Identifying the recurrence patterns of non-volcanic tremors using a 2-D hidden Markov model
Posted on
by
Tectonic movements create stress within the Earth’s crust, which gets released in sudden earthquakes, but also in less dramatic slow slip events. Such events are sometimes accompanied by so-called non-volcanic tremors – weak seismic signals of extended duration along major faults.

Final presentations from the 2018 LML Summer School now online
Posted on
by
The LML Summer School for 2018 ran from mid-July to mid-August and was a great success, with eight students collaborating on projects supervised by LML Fellows. The students made their final presentations on 17 August, and these are now available online, links […]

Do environmental concerns affect commuting choices? Hybrid choice modelling with household survey data
Posted on

Addressing climate change is among the top challenges facing governments around the world, requiring drastic reductions of greenhouse gas emissions. In part this will be through new technologies but progress will also require encouraging significant changes in day-to-day human behaviour.

In Southern California, Japan, Indonesia or other areas around the world prone to earthquakes, people at risk face vast uncertainty about when, where, and how strong the next one will be.

Quantification of systemic risk from overlapping portfolios in the financial system
Posted on
by
Systemic risk in the financial system is risk tied not to one specific firm, but to the interactions between firms – for example, through possible avalanches of spreading financial distress. One important form of systemic risk arises from indirect links between financial […]

Studying language evolution in the age of big data

The availability of large digital corpora of cross-linguistic data is revolutionizing many branches of linguistics, triggering a shift of study from detailed questions about individual features to more global patterns amenable to statistical analyses.

Phase transition, scaling of moments, and order-parameter distributions in Brownian particles and branching processes with finite-size effects
Posted on
by
Random walks provide precise mathematical models for diffusion processes, while rooted trees offer a geometric representation of branching processes. Both are of broad importance in probability theory and statistical physics, and some important mathematical results establish links between the two.

Predicting chaos with an optimal combination of data and prior knowledge
Posted on

Early in the 20th century, experts tried to forecast the weather by noting current conditions, patterns of winds, temperatures and air pressures, and looking into historical records to find previous moments when similar conditions prevailed. Looking a few days forward in the […]

Synchronisation and Extreme Value Theory for Coupled Map Lattices
Posted on
by
Coupled Map Lattices (CML) are discrete time and space dynamical systems often used as simplified models for the study of spatially-extended non-linear systems.
