How do I use this calendar?

You can click on an event to display further information about it.

The toolbar above the calendar has buttons to view different events. Use the left and right arrow icons to view events in the past and future. The button inbetween returns you to today's view. The button to the right of this shows a mini-calendar to let you quickly jump to any date.

The dropdown box on the right allows you to see a different view of the calendar, such as an agenda or a termly view.

If this calendar has tags, you can use the labelled checkboxes at the top of the page to select just the tags you wish to view, and then click "Show selected". The calendar will be redisplayed with just the events related to these tags, making it easier to find what you're looking for.

Paolo Pagano (St Andrews): 'Contribution of coupling of Alfvén and kink modes to coronal heating'
Abstract: Recent observations of coronal loops reveal ubiquitous transverse velocity perturbations, that undergo strong damping as they propagate. Observational estimates show that these perturbations contain significant amounts of energy. We have previously demonstrated that this observed rapid damping can be understood in terms of coupling of different wave modes in the inhomogeneous boundaries of the loops: this mode coupling leads to the coupling of the transversal (kink) mode to the azimuthal (Alfvén) mode, observed as the decay of the transverse kink oscillations. However, an important point to note here is that (observed) wave damping does not automatically imply dissipation, and hence heating. To investigate under which circumstances this process can contribute to the coronal heating and to what extend the heating rate is sustainable, we perform 3D numerical experiments modelling the observed, transverse oscillations including the effects of resistivity and thermal conduction. We first analyse the contribution from a single monochromatic pulse, and then we extend the study by investigating different sizes and structures of the boundary layer and a continuous driver.

The scheme aims to help UK universities build capacity and promote collaborations by facilitating visits by distinguished international experts. It provides funding to enable an academic engineering department in a UK university to be a host for up to one month to a Distinguished Visiting Fellow from an overseas academic centre of excellence.

Scheme objectives:

    • access global centres of excellence in engineering research and teaching, with a view to strengthening UK capacity and international standing and promoting new international collaborations;
      • enable participating organisations to discover shared and complementary skills, areas and initiatives that could form the foundation for future collaborations and strategic research alliances;
        • foster knowledge exchange partnerships through the sharing of skills, experience, information and the latest technological developments;
          • promote the unification of participating organisations’ diverse knowledge in the area of engineering and technology by enabling the host institution to engage the Visiting Fellow in a range of mutually beneficial activities.

          These activities may include:

            • Working collaboratively on joint papers and research proposals to tackle ambitious research problems or challenges;
              • Delivering lectures, presentations, seminars, demonstrations, and expert workshops to graduates, undergraduates, members of the host faculty and academics from other UK institutions;
                • Establishing project consortia to work collaboratively on ambitious joint research projects.
