Reduction of Ocular Artifacts in Single Channel EEG by EEMD-IMF Thresholding
Abstract: AbstractElectroencephalogram (EEG) is a widely used signal for analyzing the activities of the brain and usually contaminated with artifacts due to the movements of eye, heart, muscles and power line interference. Among these ocular activities creates significant artifacts and makes the analysis difficult. In this paper, ensemble empirical mode decomposition (EEMD) inspired by wavelet thresholding is used for the correction of ocular artifacts (OA) in EEG signals. Unlike the conventional …

Evaluation of Surface Replication of Injection Molded Products Using a Diffraction Method
Abstract: ABSTRACT An evaluation method of surface replication for molded parts, which utilizes optical diffraction phenomena, is proposed. In general, the intensity of the diffracted light increases as the replication ratio becomes large, which leads to the increase in directly transmitted light. As a result, the surface in highly replicated region appears to be darker compared with the other region. An inversely proportional relationship between the 0th-order diffraction efficiency and the …
