Benchmarking Distributed Stream Data Processing Systems

The need for scalable and efficient stream analysis has led to the development of many open-source streaming data processing systems (SDPSs) with highly diverging capabilities and performance characteristics. While first initiatives try to compare the systems for simple workloads, there is a clear gap of detailed analyses of the systems'...

Changing behaviour: A European action research project

CHANGING BEHAVIOUR is a project that aims to support change in energy use and energy services. We do so by applying social research on technological change to practical use. Our focus is on the interaction between energy experts and energy users: How can these different groups learn to understand each other better? Another focus is the role of...

Learning about users and developing co-design capabilities for energy saving on the local level

European energy policy aims to shift the European energy market toward an increased focus on energy services based on end-user needs. This requires a close understanding of the role of end-users and their needs and practices. Our paper is based on a EU FP7 project called CHANGING BEHAVIOUR and focuses on interaction between energy users and...
