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.

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.

Den lokala morgontidningens annonsavdelning idag och för 15 år sedan : En undersökning baserad på intervjuer av representanter vid sex lokala morgontidningar

During the last 15 years the Swedish media market has developed a great deal, thanks to the rise of new media. Literature, articles and investigations have contributed to producing the chapter of background of this essay. How the local newspaper and its organization has changed over time is being accounted in this essay. From the newspaper being the only product on the market to now having a spread out product portfolio. By doing the qualitative interview with research representatives of six local newspapers the aimis to answer the following questions: Who were your competitors 15 years ago? Who are your competitiors today? In what way has the increased competition changed your way of working at the division of advertisement and how do you consider the the increase of mediachannels having affected the customer? How do you see the future? The main results show that all six representatives agree on the fact that the competition has increased during the last 15 years.

Modellbaserad prediktiv reglering av en dieselmotor med variabel geometriturbin och återcirkulering av avgaser

Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.

Value creation- How can companies optimize the human capital

The thesis aims to examine how companies optimize the human capital from a value creation perspective. The value creation will be related to transfer of knowledge, recruitment, staff turnover and development. The thesis has a deductive approach and six qualitative interviews have been conducted. The results from the interviews will be strengthened with a quantitative data analysis of two measurements; value added per employee and human capital efficiency. The theoretical framework includes definitions of human capital.

Optimering av indunstningsprocess

The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.

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.

Viktoptimering av ett kompositchassi till en multimodal lättviktsfarkost

This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.

Optimering av sintrade kugghjul

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

??Finns det ett samband mellan graden av periodiseringar och inflationsjusterade skattade framtida rörelseresultat? : - Empirisk studie av den europeiska aktiemarknaden.

In line with Sloan (1996) but on European data (STOXX 600) we are investigating whether stock prices reflect information about future earnings contained in the accrual and cash flow components. The extent to which current earnings performance persists into the future earnings performance is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. Moreover, we still find a significant positive excess return (Jensen?s alpha and size-adjusted return) by replicating Sloans (1996) hedge portfolio by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals. However, we find no evidence of negative excess returns for companies with relatively high accruals, this somewhat lower the total excess returns for all the portfolios.

Aktieindexobligationer : För vem är aktieindexobligationer en passande investering?

Bakgrund: Sedan introduktionen i början av 1990-talet har utvecklingen av volymen nyemitterade aktieindexobligationerna totalt sett varit positiv vilket tyder på att produkten blivit en populär sparform hos svenskar. Detta tillsammans med det faktum att det finns få studier gjorda kring aktieindexobligationer som sparform där ett större perspektiv tas i beaktande gör ämnet intressant att studera.Syfte: Uppsatsens syfte är att kartlägga och analysera för vilka privata investerare aktieindexobligationer passar som sparform ur ett livscykelperspektiv med utgångspunkt i (i) bransch- och rådgivningspraxis, (ii) finansiell riskhanteringsteori med fokus på portföljvalsteori och (iii) historisk data avseende risk och avkastning.Genomförande: Studien har genomförts med hjälp av att intervjua privatrådgivare, kapitalrådgivare och personer som arbetar med strukturerade produkter på storbanker och hos mindre finansiella aktörer. Fem stereotyper har använts som diskussionsunderlag vid intervjuerna. För att kunna föra en djupare analys kring produkten som sparform för privata investerare har en portföljoptimering genomförts för att ta historisk data gällande risk och avkastning i beaktande.Slutsats: Studien fastställer att produkten passar privata investerare som befinner sig i den senare delen av konsolideringsfasen och inte är de mest riskbenägna. Studien visar att det främst är kredit- och marknadsrisken som är kopplade till aktieindexobligationer samtidigt som risken i produkten bedöms som låg.
