In the RUNES project a disaster relief tunnel scenario is being developed in which mobile robots are used to restore the radio network connectivity in a stationary sensor network. A component-based software development approach has been adopted. Two components are described in this paper. A localization component that uses ultrasound and dead reckoning to decide the robot positions and a collision
This paper presents an evaluation of single input single output (SISO), single input multiple output (SIMO) and multiple input multiple output (MIMO) channel capacities for a dual antenna prototype in proximity of a user. The dual antenna prototype mimics today’s small mobile phone design in size and in comprising internal, compact, multi-band antennas. Four different user cases are evaluated by m
One of the latest additions in defining the test process is the upcoming ISO/IEC 29119 standard, which aims to define a universally applicable generic test process model. However, currently the standard does not offer any support for the adoption process of the model. In this paper, we present our framework, which aims to combine a maturity level-based approach with the standard process. Our objec
An overview of Grafchart, a graphical language for sequential control applications is given. Grafchart is based on Grafcet/SFC to which it adds concepts from High-level Petri nets, Statecharts and object-oriented programming. Applications of Grafchart in batch control, alarm filtering, decision support, and FMS are briefly presented.
This paper discusses the prospect of a sociology of science informed by the critical realist philosophy of science. The discussion departs from the need for a theoretical framework to account for theoretical struggle and reproduction in the field of econom-ics. The recent talk about an ontological turn in science studies and the wider back-ground for such a turn is then related to the earlier turn
A fundamental problem in vision is how to identify the occluding contours of objects and surfaces, given the ambiguity inherent in low-level visual input. A computational model is proposed for how occluding contours could be identified by making use of simple heuristics that reduce the ambiguity of individual features. In the striate cortex, a large majority of cells are selective for both contras
Coordination is an important success factor for a development project. Communication gaps, e.g. between product owners shaping the requirements and testers verifying the developed software can result in wasted effort and unsuccessful products. We propose improving the communication between project members with recommendations of whom to interact with and what to discuss based on link prediction in
