In Romania the 202 analysed eggs were Salmonella free, where...

This might be explained by the fact that most ICSs do not provide source code access. In most cases, this means that only persons w...

Being able to identify a space to park their cars can lead many drivers to drive around the intended parking area several times, increasing traffic density and pollution. In this research we propose a collaborative blockchain solution with gamification for parking. Users collaborate to report free spaces and receive free parking minut...
