A digital twin for the indoor climate in data centers

4DCOOL is a digital twin for the indoor climate in the server rooms of data centers. It provides an actual and accurate 3D view of the temperature and flow. In addition 4DCOOL allows operators to run what-if scenarios. This lets them play with settings for the cooling so as to minimize costs and avoid local hot spots.

Speedup of software for assessing flood defenses

Every 12 years, the Dutch Department of Water Ways and Public Works assesses the strenght of the flood defenses, using the Hydra Ring software. VORtech realised a significant speedup of the software, using both code optimisations and algorithmic improvements.

Insights for Water Boards

Water managers in the Netherlands are responsible for an extremely complex water system, where the impact of actions is not always obvious. Therefore water managers need more insight into the relations between variables in their system.

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.

Sewer monitoring

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.

Extending IMAGE

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.

SIMONA maintenance

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.

Analysis of turn-out times

VORtech analysed data about turn-out times for fire departments. Understanding the characteristics of these turn-out times allows for optimization of various internal processes.

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 Optimization

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.

Avoiding unsuccessful Home Visits

VORtech analyzed a data set about service men calling on customers who ware not at home. The number of such unsuccessful home visits can be reduced significantly by exploiting patterns in the probability that people in a certain area are at home.

Travel Times for Inland Shipping

For the Dutch start-up 4Shipping, VORtech, together with other partners, developed a tool to predict travel times for inland shipping. The time spent on waiting for ship locks is an important aspect.
