Harmonic mean SINR maximization in a cognitive radar with communication spectrum sharing

We investigate the shared spectrum access between a communication system and a radar which inspects multiple range gates with non-homogeneous interference. The degrees of freedom for system design are the radar waveform, the radar receive filters at each range gate, and the communication codebook. Assuming some cognition of the environment, we propose to maximize the harmonic mean of the signal-to-interference-plus-noise ratio across the range gates inspected by the radar under semi-definite ...

The duplicated body: a new form of dualism among preadolescents

Background. The use of social media is widespread among preadolescents, regardless the age restrictions that many providers and platforms have set. On these platforms, the massive representation of their bodies – often vehiculated as filtered images and/or altered videos – is negatively impacting their body image. Many of them experience feelings of insecurity and rejection during a time when their bodies are changing rapidly. This phenomenon is causing a new form of dualism between the perce...

Valle di Comino the bio-district for a sustainability of the rural landscape in southern Lazio

The Valle di Comino, recognized as an internal area within the National Strategy for Internal Areas, has been experiencing systemic fragility for several decades both in the demographic, with a constant decrease in the population, and economic, with a sharp decrease in the number of young farmers and a low rate of tourist accommodation, areas. In response to this marginality, partly due to the lack of the planners’ long-term outlook, a new development process has begun in this area based on...

The relevance of the Montessori method, in an authentically inclusive perspective

This contribution intends to highlight how much the relevance of the Montessori method does not lie in a single teaching practice, but as a whole, which creates a unitary path from childhood to adolescence under the sign of an education in which the know-how, the knowing how to be in oneself, knowing how to be with others and for others converge. Maria Montessori is internationally recognized as one of the innovators of pedagogy. Her method lays on solid scientific foundations confirmed by cu...

A novel turbo-assisted mild-hybrid configuration for a city car: Compressor electric drive characterization

The paper reports the preliminary results of a study to develop and prototype a novel compact hybrid powertrain for a small/medium urban vehicle. The aim is to improve a standard turbocharged gasoline engine's performance by utilizing various energy recovery systems. Most notable is a novel turbocharger with mechanically decoupled compressor and turbine. During operation, the turbine and compressor, which are connected to two different electric machines, contribute a net energy input to the b...
