Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Medborgarnas Förtroende för EU : En fråga om gemensam europeisk identitet?

Den Europeiska Unionen är en mångfacetterad samling länder med ett brett spektra av historisk bakgrund, geografisk placering och ekonomiska förhållanden. I denna uppsats undersöks huruvida en gemensam europeisk identitet kan bidra till en ökad tillit från medborgarna i unionen till EU som institution.Uppsatsens teoretiska underlag består av tidigare forskning. Denna forskning skapar ett fundament för den statistiska modell som används för att besvara frågeställningen.Med hjälp av data samlad ur bland annat Eurobarometerrapporter tar uppsatsen, via multipel linjär regression, fram en modell som förklarar förhållandet mellan den beroende variabeln ?förtroende för EU? och de oberoende variablerna ?uppfattning av gemensam europeisk identitet?, ?avstånd till Bryssel?, ?BNP per capita? och ?antal år som medlem i EU?.Resultatet visar en koppling mellan en högre grad av upplevd gemensam identitet hos medborgarna i ett land och ett ökat förtroende för EU.Vidare visar modellen ett negativt samband mellan förtroendet för EU och ett stigande värde på var och en av de övriga förklaringsvariablerna. Med andra ord: ju längre avstånd till Bryssel, ju högre BNP per capita och ju längre medlemskap i unionen desto lägre förtroende känner den genomsnittlige medborgaren för EU..

Inkrementell responsanalys : Vilka kunder bör väljas vid riktad marknadsföring?

If customers respond differently to a campaign, it is worthwhile to find those customers who respond most positively and direct the campaign towards them. This can be done by using so called incremental response analysis where respondents from a campaign are compared with respondents from a control group. Customers with the highest increased response from the campaign will be selected and thus may increase the company?s return. Incremental response analysis is applied to the mobile operator Tres historical data.

DEN EKONOMISKA EFFEKTEN AV ÖVERKLAGANDEN I GÖTEBORG - Kan överklaganden mot bostadsbyggnadsprojekt härledas till demografiska faktorer och vilka ekonomiska effekter kan de ge för byggföretagen?

This bachelor thesis addresses the problem of appeals against house building in Gothenburg. The thesis investigates whether there is a statistically significant relationship between demographic factors and the occurrence of approved, appealed and revoked permits for new construction of residential buildings in the ten districts of Gothenburg. This is done with a correlation analysis. The report also investigates whether there is a statistically significant regression in the same demographic factors and how these individually affect the average processing time for appeals in the districts. This study is done with a Multiple regression analysis.

Analys av bortfall i en uppföljningsundersökning av hälsa

The LSH-study started in 2003 at the department of Health and Society at the University of Linköping. The purpose of the study was to examine the relationship between life condition, stress and health. A total of 1007 people from ten different health centres in Östergötlands län participated. At the follow up, a couple of years later, 795 of the 1007 participated. 127 of the 212 in the attrition turned down the follow up, twelve people were not invited (for example in case of death) and the rest did not respond at all.

Identifiering av röjningsbestånd med hjälp av flygburen laserskanning

Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.

Identifiering och redovisning av immateriella tillgångar vid rörelseförvärv ?En kvantitativ studie om redovisningstransparens och kapitalmarknadens informationsasymmetri

The association between disclosure level and asymmetric information is a matter of importance andconsiderable interest to the financial reporting community. The theory in this area suggests that acommitment by a firm to increased levels of disclosure should lower the information asymmetry thuslowering the cost of equity. This theory may be compelling, but so far the empirical results have beenambiguous. Due to increased globalization the demand for high quality accounting standards has risen. In2005 The International Accounting Standard Board launched the standard named IFRS 3.

Modeling Determinants of First-Day Returns from IPOs

The primary purpose of this paper is to find the determinants of first-day returns on the Stockholm Stock Exchange. Our research will cover the 1996 ? 2004 periods. Our secondary purpose is intended to find a profitable trading strategy with regard to future IPOs on the Stockholm Stock Exchange. By using regression analysis, focusing on company specific factors and the IPO process, we hope to find a function exhibiting statistical significance, determining future first-day returns from which construction of a profitable trading strategy will be possible.

DEHP - från mjukgörare till hormonstörande

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Matrismodellen vs Two-part regressionsmodeller - effekter på Region Skånes resursfördelning

An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.

Utveckling och utvördering av statistiska metoder för att öka träffsäkerheten hos lokala vindprognoser

Wind is used as an energy source all over the world. To be able to use this effectively, there is a need for as good forecasts and forecast models as possible. One of these models is Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®) that is used to calculate short time forecasts. This model is used here to calculate wind speeds at two different areas in Västra Götaland, Bengtsfors and Vänersborg. There are also wind measurements with SODAR stations for these areas.
