A model is developed that explains the effect of intensity and duration of microwave energy impact on the change of germination energy, germinating ability and productivity of grain crops using an example of successive changes in the chain of associated water - amylase - maltose - glucose depending upon the initial grain moisture content. A method of seed treatment of vegetable crops has been developed which ensures the rate of growth, which is important for vegetable farming in greenhouses. Results of increasing germinating ability of melon seeds from 10% to 83% after microwave effect are of practical interest.","PeriodicalId":283310,"journal":{"name":"2015 International Conference on Antenna Theory and Techniques (ICATT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125298486","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}

So, it is very important to develop a system that detects an approach of drowsiness and awakes a driver in a case of alarm. The method of detection of drowsiness based on analysis of ECG parameters is convenient and informative enough. A problem of monitoring a driver's state by controlling his heart rate is actual because this parameter is simple to register. But a threshold of drowsiness can vary for different people. So, it is necessary to control some additional parameters. Research of how parameters of heart rate variability (LF/HF and index of stress of Bayevsky) change in time depending on a state person (during wakefulness, drowsiness and stress) has been carried out. The results showed that there are certain intervals of values characterizing each kind of state. To sum up, it's suggested to use the analysis of three ECG parameters (HR, LF/HF and index of stress of Bayevsky) in drivers' drowsiness detecting systems. Using a GPRS data transmission system allows to realize processing and storage of ECG information on a powerful server.","PeriodicalId":283310,"journal":{"name":"2015 International Conference on Antenna Theory and Techniques (ICATT)","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131435218","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}
