Sun, Yubo (author), Ghorbani, Saeid (author), Ye, G. (author), De Schutter, Geert (author)Alkali-activated material (AAM) is developed as a green alternative binder to replace Portland cement (PC) in the construction field. However, the large-scale application with AAM concrete is limited so far, with the insufficient knowledge of rheological behavior being a major obstruct. Thixotropy of concrete is of great interest, which can...book chapter 2023

Su, Z. (author), Jamshidi, A. (author), Nunez, Alfredo (author), Baldi, S. (author), De Schutter, B.H.K. (author)We develop a Model Predictive Control (MPC) approach for condition-based maintenance planning under uncertainty for railway infrastructure systems composed of multiple components. Piecewise-affine models with uncertain parameters are used to capture both the nonlinearity and uncertainties in the deterioration process. To keep a balance...book chapter 2019

(author)With an increasing use of distributed energy resources and intelligence in the electricity infrastructure, the possibilities for minimizing costs of household energy consumption increase. Technology is moving toward a situation in which households manage their own energy generation and consumption, possibly in cooperation with each other. As a...conference paper 2007

Arnold, M. (author), Negenborn, R.R. (author), Andersson, G. (author), De Schutter, B. (author)The optimal operation of an integrated electricity and natural gas infrastructure is investigated. The couplings between the electricity system and the gas system are modeled by so-called energy hubs, which represent the interface between the loads on the one hand and the transmission infrastructures on the other. To increase reliability and...conference paper 2009

Negenborn, R.R. (author), De Schutter, B. (author), Hellendoorn, J. (author)We discuss an extension of a scheme recently proposed for multi-agent control of large-scale networks, like power networks, road traffic networks, water networks, etc. The original scheme uses serial sequences of agent interactions that under some assumptions make agents locally choose actions that are globally optimal. However, some weaknesses...conference paper 2007

Hug-Glanzmann, G. (author), Negenborn, R.R. (author), Andersson, G. (author), De Schutter, B. (author), Hellendoorn, H. (author)As power systems generally are large interconnected systems controlled by several parties, centralized optimal power flow (OPF) control taking the entire grid into account is often not feasible. To use optimal control in power systems nevertheless, the overall system is decomposed into areas with associated subproblems, which are solved in an...conference paper 2007

Van der Vurst, F. (author), Grunewald, S. (author), De Schutter, G. (author)Over time, several mix design metliods liave been developed to obtain a selfcompacting concrete (SCC) with suitable fresh and hardened concrete properties. The very fluid concrete with no need for external compaction is achieved by using a higher powder content and the use of chemical admixtures. Segregation and bleeding are prevented by either...conference paper 2015

Negenborn, R.R. (author), Sahin, A. (author), Lukszo, Z. (author), De Schutter, B. (author), Morari, M. (author)Irrigation canals transport water from water sources (such as large rivers and lakes) to water users (such as farmers). Irrigation canals are typically very large in nature, covering vast geographical areas, and involving a significant number of control actuators, such as pumps, gates, and locks. The control of such canals is aimed at...conference paper 2009

Patel, R.A. (author), Perko, J. (author), Jacques, D. (author), De Schutter, G. (author), Van Breugel, K. (author), Ye, G. (author)Calcium leaching is one of the important degradation mechanisms causing dissolution of the crystalline phases such as, AFm, portlandite increasing capillary porosity. Further it leads to decalcification of an amorphous C-S-H phase causing increase in the gel porosity and in turn degrading the long term performance of concrete structures. In this...conference paper 2014

Negenborn, R.R. (author), De Schutter, B. (author), Hellendoorn, H. (author)We consider multi-agent, or distributed, control of transportation networks, like traffic, water, and power networks. These networks typically have a large geographical span, modular structure, and a large number of components that require control. We discuss the necessity of a multi-agent control setting in which multiple agents control parts...conference paper 2006

(author)Emergency voltage control problems in electric power networks have stimulated the interest for the implementation of online optimal control techniques. Briefly stated, voltage instability stems from the attempt of load dynamics to restore power consumption beyond the capability of the transmission and generation system. Typically, this situation...conference paper 2007

Van der Vurst, F. (author), Grunewald, S. (author), Feys, D. (author), De Schutter, G. (author)In order to avoid durability problems caused by an inadequate consolidation of concrete, self-compacting concrete (SCC) has been developed. The mix design of SCC aims at balancing a minimum flowability allowing air bubbles to escape and a maximum flowability in order to avoid segregation. Because of the higher demands on mix design and...conference paper 2015
