Crossing the bottleneck of rain formation [article]

Martin Rohloff, Tobias Lapp, Jürgen Vollmer
2014 arXiv   pre-print
His derivation does not provide a physical interpretation of the values of α, and was criticised in Rohloff et al.

OpenWHO: Integrating Online Knowledge Transfer into Health Emergency Response

Tobias Rohloff, Heini Utunen, Jan Renz, Yu Zhao, Gaya Gamhewage, Christoph Meinel
2018 European Conference on Technology Enhanced Learning  
The platform OpenWHO was developed in 2017 in a cooperation between the World Health Organization (WHO) and the Hasso Plattner Institute (HPI). The Department of Infectious Hazard Management, under the WHO Health Emergencies Programme, worked together with the HPI to create a new interactive, web-based, knowledge-transfer platform offering online courses to improve the response to health emergencies. The platform was newly launched as there was an identified need of an open and scalable
more » ... for fast distribution of life-saving content in disease outbreaks for frontline responders. The platform provides adjusted versions of the massive open online learning resources that are self-paced and at ease formats for the frontline and low-bandwidth use. The HPI already developed know-how in previous Massive Open Online Course (MOOC) projects like openHPI and openSAP. OpenWHO is based on the same technology as the aforementioned projects. This paper will provide insights into the practical deployment, the adaption of the MOOC concept, and lessons learnt within the first year of this platform.

Recognizing Compound Events in Spatio-Temporal Football Data

Keven Richly, Tobias Rohloff, Max Bothe, Christian Schwarz
2016 Proceedings of the International Conference on Internet of Things and Big Data  
In the world of football, performance analytics about a player's skill level and the overall tactics of a match are supportive for the success of a team. These analytics are based on positional data on the one hand and events about the game on the other hand. The positional data of the ball and players is tracked automatically by cameras or via sensors. However, the events are still captured manually by human, which is time-consuming and error-prone. Therefore, this paper introduces an approach
more » ... to detect events based on the positional data of football matches. We trained and aggregated the machine learning algorithms Support Vector Machine, K-Nearest Neighbors and Random Forest, based on features, which were calculated on base of the positional data. We evaluated the quality of our approach by comparing the recall and precision of the results. This allows an assessment of how event detection in football matches can be improved by automating this process based on spatio-temporal data. We discovered, that it is possible to detect football events from positional data. Nevertheless, the choice of a specific algorithm has a strong influence on the quality of the predicted results.
