Sebastiaan Griffioen: Extracting travel information from GSM data
What kind of information can be extracted from the GSM network data received by a cell phone during a train travel? This paper describes the research that resulted in a cell phone application based on monitoring and logging the sequence of network connections and changes of signal strength in relation to time. The obtained data is analyzed using an offline and a realtime model. Tests of both models on different trajectories are showing reliable results.

Eric Kuijl: Activities of online predators on Social Networking Sites
Criminals found their way to new technologies on the internet in many different ways. In this paper we investigate the presence of online predators on social networking sites and how these predators can be recognized. We conclude that online predators are indeed active on social networking sites, however recognizing and automatically detecting them is complex. Nevertheless, to make it easier to detect and investigate online predators, we describe methodologies and properties of online predators. In combination with specially built monitoring software using these properties, it is possible for the police to monitor online predators known from offences committed in the past.

Joris Slob: The Human Processor: how humans can be used as an ALU without being aware of this fact
We explored the feasibility of creating an Arithmetic Logic Unit (ALU), the core component of any processor, using human actions instead of electronic components. In our setup we tested if humans were aware of the fact that they were functioning as a crucial computer component. Multiple setups were presented and one setup was tested. This setup used the color perception faculty of humans to perform the necessary logic to implement an ALU. The test showed that the subjects were unaware of the fact they were part of a calculation. Because of the simplicity of the task the subjects underestimated the number of operations they preformed.
This novel implementation of an ALU has interesting properties: humans are fallible and as a result calculations made on this architecture may be incorrect.
In the presentation this project is described and placed in an historical context of computing, in particular the field of unconventional computing. Please bring humans along, we need them to run our computer(s).
