This paper presents the results of the scientific investigations which aimed at developing the detectors of the selected driver fatigue symptoms based on face images. The presented approach assumed using convolutional neural networks and transfer learning technique. In the conducted research the pretrained model of AlexNet was used. The net underwent slight modification of the structure and then the...
Few aspects of shunting effect have been studied so far. Shunting effect in resistance spot welding (RSW) occurs when the electrical current passes through the previous spot welds. Value of this current depends mostly on distance, number, and size of previous spot welds. This will cause some dimensional and metallurgical changes in welding nugget as well as heat affected zone (HAZ). In this study,...
