Wu, Jingxuan (author), Li, Shuting (author), Gui, Yonghao (author), Cvetkovic, M. (author), Vasquez, Juan C. (author), Guerrero, Josep M. (author)A fuzzy logic based online energy management system (FLEMS) is designed in this paper to achieve the optimal electricity cost in a residential Microgrid (MG). The proposed FLEMS is combined by a local energy price model (LEPM) and a fuzzy-logic strategy. The LEPM will preprocess the sampling data to estimate the electricity market and local MG...conference paper 2023

Li, C. (author), Hendriks, R.C. (author)Spatial filtering techniques typically rely on estimates of the target relative transfer function (RTF). However, the target speech signal is typically corrupted by late reverberation and ambient noise, which complicates RTF estimation. Existing methods subtract the noise covariance matrix to obtain the target plus late reverberation covariance...conference paper 2023

Zeng, Y. (author), Nunez, Alfredo (author), Li, Z. (author)Due to train load and aging, the dynamic properties of railway tracks degrade over time and deviate over space, which should be monitored to facilitate track maintenance decisions. A train-borne laser Doppler vibrometer (LDV) can directly measure track vibrations in response to the moving train load, which can be potentially applied to large...conference paper 2023

Xu, Li (author), Li, T. (author), Erkin, Z. (author)Verifiable Credential (VC) is a new standard proposed by the W3C association to facilitate the expression and verification of third-party-verified credentials on the Internet, such as passports or diplomas. However, the current VC data model lacks an explicit revocation design that guarantees the secure operations of the system, which limits its...conference paper 2023

Li, L. (author), Bruninx, K. (author), Tindemans, Simon H. (author)This paper proposes a multi-level segmented tariff to encourage consumers to provide demand response using a battery. The aim of the tariff is to (i) properly reflect consumers’ contribution to the distribution grid cost while ensuring cost recovery for the distribution network operator and (ii) to provide consumers with a financial incentive to...conference paper 2023

Li, Qiongxiu (author), Lopuhaä-Zwakenberg, Milan (author), Heusdens, R. (author), Christensen, Mads Græsbøll (author)Both communication overhead and privacy are main concerns in designing distributed computing algorithms. It is very challenging to address them simultaneously as encryption methods required for privacy-preservation often incur high communication costs. In this paper, we argue that there is a fundamental link between communication efficiency...conference paper 2022

(author), Nunez, Alfredo (author)In this paper, a fuzzy interval-based method is proposed for solving the problem of rail defect detection relying on an on-board measurement system and a multiple spiking neural network architecture. Instead of outputting binary values (defect or not defect), all data will belong to both classes with different spreads that are given by two fuzzy...conference paper 2022

Bolijn, Hidde (author), Li, Martin (author), Reurink, Andries (author), van Rijn, Cas (author), Bidarra, Rafael (author)Many people think of reforestation projects as one-dimensional, simply consisting of planting trees. In reality, a reforestation project takes into account a wide variety of factors, of which the three most important are improving soil quality, reducing fire hazard, and ensuring the prosperity of the community. We posit that a simplistic view on...conference paper 2022

Kawasaki, S. (author), Yeh, Jia-Jun (author), Saccher, M. (author), Li, Jian (author), Dekker, R. (author)The main limitation of acoustic particle separation for microfluidic application is its low sorting efficiency. This is due to the weak coupling of surface acoustic waves (SAWs) into the microchannel. In this work, we demonstrate bulk acoustic wave (BAW) particle sorting using capacitive micromachined ultrasonic transducers (CMUTs) for the first...conference paper 2022
