One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

In order to optimize treatment, it is necessary to closely monitor and manage the patient’s health status by means of ‘precision diagnostics and targeted therapy’. The specialisation combines the techniques and applications of these sensing (monitoring) and stimulation techniques. The field of sensing…

Studies in current archaeological applications of remote sensing and non-invasive prospection methods edited by Hans Kamermans, Martin Gojda and Axel G.

This dissertation examines how we can reconstruct physical activity by looking at variations in the shape of muscle attachment sites ( ‘entheses’) on the human skeleton. It evaluates two post-medieval contexts; rural Middenbeemster and urban Aalst.

On 1 July 2020, Niek Strohmaier defended his thesis 'Making Sense of Business Failure'. The doctoral research was supervised by Prof. J.A.A. Adriaanse en dr. H. Pluut.

1: What is the relative importance of alfa and beta biodiversity in polar ecosystems, and how does intraspecific variation influence this? 2: How can we use remote sensing to determine functional biodiversity (within communities) in polar ecosystems? 3: Temporal and spatial scales of functional biodiversity:…

Many handwritten and illustrated archives contain a wealth of information, but are largely underexplored because they are complex and difficult for computers to decipher. The aim of this project is to develop a digital environment that resolves this challenge and connects heterogeneous archival content…

What workflow of non-destructive techniques provides accurate, valuable data to improve our understanding of Caribbean archaeological landscapes? How were Amerindian settlements configured?

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

What are the biological and biophysical mechanisms that control chemokine gradient sensing and migration of immune, endothelial, and tumour cells in tumour development?

To what extent and in what manner can experimental video be used to reclaim the capacity for telling one’s own story, on one's own terms, speaking in tongues outside the linguistic framework of immune system discourse?

In our lab, we investigate the physics and material properties of low-dimensional systems.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…

Smart digital infrastructures predicated on myriads of sensors distributed in the environment are often rendered as key to contemporary urban security governance to detect risky or suspicious entities before or during a criminal event takes place. At the same time, they often involve surveillance of…

In this research we have studied how teaching graphing formulas by hand (i.e. sketching a graph of a formula) could promote grade 11- and 12-students’ symbol sense.

When is (or becomes) an out-of-body experience a R/S experience? (How) do people make sense of their experiences and is this related to mental health? Which motives do people have to (not) communicate their out-of-body experiences with regular and/or alternative caregivers? And what does it tell us…

Humans perceive the world through different senses: we see, feel, hear, taste and smell. The different senses with which we perceive are multiple channels of information, also known as multimodal. Does this mean that what we perceive can be seen as multimedia?

The manual analysis of remotely-sensed data is a widespread practice in local and regional scale archaeological research, as well as heritage management.

Actin and microtubules form cellular cytoskeletal network, which mediates cell shape, motility and proliferation and are key targets for cancer therapy. Changes in cytoskeletal organization correlate with proliferative capacity and invasiveness of cancer cells. These changes expectedly lead to altered…

Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.

In this project we develop algorithms to automatically detect a particular type of archaeological sites in satellite images of the Alps.

Archaeolandscapes International is an educational and scientific not-for-profit organisation with the objective to promote non-destructive prospecting methods for archaeological investigations.

The Tappino Area Archaeological Project aims to map and analyze ancient settlement patterns and dynamics in a small valley in Central-Southern Italy, in modern Molise (province of Campobasso). The first sites in the area date to the Bronze Age. In the Iron Age to Classical period, it was reportedly…
