Detektering av sprickor i vägytor med hjälp av Datorseende

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

Sinnesmarknadsföring : En jämförelse mellan två galleriors tillämpning av sinnesmarknadsföring

Purpose: The purpose of this study is to analyze the application of sensory marketing in malls.Problem discussion: The competition between malls is increasing, where visitors are increasing demands on the shopping malls layout. Shopping malls surface and its atmosphere becomes essential in the design of a mall so it will be attractive enough. Sensory marketing can be an appropriate method to stand out from the crowd and attract visitors. Sensory marketing is a process of engaging visitor?s senses to create a strong relationship between the brand and visitors.

Air power och asymmetri ur ett högteknologiskt perspektiv : en fallstudie av Operation Desert Storm, Deliberate/Allied Force och Enduring Freedom

Uppsatsen syftar till att bidra mot ökad förståelse för användandet av Air Power i olika miljöer.Uppsatsen strävar efter att belysa på vilket sätt man har nyttjat högteknologisk Air Power för atterhålla optimalt operativt övertag samt att undersöka vilka risker det eventuellt har inneburit.Detta uppnås genom att studera tre konflikter under 1990-talet och se hur man har använt sig avAir Power och titta på vilken effekt detta har haft. Det primära syftet är alltså att undersöka omhögteknologi är fördelaktigt att använda i olika nivåer av konflikter, eller om avsevärda nackdelarvisar sig.Uppsatsen syfte har också varit att identifiera hur de insatser som genomförts med dominerandeAir Power har påverkat och påverkas av teknologiska utvecklingsskillnader mellan länder.Då all krigskonst handlar om hur man nyttjar sina förutsättningar på bästa sätt blir det logiskasteget att en mindre teknologiskt utvecklad fiende kan göra högteknologisk krigföring ineffektiv.Följande hypotes prövas under arbetet: Högteknologisk Air Power är effektivt även vidasymmetrisk krigföring och vid lågintensiva konflikter.Resultatet ur studien visar att det finns både positiva och negativa effekter. De mest framträdandefördelarna är att teknologin medger flexibelt nyttjande och korta omloppstider, underlättarsamarbete och innebär vidare att ett högt tempo kan hållas genom operationen.Och nackdelarna är att det visar sig vara relativt enkelt att försvara sig under lång tid med småenkla resurser, detta kan visa sig svårhanterat för den politiska nivån. Resultatvärderingen avinsatta medel sker änsålänge alldeles för långsamt.En högteknologisk angripare gör fienden rörligare vilket i längden innebär svårigheter för denegna beslutshanteringen..

Hyllie vattenpark : ett gestaltningsförslag

This project is focusing on a future park that will surround Hyllie water tower in the outskirts of Malmö. The water tower will be located in the central part of the new building area Hyllievång. The park will function as a town park with a special focus on water. The water council of the municipality, Va-verket, has for the last 7 years built up and been in charge for a pedagogical programme in the water tower, were schoolchildren come to learn about the cycle of water and how we use water in our daily life. In the park they want to build a new part that gives experience of water, as a compliment to the information in the tower. What will that park look like, and what shall it be constructed of? How do you bring water to the surface in a park? How can landscape architecture work to enhance the presence of water and make people more interested in water issues? In the search to find the answers to all my questions I have meet with people, read books and visited different places.

En geokemisk kartering över området kring Nasa silvergruva : Effekterna av historisk gruvdrift i svensk fjällmiljö

The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.

Ledarskapsskillnader mellan ofentligt och privat anställda ledare : När sektorstillhörighet inte längre är relevant

The Public vs. private movement has over the past decades identified numerous significant differences between public and private organizations. The observed differences covers almost every field in administrative economics ranging from organizational structure, management accounting, goal-setting and in the past few years even leadership. Strangely, in the majority of these studies little or no regards are given to organizational characteristics or fundamental differences between compared organizations and if these organizations really are comparable when studying the effect of sector.The aim of this study is to compare leadership in relatively similar organizations from both the public and private sector and so clarify if earlier identified differences in leadership styles still surface when leaders working with approximately the same thing in a similar work context are studied.A sample of 348 Swedish principals was drawn from both municipal and private elementary schools. The respondents answered a web-based survey based on the CPE-model resulting in leadership styles mapped according to three orientations: change, production and employee.

Ekonomisk och teknisk uppföljning vid anläggningsprojekt : För möjlighet till bättre erfarenhetsåterföring

Due to the obvious fact that one can never be hundred percent sure of what's hiddenunder the ground surface, construction work is naturally hard to project.However, many of the work methods are executed in the same way on variousprojects. The department of construction work at JM AB region öst describes a lackof follow-ups and feedback between the calculators and production managers.In this thesis we have studied the communication between these groups and alsohow they share experiences and knowledge. In order to get the full pictureof the day-to-day operations we used three methods to gather information. Studyingliterature gave basic knowledge of theories about feedback, and thenecessity of working with giving feedback. In order to understand the process ofconstruction work we made several interviews, both structured and nstructured.

Vätskebehandling inom brännskadevård

SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.

Bottensubstrat och dess inverkan på reducering av BOD5, COD och TKN i lakvatten genom konstruerade rotzonsanläggningar : En pilotstudie vid Univates, Lajeado ? RS Brasilien

Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice.  In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.

Tillverkningsanpassning av produkt för kostnadsreducering : Nya tillverkningsmetoder och verktygsparametrar

This thesis describes redesign and adaption of a products housing. In order to make it more economical to produce at a lower production volume. The thesis is based upon a prototype that a previous student developed for injection moulding. The goal is to find alternative manufacturing methods, but also to identify parameters that affect the cost of the injection moulding tool.The housing must be tough in order to protect the circuit board inside. But at the same time it must allow sound, light an electrical communication to pass through.

Naval surface fire support : en framtida svensk förmåga

Syftet med denna uppsats är att bidra till en ökad förståelse för NSFS samt att undersöka hurden svenska NSFS-förmågan år 2010 påverkar möjligheten att agera i enlighet med de militärateorierna. Den undersöker också om de militärteoretiska grunderna, den tekniska utvecklingenoch den förändrade inriktningen för Sveriges försvar medför ett ökat behov av NSFS-förmåga.Uppsatsen bygger på en deskriptiv metod där svensk försvarspolitisk inriktning, militära teorier,NSFS och svensk NSFS-förmåga 2010 behandlas. Huvudsakliga källor har varit litteratur, offentligttryck, doktriner och intervjuer rörande ovanstående områden. Begreppet NSFS har avgränsatstill att enbart beröra markmålsbekämpning med robot och artilleri. Uppsatsen visar attden svenska NSFS förmågan ger en begränsad förmåga att agera i enlighet med de militära teorierna.Anledningen till detta är att Visbykorvetternas artillerisystem är de enda tillgängligaNSFS systemen år 2010.

Habitatpreferenser hos tjockskalig målarmussla (Unio crassus) med avseende på vattendjup och beskuggning.

The thick-shelled river mussel (Unio crassus) is a red listed species classified as Endangered (EN) and is also considered within the Habitats Directive. The distribution in Sweden is fragmented and it is mostly occurring in the south eastern parts. We investigated the presence of Unio crassus in a section of the stream Storån, Östergötland County, from Falerum to the inflow into Lake Åkervristen. The environmental parameters investigated were water depth, bottom substrate, shading, water velocity and the slope over the water surface. In this thesis I have focused mainly on water depth and shading, comparing sites with and without mussels.

Sensory nerve conduction studies in young adults for the expansion of a reference material

Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.
