Bibliometric Analysis of Low-carbon City Research Based on CiteSpace by LI Huimin, ZHANG Yu, LI Feng, CAO Yongchao

“…Low-carbon cities are considered to be the inevitable trend for current urban development.In order to systematically analyze the research status of low-carbon cities and point out the direction for future low-carbon research,this paper selects the relevant literature in the database of China National Knowledge Network and Web of Science and makes bibliometric analysis.The research status and development trend of low-carbon cities are grasped by analyzing the knowledge map and literature network relationship.The research points out that: ① Chinese research on low-carbon cities has been gradually carried out since 2008.It is expected that with the proposal of China's strategic goal of carbon peak and carbon neutrality,the carbon peak and ecological city may become the hotspot of global research on low-carbon cities in the future; ② the cooperation between Chinese and overseas authors and institutions needs to be strengthened,and cross-disciplinary research may gradually strengthen with the development of low-carbon city research; ③ the carbon peak time path of key industries,cross-regional carbon trading management mechanism,carbon emission quota,elimination of policy impact,carbon trading policy performance evaluation, and CCUS technology are urgent issues to be solved in low-carbon city research.This study provides a basis for the theoretical research and design practice of high-quality development of low-carbon cities.…”

Collusion node detection method based on fuzzy evaluation density clustering in Internet of vehicles by Haibo ZHANG, Dabin WANG, Ruyan WANG, Dongyu WANG

“…In order to solve the security problems caused by collusion of malicious vehicles in the open Internet of vehicles environment, a collusion node detection method based on fuzzy evaluation density clustering was designed.The method realized vehicle reputation update through subjective recommendation trust, objective data trust and historical reputation.Two rounds malicious node detection method was designed to detect malicious vehicles, in the first round, fuzzy comprehensive evaluation was used to screen out a single malicious vehicle node, and in the second round, the conspiracy malicious vehicle nodes were searched by the improved density clustering method according to a single malicious vehicle node to ensure the sustainable development of network environment security.Experimental results show that the proposed method has a high recognition rate for malicious vehicles, and when the proportion of malicious vehicles reaches 30%, the detection accuracy can still remain above 90%.At the same time, under the proportion of different malicious vehicles, the detection recall rate and detection F value still remain higher value, indicating that the proposed method has a high stability.For the change of total vehicle nodes, the performance evaluation index shows a small fluctuation and remain within the range from 80% to 100%.…”

Evolutionary Prediction of Soil Loss from Observed Rainstorm Parameters in an Erosion Watershed Using Genetic Programming by Kennedy C. Onyelowe, Ahmed M. Ebid, Light Nwobia

“…Three evolutionary trials were executed, and three models were presented considering different permutations of the predictors. The performance evaluation of the three models showed that trial 3 with the highest parametric permutation, i.e., that included the influence of all the studied parameters showed the least error of 0.1 and the maximum coefficient of determination (R2) of 0.97 and as such is the most efficient, robust, and applicable GP model to predict the soil loss value.…”
