Although the automotive industry is rapidly shifting to electric cars, Hybrid Electric Vehicles (HEVs) – with both an electric motor and an internal combustion engine – will still dominate for the next half century. Read more
An important goal in highway traffic management is event detection – finding ways to use real-time data to alert authorities to potential problems as they begin to emerge. Read more
A particle following a classical random walk on a finite graph will explore the system completely, in time visiting every site repeatedly. The process is ergodic. Read more
Since ancient times, scientists have sought to identify precursory signals which might allow the prediction of impending earthquakes or volcanic eruptions. Read more
The addition of stochastic noise to a deterministic dynamical system can induce dramatic qualitative changes in its behaviour. In one counterintuitive effect – termed noise induced order – the addition of noise to an already chaotic system can make its behaviour more orderly and regular. Read more
Dividing things into categories is a human habit, helping us to learn and understand the external world, as well as to share and communicate knowledge. Read more
In nonlinear dynamics, a chimera refers to a dynamical hybrid – a state in a network of identical coupled oscillators exhibiting a mix of both synchronous and asynchronous behaviour. Read more
In most of the developing world, individual wealth tends to increase with city size, making migration an important avenue for poverty reduction. Read more
In 19th-century casinos, most common betting took the form of even-money bets placed on red or black in games such as Roulette. Strategy lay in deciding how much to wager on each bet, and when to quit playing. Read more
