Dynamic Characterization of a Railway Pantograph

I litteraturen finns det flera olika modeller för strömavtagare för järnvägar. Varje tillvägagångssätt syftar till att inkludera en specifik funktion, men har i sin tur begränsningar. Enkla modeller finns tillgängliga och de ger en bra bild av den dynamiska interaktionen mellan de olika delarna, men de tar inte hänsyn till komplexiteten hos varje ...

The aesthetic sublime of megaproject structures: A framework and a research agenda

European Management Review, EarlyView.
Abstract The physical structures of megaprojects—such as mega‐canals, metros, railway lines, bridges, tunnels, and iconic opera houses—hold a profound capacity to generate aesthetic experiences with enduring societal impact.

Rational Expectations Fools' Bubbles

International Economic Review, EarlyView.
ABSTRACT We develop a rational, Walrasian model of speculative bubbles inspired by the Kindleberger–Minsky view, which describes bubbles as wave‐like market processes. Touched off by an initial shock, price booms are initially self‐reinforcing but become self‐destructive later when prices surpass fundamental value.
