Optimized Coverage Planning for UV Surface Disinfection [PDF]

arXiv, 2021
UV radiation has been used as a disinfection strategy to deactivate a wide range of pathogens, but existing irradiation strategies do not ensure sufficient exposure of all environmental surfaces and/or require long disinfection times. We present a near-optimal coverage planner for mobile UV disinfection robots. The formulation optimizes the irradiation

Radiation-Hard Optical Link for SLHC [PDF]

Nucl.Instrum.Meth.A596:88-92,2008, 2008
We study the feasibility of fabricating an optical link for the SLHC ATLAS silicon tracker based on the current pixel optical link architecture. The electrical signals between the current pixel modules and the optical modules are transmitted via micro-twisted cables.
