Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel

Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.

Optimization of Burner Kiln 7, Cementa Slite

In this report focus is put on the combustion process at a cement plant. Combustion is the heart of the cement making process and absolutely crucial to have under full control and well optimized. The fuel is put into the process through a burner pipe and this burner pipe is modified to reach a more efficient combustion. The primary target is to enable burning of heterogeneous alternative fuels and increase the production level. Other positive effects from this type of optimization is lowered specific fuel consumption and lowered CO2 emissions. A redundant burner is chosen for the project and overall the project steps are the following: 1. Installing a Jet air nozzle ring in a way so it can move both axially and radially due to temperature changes. 2.

Optimering av OTEC-system

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

Att spara eller inte spara? : En kvantitativ enkätstudie av informationslagringssystem för vetenskapliga artiklar

Abstract PurposeThis thesis aims to focus on how master students administer scholarly articles after they have found them. The purpose of the study is to detect how and to what extent people administer their articles from a personal information management-perspective (PIM).MethodTo answer the research questions, a web-based questionnaire survey was distributed which was announced to around 2,000 master students from different universities in Sweden. Most of the items in the survey focused on individual storage methods. The respondents were asked to rate the frequency of their different information administration behaviors on a seven level Likert-type-scale. Subsequently, items concerning specific information administration behaviors were posed, followed by questions on the respondent's sociodemographic status.

Opraktiska kvinnor och krossade hjärtan : En studie av melankolin och kvinnosynen i Jack Kerouacs Visions of Cody

A growing need to strengthen ones position on the market, even as a city in competition with other cities, has resulted in an increasing number of municipalities developing brand platforms. When the city of Umeå developed their platform, they identified decision makers and investors as one of four important target groups.The aim of this study is to explore the portrayed image of the city of Umeå in two Swedish trade journals which addresses the specific target group decition makers and investors in both public and private sector. The aim is also to compare the image of Umeå in the two papers, to the ambition of the municipality, expressed in the brand platform.In order to make the observations as firmly established as possible, the method of the study is a combination of a quantitative content analysis and a qualitative text analysis. The study draws on the theories of Eli Avraham and Philip Kotler, concerning how to improve city images and how to market a specific city among others. The study shows that the city of Umeå in large extent is portrayed in accordance to the ambition which the municipality expressed in the brand platform.Umeå is displayed as an expanding city.

Konsultchefers upplevelser i yrkesrollen : En kvalitativ studie om konsultchefers rollhantering, känsloarbete och ledarskap på bemanningsföretag.

Vi har undersökt konsultchefer på ett bemanningsföretag. Syftet med studien har varit att ta reda på hur de upplever sina olika roller, vilket känsloarbete de utför i dessa roller, samt hur ledarskapet ser ut i chefsrollen. Vi har utgått från ett individperspektiv och med kvalitativ ansats intervjuat sex konsultchefer på ett bemanningsföretag, för att ta reda på vår frågeställning: Hur upplever konsultcheferna sina olika roller (som chef och säljare) och vilket känsloarbete utför de i rollerna mot konsulter och kunder? Denna har vi besvarat med hjälp av tre huvudsakliga teoretiska ramar: Goffmans (2009) dramaturgiska teori, Hochschilds (2003)teorier om emotionellt arbete och slutligen Sandahl et al.s (2010) teorier om chefens roll i organisationen. Undersökningen visade att konsultcheferna upplever det vara viktigare att ?hålla rollen? som säljare mot kunder, än rollen som chef mot konsulter.

The Swedish food retail market : An econometric analysis of the competition on local food retail markets

The Swedish food retail market contains of three major actors, ICA, KF and Axfood, all in all dominating 75 percent of the total market shares. The scant number of retailing actors indicates that the Swedish food retail market is a highly concentrated oligopoly, which as a fact has given rise to definite discussions and argumentations concerning the market situation. But is the food retail market imperfect and how do we reach a workable competition? Economic theory does not provide any clear answer on these questions, but is rather divided into two fundamentally different approaches to define competition: the static and the dynamic perspective on competition. In an attempt to examine the competition on local Swedish retail markets, the purpose of this study is to carry out an econometric model estimating the situation.

