a r t i c l e i n f o Using cross-national comparative analysis, this paper discusses the reasons why France has succeeded in partially privatizing its most recently constructed high speed line, while the U.S. has not reached this stage. The authors argue that France, with an interventionist government, diverged from the U.S. during the Great Depression by nationalizing its private railways and...

One of the most dynamical interplanetary phenomena of solar terrestrial physics is definitely the passage of solar wind streams near the Earth environment. In this work, we have identified the two types of high-speed solar wind streams using the spacecraft data during high amplitude days. The behaviour of high-speed solar wind streams during high amplitude anisotropic wave trains is investigate...

During the last decade Railways have become one of the most advanced and fast developing branches of transportation technology. The reason is very high speeds achievable by the most advanced modern trains (French TGV, German ICE, Italian Pendolino, Swedish X2000, Spanish AVE, Belgium Thalys, the Eurostar) and very low air pollution per passenger compared with road vehicles. Unfortunately, the i...

After the earlier technologies that offered satellite mobile services for civil and military applications, today’s specific antenna design, modulation techniques and most powerful new generation satellites also allow a good level of performance to be achieved onboard high speed modes of transport such as aircraft and trains. This paper reports the Eutelsat’s experience in the developing and dep...
