van Duijvenbode, J.R. (author), Buxton, M.W.N. (author), Soleymani Shishvan, M. (author)Material attributes (e.g., chemical composition, mineralogy, texture) are identified as the causative source of variations in the behaviour of mineral processing. That makes them suitable to act as key characteristics to characterise and classify material. Therefore, vast quantities of collected data describing material attributes could help...journal article 2020

van Valenberg, W. (author), Klein, S. (author), Vos, F.M. (author), Koolstra, Kirsten (author), van Vliet, L.J. (author), Poot, D.H.J. (author)Quantitative MRI methods that estimate multiple physical parameters simultaneously often require the fitting of a computational complex signal model defined through the Bloch equations. Repeated Bloch simulations can be avoided by matching the measured signal with a precomputed signal dictionary on a discrete parameter grid (i.e. lookup table...journal article 2020

de Ronde, Anouk (author), van Aken, Marja (author), de Poot, Christianne J. (author), de Puit, M. (author)A previous paper published in this journal proposed a model for evaluating the location of fingermarks on two-dimensional items (de Ronde, van Aken, de Puit and de Poot (2019)). In this paper, we apply the proposed model to a dataset consisting of letters to test whether the activity of writing a letter can be distinguished from the...journal article 2020

(author)Purpose: To evaluate the use of magnetic resonance fingerprinting (MRF) for simultaneous quantification of T<sub>1</sub> and T*<sub>2</sub> in a single breath-hold in the kidneys. Methods: The proposed kidney MRF sequence was based on MRF echo-planar imaging. Thirty-five measurements per slice and overall 4 slices were measured in 15.4...journal article 2020

Meijer, Wilko (author)The mobile phone has become an important part of people's lives and which apps are used says a lot about a person. Even though data is encrypted, meta-data of network traffic leaks private information about which apps are being used on mobile devices.Apps can be detected in network traffic using the network fingerprint of an app, which shows...master thesis 2019

Xenakis, Dimitris (author)The performance of an Indoor Positioning System is highly related to the placement of the transmitting nodes that are used as references for the positioning estimations. Within this graduation project, we propose a methodology that can be used to optimize such a deployment and thus, increase the performance of an Indoor Positioning System that a...master thesis 2019

Nguyen, Tuan Anh (author)Billions of wireless devices are interconnected to provide services to many<br/>aspects of life and form The Internet of Things. These devices which are<br/>often battery-powered and energy efficient can benefit greatly from an ac-<br/>curate localisation service that does not consume extra energy. Several loc-<br/>alisation methods have been...master thesis 2019

Restrepo Perez, L. (author)The function and phenotype of a cell is determined by a complex network of interactions between DNA, RNA, proteins and metabolites. Therefore, a comprehensive approach that integrates genomics, transcriptomics, proteomics, and metabolomics is necessary to achieve full understanding of biological processes and disease. Recent technological...doctoral thesis 2019

Resolving Chemical Modifications to a Single Amino Acid within a Peptide Using a Biological NanoporeRestrepo Perez, L. (author), Huang, Gang (author), Bohländer, Peggy R. (author), Worp, N.M. (author), Eelkema, R. (author), Maglia, Giovanni (author), Joo, C. (author), Dekker, C. (author)While DNA sequencing is now amply available, fast, and inexpensive, protein sequencing remains a tremendous challenge. Nanopores may allow for developing a protein sequencer with single-molecule capabilities. As identification of 20 different amino acids currently presents an unsurmountable challenge, fingerprinting schemes are pursued, in...journal article 2019

Sun, Y. (author), Riva, R.E.M. (author), Ditmar, P.G. (author), Rietbroek, Roelof (author)We present a new approach to estimate time variations in J2. Those variations are represented as the sum of contributions from individual sources. This approach uses solely Gravity Recovery And Climate Experiment (GRACE) data and the geoid fingerprints of mass redistributions that take place both at the surface and in the interior of the solid...journal article 2019

Numerous anti-counterfeiting methods based on tagging have been proposed; however, they suffer from three major issues: (1) tagging is applicable only to packages, not tablets directly; (2) end-users, i.e., patients, cannot inspect the tags; (3)...conference paper 2019

(author)Fingerprints are widely used in forensic science for individualization purposes. However, not every fingermark found at a crime scene is suitable for comparison, for instance due to distortion of ridge detail, or when the reference fingerprint is not in the database. To still retrieve information from these fingermarks, several studies have...journal article 2019

Van Eyk, E.D.C. (author), Van Leeuwen, W.J. (author)Crawljax is a crawler, which not only finds states via regular links, but also states that are hidden by JavaScript actions. However, this leads to a gigantic number of states with many duplicates. A near-duplicate detection algorithm can be a solution to limit the number of states found by Crawljax, while crawling the most essential, unique...bachelor thesis 2014
