The change in diameter of retinal vessels as a function of increasing distance to the optic disc is believed to be indicative of the risk level of various vascular diseases such as generalised arteriosclerosis and Diabetes Mellitus. In particular, focal arteriolar narrowing (FAN) is considered related to arteriosclerosis. The aim of this work is to develop(More)
even small-scale sensor networks need to be carefully designed, programmed and deployed to meet user goals, such as lifetime or quality of the collected data. Only by confronting the problems that do come up during actual deployments can we devise the tools, methods and abstractions that will help meet the requirements of a sensor network infrastructure.

The databases of today have to handle high load while providing high availability. The solution often used to cope with these requirements is a cluster. In this paper we implement a load-balancer for MySQL; a widely used open source database. Within this load-balancer we have implemented different algorithms to distribute load. We present benchmarks for the(More)
Sensor networks are not yet tools that scientists can use to densely sample phenomena that were previously hard or impossible to observe in-situ. Even small-scale sensor networks need to be carefully designed, programmed and deployed to meet experimental goals in terms of experiment duration or quality of the collected data. Only by confronting the problems(More)
