Abstract: Techniques are described for an interactive query service that enables users to query data stored at a federated collection of data sources. An interactive query service provides interfaces that enable users to configure the interactive query service to query any number of heterogeneous data sources pertinent to a user. In general, the configuration of a data source can include identification of: a data source type, access configurations related to accessing the data source, and in some cases metadata describing a structure of the data stored by the data source (for example, a data catalog describing schemas, tables, columns, partitions, datatypes, or other metadata associated with the stored data). Once configured, an interactive query service can receive and execute queries that involve data stored at any combination of a user's data sources, where the queries may be expressed using a standard query language such as the Structured Query Language (SQL).

Abstract: The system may include a rotatable stage configured to support a ceramic substrate and an energy emitter positioned adjacent to the ceramic substrate. In some cases, the energy emitter may be configured to transmit an energy beam toward one or more outer faces of the ceramic substrate so as to modify a surface roughness of the one or more outer faces. In some cases, the method may include identifying a target surface roughness based at least in part on a target friction coefficient, and identifying a target surface area of the ceramic substrate, transmitting an energy beam toward the surface of the ceramic substrate via an energy emitter positioned adjacent to the ceramic substrate, and heating the target surface area of the surface of the ceramic substrate until a surface roughness of the target surface area is within a predetermined range of the target surface roughness.

Abstract: An infant play mat with a flexible central mat portion having a fabric surface that forms a first infant play area including multiple flexible flaps. The infant play mat has a polygonal perimeter with multiple straight edges, with two of the edges defining a corner therebetween. Multiple flexible flaps extend from a respective one of the perimeter edges and define a fold line. Each flap has an upper flap surface exposed when the flap is extended, and hidden when the play mat is folded at the fold line to cover a region of the central mat portion. The central mat portion and lower surfaces of the flaps together form a second infant play area when the play mat is folded at all of the fold lines.

Abstract: A non-contact method of characterizing the isostatic strength of a ceramic member or article includes capturing a digital image of the ceramic article, and then forming a two-dimensional representation of the ceramic article and the web therein based on the captured digital image. The method also includes performing finite-element analysis on the two-dimensional representation of the ceramic article using a select amount of simulated isostatic pressure to determine a maximum stress value within the two-dimensional representation of the web. The method further includes using the maximum stress value to characterize the isostatic strength of the ceramic article.
