In contrast to human soccer players, autonomous robot soccer players often move according to a limited set of predefined behavioural rules. This knowledge can be used advantageously: If the opponent’s behavioural rules are learned, it will be possible to detect these during a match and react accordingly. A method for autonomous activity mining in videos, called Probabilistic Latent Sequential M...

Process mining focuses on the discovery of knowledge about a (business) process from a set of its executions stored in an event log. Each event describes an activity and its performer. Process mining techniques allows automatically extracting the process model that gains insight into various perspectives, such as the control flow perspective, data, and organizational perspective. In this paper,...

Unsteady mixed convection flows in a lid-driven square cavity filled with a fluid-saturated porous medium is investigated numerically. The two vertical walls of the enclosure are insulated while the bottom wall is cooled. The top wall is heated sinusoidally and moving at a constant speed. The governing equations are solved numerically by using finite volume method with SIMPLE algorithm. The res...

The unsteady viscous flow in the vicinity of an axisymmetric stagnation point of an infinite moving cylinder with time-dependent axial velocity is investigated. The impinging free stream is steady with a strain rate k. An exact solution of the Navier-Stokes equations is derived in this problem. A reduction of these equations is obtained by use of appropriate transformations. The general self-si...

West Nile virus spread rapidly from east to west across North America, despite the north-south migratory flyways of its avian hosts. In this issue, Venkatesan & Rasgon (2010) present new data on the population genetics of Culex tarsalis, the dominant West Nile virus vector in the Western United States, suggesting that patterns of mosquito gene flow may better reflect the virus's expansion from ...
