Real-Time Monitoring of Cognitive Workload of Airline Pilots in a Flight Simulator with fNIR Optical Brain Imaging Technology
Çakır, Murat Perit; Koc, Suleyman Ozgur; Toktas, Ahmet (2016-07-22)
Real-time monitoring of the flight crew's health status with ambient and body sensors have become an important concern to improve the safety and the efficiency of flight operations. In this paper we report our preliminary findings on a functional near-infrared spectroscopy (fNIR) based online algorithm developed for real-time monitoring of mental workload of an airline pilot. We developed a linear discriminant analysis (LDA) based classifier that aims to predict low, moderate and high mental workload states...
Real-time monitoring of indigo concentrations in the dyebath with a laser diode spectrometer
Sahin, U; Ulgen, A; Kekec, A; Gökmen, Ali (SAGE Publications, 2004-03-01)
A laser diode absorption spectrometer is coupled with a continuous dilution system for real-time monitoring of indigo dyeing of denim yarn. The reduced form of indigo in the dyebath is continuously pumped by a peristaltic pump into a mixing cuvette, where it is diluted by a factor of 80 with aerated water and oxidized into its stable form. This solution is then pumped into the sampling cell of the laser diode spectrometer for absorption measurements. Monochromatic radiation emitted from the laser diode at 6...
Real-time detection and tracking of human eyes in video sequences
Savaş, Zafer; Halıcı, Uğur; Department of Electrical and Electronics Engineering (2005)
Robust, non-intrusive human eye detection problem has been a fundamental and challenging problem for computer vision area. Not only it is a problem of its own, it can be used to ease the problem of finding the locations of other facial features for recognition tasks and human-computer interaction purposes as well. Many previous works have the capability of determining the locations of the human eyes but the main task in this thesis is not only a vision system with eye detection capability; Our aim is to des...
Real-time traffic sign detection and recognition on FPGA
Yalçın, Hüseyin; Bulut, Mehmet Mete; Akar, Gözde; Department of Electrical and Electronics Engineering (2013)
In this thesis, an embedded system for traffic sign detection and recognition is proposed. Proposed system is first designed in MATLAB and optimized. After optimization process, system design is transferred to FPGA and Virtex-V FX70 FPGA is selected for implementation platform. 640x480 sized image in RGB format is sent to FPGA system via computer interface. This image is segmented for red, blue, and yellow colors. Red and blue color maps are divided into 8x8 sub-blocks. Yellow color map is divided into 32x3...
Real-time measurement of laser beam characteristics for a waterjet-guided laser machine
Subasi, Levent; Gökler, Mustafa İlhan; Yaman, Ulaş (2022-01-01)
© 2022, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.Waterjet-guided laser machining is a novel process used for precision cutting and drilling of various materials and geometries. There are many noise factors in the process affecting the laser beam characteristics, namely the effective cutting length and laser power in the waterjet. Although these variables are mainly set by the laser and waterjet parameters, uncontrollable factors result in variations. Pre...
