(author), Kayuni, Martha Nchimunya (author), Langejans, G.H.J. (author)This study explores traditional adhesives using an ethnobiological approach within a multisocioecological context in Zambia. Through semi-structured interviews, videotaped demonstrations, and herbarium collections, we investigated the traditional adhesives people know and use, the flexibility of production processes, resource usage, and...journal article 2024

(author), Wimmler, Marie Christin (author), Grimm, Volker (author)Despite the increasing use of standards for documenting and testing agent-based models (ABMs) and sharing of open access code, most ABMs are still developed from scratch. This is not only inefficient, but also leads to ad hoc and often inconsistent implementations of the same theories in computational code and delays progress in the...journal article 2024

Tao, T. (author), Roy, Spandan (author), De Schutter, B.H.K. (author), Baldi, S. (author)In this work we propose a new practical synchronization protocol for multiple Euler Lagrange (EL) systems without structural linear-in-the-parameters (LIP) knowledge of the uncertainty and where the agents can be interconnected before control design by unknown state-dependent interconnection terms. This setting is meant to overcome two...journal article 2024

Yue, Dongdong (author), Baldi, S. (author), Cao, Jinde (author), Li, Qi (author), De Schutter, B.H.K. (author)This paper addresses distributed adaptive optimal resource allocation problems over weight-balanced digraphs. By leveraging state-of-the-art adaptive coupling designs for multiagent systems, two adaptive algorithms are proposed, namely a directed-spanning-tree-based algorithm and a node-based algorithm. The benefits of these algorithms are...journal article 2023

This work describes the Metacontrol method for self-adaptation in robotics. Particularly, it details how the MROS (Metacontrol for ROS Systems) framework implements and pack- ages Metacontrol, and it demonstrate how MROS can be applied in a navigation...conference paper 2023

Banerjee, I. (author)In a dynamic or disruptive situation, such as disasters, a fully mobile and decentralized infrastructure-less network seems to be a viable option for communication. Citizens are confronted with challenges such as complicated deployment of these networks, resource-constrained mobile phones and mobility. This requires communication networks to...doctoral thesis 2022

Luteijn-Nava Guerrero, G.D.C. (author)In the Netherlands, a complex heat transition is taking place. Currently, the country's built environment largely relies on natural gas for heating. By 2050, the housing sector should, in principle, be free of this fuel. Changes in laws, policies, regulations, and technical solutions to achieve this goal will be challenging. Their implementation...doctoral thesis 2022

Jarne Ornia, D. (author), Zufiria, Pedro J. (author), Mazo, M. (author)Collaborative multiagent robotic systems, where agents coordinate by modifying a shared environment often result in undesired dynamical couplings that complicate the analysis and experiments when solving a specific problem or task. Simultaneously, biologically inspired robotics rely on simplifying agents and increasing their number to obtain...journal article 2022

Nikolic, I. (author), Kolk, W.P.H. (author), Paape, Leen (author), de Korte, Ron (author)This paper presents a theoretical framework for a new concept of organizational control, that stimulates organizational change and adaptation. It introduces Participatory Control Systems (PCS) as a distinct type of control based on the complex adaptive system literature. These control systems are fundamentally different from the traditional...journal article 2022

IJtsma, Martijn (author), Borst, C. (author), van Paassen, M.M. (author), Mulder, Max (author)Air traffic controller workload is a limiting factor in the current air traffic management system. Adaptive support systems have the potential to balance controller workload and gain acceptance as they provide support during times of need. Challenges in the design of adaptive support systems are to decide when and how to trigger support. The...journal article 2022

Wang, X. (author), Roy, Spandan (author), Fari, S. (author), Baldi, S. (author)The high maneuverability of fixed-wing unmanned aerial vehicles (UAVs) exposes these systems to several dynamical and parametric uncertainties, severely affecting the fidelity of modeling and causing limited guidance autonomy. This article shows enhanced autonomy via adaptation mechanisms embedded in the guidance law: a vector-field method is...journal article 2022

Tao, T. (author), Roy, S. (author), Baldi, S. (author)This work introduces a new single-stage adaptive controller for Euler-Lagrange systems with nonholonomic constraints. The proposed mechanism provides a simpler design philosophy compared to double-stage mechanisms (that address kinematics and dynamics in two steps), while achieving analogous stability properties, i.e. stability of both original...conference paper 2022

Simoes Silva, Douglas (author), Graczyk, Rafal (author), Decouchant, Jérémie (author), Völp, Marcus (author), Esteves-Veríssimo, Paulo (author)Critical infrastructures have to withstand advanced and persistent threats, which can be addressed using Byzantine fault tolerant state-machine replication (BFT-SMR). In practice, unattended cyberdefense systems rely on threat level detectors that synchronously inform them of changing threat levels. However, to have a BFT-SMR protocol operate...conference paper 2021

(author)To reduce greenhouse gas emissions to 80% below 1990 levels by 2050, an energy transition is taking place in the European Union. Achieving these targets requires changes in the heating and cooling sector (H&C). Designing and implementing this energy transition is not trivial, as technology, actors, and institutions interact in complex ways....journal article 2019

Roungas, V. (author), Bekius, F.A. (author), Meijer, S.A. (author)Background. The abstraction of complex systems, which is required by default when modelling gaming simulations, is a convoluted and time-consuming process. For gaming simulations to be efficient and effective, the problem of the real system they imitate needs to be narrowed down and simplified as much as possible. Additionally, even after...journal article 2019
