Ett blink i bruset: En uppsats om möjligheten att påverka konsumenten vid livsmedelsinköp
Today endless choices exist for a customer in the grocery store in terms of information, products, brands and prices. Consequently, it is important for retailers and brand owners to gain insights in how they can manage to break through the clutter to reach the customer. Displays that include some kind of motion element are assumed to possess an attention grabbing ability, which is a necessary first step in influencing the customer?s decision making. Therefore we have explored whether so called dynamic displays are efficient in grabbing attention and influencing customer behaviour.
Rådjur (Capreolus Capreolus) på Gotland : populationsutveckling och spridningsmönster
Gotland is an island in the Baltic Sea where man has introduced roe deer. The last successful reintroduction was in the 1980s and is the base of the viable roe deer population of today.The aim of this study was to estimate the roe deer population density in 2012 and the species population dynamic since the time when studies on the population started. The result indicates a population size of 850 roe deer in 2012. There was no significant population dynamic, which may be due to insufficient data. The population occurs basically over the whole island but have not yet been established in all suitable areas.

The objects of investigation are 20 glulam beams. The firstfield measurement took place in november 2007 and applied a staticmethod based on the standard SS-EN 408. The second measurement,described in this study, took place during summer 2010, and appliedstatic as well as dynamic methods.The MOE of wood is affected by a range different factors.
Sveriges Radio - Public Service : Den digitala vägen till nya användare
The purpose of this report was to study how the Swedish radio channel Sveriges Radio (SR) website changed over time. What are the differences between various media websites? How many people listen to normal and web-radio and what are the differences between the various services offered on the SR website?Reports from the BBC, Statistics Sweden, Mediavision and the Swedish National Post and Telecom Agency were compared. Several theoreticians have been studied, including Donald A Norman, Jonas Löwgren, Karen Holtzbratt, Jacob Nielsen and Geoffrey Moore.The method used by the author comprised a systematic mapping of statistics from webTrends, KiaIndex, SiteCensus, TNS Gallup/K2analys and reports from RUAB. The data studied have been collected from telephone interviews, postal surveys, internet panels, and from log files.
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.
Interaktionsdesign för kommersiella webbtjänster
The company Microshop is interested in implementing new features in their product-website, and would like to examine the possibility and usefulness of introducing such functionality. When designing interaction for commercial websites, it is important to make the menus easy to use, and refrain from using deep hierarchies in order to avoid causing unnecessary burden for the users. There is an interest among users for adaptive functionality, but this requires great amounts of trust in the website from the user. Something which can be created by refraining from using implicit information, and provide detailed explanations throughout the website. A usability test was conducted in order to complement the data gathered from the theoretical study, the interviews and the expert evaluations.
DDoS: Ett evolverande fenomen / DDoS: An evolving phenomenon
Internetfenomenet ?Distributed Denial of Service?, förkortat DDoS, beskrivs ofta som ett av de
största hoten mot Internet idag. Genom att utnyttja den grundläggande strukturen i kommunikation
mellan nätverk och datorer kan kriminella blockera och stänga ute webbplatser och -tjänster från
användare, samtidigt som det är mycket svårt för offret och myndigheter att någonsin identifiera
den eller de skyldiga. Enorma globala nätverk av ovetande människors infekterade datorer fjärrstyrs
till att utföra angrepp mot alla sorters organisationer på Internet med olika motiv, som finansiella,
politiska eller för ren vandalism. Syftet med det här arbetet är att göra en dagsaktuell kartläggning
över läget kring DDoS-angrepp och titta på statistik över de mest förekommande angreppstyperna,
och se om den nyare publicerade forskningen kan svara på de pågående och framträdande trender
som kan ses.
BIM vid installationsprojektering
Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.
Smart Control : En reaktion på EU:s ekodesignkrav
The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency.
Distribution av sportevenemang via strömmande medier och webcasting
Användandet av strömmande medier har ökat explosionsartat under de senaste åren. Oavsett om det sker märkbart för användaren eller inte använder sig gemene man i princip dagligen av någon form av tjänst som distribueras via strömmande medier över Internet. Det kan röra sig om allt från att lyssna på webbradio till att titta på videoklipp från nyhetsportaler eller sportsidor på Internet. I denna rapports första del görs en kartläggning över strömmande medier rent generellt. Den läsekrets som inte är särskilt insatt i ämnet får reda på vad strömmande medier är, vilka aktörer som finns på marknaden, möjliga distributionssätt, historik med mera.
Streaming av olovligt tillgängliggjorda verk - En ansvarsutredning : En ansvarsutredning
Streaming är en teknik som används för att se på direktsändningar eller filer som är lagrade på webbplatser, direkt på datorn, utan att filer sparas. Det har blivit ett sätt att komma runt förbudet mot att ladda ned film men rättsläget vad gäller streaming är idag oklart. Med denna uppsats avser vi att undersöka gällande rätt, om en lagändring bör ske och vilka aktörer som kan hållas ansvariga vid streaming av olovligt tillgängliggjort material.Upphovsrätten är idag reglerad på många olika plan, det finns internationella konventioner och avtal, EU-regler och nationella regler. Inom Sverige förekommer regleringen främst i Upphovsrättslagen (URL). De internationella bestämmelserna syftar till att ge skydd åt upphovsmän, oberoende av nationalitetsgränser, och detta har i sin tur inverkat på EU-direktiv.
Value-at-Risk : Historisk simulering som konkurrenskraftig beräkningsmodell
Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.
Ett världskrig utifrån ett eurocentriskt perspektiv : En kvalitativ analys av historieläroböckers skildringar av andra världskriget
The purpose of this study was to identify the way in which history textbooks from the 1980s, 1990s and 2000s used for grades 7-9 depicts World War II from a eurocentric perspective. A qualitative textual analysis was used to achieve the purpose. Three history textbooks from each decade was included in the study, also comparisons have been made to see any changes over time. The study used John M. Hobson matrix describing how the Occident and the Orient are defined from a eurocentric perspective.
Mätning av dynamiskt tryck med piezoresistiva tryckgivare på roterande objekt
The report handles the transmission of signals from piezoresistive pressuresensors and thermocouple from a rotating object. This report also evaluates the possibility to collect data in a datalogger that rotates with the object. Telemetrics was previously used for signaltransmission in Finspång, therefore there has been no tests considering preassure measuring. One transmitting method handled in this report is transmission through a slipring connection. One test with a slipring connection was performed for transmitting signals from a piezoresistive preassuresensor.
