Abstract: In certain embodiments, transaction-subset-assignment of computer processing nodes may be facilitated to perform collateral allocation. In some embodiments, a query may be performed to obtain a set of transactions. Computer processing nodes may be selected from a set of available nodes for performing collateral allocations. Collateral allocation rules associated with a lender may be obtained, and each of the computer processing nodes may be caused to perform collateral allocations for one subset of the transaction set in accordance with the collateral allocation rules by assigning transactions of the transaction set respectively to the computer processing nodes such that the computer processing nodes collectively perform collateral allocations for the transaction set.

Abstract: Methods and system are described for optimizing data processing in cloud-based, machine learning environments. For example, through the use of a machine learning model utilizing a self organizing map and/or the use of specific processing nodes in a computer system to perform specific tasks the methods and system may more efficiently distribute tasks through a cloud computing environment and increase overall processing speeds despite increasing amounts of data. The methods and system described herein are particularly related to collateral allocation computer systems that automate the management of numerous collateral assets. For example, as the amount of collateral assets and the complexity of given transactions grow, typical allocation systems face frequent processing delays related to collateral allocations (e.g., allocations of collateral associated with Tri-Party Repos).

Abstract: A rotor assembly for an electric machine, e.g., of an electrified powertrain, includes a rotor having inner and outer diameter surfaces, and a rotor shaft connected to and surrounded by the rotor. The rotor has equally-spaced rotor magnetic poles each having a quadrature-axis (“q-axis”) and a pair of direct-axes (“d-axes”). At each of magnetic pole of the rotor, the rotor defines at least three arcuate notches, including a center notch bisected by the q-axis and a pair of additional arcuate notches symmetrically flanking the center notch. The rotor may include embedded permanent magnets, which may be arranged in a dual V-shaped configuration. Each additional notch may be positioned within a sweep of a top-layer opening angle of the magnets. The center notch and/or the pair of additional notches may define tangentially-continuous fillets which smoothly transition the notch into the outer diameter surface.
