The Quality Information Framework (QIF) is a unified XML framework standard for computer-aided quality QIF systems, available free to all implementers.
QIF enables the capture, use, and re-use of metrology-related information throughout the Product Lifecycle Management (PLM) and Product Data Management (PDM) domains.
In August 2020, the DMSC announced the QIF 3.0 metrology standard was harvested, approved, and published by ISO as the new ISO Standard ISO 23952:2020; click to read more on this important status change.
The ASAM OpenDRIVE format provides a common base for describing road networks with extensible markup language (XML) syntax, using the file extension xodr. The data that is stored in an ASAM OpenDRIVE file describes the geometry of roads, lanes and objects, such as roadmarks on the road, as well as features along the roads, like signals. The road networks that are described in the ASAM OpenDRIVE file can either be synthetic or based on real data.
The main purpose of ASAM OpenDRIVE is to provide a road network description that can be fed into simulations to develop and validate ADAS and AD features. With the help of ASAM OpenDRIVE, these road network descriptions can be exchanged between different simulators. Providing a standardized format for road descriptions also enables the industry to reduce the cost of creating and converting these files for their development and testing purposes. Road data may be manually created from road network editors, conversion of map data, or originate from converted scans of real-world roads.
Similitude is a concept applicable to the testing of engineering models. A model is said to have similitude with the real application if the two share geometric similarity, kinematic similarity and dynamic similarity. Similarity and similitude are interchangeable in this context.
The term dynamic similitude is often used as a catch-all because it implies that geometric and kinematic similitude have already been met.
Similitude's main application is in hydraulic and aerospace engineering to test fluid flow conditions with scaled models. It is also the primary theory behind many textbook formulas in fluid mechanics.
The concept of similitude is strongly tied to dimensional analysis.
