摘要： The study evaluated the synergy between the indicators of rainfall,vegetation cover,land productivity in crop production,livestock production and the relationship between the value of aggregate agricultural production and the gross domestic product of municipalities in the semi-arid region of the State of Ceará,Brazil.The data sources are:CearáMeteorology and Water Resources Foundation(FUNCEME)and Brazilian Institute of Geography and Statistics(IBGE)for the years 1996,2006 and 2017.The research used the methodology of factor analysis(FA),with decomposition into principal components,to construct the index of agricultural production preservation(IAPP).The results showed that 1996 had the best rainfall levels and the highest IAPP values compared to the other years studied.Year of 2017 was the last one of a draught period that extended in Cearáfrom 2012 to 2017.In that year the lowest values for IAPP were observed.The main conclusion is:there was the expected interaction between rainfall and agricultural preservation indicators applied in the semi-arid region of the state of Cearáin the years 1996,2006 and 2017.

摘要： Introduction: No study has analyzed the reasons for the difference in HIV prevalence between Ivorian regions ranging from 1.3% in the central-western region to 4.1% in Abidjan among men. Objective: To analyze explanatory factors for the difference in HIV prevalence observed in men in Côte d’Ivoire’s regions. Methodology: Assessment of the relationship between HIV prevalence per region and risk factors explored in the 2012 Côte d’Ivoire Demographic and Health Surveys (DHS). A multivariate analysis was conducted to assess the relationship between HIV prevalence and each variable. Results: The explanatory power of the variation of HIV prevalence between regions was 98%. There was a significant association between HIV prevalence and union (r = ?0.38;p = 0.008;95% CI (?0.53 to ?0.23)), condom use (r = ?0.01;p = 0.19;95% CI (?0.03 to ?0.01)), practice of Christian religion (r = ?0.1;p = 0.017;95% CI (?0.16 to ?0.05)), and schooling (r = ?0.01;p = 0.25;95% CI (?0.04 to 0.02)). There was a paradoxical association between HIV prevalence and mean age at first sexual intercourse (r = ?0.1;p = 0.017;95% CI (?0.16 to ?0.05)) and sexual infections (r = ?0.48;p = 0.016;95% CI (?0.75 to ?0.22)). Conclusion: The explanatory factors for the difference in HIV prevalence observed in men in the regions of the country were union, condom use, mean age at first sexual intercourse, sexual infection, sexual activity, and multiple sexual partnerships. However, only union and condom use were effective in reducing HIV prevalence by preventing new infections.

摘要： Apache HBase(简称“HBase”)是基于Apache Hadoop(简称“Hadoop”)构建的一个高可用、高性能、多版本的分布式NoSQL数据库,是基于Hadoop系列技术的大数据平台重要组成部分,通过在廉价服务器上搭建大规模结构化存储集群,提供海量数据,实现高性能的随机读写能力。HBase将table分割成多个region,通过region的分裂、合并、迁移等操作实现其可扩展性、负载均衡、故障转移等特性。每个region将会存储row落在指定区间的数据,这些区间彼此是不重叠的,但是在长期运行过程中,由于种种原因,偶尔会有部分甚至大量的region区间出现重叠,这将导致对该区间的读写产生错误,这就是HBase Region Overlap问题。本文将就HBase 2.x以后的Region Overlap问题提出一种比较方便快捷的修复思路,并给出部分Java实现代码。

