Taoyuan, Taiwan

National Central University was founded in 1915 with roots from 258 CE in mainland China. After NCU in Nanjing was renamed Nanjing University in 1949, NCU was re-established in Taiwan in 1962. The school was initially located in Miaoli, but was relocated to Zhongli in 1968, and developed into a comprehensive university. It has now become Taiwan's leading school in the fields of drama, film studies, cultural studies, sex and gender studies, Hakka studies, geophysics, space science, remote sensing, astronomy, optoelectronics, nano scitech, and business management. In 2001, NCU was selected by the Ministry of Education as one of the eleven research-oriented universities in Taiwan.NCU now has eight colleges in different areas, including College of Liberal Arts, College of Science, College of Engineering, College of Electrical Engineering and Computer Science, College of Biomedical Science and Engineering, College of Earth science, College of Management, and College of Hakka Studies, also with areas in sociology, law and government studies, etc. Wikipedia.

The invention provides a method for electric brain stimulator. In the beginning, obtaining a brain functional amplitude modulation spectrum, wherein the brain functional amplitude modulation spectrum is a relationship between carrier frequency and amplitude-frequency on different brain sites. Then selecting a first alternating current frequency, wherein the first alternating current frequency is determined by the amplitude-frequency in which the brain functional amplitude modulation spectrum display a maximum power relation value, or a maximum correlation value with any behavior index of behavior and cognitive functions. And selecting a second alternating current frequency, wherein the second alternating current frequency is determined by the carrier frequency in which the brain functional amplitude modulation spectrum display a maximum power relation value, or a maximum correlation value with any behavior index of behavior and cognitive functions. In the end, outputting an alternating current signal, the alternating current signal is generated based on a first cosine function of the first alternating current frequency, a second cosine function of the second alternating current frequency, or a combination of the first cosine function and the second cosine function.


The invention discloses a method and a system for quickly and directly processing an original signal into a plurality of mode functions, the steps comprises: decomposing the original signal by Empirical Mode Decomposition (EMD) method to choose a first intrinsic mode functions (IMFs). Then, adding the plurality of level n conjugate masking functions, which are selected from a group of sinusoidal functions comprising the mean amplitude and the mean frequency of the first IMF, to the original signal individually to obtain level n mode functions, until the level n mode function is a monotonic function, wherein the plurality of mode functions are the IMFs between each frequency regions of the original signal. The invention not only includes the advantage of EMD analyzing, but also excludes the problem of mode mixing phenomenon which is caused by the intermittent disturbance.
