The Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter (SolO) provides a unique opportunity to systematically perform stereoscopic X-ray observations of solar flares with current and upcoming X-ray missions at Earth.These observations will produce the first reliable measurements of hard X-ray (HXR) directivity in decades, provi

There are many different mathematical models that can be used to describe relations between energy machines in the power-split hybrid drive system.Usually, they are created based on simulations or measurements in bench (laboratory) conditions.In that sense, however, these are the idealized conditions.It is not known how the internal combustion engi

Abstract Background Given that Swedish authorities have been widely viewed as having practiced an unusual approach to the COVID-19 pandemic and given that Sweden is notable for a low incidence of trauma, we wanted to learn how the pandemic may have affected the number of trauma admissions in Sweden.Methods We conducted a retrospective cohort study

Poly vinylidene chloride-vinyl chloride emulsions (PVDC) were added as a substitute for chlorinated paraffin (CP) in the preparation of ultra-low density fiberboards (ULDFs).The micromorphology and fire performance of ULDFs were investigated using a scanning electron microscope, limiting oxygen index instrument, and cone calorimeter.The results sho

Driver monitoring systems (DMS) are a key component of vehicular safety and essential for the transition from semi-autonomous to fully autonomous driving.Neuromorphic vision systems, based on event camera technology, provide advanced sensing in motion analysis tasks.In particular, the behaviours of drivers’ eyes have been studied for the det
