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 ...

A newly-discovered malicious package with layers of obfuscation is disguised as a utility library, with malware essentially hiding in plain sight in embedded QR codes. QR codes are ubiquitous these ...

Scammers are increasingly exploiting QR codes to trick people into revealing financial information or installing malicious software on their devices. The FBI has recently issued a warning about a ...

One of the lasting impacts of the COVID-19 pandemic is the popularity of QR codes. They’re everywhere, from your table at a restaurant and the register at your favorite coffee shop to random stickers ...

Sharat Potharaju is cofounder and CEO of Uniqode, whose vision is to enable digital connection with every physical object and place. QR codes drive 37% click-through rates, while email campaigns ...

QR-decomposition based QR-algorithm for eigenvalues evaluation of symmetric matrix with real values with OpenMP directives for parallelization of computations for multi-core systems ...

In this project it is used a Machine Learning model based on a method called Extreme Learning, with the employment of L2-regularization. In particular, a comparison was carried out between: (A1) which ...

Abstract: This paper deals with the pilot assisted time-varying channel estimation in orthogonal frequency division multiplexing (OFDM) systems. Since the pilot sub-carrier correlations are rank ...
