Probabilistic Forecasts of Storm Sudden Commencements From Interplanetary Shocks Using Machine Learning
Published 2020-11-01“…Several parameters, such as velocity and density, may be able to be more accurately predicted at a longer lead time, for example, from heliospheric imagery. When the input was limited to the velocity and density the models were found to perform well at forecasting SSCs, though with lower reliability than previously (BSSs ∼ 0.16, ROC Scores ∼ 0.8), Finally, the models were tested with hypothetical extreme data beyond current observations, showing dramatically different extrapolations.…”

Evolution of Dry/Wet Climate in Xichang from 1961 to 2016
Published 2022-01-01“…Regional climate analysis can optimize and supplement global climate research,and it is of vital significance for predicting regional climate changes and extreme weather.Based on the daily temperature and precipitation data from 1961 to 2016 in Xichang city,this paper systematically reveals the characteristics of temperature,precipitation,and dry and wet climate changes at annual and inter-annual scales by using the cumulative anomaly method,nonparametric trend analysis of time series (innovative trend analysis (ITA) method and ITA-change boxes (ITA-CB) method) and standardized precipitation evaporation index (SPEI).The results show that:① The distribution characteristics of annual temperature and precipitation in Xichang are similar,with the maximum value of both appearing in July.Moreover,the minimum temperature and precipitation appear in January and February,respectively.The average inter-annual and inter-decadal temperatures increase obviously,and the average inter-decadal precipitation improves slowly.② For the past 56 years,Xichang has witnessed apparent dry and wet climate changes.SPEI has dropped in a fluctuating tendency.In addition,it is negatively correlated with temperature (p<0.05) but positively correlated with precipitation (p<0.01).As temperature increases significantly,the drought degree has become more and more serious since 2003,and the negative value of SPEI accounts for 78.6%.The proportion of drought to extreme drought has increased to 28.6% in 2010.③ The average annual precipitation increases in low-value regions but decreases in high-value regions.The average annual temperature rises both in low-value regions and high-value regions and basically maintains an increasing tendency in median regions.SPEI increases in low-value regions but decreases in median and high-value regions.The research results can provide a reference for Xichang in dealing with climate change and formulating disaster prevention and mitigation plans.…”

Location privacy protection method based on lightweight K-anonymity incremental nearest neighbor algorithm
Published 2023-06-01“…The use of location-based service brings convenience to people’s daily lives, but it also raises concerns about users’ location privacy.In the k-nearest neighbor query problem, constructing K-anonymizing spatial regions is a method used to protects users’ location privacy, but it results in a large waste of communication overhead.The SpaceTwist scheme is an alternative method that uses an anchor point instead of the real location to complete the k-nearest neighbor query,which is simple to implement and has less waste of communication overhead.However,it cannot guarantee K-anonymous security, and the specific selection method of the anchor point is not provided.To address these shortcomings in SpaceTwist, some schemes calculate the user’s K-anonymity group by introducing a trusted anonymous server or using the way of user collaboration, and then enhance the end condition of the query algorithm to achieve K-anonymity security.Other schemes propose the anchor point optimization method based on the approximate distribution of interest points, which can further reduce the average communication overhead.A lightweight K-anonymity incremental nearest neighbor (LKINN) location privacy protection algorithm was proposed to improve SpaceTwist.LKINN used convex hull mathematical tool to calculate the key points of K-anonymity group, and proposed an anchor selection method based on it, achieving K-anonymity security with low computational and communication costs.LKINN was based on a hybrid location privacy protection architecture, making only semi-trusted security assumptions for all members of the system, which had lax security assumptions compared to some existing research schemes.Simulation results show that LKINN can prevent semi-trusted users from stealing the location privacy of normal users and has smaller query response time and communication overhead compare to some existing schemes.…”
