Defining the C-ITS Reference Architecture
2018 IEEE International Conference on Software Architecture Companion (ICSA-C), 2018 Cooperative-Intelligent Transport Systems (CITS) aims to facilitate cooperative, connected and automated mobility. The C-ITS domain comprises widely spread systems like traffic management systems, traffic light controllers, and vehicle on-board units. Such complex and heterogeneous systems have independent uses but demand a strategy to facilitate their

On weighted norm inequalities for the Carleson and Walsh-Carleson operators [PDF]
, 2013 We prove $L^p(w)$ bounds for the Carleson operator ${\mathcal C}$, its lacunary version $\mathcal C_{lac}$, and its analogue for the Walsh series $\W$ in terms of the $A_q$ constants $[w]_{A_q}$ for $1\le q\le p$.
