Abstract: An apparatus, system, and method is provided for predicting 3D shape deformation in additive manufacturing. A convolution learning framework for shape deviation modeling provides joint learning for a wide class of 3D shapes including both spherical and polyhedral shapes. A 3D cookie-cutter function can effectively capture the unique pattern of the shape deformation for polyhedral shapes. Since 3D freeform shapes can be approximated as a combination of spherical and polyhedral patches, the extended convolution learning framework builds a foundation for modeling and predicting the quality of 3D freeform shapes. By changing the kernel function and considering new distance measures for points from different shapes, the spatial correlations among different shapes can be correctly incorporated. The predicted deformation may be used to offset the machine instructions to an additive manufacturing machine to ameliorate deformation.

Abstract: Embodiments presented herein include systems and methods for cooling a device, such as a computing system for an autonomous vehicle. In one or more embodiments, a linear drive actuator may be employed to circulate cooling fluid (or coolant) to the computing system. Unlike typical hydraulic or linear actuators, embodiments herein are capable of consistent directional circulation of the fluid while the actuator is moving in both forward and backward directions. Using a linear actuator not only uses fewer parts as compared to current cooling systems, but such embodiments have additional benefits. A linear actuator cooling system can use a smaller motor than traditional pump cooling systems, has more control relative to rate and pressure, produces less noise, produces fewer vibrations, and has a longer lifespan. Embodiments may also be configured to facilitate circulation of the coolant even in the event of a controller or motor actuator malfunction.

Abstract: Described are techniques for identifying primary and foreign keys to build a schema. A primary key of a query table of a data lakehouse, which may consist of multiple columns, is identified. The top n-similar columns of the tables of the data lakehouse are then identified to identify the joinable tables using the primary key as a query using column embeddings. A list of candidate joinable tables is then identified based on the identified top n-similar columns of tables of the data lakehouse. Joinable tables from the list of candidate joinable tables are selected that satisfy an inclusion dependency constraint. The foreign keys having full containment with the primary key of the query table are then identified from the selected joinable tables. Such identified primary and foreign keys are utilized to build/discover the schema, such as a relational schema, of the data lakehouse.
