Abstract: In various examples, systems and methods are disclosed for generating and/or analyzing candidate paths for a multi-body vehicle—e.g., a tractor trailer truck—based on obstacle avoidance considerations and using an uncertainty representation for the vehicle. The uncertainty representation may correspond to a trailer portion of the multi-body vehicle to account for the variations in rotation of the trailer with respect to the tractor. As such, the uncertainty representation may be indicative of a probability that the trailer of the vehicle occupies locations and/or points in world space. This probability—combined with the probability of locations of actors in the environment—may be used to generate candidate paths that satisfy various constraints—e.g., a minimum stochastic distance—between the vehicle and the actor.

Abstract: This invention provides method of treating a surface of exterior wood outside of buildings to inhibit the uptake of moisture into the wood by spraying on the surface of the wood an aqueous formulation consisting of one or more film forming non-chloride, long-chain polymers. The aqueous formulation forms a clear micro-film. Preferably, the long-chain polymer is polyethylene-vinyl acetate, polyurethane, or a combination thereof, wherein the clear micro-film contains no detectable volatile organic compounds. A clear colorant is added to the aqueous formulation to verify treatment. The clear colored micro-film maintains moisture content in the wood at 16 percent or less, allows for continued visual inspection of the surface of the wood for termite damage, does not rub off, get diluted with water, or become damaged by workers and pets who come into contact with the clear colored microfilm.
