Utveckling av Mätmetoder för Färdmotstånd
The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.
Den lille Krigaren : - En studie om hur svenska SMF kan etablera sig på välutvecklade marknader
I denna rapport har vi valt att undersöka hur svenska SMF har gått tillväga för att lyckas etablera sig på en mogen och välutvecklad marknad. Genom att analysera det resursbaserade synsättet samt vilken etableringsform företag har använt sig av vid expansion så har vi haft som syfte att beskriva vilka specifika resurser samt vilken etableringsform som har varit viktigast för företagen när de har tagit beslutet om en expansion. Vi har vidare analyserat de barriärer och konkurrens som gjort att företagen valt att genomföra expansionen på ett specifikt sätt. För att kunna uppfylla syftet med uppsatsen har vi använt oss av en kvalitativ flerfallstudie med företag från olika regioner i Sverige.Vår teoriteska referensram har bestått av Barneys (1991) resursbaserade synsätt, olika etableringsformer samt Michael Porters (1980) teori om etableringsbarriärer.I vår analys så kopplar vi ihop vår teoretiska syntes med vår insamlade empiri för att kunna urskilja vilken/vilka resurser som har varit avgörande för företagens val av etableringsstrategier vid en expansion till en mogen marknad. Vi har även analyserat hur barriärer och konkurrens påverkat vid val av etableringsstrategier.Vi har baserat på denna analys kunnat dra slutsatsen att de teknologiska, entreprenöriella samt storleksmässiga resurserna har varit de mest essentiella resurserna för de undersökningsföretag vi studerat.
Populationsstruktur och genetisk analys av exteriöra egenskaper hos svensk ardenner :
The purposes of this study were to estimate genetic and phenotypic parameters for conformation traits in Swedish Ardenner, a heavy draught horse, and to investigate the inbreeding status of the population. Additionally, a breeding scheme proposal was created, based on the results achieved in the study.
The data studied were obtained from the Swedish Horse Board and from the Swedish Ardenner Association. The data included 1632 three-year-old horses, mainly mares, and 356 stallions, judged between 1986 and 2005 at conformation shows. The traits studied were type, head-neck-body, legs, walk and trot at hand, total score and height at withers.
Hylasmotivet hos Apollonios Rhodios och Theokritos
An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.
En långsiktig järnvägslösning i Stockholmsregionen : En studie av vilka krav Trafikverket bör ta hänsyn till i sitt planeringsarbete
Travelling by train has increased during the last decades in Sweden. This has put pressure on the existing infrastructure and has created problems with delays and cancelled departures. The railway is a complex system with mutual dependencies and high vulnerability for disruptions. The situation for the railway system in the Stockholm region is today strained. The capacity is fully used.
Tidsupplösning vid miljövärdering av fjärrvärme : Kontorsbyggnad med solvärmeproduktion - en fallstudie
The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.
Odlingsmetodernas påverkan på vitaliteten hos Prunus avium :
The objective of this study was to get a better understanding of how the cultivation methods influence the vitality in Prunus avium. The purpose was also to examine if there was any differences in shoot growth and trunk expansion depending on the method of cultivation. To find the answer to this question a literature study and a case study has been done.
The literature study concerns the concepts vitality and stress. Different definitions of these concepts are shown and their connection whit establishment is explained. In the background the species Prunus avium, and the four method of cultivation that are included in this case study are described.
Measurements of the shoot growth and trunk expansion were made in this study, and as a complement to these methods, a visual estimate of the vitality was made.

Hur en okontrollerad expansion av IT-projekts omfattning undviks
Today there is an even higher demand on IT-projects success rate compared to a few years ago. IT-projects must be handled more efficiently and result in a more profitable investment. In order to make the handling of IT-projects more efficient and create profitability the developers must have a broad understanding of the IT-projects characteristics and which factors that affect the result of the projects. Changes within IT-projects are often carried out through the development of a system. Since this change is more common when it comes to IT-projects it is important to handle risk and change within these kinds of projects in order to prevent and avoid uncontrolled changes.
Query expansion med hjälp av en elektronisk tesaurus i en bibliografisk online-databas.
In this Masters thesis we investigate query expansion using an electronic thesaurus. We formed 30 topics from the library and information science field. For each topic three searches were made in the bibliographic database LISA Library and Information Science Abstracts via CSA Cambridge Scientific Abstracts. LISA has an electronic thesaurus attached. We used this thesaurus to form baseline queries, baseline queries expanded with synonyms, and baseline queries expanded with both synonyms and related terms.
Utvärdering av Transportstyrelsens flygtrafiksmodeller
The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.
En detaljhandelsexpansion till Storbritannien - En finansiell analysav Clas Ohlsons etablering i London
Detaljhandelsmarknaden i Europa har vuxit sig allt starkare samtidigt har konkurrenssituationen ökat. Globaliseringen har medfört att gränsdragningen mellan länder minskat och internationalisering av detaljhandelsföretag har blivit allt vanligare. Clas Ohlson har med sin expansion i Norden stärkt sitt varumärke. För att ytterligare stärka sina positioner samt öka omsättningen har företaget valt att etablera sig på den brittiska marknaden med en första satsning i London. Clas Ohlson ser expansionen som ett steg att utvecklas från en nordisk- till en europeisk aktör.
Den framtida utvecklingen av expansionen är svår att förutspå vilket gör det svårt att prognostisera den framtida lönsamheten.
A quantitative analysis of global kiwifruit trade
New Zealand is currently the third largest global producer of kiwifruit and thus plays an important role in the international market. Exports of kiwifruit are also of significant horticultural value for New Zealand and in 2007 the kiwifruit industry accounted for export values of NZ$790 million.
The global kiwifruit market has experienced substantial changes in recent years and is likely to change significantly in the near future due to developments in production sources, adjustments to trade policy settings and shifts in consumer preferences. The New Zealand kiwifruit industry needs to consider what the impacts of these changes might be so that future strategies can be constructed effectively.
Little quantitative modelling has been done in New Zealand to consider the impacts of changes to the global kiwifruit industry. The major contribution of this research was the development and calibration of a kiwifruit industry-specific partial equilibrium trade model. The model was then used to examine the impacts on New Zealand producers of these trade-related changes in the global kiwifruit market.
Ombyggnation av operation gentemot alternativa byggmetoder : En konsekvensutredning för ombyggnad vid Löwenströmska sjukhuset
Over the next few years, major investments in healthcare buildings is to be performed. Most surgical theaters are in need of technological upgrades as the technology is outdated. In most cases not only a refurbishment is performed but also an expansion. The basis for expansion, is due to a large increased number of patients, but also to the complexity of the refitment. Partly it's because evacuations are difficult to implement and the disturbance that occurs in conjunction with the refitment.Löwenströmska hospital undergoing a technical upgrad.
Att expandera sökfrågor i en elektronisk bibliotekskatalog: En jämförelse av återvinningseffektiviteten för fyra olika sökfrågetyper
This Masters thesis deals with query expansion in an online library catalogue. The aim of the study was to compare the retrieval effectiveness of four different query types when applied to the online library catalogue of the University College of Borås. The query types were: an initial query, the initial query with right hand truncation, the initial query expanded with synonyms and finally the initial query expanded with synonyms and right hand truncation. 24 topics were formulated, and four queries for each topic were constructed. The records retrieved by the searches were judged with regard to topicality, and were judged to be non-relevant, partially relevant or relevant.
