Duives, D.C. (author), Ton, Danique (author)Crowding is often analyzed using crowd dynamics variables. Yet, it is questionable whether quantitative variables fully describe the perception of crowdedness. This paper presents four case studies into the Pedestrian Level-of-Service (PLoS), featuring a 1) mass event, 2) shopping environment, 3) festival, and 4) touristic hotspot. The...journal article 2024

Okur, Ö. (author), Fiori, Francesco (author), Fouladvand, Javanshir (author)Renewable heating systems (RHS), such as solar thermal, geothermal, heat pumps, wood pellets, biomass, are essential to reduce dependence on fossil fuel-based heating systems and resulting CO<sub>2</sub> emissions. Despite their benefits in terms of CO<sub>2</sub> emissions, the widespread adoption of RHS has yet to be achieved. This paper...journal article 2024

Fouladvand, Javanshir (author), Fiori, Francesco (author), Okur, Ö. (author)The European energy system is undergoing a drastic change, focusing on reducing natural gas consumption and import. European households, which are responsible for 25 % of final energy consumption, mainly based on natural gas, could play a significant role in such a transition. Therefore, the study aims to understand the perception towards...journal article 2024

Blokland, M. (author), van der Mei, R. D. (author), Pruyn, J.F.J. (author), Berkhout, J. (author)Piping systems are common in many architectures and designing such systems is often a complex task. Design automation of piping systems is therefore a universal research subject. Nonetheless, these piping systems are often still designed by hand as a result of their complexity. Consequently, costs associated with piping design are high,...journal article 2023

Aydoğan, Reyhan (author), Jonker, C.M. (author)This paper introduces a dependency analysis and a categorization of conceptualized and existing economic decision support mechanisms for negotiation. The focus of our survey is on economic decision support mechanisms, although some behavioural support mechanisms were included, to recognize the important work in that area. We categorize...conference paper 2023

Segundo Sevilla, Felix Rafael (author), Liu, Yanli (author), Barocio, Emilio (author), Korba, Petr (author), Andrade, Manuel (author), Chaudhuri, Balarko (author), Cremer, Jochen (author), Rueda, José L. (author), Tindemans, Simon H. (author)Nowadays, transmission system operators require higher degree of observability in real-time to gain situational awareness and improve the decision-making process to guarantee a safe and reliable operation. Digitalization of energy systems allows utilities to monitor the system dynamic performance in real-time at fast time scales. The use of...journal article 2022

Ho, Man Ying (Annie) (author), Lai, Joseph H.K. (author), Hou, H. (author), Zhang, D. (author)Key performance indicators (KPIs) are quintessentially useful for performance evaluation, but a set of pragmatic KPIs for holistic evaluation of retrofits for commercial buildings is hitherto unavailable. This study was conducted to address this issue. Built upon the findings of a systematic literature review and a focus group meeting in the...journal article 2021

Hoicka, Christina E. (author), Das, Runa R. (author), Zhao, Yuxu (author), McMaster, Maria Louise (author), Lieu, J. (author), Wyse, Susan (author)The rapid diffusion of demand-side low-carbon innovations has been identified as a key strategy for maintaining average global temperature rise at or below 1.5 °C. Diffusion research tends to focus on a single sector, or single technology case study, and on a small scope of factors that influence innovation diffusion. This paper describes a...journal article 2021

Chappin, E.J.L. (author), Bouwmans, I. (author), Deijkers, Emma (author)This paper introduces EMLab-Consumer, an agent-based model developed in the H2020 project Cheetah, on energy efficiency of households. The model builds on the theory of planned behavior, a large European survey and a variety of choice models generated from the same survey. It studies adoption of a number of energy efficient appliances and...conference paper 2021

Kleiman, F. (author), Janssen, M.F.W.H.A. (author), Meijer, Sebastiaan (author)The adoption of open data policy-making by governments is limited due to different types of constraints. Civil servants are reluctant to open their data to the public for many reasons. The lack of knowledge of benefits that can be produced by the release of data and the overestimation of risks and operational complexity seems to decrease...conference paper 2021

van Dijk, Tom (author)With a growing number of drones, the risk of collision with other air traffic or fixed obstacles increases. New safety measures are required to keep the operation of Unmanned Aerial Vehicles (UAVs) safe. One of these measures is the use of a Collision Avoidance System (CAS), a system that helps the drone autonomously detect and avoid obstacles....report 2020

Eijkelenboom, A.M. (author), Kim, D.H. (author), Bluyssen, P.M. (author)It is well known that the demand on hospital staff is increasing and that their comfort and health may be affected negatively by dose and building-related aspects. Comfort and health may differ between hospital departments. However, outpatient areas are understudied. To better understand comfort and health of staff in outpatient areas a survey...journal article 2020

Rudenko, Andrey (author), Palmieri, Luigi (author), Herman, Michael (author), Kitani, Kris M. (author), Gavrila, D. (author), Arras, Kai O. (author)With growing numbers of intelligent autonomous systems in human environments, the ability of such systems to perceive, understand, and anticipate human behavior becomes increasingly important. Specifically, predicting future positions of dynamic agents and planning considering such predictions are key tasks for self-driving vehicles, service...review 2020

De Schutter, B.H.K. (author), van den Boom, A.J.J. (author), Xu, J. (author), Safaei Farahani, S. (author)The objective of this paper is to provide a concise introduction to the max-plus algebra and to max-plus linear discrete-event systems. We present the basic concepts of the max-plus algebra and explain how it can be used to model a specific class of discrete-event systems with synchronization but no concurrency. Such systems are called max...journal article 2020

(author), Neerincx, M.A. (author), Truong, Khiet P. (author)An important aspect of human emotion perception is the use of contextual information to understand others' feelings even in situations where their behavior is not very expressive or has an emotionally ambiguous meaning. For technology to successfully detect affect, it must mimic this human ability when analyzing audiovisual input. Databases...conference paper 2019

Fang, J. (author), Mulder, Yvo T.B. (author), Hidders, Jan (author), Lee, Jinho (author), Hofstee, H.P. (author)While FPGAs have seen prior use in database systems, in recent years interest in using FPGA to accelerate databases has declined in both industry and academia for the following three reasons. First, specifically for in-memory databases, FPGAs integrated with conventional I/O provide insufficient bandwidth, limiting performance. Second, GPUs,...journal article 2019

Wolbertus, R. (author), van den Hoed, Robert (author)Fast charging is seen as a means to facilitate long-distance driving for electric vehicles (EVs). As a result, roll-out planning generally takes a corridor approach. However, with higher penetration of electric vehicles in urban areas, cities contemplate whether inner-city fast chargers can be an alternative for the growing amount of slow public...journal article 2019
