Intruders which log-in through a series of machines when conducting an attack are hard to trace because of the complex architecture of the Internet. The thumbprinting method provides an efficient way to tracing such intruders by determining whether two connections are part of the same connection chain. Since many connections are transient, and therefore short in length, choosing the best time i...

Abstract This paper presents the Global Sensitivity Analysis of coefficients standard k- ε turbulence model used in RANS (Reynolds Averaged Navier-Stokes) simulations aimed to predict flow around a bi-dimensional hydrofoil operating at non-cavitating and cavitating regimes. The sensitivity analysis is treated by Sobol Decomposition, where Indices are computed through Polynomial Chaos Expansion ...

Abstract Data provenance is a form of knowledge graph providing an account what system performs, describing the data involved, and processes carried out over them. It crucial to ascertaining origin data, validating their quality, auditing applications behaviours, and, ultimately, making them accountable. However, instrumenting applications, especially legacy ones, track operations remains signi...
