van Duijvenbode, J.R. (author)To extract raw materials responsibly and sustainably, the minerals industry has to continuously optimise the mine-to-metal process and requires an entirely different valuation model. Currently, most operational decisions (e.g., ore-waste boundaries, short-term scheduling, blending policies, dispatch decisions) are evaluated using a revenue-based...doctoral thesis 2023

Chemical fingerprinting of volatile organic compounds from asphalt binder for quantitative detectionChang, Xiwen (author), Long, Yongshuang (author), Wang, C. (author), Xiao, Yue (author)Asphalt material is an irreplaceable material in road construction. However, it releases VOCs (Volatile Organic Compounds), which do cause pollution to the surrounding environment, during its full life cycle, especially in high-temperature paving stage and summer service time. Asphalt VOCs release mechanism and effective emission reduction...journal article 2023

Güdek, Ahmet (author)Since the introduction of networking protocols for Low-power and Lossy Networks (LLN), many implementations have been created in the form of (real-time) Operating Systems (OS), simplifying their usage and making the technology more widely available. The low cost and low complexity of LLNs allow for large-scaled wireless sensor deployments,...master thesis 2022

Triantafyllou, Giorgos (author)Nowadays, humans rely in technology more and more when it comes to navigation and localisation and in many aspects of life as well. While most concepts related to localisation and navigation of outdoors environments are already well derived from various researches and softwares, the indoor environment remains a significantly unexplored area....master thesis 2022

Louwen, Anton (author)Radio frequency fingerprinting has been identified as a method to increase integrity in aircraft surveillance while retaining its openness. One way to uniquely determine transmitting devices is to distill the device its radio frequency (RF) fingerprint by looking at the physical features of the message signal it transmits. This physical layer...master thesis 2022

Filius, M. (author)Proteins are the workhorses of the cell, as such, they form the basis of all living systems. In order to fully understand biological processes, the ability to identify and quantify the proteins in cells is crucial. Identification can be achieved by determining the amino acid sequence of proteins, since this sequence is unique for each protein....doctoral thesis 2022

Nunez-Gonzalez, L. (author), Nagtegaal, M.A. (author), Poot, D.H.J. (author), de Bresser, J. (author), van Osch, M. J.P. (author), Hernandez-Tamames, J.A. (author), Vos, F.M. (author)MR fingerprinting (MRF) is a promising method for quantitative characterization of tissues. Often, voxel-wise measurements are made, assuming a single tissue-type per voxel. Alternatively, the Sparsity Promoting Iterative Joint Non-negative least squares Multi-Component MRF method (SPIJN-MRF) facilitates tissue parameter estimation for...journal article 2022

Bailey, Melanie J. (author), de Puit, M. (author), Romolo, Francesco Saverio (author)Surface analysis techniques have rapidly evolved in the last decade. Some of these are already routinely used in forensics, such as for the detection of gunshot residue or for glass analysis. Some surface analysis approaches are attractive for their portability to the crime scene. Others can be very helpful in forensic laboratories owing to...review 2022

Nagtegaal, M.A. (author), Hartsema, Emiel (author), Koolstra, Kirsten (author), Vos, F.M. (author)Purpose: To develop an efficient algorithm for multicomponent MR fingerprinting (MC-MRF) reconstructions directly from highly undersampled data without making prior assumptions about tissue relaxation times and expected number of tissues. Methods: The proposed method reconstructs MC-MRF maps from highly undersampled data by iteratively...journal article 2022

van Duijvenbode, J.R. (author), Cloete, Louis M. (author), Soleymani Shishvan, M. (author), Buxton, M.W.N. (author)Geochemical and mineralogical datasets from Tropicana Gold Mine, Australia, have been used to define Au-mineralised fingerprints. VNIR-SWIR spectral data were represented by four normalised wavelength regions and were clustered to form spectral classes. Sequentially, these spectral class proportions within a block and co-located pXRF data...journal article 2022

Graafmans, Roy (author)Virtual private networks are often used to secure communication between two hosts and preserve privacy by tunneling all traffic over a single encrypted channel. Previous work has already shown that metadata of different secured channels can be used to fingerprint various kinds of information. In this work, we will dive into the encrypted tunnels...master thesis 2021

Molenkamp, Michaël (author)Many devices currently connect to the internet. Some are pretty well secured, while others lack security due to bugs or other vulnerabilities. A scanner searches for available services on the internet or computer host using standard network protocols. An adversary uses a scanner to search for leaks in security. However, scanners encode their...master thesis 2021
