Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

The rise in prevalence and severity of obesity and related diseases imposes increasing costs on society. The objective of this thesis is to discuss and estimate the possible effects of a so-called fat tax as a tool for minimizing these costs. Two alternatives for differentiation of the value-added tax (VAT) on food are compared. The first alternative is an increase of the VAT levied on food containing saturated fatty acids. The second alternative is a subsidy on fruit and vegetables in the form of a VAT at zero percent, instead of today?s twelve percent.

Exotic small animals that are commonly kept as pets include aquarium fish, cage and aviary birds, rodents, rabbits (Oryctolagus cuniculus), reptiles and amphibians. These different kinds of animals, even species within the same class, may differ markedly from each other regarding physiology and requirements. Although these species are common in both Swedish households and in pet trade, many animal keepers have a lack of knowledge about the origin and requirements of their pets. This is a cause of several health problems seen in animals which are held in captivity. In Sweden, the county administrative boards perform all animal welfare controls.

The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.

The aim of this study is to elucidate the process in which psychology was separated from philosophy and established itself as a distinct academic discipline in Sweden. I argue that the concept of will, as well as the concepts of thinking and emotion, have a lot to tell us about the rise of academic psychology in Sweden. This is done through an analysis of psychology textbooks, encyclopaedia-articles and academic texts on the themes will and psychology, from around 1800 till 1950.Prior to the establishment of the first chair of psychology in Uppsala 1948, the discipline was above all a part of the philosophical discipline. For psychology to become a science of its own, it was crucial to obtain a position among the empirical sciences. It thus had to distance itself from philosophy, and in particular from metaphysics.

Problem: Debatten i media går het i fråga om deltidsanställningarnas vara eller icke vara. Arbetsgivare i detaljhandeln ser det som en kritisk nödvändighet, medan facket ser deltidsarbete som ett uttryck för slentrianmässig personalpolitik. Vi ifrågasätter däremot om det är själva förekomsten av deltidsarbete som är problemet eller om det istället kan vara ledarskapet av deltidsanställda som brister? Det saknas enligt oss ett perspektiv som, istället för att vara ideologiskt eller politiskt färgat, tar sig an deltidsproblematiken på ett konstruktivt sätt. Syfte: Syftet är att analysera och identifiera kritiska faktorer för ledningen av deltidsanställda i detaljhandeln.

The progress in the field of technology is often described as massive and its development has had a great impact on the social development (Vetenskapsrådet, 2012). As a result of the digital evolution, there has been a change in the way customer and company interact (Normann, 2011). The traditional way for players to interact with each other required an interaction human to human (ibid), a mode of interaction that now can be replaced or supplemented by todays technology and often Internet-based solutions (Salomonson et al., 2013). These technological solutions, the technical interaction, are often referred to as self-service systems. These systems enables the customer to carry out the tasks previously performed by the company (Hilton and Hughes, 2013).

Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

This master thesis aims to examine how public libraries in Sweden are practically and ideologically equipped to deal with e-books, outside of the dominant distributor Elib. The study also aims to find out what?s required of the book market and the public libraries to make further progress in the question of e-books. In Sweden e-books are still representing only a small amount of all the library loans and an even smaller amount of the commercial book market.The methodological and theoretical ground for the thesis is Grounded Theory, and the survey is based on interviews with publishers, librarians and distributors.The conclusions of this thesis are that the public libraries lack resources to invest in e-books, and that they also lack in knowledge about the media and its readers. It also exposes that both internal and external collaboration efforts need to be further developed.

The town square is an important public space and is often described as the city´s living room. By creating a lively city center a sense of security is developed among the citizens which makes them wanting to use the town square regardless the time of the day. One important meeting point in Gävle is the centrally located Stortorget, sited between Drottninggatan and Nygatan. The town square went through an extensive renovation followed by both positive and negative reactions among the City´s inhabitants.  The aim with the study was to investigate the main walking paths and meeting points as a planning support to Gävle Municipality in their work with a new city plan. By studying the pedestrian movement patterns at Stortorget, Nygatan and Drottninggatan, the main walking paths and meeting points during all hours of the day was obtained.

This essay will examine the historical picture of the island Rapa Nui as it is portrayed in popular science and in ecohistorical literature of the university of Gothenburg. This historical picture states that the inhabitants of the island cut down a lot of trees in the process of transporting the big and heavy statues, moai, from the quarry to the platforms along the coastline of the island. During this process all trees disappeared and resulted in soil erosion. The cultivation was destroyed and brought hunger to Rapa Nui. The following rivalry for food led to a situation of war followed by a cultural collapse.

This Master thesis is about a postal- and telegraphic building in Eskilstuna, Sweden. The construction methods for the specific building and buildings in general from the same time are described. The purpose of the report is to describe the loads acting on the building and how it has been built and why it has been rebuilt during the years. After this, possibilities of reconstruction and adaptation for today?s demands can be evaluated.

I Sverige har det under en längre tid varit ett varierat kapitalutbud för småföretag. Dessa företag har olika förutsättningar när de ska välja finansieringsform. Småföretagare vill ofta i största mån behålla kontrollen över sitt företag och därför är det viktigt för dessa företag att välja den typ av finansiering som gör att företaget bibehåller självständigheten. Småföretag i Sverige har ofta en allt för svag kapitalbas för att kunna växa och göra nya investeringar. Företagens egna vinstmedel räcker sällan till investeringar och det kan krävas extern finansiering, dock har småföretag ofta svårt att bli beviljade banklån eftersom att de har för lite att lämna som säkerhet.

Problem: Det satsas mycket på internutbildningar inom många företag och det finns en del forskat kring ämnet. Den mesta forskningen berör hur internutbildning bör planeras och genomföras samt vilka positiva egenskaper denna utbildning har. Däremot upplever vi att det finns mindre forskat kring om dessa interna utbildningar faktiskt bidrar till något, om de anställda i praktiken tar till sig utbildningarna och drar nytta av dem i sitt dagliga arbete. Inom forskningen kring internutbildningar har fokus även ökat på de anställdas (inom serviceföretag) estetiska attribut såsom utseende och attityd. Syfte: Syftet med vår uppsats är att studera effekten av internutbildningar inom servicebranschen, med fokus på säljpersonal och deras syn på internutbildningar.

Financial bubbles are characterized by a large increase in the economic growth on the market as a whole or in specific industries. The change gives rise to an increase in the capital needed to finance this growth. Companies typically have a choice between equity and debt capital to finance its business and the mix of these types of capital is often referred to as the company?s capital structure. There has been a lot of research done in the field of financial bubbles and ofcapital structure, as of yet no studies seem to address these two areas in combination.The aim of this study is to examine if financial bubbles affect a company?s capital structure and through this also examine if the supposed changes in capital structure can be generalized.The study comprise of two identical time-series which examines the changes in leverage and the choice of financing during the Swedish real estate bubble in the early nineties and the IT-crash at the end of the 2000th century.
