Multipel regressionsanalys av variabler som paverkar BNP
In this report a model was constructed in order to determine how a number of covariates influence the gross domestic product, GDP. The covariates were chosen depending on their expected influence on GDP, for example education and life expectancy. The data used in this report are collected from the World Bank. The model to describe GDP has been calculated using multiple line arregression. In order to reach a reliable final model the number of covariates has been gradually decreased to eliminate insignificant covariates.
Att skapa en lyckad aktieportfölj : En komparativ uppsats om aktieportföljer och dess faktorer i den svenska marknaden
Syfte: En komparativ studie och beskriva möjligheterna för att skapa en effektiv portfölj av olika aktieportföljer, där det undersöks om faktorerna som företagens omsättningsstorlek, branschen de är aktiva i och valet att ha utländska aktier, har betydelse eller inte för att skapa en effektiv portfölj med hänsyn till dess korrelation, avkastning och risk. Metod: Uppsatsen utgår från en kvantitativ studie, som sträcker sig från april 2008 till april 2010, då historiska aktiekurspriser används för olika sorters uträkningar, som baseras på uppsatsens huvudteorier; CAPM, Sharpekvot och portföljteori. Utgångspunkten är deduktiv, där slutsatserna har dragits från teorierna. Slutsats: Utifrån uträkningarna, kunde det inte dras generella slutsatser där de undersökta faktorerna inte utmärkte sig i något mönster. Däremot visade sig att det blev högre avkastning till liknande risk eller lägre risk till liknade avkastning när man väljer aktier som är olika varandra, då korrelationen inte samvarierar. Det bästa resultatet är när utländska aktier blandas in i portföljen. .
Hudiksvalls samordningsmodell- en modell för att underlätta samverkan?
AbstractHudiksvalls coordinating model - a model to make cooperation easierCamilla Andersson and Åsa GradinThe purpose of this study was to examine the experience each one of the administrators have of their own new model in Hudiksvall to make cooperation easier for the three different administrations in Hudiksvalls municipality. The study will focus on the administrators experiences of Hudiksvalls coordinating design. Questions of the study were: How is the influence of the model on the rules? How is the influence of the model on expectations and parts? What kind of influence did the model have on the responsibility distribution? What kind of influence has the model on the responsibilities at the transfer of costs? To answer the questions of the study we applied a qualitative method, it was made through a standardization interview guide and open questions, with six of the dealing officers who works with the model. Some of the results wich can be discern are by an economic character, andfor the clients that they won`t be passed around the administrations in the community, they get the right help, quick and safe.Key words: cooperation, coordination..
Simulering av filtrerade skärmfärger
This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.
Hur motverkas rasism och främlingsfientlighet? : En undersökning hur två skolor med olika förutsättningar väljer att arbeta med värdegrunden.
AbstractMarie Widerberg (2010). Portfolio i förskolan med perspektiv på specialpedagogik. (Portfolio in primary school with perspective on special education.) Sektionen för lärarutbildningen, specialpedagog utbildningen 90 hp.Examensarbetets syfte är att med perspektiv på specialpedagogik, undersöka hur portfolion används på förskolor i en mindre kommun samt belysa specialpedagogens roll. Undersökningen utgår från följande frågeställningar: På vilket sätt påverkar och utvecklar portfolion enligt pedagogerna, det enskilda barnet och förskolans verksamhet? På vilka sätt används portfolio som ett underlag till pedagogernas egen reflektion kring sin verksamhet och sitt förhållningssätt? Vilka möjligheter och hinder menar pedagogerna att det finns i arbetet med portfolio? samt Vilken roll kan specialpedagogen ha i arbetet med portfolio och hur kan portfolion användas som ett specialpedagogiskt redskap? Arbetet ger en översikt av tidigare forskning om portfolio, specialpedagogik samt specialpedagogens roll i förskolan.
Modellering av rotationssystem
This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.
Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data
A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..
Den moderna kommunikationen : En rapport om instant messaging och hur det används av unga vuxna studenter.
