Robots interacting with other agents in rich information landscapes and complex dynamic physical environments require sophisticated and robust concept and knowledge management capabilities if they are to solve problems, communicate, learn and exhibit intelligent behaviours. In this paper we describe how conceptual spaces provide a powerful substrate upon which to build effective concept and knowle

Infrared excesses associated with debris disk host stars detected so far peak at wavelengths around ~100 μm or shorter. However, 6 out of 31 excess sources studied in the Herschel Open Time Key Programme, DUNES, have been seen to show significant—and in some cases extended—excess emission at 160 μm, which is larger than the 100 μm excess. This excess emission has been attributed to circumstellar d

Issues of sustainable agriculture have much relevance and urgency for the sustainable production of non-eatable products that have an agricultural origin, such as biofuels. In the chapter the opinion is expressed that joint legal regulations on sustainable use of natural resources and sustainable farming methods for eatable and non-eatable products of an agricultural origin can be an efficient sol

Computational methods within structural acoustics, vibration and fluid-structure interaction are powerful tools for investigating acoustic and structural-acoustic problems in many sectors of industry; in the building industry regarding room acoustics, in the car industry and aeronautical industry for optimizing structural components with regard to vibrations characteristics etc. It is on the verge

The present thesis is devoted to the theoretical study of two-dimensional electron systems moving in a modulated lateral periodic potential and a competing perpendicular magnetic field. The three introductory chapters offer a brief exposition of the basic issues in this area -- the description of the electron motion in a prependicular magnetic field, the group of magnetic translations and the comm

Controlled fires are beneficial for the generation of heat and power while uncontrolled fires, like fire incidents and wildfires, are detrimental and can cause enormous material damage and human suffering. Transport phenomena such as buoyant flow, momentum, convective heat and mass transfer as well as chemical reactions between combustible species and oxygen from the surrounding air play important

This explorative study investigated how the participants experienced a VR-presentation of an office building. Three office types (landscape, mixed and traditional) were presented in a between-subjects experimental design to employees at the Ericsson company in Sweden. The effects on the participants’ experience were measured using the Semantic Environ¬mental Scale (the SMB-scale, Küller 1975; 1991
