Modern wireless communication systems employ large bandwidth digital modulated signals with very high peak-to-average power ratio (PAPR) to enhance spectral efficiency and maximize the data rate. However, high PAPR digital modulations schemes are strongly detrimental for the radiofrequency (RF) amplifier that must operate most of the time several dB in back-off with respect to the nominal power and, therefore, with very low efficiency. A common technique to improve the RF high power amplifier ...

The question of the worlwide climate modification, due to the human emissions (i.e. greehnouse gas) is alwais more stringent: Europe consumes more petroleum for transportation than for any other energy use; transportation is responsible for about half of the smog forming pollutants in our cities, for up to 90% of the carbon monoxide, and for more than half of the toxic air pollutants. The need to accelerate the development of the technologies able to reduce the effect of the human activity ...

Computer science today is driven by two main trends: the use of computing resources on demand (outsourced computing) and the need of processing a huge amount of data coming from different sources (data-centric computing). The effects of these two trends will lead the future computing platforms towards hybrid systems composed of distributed specialized subsystems with specific and complementary features that operate synergistically. These systems will interact with the users by means of multiple ...

The continual progress of physics provides an insight ever deeper of the Universe, and also to have new technologies, but at the same time place us in front to new and new demands. One of the open questions in physics is to reconcile the two most successful theories of physics, Einstein's general relativity and quantum physics, which work perfectly, but in completely different fields. General relativity explains gravity and the universe at large scale, astronomical and cosmological, and at the ...

The main aim of industrial prototyping is to create a tangible representation of an arbitrary digital geometry. Industrial fabrication is generally tuned for a specific object and the initial setup is usually a time consuming operation. The more complex the shape of the object, the more complex is the manufacturing process. Obviously, implementing a similar process to create a single (or a few) prototype(s) is not efficient. To deal with these specific industrial needs 3D printing devices have ...
