Density of the reachable states can help understand risk safety-critical systems, especially in situations when worst-case reachability is too conservative. Recent work provides a data-driven approach to compute density distribution autonomous systems’ forward online. In this paper, we study use such combination with model predictive control for verifiable safe path planning under uncertainties...

ResearcherS used two behavioral prompts to compare increases in safety belt use: a Click It or Ticket prompt or a Flash-for-Life prompt. Participants were 1,822 unbuckled drivers exiting two student parking lots of a large university. Research assistants identified unbuckled drivers, flashed one of the two prompts, and recorded whether drivers buckled after the prompt and the drivers' facial ex...

Abstract In order to improve the safety of digital subtraction angiography (DSA) equipment in treatment cardiovascular diseases, a hybrid collision detection algorithm based on separation distance is proposed by combining oriented bounding box (OBB) with GJK algorithm. Firstly, according structure DSA equipment, real-time position simulated robot operating system (ROS); Then, OBB used envelope ...

introduction: since hospitals give their services to a huge number of people most of whom are sick and disabled and also because they have many expensive and modern equipment and facilities, any negligence regarding the standards of safety management leads to severe damages including financial ones. this may even result in irrecoverable consequences such as their clients’ death. so, this invest...

The predominant risk culture within the UK surrounding protecting children from online predators has a strong influence on the type of awareness raising activities being promoted for children. As reflected in the terminology in the field, e-safety has moved through Internet Safety to be commonly referred to in child protection circles as online safeguarding. Whether this change in terminology b...
