Traditional practices and studies focused on sensing air quality by leveraging either fixed monitoring stations or dedicated mobile sensing equipment with expensive sensing costs. But recently, the vast distribution of the sensor-rich mobile devices carried by participants have made a new sensing paradigm possible, namely Mobile Crowdsensing. In this paper, we consider the inconsistency of sensing a sample in different subareas, combine compressive sensing and crowdsensing in the air quality applications, and correspondingly propose a cost aware crowdsensing framework for air quality sensing consisting of six stages: information modeling, cost estimation, cell selection, quality assessment, data inference and sensing data computing. Significantly, we present three cost aware task allocation strategies. Evaluations are conducted on real PM2.5 monitoring data-set. Our task allocation method based on the novel framework can remarkably reduce the inference errors with less sensing cost compared to the baselines, which demonstrates the performance of our proposed scheme.","PeriodicalId":336196,"journal":{"name":"Proceedings of the 6th ACM SIGSPATIAL International Workshop on Emergency Management using GIS","volume":"88 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114002556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Affected by the COVID-2019, almost all colleges and universities across the country have decided to postpone the start date. College students are characterized by a wide range of personnel sources, and many uncertain and complex factors on the way back. Therefore, Major universities should take measures to prevent and control the epidemic, and arrange for students to return to Campus under the premise of traveling in batches according to regional location and personnel characteristics. Geographic Information System (GIS) is a computer system used for collecting, storing, processing, analyzing, and displaying geospatial data, which provides important technical support for real-time epidemic transmission monitoring, emergency resource management, comprehensive social governance, public cognition, and other aspects. The purpose of this paper is to study the application of GIS in the formulation of measures for returning to Campus in colleges and universities under the epidemic situation, and to give a preliminary strategy for batching and staggered start of school.","PeriodicalId":336196,"journal":{"name":"Proceedings of the 6th ACM SIGSPATIAL International Workshop on Emergency Management using GIS","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132379575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the human contact data in a research institute of a university is collected using video surveillance devices, and the corresponding human contact network is constructed. On this basis, the structural characteristics of the human contact network are analyzed at the micro and macro levels respectively, and compared with the ER random network, WS small-world network and BA scale-free network. The results show that the human contact network cannot be accurately described by the three commonly used ideal networks, but it still has some structural characteristics of each ideal network. The contact network has more similarities in structure with the WS small-world network, including large clustering coefficient, modularity and average shortest path length, at the same time, it has more hierarchies and weak assortativity. This study can provide experimental support for the construction of network models in epidemic spreading dynamics, and is of great significance for the study of mechanism and control measures of epidemic spreading in complex networks.","PeriodicalId":336196,"journal":{"name":"Proceedings of the 6th ACM SIGSPATIAL International Workshop on Emergency Management using GIS","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129387711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
