Den rapport du just ska till att läsa är ett kandidatarbete i matematisk statistik skrivet vid matematiska instutitionen, Linköpings Universitet. Det område som undersöks är att om man med hjälp av P/E-tal kan förutsäga kraftiga börsnedgångar (börskrascher) på OMXS30. För att definiera en börskrasch har vi använt måttet Value at Risk (VaR). Detta mått är vedertaget hos finansiella instutitioner som ett riskmått men i denna rapport används det som sagt för att definiera nivån for en börskrasch. VaR har beräknats med diverse olika metoder som presenteras i rapporten.   Efter att en börskrasch definierats har vi använt logistisk regression med P/E-tal som förklaringsvariabel för att undersöka om dessa nedgångar har ett samband med höga P/E-tal.

The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.

The work examines geographical variations of bicycle use in Trondheim municipality with the aim to create an understanding of what influences the use of bicycles and explain the geographical travel pattern for cycling. The work focuses on the how physical structures generates different transports effects. Where bicycle travels in Trondheim municipality are undertaken is described by using network analysis in ArcGIS, based on aggregated data from the travel habit survey (RVU) in 2009/2010. Trondheim municipality is divided into smaller geographical units (zoner) whose characteristics are described by 19 variables, categorized into 6 groups; Distance, Land use, Topography, Bicycle Facilities, Road characteristics and Demographic factors.By linear regression analysis in SPSS and ArcGIS Spatial Analyst, an explanatory model is elaborated. The variablesdistance to the regional center, workplace density, percentage separate bike paths and hilly terrain explains 78 percent of where cycle journeys are undertaken.

The purpose with this thesis is to analyse different factors that can explain district heating prices for energy companies in Sweden. We are further interested in examining if the prices is affected by the use of industrial waste heat in their production and the company?s ownership structure. The method applied is a multiple regression analysis using a panel data set of 50 companies over 5 years (2008-2012). The data used is yearly data obtained from the Swedish district heating association.

Background: The relation between work motivation and well-being are relatively well theoretically entrenched, but few studies have been conducted on nurses within psychiatry. Objective: The aim of the present study was to examine the differences in intrinsic work motivation (autonomy, competence, relatedness), mental health and burnout between young (?40 years) and older (>40 years) nurses employed in psychiatry. Method: The study was an observational study with a cross-sectional design and group comparisons, conducted as a survey. The sample constituted of 60 employed nurses.

The study - Hur skapas en journalist? - examines why so many people choose to turn tothe journalist profession when the conditions for a secure position on the labor market ispoor. The study also highlights how recently graduated journalist perceives their temporary and insecure position on the labor market.The study was performed trough ten biographical interviews with recently graduated journalists. Via the interviews I examined what has formed the individuals to perceive journalism as a rational or pragmatic choice for a career. The study shows that journalists, who come from families with high cultural capital, have been shaped by a particular culture of education, which focuses on education as a step towards selfrealization.

The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.

 I denna rapport undersöks hur ett antal kundspecifika faktorer som belåningrad, bank och inkomst påverkar svenska hushålls individuella bolåneräntor. Metoden som används är multipel linjär regression med transformeringar av förklarande variabler. Transformer som används är log-linjär, linjär-log, log-log samt styckvis linjär. Datan innehåller ett stickprov om ca. 7000 rörliga bolån från juli 2013 insamlade av organisationen Villaägarna på frivillig basis.

In this essay I analyze the way my collection of poetry relates to the concept cyclic. What is cyclic and what different interpretations are there concerning the concept? Which other related concepts are there regarding things that seem to reoccur regularly? How does the cyclical, the circular, relate to the linear in regard, for example, to the perception of time? Life often creates the sense that different phenomena and experiences repeat themselves. Different processes are conducted according to regular or irregular cyclical phases, situations seem familiar and events can be relived.         Starting from my writing project Sinnligt kviller, a collection of poems, I discuss these questions in themselves and the impact they have had on my collection. I describe the phenomenon cyclic as a result of the emotions and moods this term creates in a more or less decisive way.         The intention with this paper is to show how Sinnligt kviller offers different perspectives of and reflections upon the various feelings provoked by the cyclic in our lives, feelings that are given my own voice in the literary text under study..

Syftet med uppsatsen är att undersöka huruvida det har skett en förändring i riskaversionen mellan perioden 1980-1995 och 1996-2000. Sambandet mellan risk och värdering undersöks för att ta reda på detta. En kvantitativ metod har använts för att genomföra undersökningen. Statistiska modeller som enkel och multipel regression har använts för att söka samband mellan värdering och risk. Rådata har hämtats ur ?SIX Trust?-databasen och vi har därefter behandlat datan i Excel och SPSS.

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.

In 2022, Russia completed its full-scale invasion of Ukraine. The EU responded with powerful restrictive measures against Russia to demonstrate its unified support for Ukraine, indicating that the perception of Russia as an external threat to the EU, particularly in Central and Eastern Europe (CEE), has become increasingly evident following the invasion. Drawing on theory and previous research suggesting that external threats strengthen group identities, I argue that Russia is perceived as an external threat to EU identity in CEE after Russia's invasion of Ukraine. Stephan and Stephan's integrated threat theory considers an external threat as either realistic, posing a threat to the ingroup's existence, or symbolic, posing a threat to the ingroup's worldview. The purpose of this study is to examine the relationship between EU identity and the perception of Russia as a group threat to the EU among individuals in CEE based on the nature of the group threat: realistic and symbolic.

This study investigates the value relevance of goodwill impairments for equity investors in Swedish listed companies. We provide insight on whether goodwill impairments are value relevant before as well as after the implementation of IFRS 3 and IAS 36. We express market value of equity as a function of book value of equity; net income excluding goodwill impairments and goodwill impairments, using the Ohlson valuation model and Hellström's price regression. Our findings suggest that goodwill impairments are statistically value relevant for equity investors. Prior to the implementation of IFRS 3 and IAS 36, our findings imply that equity investors respond negatively to goodwill impairments.

Does the country people live in affect the probability of them experiencing happiness? Can a country variable in an ordinal regression model be affected when microeconomic and macroeconomic factors are added to the model? The possible outcomes are either that the country variable affects less when the additional predictors are added to the model, or that they stay the same. The micro data is collected from the European Social Survey database, the macro data is collected from the World Bank. The country variable becomes less substantial when additional variables are added to the model. The variable with the most influence over expected happiness apart from the country variable is whether the individual often socializes with friends or not.

How do we perceive literature? In our times computer games and Internet have made us grow more comfortable to the usage of non linear storylines. But how does this apply to printed literature?In this essay, called ?From a to b through d h and o. Non linear storytelling in our time? I have focused on nonlinear literature from different time periods and I have studied novels such as James Joyce?s Ulysses as well as works by William S.
