Visualisation of the airflow pattern of exhaled droplets in a classroom

The airborne transmission of SARS-CoV-2 in educational buildings has raised concerns during the current COVID-19 pandemic. In this study, a portable fog generator system was designed and assembled to visualise the airflow pattern of exhaled droplets in a classroom. The system consists of five components: medium, fog generator, buffer, pump, and...

Acceleration Magnification for Visualising Blood Flow Pulsation in the Skin

While millions of people world wide suffer from arterial diseases, such as peripheral arterial disease, there are a limited number of methods that can be used to diagnose and track these diseases which are also easy, quick and non-invasive. <br/><br/>This work focuses on what is needed to improve diagnosing and tracking of peripheral arterial...

Public Transport during coronavirus outbreak: A research of measures taken in Dutch and international PT

In 2019 a virus surfaced in China that would later cause a pandemic: the coronavirus. Across the world measures were taken to reduce the spread of the virus. Public Transport (PT) had a unique position, being both an essential service and a place where the virus can easily be spread. This research investigates the measures taken in PT in the...

Instrumented Skeleton Sled: Focussing on Data Processing and User Interface

This report details the design of an instrumentation system to be used on a skeleton sled. The system will measure several quantities on a skeleton track for the athlete to learn from. This data is stored during the run using several sensors on the sled and processed and visualised immediately afterwards on a mobile device. The project is tailor...

The analysis of three-dimensional embeddings in Virtual Reality

Dimensionality reduction algorithms transform high-dimensional datasets with many attributes per observation into lower-dimensional representations (called embeddings) such that the structure of the dataset is maintained as well as possible. In this research, the use of Virtual Reality (VR) to analyse these embeddings has been evaluated and...

Doplor: Artful warnings towards a more silent Intensive Care

The critical care environment has been witnessed to be one that is unsuitable for sleeping in during day time. Auditory disturbances happen approximately every 12 to 15 minutes, and this is preventing patients to get into their deep sleep during for example the nurse's lunch break. Being able to get into deep sleep has been proven to be very...

Faster Onboarding of Developers in Existing Codebases

When a new software developer joins bunq, a Dutch bank, (s)he will need some time to get familiar with the existing codebase. Preferably, the time necessary for the familiarisation is as short as possible. The faster the developer is up to speed, the faster (s)he can contribute to new features and help solving bugs. This research develops a...

Increasing situational awareness in the golden period of the response phase of sudden-onset disasters by mapping community reachability

In the response phase of sudden-onset natural disasters, information is of crucial importance for relief organisations and their aid workers. Information is necessary for gaining situational awareness in a disaster for effective decision-making in response operations. In my research, an information system is designed that maps the reachability...

Assessing current patterns behind hybrid dams: Demak, Indonesia

The Demak coastal area faces severe erosion problems. The main cause of the erosion of the coastline, which is at some places as high as 1.5 km of land, is the deforestation of the green belt of mangroves for the purpose of building fishponds. This has disturbed the delicate sediment balance in the area drastically. The BioManCO project aims to...

Growing with the grower: Developing a mid segment solution for Priva's horticulture business

Within horticulture, Priva is serving the top of the market with high quality, reliable, but also expensive solutions for process automation. Below this top of the pyramid, there is a big market that has a lot of potential. It is called the mid segment and requires cheaper and more basic solutions for automation. It has a lot of opportunities...

Measure, understand and improve cities: Visualizing pedestrian flows to improve inner-city quality in Delft using GPS-tracking technology

We all have walked on a street when suddenly someone comes over to you asking for directions. Sometimes, people do not know where they are and they do not know how to reach their destination. They are lost. However, people should not depend on others to find their way. The urban fabric should be legible enough to find one’s way. The problem...

Investigation into quantitative visualisation of suffusion

Suffusion is the process whereby seepage water removes fine grains from a soil, which can result in failure of the soil body. This poses a risk for structures founded on soils that are subjected to large hydraulic gradients, such as encountered near hydraulic dams or river levees. Currently, most experimental work on this topic is geared towards...
