The stemming is tightly related to basic word or lemma and the sub lemmas. The lemma and sub lemma of Indonesian Language have been grown and absorb from foreign languages or Indonesian traditional languages. Our approach provides the easy way of stemming Indonesian language through flexibility affix classification. Therefore, the affix additional can be applied in easy way. We experiment with 1,704 text documents with 255,182 tokens and the stemmed words is 3,648 words. In this experiment, we compare our approach performance to the confix-stripping approach performance. The result shows that our performance can cover the failure in stemming reduplicated words of confix-stripping approach.","PeriodicalId":200661,"journal":{"name":"2016 13th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116026952","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 firmwares are particularly designed and implemented for real-time measurement, analysis and control applications. They are developed with C language to archive better performance. A C-file of the microcontroller is compiled by the XC16 compiler to generate a HEX-file. While a C-file of the Matlab-Simulink is written as standard s-function of the Matlab and then compiled by Visual Studio 2013 using MEX command in Matlab workspace to generate a MEX-file. A Matlab-Simulink application uses the MEX-file as a core function for exchanging data with the microcontroller. Both of the firmwares are implemented based on Event-driven and Queue-driven techniques to maintain real-time ability and to guarantee that all data flowing over UART (RS-232) are transmitted, received and processed on time. To test and evaluate the firmwares, we develop 4-Channel Data Acquisition (DAQ) and 4-Channel PWM Signal Generator (PSG) running on the microcontroller. And in the Matlab-Simulink, an application for visualizing the signals of the DAQ and controlling the signals of the PSG is developed. The experimental results obviously show that the firmwares can be used for computer-based measurement, analysis and control applications properly.","PeriodicalId":200661,"journal":{"name":"2016 13th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121277315","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}

Graphene is single atom thick layer of graphite which consists of carbon atoms that are bonded together in a hexagonal honeycomb lattice. A way of fabricating suspended graphene is presented. Graphene grown on copper (Cu) foil using chemical vapour deposition (CVD) method is used for transference on silicon wafer with etched holes on top. Graphene is transferred on the silicon using Poly (methyl methacrylate) (PMMA) method and the analysis is done using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The suspended graphene is quite uniform and the results show that it is a promising approach for suspended graphene, however, considerable effort is needed for the development of the transference and fabrication process.","PeriodicalId":200661,"journal":{"name":"2016 13th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133867344","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}

Up to this approach, it can support either single-phase condition or two-phase condition. Performance of the proposed control strategy was verified by the simplified simulation model in the MATLAB/Simulink software. It is clearly shown that the matrix converter can be controlled for regulating the balanced output voltages with showing good steady-state and dynamic operations without the energy storage devices.","PeriodicalId":200661,"journal":{"name":"2016 13th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130962281","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 observed foF2 results show a similar feature in diurnal and seasonal variations with higher during daytime, lower during nighttime. The maximum values occur during equinox (March and September) seasons while the minimum levels occur in solstice (June and December) seasons.
