Astronomische Nachrichten, Volume 347, Issue 1, January 2026.ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

The Study of Building Information Model Server Focusing on IFC‐to‐RDB Conversion
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Different Industry Foundation Classes (IFC)‐to‐relational mapping strategies may result in substantially different database structures and performance characteristics. However, systematic comparisons remain limited because existing studies often employ different implementation methods and evaluation conditions.

Development of Functionality-Based Conformance Classes for ISO 10303 – Conformance Classes for Tolerancing Functionality [PDF]
Computer-Aided Design and Applications, 2009 ISO 10303 which is STandard for the Exchange of Product model data (STEP) contains a large amount of extremely detailed information. There are no clear and easy instructions for implementing STEP, and the only way to check whether a developed software product actually satisfies STEP requirements is to test it using Conformance Classes (CCs), which are ...
