Thesis or project ideas from my research
Send me mail if you are interested in a certain topic.
Currently, a group at HdM is building a universal sensor unit. Several sensors can be installed to collect data on NO2, CO2, noise, temparature, location, other chemicals etc. In the simplest version you need to come by with a smartphone to unload the data into a cloud service. If more energy is available, the unit can push data by itself into the cloud via Wifi or GSM. All sensors should have us USB connector. The unit can be used to measure fine dust particles also, using a sensor from Stuttgart.
The paper on time in VMWare VMs made me kind of skeptical about the performance of distributed algorithms (e.g. failuer detection) in settings with instable time. The thesis would set up some VMs and test timing behavior of distributed algorithms for consensus or failure detection. Will jumps in time only affect liveness or even consistency?
Using bots to collect data from social networks, e.g. to investigate the creation and spreading of fake news.
How to simulate distributed algorithms and their failure models to get a handle on complex protocols like Paxos. Or how to simulate a large scale site using components.
Social GUI construction and application integration for large-scale multi-touch installations. Social analysis of interaction patterns, technical design and implementation. The scale of those devices makes single user concepts useless and requires group interfaces.
This has been a sore spot for quite a while: to enable discussions at events it is necessary that everybody has access to a microphone (this is also needed for streaming). Unfortunately the way this is done till now is through the use of long poles with microphones held by helpers into the public, by stationary microphones hanging from the ceiling in large numbers or by speakers leaving their seat and walking over to fixed microphones. This is all either too expensive or too clumsy given out narrow rows of seats and the need to hold events in different rooms each time.
My idea involved throwable microphones which can be centrally controlled and which are activated by pressing the ball. Most discussions involve only very few people and locations within a larger room and a small number of these ball-mics would be distributed across the room. Speakers can get access quickly. The following drawings might give you an idea: and a version that uses balloons hanging from the ceiling:
The article "the problem of many speakers" gives an explanation of the context.
