This paper deals with Epi.q, a family of mobile robots whose main characteristic is a wheel-legged hybrid locomotion. These multi-purpose robots can be successfully exploited for security and surveillance tasks. The document presents state of the art security robotics, the Epi.q mechanical architecture, the concept behind the robot driving unit, three prototypes and the design of a new one.

Most applications of land cover maps that have been derived from satellite data over the Arctic require higher thematic detail than available in current global maps. A range of application studies has been reviewed, including up-scaling of carbon fluxes and pools, permafrost feature mapping and transition monitoring. Early land cover mapping studies were driven by the demand to characterize wil...

In this paper, we investigate whether a dataset derived from a multi-purpose corpus such as the Spoken Dutch Corpus may be considered appropriate for developing a taxonomy of wh-questions, and a model of the way in which these questions are integrated in spoken discourse. We compare the results obtained from the Spoken Dutch Corpus with a similar analysis of a large random collection of FAQs fr...

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....
