Platform competition processes: A future research outlook

Platform competition for market share can have broad ranging implications within or across industry sectors. It is subject to the complex and changing socioeconomic context in which it unfolds. Three trends provide evidence for this: (i) the number of relevant factors for platform market dominance is steadily increasing, (ii) industries...

Pin-pin resonance as a reference in determining ballasted railway track vibration behaviour

Pin-pin resonance is one of the most significant preferred vibration modes of beams, which are supported at equal distances, such as rails at sleepers in railway track structures do. Pin-pin resonance is a vibration that appears in one basic (first) mode and several higher modes, however the basic mode will have the highest amplitudes. In...
