In terms of cost and deployment time, radio communication for aerial vehicles will greatly benefit from the ready-to-market infrastructure ...

Adolescent Gambling, Gambling Expenditure and Gambling?Related Harms in Finland, 2011?2017

Existing literature on recent trends in adolescent gambling is scarce. The rapidly changing landscape of gambling, together with the generally applied legal age limits, calls for the continuous monitoring of gambling also among the adolescent population. In Finland, the legal gambling age is 18. We examined changes in adolescents? gambling, ...

Exact NFDM Transmission in Presence of Fiber-Loss

Nonlinear Fourier transform (NFT) based fiber optic communication techniques so far have been applied to the nonlinear Schroedinger equation (NLSE) that models signal propagation in a lossless optical fiber. Conventionally, the lossy propagation of signal is approximated by a lossless propagation using the path-average approach which makes the propagation model ...

Enabling Multicast and Broadcast in the 5G Core for Converged Fixed and Mobile Networks

© 1963-12012 IEEE. The fifth generation of cellular technologies, 5G, promises to deliver a wide variety of services. However, the first release of 5G (3GPP Rel-15) did not consider multicast capabilities in the 5G system including both access and core networks. This article fills the gap by describing solutions for ...

PepMusic: motivational qualities of songs for daily activities

  • Aiello L.
  • Kim Y.
  • Quercia D.

Music can motivate many daily activities as it can regulate mood, increase productivity and sports performance, and raise spirits. However, we know little about how to recommend songs that are motivational for people given their contexts and activities. As a first step towards dealing with this issue, we adopt a ...
