In 1996, Robert A. Haugen and Nardin L. Baker published a study where they had made a multi-factor model based on micro-variables on the American stock market between 1979 and 1993. In testing the model on the examined period they made an average annual return of 30,9 percent. They also tested the model on several other markets around the world with similar results. This study is a somewhat simple

The aim of the paper is to time the stock market by using probit modelling. We will accomplish this task by testing the significance of different financial variables. The yield spread, which has already been proved to be effective for several established markets, will play a central role in our analysis. Primarily we will extend the analysis of Liu, Resnick and Shoesmith (2004) to verify whether t

Det är därför av intresse att närmare titta på konsekvenserna av den utr

Populärvetenskaplig sammanfattning: Bekämpningsmedel; bra för maten, dåligt för vattnet? Att ha tillgång till rent vatten är livsviktigt för människan. Trots detta saknar nästan hälften av jordens invånare tillgång till vatten av hög kvalitet. Eftersom mycket av det vatten vi använder tas upp ur marken, från grundvattnet, så är det viktigt att inte förorena grundvattnet med ämnen som kan vara skadThis bachelor thesis, written at the Department of Earth and Ecosystem Sciences at Lund University in 2010, discusses the movement of pesticides in the ground. The aim of the study is to examine the potential impact that the ground properties have on the movement of pesticides to and with groundwater. The ground properties that will be considered are the hydraulic conductivity and the depth of the

Purpose: The aim was to explore what socio-economic benefits could be made out of regional networks in an economic, environmental and social perspective. The project also aimed to investigate where there is potential for regional networks and utilization of waste heat, and what barriers exist. In order to investigate the gains that can be achieved two different models was created and then compared

The theory of the Investment Development Path (IDP) by John H. Dunning suggests that as a country develops, its composition of inward and outward foreign direct investment change both regarding to quantity and type of investment.

Populärvetenskaplig sammanfattning: Temperaturdata från de senaste 157 åren visar att jorden genomgår en uppvärmning. Forskare runt om i världen är eniga om att den globala medeltemperaturen även kommer att fortsätta öka de närmsta 100 åren. Dock är temperaturförändringen inte jämt fördelad över jordklotet; den arktiska regionen tros stå inför en snabbare och mer intensiv uppvärmning. Den arktiskaAccording to temperature data for the past 157 years, the global mean temperature is increas-ing with an accelerating rate in the end of the 20th century. Climate models that have been developed on research centers around the world all show a warming trend the next coming 100 years. They also show that the increase in temperature will occur earlier and be more in-tense over the Arctic region. In t

Large eddy simulations of full geometry wind turbines, employing the virtual boundary method, have been carried out with the in-house developed CFD-code at the Division of Fluid Mechanics. The aim is to study the influence of pitch variation on the wake interaction between two wind turbines, and investigate some of the characteristics related to the performance and reliability of the CFD-code. Suc

Populärvetenskaplig sammanfattning: Drunkningsrisk för skogen? Att mängden vatten i marken är viktig för att granen ska kunna ha så god tillväxt som möjligt är ingen nyhet. Är det för fuktigt drunknar rötterna, på grund av att de inte får en tillräckligt mycket syre. I denna studie har två markberedningsmetoder, högläggning och ingen markberedning, jämförts för att se vilket alternativ som är mestNorway spruce is a coniferous tree with many different fields of application. For an example, they are used as Christmas trees, decoration and as timber or pulpwood. The reason why many foresters in Sweden tend to choose spruce as their main species for plantation is partly because of their fast growth rate and partly because the main products are derived from the actual tree trunks. In the forest
