Therefore, in this paper, we propose a novel WIFI indoor location optimization approach based on position fingerprint algorithm. Each fingerprint contains a set of intensity values of the detected WAPs, and then it is defined as a vector with fixed size. The proposed location fingerprinting algorithm is made up of online and offline phase, in which generating the location fingerprint database is a crucial issue. Particularly, at the end of training process, a probabilistic map is generated for the interest area, and a single probability density function for the access point and the reference point are defined as well. Finally, we choose three smartphones with different hardware configurations on Android OS to conduct an experiment. Experimental results show that the proposed algorithm can effectively optimize the WIFI indoor location.","PeriodicalId":326442,"journal":{"name":"2017 International Conference on Smart Grid and Electrical Automation (ICSGEA)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121710935","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}

It will not only bring casualties and economic loss, but also affect traffic operation and result in congestion. Meanwhile, traffic jam will influence traffic safety. This paper collected 3973 accidents in Jianghan district of Wuhan in which there are many construction projects and extracted locations and times of traffic accidents. Spatial and time distributions of accidents were obtained by clustering statistics. The Relationship between traffic accident and congestion were established through regression analysis based on traffic congestion index and air temperature. Finally, the countermeasures to prevent traffic accidents were proposed.","PeriodicalId":326442,"journal":{"name":"2017 International Conference on Smart Grid and Electrical Automation (ICSGEA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124392185","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}

The relative elevation between two adjacent joints is taken as the input variable to deduce the mathematical expressions of the length variation of each member based on the mechanical equilibrium equation of structure formed in stages. Considering the characteristics of pre-camber setting of through steel truss girder bridge, the length variation formula of each member is further developed here in three cases: (1) changing the length of upper chord member bar only,(2) changing both the length of upper chord and diagonal wed member bar, and (3) changing the length of upper chords, diagonal wed and vertical member bar simultaneously. An example study is carried out to illustrate the application of the method. The analysis results show that the unstressed pre-camber setting method is an absolutely geometrical method, which will not generate stress in members and supports during the pre-camber setting. This method, of which the concept is clear and reliable, deserves being developed to be used in the other types of bridges.","PeriodicalId":326442,"journal":{"name":"2017 International Conference on Smart Grid and Electrical Automation (ICSGEA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115095182","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}
