The proposed signal transmitter is used to transmit the standard signals for testing and verifying the functionality of factory automation and process control systems in an industrial environment. The standard 4–20 mA current signal is provided in the designed signal transmitter. Additionally, some standard voltage signals are available to enable the flexibility in practical utilization. The voltage outputs can be transmitted within three ranges including 0–5 V, 0–10 V and 1–5 V. The proposed signal transmitter is designed utilizing an open-source electronics prototyping platform Arduino Nano ATMEGA328P microcontroller. Analog to Digital converter (ADC) ADS1115 is used in the transmitter with 16-bit resolution. Digital to Analog converter (DAC) MCP4922, which is dual channel with 12-bit resolution, is used for providing high accuracy output signal levels together with low noises performance. Furthermore, the current gain is used via the operational amplifier TLC 2272 exhibited rail-to-rail output performance. The main portion of signal transmitter is integrated within a small container that offers a portability of the device for field testing. The proposed industrial standard mixed-signal transmitter is tested to investigate the functionality and performance of the device in various experiments. The experimental results evidently demonstrate the complete designated functionality and satisfactory performance based on the existing conventional signal transmitter with low-cost solution.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"111 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80647735","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 virus is transmitted by mosquitoes. Dengue can also be transmitted via infected blood products and through organ donation. There are many infected people in each year. Thus, if the number of patients can be predicted, vaccines for dengue fever will be able to prepare for serving all patients in that area. This research proposed a two-step prediction method that combines time series forecasting analysis and supervised learning techniques to predict the number of dengue fever patient cases. In generally, the result of prediction from only the number of patient cases is not good enough for application; accuracy and confidence are low. In this research, the environmental factors are considered and predicted. Then, these factors are used for predicting the number patient cases. The experimental results show that the proposed two-step prediction technique is a good choice for dengue fever prediction. The accuracy is better than the simple prediction technique.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"12 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90233821","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}

In order to achieve optimum values of simulated intrinsic parameters, an objective function based on experimental data for both phase and magnitude is defined. The device intrinsic small signal parameters are then evaluated by using the simulated data. By using particle swarm optimization, different gains of the device and insertion loss are also taken into account which helped in formulating a good agreement between simulated and experimental data.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"30 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89595597","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}

Three noniterative estimators of heterogeneity variance priors for SMRs as dispersion measures among areas are compared to produce the best fitting model and map. The data source of the number of newly diagnosed HIV/ AIDS cases infected out of the persons who come to receive medical treatments including blood test is provided by the National AIDS Program (NAP), collected by the National Health Security Office (NHSO). The results showed that the first heterogeneity variance prior estimate derived from the marginal variance estimator of observed number of HIV/AIDS cases performs best with the smallest deviance information criterion (DIC), the largest log-marginal-likelihood, and the highest posterior probability, leading to a suitable map with five high risk classes of SMR classification under Bayesian mapping. Practically, the prior information on the mean is the most popular use to improve Bayes estimates; however, a recommendation based upon an acceptable prior on the heterogeneity variance after controlling the same mean prior from this study result is also adopted as an alternative choice.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"3 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89880021","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}

With the same feed voltage the pattern has been obtained in FEKO to observe the effect of mutual coupling. Finally, the coupled gain pattern has been obtained with the compensated feed voltage.

Therefore, a battery monitoring is a key function in a charger to check battery condition; however, a traditional charger used in a substation does not have this function. A lead acid battery first order equivalent circuit is utilized to analyze the battery condition by probing an internal resistance of a battery. A first order equivalent circuit is used to determined battery parameters using transient response analysis. PSIM is also used to simulate the proposed equivalent circuit properties comparing to experimental result. The experimental results are conducted by using three lead acid batteries which are used in a PEA substation.
