IJGI | Free Full-Text | Assessment of Urban Resilience and Detection of Impact Factors Based on Spatial Autocorrelation Analysis and GeoDetector Model: A Case of Hunan Province

Sep 27, 2023 | mdpi.com | Jianhong Chen |Hongcai Ma |Shan Yang |Zhiyong Zhou

4. Results and Analysis 4.1. Time Differentiation 4.1.1. Comprehensive Resilience LevelThe urban resilience indexes of 14 cities in Hunan Province are obtained through the method in Section 3.3, as shown in Table 3. From 2010 to 2021, the resilience levels of 14 cities indicate a steady rise in general. The mean value of the urban resilience level also shows a steady upward trend in general in Figure 3. It rises steadily from 0.1824 in 2010 to 0.3708 in 2021, but shows a slight decline in 2012.
Risk Assessment of Mining Heritage Reuse in Public-Private-Partnership Mode Based on Improved Matter-Element Extension Model

Aug 20, 2023 | mdpi.com | Shan Yang |Zitong Xu |Jianhong Chen |Shengyuan Zhuo

3.2. Establishment of System of Risk-Evaluation IndicatorsThrough the questionnaire survey of the Likert five-point scale method [47], a total of 350 questionnaires were distributed, and 276 questionnaires were recovered at the end of the process, with a recovery rate of 78.9%, and the total final usable questionnaires after removing the invalid questionnaires were 263, with a validity rate of 75.1%.
Prediction of Rockburst Propensity Based on Intuitionistic Fuzzy Set-Multisource Combined Weights-Improved Attribute Measurement Model

Aug 14, 2023 | mdpi.com | Jianhong Chen |Yakun Zhao |Zhe Liu |Shan Yang

4.1. WorkflowsThe research content of this paper is to predict the degree of the propensity for rockburst occurrence through the composite model using intuitionistic fuzzy sets, multisource combined weights, and improved attribute measures. The research content of this paper is to predict the degree of the propensity for rockburst occurrence through the composite model using an intuitionistic fuzzy set–multisource combined assignment–improved attribute measure.

Tightly Coupled LiDAR-Inertial Odometry and Mapping for Underground Environments

Jul 31, 2023 | mdpi.com | Jianhong Chen |Hongwei Wang |Shan Yang

4. Results and DiscussionWe conducted an experimental evaluation of our algorithm on four datasets collected at the SubT Final Event held by DARPA in Louisville Mega Cavern. We compared our results with five state-of-the-art LiDAR or LiDAR-Inertial odometry methods: A-LOAM [10], Direct LiDAR Odometry (referred to DLO) [14], FAST-LIO2 [23], VoxelMap [29], and LiLi-OM [20].
