Evaluating The Risks Of Human Factors Associated With Social Media Cybersecurity Threats, Fai Ben Salamah, Marco A. Palomino, Maria Papadaki, Matthew J. Craven, Steven Furnell

School of Engineering, Computing and Mathematics

Human behaviors and attitudes play a significant role in cybersecurity. However, studies to quantify the impact of such behaviors and attitudes are scarce, and they are not always considered when developing mitigation strategies. To compensate for this, we have looked into a large sample of employees with different levels of expertise and backgrounds across a variety of industrial sectors and organizations. We have found that age and job role constitute the main human factors associated with social media cybersecurity risks. We can confirm that the youngest employees are the most risk prone within an organization, and the employees working in …

A Two-Dimensional Double Layer-Averaged Model Of Hyperconcentrated Turbidity Currents With Non-Newtonian Rheology, Yining Sun, Ji Li, Zhixian Cao, Alistair George Liam Borthwick Jan 2023

A Two-Dimensional Double Layer-Averaged Model Of Hyperconcentrated Turbidity Currents With Non-Newtonian Rheology, Yining Sun, Ji Li, Zhixian Cao, Alistair George Liam Borthwick

School of Engineering, Computing and Mathematics

Hyperconcentrated turbidity currents typically display non-Newtonian characteristics that influence sediment transport and morphological evolution in alluvial rivers. However, hydro-sediment-morphological processes involving hyperconcentrated turbidity currents are poorly understood, with little known about the effect of the non-Newtonian rheology. The current paper extends a recent two-dimensional double layer-averaged model to incorporate non-Newtonian constitutive relations. The extended model is benchmarked against experimental and numerical data for cases including subaerial mud flow, subaqueous debris flow, and reservoir turbidity currents. The computational results agree well with observations for the subaerial mud flow and independent numerical simulations of subaqueous debris flow. Differences between the non-Newtonian and …

Earth's Critical Zone (CZ), the near-surface layer where rock is weathered and landscapes co-evolve with life, is profoundly influenced by the type of underlying bedrock. Previous studies employing the CZ framework have focused primarily on landscapes dominated by silicate rocks. However, carbonate rocks crop out on approximately 15% of Earth's ice-free continental surface and provide important water resources and ecosystem services to ∼1.2 billion people. Unlike silicates, carbonate minerals weather congruently and have high solubilities and rapid dissolution kinetics, enabling the development of large, interconnected pore spaces and preferential flow paths that restructure the CZ. Here we review the state …

Interconnection Schemes In Modeling And Control, Pablo Borja, Joel Ferguson, Der Schaft A Van Jan 2023

Interconnection Schemes In Modeling And Control, Pablo Borja, Joel Ferguson, Der Schaft A Van

School of Engineering, Computing and Mathematics

Interconnection schemes are ubiquitous in physical systems. For instance, in multi-domain systems consisting of interconnected subsystems from different physical domains. Furthermore, the interconnection of two or more systems has also been exploited to analyze and control dynamical systems, especially passive ones. To this end, the most common interconnection structure is the negative feedback interconnection. However, this approach is unsuitable to directly couple the states of the subsystems in the overall system’s energy as customarily occurs in physical systems. This letter provides two interconnection approaches that overcome this issue. Notably, it is shown that these interconnection structures are suitable for decomposing …
