Syftet med studien har varit att undersöka möjligheten att skapa en enkel modell att undersöka optimal hantering av avfall i Sverige. Den modellen skulle i så fall ingå som en del i ett regerings uppdrag om det är möjligt att sätta upp ett nationellt miljömål mot ökat effektivt användande av resursen som avfall utgör. Studien har utförts på uppdrag av Naturvårdsverket inom ramen för examensarbete inom civilingenjörsprogrammet i kemiteknik på KTH.Inledande genomfördes ett antal intervjuer för att skapa en god bild av hur avfalls Sverige ser ut och inom vilka områden det finns potential för optimering. Sedan studerades artiklar, böcker och rapporter samt en stor mängd statistik som tillhandahölls från Naturvårdsverket samt RVF undersöktes. En bild av hur modellen skulle behöva se ut togs fram.

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

This project is about Jönsaplan in Landskrona. Jönsaplan is situated at the center of Landskrona in a part called Södra centrum which the municipality is developing, mainly by building new residential buildings. Today, Jönsaplan is not a functioning square. This is due to a ferry terminal and its many fences that block the way for people. In this project, I have assumed that the ferry terminal will be moved somewhere else so that Jönsaplan can be a real square. By studying The Concise Townscape by Gordon Cullen and Byens uttrykksformer by Thomas Thiis - Evensen and three reference places, Daniaparken, Raoul Wallenbergs torg and Norr Mälarstrand, I came up with a number of guidelines for my design proposal for Jönsaplan.

Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication  due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences  that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin.  The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.

The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.

Purpose: To contribute to the understanding of the relationship between private labels and the retailer brand in grocery retailing. Methodology: We use structured interviews as a cross-sectional method for quantitative data collection. The existence of the relationship is tested through correlation analysis and regression analysis. Theoretical perspective: Perceived quality of private labels and of retailers are the main theoretical concepts for this thesis. Additionally, we introduce the concept of loyalty to show the benefits of a positive consumer image.

Syftet med denna studie är att förklara varför konsumtionen av ekologiska kläder haft en svag ökning sett utifrån konsumenternas perspektiv. För att kunna besvara syftet har en kvantitativ metod legat till grund för denna studie. Data har samlats in med hjälp av enkäter för att undersöka om det föreligger något samband bland konsumenter. För att kunna presentera ett mer djupgående resultat har den kvantitativa metoden kombinerats med en kvalitativ metod vid analys av data.Teorin i denna studie har använts som utgångspunkt för att bättre förstå konsumenternas köpbeteende samt betydelsen av varumärken. Studiens empiri består av den data som samlats in genom enkäter.

Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.

This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.

Bakgrund och problem: Fastigheter och fastighetsföretag har med jämna mellanrum blivitaktuellt, ibland ser man att de agerar till synes olika. Det vore intressant att såförutsättningslöst som möjligt studera vad ett antal av de svenska fastighetsföretagen gör.Ett sätt att göra det på kan vara genom att ta del av deras årsredovisningar ochsammanställa informationen som visar vad man har gjort samt hur företaget är strukturerat isyfte att underlätta för fortsatt studier av företagen. Det har utmynnat i följandefrågeställningar:Vad gör ett antal av de stora svenska fastighetsföretagen?Samt:Hur kan man gå tillväga för att använda insamlad data i vidare studier för att beskrivaföretagen?Syfte: Att ställa upp informationen på ett sätt som gör att läsaren kan skapa sig enöversiktlig bild av ett antal företags struktur samt beteende under 2009. Att samla in ochställa upp data som ett underlag i syfte att bereda för fortsatt forskning.Avgränsningar: Studien omfattar endast svenska stora fastighetsföretag vars primäraverksamhet är att äga och förvalta fastigheter.

This thesis examines how Swedish newspaper media problematize surveillance. This is done by analysing the media reports from two major surveillance events: the debate in 2008 about the legislation concerning the expansion of the rights of Försvarets Radioanstalt to monitor internet and telephone traffic crossing the Swedish borders, and the revealing of an ethnically based index including over 4000 individuals created by the Swedish police. The thesis sets out to expand the knowledge about media?s role as a interpreting source of information concerning how people understand and relate to surveillance (Barnard-Wills, 2011; Carlsson, 2009; Greenberg & Hier, 2009). The thesis attempts to answer the question whether Swedish media problematizations regarding the abovementioned surveillance events correlates with the most common theories of surveillance critique.

WordPress är ett av världens mest populära Content Management System. Eftersom det har en hög popularitet drar det till sig uppmärksamhet från personer och grupper som av olika anledningar vill utnyttja säkerhetsbrister på webbsidor. Syftet med denna uppsats är att testa säkerheten i olika tillägg till WordPress som externa utvecklare skapat eftersom dessa inte genomgår någon obligatorisk säkerhetskontroll. Insamlingen av data skedde via ett utförande av statiska tester på några utvalda tillägg. Denna teknik grundar sig i en granskning och analys av dokument i form av text, modeller eller kod.
