Pervasive Reflective Sensing with Visible light and Beyond

Considering that the IoT is giving rise to new sensing infrastructures with stringent requirements, we are posed with new trade-offs. On one hand, there is a need to develop systems that have a low cost, complexity, and ecological footprint, while being privacy-aware. On the other hand, despite these constraints, there is a need to still...

Tacit Knowledge Elicitation for Shop-floor Workers with an Intelligent Assistant

Many industries face the challenge of capturing workers' knowledge to share it, particularly tacit knowledge. The operation of complex systems such as a manufacturing line is knowledge-intensive. Considering this knowledge's breadth and dynamic nature, existing knowledge-sharing solutions are inefficient and resource intensive. Conversational...

Numerical simulation on reflective cracking behavior of asphalt pavement

Cracks are one of the main problems that plague road workers. A correct understanding of the internal crack propagation mechanism of asphalt pavement will help road workers evaluate the road’s working status more comprehensively and make more reasonable decisions in design, construction, and maintenance work. This paper established a three...

PassiveVLP: Leveraging Smart Lights for Passive Positioning

Positioning based on visible light is gaining significant attention. But most existing studies rely on a key requirement: The object of interest needs to carry an optical receiver (camera or photodiode). We remove this requirement and investigate the possibility of achieving accurate positioning in a passive manner—that is, without requiring...

Spin-Orbit Interaction and Induced Superconductivity in a One-Dimensional Hole Gas

Low dimensional semiconducting structures with strong spin-orbit interaction (SOI) and induced superconductivity attracted great interest in the search for topological superconductors. Both the strong SOI and hard superconducting gap are directly related to the topological protection of the predicted Majorana bound states. Here we explore the...
