A study case of noise coming from road yard machines: Experimental tests and theoretical formulas to evaluate sound impact on people

Sound levels emitted by road yard machines are correlated strictly to engine power, to level of power taken up during the different operative conditions, to ground morphologies and features, to maintenance state of machines and to meteo-climatic conditions during working period. If people could carry out a preventive evaluation of sound diffusion around working machines than they could single out the yard zones where the acoustic limits established by Italian environmental laws would be overc...

Applying a DSP to seismic monitoring

An approach to the detection of the starting time of an earthquake that operates in the frequency domain is presented. It is based on the use of a digital signal processor chip. The key is the device's ability to perform both a real-time spectrum analysis of the signal and a fast computation of a suitable function able to highlight the starting of the earthquake. The validity of the approach is established through several examples and a comparison with other tools that work in the time domain.

Future intention to use Metaverse with VR headsets: Integrating self-determination theory and theory of planned behaviour

The adoption of Metaverse platforms remains limited, with diverse user experiences posing challenges for consistent sampling in research. Most studies frequently combine data from users interacting with the Metaverse through different devices or from potential users; however, these samples are often unreliable. Conversely, this study concentrates solely on active users who interact with the Metaverse using VR headsets, employing a combined framework of self- determination theory and the theor...
