The proper management of subsidence hazards requires a procedure to formulate thresholds and measurement & control loops. Such a formulation should be adequate in terms of technical hazard and hazard perception, unambiguous, in plain language and pre

This paper describes and deploys a workflow to assess the evolution of seismicity associated to injection of cold fluids close to a fault. We employ a coupled numerical thermo-hydro-mechanical simulator to simulate the evolution of pressures, tempera

The main science aim of the BlackGEM array is to detect optical counterparts to gravitational wave mergers. Additionally, the array will perform a set of synoptic surveys to detect Local Universe transients and short time-scale variability in stars a

Inversion of double-difference measurements from optical levelling for the Groningen gas field

Hydrocarbon extraction lead to compaction of the gas reservoir which is visible as subsidence on the surface. Subsidence measurements can therefore be used to better estimate reservoir parameters. Total subsidence is derived from the result of the

Dynamics of targeted ransomware negotiation

Autor: Ryan, Pierce, Fokker, John, Healy, Sorcha, Amann, Andreas

Publikováno v: IEEE Access Volume 10, 32836-32844, 2022

In this paper, we consider how the development of targeted ransomware has affected the dynamics of ransomware negotiations to better understand how to respond to ransomware attacks. We construct a model of ransomware negotiations as an asymmetric non
