Spectra of photoluminescence (PL), PL excitation, X-ray excited luminescence and pulse cathodoluminescence, thermally stimulated luminescence were measured. KLuP2O7:Pr3+ showed Pr3+ emission connected both with high intensity interconfigurational 4f15d1→4f2 transitions (UV bands in region of 250-320 nm), intraconfigurational 4f2→4f2 transitions (weak lines in vision spectral region) and Stocks defect-related luminescence. Upon both UV intra-center and band-to-band excitation with ionizing radiation, emission spectra of KLuP2O7:Pr3+ are dominated by Pr3+ interconfigurational 4f1 5d1→4f2 radiative transitions. Luminescence decay kinetics measurements established decay time τ ≈ 19 ns at room temperature. The study of thermally stimulated luminescence demonstrates effective light storage. Parameters of charge carriers’ traps were calculated: ΔE1 = 1.1 eV (for peak at 352 K) and ΔE2 = 1.3 eV (for peak at 388 K).","PeriodicalId":422750,"journal":{"name":"THE 2ND INTERNATIONAL CONFERENCE ON PHYSICAL INSTRUMENTATION AND ADVANCED MATERIALS 2019","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130779032","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}

This measuring instrument was composed of two components, namely NodeMCU microcontroller and infrared distance sensor. The measurement data is stored and displayed on the ThingSpeak website. To know the performance of the measuring instrument, conducted several tests. They are resolution tests, accuracy tests, short and long term stability test, and wireless communication between the instrument and server test. Based on the test result, obtained the resolution of the instrument was 2 mm, the accuracy has obtained the error of 2.34 mm by using the regression method and 0.34 mm by using a look-up table and interpolation method. The short stability reached above 95%. The standard deviation of the long term stability test was 0.157 mm, measured as much 100 times for 100 hours. Therefore, the measuring instrument successfully connects to the server and is able to send data properly.","PeriodicalId":422750,"journal":{"name":"THE 2ND INTERNATIONAL CONFERENCE ON PHYSICAL INSTRUMENTATION AND ADVANCED MATERIALS 2019","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114618921","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 purpose of this study is to obtain a more accurate diagnostic method so that it is expected to be used in reducing morbidity and mortality rated due to inappropriate and rapid handling of appendicitis. Research on the identification of acute appendicitis using Artificial Neural Networks has been conducted. In this study used 154 medical records of inpatients with acute appendicitis and not acute appendicitis from Airlangga University Hospital. The identification program is made by training and testing the program using Backpropagation Neural Network algorithm. The training conducted showed that there was a significant influence between the maximum iteration, the MSE limit, the number of hidden neurons, and the learning rate used on the final weights of the resulting network, thus greatly affecting the percentage of testing. The training and testing of the program carried out with various combinations of input parameters, shows that the best parameters that can be used in this program are: 1000 times the maximum iteration, MSE limit of 0.000001, learning rate of 0.1, and hidden neurons of 5, which with these parameters, the program succeeded in achieving accurate identification of test data up to 98.4375%. Based on the results that have been obtained, this method is expected to be useful for the progress of the diagnostic system, especially in cases of acute appendicitis.","PeriodicalId":422750,"journal":{"name":"THE 2ND INTERNATIONAL CONFERENCE ON PHYSICAL INSTRUMENTATION AND ADVANCED MATERIALS 2019","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131741408","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}
