Analys av sprickdetektion vid automatisk avsyning av granvirke : med avseende på sprickors bredd, längd och djup

Examensarbetet syftar till att hitta samband mellan ytliga sprickor hos virke, i form av dimensioner och karaktärer, som dagens maskinella avsyningssystem inte klarar av. Tyngdpunkten i projektet har legat på att identifiera eventuella samband mellan verkligt djup hos sprickor och de ytliga sprickmått som kan uppmätas med automatisk avsyning av WoodEye. I huvudsak har projektets praktiska undersökningar gått ut på att bestämma sprickors ytliga dimensioner, djup, typ och position med hjälp av automatisk avsyningsutrustning (WoodEye) samt genom manuell uppmätning i ett antal itusågade sprickzoner. Det provmaterial som använts i utförda försök och som legat till grund för efterföljande sprickanalyser har varit av sådan karaktär att det kunnat jämställas med konstruktionsvirke som normalt sett hållfasthetssorteras enligt europasstandard SS-EN 14081-1.I projektet har 568 sprickor, fördelade över 8 olika spricktyper, analyserats. Av erhållna resultat har det konstaterats att störst respektive minst medelbredd uppvisades hos kådlåpor respektive kantsprickor, störst respektive minst medellängd uppvisades hos splintsidesprickor respektive kådlåpor, samt att störst medeldjup uppvisades hos fäll-, kap- och stormsprickor.

The primary purpose of this study has been to investigate the Swedish timber industry?s perception of compression wood. A secondary aim has been to describe particular areas within the production process where compression wood is likely to cause problems. This study has mainly been carried out as a questionnaire. In order to connect the findings to current research, additional information has also been collected by means of a literature review. The questionnaire has been intended for sawmills and wood-manufacturing companies from various production classes and owner categories, as well as from different parts of the country.

Spridning av bekämpningsmedel i banvall : Modellutveckling och känslighetsanalys

The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.

Gymnasieelevers förståelse av enhetscirkeln och trigonometri : en undersökning av elevers förståelse av matematiska begrepp, samt vad lärarna anser att nyblivna matematikstudenter bör kunna när de kommer till högskola eller universitet

The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

"Vill du missbruka så blir vägen rätt smal" - Förklaringar till varför hemlösa kvinnor med missbruksproblematik utesluts från den reguljära bostadsmarknaden

The background of this study stemmed from the notion that the majority of homeless women with substance abuse, most of all, wanted a secured place of their own to stay. Few involved professionals agreed and instead of perceiving housing as a human right the women were mostly offered various types of short-term social housing. The purpose of this study was thus to examine and analyze how professionals attached to the social services and public housing companies in Gothenburg explained that homeless women with substance abuse were excluded from accommodation on the open housing market. The qualitative approach included ten interviews with eleven professionals in Gothenburg. The theoretical framework consisted mainly of Bourdieu's analytical concepts of field, doxa as well as social, economic and cultural, alongside symbolic capital.

Omkonstruktion av kolvlod : På uppdrag av institutionen för geologiska vetenskaper Stockholms universitet

On ocean beds around the world sinking particles of residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth?s past climate, information that can be used to predict future climate change and to estimate natural vs. human causes of today?s global warming.The Institute of Geosciences at Stockholm University studies sediment cores that have been acquired with an apparatus called piston corer.

Koncept - detalj - byggnad

Concept - detail - buildingStockholm International Fairs, new main entrance I studied at the KTH School of Architecture from 1995 to 2000. After completing my studies I wanted to work in an office that had a structural way of thinking and that knew the building process; I therefore chose to work for Rosenberg Architects. I have worked on a number of projects, among them several for the Stockholm International Fairs, from the Rica Talk Hotel and Hall AE, to the new main entrance.In the projects we undertook at the School of Architecture we had to identify and draw details that were central to our concepts. I have here identified some key details that we considered to be essential for the concept in a built project; the new main entrance of the Stockholm International Fairs completed in 2013. The entrance has complex logistics with multiple intersecting flows: exhibitors, employees, journalists, VIPs and others.

UTV?RDERING AV APPLICERINGSTEKNIKER MED LASCAUX 303 HV Adhesivet Lascaux 303 HV anpassningsbarhet vid strukturella ?tg?rder p? m?leri p? duk

Lining techniques such as nap bonding and mist lining were developed in the late 20th century and have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced, which can be advantageous for more sensitive paintings. These lining techniques have been included in several studies where reversibility, minimal intervention and respect for the individual requirements and problems of each object have been the focus. The adaptability of the methods has been confirmed and to further explore the adaptability, this study consists of three simpler application techniques with the adhesive Lascaux 303 HV on mockups.

Utbildade invandrare och kampen för ett jobb : En kvalitativ studie om hur några invandrare med akademisk utbildning beskriver sin situation på den svenska arbetsmarknaden

According to several studies immigrants today in general face more difficulties to enter the labor market than before. This also applies to educated immigrants who are the main focus of this thesis.Studies have shown that educated migrants have more difficulties of obtaining an adequate job than ethnic Swedes. Thousands of educated immigrants are forced to work in low skilled occupations to cope with their everyday lives. The reasons behind their lack of success on the Swedish labor market have been blamed on different kinds of obstacles.     This study wants to examine at least some of the obstacles that educated immigrants face on the labor market through some informants own personal reflections and experiences. The study is based on an inside perspective in which the different personal experiences and reflections of the various informants is of great importance.  The study is focused on how five educated immigrants describe their situation on the Swedish labor market. The aim is to investigate the informants 'understanding of the difficulties they have to get a job that matches their skills. It also aims to discuss the structural barriers that respondents relate to when they describe their situation.    The results of the interviews with the informants have been analyzed with the help of central concepts gained from the two sociologists, Erving Goffman and Pierre Bourdieu.

Etnisk diskriminering- från arbetslivet till Arbetsdomstolen? : En granskning av Arbetsdomstolens praxis gällande etnisk diskriminering

The right to non-discrimination is a fundamental part of human rights. Sweden has enacted legislation which prohibits employers from discriminating or harassing employees and job seekers. Swedish authorities also receive a substantial amount of complaints concerning ethnic discrimination in the workplace every year and there are volumes of research showing structural injustices related to discrimination. Despite these facts few employers have so far been found guilty of discrimination on ethnic grounds in Swedish courts.This thesis aims to shed lights on and analyse how the Swedish anti-discrimination legislation is utilised in the Swedish Labour Court regarding discrimination and harassment on ethnic grounds. On the basis that very few lawsuits brought on behalf of employees/job seekers have been successful it is hypothesized that there are problems either with the form of the legislation or the assessment of the court.

Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.
