de Meijer, F.J.J. (author), Sotirov, Renata (author)It is well known that by adding integrality constraints to the semidefinite programming (SDP) relaxation of the max-cut problem, the resulting integer semidefinite program is an exact formulation of the problem. In this paper we show similar results for a wide variety of discrete optimization problems for which SDP relaxations have been...journal article 2023

Papachristos, George (author), Papadonikolaki, E. (author), Morgan, Bethan (author)Sociotechnical transitions are mostly seen in the literature as processes where actors and technologies in small niches peripheral to an organizational field, accumulate momentum, scale up, aggregate, and eventually bring about large-scale regime change. Foundational examples include the British transition from sailing ships to steamships and...journal article 2024

Nijhuis, S. (author)Klimaatverandering en verstedelijking hebben grote gevolgen voor het beheer en de bescherming van cultuurhistorische landschappen. Vooral in historische buitenplaatslandschappen vormt klimaatadaptatie een belangrijke opgave. Daarbij gaat het om de overvloed of juist het tekort aan water en de bedreiging van de ooit nauwkeurig gekozen vegetatie...journal article 2021

van der Weele, Pieter (author), Rutte, R.J. (author)Velen kennen de naam Borssele door de kerncentrale, die vlak bij het dorp Borssele staat. Weinigen weten dat dit dorp in de Zak van Zuid-Beveland heel bijzonder is. Het werd in 1616 aangelegd volgens een zeer uitgesproken, symmetrische plattegrond: een rechthoekig plein te midden van een rechtlijnig stratenplan. Borssele is het enige dorp op de...journal article 2021

Wang, X. (author), Xiao, Y. (author), Rans, C.D. (author), Benedictus, R. (author), Groves, R.M. (author)Nanoparticle- (NP-) doped optical fibres show the potential to increase the signal-to-noise ratio and thus the sensitivity of optical fibre strain detection for structural health monitoring. In this paper, our previous experimental/simulation study is extended to a design study for strain monitoring. 100 nm spherical gold NPs were randomly...journal article 2024

Heidary, Amir (author), Ghaffarian Niasar, M. (author), Popov, M. (author)This paper introduces an innovative Magnetic Switch (MFS) designed to control and alter magnetic flux within energy system components, offering an alternative to conventional power electronic devices. The MFS comprises a low-current control coil, a control core, and a high-density magnetic flux-carrying main core combined with a main coil energy...journal article 2024

Rogers, Ciarán (author), de Marchi, Guido (author), Brandl, B.R. (author)In this Letter, we present the first systematic spectroscopic measurements of the near-infrared (NIR) hydrogen recombination lines Paschen alpha (Pa<sub>α</sub>λ = 1.875 µm) and Brackett beta (Br<sub>β</sub>λ = 2.626 µm), produced by pre-main-sequence (PMS) stars. Such stars include T Tauri and Herbig AeBe stars, located in the massive...journal article 2024

(author)This study proposes a new concept for an on-demand drug releasing device intended for integration into additively manufactured (i.e., 3D printed) orthopedic implants. The system comprises a surface with conduits connected to a subsurface reservoir used for storage and on-demand release of antimicrobial agents, covered with a cap that prevents...journal article 2024

Mo, J. (author), Niu, Yunfan (author), May, Alexander (author), Rommel, Mathias (author), Rossi, Chiara (author), Romijn, J. (author), Zhang, Kouchi (author), Vollebregt, S. (author)Integrated circuits based on wide bandgap semiconductors are considered an attractive option for meeting the demand for high-temperature electronics. Here, we report an analog-to-digital converter fabricated in a silicon carbide complementary metal-oxide-semiconductor technology now available through Europractice. The MOSFET component in this...journal article 2024

Hinz, J.P. (author), Jaeschke, Andrzej (author), Möller, M. (author), Vuik, Cornelis (author)This paper proposes a shape optimization algorithm based on the principles of Isogeometric Analysis (IGA) in which the parameterization of the geometry enters the problem formulation as an additional PDE-constraint. Inspired by the isoparametric principle of IGA, the parameterization and the governing state equation are treated using the same...journal article 2021

Arias Campo, M. (author), Carluccio, G. (author), Blanco, Darwin (author), Litschke, Oliver (author), Bruni, Simona (author), Llombart, Nuria (author)In this contribution, a broadband G-band leaky-wave (LW) fed lens antenna with an integrated dielectric grid polarizer is presented. The proposed wideband polarizer unit cell geometry enables its fabrication at frequencies higher than 100 GHz, presenting high transmission properties and low axial ratio (AR). A quasi-Analytic technique based...journal article 2021

Aydoğan, Reyhan (author), Kafali, Özgür (author), Arslan, Furkan (author), Jonker, C.M. (author), Singh, Munindar P. (author)Specifying a normative multiagent system (nMAS) is challenging, because different agents often have conflicting requirements. Whereas existing approaches can resolve clear-cut conflicts, tradeoffs might occur in practice among alternative nMAS specifications with no apparent resolution. To produce an nMAS specification that is acceptable to...journal article 2021

Jansen, H.M. (author)Our aim is to find sufficient conditions for weak convergence of stochastic integrals with respect to the state occupation measure of a Markov chain. First, we study properties of the state indicator function and the state occupation measure of a Markov chain. In particular, we establish weak convergence of the state occupation measure under...journal article 2021

Tabakovic, A. (author), van Vliet, Dave (author), Roetert-Steenbruggen, Kirsten (author), Leegwater, G.A. (author)Bitumen rejuvenators are used to improve or restore the physical and mechanical performance of aged bitumen. Traditional bitumen rejuvenators are a product of crude oil. As crude oil production declines and the environmental and financial costs of crude oil increase, there is an urgent need to identify more environmentally sustainable bitumen...journal article 2023
