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

Popular Abstract in Swedish Denna avhandling berör metoder för hur beräkningsmekaniken kan förbättras med avseende på förbättrad och effektiv användning av verktyg och resurser. Den berör också ideér för hur verktyg i beräkningsmekanik skall kunna tillämpas i områden där dessa ej tidigare använts. Tre huvudområden har studerats: Effektiv och transparent tillgång till finita element applikationer, This work concern ideas and methods on how the context of computational mechanics can be improved for more efficient utilisation and extended into areas previously not familiar with or capable of using such tools. Three main areas were studied: Providing efficient and transparent access to finite element applications, development of methods for the visualisation of complex phenomena and improving

Popular Abstract in Swedish Avhandlingens syfte var att utveckla en checklista för bedömning av utemiljön i flerfamiljs bostadsområden. Fem experter inom arkitektur, landskapsarkitektur och stadsplanering medverkade i den första utvärderingen som omfattade sex bostadsområden i Lund. Utfallet validerades genom jämförelse med de boendes egna värderingar. Denna omfattade mer än 400 personer och analyThe primary goal of this thesis was to develop an Expert checklist for assessing and de-veloping outdoor residential environments. The checklist was utilized by 5 experts in the fields of architecture, landscape architecture, and urban planning who were all fa-miliar with the concept of architectural psychology. The checklist was validated against a Post-occupancy evaluations form (POE) that was d

We propose a technique for test scheduling and design of test bus infrastructure where test application time and test bus length and width are minimized while constraints on power consumption and test resources are considered. Our approach is suitable for repeated use in the design space exploration process due to its low computational cost. For the final design, we use simulated annealing to opti

A collection of original chapters focusing on young people and their political involvement, their use of the internet and other new media for learning the roles and practices of various forms ofcitizenship. The collection is analytically framed by the current dilemmas of democracy

In the autumn of 2011, the course “The City: Boundary Transgressions and Visual Expressions” was given for the first time. Formally placed at the Division of Art History and Visual Studies, the course is a collaboration with the Division of Social Anthropology and is directed towards students from a range of disciplines within the fields of the humanities and social sciences. The course includes

Sustainability has been on the agenda for decades. Yet it is not evident that the development we are witnessing can qualify as sustainable. Departing from an understanding of the adoption of sustainability as an on-going, unfinished process the thesis explores conditions for sustainability in Swedish transport infrastructure policy and planning. The study covers decision processes of three mega-pr

Biogas, a mixture of methane and carbon dioxide, is produced by microorganisms upon degradation of organic matter in an anaerobic environment. It has been realised that by utilising anaerobic processes the organic pollutants in wastewater and organic solid waste from anthropogenic sources can be converted into a renewable source of energy. However, to fulfil the potential of anaerobic digestion in

The studies in this thesis have shown that the partitioning of endoglucanase I (EGI, Cel7B) from T. reesei could be significantly improved by relatively minor genetic engineering. By adding short peptides composed of tryptophan and proline residues to EGI, extreme partitioning could be obtained. The site of the tag fusion was shown to be crucial for the efficiency of the tag. Methods suitable for

A full-scale in-line primary sludge hydrolysis experiment was conducted in one out of four primary settlers at the Klagshamn Wastewater Treatment Plant (WWTP) to test if the wastewater quality can be improved in terms of providing easily accessible carbon for possible pre-denitrification and the reduction of external carbon sources. The amount of easily accessible carbon produced, in the form of t

Faster-than-Nyquist (FTN) signaling is a trellis coding method that maintains the error rate while reducing signal bandwidth. The combined effect is to move closer to capacity. We study some basic receiver issues: How to model the signaling efficiently in discrete time, how much the Viterbi receiver can be truncated, and how to combine the method with an outer code. The methods are modeling for mi

Affordable and competitive industrial automation is of key importance for small and medium enterprises, in Europe and elsewhere. A key factor is the introduction of new robot automation concepts that ease fast deployment and extend available task repertoire. The Gantry-Tau manipulator is a new robot concept. In contrast to other parallel kinematic manipulators (PKMs), it has a large working range.

Urbanisation has burdened cities with many problems associated with growth and the physical environment. Some of the urban locations in India are becoming increasingly vulnerable to natural hazards related to precipitation and flooding. Thus it becomes increasingly important to study the characteristics of these events and their physical explanation. This work studies rainfall trends in Delhi and
