A multi-scale integrated assessment model to support urban sustainability (2021)
Journal Article
Purvis, B., Mao, Y., & Robinson, D. (2022). A multi-scale integrated assessment model to support urban sustainability. Sustainability Science, 17(1), 151-169. https://doi.org/10.1007/s11625-021-01080-0

Tools purposed towards supporting the transition to more sustainable urban futures typically focus on specific phenomena at the local level. Whilst such approaches remain valuable, there is a need to complement this micro approach with broader integr...

Despite the progress in the field of automatic public transport route optimisation in recent years, there exists a clear gap between the development of optimisation algorithms and their applications in real-world planning processes. In this study, we... Read More about Public transport network optimisation in PTV Visum using selection hyper-heuristics.

An adaptive scaled network for public transport route optimisation (2019)
Journal Article
Heyken Soares, P., Mumford, C. L., Amponsah, K., & Mao, Y. (2019). An adaptive scaled network for public transport route optimisation. Public Transport, 11(2), 379-412. https://doi.org/10.1007/s12469-019-00208-x

We introduce an adaptive network for public transport route optimisation by scaling down the available street network to a level where optimisation methods such as genetic algorithms can be applied. Our scaling is adapted to preserve the characterist... Read More about An adaptive scaled network for public transport route optimisation.

Entropy and its Application to Urban Systems (2019)
Journal Article
Purvis, B., Mao, Y., & Robinson, D. (2019). Entropy and its Application to Urban Systems. Entropy, 21(1), Article 56. https://doi.org/10.3390/e21010056

Since its conception over 150 years ago, entropy has enlightened and confused scholars and students alike, from its origins in physics and beyond. More recently, it has been considered within the urban context in a rather eclectic range of applicatio... Read More about Entropy and its Application to Urban Systems.

Bio-inspired hierarchical designs for stiff, strong interfaces between materials of differing stiffness (2018)
Journal Article
Rayneau-Kirkhope, D., Mao, Y., & Rauch, C. (2018). Bio-inspired hierarchical designs for stiff, strong interfaces between materials of differing stiffness. Physical Review Applied, 10(3), 1-10. https://doi.org/10.1103/PhysRevApplied.10.034016

Throughout biology, geometric hierarchy is a recurrent theme in structures where strength is achieved with efficient material usage. Acting over vast timescales, evolution has brought about beautiful solutions to problems of mechanics that are only n...

Three pillars of sustainability: in search of conceptual origins (2018)
Journal Article
Purvis, B., Mao, Y., & Robinson, D. (2019). Three pillars of sustainability: in search of conceptual origins. Sustainability Science, 14(3), 681-695. https://doi.org/10.1007/s11625-018-0627-5

The three pillar conception of (social, economic and environmental) sustainability, commonly represented by three intersecting circles with overall sustainability at the centre, has become ubiquitous. With a view to identifying the genesis and theore... Read More about Three pillars of sustainability: in search of conceptual origins.

Thermodynamic entropy as an indicator for urban sustainability? (2017)
Journal Article
Purvis, B., Mao, Y., & Robinson, D. (in press). Thermodynamic entropy as an indicator for urban sustainability?. Procedia Engineering, 198, https://doi.org/10.1016/j.proeng.2017.07.131

As foci of economic activity, resource consumption, and the production of material waste and pollution, cities represent both a major hurdle and yet also a source of great potential for achieving the goal of sustainability. Motivated by the desire to... Read More about Thermodynamic entropy as an indicator for urban sustainability?.

Ultra-light hierarchical meta-materials on a body-centred cubic lattice (2017)
Journal Article

Modern fabrication techniques offer the freedom to design and manufacture structures with complex geometry on many lengthscales, offering many potential advantages. For example, fractal/hierarchical struts have been shown to be exceptionally strong a... Read More about Ultra-light hierarchical meta-materials on a body-centred cubic lattice.

Delayed response in the Hawk Dove Game (2017)
Journal Article

We consider a group of agents playing the Hawk-Dove game. These agents have a finite memory of past interactions which they use to optimize their play. By both analytical and numerical approaches, we show that an instability occurs at a critical memo... Read More about Delayed response in the Hawk Dove Game.

Journal Article
Farr, R., & Mao, Y. (2016). Optimal Counter-current exchange networks. Physical Review E, 94(5), https://doi.org/10.1103/PhysRevE.94.052410

We present a general analysis of exchange devices linking their efficiency to the geometry of the exchange surface and supply network. For certain parameter ranges, we show that the optimal exchanger consists of densely packed pipes which can span a... Read More about Optimal Counter-current exchange networks.

Forgetfulness can help you win games (2015)
Journal Article

We present a simple game model where agents with different memory lengths compete for finite resources. We show by simulation and analytically that an instability exists at a critical memory length, and as a result, different memory lengths can compe...

Scaling behavior near jamming in random sequential adsorption (2015)
Journal Article

For the Random Sequential Adsorption model, we introduce the ‘availability’ as a new variable corresponding to the number of available locations in which an adsorbate can be accommodated. We investigate the relation of the availability to the coverag... Read More about Scaling behavior near jamming in random sequential adsorption.

Hierarchical and fractal designs have been shown to yield high mechanical efficiency under a variety of loading conditions. Here a fractal frame is optimized for compressive loading in a two-dimensional space. We obtain the dependence of volume requi...
