Abstract:
A brain wave measuring method, a brain wave measuring apparatus, and a computer readable medium with a program for executing the method are provided to reduce a brain wave measurement time by reducing an operation degree in a process for removing noise due to heartbeat. A brain wave measuring method includes the steps of: extracting positive peaks and negative peaks from an EKG(Electrocardiogram) signal reflecting heartbeat information and extracting positive peaks from an EEG(ElectroEncephaloGram) signal reflecting noise information due to heartbeat and brain wave information(100); classifying the positive peaks of the EEG signal into a first peak group which is influenced by the heartbeat more than a brain wave and a second peak group which is influenced by the brain wave more than the heartbeat based on the positive peaks of the EKG signal(200); and removing noise due to the first peak group and the second peak group from the EEG signal(300).

Abstract:
The present invention provides a catalyst for decomposing nitrate nitrogen via reduction, wherein the catalyst includes a maghemite support and copper nanoparticles and palladium nanoparticles are supported on the support. The copper nanoparticles and the palladium nanoparticles may be present in a molar ratio of 10:1 or 1:10 and may be present respectively in 0.05 to 2% with respect to the total weight of the catalyst. Also the present invention provides a method for removing nitrate nitrogen via reduction using the catalyst having palladium and copper supported on the maghemite. If the catalyst according to the present invention is used, nitrate nitrogen can be removed very efficiently and decomposition selectivity into nitrate nitrogen is much more excellent than when using another support.
