Recent in situ observations during Critical Ionization Velocity (CIV) experiments under the CRIT project produced puzzling results, apparently at odds with current ClV theories. It is shown that incorporation in the theory of lower hybrid wave (LHW) instabilities of strong turbulence and finite size effects results in reconciliation of the theory with the observations.

The paper brings to the fore need for state support by making investments in railway infrastructure, order maintain and ensure success of transport trucks introducing RO-LA rail traffic. Using this mode reduces cost maintaining road protects environment, fuel consumption, traffic congestionRO-LA is an alternative solution auto contributes streamlining goods people.

Guidelines and regulations for the siting of industrial wind turbines (IWT) close to human habitation are generally predicated on the need to protect the sleep of the residents. ssumptions that IWT noise can be regarded as similar to other forms of environmental noise (traffic, rail and aircraft) and is masked by ambient noise. There has been no independent verification that these assumptions a...

Due to the availability of precise satellite navigation systems, namely GPS and in the near future Galileo, which provide reference position, time and integrity information on a global and uniform basis, rail traffic is facing a revolution in terms of flexibility of operations. Autonomous satellite navigation receivers combined with a communication subsystem, so-called telematics systems, are u...
