Stacked Volume Holographic Gratings For Extending The Operational Wavelength Range In Led And Solar Applications, Sanjay Keshri, Julia Marín-Sáez, Izabela Naydenova, Kevin Murphy, Jesús Atencia, Daniel Chemisana, Sean Garner, María-Victoria Collados, Suzanne Martin

Articles

A novel stacking procedure is presented for volume phase holographic gratings (VPHGs) recorded in photopolymer material using Corning Willow Glass as a flexible substrate in order to achieve broader angular and spectral selectivity in a diffractive device with high efficiency for solar and LED applications. For the first time to our knowledge, we have shown a device designed for use with a white LED that has the same input and output angles and high efficiency when illuminated by different wavelengths. In this paper, two VPHGs were designed, experimentally recorded, and tested when illuminated at normal incidence. The experimental approach is …

School of Engineering, Computing and Mathematics

Decentralised environments with a high number of end-users and M2M devices used in several M2M services increasethe importance of a secure trust management and comprehensive trust evaluation system to avoid frauds from maliciousnodes. Blockchain, as part of the distributed ledger technology (DLT), helps to improve the overall security in a decentralised M2M community in various aspects. This research publication summarises several existing trust managementand evaluation approaches, concluding with their benefits and limitations. Besides these, it highlights the advantages ofthe distributed ledger technology with the focus on blockchain and consensus mechanisms. In this context, most relevantconsensus mechanisms are reviewed and an …


Smart Security Audit: Reinforcement Learning With A Deep Neural Network Approximator, Konstantin Pozdniakov, Eduardo Alonso, Vladimir Stankovic, Kimberly Tam, Kevin Jones Jan 2020

Smart Security Audit: Reinforcement Learning With A Deep Neural Network Approximator, Konstantin Pozdniakov, Eduardo Alonso, Vladimir Stankovic, Kimberly Tam, Kevin Jones

School of Engineering, Computing and Mathematics

A significant challenge in modern computer security is the growing skill gap as intruder capabilities increase, making it necessary to begin automating elements of penetration testing so analysts can contend with the growing number of cyber threats. In this paper, we attempt to assist human analysts by automating a single host penetration attack. To do so, a smart agent performs different attack sequences to find vulnerabilities in a target system. As it does so, it accumulates knowledge, learns new attack sequences and improves its own internal penetration testing logic. As a result, this agent (AgentPen for simplicity) is able to …

Master-Field Simulations Of O(A)-Improved Lattice Qcd: Algorithms, Stability And Exactness, Anthony Francis, Patrick Fritzsch, Martin Lüscher, Antonio Rago Jan 2020

Master-Field Simulations Of O(A)-Improved Lattice Qcd: Algorithms, Stability And Exactness, Anthony Francis, Patrick Fritzsch, Martin Lüscher, Antonio Rago

School of Engineering, Computing and Mathematics

In master-field simulations of lattice QCD, the expectation values of interest are obtained from a single or at most a few representative gauge-field configurations on very large lattices. If the light quarks are included, the generation of these fields using standard techniques is however challenging in view of various algorithmic instabilities and precision issues. Ways to overcome these problems are described here for the case of the O(α)-improved Wilson formulation of lattice QCD and the viability of the proposed measures is then checked in extensive simulations of the theory with flavours of quarks.


Maturity Model For Healthcare Cloud Security, Opeoluwa Ore Akinsanya Jan 2020

Maturity Model For Healthcare Cloud Security, Opeoluwa Ore Akinsanya

School of Engineering, Computing and Mathematics Theses

Management of security across eHealth cloud services is a major organizational challenge that healthcare organizations seek to resolve in order to aid their trusts in cloud and increase the adoption of cloud services in healthcare. The organizational challenges regarding implementations of technical security solutions are the major limiting factors for the adoption of the eHealth cloud. As such, the aim of this research will focus on developing a security maturity model, which will help healthcare organizations to provide a description of the application of their cloud security services, and an assessment and improvement of their cloud security services over time, …

User Profiling Based On Network Application Traffic Monitoring, Faisal Shaman Jan 2020

User Profiling Based On Network Application Traffic Monitoring, Faisal Shaman

School of Engineering, Computing and Mathematics Theses

There is increasing interest in identifying users and behaviour profiling from network traffic metadata for traffic engineering and security monitoring. However, user identification and behaviour profiling in real-time network management remains a challenge, as the activities and underlying interactions of network applications are constantly changing. User behaviour is also changing and adapting in parallel, due to changes in the online interaction environment. A major challenge is how to detect user activity among generic network traffic in terms of identifying the user and his/her changing behaviour over time. Another issue is that relying only on computer network information (Internet Protocol [IP] …

Effective Online Safety Awareness For Young People In Less Developed Countries, Kona Ramesswar Kona Herkanaidu Jan 2020

Effective Online Safety Awareness For Young People In Less Developed Countries, Kona Ramesswar Kona Herkanaidu

School of Engineering, Computing and Mathematics Theses

In less developed countries (LDCs) there is a research deficit on the positive and negative aspects of their respective emerging digital cultures. Education programmes that seek to raise awareness of online safety, needs to be based on evidence and not simply transposed from other countries as the issues involved may be very different. Thailand, in particular, has very little data that can be used to create meaningful educational material. This was determined after a thorough literature review which found that most of the research has been carried out in the advanced economies of North America, Europe and Australasia. By contrast …
