March Talks Now on YouTube

Monday, April 6, 2015

Paul Mueller, Florian Michahelles, and Oliver Kramer

In March, we were honored to host three speakers, including an alumnus of our visiting program. Oliver Kramer, now a juniorprofessor at the University of Oldenburg, Germany, was a postdoc sponsored by the German Academic Exchange Service, or DAAD, in 2011.

Florian Michahelles of Siemens gave the first talk in a new series, the Rubric, that features our senior researchers.

And Professor Paul Müller of the University of Kaiserslautern dropped by to speak about his institution's virtual laboratory for distributed systems research.

All three talks are now available through our YouTube channel. Check them out there or below.



Uncharted Lecture Series: A Framework for Data Mining in Wind Power Time Series

Oliver Kramer
University of Oldenburg


Wind energy is playing an increasingly important part for ecologically friendly power supply. The fast growing infrastructure of wind turbines can be seen as a large sensor system that screens the wind energy at a high temporal and spatial resolution. The resulting databases consist of huge amounts of wind energy time series data that can be used for prediction, controlling, and planning purposes. In this talk, I describe WindML, a Python-based framework for wind energy related machine learning approaches. The main objective of WindML is the continuous development of tools that address important challenges induced by the growing wind energy information infrastructures. Various examples that demonstrate typical use cases are introduced and related research questions are discussed. The different modules of WindML reach from standard machine learning algorithms to advanced techniques for handling missing data and monitoring high-dimensional time series.




The Rubric Lecture Series: From the Internet of Things to a Web of Systems
Florian Michahelles


Ubiquity of connectivity has let the Internet grow out of a network of computers to an Internet of Things. The idea of collecting data from physical things and taking triggering actions in the real world has also started influencing the thinking of how to organize processes in industry. This talk will reflect on the problems and challenges to be solved in various industries domains and discuss the approach of applying semantic technologies in order to add machine-readable meaning to domain-specific industry knowledge. This talk will describe what Siemens has coined as Web of Systems and list corresponding research questions.

A Virtual Laboratory for Distributed Systems Research: ToMaTo Topology Management Tool

Paul Müller
University of Kaiserslautern


Networking research and development is an important field in information technology and its importance grows with the rise of the Internet and the ubiquity of worldwide communication. Besides theoretic analysis and simulation, testbeds are a key tool for research and development in this area. In the German-Lab project, a national Future Internet research project that combines both, research and experimentation, a flexible testbed has been developed. A part of the facility is the topology management tool (ToMaTo), a topology centric networking testbed. Currently ToMaTo has been deployed to over 120 nodes worldwide and has been successfully used in research as well as in education. ToMaTo has been designed to be an easy to use, flexible and resource efficient testbed for network research within virtual topologies. This presentation will show the concepts of G-Lab especially the Topology Management Tool and its applications in research and education. Moreover a short overview of a new project “Testbed on Demand” based on the NSF funded CloudLab infrastructure is given.
