This paper describes a method by which a KOH (Potassium Hydroxide) etchant is utilized for the pattern formation on the surface of the quartz crystal sensor. The etching process is preferable in order to produce a flat surface roughness. The etchant concentration affects etching rate and surface roughness. In this experiment, the effect of etchant concentration on the etching rate and surface roughness was investigated. The etching of the quartz crystal was carried out using KOH concentration of 25 %, 30% and 35 % by weight at a temperature of 80°C for 2 hours. Aurum palladium (AuPd) was used as a mask to protect the rest of the quartz crystal. The AuPd mask was coated on the quartz crystal by a sputter coater in a high vacuum chamber. The etched surfaces were observed using a white light profilometer TMS 1200. The results show that best anisotropic patterns formation were obtained in 30% wt KOH solution. Furthermore, the TMS indicates that the surface roughness of the etched surface tends to increase with the increasing of KOH concentration.","PeriodicalId":118419,"journal":{"name":"2016 International Seminar on Sensors, Instrumentation, Measurement and Metrology (ISSIMM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125314140","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 sensitivity of the quartz crystal microbalance is not only depended on the resonance frequency of the sensor but also the resolution of the counter. Higher counter resolution results in higher sensitivity measurement of the sensor output. In this work, a three-channel reciprocal frequency counter was developed using FPGA and implemented using VHDL code. The precision and resolution of the system depend on the system clock source. In this development, a high-precision TCXO oscillator with a resonance frequency of 100MHz is used as a reference oscillator. From this oscillator, one-second time gate and period measurement is constructed in the FPGA. In each measurement channel, dual digital counters were implemented. One counter counts the incoming signal in between one-second gate, and the other counter is counting the 100MHz signal from the beginning to the end of the counted signal within the one-second gate. The accuracy of the frequency measurement of the counter was calibrated using 10MHz standard rubidium oscillator. The developed system shows a good performance and able to count incoming signal with an accuracy of 0.1 Hz for one second acquisition time.","PeriodicalId":118419,"journal":{"name":"2016 International Seminar on Sensors, Instrumentation, Measurement and Metrology (ISSIMM)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123010577","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}

One of the diabetes complications that affect the retina is known as diabetic retinopathy (DR). It is indicated by the presence of hard exudates as the main pathology of DR. In retinal fundus images, hard exudates appear as bright lesion which has some similar characteristics with the optic disc. This paper proposes a method to automatically detect hard exudates. At first, the green channel is extracted from the retinal colour fundus image. The complement of green channel is used to increase the contrast between hard exudates and the background. The complemented image is filtered by using matched filter. Optic disc (OD) is detected based on initial optic disc enlargement in L band of HSL colour space. Afterwards, optic disc is removed from filtered image to obtain the candidates of hard exudates followed by the morphological operation. The proposed method is validated by using 60 colour fundus images from DIARETDB1 dataset. The final results of segmented exudates are verified by comparing with their ground truth images. The average level of accuracy, sensitivity and specificity achieved are 99.99%, 90.38% and 99.99%, respectively. These results indicate that the proposed method successfully detected the hard exudates. Hence, it is recommended to be implemented as a part of DR grading system development.","PeriodicalId":118419,"journal":{"name":"2016 International Seminar on Sensors, Instrumentation, Measurement and Metrology (ISSIMM)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128020626","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}

On the other sides, the emissions contribute to high pollutants in the air. In terms of PM2.5 emissions affect on human health. However the data of PM2.5 emitted by motorcycles are unavailable, and the relationship between PM2.5 containing in the motor smokes and the impacts on human health is also unknown. This study was aimed to investigate the impacts of PM2.5 in the motor cycle smokes on mice/s lung damages by conducting measurements of varied PM2.5 concentrations exposed to mice and observing the mice lung damages. The measurements of PM2.5 concentrations in the smokes were conducted by introducing motor cycle smokes in a chamber with the dimension of 30×20×20 cm3 with a pump with the varies of time. The PM2.5 concentrations were measured using a Kanomax 3443 Digital Dust Monitor. Investigation of the impacts PM2.5 on mice lung were carried out by placing mice in the chamber for smoke exposures with the varied concentrations of PM2.5 in the smokes for 100 s twice a day. The measurements of the mice lung damages were carried out by observing the normal and abnormal alveolus using a Binocular CX-31 Computer Microscope with 400x magnification after the mice experienced smoke exposures for two days. The results showed that longer time of introducing smokes in the chamber resulted in higher concentrations of PM2.5. The measured concentrations are found varied between 1.2 and 19.3 mg/m3 depending on the operating time and the motor sample. Higher concentration of PM2.5 in the smokes exposed to the mice caused more damages of the mice lung. The correlation is obtained in the second order polynomial function with the R2 > 0.9.","PeriodicalId":118419,"journal":{"name":"2016 International Seminar on Sensors, Instrumentation, Measurement and Metrology (ISSIMM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131088232","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 may cause a voltage drop and other impact related to power losses because of the limited availability of reactive power source in the system. Therefore, implementation of compensation devices such as capacitor bank, Static VAR Compensator (SVC), and other Flexible AC Transmission System (FACTS) devices to inject reactive power to the network are needed. The optimum location and size of the compensation device must be determined appropriately. This paper presents two optimization approaches, including both deterministic and nondeterministic methods. Artificial bee colony (ABC) algorithm is applied to acquire the most optimum size and location of SVC. It is an optimization method using metaheuristic techniques which have been developed based on the intelligent behavior of honey bee. The IEEE standard 30-bus system data has been used to determine the performance of the ABC algorithm to control the voltage profile and power losses. Comparison of the voltage profile and power losses without and with an injection of SVC of the power system has been determined by using the ABC algorithm optimization method. Based on the analysis results, it was known that the SVC optimization could boost the voltage profile at all buses under consideration to the value higher than its minimum allowed voltage. Besides, the power losses condition has also been improved, with 35.36% active power improvement and 40.90% reactive power improvement subsequently.","PeriodicalId":118419,"journal":{"name":"2016 International Seminar on Sensors, Instrumentation, Measurement and Metrology (ISSIMM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122607971","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}
