  • Publication number: 20240393119
    Abstract: The disclosed computer-implemented method may include (i) receiving, by a dynamic transportation matching system, a request for transportation between initial waypoints, (ii) calculating, by the dynamic transportation matching system, a value metric for an initial driving route between the initial waypoints (iii) calculating a value metric for a walk-enabled driving route that comprises at least one alternate waypoint that is within a predetermined walking range of one of the initial waypoints, and (iv) improving, by the dynamic transportation matching system, a value of fulfilling the request for transportation by determining that a difference between the value metric of the walk-enabled driving route and the value metric of the initial driving route satisfies a walking-value threshold and selecting, based on the determination that the difference satisfies the walking-value threshold, the walk-enabled driving route for fulfilling the request for transportation.

  • Publication number: 20210404824
    Abstract: The disclosed computer-implemented method may include (i) receiving, from a transportation requestor device, a request for transportation that comprises a transportation stop at a location next to a street, (ii) matching, by a dynamic transportation matching system, the transportation requestor device with a transportation provider, and (iii) improving, by the dynamic transportation matching system, a value of fulfilling the request by (a) determining that a near side of the street is closer to the location of the transportation stop than a far side of the street, (b) mapping, based on the determination that the near side of the street is closer to the location of the transportation stop, a driving route that traverses the street, and (c) directing the transportation provider to fulfill the request for transportation by traversing the driving route. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 10633501
    Abstract: This disclosure provides an investigation of the kinetic uptake properties of water in amorphous PEF and PET across the entire water activity interval at various temperatures, and also investigates the corresponding equilibrium uptake properties at the same conditions. Uptake data were measured using three independent and complementary methodologies, and excellent agreement was observed among all three methodologies. Accordingly, this disclosure provides for methods of plasticizing poly(ethylene furanoate) film by cold water sorption, and provides a plasticized poly(ethylene furanoate) (PEF) film made according to the disclosed methods. Methods for making thin films of PEF are also provided.

  • Patent number: H765
    Abstract: The temperature of heated exhaust gases from a gas turbine is increased to value sufficient to vaporize fog oil to form smoke. The turbine itself is unmodified and requires no bleed air control valve at the air inlet to the compressor to regulate exhaust gas temperature.
