Jeon, Jaemin (author), Kim, Jaeyong (author), Lee, Jong Jun (author), Shin, D. (author), Kim, Yoon Young (author)This study presents a new modeling technique to estimate the stiffness matrix of a thin-walled beam-joint structure using deep learning. When thin-walled beams meet at joints, significant sectional deformations occur, such as warping and distortion. These deformations should be considered in the one-dimensional beam analysis, but it is...journal article 2022

Lee, Shenae (author), Khakzad, Nima (author), Schmitz, P.J.H. (author), Reniers, G.L.L.M.E. (author), Habrekke, Solfrid (author), Paltrinieri, Nicola (author)Hazardous events in process plants like the leakage of dangerous substances can result in severe damage, and such an event is often defined as the TOP event of a fault tree analysis (FTA) in a quantitative risk analysis. The TOP event probability can then be calculated if the basic events probabilities are provided. These probabilities are often...journal article 2022

Lee, Kelvin (author), Jiang, Yu (author), Ceder, Avishai (Avi) (author), Dauwels, J.H.G. (author), Su, Rong (author), Nielsen, Otto Anker (author)With the emergence of innovations associated with public transport (PT) services, such as Mobility-as-a-Service, demand responsive transit, and autonomous vehicles, the door-to-door PT journey is achievable via multiple transfers between and within different PT modes. As such, seamless transfers between different modes of public...journal article 2022

Lee, J. (author), Theuwissen, A.J.P.A.M. (author)A column-parallel 10-bit SAR ADC for high-speed image sensors has been implemented. A fast offset calibration technique using memory is proposed to compensate for the offset mismatch, accompanied by an ADC designed for a narrow space the size of a single column pitch. The memory accumulates the variation of the offset to track the offset...journal article 2022

Kim, Seon Hu (author), Lee, Cheol Ho (author), Han, Sang Hui (author), Wardenier, J. (author)In this study, existing deformation limits are first re-examined to investigate if they can be rationally extended to high strength steel circular hollow section (CHS) joints that are subjected to in-plane bending (IPB) moment. It is pointed out that existing deformation limits, which have been developed and validated primarily for mild steel...journal article 2022

Lee, Yuan (author), Bersin, Eric (author), Dahlberg, E.A. (author), Wehner, S.D.C. (author), Englund, Dirk (author)The past decade has seen tremendous progress in experimentally realizing the building blocks of quantum repeaters. Repeater architectures with multiplexed quantum memories have been proposed to increase entanglement distribution rates, but an open challenge is to maintain entanglement fidelity over long-distance links. Here, we address this...journal article 2022

(author)Temporary postoperative cardiac pacing requires devices with percutaneous leads and external wired power and control systems. This hardware introduces risks for infection, limitations on patient mobility, and requirements for surgical extraction procedures. Bioresorbable pacemakers mitigate some of these disadvantages, but they demand pairing...journal article 2022

Park, S.Y. (author), Lee, Kyung Hoon (author)Data on the decision-making process of residential burglars at the micro-level are scarce. Furthermore, to the best of our knowledge, none of the related studies have investigated multiple relationships between the design features of a target, a burglar’s assessment of effort and risk involved in the crime, and the final decision on target...journal article 2022

Roy, S. (author), Lee, Jinoh (author), Baldi, S. (author)This brief proposes a new adaptive-robust formulation for time-delay control (TDC) under a less-restrictive stability condition. TDC relies on estimating the unknown system dynamics via the artificial introduction of a time delay, often referred to as time-delay estimation (TDE). In conventional TDC, the estimation error, called TDE error, is...journal article 2021
