Data theory research on the analysis on the multidimensional data

De aankondiging van de Amerikaanse president Donald Trump op 9 maart dat hij ingaat op de uitnodiging voor een topontmoeting met de Noord-Koreaanse leider Kim Jong-un, was een grote verrassing. Analyses in de media variëren van zeer optimistisch tot bijna cynisch negatief. Maar volgens Korea-onderzoek…

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

What are the flows of C&DW (e.g. bricks, concrete, gypsum and wood) in the case study countries ? How to define the specification for each material to be quantified? What indicators should be used to identify the pattern of each C&DW management system? How to interpret the MFA results in relation…

This project uses archaeological, literary and epigraphic evidence to investigate urban development in Roman-period North Africa, compiling this in a GIS-linked database in order to analyse the development of urban settlement spatially over time.

Aim: To develop and enable application of a practical, flexible, user-friendly platform to provide the scientific community with a tool to generate land surface products and its associated uncertainties and exploit these for data-intensive science.

Corruption, integrity (or a lack thereof…) and public values are near omnipresent elements in public administration and politics of all times. Cases of corrupt public officials and politicians continuously emerge. Strangely enough, however, it often remains unknown what actually occurred, how something…

This article 'Shaping the European External Action Service and its post-Lisbon crisis management structures: an assessment of the EU High Representatives’ political leadership' assesses the role, influence and core aspects of the EU High Representatives’ (HR/VPs) “political leadership” in the context…

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

Clinical development of drugs for central nervous system (CNS) disorders has been particularly challenging and still suffers from high attrition rates.

The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

Creating a framework to assess the sustainability of fish farms which will set sustainability standards and give consumers information about the the sustainability and safety of their seafood.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Optimization tasks in practice have multifaceted challenges as they are often black box, subject to multiple equality and inequality constraints and expensive to evaluate.

Real-life processes are characterized by dynamics involving time. Examples are walking, sleeping, disease progress in medical treatment, and events in a workflow.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Self-assembly is an abundant process in nature and is vital to many processes in living organisms.

This proposed research uses ego-documents from visual artists that were not intended for publication to reassess the scholarly debate on the demise of the Russian Avant-garde aesthetic in the twenties and early thirties of the 20th century.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Het idee dat Noord-Koreanen gehersenspoeld zijn en niet in staat om kritisch over hun eigen identiteit te denken, is hardnekkig. Sterker nog, er klopt niets van, zo stelt Koreadeskundige Christopher Green: ‘Noord-Koreanen, net als ieder ander volk, zijn divers in hun meningen en opvattingen.’ Promotie…

The research in this dissertation aims to optimise blood donation processes in the framework of the Dutch national blood bank Sanquin. The primary health risk for blood donors is iron deficiency, which is evaluated based on donors' hemoglobin and ferritin levels.

The research group Politics, Culture and National Identities 1789-present investigates a wide range of national political cultures in Europe and the Americas in the 19th and 20th centuries. Instead of only analyzing high politics (the acts of governments and political parties), the research group focuses…

Indigenous Latin American artifacts have attracted the interest of Europeans since the earliest moment of contact between Europeans and the Indigenous peoples of the Americas.
