Dekking, F.M. (author), Simon, Károly (author), Székely, Balázs (author), Szekeres, Nóra (author)Can we find a self-similar set on the line with positive Lebesgue measure and empty interior? Currently, we do not have the answer for this question for deterministic self-similar sets. In this paper we answer this question negatively for random self-similar sets which are defined with the construction introduced in the paper by Jordan et al. ...journal article 2024

(author), Fedorova, Natalia D. (author), Grigoriev, S. V. (author)The organization of chromatin in the nuclei of rat lymphocyte was studied by time-of-flight spin-echo small-angle neutron scattering (ToF-SESANS). The procedures of the measurements in ToF and monochromatic SESANS modes were compared. It is shown that the sensitivity of the ToF method is significantly higher than that of the monochromatic mode....journal article 2023

Kekkonen, H.N. (author), Lassas, Matti (author), Saksman, Eero (author), Siltanen, Samuli (author)We propose alternatives to Bayesian prior distributions that are frequently used in the study of inverse problems. Our aim is to construct priors that have similar good edge-preserving properties as total variation or Mumford-Shah priors but correspond to well-defined infinite-dimensional random variables, and can be approximated by finite...journal article 2023

Accou, B.O.R. (author), Reniers, G.L.L.M.E. (author)Despite the systems approach to accident analysis being the dominant research paradigm and the concept of SMS being introduced in high-risk industries already for several years, accident investigation practice is still poor in analysing the basic elements that compose a safety management system (SMS) and in embracing system theory. In search of...journal article 2022

Spencer, K. L. (author), Wheatland, J. A. (author), Carr, S. J. (author), Manning, A. J. (author), Bushby, A. J. (author), Gu, C. (author), Botto, L. (author), Lawrence, T. (author)Natural sediment flocs are fragile and highly heterogeneous aggregates of biogenic and minerogenic material typically with high porosity and low density. In aquatic environments dominated by fine, cohesive or mixed sediments they can dominate suspended sediment flux. Consequently, monitoring and modelling the behaviour, transport and...journal article 2022

Barciela Rial, M. (author), Vardon, P.J. (author), van Kessel, Thijs (author), Griffioen, Jasper (author), Winterwerp, J.C. (author)Progressively, more dredged sediments are being reused for engineering projects. For example, the Marker Wadden is a new wetland constructed in lake Markermeer, the Netherlands, with dredged cohesive sediments originating from the bed of the lake. Such dredged sediments are often dominated by cohesive sediment particles with varying amounts of...journal article 2022

Zheng, Yonglai (author), Wen, Yuan (author), Pan, Tanbo (author), Liu, Yongcheng (author), Zhou, Yujue (author), Li, Ruizhi (author), Zhou, Y. (author)This study investigated the relationship between the acoustic emission (AE) signals parameter sequence fractal characteristics and the damage evolution information of corroded reinforced concrete (RC) beams under four-point bending. Strength deterioration behavior and AE data can be obtained by coupling the four-point bending test and the AE...journal article 2022

Lipschütz, Henriette (author), Reitebuch, Ulrich (author), Skrodzki, M. (author), Polthier, Konrad (author)Various computer simulations regarding, e.g. the weather or structural mechanics, solve complex problems on a two-dimensional domain. They mostly do so by splitting the input domain into a finite set of smaller and simpler elements on which the simulation can be run fast and efficiently. This process of splitting can be automatized by using...journal article 2022

Lakshminarayanan, Vasudevan (author), Chockalingam, Cindhuja (author), Mendes, E. (author), van Esch, J.H. (author)Properties such as shear modulus, gelation time, structure of supramolecular hydrogels are strongly dependent on self-assembly, gelation triggering mechanism and processes used to form the gel. In our work we extend reported rheology analysis methodologies to pH-triggered supramolecular gels to understand structural insight using a model...journal article 2021

Shakeel, A. (author), MacIver, Michael R. (author), van Kan, Paul J.M. (author), Kirichek, Alex (author), Chassagne, C. (author)Natural fine-grained suspensions usually exhibit a complex rheological fingerprint – in particular a two-step yielding phenomenon – due to the presence of mineral clay particles and organic matter (often found in a flocculated state). These rheological properties may vary considerably from one location to another due to the differences in mud...journal article 2021

Alinaghi, Pouriya (author)In the well-known process of the turbine design, turbulence intensity (TI) plays a vital role in prediction of the power output and loads on the turbine's structure. TI is believed to be an important statistical parameter of the wind speed that can be extracted from the signals recorded by the dedicated sensors in the wind energy area. Despite...student report 2020

Suvarna, Pranav (author)Convective heat transfer finds applications in several domains of industry like heat exchangers, gas turbine blades, IC engine surfaces etc. The surfaces of these heat transfer applications are either naturally rough owing to manufacturing techniques or become rough over a period of time during operation. These rough surfaces usually contain...master thesis 2020

Accou, B.O.R. (author), Reniers, G.L.L.M.E. (author)Although mandatory in most high-risk industries, the safety management system (SMS) is often criticized as burdensome and complex. Through its requirement to formalize all main activities, the SMS is perceived as bureaucratic and a vehicle for pure compliance and Safety I (one). Furthermore, the SMS is often detached from an organization’s...journal article 2020

Ural, Osman (author)New York is currently going through a construction boom as developers try to take advantage of rising land values and rents caused by economic growth, resulting in a lack of affordable housing available to middle-income families. The current Mayor of New York, Bill de Blasio, has made it a priority to meet the demands and challenges of the...master thesis 2019

(author), Honecker, Dirk (author), Pipich, Vitaliy (author), Grigoriev, Sergey V. (author)This paper reports on the two-scale fractal structure of chromatin organization in the nucleus of the HeLa cell. Two neutron scattering methods, small-angle neutron scattering (SANS) and spin-echo SANS, are used to unambiguously identify the large-scale structure as being a logarithmic fractal with the correlation function (r) - ln(r/E). The...journal article 2019

Liu, H. (author)Digital elevation models (DEM) are widely used in various distributed hydrological models. The stream network can be extracted from it so that runoff routing can be calculated. With the advent of remote sensing and computing technologies, the computation based on DEM with high resolution becomes possible. However, there still exist regions with...conference paper 2018

Murugesan, Yaswanth (author)Various contact mechanics theories have been developed in recent years. The most popular are the statistical asperity theories of the type of Greenwood and Williamson and Persson’s theory, which treats self affine rough surfaces. The latter theory includes roughness at all length scales as well as long range elastic interactions. However, it is...master thesis 2017
