This paper introduces the idea that location based pervasive games can be used to make mobility training for visually impaired children more fun. The user centred development process which has been carried out in collaboration with both visually impaired children and rehabilitation staff is described and we present a novel game concept which combines locative play, sound traces and a physical catc
he surface structure of Bi(110) has been investigated by low-energy electron diffraction (LEED) intensity analysis and by first-principles calculations. Diffraction patterns at a sample temperature of 110 K and normal incidence reveal a bulk truncated (1×1) surface without indication of any structural reconstruction despite the presence of dangling bonds on the surface layer. Good agreement is obt
Abstract in UndeterminedCompanies in the food industry are driven to improve their traceability for several reasons. The primary reasons are food safety and quality. Another is the response to the increased interest among consumers in imperceptible product attributes such as organic, fair trade, dolphin-safe and non genetically modified (non-GMO). Such attributes are hard to distinguish and thus r
Computers are increasingly used for implementing controlalgorithms in safety-critical embedded applications, such asengine control, braking control and flight surfacecontrol. Addressing the consequent coupling of control performancewith computer related errors, this paper develops a composite computerdependability/control theory methodology for analyzing the effectsdata errors have on control syst
The objective of this study has been to create an online system for condition monitoring and diagnosis for a combined heat- and power plant in Sweden. This system consists of artificial neural network models, representing each main component of the combined heat- and power plant, accompanied with a graphical user interface. The artificial neural network models are integrated on a power generation
The new challenge of the Gas Turbine industry is to develop new technologies for meeting electricity demand growth and reducing harmful emissions. Thus a better understanding of the combustion phenomenon and an improvement in simulation capabilities are needed. Large Eddy Simulation tools brought the hope of meeting these two conditions and enabling the design of safe and clean burners. In the pre
We report on a theoretical study of the quantum interference behaviour of electron flow from a double-slit device made from a semiconductor two-dimensional electron gas (2DEG) system with the slit widths in the quantum conductance regime. The device consists of a double slit and a single slit in a configuration where the single slit is placed on the source side of the double slit. The wavefunction
The thesis investigates elite children’s lives in China between 500 and 1000 ACE within the framework of historical anthropology. Based on ‘anomaly accounts’ (collected in the Taiping guangji), medical manuscripts, family instructions, ‘children’s books’, tomb inscriptions, official histories, law and tax code, and poetry, this thesis provides a general definition of childhood and children in medi
Background: Comorbidity amongst anxiety disorders is very common in children as in adults and leads to considerable distress and impairment, yet is poorly understood. Multivariate genetic analyses can shed light on the origins of this comorbidity by revealing whether genetic or environmental risks for one disorder also influence another. We examined the genetic and environmental influences on the
An interview study was performed in order to reveal some of the problems associated with evacuation of a train inside a tunnel for senior citizens and people with disabilities, and to identify possible technical installations that would aid their evacuation. A total of 19 people took part in the study, in which it was demonstrated that senior citizens and people with disabilities require either a
Bodnar and Schmid (2008) derived the distribution of the global minimum variance portfolio weights and obtained the distribution of the test statistics for the general linear hypothesis. Their results are obtained in the case when the number of observations n is bigger or equal than the size of portfolio k. In the present paper, we extend the result by analyzing the portfolio weights in a small sa
