A 91-Channel Hyperspectral LiDAR for Coal/Rock Classification
Shao, Hui; Chen, Yuwei; Yang, Zhirong; Jiang, Changhui; Li, Wei; Wu, Haobo; Wen, Zhijie; Wang, Shaowei; Puttnon, Eetu; Hyyppä, Juha (Journal article; Peer reviewed, 2019)During the mining operation, it is a critical task in coal mines to significantly improve the safety by precision coal mining sorting and rock classification from different layers. It implies that a technique for rapidly ... -
A Screw-less Solution for Snake-like Robot Assembly and Sensor Integration
Li, Guoyuan; Verdru, Peter; Li, Wei; Zhang, Houxiang; Gomez, Juan Gonzalez (Chapter, 2017)Assembly or repair of snake-like robots are often time consuming and low efficiency. This paper presents a novel approach for module improvement that can efficiently integrate sensors, micro-controllers and batteries into ... -
Control of an Underwater Robot System Connected to a Ship by a Slender Marine Structure
Li, Wei (Master thesis, 2008)This report addresses the stabilization problem of a marine structure (i.e. cable/riser), connected to a surface vessel at one end and to a thruster unit at the other. Here, only motion in the lateral direction has been ... -
A Data-driven Explainable Case-based Reasoning Approach for Financial Risk Detection
Paraschiv, Florentina; Li, Wei; Sermpinis, Georgios (Peer reviewed; Journal article, 2022)The rapid development of artificial intelligence methods contributes to their wide applications for forecasting various financial risks in recent years. This study introduces a novel explainable case-based reasoning (CBR) ... -
Day-ahead electricity price prediction applying hybrid models of LSTM-based deep learning methods and feature selection algorithms under consideration of market coupling
Li, Wei; Becker, Denis Mike (Peer reviewed; Journal article, 2021)The availability of accurate day-ahead electricity price forecasts is pivotal for electricity market participants. In the context of trade liberalisation and market harmonisation in the European markets, accurate price ... -
Feasibility Study on Hyperspectral LiDAR for Ancient Huizhou-Style Architecture Preservation
Shao, Hui; Chen, Yuwei; Yang, Zhirong; Jiang, Changhui; Li, Wei; Wu, Haohao; Wang, Shaowei; Yang, Fan; Chen, Jie; Puttnon, Eetu; Hyyppä, Juha (Journal article; Peer reviewed, 2020)Huizhou-style ancient architecture was one of the most important genres of architectural heritage in China. The architecture employed bricks, woods, and stones as raw materials, and timber frames were significant structures. ... -
High concentrations of soluble endoglin can inhibit BMP9 signaling in non-endothelial cells
Andersson-Rusch, Clara Leticia; Liu, Bin; Quist-Løkken, Ingrid; Upton, Paul D.; Olsen, Oddrun Elise; Hella, Hanne; Yang, Xudong; Tong, Zhen; Morrell, Nicholas W.; Holien, Toril; Li, Wei (Peer reviewed; Journal article, 2023)Endoglin (ENG) is a single-pass transmembrane protein highly expressed on vascular endothelial cells, although low expression levels can be detected in many other cell types. Its extracellular domain can be found in ... -
Infinitely Many Embedded Eigenvalues for the Neumann-Poincaré Operator in 3D
Li, Wei; Perfekt, Karl-Mikael; Shipman, Stephen (Peer reviewed; Journal article, 2022)This article constructs a surface whose Neumann--Poincaré (NP) integral operator has infinitely many eigenvalues embedded in its essential spectrum. The surface is a sphere perturbed by smoothly attaching a conical ... -
A nomogram to predict survival probability of gastric cancer patients undergoing radical surgery and adjuvant chemotherapy
Ma, Ling; Chen, Guosheng; Wang, Deqiang; Zhang, Kai; Zhao, Fengjiao; Tang, Jie; Zhao, Jianyi; Røe, Oluf Dimitri; He, Shaohua; Liao, Dongcheng; Gu, Yanhong; Tao, Min; Shu, Yongqian; Li, Wei; Chen, Xiaofeng (Peer reviewed; Journal article, 2022)Gastric cancer (GC) is the third-leading cause of cancer mortality worldwide. The aim of this study was to develop a nomogram that estimates 1-year, 3-year, and 5-year survival probability of GC patients after D2 gastrectomy ... -
Spin noise spectroscopy of rubidium atomic gas under resonant and non-resonant conditions
Ma, Jian; Shi, Ping; Qian, Xuan; Li, Wei; Ji, Yang (Journal article; Peer reviewed, 2016)The spin fluctuation in rubidium atom gas is studied via all-optical spin noise spectroscopy (SNS). Experimental results show that the integrated SNS signal and its full width at half maximum (FWHM) strongly depend on the ... -
