This paper aims to investigate the effectiveness of some mid-block bicycle crossing elements by analyzing drivers’ behavior, when approaching crossings in a real road experiments with 18 participants. The eye-tracking instrument has been used monitor driver’s visual behavior during test an instrumented vehicle GPS (global positioning system) and inertial measurement unit (IMU). In particular, g...

This paper presents an approach for automated video indexing and video search in large lecture video archives. First of all, we apply video segmentation and key-frame detection to offer a visual guideline for the video content navigation. We further extract textual metadata by applying video Optical Character Recognition (OCR) on detected keyframes and by performing Automatic Speech Recognition...

An experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. The first specimen was a reinforced concrete frame with solid-brick infill. The second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. The last specimen was a reinforced concrete frame without any infill. These three specimens were tested by pseudostatic method. Di...
