Brief Description:In this talk I will give an overview of some of the work I have done on developing queueing models for performance evaluation and optimization of healthcare delivery systems. In the first part, I present a new computational methodology for service evaluation of emergency admission units facing time-dependent admission rates. In the second part, I will show how a combination of simulation and queueing models could be used for finding the optimal staffing profiles in accident and emergency departments.

I will talk about the design of (declarative) configuration languages, in particular the differences between these languages and programming languages. I will then talk about some "work in progress" by illustrating the difficulties which can arise in attempting to identify "provenance" of configuration parameters, and the implications for the design of new configuration languages and tools.

Brief Description:In mobile communication, spatial queries pose a serious threat to user location privacy because the location of a query may reveal sensitive information about the mobile user. In this paper, we study k nearest neighbor (kNN) queries where the mobile user queries the location-based service (LBS) provider about k nearest points of interest (POIs) on the basis of his current location. We propose a solution for the mobile user to preserve his location privacy in kNN queries.
