This article assesses the main innovations in the newly adopted Directive 2015/1513 on renewable energy and biofuels in the EU transport sector. It analyses the strengths and weaknesses of this legal framework and reflects on possible future elaborations of the EU approach to renewable energy and sustainable biofuels in the transport sector. These developments must be in balance with the productio

The elemental composition of the St. Louis aerosol has been investigated at rooftop sites in south and central locations in the city as part of the August, 1973 field season of the Regional Air Pollution Study of the U.S. Environmental Protection Agency. Sampling by 5-stage cascade impactor with backup filter permits analysis by proton-induced x-ray emission (PIXE) of size fractions of aerodynamic

The present article reports results from tests performed to investigate different designs of a scrolling function used to make it possible for the user to navigate a virtual environment larger than the limited workspace of the haptic device. A preliminary

Resilient devices are commonly used in lightweight structures to decrease sound transmission in a broad frequency band. Applications of such devices may be found in e.g. resilient mounted ceilings in aeroplanes, ships and buildings. A measurement method to characterise the frequency dependency of the transfer stiffness and the input stiffness of the resilient device is presented. The mechanical ch

A new stream cipher, Grain-128, is proposed. The design is very small in hardware and it targets environments with very limited resources in gate count, power consumption, and chip area. Grain-128 supports key size of 128 bits and IV size of 96 bits. The design is very simple and based on two shift registers, one linear and one nonlinear, and an output function
