van der Burg, S. (author), Jurg, M.F.M. (author), Tadema, F.M. (author), Kamp, L.M. (author), van de Kaa, G. (author)This paper focuses on the design of the wings used in airborne wind energy systems. At the moment, two different designs are being developed: soft wings and rigid wings. This paper aimed to establish which of the two alternative design choices has the highest chance of dominance and which factors affect that. We treated this problem as a battle...journal article 2022

Rooij, R.M. (author), Mooij, S.C. (author)Teaching design skills to engineering students has long been one of the main building blocks of the bachelor curriculums at the TU Delft faculties of Industrial Design Engineering and Architecture & the Built Environment. We observe that our students achieve high-level (design) competencies during their study time at TU Delft. But we also...conference paper 2022

Fabiani, Filippo (author), Tajeddini, Mohammad Amin (author), Kebriaei, Hamed (author), Grammatico, S. (author)We propose a two-layer, semi-decentralized algorithm to compute a local solution to the Stackelberg equilibrium problem in aggregative games with coupling constraints. Specifically, we focus on a single-leader, multiple follower problem, and after equivalently recasting the Stackelberg game as a mathematical program with complementarity...journal article 2022

Kim, E. (author), Park, Ji Won (author), Noh, Jin Hyung (author), Bae, Young Ho (author), Maeng, Sung Kyu (author)Since 2021, national standards of South Korea for industrial wastewater discharge to surface water have changed from chemical oxygen demand to total organic carbon for the organic matter. Conventional organic matter parameters (e.g., biochemical oxygen demand, chemical oxygen demand and total organic carbon) are limited means of understanding...journal article 2022

Wu, Yuhao (author), de Vries, H.J. (author)A technical standards alliance (TSA) is a collection of firms organized for a common goal: developing, revising, and promoting technical standards. A firm may participate in standardization through one or more TSAs: its TSA network. However, little is known about the influencing factors and their boundary conditions for gaining firm-level...journal article 2022

(author), Zhang, Kouchi (author)Board level vibration testing is intended to assess prediction of the reliability of solder joint interconnects that are formed between electronic components and printed circuit boards (PCB). Frailties in the stress test experiment might lead to false board level reliability (BLR) evaluations. Therefore, it is essential to have a well...review 2022

Kok, M. (author)Risk-informed decision-making needs methods for assessing flood risk, and often the flooding probability and the consequences of floods (such as economic damage and fatalities) play an important role in the risk assessment. Also, measures to reduce the flood risk need to be formulated, in order to make a risk-informed decision, whether to...book chapter 2022

Wiarda, M.J. (author), van de Kaa, G. (author), Doorn, N. (author), Yaghmaei, E. (author)Standardisation is increasingly seen as a means to insert ethics in innovation processes. We examine the institutionalisation of responsible innovation in de jure standardisation as this is an important but unexplored research area. In de jure standardisation, stakeholders collaborate in committees to develop standards. We adopt the anticipation...journal article 2022

This article explores how technological uncertainty affects the coordination mechanism for standardization. The article is based on the Community Innovation Survey, a sizeable firm-level survey representative of the...journal article 2022

li Piani, T. (author), Weerheijm, J. (author), Sluys, Lambertus J. (author)Adobe is a traditional masonry made of sundried earthen bricks and mud mortar. Despite a millennial history of buildings of architectural value, adobe still connotes a so called ‘not engineered’ construction type. Namely, the material and structural properties of adobe are still not entirely addressed, resulting in an equally uncertain...journal article 2022
