Abstract: Electric machines and related methods are generally described. In some embodiments, an electric machine may be integrated with a thermal management system for high specific power output performance. The construction and operational parameters of the systems may be 5 precisely designed to achieve high specific power outputs between 10 kW/kg and 25 KW/kg. The thermal management system may include a heat exchanger integrated directly into the electric machine for enhanced thermal transport out of the system. A fluid (e.g., air) may flow through various flow paths throughout the system to increase cooling of the system.

Abstract: A system for vehicle transportation operates to receive decision data indicating decisions for transportation of cargo from one or more originating locations to one or more destination locations by one or more vehicles, wherein the one or more vehicles are configured to transport between the originating locations and the one or more destination locations by operating one or more tractive components of the one or more vehicles. The system operate to generate a plurality of scenarios, by generating a baseline scenario including a plurality of decisions indicated by the decision data, performing a plurality of modifications to the baseline scenario by making one or more adjustments to the plurality of decisions of the baseline scenario, and saving the modifications of the baseline scenario as the plurality of scenarios. The system operate to determine emissions production resulting from the plurality of scenarios and generate one or more updates to the transportation.

Abstract: A data management system that operates to receive high level data of categories for a corpus of entities, the high level data indicating characteristics of the corpus of entities that indicate emissions production of each entity of the corpus of entities. The data management system operates to select one or more modeling assumptions for the categories, the one or more modeling assumptions modeling low level consumption data based on the high level data and generate emissions indicators for each of the categories for each entity of the corpus of entities for a plurality of points in time based on the high level data and the one or more modeling assumptions. The data management system operates to sort the emissions indicators into a plurality of buckets based on the categories and generate data causing a computing device to display the emissions indicators sorted into the plurality of buckets.

Abstract: Disclosed herein are methods and systems for modeling and controlling the disparate components (e.g. generators, storage, propulsors, and power electronics) that comprise an aircraft turbo-electric distributed power (TeDP) system. The resulting control system is hierarchical and interactive. Layer one is the physical electric power system. Layer three is an optimization system that determines set points for system operation. Layer two, in between layer one and layer three, includes nonlinear, fast, dynamic power-electronic controllers that hold the operation of the power system to the desired set points. Communication between these layers ensures feasibility and stability of the controlled operation. Simulations demonstrate that the resulting control system ensures stability and maximum efficiency.

Abstract: A method for forming a digestible pet chew includes combining ingredients including a leavening agent and an acid to form a mixture having about 16 to 32% moisture, adding the mixture to a barrel of an injection molding machine, and plasticizing the mixture with heat and pressure to form a plasticized material. The plasticized material is then injected into a chilled mold and cooled in the mold for a time sufficient to form a skin surrounding a center portion. The mold is then released to allow the center portion to expand to form a pet chew having an outer skin and an expanded center.

Abstract: A cold-set, injection-molded digestible pet chew includes an outer skin layer having a tough, chewy texture and an expanded center being surrounded by the outer skin layer. The outer skin layer and the expanded center being are formed by injecting a plasticized mixture into a chilled mold and cooling in the mold for about 10-60 seconds followed by releasing the mold to allow the center to expand to form a digestible pet chew. The plasticized mixture includes protein, starch, 0.1-2.5% encapsulated leavening agent, acid, and 5-15% of a humectant. The encapsulated leavening agent reacts with the acid to form the expanded center within the outer skin layer. Further, the pet chew has a water activity of 0.60 or below such that the expanded center remains expanded.
