Balagué Guardia, D. (author), Barbaro, Alethea (author), Carrillo, Jose Antonio (author), Volkin, Robert (author)We study distributional solutions to the radially symmetric aggregation equation for power-law potentials. We show that distributions containing spherical shells form part of a basin of attraction in the space of solutions in the sense of “shifting stability." For spherical shell initial data, we prove the exponential convergence of solutions to...journal article 2020

Wang, Zhengbing (author), Townend, Ian (author), Stive, M.J.F. (author)Aggregation is used to represent the real world in a model at an appropriate level of abstraction. We used the convection-diffusion equation to<br/>examine the implications of aggregation progressing from a three-dimensional (3D) spatial description to a model representing a system as a<br/>single box that exchanges sediment with the adjacent...journal article 2020

Pradena, M.A. (author), Houben, L.J.M. (author), César, Andrés (author)Aggregate interlock is the dominant load transfer mechanism in non-dowelled Jointed Plain Concrete Pavements, as the innovative short concrete slabs. Although the Load Transfer Efficiency of this pavement innovation is based on that mechanism, the structural design methods do not relate the Load Transfer Efficiency by aggregate interlock with...journal article 2020

Peltenburg, J.W. (author), Brobbel, M. (author), van Straten, J. (author), Al-Ars, Z. (author), Hofstee, H.P. (author)Streaming dataflow designs describe hardware by connecting components through streams that transport data structures. We introduce a stream-oriented specification and type system that provides a clear and intuitive way to map complex, dynamically-sized data structures onto hardware streams. This helps designers to lift the abstraction of...journal article 2020

Tyuryukanov, I. (author), Popov, M. (author), van der Meijden, M.A.M.M. (author), Terzija, Vladimir (author)Identifying generator coherency with respect to slow oscillatory modes has numerous power system use cases including dynamic model reduction, dynamic security analysis, or system integrity protection schemes (e.g., power system islanding). Despite their popularity in both research and industry, classic eigenvector-based slow coherency techniques...journal article 2020

(author)The aggregation behavior of asphaltene in aqueous solution is systematically investigated based on a classical molecular dynamics study. In this work, a novel approach is adopted in order to investigate the structural and dynamical properties of the asphaltene nanoaggregates using different water models. The end-to-end distance of the...journal article 2020

Najafian, S. (author), Herzog, Daniel (author), Qiu, S. (author), Inel, O. (author), Tintarev, N. (author)Most recommender systems propose items to individual users. However, in domains such as tourism, people often consume items in groups rather than individually. Different individual preferences in such a group can be difficult to resolve, and often compromises need to be made. Social choice strategies can be used to aggregate the preferences of...conference paper 2020

Evans, Michael (author), Tindemans, Simon H. (author), Angeli, David (author)We consider the problem of dispatching a fleet of heterogeneous energy storage units to provide grid support. Under the restriction that recharging is not possible during the time frame of interest, we develop an aggregate measure of fleet flexibility with an intuitive graphical interpretation. This analytical expression summarises the full set...journal article 2020

Ouyang, Xiaowei (author), Wang, Liquan (author), Xu, Shida (author), Ma, Yuwei (author), Ye, G. (author)Carbonation treatment can effectively improve the performance of recycled concrete aggregate and fines due to the reactions of CO<sub>2</sub> with CH and C–S–H gel of cement paste. To better understand the mechanisms involved in the performance improvement, the surface properties of carbonated recycled cement paste powder (CRP) and its effect...journal article 2020

Gebremariam, A.T. (author), Di Maio, F. (author), Vahidi, A. (author), Rem, P.C. (author)Currently, natural resources are consumed at an alarming rate than their production (United Nations Environment Programme, 2014). This imposes unprecedented pressure on the environment. The problem seems to get worse with the present increase in population and demand for infrastructures. To alleviate these and other related problems, a circular...journal article 2020

(author)The Radiative-Convective Equilibrium Model Intercomparison Project (RCEMIP) is an intercomparison of multiple types of numerical models configured in radiative-convective equilibrium (RCE). RCE is an idealization of the tropical atmosphere that has long been used to study basic questions in climate science. Here, we employ RCE to investigate the...journal article 2020

Yalçinkaya, Ç. (author), Felekoglu, Burak (author), Yazici, Halit (author)Rheology and shrinkage are the key features that should be controlled to perform a successful casting process and obtain a durable ultra-high performance concrete (UHPC). It is anticipated that cast-in-situ applications of UHPC will increase in the near future, so the studies on early-age properties of UHPC have come into prominence. However,...journal article 2020

Poplavskaya, K. (author), De Vries, Laurens (author)At the forefront of energy transition, aggregators unlock value in front of and behind the energy meter. The business models of aggregators are changing rapidly, influenced by changes in technology, the market design, and regulatory framework. This chapter provides an overview of the leading aggregators in Europe and their underlying business...book chapter 2020

Najafian, S. (author), Inel, O. (author), Tintarev, N. (author)Explanations can be used to supply transparency in recommender systems (RSs). However, when presenting a shared explanation to a group, we need to balance users' need for privacy with their need for transparency. This is particularly challenging when group members have highly diverging tastes and individuals are confronted with items they do not...conference paper 2020

Najafian, S. (author)In some scenarios, like music or tourism, people often consume items in groups. However, reaching a consensus is difficult as different members of the group may have highly diverging tastes. To keep the rest of the group satisfied, an individual might need to be confronted occasionally with items they do not like. In this context, presenting an...conference paper 2020

van Rijswijk, Tom (author)Construction and demolition waste form a significant problem in terms of environmental pollution and material depletion. Concrete, as part of construction and demolition waste, is already responsible for 9% of the total anthropogenic carbon dioxide emissions. Consequently, it is important to alleviate the environmental stress of concrete by...bachelor thesis 2019
