Number of connected IoT devices to grow 13% by end of 2024.According to IoT Analytics’ 171-pageState of IoT Summer 2024report, there were 16.6 billion connected IoT devices by the end of 2023 (a growth of 15% over 2022). IoT Analytics expects this to grow 13% to 18.8 billion by the...
Our main results concern complete intersections of three real quadrics. Weprove that the maximal number $B^0_2(N)$ of connected components that a regularcomplete intersection of three real quadrics in $\Bbb{P}^N$ can have differs atmost by one from the maximal number of ovals of the su...
