Swedish patent nr 189939. "Anordning för alstring av ett artificiellt tröghetsmoment hos ett roterbart anordnat system". (Device for creating an artificial moment of inertia in a rotating system.) Co-inventor Folke Hector Philips. Granted January 16 1964. Patent also granted in England, France, Holland, Canada, Germany, USA, Austria, Japan. This patent describes a new way of implementing Schuler

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

Fluorescence spectroscopy in two different biomedical applications have been studied. One field has been to explore whether fluorescence spectroscopy can be used to determine the depth of a fluorescent object inside a tissue-like medium. Recorded fluorescence spectra depend on the localisation of the fluorescent inclusion and may provide additional information for optical tomography. The second ma

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.

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

The extinction paradox states that a perfectly electric conducting target which is large compared to the wavelength removes from the incident radiation exactly twice the amount of power it can intercept by its geometrical cross section area. In this paper, the extinction paradox is generalized to include temporally dispersive material parameters with finite values of the permittivity and the perme

The high Q-factor (low bandwidth) and low efficiency make the design of small antennas challenging. Here, convex optimization is used to determine current distributions that give upper bounds on the antenna performance. Optimization formulations for maximal gain Q-factor quotient, minimal Q-factor for superdirectivity, and minimum Q for given far-field are presented. The effects of antennas embedd
