A procedure for modeling two types of signals, corresponding to the radiometric sounding of moving cloud field is suggested. The first one: one-dimensional signals, describing observation with infrared radiometer of non-homogeneous cloud field moving with constant drift velocity without time evolution. The second one: one-dimensional signals, describing the observation of non-stationary and non-homogeneous objects, constructed accounting for the possibility to present the meteorological field time evolution as a superposition of traveling plane waves. On their basis the possibilities and the accuracy of both methods are compared. Numerical examples, illustrated by graphic material, have been shown.","PeriodicalId":306452,"journal":{"name":"2019 IEEE XXVIII International Scientific Conference Electronics (ET)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123204147","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}

Furthermore, as the application to electric vehicles is expanding, the battery cost is also decreasing. Therefore, LiB is also expected to be used for power leveling applications. Therefore, when LiB is connected to the grid, it is necessary to consider the possibility of high voltage pulses such as induced lightning being applied to LiB. We clarified that a current of 10000 C or more flows to LiB instantaneously when applying a high voltage pulse for a short time. Furthermore, it was reported that the decrease of the battery capacity did not occur when the pulse was applied for a short time. We reconfirmed the result. The current in LiB was analyzed assuming an equivalent circuit. It was found that when a short time pulse was applied, most of the current flowed to the electric double layer present at the interface between the electrode and the electrolyte, and hardly flowed to the reaction resistance corresponding to the electrochemical reaction. Furthermore, we examined the voltage and pulse width of the pulse which has a high possibility of affecting the battery capacity.","PeriodicalId":306452,"journal":{"name":"2019 IEEE XXVIII International Scientific Conference Electronics (ET)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131801579","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}
