Abstract: Fluidic systems, modules, and associated methods are generally described. In some embodiments, a fluidic system comprises a module which is configured such that fluid may flow therethrough with a relatively uniform time-averaged linear flow rate (i.e., the time-averaged flow rate that is perpendicular to the transverse cross-sectional area) and/or time-averaged flux across the transverse cross-sectional area of the module. Advantageously, such modules may behave in a way such that the time-averaged linear flow rate and/or time-averaged flux exhibits minimal or no dependence on the transverse cross-sectional area thereof. This may allow for modules to be scaled-up in a relatively facile manner by merely increasing the transverse cross-sectional area, which may eliminate or substantially reduce the need for other components of the module to be redesigned upon scale-up. In some embodiments, modules may be scaled-up in a manner that requires no or minimal chemical process adjustments.

Abstract: The disclosed computer-implemented method may include identifying and notifying requestors that may be candidates for a particular autonomous vehicle in order to find those candidates that may be willing or able to relax their travel constraints to match the autonomous vehicle. A request flow may involve surfacing the potential option of matching to an autonomous vehicle before setting a specific destination. For example, the request flow may involve determining that an autonomous vehicle is sufficiently near an in-session potential requestor. Before the potential requestor enters a specific destination, the request flow may present the possibility of the potential requestor being matched with the autonomous vehicle. In some examples, the request flow may then provide available drop-off locations that are compatible with the autonomous vehicle for selection by the potential requestor. Various other methods, systems, and computer-readable media are also disclosed.

According to the disclosed embodiments, the transportation matching system identifies low engagement transportation providers by analyzing information associated with the transportation providers to generate engagement levels. Furthermore, the system identifies an optimal match between a low engagement transportation provider (regardless of whether the transportation provider is online or offline) and a scheduled transportation request by utilizing attributes associated with a scheduled transportation request and attributes associated with transportation providers to generate rankings for the transportation providers. Additionally, the system provides the scheduled transportation request exclusively to a selected transportation provider based on the generated rankings.
