Journal Article
Junejo, A. K., Komninos, N., & McCann, J. A. (2021). A Secure Integrated Framework for Fog-Assisted Internet-of-Things Systems. IEEE Internet of Things Journal, 8(8), 6840-6852. https://doi.org/10.1109/jiot.2020.3035474

Fog-assisted Internet-of-Things (Fog-IoT) systems are deployed in remote and unprotected environments, making them vulnerable to security, privacy, and trust challenges. Existing studies propose security schemes and trust models for these systems. Ho... Read More about A Secure Integrated Framework for Fog-Assisted Internet-of-Things Systems.

Wrinkling of a compressed hyperelastic half-space with localized surface imperfections (2020)
Journal Article
Fu. (2020). Wrinkling of a compressed hyperelastic half-space with localized surface imperfections. International Journal of Non-Linear Mechanics, https://doi.org/10.1016/j.ijnonlinmec.2020.103576

We consider a variant of the classical Biot problem concerning the wrinkling of a compressed hyperelastic half-space. The traction-free surface is no longer flat but has a localized ridge or trench that is invariant in the x1-direction along which th...

Rayleigh waves in micro-structured elastic systems: Non-reciprocity and energy symmetry breaking (2020)
Journal Article
Nieves, M., Carta, G., Pagneux, V., & Brun, M. (2020). Rayleigh waves in micro-structured elastic systems: Non-reciprocity and energy symmetry breaking. International Journal of Engineering Science, https://doi.org/10.1016/j.ijengsci.2020.103365

Rayleigh waves are analysed in elastic lattices incorporating inertial devices that couple in-plane displacements. The vector problems of elasticity for a triangular lattice and its long-wavelength/low-frequency continuum approximation are considered...

Assessing the usability of virtual learning environments in higher education (2020)
Thesis
Abuhlfaia, K. M. O. Assessing the usability of virtual learning environments in higher education. (Thesis). Keele University. https://keele-repository.worktribe.com/output/418095

Context: E-learning is an integral part of the modern higher education system, and therefore it is essential that students and staff are able to use systems that support E-learning, such as Virtual Learning Environments (VLEs), effectively. Usability... Read More about Assessing the usability of virtual learning environments in higher education.

Journal Article
(2020). On Developing and Validating Dynamic Systems: Simulation Engineering. https://doi.org/10.5381/jot.2020.19.3.a6

Dynamic systems, where the behaviour is the dominant characteristic, pose engineering challenges that are often neglected in model-based software engineering. However, supporting simulation development from design models is important in demonstrating... Read More about On Developing and Validating Dynamic Systems: Simulation Engineering..

Federated learning with hierarchical clustering of local updates to improve training on non-IID data (2020)
Journal Article
Fan. (2020). Federated learning with hierarchical clustering of local updates to improve training on non-IID data. International Joint Conference on Neural Networks, https://doi.org/10.1109/IJCNN48605.2020.9207469

Federated learning (FL) is a well established method for performing machine learning tasks over massively distributed data. However in settings where data is distributed in a non-iid (not independent and identically distributed) fashion -- as is typi...
