Effektivisering av Magic Formula Investing : En studie över investeringsstrategier på den svenska aktiemarknaden

I studien behandlas värdeinvesteringsstrategier på den svenska aktiemarknaden med utgångspunkt i Greenblatts (2006) Magic Formula Investing. Syftet med studien är att se om det är möjligt att effektivisera Magic Formula Investing med hjälp av fundamentala signaler som kan hjälpa till att prognostisera bolags framtida vinster och aktieavkastning och därmed nå en högre onormal avkastning. Från Piotroskis (2000) vetenskapligt beprövade investeringsmodell F_SCORE används nyckeltal för att se om en effektivisering av Magic Formula Investing är möjlig. Studiens resultat visar att en utvecklad Magic Formula Investing med Piotroskis (2000) B/M och ACCRUAL kan hjälpa investerare att nå en ökad onormal avkastning med i genomsnitt 10 % per år. Resultatet uppnår statistisk signifikans och därmed dras slutsatsen att en effektivisering av Magic Formula Investing på den svenska marknaden är möjlig.

Prognoser av räntabilitet på eget kapital - En studie av hur Re-prognoser påverkas vid en uppdelning av hävstångsformelns komponenter

Forecasting is an important part in attempting to predict how companies will perform in the future. The more accurate the prediction, the more valuable are the results obtained from the forecast. This thesis aims to investigate forecasts of return on equity, and whether a disaggregation of the leverage formula into its underlying components affects the forecasting ability positively. This is conducted by comparing a model based on the leverage formula's components with a model solely based on return on equity from previous years. The study includes manufacturing companies on the Swedish Stock Exchange over the period 1998-2011.

En komparativ studie av två matematikböcker i årskurs 6 med avseende på elever i matematiksvårigheter

Arbetet syftar till att belysa på vilket eller vilka sätt två läroböcker i matematik för årskurs 6 svarar mot de behov som finns hos elever i matematiksvårigheter. Metoden som används är huvudsakligen kvalitativ i form av intervjuer med lärare och elever. Dessutom har de två läromedlen Matematikboken och Formula analyserats och utvärderats till innehåll och form samt arbetsätt. Den strukturella analysen visar att Formula har fler textuppgifter, medan Matematikboken har fler bilder och förklaringar. Den kvalitativa analysen visar på en närmare koppling till konkreta människo- och miljöaspekter i Matematikboken, medan Formula har sin tyngdpunkt i att guida laborativt elevarbete på egen hand. Lärarintervjuerna visar att valet av läromedel påverkar hur lektionerna läggs upp och strukturen i desamma. Intervjuerna med elever visar att läroboksvalet påverkar deras syn på vad matematik är och hur de arbetar med och förstår matematik. Arbetet har en relevans för arbetet med att stödja elever i matematiksvårigheter..

CarEye ? Sees & Saves:    Fordonskamera för skadedokumentering

In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.

?-funktionenEn kort introduktion

Syftet med denna studie var att synliggöra förskollärares tankar om vardagsmatematiken. Studien skulle även innefatta hur förskollärare tar tillvara på den vardagliga matematiken. Vår metod i studien gick ut på att intervjua förskollärare genom en self report, som tillhör den kvalitativa forskningen. Vår self report innebar att de tillfrågade förskollärarna skriftligt fick redogöra sina tankar och erfarenheter utifrån frågeformuläret. Med hjälp av vår self reports öppna frågor synliggjordes förskollärares djupgående tankar om ett visst fenomen, vilket leder in vår studie till en fenomenografisk forskningsansats.

Mekanisk integration av en IR-detektor i en Stirlingkylare

The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.

Vilken nutritionsbehandling har bäst effekt på tillväxten hos barn födda för tidigt och/eller med låg födelsevikt?

Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: ?What nutrition therapy has the best outcome on growth in preterm children and/or children born with low birth weight??Author: Josefine Nyström and Rebecca HammarSupervisor: Fredrik BertzExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2013Background: There is a number of reasons why a child is born preterm and with a low birth weight, for instance if the mother is underweight, smoking or exposed for malaria. The negative consequences of being born preterm or with a low birth weigth are many, both on long and short term. According to the WHO preterm birth is the most common direct cause of infant mortality. By providing the right measures in time when it comes to nutrition the mortality can be reduced considerably.Objective: To examine and summarise the scientific ground when it comes to the best nutrition therapy for preterm children and children born with a low birth weight.Search strategy: A systematic literature search was done in the databases Pubmed, Cohrane and Scopus.

SAMVERKAN STÅL/BETONG : Kontroll av kapacitet hos blockankare i Connector Samverkansbalk

In April 2007 we contacted Lennart Augustsson at Designpartners AB in Västerås. He came up with the idea to investigate and evaluate their construction of a interaction beam, CSB-beam. CSB is short for Connector Interaction beam. The beam is based on a horizontal C-profile of high-tensile steel and in the bottom of the profile are vertical flat bar welded so called block connectors. These block anchorsare also made of hightensilesteel.

Together we can rock´n´roll : Status Quo- en studie av ett rockbands karriär

The main purpose of this essay is on one hand to try to find and explain the formula of success of the rock group Status Quo, and on the other to elucidate and explain the foundation and essence in the music made by Status Quo, but also to study how, if and why the foundation and essence have changed over the years. The method of investigation is partly based on a musical analysis of three albums from three different periods: Hello! (1973), Ain´t Complaining (1988) and Heavy Traffic (2002), and partly on a sociological study of the group?s career between 1962 and today, 2005.The first part of the essay concerns the period between 1962-1973 with an analysis of the album Hello!; the second part concerns the period 1974-1988 and the album Ain´t Complaining; finally, the third part concerns the years between 1989-2002 with an intensified analysis of the album Heavy Traffic. In the forth part of the essay I discuss the career of Status Quo from a sociological point of view.I run to the conclusion that the essence of Status Quo is the boogie-woogie comp on Fender guitar by Rick Parfitt, the riff on Francis Rossis´ Fender guitar in combination with the base, the piano and the drums. This has been the essence through all the years, even though it was more difficult to apprehend it during the 1980s.

Landsortsdeckare - den nya hembygdslitteraturen? : Analys av tre deckarserier från Sandhamn, Kiruna och Öland

During the last years the number of Swedish detective stories which take place in the province outside the big cities has increased enormously. In this study I have analysed the novels by the three authors Viveca Sten, Åsa Larsson and Johan Theorin to investigate the connection between the milieu and the story and in what way it is involved in the crime riddle.They all keep to the formula of the classical detective story but represent different variations within this formula. In spite of the differences in their stories the basic pattern is the same. As their protagonists the authors are emotionally connected to the place in the novels. This connection it strengthen by the authors themselves as well as the publishing companies when introducing them on the market.

Capacity studies on DeLavals sort gate DSG10

In the dairy production it is necessary to be able to sort cows. Dairy cows are sorted for many different reasons i.e. regrouping into production strings or for treatments i.e. inseminations, pregnancy and health checks, vaccinations or hoof trimmings. One labour saving way of conducting sorting is by using an automatic sort gate.

Vätskebehandling inom brännskadevård

SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.

Effektiv partiformning : analys och tillämpning på Uppåkra Mekaniska AB

This paper is the result of a case study conducted at Uppåkra Mekaniska AB during the spring of 2006. The task that was presented by Uppåkra was to develop a basis for a decision for the planning activities at the company, so that in the future they can create lot-sizes which are based upon a total cost perspective. Total cost in regards to lot-sizing is defined as the sum of the administrative reordering costs and warehousing cost per stock keeping unit.To collect data a series of interviews and observations were conducted. This data was then used during the lot-sizing simulation and analysis. The 15 units that the simulation was conducted on were grouped into three item classes depending how many different machine setups they required during the production process.
