Pedrotti, Matteo (author), Dieudonné, A.A.M. (author), Dijkstra, J. (author), Musso, Guido (author), Hattab, Mahdia (author), Viggiani, Gioacchino (author)The importance of physico-chemical processes at the particle scale for the engineering scale behaviour of fine-grained geomaterials is undisputed. Yet, despite great advances in the discipline, experimental evidence that fully resolves the clay micromechanics i.e. linking the evolving microstructure and interparticle actions under loading, is...conference paper 2023

Beselly, S.M. (author), Grueters, U. (author), van Der Wegen, M. (author), Reyns, J.A.H. (author), Dijkstra, J. (author), Roelvink, D. (author)As climate-change-driven extremes potentially make coastal areas more vulnerable, mangroves can help sustainably protect the coasts. There is a substantial understanding of both mangrove dynamics and hydro-morphodynamic processes. However, the knowledge of complex eco-geomorphic interactions with physical-environmental stressors remains...journal article 2023

Dijkstra, Aranka M. (author), Tiekstra, Siebrith M. (author), Boonstra, Marije (author), Joore, Peter (author)The use of Living Labs is a promising approach to develop and test sustainable system innovations. A Living Lab approach that is yet to be discussed in literature, is that of a Festival Living Lab (FLL). Festivals can be considered as temporary mini societies with systemic sustainability challenges regarding water, energy, housing, logistics,...conference paper 2023

(author), van Soest, Gijs (author), Regar, Evelyn (author)Safety and efficacy of coronary drug-eluting stents (DES) are often preclinically tested using healthy or minimally diseased swine. These generally show significant fibrotic neointima at follow-up, while in patients, incomplete healing is often observed. The aim of this study was to investigate neointima responses to DES in swine with...journal article 2023

Open Gimbal: A 3 Degrees of Freedom Open Source Sensing and Testing Platform for Nano and Micro UAVsSharma, Suryansh (author), Dijkstra, Tristan (author), Venkatesha Prasad, Ranga Rao (author)Testing the aerodynamics of micro-UAVs (mUAVs) and nano-UAVs (nUAVs) without actually flying is highly challenging. To address this issue, we introduce Open Gimbal, a specially designed 3 degrees of freedom (DoF) platform that caters to the unique requirements of mUAVs and nUAVs. This platform allows for unrestricted and free rotational...journal article 2023

Pintea, S. (author), Lin, Y. (author), Dijkstra, Jouke (author), van Gemert, J.C. (author)A number of computer vision deep regression approaches report improved results when adding a classification loss to the regression loss. Here, we explore why this is useful in practice and when it is beneficial. To do so, we start from precisely controlled dataset variations and data samplings and find that the effect of adding a classification...conference paper 2023

de Boer, Frans (author), van Gemert, J.C. (author), Dijkstra, Jouke (author), Pintea, S. (author)Activity progress prediction aims to estimate what percentage of an activity has been completed. Currently this is done with machine learning approaches, trained and evaluated on complicated and realistic video datasets. The videos in these datasets vary drastically in length and appearance. And some of the activities have unanticipated...conference paper 2023

(author), van Embden, Daphne (author), Jaarsma, Ruurd L. (author), Schwab, Joseph H. (author)Purpose: Effects of clockwise torque rotation onto proximal femoral fracture fixation have been subject of ongoing debate: fixated right-sided trochanteric fractures seem more rotationally stable than left-sided fractures in the biomechanical setting, but this theoretical advantage has not been demonstrated in the clinical setting to date.

Horemans, D.M.L. (author), Dijkstra, Y.M. (author), Tackx, Michèle (author), Meire, Patrick (author), Cox, Tom J.S. (author)Estuaries often show regions in which Chlorophyll-a (Chl-a) accumulates. The location and magnitude corresponding to such accumulation result from a complex interplay between processes such as river flushing, salinity, nutrients, grazing on phytoplankton, and the light climate in the water column. An example is the multi-annual evolution of...journal article 2023

Dijkstra, Kevin (author)Existence of commuting THB-spline projectors is of importance in the field of numerical mathematics. These projectors are required to show that numerical solutions to the abstract Hodge Laplace problem are stable and consistent. We have introduced a local THB-spline projector based on Bezier projection, that commutes in the one-dimensional case....master thesis 2022

Dijkstra, Twan (author)Estimating wave runup is of crucial importance during a coastal risk assessment. Currently, runup levels are usually calculated using empirical formula derived from experiments conducted at beaches all over the world, and during different beach states. During this research, conditions are analyzed where runup reaches the dune toe and above. The...master thesis 2022

The world is always changing, therefore the Netherlands, together with many countries, has to adapt constantly to the climate. This constant change means that in particular the coastline of the Netherlands requires extra attention because of the uncertainty of sea level rise. The...student report 2022
