Automatic Joining of Electrical Components to Smart Textiles by Ultrasonic Soldering
Sensors, 2021 A suitable connection method to automatically produce E-textiles does not exist. Ultrasonic soldering could be a good solution for that since it works with flux-free solder, which avoids embrittlement of the textile integrated wires.

Joining Extractions of Regular Expressions [PDF]
, 2017 Regular expressions with capture variables, also known as "regex formulas," extract relations of spans (interval positions) from text. These relations can be further manipulated via Relational Algebra as studied in the context of document spanners, Fagin
