This paper describes the development of a gas-solids flow measurement setup with a suitable ultrasound Doppler flow meter used for teaching purposes. Main aim of the setup is to provide students a substantiated practical knowledge in the fields of pneumatic conveying of bulk solids and the measurement of gaseous and particulate velocities in two-phase(More)
Automatic EEG-processing systems such as seizure detection systems are more and more in use to cope with the large amount of data that arises from long-term EEG-monitorings. Since artifacts occur very often during the recordings and disturb the EEG-processing, it is crucial for these systems to have a good automatic artifact detection. We present a novel,(More)
This paper describes the development of a gas-solid flow measurement setup based on an optical method to determine the particle velocity in granular material flow. Main aim of the setup is to provide students a substantiated practical knowledge in the fields of pneumatic conveying of bulk solids and the measurement of gaseous and particulate velocities in(More)
A parameter optimization method for an automatic seizure detection algorithm using the Nelder Mead algorithm is presented. A suitable cost function for joint optimization of sensitivity and false alarm rate is proposed. The optimization is done using EEG datasets from 23 patients and validated on datasets from another 23 patients. The resulting sensitivity(More)
