Plantinventering och plantkontroll med digitala bilder från helikopter :

This study was carried out as a commission from Holmen Skog, district ?Egen skog? in Norrköping. During October 2006 several stands were inventoried by aerial photos from helicopter. The stands were those for which the next action proposed was plant inventory or plant check. The photos were interpreted and the number of stems was calculated.

Teknisk undersökning av stafflimåleri ? Med fokus på två dörröverstycken från Röhsska museet

This bachelor thesis is a study in the analysis of paintings with focus on the technical exami-nation within the framework of ATSR. ATSR is a methodology based on an interdisciplinary study with the aim of putting the object in its context.The study is based on questions concerning which information the object can give, how we access this information and how it can be put in a larger context. My thesis contains three major parts. First a short overview of methods of analysis used in this form of investigation is presented. This is followed by two case studies which exemplify the technical investigation.

Undersökning av fosfatsbegränsningseffekter på Escherichia coli AF1000 för bättre förståelse av 3-hydroxybutyratproduktion

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

Miljöbyggnad, GULD värt? : En undersökning av fastighetsägares erfarenheter och tankar kring ett nytt certifieringssystem

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

Utvärdering av vibrationer inom vattenkrafts normer

The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.

För vem är friheten större? - Hur Vellinges politiker tänker i flyktingfrågan

Vellinge is one of few municipalities in Sweden that refuses to accept refugees. The subject of this thesis is to find out how the local politicians in Vellinge make their considerations when they decide not to welcome refugees. The analysis uses the representation theory as a starting point. The two ideals of the representative role, either as a bound mandate or as a free independent role, is the base of the analysis. Vellinge is in the analysis compared to Lomma, a very similar municipality in southern Sweden that for a long time alsohas refused to accept refugees, however suddenly in 2007 decided to change their mind.

Konvertering från luft till vätskekylning av elektronik

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Det målande barnet. Diskursanalys av estetiska läroprocesser i relation till Deweys estetiska erfarenhetsbegrepp.

THE PAINTING CHILD. A DISCOURSE ANALYSIS OF AESTHETIC PROCESSES OF LEARNING IN RELATION TO DEWEY´S ART AS EXPERIENCE.The aim of this study is to present a discourse analysis made on five-year-old children during art activities in a preschool in Sweden. The questions asked are: how does interaction take place between the children, or the child and the teacher, during art activities? And what does this tell us about the relationship to art in preschool? In Art as Experience John Dewey claims that art is separated from other experiences of life, but that it ought to be close to ordinary life-experiences. Today visual culture is important in society but not in school.

Nya Slussen i dagspressen : En kvantitativ innehållsanalys och kritisk diskursanalys av Dagens Nyheters, Svenska Dagbladets, Expressens och Aftonbladets rapportering om Nya Slussen

The reconstruction of a central area in Stockholm named Slussen (The sluice) has frequently been portrayed and debated in media over the last few years, escalating around December 2011 when the major decision regarding Slussen was to be made by the city council. The area serves as a traffic node connecting the areas of Södermalm and Gamla Stan (Old town) together. The last major change of Slussen was completed in 1935, best described as a modernistic traffic and architectural piece of work. It is indisputably an area of importance for the city of Stockholm, its citizens and visitors. How has media reported the development of the New Slussen project?The analysis, and the conclusions drawn from it, will be based upon and performed with a quantitative content analysis and critical discourse analysis.

Membranbioreaktorteknik- en framtida lösning på Lundåkraverket? : Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

Pojkars och flickors brinnande intressen : En analys av 10 elevtexter ur ett genusperspektiv

The main purpose of this study is to analyze texts written by pupils during the national test in the subject Swedish for grade 9 in order to identify and illustrate how they have met the instructions for the writing task including genre. The texts have been analyzed using Palmér & Östlund-Stjärnegårdh?s (2005) model for student text analysis. This model has been supplemented by studying word and sentence length, as well as indexes for level of readability (LIX) and word variation (OVIX) in order to illustrate possible differences in a gender perspective. The results of this study are in line with previous research, as the girls? texts are longer and more descriptive, while the boys? texts are shorter and show a wider range of word variation.

Interaktiv skrivtavla i undervisning : En multimodal fallstudie av en lärares användning av interaktiv skrivtavla i läs- och skrivundervisning

The aim of the study is to investigate how a teacher uses multimodal resources with an interactive whiteboard while teaching reading and writing. The aim is also to investigate what view the teacher has on using an interactive whiteboard while teaching reading and writing. Video-recorded observations and audio-recorded interviews are the methods used to collect data. The analysis was performed from a multimodal perspective and is also inspired by interaction analysis. The result of the analysis showed that the teacher uses several multimodal sign systems in combination with those found on the interactive whiteboard.

Medborgardialog i ortsanalys : ett arbete om värdet av kommunikation tidigt i planeringsskedet

Citizen participation is fundamental in place analysis, where the aim is to define the sites specific character and identity. The local citizens know the village better than anyone else since they lead their daily life in the environment. I have in cooperation with Sala municipality suggested guidelines on how to involve the local people in dialogue during place analysis. The target was to involve and enthuse as many people as possible with relatively small resources in time and money. The suggested methodology was tried out in a place analysis of Västerfärnebo, a community with about 3 000 inhabitants of which 500 live in the main village.

Höghållfast stål : Optimerat materialutnyttjande i byggnadsstommar

I detta examensarbete utförs en jämförelse av HSQ-balkar och VKR- pelare i hållfasthetsklass S355 respektive S460. I arbetet dimensioneras profiler anpassade efter studerade fiktiva konstruktioner och ställs emot varandra. Syftet är att optimera profilerna och effektivisera stålanvändningen. Förhoppningen är att en applicering av höghållfast stål i vanliga konstruktioner medför en reducerad stålmängd. Är minskningen tillräckligt stor bidrar denna i sin tur till en mindre miljöpåverkan samt kostnadseffektiva dimensioneringslösningar.Två olika byggnadsstommar utförda i stål med sträckgränsen 355 respektive 460 MPa undersöks.

Hur påverkar logistikplaneringen byggarbetsplatsen? : En enkätundersökning om logistikkostnader i produktion

Logistics planning for a construction site is usually limited by traffic flow to and from the workplace. The geographical location of the construction site is determined by roads around the workplace and opportunities for well-functioning logistics. Inventory of material is often impossible because of the frequently small workspaces. As a result, a concern relating material handling remains . Even before the establishment of a construction site, it is required in the construction industry to eliminate errors that might arise in the planning stage.
