In Malaysia itself, about 75% of newborns had jaundiced in the first week of life, this proves by the survey made by Ministry of Health Malaysia. Traditional assessment (Kramer's Rule) is not convenient since there are limits to the accuracy of visual estimation, thus blood test taken from baby's heel remains to be necessary but lead to traumatize to baby and their parents. Moreover the available jaundice meters in the market are expensive. This research work proposed the jaundice (hyperbilirubinemia) detection and prediction system using color card technique. It detects jaundice non-invasively by optical method (spectral reflectance method). This research doesn't involve any subject or infant. It collects data by capturing different type of color shades that represent random bilirubin color in patient's body, human skin color and bilirubin concentration color card using silicon photodiode sensor. This research concern about the human skin factor as it is the major disadvantages in most of the jaundice assessment. Thus, human skin colors represented by Fitzpatrick shades are considered. The final outputs were analyzed using linear regression analysis and characterized based on particular bilirubin value and treatment needed. The final outputs are shown in graphical user interface (Microsoft Visual Basic 2010) on medical staff's PC and can only be viewed by authorized person.","PeriodicalId":445522,"journal":{"name":"2017 IEEE 13th International Colloquium on Signal Processing & its Applications (CSPA)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116303626","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 is due to floods threaten human life and furthermore affected the economy of the involved country. In Malaysia, floods are usually due to the season monsoon and heavy rains that causing flash floods usually in urban area. Therefore, it is a must for researchers around the world to find a solution in solving this problem. A reliable and practical flood prediction model is in needs to predict flood occurrence ahead of time. Thus, this paper proposed the modelling of flood prediction model using NNARX (Neural Network Autoregressive with Exogenous Input) and hybrid NNARX with EKF (Extended Kalman Filter). The area of study was Klang River. The model was developed using real-time SCADA data that were acquired from the Department of Irrigation and Drainage, Malaysia. The model development was based on flood water level data in meter from 6 Feb. to 21 Nov. 2010. Modelling made used of 120 samples data, model validation using 78 samples data and model testing using 170 samples. The model performance of the NNARX-EKF hybrid model showed much better result than the NNARX model.","PeriodicalId":445522,"journal":{"name":"2017 IEEE 13th International Colloquium on Signal Processing & its Applications (CSPA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125719438","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}