摘要： Load balancing is a technique for identifying overloaded and underloaded nodes and balancing the load between them.To maximize various performance parameters in cloud computing,researchers suggested various load balancing approaches.To store and access data and services provided by the different service providers through the network over different regions,cloud computing is one of the latest technology systems for both end-users and service providers.The volume of data is increasing due to the pandemic and a significant increase in usage of the internet has also been experienced.Users of the cloud are looking for services that are intelligent,and,can balance the traffic load by service providers,resulting in seamless and uninterrupted services.Different types of algorithms and techniques are available that can manage the load balancing in the cloud services.In this paper,a newly proposed method for load balancing in cloud computing at the database level is introduced.The database cloud services are frequently employed by companies of all sizes,for application development and business process.Load balancing for distributed applications can be used to maintain an efficient task scheduling process that also meets the user requirements and improves resource utilization.Load balancing is the process of distributing the load on various nodes to ensure that no single node is overloaded.To avoid the nodes from being overloaded,the load balancer divides an equal amount of computing time to all nodes.The results of two different scenarios showed the cross-region traffic management and significant growth in revenue of restaurants by using load balancer decisions on application traffic gateways.

摘要： [Objectives]To study the temporal and spatial variation of SOC content in cultivated land in black soil region in Liaoning Province.[Methods]Through the evaluation and analysis of the research data of this project and the data of the second national soil census,and using GIS technology,this paper studied the temporal and spatial variation characteristics of SOC in the black soil region of Liaoning Province,and provided a basis for improving cultivated land carbon storage and soil organic matter content.[Results]Since 1980,the SOC content in cultivated land in the black soil region in Liaoning Province has generally declined,and the spatial distribution difference has gradually decreased.From 1980 to 2018,the homogeneity of SOC distribution weakened,and the variation in a small range strengthened.The SOC content generally showed the characteristics of increase and decrease,and the changes in the area were scattered.[Conclusions]This study is of great significance to the sustainable utilization of land resources.

摘要： Nowadays,it has been in the period of rapidly developing China’s economy.Since the financial crisis in 2008,China has paid more and more attention to investing in fixed assets,and the growth rate of investing in fixed asset is also rising.However,when promoting regional economic growth,if we only pay attention to the total amount of fixed asset investment,there will inevitably exist some blindness and lack of sustainability.Therefore,the study between the investment structure of fixed assets and regional economic growth is quite important.China has a vast territory and many regions.The investment structure of fixed assets in different regions is also different,so the influence on economic growth is also different.This paper analyzes the investment structure of fixed assets and regional economic growth,and help realize the rapid growth of regional economy by recognizing the current situation of China''s investment structure of fixed assets.

摘要： To segment high-resolution remote sensing images(RSIs)accurately on an object level and meet the precise boundary dividing requirement,an improved superpixel segmentation and region merging algorithm is proposed.Simple linear iterative clustering(SLIC)is widely used because of its advantages in performance and effect;however,it causes over-segmentation,which is very disadvantageous to information extraction.In this proposed method,SLIC is firstly adopted for initial superpixel partition.The second stage follows the iterative merging procedure,which uses a hierarchical clustering algorithm and introduces a local binary pattern(LBP)texture feature operator during the process of merging.The experimental results indicate that the proposed method achieved a good segmentation and region merging performance,and worked effectively on cloud detection preprocessing in high-resolution RSIs with cloud and snow overlap situations.

摘要： Succession is one of the central themes of ecology;however,the relationship between aboveground plant communities and underground soils during secondary succession remains unclear.In this study,we investigated the composition of plant community,plant-soil C:N:P stoichiometry and their relationships during secondary succession after the abandonment of farmlands for 0,10,20,30,40 and 50 a in China,2016.Results showed that the composition of plant communities was most diverse in the farmlands after secondary succession for 20 and 50 a.Soil organic carbon and total nitrogen contents slightly decreased after secondary succession for 30 a,but both were significantly higher than those of control farmland(31.21%-139.10%and 24.24%-121.21%,respectively).Moreover,C:N ratios of soil and microbe greatly contributed to the changes in plant community composition during secondary succession of abandoned farmlands,explaining 35.70%of the total variation.Particularly,soil C:N ratio was significantly and positively related with the Shannon-Wiener index.This study provides the evidence of synchronous evolution between plant community and soil during secondary succession and C:N ratio is an important linkage between them.
