Spring, H. (author)The study of crystalline solids and condensed matter physics at large concerns itself with the new behaviors and phases of matter exhibited by elementary particles, atoms, and molecules by virtue of being assembled into a structure. These phases arise from complex microscopic behaviors, which makes it is difficult to establish rigorous...doctoral thesis 2023

Wen, Weijie (author), Lyu, Rui (author), Li, Botong (author), Cao, Hong (author), Yu, Jiali (author), Li, Bin (author), Popov, M. (author)For the black start-up of DC micro-grids, three-phase charging resistors are required to limit the uncontrollable surge current. The main drawback of this start-up method is the difficulty in determining the appropriate resistance value to achieve a rapid start-up and limit the surge current with the change of grid parameters. To address this...journal article 2023

Badhrudeen, Mohamed (author), Derrible, Sybil (author), Verma, T. (author), Kermanshah, Amirhassan (author), Furno, Angelo (author)This article presents a method to uncover universal patterns and similarities in the urban road networks of the 80 most populated cities in the world. To that end, we used degree distribution, link length distribution, and intersection angle distribution as topological and geometric properties of road networks. Moreover, we used ISOMAP, a...journal article 2022

Turan, E. (author), Speretta, S. (author), Gill, E.K.A. (author)This study provides a performance analysis of radiometric autonomous navigation for the lunar satellite network topologies formed by three spacecraft at various orbits. This work is built on the Linked Autonomous Interplanetary Satellite Orbit Navigation (LiAISON) method and uses mesh (distributed) and centralized (star) network topologies. The...other 2022

Barczyk, R.T. (author), Parappurath, Nikhil (author), Arora, S. (author), Bauer, T.A. (author), Kuipers, L. (author), Verhagen, Ewold (author)The introduction of topological concepts to the design of photonic crystal cavities holds great promise for applications in integrated photonics due to the prospect of topological protection. This study examines the signatures of topological light confinement in the leakage radiation of 2D topological photonic crystal cavities. The cavities are...journal article 2022

de Hoop, S. (author), Voskov, D.V. (author), Bertotti, G. (author), Barnhoorn, A. (author)Fracture networks are abundant in subsurface applications (e.g., geothermal energy production, CO<sub>2</sub> sequestration). Fractured reservoirs often have a very complex structure, making modeling flow and transport in such networks slow and unstable. Consequently, this limits our ability to perform uncertainty quantification and increases...journal article 2022

Pradhan, B. (author), Barth, R. (author), Kim, E. (author), van Laar, T. (author), Yang, W.W.W. (author), Ryu, J.K. (author), van der Torre, J. (author), Peters, Jan Michael (author), Dekker, C. (author)Ring-shaped structural maintenance of chromosomes (SMC) complexes like condensin and cohesin extrude loops of DNA. It remains, however, unclear how they can extrude DNA loops in chromatin that is bound with proteins. Here, we use in vitro single-molecule visualization to show that nucleosomes, RNA polymerase, and dCas9 pose virtually no...journal article 2022

Erdmanis, J. (author)The microscopic theory of superconductivity proposed by John Bardeen, Leon Cooper, and John Robert Schrieffer has been a vital milestone of condensed matter physics and the basis of development of new quantum technologies. It explained the superconductivity as an emergent phenomenon arising from weak phonon-mediated attraction of individual...doctoral thesis 2021

Gorny, R.A. (author)A Flat Theory presents a first step toward a yet-to-be-completed, larger project: a genealogy of apartments. While centering on the historical formation of apartments, it does not offer a straight-forward history of apartments or flats. Rather, as a contribution to a wider history of the present, it draws together the first synthetic study of...doctoral thesis 2021

Vitalis, S. (author), Arroyo Ohori, G.A.K. (author), Stoter, J.E. (author)3D city models are being extensively used in applications such as evacuation scenarios and energy consumption estimation. The main standard for 3D city models is the CityGML data model which can be encoded through the CityJSON data format. CityGML and CityJSON use polygonal modelling in order to represent geometries. True topological data...journal article 2019

Beukman, A.J.A. (author)This thesis includes two research directions both aim to discover a building block for topological quantum computing. First, in Chapter 3, a novel setup is designed, built, and tested, that can electrostatically gate a material without endangering the materials pristine quality. The setup was designed with the goal to reveal non-Abelian...doctoral thesis 2016

van Westering, W.H.P. (author), Van Der Meulen, Michiel (author), Bosma, Wieb (author)This paper applies the distribution network reconfiguration problem to existing networks. The medium voltage distribution network of the Dutch DSO Alliander is operated using a radial topology. By optimizing this topology it is possible to reduce the energy losses caused by the cable impedances. Various solutions algorithms have been compared...conference paper 2016

Liu, L. (author), Xu, W. (author), Penard, W. (author), Zlatanova, S. (author)In this paper, we leverage spatial model to process indoor localization results and then improve the track consisting of measured locations. We elaborate different parts of spatial model such as geometry, topology and semantics, and then present how they contribute to the processing of indoor tracks. The initial results of our experiment reveal...conference paper 2015

(author)The three dimensional conformation of the genome in the cell nucleus influences important biological processes such as gene expression regulation. Recent studies have shown a strong correlation between chromatin interactions and gene co-expression. However, predicting gene co-expression from frequent long-range chromatin interactions remains...journal article 2015

Biljecki, F. (author), Ledoux, H. (author), Stoter, J.E. (author)The CityGML standard enables the modelling of some topological relationships, and the representation in multiple levels of detail (LODs). However, both concepts are rarely utilised in reality. In this paper we investigate the linking of corresponding geometric features across multiple representations. We describe the possible topological cases,...conference paper 2014

Thompson, R.J. (author)A Digital Cadastral Data Base (DCDB) is a big investment for a jurisdiction tasked with the administration of land boundaries. In the past, the development of such a database produced no real pay-back on investment until many years, and millions of dollars had been committed. The Land Administration Domain Model (LADM) (ISO-TC211 2012) provides...conference paper 2013

(author)In this paper the design and development of a prototype 3D Cadastral system will be presented. The key aspects of this system are that the model is based on Land Administration Domain Model (LADM) and that the spatial profile is based on a full 3D topological structure. The prototype development starts with profiling the LADM (selecting relevant...conference paper 2011

Ledoux, H. (author), Meijers, B.M. (author)Planar partitions—full tessellations of the plane into non-overlapping polygons—are frequently used in GIS to model concepts such as land cover, cadastral parcels or administrative boundaries. Since in practice planar partitions are often stored as a set of individual objects (polygons) to which attributes are attached (e.g. stored with a...conference paper 2010

Thompson, R.J. (author), Van Oosterom, P.J.M. (author)In order to be able to draw inferences about real world phenomena from a representation expressed in a digital computer, it is essential that the representation should have a rigorously correct algebraic structure. It is also desirable that the underlying algebra be familiar, and provide a close modelling of those phenomena. The fundamental...journal article 2009
