Fourth Annual Workshop on A/B Testing and Platform-Enabled Learning Research

Learning engineering adds tools and processes to learning platforms to support improvement research. One kind of tool is A/B testing-common in large software companies and also represented academically at conferences like the Annual Conference on Digital Experimentation (CODE). A number of A/B testing systems focused on educational apps have...

Life lessons from and for distributed MPC – Part 1: Dynamics of cooperation

This paper and a second accompanying paper (Olaru et al., 2018) explore the potential of Distributed Predictive Control (DMPC) literature to provide valuable insights into social behaviour. In particular this first paper focuses on the mechanisms of group regulation in social systems. It will be noted that there are major differences between...

Life lessons from and for distributed MPC – Part 2: Choice of decision makers

This paper and an accompanying paper (McNamara et al., 2018) revisit the Distributed Predictive Control (DMPC) literature and seek to establish links with the social behaviour, focusing in particular on ways in which DMPC could be used to provide insights into the mechanisms of group regulation in social systems. It will be noted that there...

Centrifuge modelling of plate bearing tests

Current guidance given on plate bearing testing of granular soils suggests that the plate be at least five times the nominal size of the coarsest material. However this limiting ratio can have a huge influence on the reaction load required from plant and resources when conducted to confirm strength parameters used in the design of the sub grade...

High shear capacity ribbed piles

Ribbed bored piles are known to give increased shaft capacity in comparison to conventional straight shafted bored piles. The commercial benefit of greater pile capacity is cheaper foundations. Significant environmental benefits will also accrue from the use of efficient foundations that are able to carry higher load, leading to less excavation...

The London Geotechnical Centrifuge Centre at City University London

The London Geotechnical Centrifuge Centre located at City University, London is one of four currently active centrifuges in the UK. The centrifuge is well used and much of the geotechnical research at City University employs physical modelling but supported by a large element testing facility and numerical modelling capability. The centre was...
