Conventional methods used for reconstructing road traffic scenes often rely on fixed sensors and cameras entrenched within road infrastructure. However, these approaches grapple with substantial limitations in terms of scope, cost-efficiency, and safeguarding individual privacy. The need to fortify road safety, strengthen urban planning initiatives,...

Background Real-time immediate feedback is known to enhance learning by providing better engagement with learners, as seen in a classroom environment with teachers. Applications with automated feedback are designed to mimic the prompt feedback provided by teachers in a classroom. Advances in artificial intelligence (AI) technology have enabled this...

­Background Cyber-physical systems (CPSs) involve complex interacting components including the physical environment and human participants. As such, faulty operation of any CPS sub-component presents serious safety risks. Faulty CPS operation can occur due to several reasons including differences in architectures and sub-optimal implementation....

The common approach for transportation of hydrogen - the least dense of all gasses - is to substantially densify it so it can economically suit existing transportation modes. Densification is achieved by compression (up to 700 bar), by liquefaction (cooling below -253 °C), or by chemical conversion. Conventional hydrogen transportation methods often...
