Finally, the method for combining solution principles and the method for evaluating the created concept variants will be explained.
Then, the manner in which conceptual design follows a process of problem abstraction, establishing function structures, searching for solution principles, combining solution principles into concept variants, selection and confirmation of appropriate combinations, and the evaluation of the created concept variants, will be illustrated.
Research is based on assumption that "transformity" of product's working principles is also ecological quality criteria that might be used by designers for evaluating product's concept variants in early design stages of product development process.
The paper concerns possible concept variants of a partially reusable Heavy-Lift Launch Vehicle derived from the advanced basic launcher Ariane-20100) by means of substitution of the EAP Solid Rocket Boosters for a Reusable Starting Stage consisting two Liquid-propellant Reusable Fly-Back Boosters called "Bargouzin".
Due to rapid advances in biomedicine, dictionary-based methods cannot support the recognition of new concept variants appearing in text.
Inspired by weak label learning and semi-supervised learning, it comes up with a third solution for concept variant problem in game props recommendation task, i.e., Co-MIML with co-training techniques.
In five cases concepts or variants were not specified properly.
The remaining false positives were due to missing concepts or variants so that existing but wrong concepts were extracted.
Machine learning methods, on the other hand, can recognise new concepts and variants, based on comparison of their textual and contextual features with known concept instances.
Among the elastic notch stress concepts, the variant with the reference notch radius, ρr = 1 mm, recently verified also for welded joints in aluminium alloys with plate thicknesses t ⩾ 5 mm and the variant with a small-size reference notch radius, ρr = 0.05 mm, applicable to welded joints in thin-sheet materials, are outlined.
