Demokrati : En studie om demokratiindex och dess eventuella begränsningar
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..
Re-Load lastpall : En jämförelse mellan Re-Load och alternativ lastpall
Syftet med denna undersökning har varit att underlätta för företaget Re-Load att presentera sin lastpall som produkt för potentiella kunder. Syftet har också varit att stötta Re-Load till att bli licenserad EUR-pall samt att successivt ersätta befintliga lastpallar och långsiktigt exekvera företagets affärsplan. Målet har varit att undersöka produkten avseende lönsamhet, miljöinverkan och hur den påverkade arbetsmiljön. Under-sökningen har genomförts med ett befintligt flöde där produkten använts och utifrån detta kunde en flödesstudie samt en komparativ produktstudie utföras med en alternativ lastpall. Med data hämtat ur detta flöde utfördes en investeringskalkylering, miljöberäkningar, subjektiva intervjuer samt dokumentation.
The Value of Digital Information DIV-index, A Corporate Asset
Companies have in the past decades changed fromtraditional manufacturing organizations into serviceorganizations. For these service organizationsinformation and competence have become animportant resource. The traditional view oninformation is that an employee use and search forinformation to reduce uncertainty for their decisionmaking. Even though information is strategicallyimportant for organizations, information is not valuedin any way. Hence, this thesis aims to valueinformation in terms of the utility it brings to theorganization.The conclusion is that four factors are important whenvaluing information in terms of utility.
Optimering av multiprocessorsystem med hjälp av schemaläggning
A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.
Aktieindexobligationer : Småspararens Livbåt på Vägen mot Djupt Vatten?
The main purpose of the essay was to evaluate whether investments in index-linked bonds were suitable investments for smaller investors on the international finance market. To determine whether the index-linked bonds are good investments, the variables yield, cost and risk were used to measure the index-linked bonds against investments in stocks and funds. The reason for the interest in this subject is that investments in index-linked bonds have grown furiously the last few years. With the growth of the investments the criticism of index-linked bonds has also grown stronger. The critics? main point is the cost of the product, and they imply that investors can create their own index-linked bond and thereby avoid the bank fees.This study used a quantitative approach, because all the data of yield, cost and risk consist of numbers.
Fundamental indexering - fundamentalt rätt?? : En studie av den svenska aktiemarknaden
I denna undersökning konstrueras fundamentala aktieindex med aktier innefattade av indexetStockholm OMX30 under perioden 1999-04-01 till och med 2009-03-31. Dels konstruerasenskilda index där indexeringen sker efter faktorerna bokvärde, utdelning, försäljning, resultat,kassaflöde och antal anställda, dels ett index där faktorerna sammanvägs. Detta för att undersökahuruvida fundamentala index bättre speglar företags fundamentala värde och därmed genererarhögre riskjusterad avkastning i förhållande till ett marknadsvägt referensindex. De enskildaindexen bokvärde, utdelning, försäljning, antal anställda samt det sammanvägda indexet visarhögre riskjusterad avkastning än referensindexet. Kassaflödes- och resultatindexet presterardäremot markant sämre än referensindexet.
Siktning som saneringsmetod för metallförorenad mark
Toxic metals contaminate soil worldwide and thus serve as sever environmental threat. Therefore the purposes of this study were to investigate in which soil fractions that different heavy metals (Fe, As, Cu, Zn and Pb) could be found in contaminated soils and if it is possible to use sieving as a method for decontamination. Soil samples were collected from three different locations, the Nasa silver mine, the Blaiken-mine and Svalget environmental station. The samples were oven dried and later on sieved into six different fractions 8mm, 4 mm, 0.5 mm, 0.250mm, 0.063 mm and <0.063 mm. The fractions 4 mm, 0.5 mm and <0.063 mm from each location were analyzed in an x-ray fluorescence detector.
Utveckling av lastmodell för Uppsala fjärrvärmenät
The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.
Finns det någon list med digitala tavlor? : En kvalitativ studie av översiktstavlor inom agila projekt och förutsättningar för digitala sådana
This paper is about the use of task boards in agile system development projects. The main focus is on how digitalized versions of the task board can be of assistance during the development process. Our investigation is based on qualitative studies, with system developers of various backgrounds and professional roles, along with studies of relevant literature. The main results are that a digitized version of the task board can increase awareness for the team and be of major importance if it is accessible through the web. On the other hand negative effects of the digitalization can emerge as well.
