Renewable and Sustainable Energy Reviews
Exergy and entropy generation analysis of the open systems allows to obtain a measure of how far the open real systems deviate from equilibrium with their environment. A link between entropy generation maximum principle and the exergy analysis of engineering and natural systems is suggested in order to use the exergy and entropy approach to improve the renewable energy systems. © 2012 Elsevier Ltd.

This paper is devoted to an in-depth discussion of the Gaussian Noise (GN) model which describes non-linear propagation in uncompensated coherent transmission systems. Similar models and validation efforts are reviewed. Then, the main equations of the GN model are introduced. An intuitive physical interpretation of the equations and their features is proposed. The main characteristics of the non-linear interference (NLI) noise spectra that the GN model produces are discussed. To ease model exploitation, a new formulation in hyperbolic coordinates is proposed, which makes numerical integration faster. New approximate closed-form solutions are also provided. An extension of the GN model to distributed-amplification scenarios is introduced. NLI noise accumulation versus distance and bandwidth are studied in depth. Finally, the GN model implications as to system and networks design and optimization are discussed. © 1983-2012 IEEE. Source

A method for generating a channel code, in particular for a frame-header, wherein at least a code-word of the channel code is obtained by means of at least a concatenation of code-words of two constituent codes and such concatenation is performed on subsets of code-words of a first constituent code, having maximum length, with code-words of a second constituent code.

A method for segmenting the surface of a tyre including at least one groove, includes: irradiating a portion of the surface of the tyre by means of electromagnetic radiation having a wavelength in the visible spectrum; acquiring an image of the irradiated portion of the surface; and processing the image so as to segment it into regions corresponding to regions of the tyre which do or do not belong to the at least one groove. Additionally, processing the image so as to segment it includes: calculating a statistical quantity associated with the irradiation by electromagnetic radiation for each region of the image; and determining whether the region of the image does or does not belong to the at least one groove according to the value of the statistical quantity. Equipment for segmenting a surface of a tyre including at least one groove.

A textile electrode device, for detection of electrophysiological signals from the skin of a subject, having: a substrate designed to be positioned on the skin; at least a first detection electrode arranged on the substrate; and at least a first conducting element, carried by the substrate and electrically connected to the first detection electrode. The first detection electrode has a plurality of textile fibres, including conductive fibres and, optionally, fibres of a super-absorbent material, arranged in a direction substantially orthogonal to an upper surface of the substrate and reciprocally in contact with each other, so as to ensure uniform electrical contact over the entire first detection electrode. In particular, the first detection electrode is obtained by means of the flocking technique.
