Undersökning av exponeringsindex för bildplattesystem inför optimeringsarbete

The county hospital of Dalarna has for the last couple of years carried through a process of digitalization. The result is that within the county it exists image plate systems from two different manufacturers. In an attempt to create a tool for dose optimization and dose surveillance the county of Dalarna would like to investigate if the Exposure index from Agfa and Fuji is suitable as a dose indicator. An investigation of the Exposure index, S, from Fuji has already been done. This thesis has been continuing the investigation by evaluating the stability of the Exposure index, lgM, from Agfa.

Kreativ produktexponering inom e-handeln

This study investigates whether creative online product exposure within the clothing industry has a positive effect on the behaviour and attitude of today's consumers. Product exposure is the most important stimulus in the online marketing universe, yet few studies exist on this topic. Thus, this study pioneers in this specific research field. Through empirical analysis this study reveals that product exposure has a significant and direct effect on the perceived corporate ability and consumer involvement. Moreover creative product exposure indirectly increases the perceived product quality, intention to buy and the overall attitude towards the brand.

Metod för dosoptimering av digitalt detektorsystem i klinisk drift

The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An Exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.

Empirisk undersökning av aktieindexobligationer : Till vilken grad tar innehavaren del av underliggande index avkastning?

The purpose of this essay is to evaluate stock index bonds return to risk ratio in order to investigate to which degree an investor in a stock index bond take part of the underlying index return and what the investor must pay for the security of not losing his funds. In order to carry out this evaluation an average return per year and the Sharpe ratio will be calculated and a mean- standard deviation analysis will be made. All investigated stock index bonds are based on a Swedish underlying asset.The results show that the stock index bonds haven?t generated a higher risk adjusted return than its underlying asset. The stock index bonds took part of 57 % of the underlying assets return, and the loss of 10 percentage points per year for the stock index bonds compared to its underlying asset can be seen as the cost for the guarantee a stock index bond gives..

Redogörelse av marknadsstyrka på den svenska elmarknaden

Denna uppsats syfte är att förklara den svenska elmarknadens konkurrenssituation med Lerner index och Herfindahl index. Genom att estimera priselasticiteten med en ekonometrisk modell som logaritmerats kunde dess värde skattas fram. Vidare har denna elasticitet använts för att skatta fram Lerner index. Avslutningsvis har ett Herfindahl index beräknats för att mäta marknadens koncentration. Resultatet från empirin visar existens av marknadsstyrka på elmarknaden och att den är oligopolistisk..

Konfigurering av slutartider för ljusdetekterande mjukvara

This project measures the upper bound of exposure time for laser reflection detection in the software DotDetector. Via measurement of the exposure time for which distortion happens in a room lit with everyday light we conclude that the upper bound for exposure times are 100 milliseconds. This value does not change as long as the lighting in the room is the same. As future work this project proposes variable upper bounds depending on secondary lighting in the room. Also we propose automating the colour masking of the detection algorithm..

Vikten av ett oviktat index

Syftet med denna uppsats är att undersöka ett oviktat index relevans som jämförelsemått för aktivt förvaltade fonders avkastning och förvaltares förmåga att hitta vinnaraktier. Arbetet använder sig av en kvantitativ metod för framtagning av ett oviktat index (SUWX 100) som inkluderar de 100 största företagen på Stockholmsbörsen. Analysen av kvantitativa data är av induktiv karaktär, och använder sig av de Sverigefonder som finns i PPM-systemet för att dra slutsatser kring det oviktade indexet som jämförelsemått. Vår slutsats är att det finns aspekter av ett oviktat index som gör det användbart som jämförelsemått för Sverigefonder..

Alternativa index - En studie av mean-variance-effektiviteten hos index baserade på fundamentalvärde kontra börsvärde

Finansiella index är viktade genomsnitt av olika tillgångars avkastning från en bestämd tidpunkt. Traditionella index är börsvärdeviktade. Problemet med denna typ av index är att börsvärdet tidvis kraftigt kan överdrivas på grund av spekulation. Alternativa index bygger på företags fundamentalvärden. De viktas därmed efter företags faktiska redovisade siffror i balans- och resultaträkningar.

Hållbarhetsredovisning : En studie av Vattenfall AB i ljuset av GRI

This essay is about democracy and how a democracy index can be used as a tool to illustratethe gap between reality and ideal. The purpose of this study can be expressed by two researchquestions: Does the Economist Intelligence Unit's (EIU) democracy index illustrate thedistance between reality and the ideal of democracy presented by Dahl? and Can the EIU'sdemocracy index be modified by a) internal adjustments and b) using the variables includedin World Economic Forum?s (WEF) equality index?By using a combination of theories (Dahl?s theory of democracy, Rawls theory of justice andchosen theories critical to liberal democracy) as an analytical framework the following twoquestions have been answered:1) Which of the variables included in the EIU's democracy index have the potential to capturethe level of political equality?2) Which of the variables included in the WEF?s equality index have the potential to capturethe degree of political equality?By using a quantitative method the study?s third and last question has been answered:3) How strong is the rank correlation between the EIU?s democracy index and the WEF?sequality index, that is; how strong is the rank correlation coefficient (rho)?The data presented by the WEF?s equality index indicate that women are systematicallydiscriminated against as a group. From a democratic perspective the EIU may need tomeasure inequalities at a group level in order to capture the lack of political equality betweenindividuals. By reformulating some of the EIU?s variables, by revising the EIU?s point systemand by using the variables included in the WEF's equality index to extend EIU?s democracyindex, the chances of capturing the gap between reality and the ideal of democracy presentedby Dahl would likely increase..

Håll ögat på detaljhandeln

This study examines retail atmospherics from a reality perspective. The topic "special exposure" has received research interest in the past but it has not been recognized as a critical consideration in the daily retail business. Too many retailers leave assortment decisions to thumb rules or trial and error. The highest aim of this study is in addressing that gap between theory and practice. To catch the attention of the customer is important in supermarkets because most grocery purchase decisions are made at the point of purchase.
