Device used to detect and record muscle electric pulses or signals is the electromyograph or EMG. EMG signals can be used in many applications, whether it has been recorded or displayed/analyzed in real time. Electromyographs (EMG) are rarely available in Indonesia. One of the causes of this rarity might be the high price of the EMG. This condition creates problems such as causing costly diagnosis or research. The goal of this research is to design a low cost, multi-channel microcontroller based EMG system, which can record and store EMG signals. The prototype shows promising result. The four channels can work accordingly, and portability of the prototype can be considered almost as a wearable prototype. Since connection to PC is only a single cable, the subject can position himself away from the PC, making a dynamic muscles recording possible. More works should be done if this prototype wants to be used in the clinical use.","PeriodicalId":191194,"journal":{"name":"International Conference on Instrumentation, Communication, Information Technology, and Biomedical Engineering 2009","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123295837","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}

Adapting this method on time-series prediction is done by using boosting algorithm. On boosting algorithm, recurrent neural networks (RNN) are generated, each for training on a different set of examples on time-series data, then the results for each of this base learners will be combined and resulting on a final hypothesis. The difference between our algorithm and the original algorithm is the introduction of a new parameter for tuning the boosting influence on given examples. Our boosting result is then tested on real time-series forecasting, using a natural dataset and function-generated time series. On the experiment result, it can be proved that ensemble method that we used is better than standard method, backpropagation through time for one step ahead time series prediction.","PeriodicalId":191194,"journal":{"name":"International Conference on Instrumentation, Communication, Information Technology, and Biomedical Engineering 2009","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114069211","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}

Its main energy source is coal coke. It is one of the oldest methods of producing cast iron, and it remains the dominate method because of its simplicity and low fuel cost. The size of Cupolas is 27 inch shell diameter, 4.5 inch thickness of lower lining, 18 inch diameter inside lining, and can produce up to 1 tons per hour of cast iron. Although cupola melting has a long history, Automatic control has been elusive because the process has been poorly understood. Most foundries rely on the intuition of experienced operators to make control decisions. The purpose of this work, which has been program, is to develop a controller for cupola using temperature control method. The temperature control method have two level control systems, there are system controller and process control. The system control takes input from the process operator about iron requirements such as iron temperature and composition. The process controller then acts to optimize economics by determining the set points that will produce the most efficient melting process. This project is used to the foundry company as plant of technology implementation control process with automatic control system.","PeriodicalId":191194,"journal":{"name":"International Conference on Instrumentation, Communication, Information Technology, and Biomedical Engineering 2009","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125329802","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}

All samples were treated for 15 minutes with 250 balls whose diameter of 1/8”, 3/16”, and 1/4\". The result shows enhanced surface roughness and reduced droplet contact angle of AISI 316L surface after SMAT. The ball's radius of curvature influences the pit geometry and the roughness of sample's surface. In addition, the performance of SMAT is still lacking to produce a hydrophilic surface.","PeriodicalId":191194,"journal":{"name":"International Conference on Instrumentation, Communication, Information Technology, and Biomedical Engineering 2009","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131486561","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}

Furthermore, the TE voice is low pitched, which presents a problem especially for female laryngectomized patients. A voice-producing element (VPE) is developed, based on the doublemembrane concept, to supply the laryngectomized patients with a better substitute voice. The VPE is comprised of two elastic membranes inside a circular housing that can be inserted in a shunt valve. Four identical prototypes were manufactured and tested in-vitro under physiological conditions. Prototypes were also tested in 17 female laryngectomised patients. An aerodynamic and acoustical analysis was performed, the maximum phonation time, speech rate and intonation capability determined. Finally the voice was perceptual evaluated. Basic sound, containing multiple harmonics, was successfully produced under physiologic air pressure and airflow conditions. The fundamental frequency and sound pressure level could be controlled by changing the driving pressure, thus enabling sufficient intonation. The obtained frequency range (190–350 Hz) is appropriate for producing a female voice. The VPE produced a sound with a low noise-to-harmonics ratio (mean 0.15), the efficiency of sound production (5.5⋅10−5) is comparable to normal vocal folds. The clinical study clearly showed that the pitch and sound intensity were increased without an unacceptable increase in driving lung pressure. The flow rates were lower than normal, leading to significantly longer phonation times. Accumulation of mucus did not interfere with speech production. In conclusion, functional restoration of the voice after laryngectomy with a VPE, based on the double-membrane concept, appears a feasible concept for female laryngectomized patients or patients with a hypo- or atonic PE segment.","PeriodicalId":191194,"journal":{"name":"International Conference on Instrumentation, Communication, Information Technology, and Biomedical Engineering 2009","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127598469","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}
