Title: On the abelian coverings of curves over finite fields.

Abstract: The main result of this talk identifies when two curves over finite fields have equivalent categories of (possibly ramified) abelian coverings.  We will also sketch where this result fits in the wider context of number theoretic analogs of the Kac's famous question: "Can you hear the shape of a drum?".

Title: Operations research solutions to improve the quality of healthcare

Abstract: Healthcare expenditures are increasing in many countries. Delivering adequate quality of healthcare requires efficient utilization of resources. Operations Research allows us to maintain or increase the current quality of healthcare for a growing number of patients without increasing the required work force. In this talk, I will describe a series of mathematical results obtained in the Center for Healthcare Operations Improvement and Research of the University of Twente, and I will indicate how these results were implemented in Dutch hospitals.
Efficient planning of operating theatres will reduce the wasted hours of staff, balancing the number of patients in wards will reduce peaks and therefore increases the efficiency of nursing care, efficient rostering of staff allows for more work to be done by the same number of people. While employing operations research techniques seems to be dedicated to improving efficiency, at the same time improved efficiency leads to increased job satisfaction as experienced workload is often dominated by those moments at which the work pressure is very high, and it also improves patient safety since errors due to peak work load will be avoided.
