Mayer, Jakob (author), Süsser, Diana (author), Pickering, Bryn (author), Bachner, Gabriel (author), Sanvito, F.D. (author)Net-zero energy system configurations can be met in numerous ways, implying diverse economic effects. However, what is usually ignored in techno-economic and economy-wide analysis are the distinct social-political drivers and barriers, which might constrain certain elements of future energy systems. We thus apply a model ensemble that defines...journal article 2024

(author), De Ras, Kevin (author), Vlugt, T.J.H. (author)The use of reactive working fluids in thermodynamic cycles is currently being considered as an alternative to inert working fluids, because of the preliminarily attested higher energy-efficiency potential. The current needs to simulate their use in thermodynamic cycles, which may operate in liquid, vapour or vapour-liquid state, are an...journal article 2024

Fan, Q. (author), van Essen, J.T. (author), Correia, Gonçalo (author)Ride-hailing companies will face the emergence and gradual expansion of AVs-only zones in urban areas where only automated vehicles (AVs) are allowed to circulate. When owning a mixed fleet (automated and conventional taxis), a ride-hailing company has to determine the optimal fleet size as a function of the gradually expanding coverage of...journal article 2024

Cruz Rojas, Juan (author)From a global perspective, the building industry is one of the significant factors of environmental impact on the planet. Related activities in this industry refer to 40% of total carbon emissions; 28% of this value accounts for building operations, while the remaining 12% represents the manufacturing of new construction materials. Studies have...master thesis 2023

Lingmont, Roald (author)In order to scale the planar flow casting (PFC) process to industrial levels a Python model is created. The model which is based on a combination of empirical and theoretical equations, is used to explore the limits of the process. The model is independently verified with a Comsol simulation, which is extended with solidification and heat...master thesis 2023

Krilašević, S. (author)Both societal and engineering systems are growing in complexity and interconnectivity, making it increasingly challenging, and sometimes impossible, to model their dynamics and behaviors. Moreover, individuals or entities within these systems, often referred to as agents, have their own objectives that may conflict with one another. Examples...doctoral thesis 2023

van Tol, Berend (author)In this thesis, we study stochastic duality under hydrodynamic scaling in the context of interacting particles on a grid. The approach is inspired and motivated by the relation between duality and local equilibria. We identify duality relations in terms of the expectation of the density field for which the hydrodynamic limit is recovered. This...master thesis 2023

IJzermans, Eva (author)In 2015, the UN coined 17 Sustainable Development Goals (SDGs), with each goal based on three pillars: society, environment, and economy. Rapid growth can result in a country not succeeding in developing all pillars simultaneously. This, in turn, can lead to a stagnation of development. Ethiopia is a clear example of such stagnation, as inject...master thesis 2023

Franci, B. (author), Grammatico, S. (author)Generative adversarial networks (GANs) are a class of generative models with two antagonistic neural networks: a generator and a discriminator. These two neural networks compete against each other through an adversarial process that can be modeled as a stochastic Nash equilibrium problem. Since the associated training process is challenging,...journal article 2023

Lavrinenko, A.K. (author), Chernyshov, I. (author), Pidko, E.A. (author)Deep eutectic solvents (DESs) represent an environmentally friendly alternative to conventional organic solvents. Their liquid range determines the areas of application, and therefore, the prediction of solid-liquid equilibrium (SLE) diagrams is essential for developing new DESs. Such predictions are not yet possible by using the current...journal article 2023

Madadi, B. (author), Correia, Gonçalo (author)This study proposes a hybrid deep-learning-metaheuristic framework with a bi-level architecture for road network design problems (NDPs). We train a graph neural network (GNN) to approximate the solution of the user equilibrium (UE) traffic assignment problem and use inferences made by the trained model to calculate fitness function...journal article 2023

Li, G. (author), Lewis, R.W. (author), Eelkema, R. (author)The field of supramolecular chemistry is rapidly progressing, transitioning from the creation of thermodynamically stable systems found in local or global minima on the free energy landscape to the development of out-of-equilibrium systems that rely on chemical reactions to establish and maintain their structures. Over the past decade,...review 2023

Benenati, E. (author), Ananduta, W. (author), Grammatico, S. (author)A fundamental open problem in monotone game theory is the computation of a specific generalized Nash equilibrium (GNE) among all the available ones, e.g. the optimal equilibrium with respect to a system-level objective. The existing GNE seeking algorithms have in fact convergence guarantees toward an arbitrary, possibly inefficient,...journal article 2023

Robust design of CAV-Dedicated lanes considering CAV demand uncertainty and lane reallocation policySeilabi, Sania E. (author), Pourgholamali, Mohammadhosein (author), Correia, Gonçalo (author), Labi, Samuel (author)Reduced headways of connected and automated vehicles (CAV) provide opportunities to address traffic congestion and environmental adversities. This benefit can be utilized by deploying CAV-dedicated lanes (CAVDL). This paper presents a bi-level optimization model that captures CAV market size uncertainty. The upper level determines the links ...journal article 2023

Liu, B. (author), Ji, Yuxiong (author), Cats, O. (author)Public transport (PT) agencies are increasingly keen on integrating ride-hailing (RH) services with PT to improve overall mobility. Understanding the traffic flow distribution in the integrated system is vital for the policy decision-making and services design of such a system. We propose a stochastic user equilibrium (SUE) model for...journal article 2023

Li, Jingqi (author), Chiu, Chih Yuan (author), Peters, L. (author), Sojoudi, Somayeh (author), Tomlin, Claire (author), Fridovich-Keil, David (author)In multi-agent dynamic games, the Nash equilibrium state trajectory of each agent is determined by its cost function and the information pattern of the game. However, the cost and trajectory of each agent may be unavailable to the other agents. Prior work on using partial observations to infer the costs in dynamic games assumes an open-loop...journal article 2023

Brederode, L.J.N. (author), Gerards, Lotte (author), Wismans, Luc (author), Pel, A.J. (author), Hoogendoorn, S.P. (author)To improve the accuracy of large-scale strategic transport models in congested conditions, this paper presents a straightforward extension of a static capacity-constrained traffic assignment model into a semi-dynamic version. The semi-dynamic model is more accurate than its static counterpart as it relaxes the empty network assumption, but,...journal article 2023
