Abstract: Systems and methods for optimizing database routing in accordance with embodiments of the invention are illustrated. One embodiment includes a tiered database. The tiered database includes a data warehouse used to store obtained data. The tiered database includes a relational layer that stores a copy of a subset of the obtained data within a certain period of recency. The tiered database includes a query planner. The query planner is configured to receive a new query and determine a query plan to respond to the query. The query planner is configured to compute, from a set of database metrics and the preliminary query plan, a storage access cost. The query planner is configured to route the query based on the storage access cost, wherein the query is routed: to the data warehouse when the storage access cost exceeds a predetermined threshold; and to the relational layer otherwise.

Abstract: Systems for a voltage balanced multi-set hairpin windings for electric motors are provided. The systems comprise a stator assembly of an electric motor system, a plurality of radial slots positioned around an inner cylindrical surface, and a winding scheme for the stator assembly including alternating positioning of a hairpin wire having a seven slot span and another hairpin wire having a five slot span in four sub-circuits.

Abstract: The present disclosure is concerned with a stator for an electric machine comprising a plurality of stacked laminations each including inwardly facing slots defining inwardly facing teeth configured to receive prewound coils thereonto. Each slot including a generally triangular projection configured and sized as to be in proximity of the prewound coils.

Abstract: An electric machine provided with a stator structure including internal and external layers of interleaved pre-wound coils made of rectangular wire coated with enamel insulation varnish is described herein. The two layers of pre-wound coils allow the use of slightly different size of pre-wound coils, which facilitates their insertion into the stator slots.

Abstract: The technology disclosed relates to creating and frequently updating multiple online analytic processing (OLAP) analytic databases from an online transaction processing (OLTP) transaction updatable system that includes transaction commit, rollback, and field level security capabilities. It also relates to transparently decoupling extraction from rebuilding of frequently updated OLAP analytic databases from the OLTP transaction updatable system.