AbstractTitle: Level/Degree/Grade:Authors:Supervisor:Research question:Purpose:How the bank may improve its financial counselling ? A qualitative case study.Bachelor Thesis; Business administration; Corporate finance.Andreas A?strand, Anton Persson, Kristoffer Wedebrand.Hans Mo?rner.How may the bank improve its financial counselling to private investors using portfolio theory?Our purpose is to examine the advice, with basis in portfolio theory, the bank?s financial advisors provide to their clients, the investors, and how they can improve. If we can identify and point out areas of improvement in the financial counselling, we hope to raise the question and contribute with an improved financial counselling. Another positive effect we are hoping for is to improve the situation for the investors whereas all parties benefit from an improved portfolio selection.This study is conducted through a qualitative case study, where we used a deductive approach and collected our data through personal interviews.The conclusion that emerges is that the financial counselling could potentially be improved if financial advisors improve their knowledge in portfolio theory.The originality shapes through the opportunity to investigate a specific bank and because of that an opportunity to examine a specific case more thoroughly was created. Our thesis contributes with opening La?nsfo?rsa?kringar?s and other banks? eyes to how their financial counselling could be improved through new knowledge in portfolio theory.

Tredimensionell fastighetsindelning : med fokus på tillbehörsproblem

Real estate is defined as ground, which is divided into property. Ground means every part of the surface, which is situated within the country. There is no legal definition of property to be found. Property is usually explained as every unit, which legally should be registered in the register of landed properties. To constitute a property the property must permanently be suited for its purpose.

Byggnadsminnesmärkning eller varför är det så ont om Q?

This thesis deals with our heritage and the care of old buildings. In order to limit this vast area a specific attention has been brought upon the process of giving buildings a certain level of protection and after decision having it taken away, instead of giving a stronger protection level.Further limitation has been done through the choice of four buildings in Lund, within Lund University campus. These buildings all lost this certain level of protection. The participants in these kinds of cases have a level of power, what argumentation did they use?The methods being used are discourse analysis, phenomenology and the daily methods of the building care field..

UNDER YTAN Fredrik Reinfeldt och Stefan Löfven i en komparativ bildstudie

Title: Under the surface - Fredrik Reinfeldt and Stefan Löfven in a comparative photo studyAuthors: Jon Demred, Fanny Wijk & Olivia WikströmLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 39This thesis compares how Stefan Löfven was being portrayed in Swedish media the week after the generalelection 2014 with how Fredrik Reinfeldt was portrayed in the first week after 2006?s general election.There has been made a lot of research on how politicians are portrayed in the media, but most of theresearch focus on text portrayal. This thesis focus on something different, it compares how the two ?winners? were portrayed in news photos.A semiotic approach was used to analyse news images in the newspapers Aftonbladet, Expressen, SvenskaDagbladet and Dagens Nyheter. It was important to not only look at the pictures, but also the outer context, i.e the headlines, had to be analysed to come to any conclusions.Fredrik Reinfeldt was portrayed more positive and more as a winner than Stefan Löfven was.

Fallstudie på Andritz - Styrkortets utformning och användning : -

The purpose of this essay is to analyze and understand how producerbrands are able to communicate their brand through today's marketing channels, also how development and changes that occur in the society can affect the producers communication abilities. We have seen a tendency that many retailers have created their own brands that are competing with the producers, this leads to the fact that producers in some cases are having trouble communicating their brand to the end-consumer. The fact that the producers marketing through retailers now is more limited than before, the producers now have to capture the consumers wants and needs through other channels.This essay is based on a qualitative method involving seven interviews. The persons that we've chosen to interview are carefully selected based on their specific knowledge about the subject in question..
