In the past few decades, biomedical signals have played important roles in assisting diagnosis for medical purposes. After the rose of brain-computer interfaces (BCI) and human-machine interaction (HMI) concept, biomedical signals such as an electroencephalograph (EEG) and electrooculogram (EOG) begun to be implemented in control and communication systems. EOG, [...]

This research was conducted to develop a method to identify voice utterance. For voice utterance that encounters change caused by aging factor, with the interval of 10 to 25 years. The change of voice utterance influenced by aging factor might be extracted by MFCC (Mel Frequency Cepstrum Coefficient). However, the level of the compatibility of [...]

Detection and recognition of object movements in a video is one of the research topics that are popular today. For the purposes of the analysis of the object movements in the video, the direction of movement is the important feature. In this study, we proposed a new method for determining the direction of movement using [...]

It has been determined the best mother wavelet for stock prediction of SONY 2006 and BNI 2012 based on the Adaplet Method (The Adaptive Filter which is use wavelet as initial coefficients). The Mother Wavelets, which is used, are Coiflet 1-5, Daubechies 1-5, and Symlet 1-5. The prediction analysis includes overshoot, autocorrelation error and data [...]

Kebutuhan penggunaan korpus yang menggunakan bahasa Indonesia semakin meningkat akan tetapi kebutuhan tersebut belum didukung dengan tersedianya korpus berbahasa Indonesia. Banyak negara sudah memiliki korpus nasional seperti British National Corpus (BNC), American National Corpus (ANC) dan lain sebagainya. Proyek pembuatan Korpus Nasional Bahasa Indonesia (KNBI) sendiri pernah disinggung dalam laporan akhir tahun anggaran 2001 proyek [...]

This paper discusses the usage of short term energy contour of a speech smoothed by a fuzzy-based method to automatically segment the speech into syllabic units. Two additional procedures, local normalization and postprocessing, are proposed to improve the method. Testing to Indonesian speech dataset shows that local normalization significantly improves the accuracy of fuzzy smoothing. [...]
