Satellite drag coefficient modeling for thermosphere science and mission operations

Satellite drag modeling remains the largest source of uncertainty affecting space operations in low Earth orbit. The uncertainty stems from inaccurate models for mass density and drag coefficient. Drag coefficient modeling also impacts scientific knowledge on the physics and dynamics of the upper atmosphere through the estimation of high...

Vulnerable road users and the coming wave of automated vehicles: Expert perspectives

Automated driving research over the past decades has mostly focused on highway environments. Recent technological developments have drawn researchers and manufacturers to look ahead at introducing automated driving in cities. The current position paper examines this challenge from the viewpoint of scientific experts. Sixteen Human Factors...

The 4D LINT model of function allocation: Spatial-temporal arrangement and levels of automation

Human factors researchers are well familiar with Sheridan and Verplank’s (1978) ‘levels of automation’. Although this automation dimension has proved useful, the last decade has seen a vast increase of automation in different forms, especially in transportation domains. To capture these and future developments, we propose an extended automation...

REE recovery from end-of-life NdFeB permanent magnet scrap: A critical review

NdFeB permanent magnets have different life cycles, depending on the applications: from as short as 2–3 years in consumer electronics to 20–30 years in wind turbines. The size of the magnets ranges from less than 1 g in small consumer electronics to about 1 kg in electric vehicles (EVs) and hybrid and electric vehicles (HEVs), and can be as...

Fire safety regulations for housing in Europe compared

There is still broad variety of systems of technical requirements for buildings in the various European countries, despite the existence of the Construction Products Directive of the European Union and the development of Euro Codes. The goals and topics are quite similar, but detailed study reveals considerable variety of functional requirements...
