This paper describes a simulation-based approach for automated risk assessment of complex cyber-physical systems to support implementers of ISO 27005. The approach is based on systematic cause-and-effect modelling of threats, their causes and effects, and the ways in which the effects of one threat can lead to other threats. In this way, the approa...
The cybersecurity landscape is particularly challenging for SMEs. On the one hand, they must comply with regulation or face legal sanction. But on the other, they may not have the resource or expertise to ensure regulatory compliance, especially since this is not their core business. At the same time, it is also well-attested in the literature that...
Technology adoption is often predicted based on little information such as the Perceived ease-of-use and the Perceived usefulness of the technology. Related constructs such as Attitude to use, Behavioral intention to use and External variables cannot be easily operationalised and so are often ignored. However, technology characteristics themselves...

This enables automated provisioning and management of microservices delivering a service function chain, which affords...
Operators have been adopting the cloud‐native paradigm for the roll‐out of 5G architecture. With it goes the introduction of the service‐based architecture as a key design pattern for realizing future control‐ and ultimately user‐planes of mobile networks. The main benefits of this new design pattern are increased flexibility, meaning new business...
When deploying a digital media service on the FLAME platform, you are placing it in a responsive environment that reacts (using behaviours you have defined) in real-time to metrics of interest to you. Considering this behaviour as a continuous cycle of optimization in which your target user experience (UX) is negotiated with the most efficient use...

Digital health data is created, stored and processed in healthcare IT infrastructures. These infrastructures are the target of large-scale cyber-attacks and are found to be vulnerable, primarily for two main reasons: the heterogeneity of infrastructure and the numerous stakeholders (medical staff, managers, patients, regulators etc.). Furthermore,...

The rapid evolution of the cloud market is leading to the emergence of new services, new ways for service provisioning and new interaction and collaboration models both amongst cloud providers and service ecosystems exploiting cloud resources. Service Level Agreements (SLAs) govern the aforementioned relationships by defining the terms of engagemen...
STEER envisages a community-centric digitally-based ecosystem which it refers to as “Social Telemedia” as a cross-breeding of social networks and networked media. According to STEER, the Future Social Telemedia Lifecycle will revolve around media services that user communities can both autonomously build and enjoy exploiting smart tools and specifi...

Service Level Agreements (SLA) include quality of service
(QoS) constraints and bounds that have to be honoured by the service
provider. To maximise the Service Provider revenue while satisfying the
QoS requirements of the agreed SLAs it is important to be able to per-
form a dynamic distribution of the service provider resources between
the servic...

Reversible Digitally Filtered Molecular Dynamics (RDFMD) is a method of amplifying or suppressing motions in a molecular dynamics simulation, through the application of a digital filter to the simulation velocities. RDFMD and its derivatives have been previously used to promote conformational motions in liquid-phase butane, the Syrian hamster prion...
The Hilbert−Huang transform (HHT) is a new method for the analysis of nonstationary signals that allows a signal's frequency and amplitude to be evaluated with excellent time resolution. In this paper, the HHT method is described, and its performance is compared with the Fourier methods of spectral analysis. The HHT is then applied to the analysis...
It has recently been shown that digital filtering methods may be used to selectively enhance or suppress the vibrational motion in a molecular dynamics computer simulation solely on the basis of frequency (J. Chem. Phys. 2000, 112, 2586−2597). The method of digitally filtered molecular dynamics (DFMD) does, however, suffer from a number of disadvan...
A new method for modifying the course of a molecular dynamics computer simulation is presented. Digitally filtered molecular dynamics (DFMD) applies the well-established theory of digital filters to molecular dynamics simulations, enabling atomic motion to be enhanced or suppressed in a selective manner solely on the basis of frequency. The basic t...
