A tool for optimizing cost and time of a workflow execution with respect to allocation of multi-purpose resources is presented. The optimization is done as a result of simulations, which take into account the cost and time associated with each of the resources, when allocated to transitions in Petri nets representing a workflow. These attributes can be collected and updated based on the logs of...

Vienna University of Technology’s E-Learning Centre introduced Moodle in 2006 as the university’s central learning management system. Custom interfaces to existing IT infrastructure as well as modules developed and deployed according to user’s needs provide for a seamless digital workflow in the university’s teaching, learning and organisational processes. Encouraging the use of the LMS as a mu...

Wireless Sensor Networks (WSNs) are evolving towards interconnected, sensing, processing and actuating infrastructures that are expected to provide services for multiple concurrent applications. In a multi-purpose WSN, concurrently running applications share network resources and each may have varying Quality of Data (QoD) requirements. Our middleware targets these multipurpose WSN deployments....

In this paper, we combine two theories of the dynamics of a large socio-technical system — technology drift and actor-network theory — to address how and why information technologies often need to change, relative to their initial conceptions, during implementation. We analyze the failure of the first introduction of electronic cash in Umeå, Sweden as an example of what happens when drift does ...

The theory of Quantum Chromo Dynamics (QCD) reproduces the strong interaction at distances much shorter than the size of the nucleon. At larger distance scales, the generation of hadron masses and confinement cannot yet be derived from first principles on basis of QCD. The P̄ANDA experiment at FAIR will address the origin of these phenomena in controlled environments. Beams of antiprotons togeth...

In this paper we present AnswerTree, a collaborative mobile location-based educational game designed to teach 8-12 year olds about trees and wildlife within the University of Nottingham campus. The activity is designed around collecting virtual cards (similar in nature to the popular Top Trumps games) containing graphics and information about notable trees. Each player begins by collecting one...

The mining of temporal aspects over multi-dimensional data is increasingly critical for healthcare planning tasks. A healthcare planning task is, in essence, a classification problem over health-related attributes across temporal horizons. The increasingly integration of healthcare data through multi-dimensional structures triggers new opportunities for an adequate long-term planning of resourc...
