Locating leakages in networks
Leakages in a water distribution network can be found through a smart combination of measurements and a computational model.
Tidal prediction system
Research institute Deltares has developed a new instrument for tidal prediction for the Dutch Ministry for Infrastructure and the Environment. It is called FEWS-Noordzee and combines a large number of innovations.
The Dutch sewer system has a length of more than 10.000 km. Monitoring this system is now primarily done by visual inspections. That is expensive and hardly effective. Together with engineering company Witteveen+Bos, VORtech developed methods for automatic monitoring of sewer systems. The methods use observations that are relatively easy to obtain or are even already gathered.
The IMAGE model describes the global environmental changes that take place as a result of human activities. VORtech has made several extensions to the model code.
For over 15 years, VORtech contributed significantly to the the maintenance of the software that the Dutch Ministry of Infrastructure and the Environment uses for its water management.
Light pollution model
When designing a lighting plan for a new living quarter or industrial area, the legal boundaries on light pollution should not be crossed. VORtech developed an application that shows the expected light pollution in photo's of the current night sky.
LOTOS-EUROS is a computer model to predict ozone, particulate matter and aerosols for the bottom layer of the atmosphere. It is used for the daily predictions of air quality, among many other applications. The main part of the code was already parallelized. Yet, when asked by KNMI to look into the code, VORtech managed to increase the performance by another 30%.
Optimizing an investment portfolio
Asset management companies often have an annual procedure to determine the investments that will be done to keep the assets in good shape. There are always more investment proposals than the budget allows. Making a good choice of proposals is challenging.
The WaterCorrelator is an innovative software tool for improved water management, leveraging hidden information obtained from available data.
