Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissio
The concept of this research is that by applying the proposed method, the trajectory of drift into failure can be made visible. The method itself consists of two sequential steps. For research purposes a third step is added. The first step is constructing a phased narrative, consisting of all the changes that have taken place within a particular organisational process subject to research. What has
This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13.7 keV, generated by the synchrotron radiation, impinges the material, and fluorescent X-ray spectra
Fracture risk in osteoporosis is increased and osteoporosis is the most common metabolic bone disease and treatment is expensive. Osteoporosis is diagnosed by measuring Bone Mineral Density (BMD), which does not consider other factors such as bone geometry or architecture. 3D-based models can predict risk fracture better than BMD, but they require 3D computed tomography. Solution of the problem is
Determining how proteins interact with each other to form complexes is very important for understanding both disease and cellular functions, but experimentally determining the structures of these complexes is both tedious and slow, which is why a great number of protein-protein docking algorithms have been developed to predict them. To this day, conformational changes in protein backbones have bee
This project entails the development of a model for determining the spatial resolution in scanning applications of pulsed-neutron sources, such as at the European Spallation Source (ESS). The development of this model involves the simplification of the problem of representing a pulse neutron scanning across a sample by approximating the pulsed neutron beam as a continuous laser beam scanning acros
Increasing global temperatures have been shown to advance the breeding phenology of migratory birds, not least in temperate regions, causing birds to adapt the timing of other life-history events such as molt. At high latitudes, summers are shorter, and the birds must complete their post-breeding molt in the few weeks available before the conditions in the breeding site become unfavorable. I exami
Animal migration is a widespread phenomenon that has evolved repeatedly in a diverse set of taxa. To cope with migration, individuals express a large variety of specialized behavioural adaptations, that rely on efficient sensory systems for extraction of relevant external information. Many behaviours are visually guided, such as foraging and predator avoidance, and most migratory animals possess e
Vägarna i Sverige är totalt cirka 57 000 mil långa. Av dessa anses cirka 43 000 mil vara tillhöriga enskilda väghållare, det vill säga någon annan än offentliga aktörer så som stat eller myndighet. Vägar har länge haft en stor betydelse ur ett flertal aspekter och det har alltid funnits ett stort intresse av att vidhålla ett gott infrastruktursystem. Bestämmelser om vägar fanns det redan i de äldThe aim of this paper is to improve the management of joint facilities and private roads. This was done by identify and investigat different problems connected to the private road organisations, formed through the regulation of joint facility and associations connected to them. One aspect of the investigation was if the area of included land connected to one joint facility had grown in size. By st
Bakgrund: Med anledning av Barnkonventionens inkorporering i svensk lag är det idag högst aktuellt att undersöka och diskutera hur barn upplever att de ges möjlighet att vara delaktiga i sin vård. Barns delaktighet bygger på en god kommunikation och relation till hälso- och sjukvårdspersonal. Trots föreskrifter om att barn bör vårdas på avdelningar avsedda och anpassade till dem, förekommer det re
Den här studien undersöker en grupp musikelevers improvisatoriska val över dominantackord som leder till tonika i improvisationer över II V I-progressioner i dur. Studiens fokusområde motiveras av den höga andel II V I-progressioner som används som musikaliska byggstenar i genrer där improvisation förekommer i hög grad. Även om det inte ligger inom räckhåll för den här studien att undersöka kausalThis study focuses on a group of music students’ improvisational choices over the Vchord leading to the I-chord when improvising over major II V I chord progressions. The raison d'etre for this study is the high number of II V I-progressions being used as musical building blocks in genres that have improvisation as an integral part. Although it was not within the scope of this study to establi
Bakgrund: Människors livsstil och hälsa innan befruktning kan påverka graviditet, barnafödande och fostrets utveckling och välmående varför prekonceptionell hälsa och vård är viktig för alla individer. Barnmorskan arbetar med reproduktiv, perinatal och sexuell hälsa men möter sällan pojkar och unga män i sitt arbete. Skolsköterskan har därför föreslagits som lämplig att informera pojkar och unga m
Rapidly changing environments across the globe pose challenges for organisms to either adapt or risk extinction. High rates of gene flow are expected to prevent populations from adapting to their local ecological environments, but an increasing number of studies show that even at small geographical scales, natural or sexual selection can counteract the homogenizing effect of gene flow. Here I show
Over the last century, Swedish forests have undergone rapid land-use change due to intensification of management practices for timber production and the introduction of monocultures, which have resulted in considerable habitat loss and negative impacts to biodiversity. Insects form a significant component of forest biodiversity, yet forest-dwelling pollinators remain understudied, and little is kn
I Europaparlamentets och rådets förordning 2018/844, sätter EU krav på sina medlemsländer att skapa strategier för att uppnå energieffektivisering i byggnads-sektorn för att nå de mål som satts upp av FN i Parisavtalet. En stor del av byggnadsbeståndet utgörs av äldre byggnader och dessa byggnader har ofta allt för höga energibehov. För att arbeta mot FN:s mål, finns det ett stort behov av energi-The purpose of this master thesis was to examine what kind of energy efficiency measures that could be applied on older buildings and whether they could be profitable investments. In order to be able to calculate the relative energy saving effect of the measures, a specific building has been chosen, located in Malmö, southern Sweden and was built in the 1880. Different kind of energy efficiency
