This paper proposes a novel method for channel estimation in a single-carrier MIMO system with frequencydomain equalization/detection. To this end, we construct novel short MIMO training sequences that have constant envelope in the time domain to preclude the peak-to-mean power problem encountered in many systems that utilize the frequency domain for data recovery. Simultaneously, the spectrum ...

How can we take householders from being disengaged passive energy consumers towards being highly motivated retrofitting energy saving masters? In this paper the ”Power law of engagement model for energy saving” is introduced, which breaks down the process of engaging householders into 8 defined stages. The model is based on the householder’s level of engagement and commitment, but applies Fogg’...

Finding influential spreaders of information and disease in networks is an important theoretical problem, and one of considerable recent interest. It has been almost exclusively formulated as a node-ranking problem— methods for identifying influential spreaders rank nodes according to how influential they are. In this work, we show that the ranking approach does not necessarily work: the set of...

KN) name -(1940). We should like to express our gratitude to the CERN Track Chamber Division, and specially to Professor Ch. Peyrou, Dr. R. Armenteros, and Dr. D. E. Plane, for supplying the film and the beam. This work would not have been possible without the encouragement and advices of Dr. R. Barloutaud, and one of us (J.G. ) would like to thank Professor A, Berthelot and Dr. A. Leveque for ...

In the context of two-path convexity, we study the rank, Helly number, Radon number, Caratheodory number, and hull number for multipartite tournaments. We show the maximum Caratheodory number of a multipartite tournament is 3. We then derive tight upper bounds for rank in both general multipartite tournaments and clone-free multipartite tournaments. We show that these same tight upper bounds ho...
