The solid (or nonvolatile) particle number (SPN) emissions of light-duty and heavy-duty vehicles and engines are regulated in the European Union.The measurements are conducted from the tailpipe during on-road tests, but from the dilution tunnel in the laboratory under controlled conditions.Recently, dedicated laboratory studies for the evaluation o
Arboviruses can emerge rapidly and cause explosive epidemics of severe disease.Some of the most epidemiologically important arboviruses, including dengue virus (DENV), Zika virus (ZIKV), Chikungunya (CHIKV) and yellow fever virus (YFV), are transmitted by Aedes mosquitoes, most notably Aedes aegypti and Aedes albopictus.After a mosquito blood feeds
We investigate the decidability of the emptiness problem for three classes of distributed automata.These devices operate on finite directed graphs, acting as networks of identical finite-state machines that communicate in an infinite MIXED BERRY sequence of synchronous rounds.The problem is shown to be decidable in LogSpace for a class of forgetful
Recent research suggests that in some West German regions, single-family housing (SFH) neighbourhoods are prone to decay due to changed socio-economic and demographic trends.The question of whether similar demographic trends and implications for the SFH stock can be described for other West European countries such as Belgium, France, Netherlands an
