The interplay of mechanical grinding and aniline vapor fuming on the fluorescence of the pentiptycene‐anthracene‐pentiptycene π‐conjugated molecules PAP‐Cn, where n is 4, 8, 12, or 16 and refers to the number of carbon atom in the terminal alkyl chains, in solid films are reported. The differences and similarities among the four homologs have led to a conclusion of the formation of an emissive triplex...
Pedestrian detection is an important topic in many applications, such as intelligent transportation systems (ITSs) or surveillance. For the purpose of applications used around the clock, the work for detecting pedestrian based on thermal sensors has attracted significant attention. To achieve this, this paper proposes a LBP (local binary pattern) encoded multi-level classifier for detecting pedestrians...
Student's reading attention is highly related to their reading ability and learning performance. Traditionally, it is a difficult procedure that when teachers want to observe the reading attention state of each students. In recent years, sensing technology-based applications and learning methods emerge in the increasingly mature environment. Most studies have shown the effectiveness of sensor-assisted...
Falling is the most frequent accident for the elderly in daily life. Falls can cause seriously injuries and even death. Although many fall detection methods have been developed to detect falls in real-time, most are inaccurate and inconvenient to use. Previous studies failed to correctly identify the relationship between normal activities and falls. Another problem is that many proposed methods considered...
The 3D tele-immersion technique has brought a revolutionary change to human interaction-physically apart users can interact naturally with each other through body gesture in a shared 3D virtual environment. The scheme of cloud-or web-based applications on the other hand facilitates users without the need to equip with additional software or hardware. To realize "web-based" 3D immersion techniques,...
We present a novel electrical impedance sensor for measuring the resealing time of porated mammalian plasma membranes. Openings were generated by high speed cavitation bubbles using laser pulsing of metallic microdisks on transparent ITO electrodes. Real-time impedance measurements show that membrane resealing time and impedance recovery takes 1 to 2 minutes after laser pulsing. Our method can also...
