On the possibility of extending the service life of winter roads using renewable energy sources

It is hard to overestimate the role of winter roads in the land logistics of the northern regions. In recent years, climate change has not only significantly reduced the service life of winter roads, but also made them less predictable. This forces transpo ...

Optimal Design Operation Strategies of a Hyperloop Transportation System

Denis Tudor

In the last decades, transportation demand growth has played a major role in the increase of global CO2 footprint. At the same time, a number of countries have scheduled measurable and substantial cutback of CO2 emissions by 2050. As the transportation sec ...

Magnetoelectric Ponderomotive Force

Jean-Philippe Ansermet, Sylvain Bréchet, Alexandre Roulet

The dynamics of a system consisting of a matter continuum with a weak linear magnetoelectric coupling interacting with electromagnetic fields is examined on a local scale in a non-relativistic limit. A consistent expression for the internal energy of the s ...

A new solution for increasing the efficiency of an electric scooter with supercapacitors through a novel, interleaved multi-channel DC/DC converter

Alfred Rufer, Philippe Barrade, Blaise Destraz

Scooters are a well-established transport system for short distances – particularly within cities. Currently, the majority of scooters are petrol powered. Their engines typically exhibit bad efficiencies and thus contribute to global warming by CO2 product ...
