From manual to automatic pavement distress detection and classification

Detection and classification of distresses is a fundamental activity in the road pavement management. Even in the early stages of deterioration, road pavement needs to be monitored to identify problems, evaluating the actual conditions and predicting what the future conditions will be. Monitoring activities through manual/visual inspections are time consuming, costly and cause of safety concerns.

Comparative studies of cognitive abilities in the Paridae : Evidence from laboratory studies

Många beteenden hos djur kan vara oflexibla och mer eller mindre ”hard-wired” i hjärnan. Sådana beteenden kan vara ändamålsenliga för regelbundna och rytmiska förändringar i naturen, såsom dag och natt, årstider, etc. Men många faktorer är naturligtvis oförutsägbara i naturen. För sådana oförutsägbara förändringar är det bättre för djur att vara flexibla i sitt beteende. Kognition är en process soThe Paridae (tits, titmice and chickadees) is a bird family consisting of both food hoarding and non-hoarding species. Many studies have been conducted on birds that are considered to be cognitively advanced, such as parrots and corvids, whereas much less is known about these small passerines. In this thesis, I have investigated the cognitive abilities of two members of the Paridae family; marsh t

Self-Assembly in Lipid-Protein Systems : Lung Surfactant, Stratum Corneum and Model Membranes

Den yttersta barriären mellan luften och blodomloppet i våra lungor består av en lipid-protein film. Denna lipid-protein blandning kallas för lungsurfaktant. Filmen bestående av lungsurfaktant stabiliserar alveolerna i våra lungor och gör att vi kan andas utan motstånd. Brist av lungsurfaktant kan orsaka svåra sjukdomar, till exempel hos förtidigt födda barn som ännu inte hunnit bilda tillräckligtThis thesis explores lipid self-assembly and aims to give a broad picture of self-assembly structures in simple and complex lipid-protein systems. The systems studied are lung surfactant, stratum corneum and simple model membranes. The lung surfactant mixture lines the alveolus in our lungs and stabilises the air- tissue interface. The lung surfactant lipid phase behaviour was here investigated wi

The system consists of the magnetic spectrometer SPES4 and two wide-aperture position-sensitive detector arr

Grasping complexity: analysing risk for sustainable development

Popular Abstract in Swedish Hållbar utveckling ställer krav på nya riskanalysmetoder Hållbar utveckling bygger på vår förmåga att fatta beslut i dag som avgör vår morgondag. Det låter enkelt, men är en av mänsklighetens största utmaningar då mycket i vår värld hänger samman och framtiden är full av osäkerheter. Givet att osäkerhet tillåts påverka vår syn på vad framtiden har i sitt sköte, kan dSustainable development relies on our ability to make decisions today that will determine our tomorrow. Given that uncertainty is explicitly allowed to influence our view of what the future holds for us, most ex ante analyses of challenges for sustainable development can be viewed as analysing risk. Many frameworks for analysing risk exist today, but analysing risk for sustainable development enta

Drop Break-up in High-Pressure Homogenisers

Popular Abstract in Swedish Den här avhandlingen behandlar hur fettdroppar i mjölk slås sönder i en mjölkhomogenisator. Mekanismerna bakom sönderslagningen har analyserats genom uppmätning av flödesfältet i spalten samt genom att fotografera dropparna, när de slås sönder. För att möjliggöra mätning och fotografering har två skalmodeller av en homogenisator tagits fram. En fullskalemodell, vilken The overall aim of this project was to investigate the drop break-up process in milk homogenisers. This was done by measurements and calculations of the flow fields in the gap region and by visualisation of drops being broken up. To make visualisation and measurements possible, two scale models of a homogeniser gap were developed. The full-scale model was a direct copy of the gap in a production-

COMPARISON OF THERMAL HAND MODELS AND MEASUREMENT SYSTEMS

Five sets of gloves were tested on 3 hand models with 2 measuring system in order to ensure repeatability of results from the past and for the future. The other aims of the study were to compare the possible differences related to different number of measuring zones, and effect of temperature distribution over hand surface. The hand models had 2 (HF), 9 (H2) and 10 (H3) zones respectively. Models

Elderly Immigrants, Socio-economic Status and Health. An epidemiological study of cardiovascular risk factors, impaired mobility and self-reported health status.

