An attention-guided algorithm for improving the performance of acoustic simulations

When performing acoustic simulations with the purpose of auralization, there is a trade-off between accuracyand speed. In real-time simulations of virtual reality, finding the balance of this trade-off is paramount to achiev-ing the desired result. If successful, the simulation speed is sufficient to provide a seamless acoustic experienceas the agent moves around the space, while still being accur

Association with Lepton Pairs Produced via the Photon Fusion Mechanism at ATLAS

The observation of forward proton scattering in association with lepton pairs (e+e−+p or μ+μ−+p) produced via photon fusion is presented. The scattered proton is detected by the ATLAS Forward Proton spectrometer, while the leptons are reconstructed by the central ATLAS detector. Proton-proton collision data recorded in 2017 at a center-of-mass energy of √s=13 TeV are analyzed, corresponding to an

Wavelength frame multiplication for reflectometry at long-pulse neutron sources

The European Spallation Source (ESS), which is under construction in Lund (Sweden), will be the next leading neutron facility with an unprecedented brilliance and novel long-pulse time structure. A long-pulse source not only provides a high time-average flux but also opens the possibility to tune the resolution by using pulse shaping choppers. Thus, an instrument can readily be operated in either

Swedish School Reforms and Teacher Professionalism

The education policy of the last few decades has significantly changed the Swedish school system. Municipalization and deregulation reforms were implemented in parallel with an internationally prescribed professionalization of teachers. This seemingly contradictory combination has reshaped not only teachers’ attitudes and actions but also those of principals and students as managers and consumers.
