Waardenburg, M. (author), Groenleer, M. (author), de Jong, J. (author), Keijser, B.M.J. (author)The literature suggests that collaborative governance efforts typically face three types of challenges: substantive problem-solving challenges, collaborative process challenges and multi-relational accountability challenges. In this article, we investigate how these challenges manifest themselves in practice and explore potential ways in which...article 2020

Leonetti, D. (author), Maljaars, J. (author), Pasquarelli, G. (author), Brando, G. (author)Hot-riveted connections have been widely used in the past for metallic bridges, of which a large part is still in service, making relevant the assessment of their fatigue life. Previous studies have shown that the fatigue behavior of hot-riveted connections depends on many factors; among these, the residual tensile force in the rivets that...article 2020

de Martin, L. (author), van Rossum, W. (author), Ribeiro, D. (author), Anitori, L. (author)It is well known that noise-like waveforms have the inherent property of suppressing ambiguities due to their nonrepetitive nature, as opposed to the more classical linear frequency modulated (LFM) pulsed waveforms. This aperiodicity also improves the robustness against jammers, making these waveforms harder to detect and classify by an enemy....article 2020

Willems, R. (author), Willems, F. (author), Simpson, T. (author), Albrecht, B. (author), Deen, N. (author), Somers, B. (author)CO2 regulations on heavy-duty transport are introduced in essentially all markets within the next decade, in most cases in several phases of increasing stringency. To cope with these mandates, developers of engines and related equipment are aiming to break new ground in the fields of combustion, fuel and hardware technologies. In this work, a...conference paper 2020

van Gulijk, C. (author), Holmes, V. (author)A key step in the design of digitally enabled safety systems is the development of an Enterprise Architecture model (EA). The design of EA models tends to be a complex job that is usually performed by IT specialists that are not trained in safety. Very often, these EA models contain safety rules that are not well understood by IT specialists but...conference paper 2020

Marques-Carneiro, J.E. (author), Polgari, P. (author), Koning, E. (author), Seyller, E. (author), Martin, B. (author), van der Burg, E. (author), Giersch, A. (author)Learning and imitating a complex motor action requires to visually follow complex movements, but conscious perception seems too slow for such tasks. Recent findings suggest that visual perception has a higher temporal resolution at an unconscious than at a conscious level. Here we investigate whether high-temporal resolution in visual perception...article 2020

(author), Mazanik, A.V. (author)The research on halide perovskites is in its peak activity at the moment due to the material's potential application in photovoltaics. It is well known that slow processes, from seconds to minutes, are very significant in perovskite films and devices as compared to conventional photovoltaic materials. The kinetics of photoluminescence (PL) is...article 2020
