Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques
This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.
Kartläggning av spånproblem i GG8 : avdelning 9460 Volvo Aero Corporation
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
Kostnadsallokering genom ABC-kalkylering – en empirisk studie av OMX
As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.
Orden bakom klimatet : Oppositionens interpellationer i en tid av klimatkris
This paper examines interpellations made in the swedish Riksdag and how they are rhetorically structured to effect and hold government officials accountable in climate policy.?The analysis methodology applied is rhetorical analysis, which aims to identify rhetorical argumentative strategies in the opposition's interpellations between three different periods, 2015-2018, 2019-2022 and 2022-2025. These strategies are ethos, pathos and logos, they are used as glasses in which a rhetorical analysis is conducted on the material. The study reveals that the rhetorical strategies differ between the time periods and that the political rhetoric has become more value loaded over time.? .
Supermarket Strategies : Kvalitativ studie av Ica Maxi, Coop Forum och Citygross konkurrensstrategier
This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.
HFDs hantering av regelkollision mellan intern rätt och skatteavtal : En analys av RÅ 2010 ref. 112
The OMX-case entailed considerable uncertainty about the relationship between tax treaties and Swedish domestic law. Previous approaches to handle rule conflict between them was put out of action for the first time when an internal rule took precedence over tax treaties. The Greece-case came a few years later where there were hopes that it would be decided in plenary session to return to the view that prevailed before the OMX-case, which did not happen. Instead the Supreme Administrative Court ruled that the tax treaties shall in principle be given preference, but that in exceptional situations tax treaties can be infringed to an internal rule's benefit, so called tax treaty override. Such procedure is acceptable if the legislature gives "clear expression" of the intention of a certain type of income is to be taxed in Sweden, or that a particular new rule applies regardless of the provisions in tax treaties.The purpose of this thesis is to analyze the supreme administrative courts management of rule collision between domestic law and tax treaties in the Greece-case.
Analys av fastighetsbolagens möjlighet att klara en ny lågkonjunktur. : En kvantitativ studie av fastighetsbolag i Europa
The goal of this thesis was to explore how real estate investment companies are affected by a weaker world economy. The reason to investigate this was that in the 90s in Sweden, the housing market crashed in conjunction with the bank collapse. Therefore I have looked at how the commercial real estate companies would be affected if we were to have a double dip recession, because it has been confirmed by Gyourko that commercial real estate market and the housing market tend to react in the same way on new fundamental information. This was examined through a sensitivity analysis, one investigated the effect of falling rent income and the second analysis looked at the effect of higher interest costs. I found that IAS 40 rule about unrealized profits of properties affected the results in a significant matter and therefore decided to include the regulation in my thesis.
Effektiva lösningsmetoder för Schrödingerekvationen : En jämförelse
In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF (LF4)and CN (CN4) were also studied, though these showed no improvements overLF2 and CN2. All methods were shown to exhibit symplectic behavior..

Vikingatida eller medeltida kammar i Västergarn? : en fallstudie av enkelkammarna funna vid Högskolan på Gotlands seminariegrävningar i Västergarn mellan åren 2006-2011
The University of Gotland has between the years 2006-2011 conducted seminar excavations in Västergarn parish, Gotland. During this time 167 comb fragments have been registered. Out of these are 51 of importance for this study, since they are defined as either a single-sided composite comb or a comb case. The purpose of this thesis is to enlighten the earliest period in the history of Västergarn by focusing on the earliest forms of combs and their cases. And as the title expresses do the combs date to the Viking Age or the Middle Ages? The combs from the excavations will be compared to different type schemes, both Viking Age and Middle Age and different places in Scandinavia such as Lund, Oslo, Lödöse and Gotland.
Geografiämnet på gymnasienivå : En undersökning om geografilärarens koppling till läroplan och kursplan i undervisningen samt dennes undervisningsformer
The purpose of this essay is to study how the local creators of a "master plan" for the swedish city Kristinehamn, the years between 1940 to -43, looked on their planning. It is an analysis of ideas case study. A hypothesis is upheld for the research: that the local physical planning had largely extended ambitions what regards central state control in a way that is similar to planned economy. Questions that are asked include: Was the planning assumed to be a tool for the state to regulate the environment? Can the planning be seen as a mean to control the society in time and space? The essay search for verification of the hypothesis by a theoretical analysis apparatus made upp of ideal types.

Strategier för positionering av kontorslokaler
The report aims to examine how property owners position themselves to reach their targetmarket, and which strategies they use when positioning their product. The investigation has beencarried out mainly in the form of a case study in which a number of interviews with Stockholmreal estate companies has been conducted, focusing on commercial property market segment.The interviews have resulted in identification of common and specific strategies among thecompanies. These strategies have been analyzed in the light of the theory by Philip Kotler andKevin Lane Keller, focusing on how an offer should be designed to reach a competitive position.It can be concluded that positioning is a key activity for successfully addressing the targetmarket. Successful positioning mandates three key requirements to be met; determining thecategory to which the offer belongs, identifying similarities and differences compared to thecompetitors and developing a brand mantra. The result of the case study concludes that theproperty companies work similar in many ways.
Mätning av axiella magnetiska läckflöden i vattenkraftsgeneratorer
This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering. To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.
