that manage the water sector in a country are usually involved. These organizations use their financial...

Predicting the upcoming start of large-scale diffusion of radically new high-tech innovations

</p><p class="MsoNormal">Knowing the time point of large-scale diffusion of a radically new high-tech innovation is a highly relevant topic. Companies, researchers, and government institutions can plan their research and development efforts, production, as well as marketing plans according to the predicted time point of...

The effect of storms on fine sediment dynamics in the Dutch Coastal Zone

The North Sea is a heavily used area, with wind parks, shipping routes, fishing, sand mining, and many future constructions planned. The Dutch Coastal Zone, the area of the North Sea containing the Dutch coast, is home to several natural areas, alongside extensive human-built flood defenses. Maintaining balance between these areas requires that...

Future of cities: A research for the optimization of the application of instruments within a municipality to increase sustainability in area development

Currently the world is dealing with a pandemic. The world has stopped, and people are distancing from each other. However, this large crisis is not the only crisis the world is currently dealing with. Climate change is affecting the world drastically since the last century. Our current way of development must stop to deal with this change. This...

Navigating Sand and Waves: On the evolution of sand ripples under combined wave and current conditions

Sand ripples are small (10 cm height) bed forms which occur in the nearshore and surf zone under the impact of both waves and currents. They impact the roughness of the bed used in models of this zone, and contribute to sediment transport. Predictions of their geometry are important to properly model roughness, so correlations between the waves...

Viscosity Perception of Virtual Fluids rendered by a Hand Exoskeleton

—Enabling haptic interaction with non-solid materials, such as liquids or sediments, could expand possibilities for exploration of virtual or remote environments, which would e.g enable training divers and astronauts in simulators. To allow application of natural investigation procedures in such scenarios, haptic interfaces with several degrees...

Novel Method for Mitigating Injectivity Issues during Polymer Flooding at High Salinity Conditions

Synthetic polymers, in the emulsified form, have been utilized for enhanced oil recovery applications by using saline make-up water. However, there are concerns that have been raised about their injectivity. The large entangled polymer chains can clog the pore throats, giving a tendency to cause injectivity reduction. In this study, processing...

Augmented Reality Navigation: The use of Augmented Reality on the bridge to aid navy personnel with safe navigation on future frigates

Assignment With the release of new frigates by 2030, the target is set to operate them with fewer personnel by introducing more complex systems on board. An important human-computer interaction challenge lies in the design of decision support with new technologies, which was explored in my graduation project. Phase 1: Research This project...

With the Head in the Clouds: Daydreaming as a Mindset that facilitates Creative Incubation

This thesis proposes a new method to enhance designers’ creative performance. Applying the unconscious work theory of incubation effects, this thesis proposes that daydreaming during idea incubation could result in more novel and useful ideas by fostering unconscious associative processes. Building on previous findings by Baird et al (2012), who...

A Semi-Analytical Weight Estimation Method for Oval Fuselages in Novel Aircraft Configurations

Research in aircraft design is focusing on novel aircraft configurations in search for a step change in terms of overall transport efficiency. Aircraft design relies heavily on empirical methods, so-called Class 2 methods, to evaluate the performance of a design. Since these methods are based on statistical data their validity is limited when...

Supply Chain Trends impacting the Air Cargo Industry: Assessing Trends and their Impacts in three Industry Sectors

Supply chain management is ever-evolving. The supply chain of large shippers is constantly changing in response to external drivers. But which of these supply chain trends truly impact the air cargo industry and to what magnitude. This research identifies a number of supply chain trends based on an extensive literature review. After that, these...

The Glass Palace. Rethinking the Academic Library: A New Learning Centre for the University of Amsterdam

Het project bestaat uit een onderzoek naar de veranderende rol van de universiteitsbibliotheek en een voorstel voor een nieuwe universiteitsbibliotheek voor de Universiteit van Amsterdam. Het voorstel onderzoekt het potentieel van de bibliotheek als verdediger van een publiek interieur, dat zowel het zich in het publiek afspelen van het...

Financiële haalbaarheid van herbestemming

Financial feasibility of office conversions. Hoge leestand op de kantorenmarkt, afwaarderingen en demografische ontwikkelingen bieden kansen voor projectontwikkelaars; kansen op het gebied van herbestemming van leegstaande kantoren naar woningen. De praktijk wijst echter uit dat onder invloed van gebrek aan inzicht in financiele haalbaarheid,...
