A method includes determining an operational parameter of a first vehicle traveling with a plurality of vehicles in a transportation network and / or a route in the transportation network, identifying a failure condition of the first vehicle and / or the route based on the operational parameter, obtaining plural different sets of remedial actions that dictate operations to be taken based on the operational parameter, simulating travel of the plurality of vehicles in the transportation network based on implementation of the different sets of remedial actions, determining potential consequences on travel of the plurality of vehicles in the transportation network when the different sets of remedial actions are implemented in the travel that is simulated, and based on the potential consequences, receiving a selection of at least one of the different sets of remedial actions to be implemented in actual travel of the plurality of vehicles in the transportation network.

A method and apparatus for upgrading a petroleum feedstock with supercritical water are provided. The method includes the steps of: (1) heating and pressurizing a petroleum feedstock; (2) heating and pressurizing a water feed to above the supercritical point of water; (3) combining the heated and pressurized petroleum feedstock and the heated and pressurized water feed to produce a combined feed; (4) supplying the combined feed to a hydrothermal reactor to produce a first product stream; (5) supplying the first product stream to a post-treatment process unit to produce a second product stream; and (6) separating the second product stream into a treated and upgraded petroleum stream and a water stream.

A method and apparatus for underwater pelletizing and subsequent drying of polyethylene terephthalate (PET) polymers and other high temperature crystallizing polymeric materials to crystallize the polymer pellets without subsequent heating. High velocity air or other inert gas is injected into the water and pellet slurry line to the dryer near the pelletizer exit. The slurry line has a substantially straight component, and air is preferably injected at the end of the straight component nearest the pelletizer exit and in a direction substantially coincident with the axis of the straight component. The air injection significantly increases the speed of the pellets into and out of the dryer such that the PET polymer pellets leave the dryer above at least 135° C., and preferably above 145° C., to self-initiate crystallization.

Process for the purification of toluenediisocyanate from a crude distillation feed comprising toluenediisocyanate, an organic solvent and less than 2% by weight phosgene by separating the crude distillation feed in a dividing-wall distillation column into at least four product fractions P1-P4. P1 is a phosgene enriched low-boiler product, P2 is a solvent-enriched product, P3 is a high boiler enriched bottoms and P4 is a toluenediisocyanate product stream.

The present invention relates to a system and methodology for extending and making more appropriate the interactive decisions made by automated services by taking into consideration estimates of the time required by users for the cognitive processing of problems, visualizations, and content based on several factors, including the competency and familiarity of the user with the output and nature of the sequences of output, the complexity of the output and overall tasks being considered, and the context of the user. The methods allow automated applications to control the rate at which the applications interact with users. Portions of automated services are controlled in view of limited human processor capabilities in design / operation of such services, and / or visualizations / output from the services (e.g., amount of dwell time provided / considered before a next automated sequence is displayed / invoked). Models can be formulated and utilized in conjunction with automated services such as automatically determining and pausing a period of time before a next sequence in a service is enabled or disabled. The models can also be employed to determine multiple dwells for comprehension, as a function of complexity of graphical / conceptual relationships, at different phases of an animation.
