Cars in Transition - An Assessment of Future Vehicle Technologies

The transport sector is facing serious challenges in meeting long-term sustainability criteria. Radical changes in the design of vehicles to attain competitive vehicles with substantially better environmental performance will probably constitute an important part in a future sustainable transport sector. The aim of the study described in this thesis is to assess the long-term options currently und

Tracking and Reconstruction of Vehicles for Accurate Position Estimation

To improve traffic safety it is important to evaluate the safety of roads and intersections. Today this requires a large amount of manual labor so an automated system using cameras would be very beneficial. We focus on the geometric part of the problem, that is, how to get accurate three-dimensional data from images of a road or an intersection. This is essential in order to correctly identify dif

Survey on Safety Evidence Change Impact Analysis in Practice: Detailed Description and Analysis

Critical systems must comply with safety standards in many application domains. This involves gathering safety evidence in the form of artefacts such as safety analyses, system specifications, and testing results. These artefacts can evolve during a system’s lifecycle, and impact analysis might be necessary to guarantee that system safety and compliance are not jeopardised. Although extensive rese

Numerical study of thermo-acoustic waves generation by a swirling flame using a new approach based on large eddy simulation

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. In this paper, we present a new technique that is computationally efficient, for capturing the thermo-acoustic waves in low Mach number c

Europeiska möten med historien : historiekulturella perspektiv på andra världskriget, förintelsen och den kommunistiska terrorn

1990-91 drogs nya gränser i Europa. Inte bara kartan ritades om. Också historien har förändrats när 1900-talets avgörande händelser, andra världskriget, förintelsen och kommunistterrorn, tagits i bruk för att skapa ett nytt Europa. Det är visserligen en process som pågått under hela efterkrigstiden, i den tyska skuldbearbetningen, debatten om det totalitära samhället, det ökade intresset för förin

The linguistic encoding of placement and removal events in Jahai

This paper explores the linguistic encoding of placement and removal events in Jahai (Austroasiatic, Malay Peninsula) on the basis of descriptions from a video elicitation task. It outlines the structural characteristics of the descriptions and isolates semantically a set of situation types that find expression in lexical opposites: (1) putting/taking, (2) inserting/extracting, (3) dressing/undres

Geometry of meaning : semantics based on conceptual spaces

In The Geometry of Meaning, Peter Gärdenfors proposes a theory of semantics that bridges cognitive science and linguistics and shows how theories of cognitive processes, in particular concept formation, can be exploited in a general semantic model. He argues that our minds organize the information involved in communicative acts in a format that can be modeled in geometric or topological terms—in w
