Time-Domain Precoding for LTE-over-Copper Systems

Crosstalk cancellation is a crucial issue for traditional digital subscriber line systems. For LTE-over-copper systems, however, the need for crosstalk cancellation varies depending on the analog fronthauling architecture and its parameters. A crosstalk handler that is decoupled as much as possible from the rest of the system architecture is thus preferred. Therefore, we propose a time-domain prec

Machinability of CuZn21Si3P brass

New brass alloys containing less or even no lead are being developed, decreasing the environmental impact of the material. One example of an alternative brass is CuZn21Si3P, which contains less than 0.09 wt-% Pb. The research presented in this article evaluates the machinability of CuZn21Si3P as compared to more common, lead-containing free-machining brasses. The results show a marked decrease in

Diagnoser i vår tid: Fastlåsning och blivande, totalitet och oändlighet

"I sin debattartikel Diagnoser i vår tid: Fastlåsning och blivande, totalitet och oändlighet debatterar Mattias Nilsson Sjöberg diagnoser i vår tid utifrån exemplet med ADHD. Utgångspunkt för diskussionen tas i posthumanismen och dess möjligheter att medverka till uppluckring av kategorier. För att undgå diagnosens tendenser till totalisering och fastlåsande är det viktigt att forma en djupare för
