Abstract: Transmitting digital definitions of skills at a computing system to allow the digital definitions skills to be interoperable with other computing systems. The method includes identifying a skill name for a skill. The method further includes contextualizing the skill name for a specific system or use case by creating and storing metadata associated with the skill name. The method further includes publishing the contextualized skill at a predetermined network location, in a standardized digital format allowing for interoperability with other computing systems, wherein publishing comprises providing an active network link to the contextualized skill.

Abstract: Pressureless sintering of silicon carbide with fracture toughness in excess of about 4 MPa-m1/2 as measured by the single-edge precracked beam (SEPB) technique while maintaining a density greater than 3.1 g/cc for compositions with SiC greater than about 94 wt. % is made possible through the use of metallic Al to promote sintering and grain growth. Boron and carbon may be used as traditional sintering aids, with nitrogen to suppress grain growth, and additions of yttrium and/or lanthanide elements to promote intergranular fracture.
