Just how small can a QR code be? Small enough that it can only be recognized with an electron microscope. A research team at TU Wien, working together with the data storage technology company Cerabyte ...
Abstract: In this paper, we propose a new approach to justify a roundoff error impact on the accuracy of the linear least squares (LS) solution using QR decomposition ...
We present optimal parallel QR factorization algorithms with reduced communication overhead. QR factorization is widely applied to solve various problems in numerical linear algebra. Our focus is on ...
The Federal Bureau of Investigation has issued a warning about a growing cyber threat that turns everyday QR codes into spying tools. According to the bureau, a North Korean government-sponsored ...
