Standard cost of italian metro services: The influence of automatism, wheels technology and capacityIn this paper, we measure the standard cost of light metro (LM) and heavy metro (HM) Italian services based on the cost model provided by Avenali et al., (2018). The cost model takes into account technological characteristics that may drive cost differentials, such as the degree of automatism of...

Schemes for the identification and replacement of two-faced Byzantine processes are presented. The detection is based on the comparison of the (blackbox) decision result of a Byzantine consensus on input consisting of the inputs of each of the processes, in a system containing n processes p1, …, pn...

Spectral techniques have proved amongst the most effective approaches to graph clustering. However, in general they require explicit computation of the main eigenvectors of a suitable matrix (usually the Laplacian matrix of the graph). Recent work (e.g., Becchetti et al., SODA 2017) suggests that...

In this paper, we propose and report a study of a low latency resource sharing protocol for Fog Computing. The protocol has its root in the power-of-random choices family of randomization protocol. The protocol, dubbed $LL_g(T)$ is designed to cope with a not homogeneous set of nodes and dealing...

One of the main issues in digital forensics is the management of evidences. From the time of evidence collection until the time of their exploitation in a legal court, evidences may be accessed by multiple parties involved in the investigation that take temporary their ownership. This process,...

Computer networks are undergoing a phenomenal growth, driven by the rapidly increasing number of nodes constituting the networks. At the same time, the number of security threats on Internet and intranet networks is constantly growing, and the testing and experimentation of cyber defense solutions...
