Kalamov, Zarko (2020-01-21)

We analyze how a sales tax levied on all food products impacts the consumption of healthy food, unhealthy food, and obesity. The sales tax can stimulate the consumption of healthy meals by lowering the time costs of food preparation. Moreover, the sales tax lowers obesity under more general conditions than a tax on unhealthy food (fat tax) and a subsidy on healthy food (thin subsidy). We calibr...

Employing Environmental Data and Machine Learning to Improve Mobile Health Receptivity

Theilig, Max-Marcel ; Korbel, Jakob J. ; Mayer, Gwendolyn ; Hoffmann, Christian ; Zarnekow, Rüdiger (2019-12-09)

Behavioral intervention strategies can be enhanced by recognizing human activities using eHealth technologies. As we find after a thorough literature review, activity spotting and added insights may be used to detect daily routines inferring receptivity for mobile notifications similar to just-in-time support. Towards this end, this work develops a model, using machine learning, to analyze the ...

As of today, emergency services are often unable to arrive at the victim in time, and laypeople on the scene frequently fail to c...

Implikationen der Integration von Energiespeichern in Stromnetze am Beispiel des deutschen Stromversorgungssystems

Witkowski, Adam (2019)

Auf dem Hintergrund der Energiewende führt der rasante Ausbau erneuerbarer Energien – allen voran Windkraftanlagen und Photovoltaiksysteme – zu höheren Strommengen aus fluktuierenden Energiequellen in Stromversorgungssystemen. Insbesondere in Deutschland führt deren hoher Anteil zu Integrationsschwierigkeiten, die sich u.a. in zeitweise negativen Strompreisen ausdrücken. Die Bundesregierung sie...
