The creation of a process model is a process consisting of five distinct phases, i.e., problem understanding, method finding, modeling, reconciliation, and validation. To enable a fine-grained analysis of process model creation based on phases or the development of phase-specific modeling support, an automatic approach to detect phases is needed. W...

Eye Tracking Meets the Process of Process Modeling: A Visual Analytic Approach
Conference Paper

  • Sep 2016
Research on the process of process modeling (PPM) studies how process models are created. It typically uses the logs of the interactions with the modeling tool to assess the modeler's behavior. In this paper we suggest to introduce an additional stream of data (i.e., eye tracking) to improve the analysis of the PPM. We show that, by exploiting this...

Simulation and analysis of the selfish-mining attack on Bitcoin

  • Sep 2016
The aim of this thesis is to consider risk aversion of selfish miners. Risk analysis and the theory of decision processes are introduced. Former work on selfish mining was assuming risk neutral agents. In this paper the model of Eyal and Sirer (2013) is extended to consider the risk behaviour of the agent. Especially the effect of risk aversion is...
