Solid-State Transformers with Input-Series/Output- Parallel configuration offer a convenient solution for AC/DC power conversion, thanks to their modularity, scalability and flexibility. However, as known, they are affected by a second-order harmonic rippl ...
This paper proposes a novel full passive magnetic levitation motor without active magnetic suspension. It has a magnetic levitation unit and a motor unit. The Halbach array permanent magnets and a pyrolytic graphite (PG) disk realize the full passive magne ...
Sustainability is a constant search for balance between the needs and the means implemented, which implies meeting the needs present without compromising those of generations to come. Later generations will indeed imperative to consider. So that their scop ...
Collections of interacting active particles, self-propelling or not, have shown remarkable phenomena including the emergence of dynamic patterns across different length scales, from animal groups to vibrated grains, microtubules, bacteria, and chemicalor f ...
The metropolis can be analysed as an infrastructure in perpetual motion, composed of built elements – the system “hardware” – and social networks – the system “software”. The emergence of an overall city-scale infrastructure composed not of a single unit b ...
Traffic congestion and ground space scarcity are increasing the need to find more space in the urban underground. The demand-driven "top-down" planning of Urban Underground Space (UUS) is common worldwide. As natural resource, the endowments of UUS are dif ...