Popular Abstract in Swedish Under 1990-talet har vi bevittnat flera kriser i hela världen, men mest i Europa, Afrika och Mellanöstern. Det har oftast rört sig om inbördeskrig, men även om naturkatastrofer, fattigdom, samt politisk och/eller religiös förföljelse. Alla dessa faktorer har resulterat i en ökad migration. Enligt Statistiska centralbyrån (SCB) var 11,5 % av Sveriges befolkning utlandsföAims: To analyse the relationship between country of birth/ethnicity, socio-economic status (SES) and impaired mobility, impaired working capacity, cardiovascular disease (CVD) risk factors, health behaviours among those with CVD risk factors, self-reported health status, impaired instrumental activities of daily living (IADL) and all-cause mortality. Methods: Two main data sources were used: the

A psychological process approach to decision making : Post-decision restructuring of value conflicts

Popular Abstract in Swedish Senare forskning har påvisat att beslutsfattare som återger attraktivitets skattningar (aspekter) av egenskaper (attribut) av det valda och det icke valda alternativet i ett beslut som de tidigare fattat, ökar attraktivitets differensen mellan alternativen. Denna efterbesluts attraktivitets differentiering (konsolidering) verkar till fördel för det valda alternativet. KRecent research has shown that when decision makers in retrospect are asked to reproduce attractiveness evaluations (of aspects) of important characteristics (attributes) of a chosen and a non-chosen choice alternative, they exaggerate the attractiveness difference between the alternatives. This post-decision attractiveness differentiation (consolidation) works in favor of the chosen alternative.

En alléodlings inverkan på markfaunan i jordbruksmark

Alléodling – att titta bakåt för att komma framåt Sättet vi odlar på idag är en av de största bidragande orsakerna till de rådande klimatförändringarna. Då ekologiskt jordbruk inte visat sig kunna förhindra denna utveckling tillräckligt och dessutom genererar sämre skördar, är behovet av andra alternativ stort. Många forskare sneglar nu mot metoder som efterliknar traditionellt jordbruk och fördeA transition from conventional to organic agricultural practices has been shown to have positive impacts on soil and ground-living fauna. Organic farming manure is on the other hand harder for the crops to absorb than conventional fertilizers, which results in more pollutants and unsatisfactory yields. This problem is mitigated in alley cropping, an agroforestry practice where rows of trees and bu

Effekten av urbanisering på frösättning av Campanula persicifolia

Stor blåklocka bättre pollinerad i staden än på landsbygden Världen över är människor indirekt beroende av pollinerande djur då de förser oss med mat, mediciner och råmaterial genom att hjälpa växters fortplantning. Inom denna djurgrupp dominerar insekter där bin och humlor är särskilt viktiga på nordliga breddgrader. Det finns dock en stor oro kring våra pollinerande insekter idag. Som ett resul

Surface Plasmon Resonance Nanosensors for the Sensing of Bacterial Threats

Microorganisms have unique biochemical mechanisms to inhibit the growth or kill other microorganisms in the same environment. Bacterial threat agents (BTA) are more effective than conventional weapons because of these characteristics, therefore, the development and production of biological weapons are still relevant. Early warning signals need to be obtained for fast and accurate detection of BTA

From Subsistence to Commercial Producers : Processes of State-led Agrarian Change, Land Tenure Dynamics and Social Differentiation among Smallholders in Ghana.

Agricultural commercialization is concerned with improving market-oriented production in expectation of maximizing profit. While previous state policies in Ghana favoured commercialization by medium and large scale cultivators, there exists a new national commitment dubbed the Planting for Food and Jobs Policy that seeks to leverage on the cumulative productive potential of small farmers for susta

Killer Robots - Autonomous Weapons and Their Compliance with IHL

The pursuit of weapons which distance the soldier from the actual battlefield has been going on ever since the transition from the waging of war using short blades, to the waging of war using bow and arrow. Today, that ambition has reached an almost completion with the ever-increasing number of unmanned, remote-controlled vehicles that are rapidly becoming the most common and prominent method of w
