The relation between physical characteristics of the flute, such as acoustic length, playing hole, temperature effect, etc., and the frequency of each musical note of khluis is investigated. First, the fundamental frequencies of each finger hole of 10 khluis are measured. Then, data between the ideal musical notes and measured notes of khlui are analysed. The results indicate that the production process of khlui still has limits in accuracy. Finally, in order to develop a production standard of the Thai duct flute, a model of khlui is designed. The musical notes of the designed flute are measured. The accuracy of the designed flute is investigated to support the understanding of its acoustical model.","PeriodicalId":224375,"journal":{"name":"2020 6th International Conference on Engineering, Applied Sciences and Technology (ICEAST)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129145337","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 oil samples (i.e., mineral oil, natural ester, and palm oil) were prepared for experiments. The oil samples were dried at 70 °C under 200 mbar in the controlled temperature oven and then cooled down to ambient temperature. The moisture contents of the oil samples were measured according to ASTM D1533. The test cell, according to IEC61620, was employed in these measurements. The polarization currents, ipol(t), of such oil samples under electric field stress of 0.2 kV/mm with a temperature range from 30 to 70 °C were measured, The test results are summarized in this paper. The step response measurement results were analyzed for conductivities, permittivity, and loss factor value. It was found that increasing temperature causes increasing conductivities but decreasing permittivity of oil samples.","PeriodicalId":224375,"journal":{"name":"2020 6th International Conference on Engineering, Applied Sciences and Technology (ICEAST)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133780377","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 tuning laws of the natural angular frequency (ωo) and the quality factor (Q) are non-interactive electronic control by changing the external bias current of LT1228s.
