Visualizing the pH profile inside the catholyte of a CO2 electrolysis cell

CO2 electrolysis to form CO with the use of electricity from renewable sources is a promising technique in closing the carbon cycle. Via the electrochemical reduction CO2 can be converted into different hydrocarbon products. These value-added products are for example CO, HCOOH, CH3OH or C2H4. The direct electrochemical route of CO2 reduction is...

Back to the Commons: Introducing Regenerative Agricultural Networks in Northwestern Europe

For the last decades, technologies, new agricultural trade policies, environmental restrictions, high pressure through economic competition in combination with a sharp competition of land lead to the development of intensive farming. As a result, patchy landscapes have been replaced by monofunctional, homogeneous agricultural landscapes that...

Image-based Video Search Engine: Data Compression and Nearest Neighbour Search

One of the main problems with Instance-level Image Retrieval in video data is that for longer query videos or large amount of image queries, comparing all of the query images to every extracted frame is time-inefficient. This thesis aims to solve this problem by implementing Nearest Neighbour Search (NNS) algorithms and data compression methods,...

Characterization and Mitigation of High-Confidence Errors Through the Use of Human-In-The-Loop Methods: Domain Expert Driven Approach to Model Development

In the use of Machine Learning systems, attaining the trust of those that are the end-users can often be difficult. Many of the current state-of-the-art systems operate as Black-Boxes. Errors produced by these Black-Box systems, without further explanation as to why these decisions were made, will deteriorate trust. This effect is especially...

A Distributed Public Key Infrastructure for the IoT

The role of Internet of Things (IoT) devices is becoming larger in our day-to-day life. More and more, devices are used to help with simple tasks in our lives. Little computers are installed in a large variety of consumer products and are often connected to the internet. The large increase of these “resource-constrained” devices that are...

CryptoPIX: The Blockchain Based Daily Pixel Art Competition

During the project the team aimed to make a decentralized web based game on the blockchain, that is fun to play and is indistinguishable from traditional centralized games. To accomplish this it was chosen to create the game on the EOS blockchain platform. The EOS blockchain platform features great improvements upon older more popular platforms...

Non-intrusive patient monitoring for pressure ulcer prevention: Group F - Test Group

Problem Definition<br/>This bachelor final project was an assignment given by the start up Momo Medical named: "Improving health care with technology". This project was to use their existing technology and ideas to create a system to prevent pressure ulcers. Pressure ulcer are the medical condition that happens when a patient is left too long in...

Earth frozen orbits: Design, injection and stability

A frozen orbit is an orbit chosen such that the effect of perturbations on (a combination of) the mean orbital elements is minimized. The concept first appeared in literature in 1978, and was applied that same year to the Seasat mission. This altimetry mission featured strict requirements on the accuracy of the altitude of the satellite above...

Dynamisch Haringvliet: Waar land en water ontmoeten

Door het creëren van een bufferzone langs het Haringvliet ontstaat een dynamisch landschap. Dit landschap is adaptief aan ontwikkelingen in de toekomst wat betreft het openen van de Haringvlietsluizen (zoet-zout gradiënt, getij) en de toenemende hoeveelheden water vanuit de Noordzee en het Haringvliet. Het ontwerp is benaderd vanuit 4...

De Houthaven markt: Het verleden als inspiratie voor de herontwikkeling van de Houthavens

De Houthavens is een voormalig havengebied in Amsterdam west die zijn functie verloren heeft. Herontwikkeling is nodig, maar hoe moet een gebied getransformeerd worden waarvan de cultuur historie verloren is gegaan? Dit stedenbouwkundig en architectonisch ontwerp geeft een antwoord op deze vraag. Door het havengebied uitvoerig te analyseren zijn...

Optimalisatie van een afvoerleiding van een zijdelingse overlaat bij een stuwmeer

Het hoofdontwerp in de afstudeerrichting irrigatie omvat het ontwerpen van een reservoirdam met bijkomende werken ten behoeve van bevloeiing van landbouwgronden. Een van de voorzieningen, die bij een stuwmeer nodig zijn, is een overlaat om het waterpeil in het reservoir beneden de kruin van de dam te houden. De overlaat kan op verschillende...
