Younis, A. (author), Benders, R. (author), Ramirez, J. (author), de Wolf, M. (author), Faaij, A. (author)The large-scale integration of variable renewable energy sources into the energy system presents techno–economic challenges. Long–term energy system optimization models fail to ade quately capture these challenges because of the low temporal resolution of these tools. This limitation has often been addressed either by direct improvements within...article 2022

Candela, T. (author), Goncalves Machado, C. (author), Leeuwenburgh, O. (author), ter Heege, J.H. (author)A newly developed modelling framework is presented which specifically focusses on the central Oklahoma case and the high-volume injection of wastewater, which led to a surge of induced seismicity. However, the modelling framework is versatile enough to be applied to any anthropogenic subsurface activities and should be seen as a good practice to...article 2022

Zhang, B. (author), Guo, C. (author), Lin, T. (author), Faaij, A.P.C. (author)Environmental factors, including greenhouse gas (GHG) emissions and soil organic carbon (SOC), should be considered when building a sustainable biofuel supply chain. This work developed a three-step optimization approach integrating a geographical information system-based mixed-integer linear programming model to economically optimize the...article 2022

Nadi, A. (author), Yorke-Smith, N. (author), van Lint, J.W.C. (author), Tavasszy, L.A. (author), Snelder, M. (author)Truck flow patterns can best be understood through the study of freight activities on a transportation network. These activities are often observable after the execution of tours resulting from a routing and scheduling optimization process where the traditional Capacitated Vehicle Routing Problem (CVRP) is used to minimize multiple objectives...conference paper 2022

van der Ploeg, C. (author), Alirezaei, M. (author), van de Wouw, N. (author), Esfahani, P.M. (author)In this article, we propose a tractable nonlinear fault estimation filter along with explicit performance bounds for a class of linear dynamical systems in the presence of both additive and nonlinear multiplicative faults. We consider the case, where both faults may occur simultaneously and through an identical dynamical relationship, a setting...article 2022

(author), Yorke-Smith, N. (author)Logistics planning is a complex optimization problem involving multiple decision makers. Automated scheduling systems offer support to human planners; however state-of-the-art approaches often employ a centralized control paradigm. While these approaches have shown great value, their application is hindered in dynamic settings with no central...conference paper 2022

Eledlebi, K. (author), Ruta, D. (author), Hildmann, H. (author), Saffre, F. (author), al Hammadi, Y. (author), Isakovic, A.F. (author)When deploying a wireless sensor network (WSN) identifying optimal locations for the nodes is challenging, especially so if the environment is either (i) unknown or (ii) obstacle-rich. We proposes BISON (Bio-Inspired Self-Organizing Network), a variant of the Voronoi algorithm to address this challenge. Among the features of the approach are the...article 2022

Sharma, S. (author), van Lint, H. (author), Tavasszy, L.A. (author), Snelder, M. (author)Optimizing route choices for truck drivers is a key element in achieving reliable road freight operations. For commercial reasons, it is often difficult to collect freight activity data through traditional surveys. Automated vehicle identification (AVI) data on fixed locations (e.g., Bluetooth or camera) are low-cost alternatives that may hold...article 2022

Rasheed, M.B. (author), R-Moreno, M.D. (author)To meet the carbon-free energy and water demand requirements by Europe, this work has proposed an interconnected and integrated-energy-water-hydrogen (IEWH) system. Typically these systems are generally uncoupled, however, they may be interconnected and can be operated to provide green energy and water with reduced carbon footprints. This work...conference paper 2022

Tacx, P. (author), Habraken, R. (author), Witvoet, G. (author), Kuiper, S. (author), Heertjes, M. (author), Oomen, T. (author)Adaptive optics systems are essential in ground-based astronomical observatories and in laser communication through free space. In particular, turbulence in the atmosphere causes wavefront aberrations that set a limit on the achievable image quality. Adaptive optics systems allow to actively compensate the atmospheric disturbances which leads to...conference paper 2022

Romero, N. (author), van der Linden, K. (author), Morales España, G.A. (author), de Weerdt, M.M. (author)The power system is undergoing a significant change as it adapts to the intermittency and uncertainty from renewable generation. Flexibility from loads such as electric vehicles (EVs) can serve as reserves to sustain the supply-demand balance in the grid. Some reserve markets have rules for participation that are computationally challenging for...article 2021

(author)Additive manufacturing provides the possibility to manufacture parts on demand and offers tremendous form freedom compared to traditional manufacturing methods. However, Fused Filament Fabrication (FFF) is not yet widely used for highly structurally loaded parts, as their strength is hard to control and to predict. In this work we aim to analyze...article 2021

Morales-Espana, G.A. (author), Nycander, E. (author), Sijm, J. (author)To lower pollution, it became imperative to integrate as much renewable energies as possible in power systems. This has been translated into forcing the maximum production of variable renewable energy (VRE) ---wind and solar--- into power systems operation. The increasing operational costs to maximize the VRE output became the price to pay in...conference paper 2021

Gómez, J.F. (author), Shoeibi Omrani, P.S. (author), Belfroid, S.P.C. (author)In gas wells, decreased/unstable production can occur due to difficult-to-predict dynamic effects resulted from late-life phenomena, such as liquid loading and flooding. To minimize the negative impact of these effects, maximize production and extend the wells’ lifetime, wells are often operated in an intermittent production regime. The goal of...conference paper 2021
