Kan risken för finansiell kris förutsäga första dagens avkastning vid börsintroduktioner?

This thesis studies the relationship between risk and the first day returns of Initial Public Offerings (IPO) by assessing the risk of each issuing company with a risk model that combine financial key ratios of importance. The study is based on 92 IPO?s that were made on the Stockholm OMX stock exchange during the period of 1997-2009. The point of departure was to investigate if the uncertainty created by the asymmetric information between investors and the issuing firm could be captured by predicting the possibility of failure in the future. This has been studied by applying Skogsvik?s probability of failure model on the 92 issuing firms.

Mobiltelefon utformad med EcoDesign

The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.

Virtuell design av en testrigg för ett vindkraftverks drivlina - Analys av vibrationsdynamik

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Crowdfunding : Svenskarnas motiv till att investera

The purpose of this essay is to examine the Swedish people?s level of knowledge about crowdfunding and their incentives and deterrents to crowdfunding investments. Early on crowdfunding was divided into two objectives: reward based and equity based crowdfunding. The division of objectives is logical due to the differencing conditions of the motivation for investors to invest. Supported by theories in crowdfunding incentives, commitment-trust, the prospect theory, and the diffusion of innovations, we aim to establish a comprehensive line of reasoning to support our model of motivation in the conclusive chapter.The results of this essay were achieved by a combined method.

Datormodellering av en värmelagrande betongväggs inverkan på det termiska klimatet i ett växthus

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

Nätnyttomodellens fall och framtidens reglering av eltransmissionstariffer : Tidigare meningsskiljaktigheter samt undersökning av förutsättningar för framtida reglering

The main ambition of this degree project is to illustrate the fundamental problems of today?s electric tariff regulation and the usage of the analyzing tool; The Network Tariff Model. There is a further discussion of potential problems and clear improvements of the 2012 years proposed network tariff regulation. Interviews have been conducted with specific network companies and Energimarknadsinspektionen. The proposed regulation of 2012 is discussed from the government?s proposition.This paper clearly shows that the authority´s work has been conducted in a very unprofessional manner during the period of The Network Tariff Model.

Tillämpning av Component Object Model vid utveckling av webbapplikationer med Active Server Pages

Denna studie undersöker om, och i så fall hur, utvecklingen av webbapplikationer med ASP kan förbättras genom tillämpning av COM-objekt. För att göra detta används fyra jämförelsekriterier som tagits fram utifrån fördelar och nackdelar med ASP respektive COM-objekt. Dessa kriterier avser att jämföra ASP och COM-objekt i exekveringstid av scriptkod, återanvändning av funktionalitet, inkapsling av databasrelaterad kod och prototyputveckling. Det resultat som erhållits av genomförandet visar att utvecklingen av webbapplikationer med ASP kan i olika situationer tillämpa COM-objekt för att: förbättra exekveringstiden av scriptkod, förenkla återanvändningen av funktionalitet och göra ASP-koden mer strukturerad genom att kapsla in databasrelaterad kod. Vad gäller prototyputveckling anses dock ASP vara bättre anpassat, då COM-objekt kräver noggrann planering av gränssnittet och dessutom är beroende av ett testprogram för att kunna testa prototypen..

Aktiva ägares påverkan på svenska börsbolags lönsamhet

This thesis investigates the effects of active ownership on the return on assets (ROA) of Swedish listed companies during the years 2003 to 2013. Active ownership is operationalized based on the probabilistic voting model that is used to calculate the minimum amount of shares the largest shareholder needs in order to possess control of a contested vote at the shareholder meeting. We study the three largest lists on the Nasdaq OMX Stockholm, having 1454 observations from 207 companies to test our hypothesis. The main result from the study is that there's a significant positive relationship between active ownership and ROA during the investigated period. The active owners' relative strength also proves to have a significant positive relationship to ROA..

Prediktion av villapris och dess faktorers inverkan.

 A villas price depends on several important factors. By statistical data, a mathematical multiple regression model was modeled. The model has important explanatory variables such as living space, renovation year and standard points has been taken into consideration, in order to assess their impact on the final price for private homes.By using a statistical program,Minitab 16, the final model was selected with eight explanatory variables. The regression for this model explains up to 67.3 % of the variation on the final price.The results showed percentage wise that the standard points had the greatest impact on the price, there after renovation year and then living space..

Aktiv dödshjälp : en studie de lege lata och de lege ferenda

?Liberal Democracy? is a common term in political theory, and it is used as if it had a commonly accepted referent, with both normative and descriptive content. This is certainly the case in democratic theory, where it on the one hand seems to refer to a normative democratic model; on the other hand it is used descriptively, to refer to real-life democracies. The deliberative democratic sub-field is not an exception; on the contrary, the term is frequently used albeit rarely defined; yet the concept it refers to is supposedly developed enough to allow detailed propositions about its citizens?s political behaviour.This essay is an attempt to analyze how Liberal Democracy is used by three deliberative democrats (Jürgen Habermas, John Dryzek and Stephen Elstub), in order to understand the democratic model (or models), whether normative or descriptive, they refer to.

Mean value modelling of a poppet valve EGR-system

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.
