The paper proposes the method of using image processing to determine the distances between autonomous vehicle, where stereo vision is installed, and the observed objects. Purposely, a stereo camera Minoru is used. The stereo camera uses two different 2D images, which are the two horizontally different views of the same object, to get the depth information. The complete process includes of three steps which are image acquisition, camera...

A mean threshold algorithm is proposed to detect eye activities using ElectroEncephaloGraphy (EEG) technique in this paper. The activities of eyes such as blinking two eyes, left eye and right eye related to the delta area of human brain are investigated. Before analyzing the EEG data, original data are filtered to reduce noise or artifacts by a band-pass filter. The proposed threshold method is applied to distinguish the phenomenon of eye...

Ultrasound-assisted convective drying is a green and sustainable technology that offers an interesting way to improve dehydration rate in agriculture products processing due to a low heating effect, and increase the quality of the preserved food. In comparison to other traditional drying technologies, this method has been proven to have the energy savings potential. A number of high-power ultrasonic transducers with extensive radiators have...