This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.
Kommunikationsstrategi för Renbruksplan : är det en fungerande modell för samebyarna vid samråd?
The reindeer planning system (Renbruksplanen, RBP) is a communication and planning tool designed for Sami groups. A key purpose of this is that it will act as a tool in consultation with other market players, including forestry. Sami groups have asked for a model of how this can be used in a flexible manner. With the Swedish Forest Agency as a project manager, a communication model for how to use the RBP has been designed. It consists of a number of points divided into ?before?, ?during? and ?after? the consultation.
Aktiefonder : Ett lönsamt investeringsalternativ?
Background: Mutual funds have become an important part of the Swedish deposit market. Savings in mutual funds add up to almost 20 percent of the households'assets. When the pension reform is carried out all employees are going to have savings both in mutual and bond funds. But only if the fund overperforms the market it is worth investing. Purpose: The purpose of this study is to explore if Swedish mutual funds have generated higher returns than market portfolio in the late nineties.
På vilka grunder bedöms elevernas insatser under APU:n? : En granskning av det nuvarande bedömningsunderlaget för elevernas APU på Sjömansskolan i Stockholm och ett förslag till bättre bedömningsunderlag med portfolio som hjälpmedel.
Vi har på förslag från Johan Östergren, rektor på Sjömansskolan i Stockholm, kartlagt vad som fungerar bra och vad som fungerar mindre bra med det nuvarande systemet för bedömning av elevernas insatser när de är ute på APU (Arbetsplatsförlagd utbildning). Genom att intervjua elever, handledare, lärare och rektor, har vi bland annat undersökt hur kommunikationen mellan grupperna ser ut och vad de olika grupperna anser om de nuvarande dokumenten som eleverna arbetar med under APU:n. När elevens APU är slut ska handledaren lämna en betygsrekommendation till läraren, men på vilka grunder görs denna bedömning? Vi gör en historisk återblick för att ge läsaren förståelse för den yrkeskultur och tradition som finns inom sjömansyrket. Den svenska sjömansutbildningen jämförs i ett internationellt perspektiv med den lärlingsanpassade sjömansutbildningen i Danmark.

A Strategic Decision-Making Model for Supply Chain - A Void to be Filled
Many researchers emphasize the increasing strategic importance of supply chain management, but there is still a lack of concrete guidance for managers faced with strategic decisions in supply chain. Within decision-making theories, the rational decision-making model is the most commonly used. This because of its suitable foundation, enabling a structure to the complex decision process. The rational decision-making model is today not developed to include the aspects of strategic decision-making made in supply chain. The purpose of this research is to adjust a structured rational decision-making model, making it applicable for strategic decision-making in supply chain.
Dynamisk modellering av VSC-HVDC : En statisk och dynamisk modelldesign o?ver VSC-HVDC fo?r implementering i ARISTO
This thesis treats the subject of a complete steady state and dynamic model of the VSC-HVDC covering both the AC and DC system-side of the converter. The topology of the model is recreated after the scheduled transmission line in the south of Sweden, called SydVa?stla?nken. The topology covers both a simple two terminal connection as well as a multi-terminal one. This model is to be implemented in the power system simulation program ARISTO.
Yrkesrelevant Gymnasiearbete på El- och Energiprogrammet
The purpose of this development project is to create a model for working with a high school project in Electrical and Energy Program. It should be conducted in a form like companies do according to the goals from The Swedish National Agency for Education. In order to fully perform this we use the concept of Young Entrepreneurship. The model is created according to the new conditions from The National Electrical Safety Board. There is now an exception saying that a student during education is released from the demand of employment that is the normal procedure where you are under supervision from a certified electrician. During the project there has been theoretical and practical examinations in order to clear out the advantages and disadvantages using this model, but also to examine whether it is useful in the future and to what extent it can be used. The result indicates that the model is useful and fulfills the goals from The Swedish National Agency for Education but that the model has its limitations and difficulties.
