Nomura lecture 2013

This year's Nomura Lecture will be held on the 6th June 2013, by Paul Milgrom, Shirley and Leonard Ely Professor of Humanities and Sciences at Stanford University. He is well known for his fundamental contributions to auction theory and incentive theory. He is also an excellent speaker

Time/location: 5.30pm Martin Wood Lecture Theatre

TitleStrategy-Proof Auctions for Complex Procurement

AbstractSome real resource allocation problems are so large and complex that optimization would computationally infeasible, even with complete information about all the relevant values. For example, the proposal in the US to use television broadcasters' bids to determine which stations go off air to make room for wireless broadband is characterized by hundreds of thousands of integer constraints. We use game theory and auction theory to characterize a class of simple, strategy-proof auctions for such problems and show their equivalence to a class of "clock auctions," which make the optimal bidding strategy obvious to all bidders. We adapt the results of optimal auction theory to reduce expected procurement costs and prove that the procurement cost of each clock auction is the same as that of the full information equilibrium of its related paid-as-bid (sealed-bid) auction.

Power and network problems earlier today

There were several electrical outages in Oxford earlier today that affected both the St Giles building and Dartington House. The electrical problems began about 5:48am and lasted until about 8:20. Southern Electric say two faults on their high voltage network caused the problems. Reports of an explosion in central Oxford this morning was actually the sound caused by large fuses breaking during a fire at an electricity sub station on Parks Road which further affected power to university buildings.

Although the departmental IT services largely weathered the electrical problems, the outages took out part of the university backbone network and hence left the departmental network inaccessible from outside the department (and also partially unusable within the department due to the backbone network outage preventing connection between buildings) until about 10am when power was restored to the failed section of the university backbone.

A network switch serving the 3rd floor of the St Giles building suffered an unrecoverable fault during the outages. It was replaced at 14:00 restoring service.

If you find problems with a desktop machine that are not resolved by rebooting it/turning it off and on again, or have problems with any other maths IT services please report the issue to help [-at-] maths [dot] ox [dot] ac [dot] uk as normal.

Titchmarsh Fellowships

The Mathematical Institute has just announced the availability of up to 4 prestigious Titchmarsh Fellowships in a range of subjects including mathematical and computational finance. Applications are due on December 10, 2012.

Network outage in the Gibson Building again

The network connection for the Gibson Building has failed again at 8:35am on Saturday 2nd June. It is likely this is another failure of the OUCS equipment that provides the network connection.

Update (2:25pm 2/6/2012): a creative workaround has once again been put in place to bypass the failed OUCS equipment and restore service.

We would expect OUCS may not investigate the repeat problem with their equipment until Wednesday but would hope when they do the problem is satisfactorily resolved this time.

Network outage in Gibson Building

Due to a UPS failure, there is currently no network connectivity in the Gibson Building.  The outage began around 18:00 this evening.  The network equipment belongs to OUCS, who have been notified.  Until OUCS can investigate and repair the fault, there will be no network related services available in the Gibson Building - this will include internet access, access to workstations, home directories, and printing.

Update (2:15pm 26/5/2012): a creative workaround has now been put in place to bypass the failed OUCS equipment and restore service. When OUCS fix their equipment next week the bypass will need removing which will result in a short outage of a few minutes.

Update (17:30 28/05/2012): the UPS unit has been fixed, and the workaround removed

Departmental Mail System down

The departmental mail system suffered a fault at about 11:25am today and is currently down. Work is underway to restore service as quickly as possible.

Service was restored by 12:20pm.

Mailserver experiences ongoing performance issues

There are currently some ongoing performance issues with the mailserver, which are being investigated. You are most likely to experience those via lagging responsiveness of your mail client or the Zimbra web interface. An update will be posted here, once the issues have been resolved.

Various changes and adjustments to the mail system have been taking place over the recent weeks to improve performance and eliminate the issues. The final changes are expected to all be in place by Easter.
