Abstract: Cooperative stochastic positioning in a mobile environment is provided. Position announcements transmitted wirelessly from objects in the immediate area are received at an object of interest or primary object. The position announcements provide the current position data of the respective object in relation to a common coordinate system. The received position announcements are discretizing to obtain a plurality of data groupings based upon a clustering criteria applied to the received position data. Clustering of the data groupings is performed to determine which clusters dataset from the data groupings provide sufficient and consistent position accuracy to determine a relative position of the primary object. A stochastic automata model is then applied to selected cluster dataset to evaluate relative cluster weights in order to determine the relative position of the object of interest. The accuracy of a current position of the object of interest can then be updated based upon determined relative position.

Abstract: A method for recovery of impurities and/or degradation products and/or heat-stable salts from amine-based solvents used for capture of CO2 from gas streams. The method comprises recovering CO2 from a CO2-enriched amine-based solvent thereby producing a lean amine-based solvent, contacting and mixing together the lean amine-based solvent with a reaction composition comprising a phase-change catalyst and a diluent, thereby producing a first organic phase comprising the impurities and/or degradation products and/or heat-stable salts and a first aqueous phase comprising the lean amine-based solvent, separating the first organic phase and the first aqueous phase; and separately recovering the first organic phase and the first aqueous phase. The organic phase can be regenerated by intermixing with a NaOH solution to form an organic phase comprising therein the reaction composition and and an aqueous phase comprising the NaOH solution with the impurities and/or degradation products and/or heat-stable salts.

Abstract: The present disclosure is directed at an adaptable vehicle that includes a pair of primary rollers for rolling along a surface on which the vehicle is travelling. At least one of the rollers is rotatably powered. The adaptable vehicle also includes two sets of linking arms, one of which is coupled to one of the rollers and the other of which is coupled to the other of the rollers such that moving the sets of linking arms can shift the axes of rotation of the rollers without impeding rotation of the rollers. The sets of linking arms are connected to and rotatable about an actuatable hub. Actuation of the hub causes at least one set of the linking arms to rotate about the hub and shifts the axis of rotation of at least one of the rollers to allow the vehicle to adapt to its surroundings.
