Structure in social networks

To find the network communities, we need a mathematical equation that describes when a division of the network into communities meets these two criteria.

Dispatching experts to do maintenance

Using data analytic techniques and Artificial Intelligence you can analyse data from hospitals and discover hidden patterns that allow us to often predict (within a margin of accuracy) failures before they happen. When a failure is predicted, we issue an alert and we plan for preventive maintenance by an expert engineer.

From Tweets to Communication Networks

Network visualizations have the power to display how we communicate with each other in social media. We can simply depict message exchanges using communication networks. In such a network, nodes represent users, and there exists an edge between two nodes when the corresponding users exchange information (an email or a tweet).

The travelling salesman problem

Suppose you have a delivery service. You have one truck and have to deliver a large number of parcels to different cities in the country every day. Then you run into the following problem: in which order should you visit the cities?

Poster Women in Mathematics

EWM-NL has prepared a poster about women in mathematics, inspired by a poster on Notable Women in Computing. In this article you can find the beautiful poster, prepared by a joint Dutch and UK team comprising Maria Vlasiou and Silvy Hendriks (NL), and Houry Melkonian.

DNA self-assembly gives birth to new mathematics

At this very moment, the emergent science of DNA self-assembly is giving birth to a new field of mathematics that might be called DNA-mathematics. Cleverly constructed DNA molecules will self-assemble into pre-determined complex structures when placed in solution together. 

Not all jet-lags are the same

The part of the brain that controls the sleeping cycle is made up of two groups of neurons. In order for you to be able to sleep at night, the activity of these neurons needs to be synchronized with the cycle of the sun (e.g. active during the day and inactive at night). When you abruptly change the cycle of the sun (by flying to New York) these two groups need to re-synchronize to the new sun-cycle.

How parallel computing can be (in)efficient

Today, we demand much more from our devices and we take for granted that they all work nice and fast. Without realizing, we usually greatly value a speedy processing of our tasks. Speed is thus of the essence, but how do current-day devices cope with this? The answer: your devices can multi-task.
