Decoupled control scheme of grid-connected split-source inverters

2017

Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…

Wyzwalanie dziecięcej aktywności matematycznej w trakcie rozwiązywania zadań

2018

Aktywność ucznia ma ogromne znaczenie w kształtowaniu i rozwijaniu abstrakcyjnych pojęć matematycznych. Jednak aktywność ta nie powinna ograniczać się jedynie do aktywności zewnętrznej, często jedynie pozornej, ale przede wszystkim powinna być to aktywność umysłowa ucznia. Zachowania i postawy specyficzne dla aktywności matematycznej można bowiem rozwijać u ucznia jedynie w toku jego aktywności poznawczej (intelektualnej). W opracowaniu podjęto próbę ukazania możliwości stymulowania i rozwijania oraz przejawy aktywności matematycznej uczniów w wieku wczesnoszkolnym w trakcie rozwiązywania zadań.

Beam-induced and cosmic-ray backgrounds observed in the ATLAS detector during the LHC 2012 proton-proton running period

2016

This paper discusses various observations on beam-induced and cosmic-ray backgrounds in the ATLAS detector during the LHC 2012 proton-proton run. Building on published results based on 2011 data, the correlations between background and residual pressure of the beam vacuum are revisited. Ghost charge evolution over 2012 and its role for backgrounds are evaluated. New methods to monitor ghost charge with beam-gas rates are presented and observations of LHC abort gap population by ghost charge are discussed in detail. Fake jets from colliding bunches and from ghost charge are analysed with improved methods, showing that ghost charge in individual radio-frequency buckets of the LHC can be resol…
