Recently proposed active queue management mechanisms can minimise the time packets spend enqueued at a network bottleneck by deploying shallow buffers with short-term burst tolerance. However, this shallow buffering causes noticeable performance degradation in the throughput for a path delay is higher above typical intra-country levels. Using a less-aggressive backoff...

Environmental Fluid Mechanics (EFM) has emerged at the interfaces of fluid mechanics, hydraulics, hydrology, oceanography, and meteorology to deal with multiple problems involving environmental fluid flows. The talk will briefly introduce EFM and outline the typical problems addressed by this fairly new discipline. Then, a few ‘snapshots’ of EFM will...

Seminar talk by Ilmar Ferreira Santos, Department of Mechanical Engineering, Technical University of Denmark, Denmark.

Launching material into orbit is a hugely expensive business. But rather than lifting material from the bottom of the Earth's deep gravity well, perhaps we can use material that's already out there.

A group that promotes engineering as a career choice for young people is hosting a key seminar at the University of Aberdeen later this month.

In this lecture I will examine nature of subtle phenomenon such grazing bifurcations occurring in non-smooth systems. I will start with linear oscillators undergoing impacts with secondary elastic supports, which have been studied experimentally and analytically for near-grazing conditions [1]. We discovered a narrow band of chaos close to the...

Horizontal Axis Wind Turbines (HAWTs) are increasingly being deployed in large wind farms, the largest being in many cases offshore. This seminar will discuss the aerodynamic modelling of wind flow through large wind farms and how turbine operation may be controlled in order to maximise energy capture while minimising fatigue...

Approximately 90% of everything we use involves a catalytic process at some part of its life cycle and more than 80% of current industrial processes established since 1980 in the chemical, petrochemical and biochemical industries, as well as in the production of polymers and in environmental protection, use catalysts. Of...
