Ligot, Antoine (author), Kuckling, Jonas (author), Bozhinoski, D. (author), Birattari, Mauro (author)We investigate the possibilities, challenges, and limitations that arise from the use of behavior trees in the context of the automatic modular design of collective behaviors in swarm robotics. To do so, we introduce Maple, an automatic design method that combines predefined modules—low-level behaviors and conditions— into a behavior tree that...journal article 2020

Pan, W. (author), Sun, Y. (author), Turrin, M. (author), Louter, P.C. (author), Sariyildiz, I.S. (author)During the early design process, simulations allow numeric assessment and 3D models allow visual inspection for qualitative criteria. However, exploring different design alternatives based on both is challenging. To support the design exploration of quantitative performance and geometry typology of various design alternatives during the early...journal article 2020

Collet, F. (author), Gorny, Matthias (author), Kraaij, R.C. (author)The dynamical Curie-Weiss model of self-organized criticality (SOC) was introduced in (Ann. Inst. Henri Poincaré Probab. Stat. 53 (2017) 658-678) and it is derived from the classical generalized Curie-Weiss by imposing a microscopic Markovian evolution having the distribution of the Curie-Weiss model of SOC (Ann. Probab. 44 (2016) 444-478) as...journal article 2020

Yang, D. (author), Di Stefano, Danilo (author), Turrin, M. (author), Sariyildiz, I.S. (author), Sun, Yimin (author)Simulation-Based Multi-Objective Optimization (SBMOO) methods are being increasingly used in conceptual architectural design. They mostly focus on the solving, rather than the re-formulation, of a Multi-Objective Optimization (MOO) problem. However, Optimization Problem Re-Formulation (Re-OPF) is necessary for treating ill-defined conceptual...journal article 2020

(author), Terryn, H.A. (author), Misiolek, Wojciech Z. (author)Self-organized anodization of copper in 0.1 M Na2CO3 electrolyte was studied in order to obtain nanostructured oxide surface on the metal substrate. Linear sweep voltammetry (LSV) revealed that the most suitable voltage range for anodic film formation is from 3 to 31 V. In this range (except between 3 and 7 V), the oxide is formed as nanorods,...journal article 2020

Banerjee, I. (author), Warnier, Martijn (author), Brazier, F.M. (author)When physical communication network infrastructures fail, infrastructure-less communication networks such as mobile ad-hoc networks (MANET), can provide an alternative. This, however, requires MANETs to be adaptable to dynamic contexts characterized by the changing density and mobility of devices and availability of energy sources. To address...journal article 2020

Yuan, Y. (author), Goni Ros, B. (author), Bui, Ha H. (author), Daamen, W. (author), Vu, Hai L. (author), Hoogendoorn, S.P. (author)Macroscopic pedestrian models are theoretically simpler than microscopic models, and they can potentially be solved faster while producing reasonable predictions of crowd dynamics. Therefore, they can be very useful for applications such as large-scale simulation, real-time state estimation and crowd management. However, the numerical methods...journal article 2020

Dang, Y. (author), Grundel, D.A.J. (author), Youk, H.O. (author)Cells form spatial patterns by coordinating their gene expressions. How a group of mesoscopic numbers (hundreds to thousands) of cells, without pre-existing morphogen gradients and spatial organization, self-organizes spatial patterns remains poorly understood. Of particular importance are dynamic spatial patterns such as spiral waves that...journal article 2020

Vergara d'Alençon, L.M. (author), Robertson, Cristián (author)We are facing a paradigm shift in the production of housing, and it is precisely in this transition where contexts as different as The Netherlands and Chile find a common denominator: the problem of affordability and general discontent in the face of a supply that is increasingly remote from the economic capacity and needs of people. Access...book chapter 2019

Coppola, Mario (author), Guo, J. (author), Gill, E.K.A. (author), de Croon, G.C.H.E. (author)In this paper we present a procedure to automatically design and verify the local behavior of robots with highly limited cognition. All robots are: anonymous, homogeneous, non-communicating, memoryless, reactive, do not know their global position, do not have global state information, and operate by a local clock. They only know: (1) the...journal article 2019

Czischke, D.K. (author)Against the backdrop of the current housing crisis, Europe has seen the (re)emergence of collectively self-organised housing projects. Collaborative housing stands as an umbrella term for the wide range of these housing forms, where groups of residents collectively design, develop and inhabit housing. This chapter provides a brief...book chapter 2019

Czischke, D.K. (author), Schlack, Elke (author)By way of introduction, this chapter explains the main differences and convergences in housing provision paradigms in European and Chilean cities. From housing as part of Welfare State models, both societies have seen the replacement of the right to housing by the financialization of housing. The chapter highlights a red thread in this book,...book chapter 2019

Vergara d'Alençon, L.M. (author)The development of self-organised neighbourhoods positions the residents at the centre of the process. They organise themselves to plan, densify and subsequently manage their dwellings collectively. This chapter focuses on defining the type of management that accompanies the housing densification in condominium tenure, and the challenges related...book chapter 2019

Causevic, S. (author), Warnier, Martijn (author), Brazier, F.M. (author)Ensuring access to reliable and sustainable power supply is becoming more and more challenging due to a combination of factors such as more frequent power grid outages caused by extreme weather events, the large-scale introduction of renewable energy resources that increases the complexity of the power system, but also aging infrastructure,...journal article 2019

Causevic, S. (author), Saxena, K. (author), Warnier, Martijn (author), Abhyankar, AR (author), Brazier, F.M. (author)Resilience of power systems is highly impacted by factors such as increasing severity and frequency of weather events, but also smart grid advances that introduce major operational changes in power systems. Rapidly adapting to these changing circumstances and harnessing the potential of technolo- gical advances is the key to ensuring that power...journal article 2019

Pan, W. (author), Sun, Yimin (author), Turrin, M. (author), Louter, P.C. (author), Sariyildiz, I.S. (author)The multi-functional space of sports arena is highly related to the long-span structure. To support the integration of these two aspects, design optimization combining parametric modeling, performance simulations, and searching algorithm can be used. However, optimization is powerful in dealing with quantitative performance, but for some soft...conference paper 2018
