Nordic Marine Sauna AB has, since 2005, designed, manufactured and sold floating saunas. Theproduct are characterised by a well thought thru and appealing design and its high quality. Thecompany is now intending to open a new business area by starting a subsidiary, NordicSubmarine Sauna AB, which will design submerged saunas. The expected customers are leisureand conference centres as well as customers that seek an experience out of the ordinary.Due to the products technical complexity a master thesis was adverted. The task was to do aninvestigation whether such a product is technically viable.The job involved research of existing products and constructions material as well as designingthe product with CAD and FEM-programs.

This report aims to study the condominium prices in central Stockholm and the factors thataffect these prices. A linear regression model was set up and data about relevant covariatessuch as floor area, mortgage rates and where the condominium is situated were gathered toassess if and how they influence the price. The raw data was processed and enhanced to gain asmuch relevant information as possible to the model. To determine the covariates? influence onthe final price, regressions were ran and various tests were performed on the output data.

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.

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

In the 1960?s, Paul Hersey and Ken Blanchard developed a theory called Situational Leadership. Situational Leadership is a model where the leader analyses the needs of the situation and the needs of the people to be led. After analysing the situation, decision is made on what leadership style to adopt. The Situational Leadership model was developed in a company environment.

Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

The purpose of this essay is to state a fundamental model which can describe the sounds of the city, emphasizing on its rhythm. The essay is based on a theoretical study that deals with essential elements to describe a soundscape. The theories presented are founded on R. Murray Schafer's theses about soundscapes, Bert De Coensels theses about rhythmical sound patterns and Ambjörn Hugardts view on rhythm. The model that is presented stresses the importance of a multidisciplinary perspective when one attempts to understand and describe a soundscape.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

I denna uppsats undersöks hur alternativa viktningsmetoder av OMXS30 har presterat mellan 2004-2010. Studien har sin utgångspunkt i teorierna kring Capital Asset Pricing Model och Effektiva Marknadshypotesen. Syftet med studien är att undersöka huruvida ett kapitalviktat index är effektivt i enlighet med dessa teorier. I studien konstrueras fem stycken index, ett kapitalviktat, två fundamentalviktade, ett riskviktat och ett kombinationsviktat index. För att avgöra indexens historiska prestation analyseras de utifrån utvärderingsmått som mäter riskjusterad avkastning.

Prostitution has for a long time been an understudied field in economics. Due in part to a lack of quantitative and empirical material, itself largely a result of the illegality or semi-illegality of the activity in most countries, the factors that explain the prevalence of, and pricing in, prostitution have remained largely undiscussed. In the last 20 year, this have begun to change: new theories ? notably by Edlund & Korn (2002), Rao et al (2003) and Della Giusta et al (2009) ? have been formulated and the rise of internet based escort sites have made large scale quantitative studies possible. This thesis examines if, and in what way, court documents can help expand the understanding of the economics of prostitution in Sweden.

Transfer pricing innebär i grund och botten att den vinst som företagsgrupper får ska fördelas på ett korrekt sätt mellan deländer där gruppen har aktörer.Armlängdsprincipen är den internationellt accepterade tillvägagångssättet att fastställa priser när närstående företag handlar medvarandra. Principen innebär att företagen ska handla med varandra precis som om de vore oberoende företag, påarmlängdsavstånd.Immateriella tillgångar har en rad egenskaper som gör dem speciellt svårvärderade ur armlängdsperspektiv. Marknadsvärdetbehöver inte vara samma som värdet för ägaren. I regel finns det heller inga transaktioner som innefattar immateriella tillgångarvilket gör det svårt att få en lämplig armlängdsvärdering med hjälp av de tre traditionella metoderna.De två vinstbaserade metoderna (Profit Split Method och Transactional Net Margin Method) är de mest lämpliga för atttillgodose armlängdsprincipen. Profit Split Method:s kanske största fördel är att man för att använda metoden inte behöver hajämförbara transaktioner till hands.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.

Those who have invested in apartments, i.e. tenant-ownership, within the city centre of Stockholm have gained a higher than expected return on investment due to a buoyant real estate market. During the latest twelve-month period, the prices have risen more than 20 per cent in the city of Stockholm, resulting in an increased wealth together with a higher debt burden among investors. The aim of this thesis is to investigate which factors determine the prices from a micro perspective, and to what extent. An attempt is particularly made to estimate the degree of capitalization of the monthly fees; a factor which has turned out to be important according to other studies; but also to construct pricing models in order to set target prices for apartments.

Syfte: Syftet med den här uppsatsen är att undersöka läkemedelsföretag för att sedan jämföra läkemedelsbranschen med stockholmsbörsen för att se hur läkemedelsbranschen påverkats av finanskrisen på slutet av 2000-talet.Metod: Studien bygger på en hypotesprövning och författarna har valt att använda en deduktiv ansats och en kvantitativ datainsamlingsmetod för att samla in data kring läkemedelsaktier.Teori: Studiens analyser bygger på två teoretiska modeller. Den ena är CAPM (Capital Asset Pricing Model) som är en modell som används för att räkna fram avkastningskravet för aktieägarna. Det andra är ett teorem (Modigliani-Millers) avseende kapitalstruktur och som behandlar marknadsvärdet på ettbolag oberoende av finansieringsform eller distribution av utdelningar.Empiri: Jämförelser mellan Stockholmsbörsens generalindex och de fem största läkemedelsbolagen visar på att läkemedelsbolagen delvis följer börsens utveckling. Men över tid så visar sig läkemedelsaktierna vara stabilare och återhämtar sig snabbare än börsen som helhet.Slutsats: Till en början kan man se att finanskrisen har påverkat hela börsen inklusive läkemedelsbranschen. Dock visar en närmare observation av händelsen att läkemedelsaktierna återhämtar sig betydligt fortare och att de totalt sett inte svänger lika mycket..
