The project "Keyword-Based Exploration of Library Resources" addresses the challenges associated with accessing and discovering academic resources efficiently. Traditional systems often suffer from limitations such as inadequate multilingual support, poor metadata utilization, restricted filtering capabilities, which hinder users locating relevant research materials effectively. This proposes an innovative solution leveraging Artificial Intelligence (AI) Natural Language Processing (NLP)...
We present recent work on design, fabrication, and characterization of thin-film, flexible superconducting stripline cables. Fabrication details, dc, microwave performance (up to 14 GHz) cables with Al/Nb/Al conductors polyimide (PI) dielectric are discussed. Thin Al was used as a barrier layer between Nb protect the superconductivity during subsequent PI curing steps, which were performed at reduced temperature. The dc performance, including critical transition temperature current,...
