This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

The aim of this study is to investigate the motivations behind individuals running unpaid fan accounts on social media dedicated to Lady Gaga from a work science perspective. Furthermore, the study critically analyzes the boundary between voluntary engagement and potential labor exploitation. The research questions are: ?What drivers and motivations underlie individuals unpaid management of Lady Gaga fan accounts on social media?? and ?What potential negative consequences or risks may arise for individuals who manage fan accounts on social media without compensation??. The study employs a qualitative method consisting of five semi-structured interviews with fan account owners active on platforms such as TikTok, Instagram, and X.

This paper examines the interpersonal and intercorporate networks of interlocking boardmembers among Sweden's 50 largest publicly traded companies in 1985 and 2005. We find that both the interpersonal and intercorporate networks of 1985 are considerably more coherent and densely connected than those of 2005. The observed changes in social network structure are compared to changes in company ownership in Swedish publicly traded companies during the same period, and it is found that the observed changes in network density and cohesion can be related to a notable increase in the number of foreign board members. These results imply that the social organization of the Swedish system of corporate governance has changed notably during the period. Social network theory suggests that these changes can explain the greater demand for external regulation, decreased homogeneity of board members and increase in board member compensation observed under the period.

The paper contains comment, clarification and criticism, even constructive criticism, of some theses that have been put forward by Laurence Bonjour in his In Defense of Pure Reason.It presents a concept of experience that deals with the relation between cognizer and object of experience that has a great similarity to that of Bonjour. Through analysis it is shown that the concept of a priori entails that Bonjour has two concepts of a priori, a narrow and a broad one. The narrow one is, in my own words: According to moderate rationalism a proposition p is a priori justified if and only if you apprehend that p must be true in every possible world. This doesn?t mean that Bonjour doesn?t believe in an epistemological, metaphysical and semantic realm.

This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management. The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

Hur påverkar högre utbildningsnivå brottslighet? Den här uppsatsen undersöker effekt av eftergymnasial utbildning på våldsbrott respektive stöld-, rån- och häleribrott. Vår första hypotes är att eftergymnasial utbildning har en minskande effekt på våldsbrott genom högre alternativkostnad av brott samt att psykologiska faktorer påverkas positivt. Vår andra hypotes är att eftergymnasial utbildning har en ökande effekt på stöld-, rån- och häleribrott via högre avkastning till följd av mer kunskap för planering och utförande av denna typen av brott. Vidare förmodas en högre utbildningsnivå  generera mer tillgänglig egendom vilket leder till tilltagande incitament för stöld-, rån- och häleribrott.

The single market is one of the underlying ideas of the European Union. Free movement of goods and efficient competition are central for the function of the union and are therefore carefully protected by the Treaty of Rome. Exclusive rights of trademarks in the EU can be seen as a method of dividing the common market, preventing the free movement of goods and to be anti-competitive. What comes out of this is that there is a conflict between exclusive rights of trademarks and the rules of both free movement of goods and competition. The aim of this work is to see in which kind of situations the exclusive rights of trademarks can be a part of this conflict but also to study how this problem is resolved by the European Court.

Problem: Trots att betalkort funnits länge i samhället, så används idag kontanter fortfarande i stor utsträckning. Handhavandet av kontanter innebär höga kostnader, dels på grund av extraarbetet det innebär för butiker att räkna pengar varje dag, dels för bankpersonal som ska sköta insättningar och uttag och dels för kostnader till vaktbolag som sköter penningtransporter. Om man vet varför kontanter fortfarande används till så stor utsträckning och till vad, så kan man rikta in sina insatser på var man ska öka betalkortsanvändningen. Avgränsningar: Fokus i denna uppsats är på samtliga svenska konsumenter som har rättighet att få ha betalkort från en bank. Syfte: Syftet med denna uppsats är att undersöka om produktegenskaper såsom pris och kvalité påverkar valet om att betala med kort eller kontant.

Syftet med arbetet var att undersöka hur olika reaktionsbetingelser skulle påverka syrgasdelignifieringen av en sur sulfitmassa. De betingelser som undersöktes var utbyte, slut-pH, viskositet och kappatal. Massan som användes kom från Nordic Paper Seffle och alkalit som användes var magnesiumoxid. Syrgasdelignifiering av massan gjordes  i autoklaver i ett PEG bad där tid, temperatur och alkalisatser varierades.Resultaten visar att alla utbyten låg mellan 90-97% och att även de mest aggressiva betingelserna bara gav en viskositets reduktion på 260 enheter, motsvarande 19% av den totala viskositeten.Slut-pH för syrgasavluten hamnade mellan 6,5-9,4 beroende på alkalimängd och temperatur under delignifieringen. Slut-pH minskade när mängden alkali hölls konstant men temperaturen varierades mellan 110-140°C.Kappatalet för massan kunde effektivt reduceras från ett startvärde på 23,4 till ett slutvärde på under 5 med en temperatur på 140°C, alkalisats på 10 kg/ODT och en tid på två timmar utan större förluster av vare sig viskositet eller utbyte.En ovanligt resultat som upptäcktes under arbetet var att delignifieringen tappade i effektivitet med ökad alkalimängd och detta samband gällde vid alla betingelser.En teori om detta kan vara att jonstyrkan i lösningen gör att fibrerna i massan drar ihop sig och att syrgasen får svårare att reagera med ligninet..

This is a study on the outcome of the Swedish Forest Agency´s mission to provide individual advice to private land owners about precommercial thinning. The study was conducted in Sala municipality and included forest owners that had received private individual advice from a Swedish Forest Agency consultant as well as forest owners that had not received individual advice. One of the central issues was to make comparisons between these two groups. The survey was carried out by telephone interviews combined with a smaller field study. The questions were designed to provide information about to what degree the forest owners had been affected by the advice and if there had been a change in the way in which precommercial thinning was performed. In terms of the amount of precommercial thinning that had been carried out, no statistically significant differences were found between the two groups.

The aim for the project was to develop a risk analyse tool for measuring the fire safety level in Cultural Heritage buildings of Visby, Gotland. In 1995 Visby were taken into the Unesco:s World Heritage List with the explanation ?Visby is an outstanding example of a Northern European walled Hanseatic town which has in a unique way preserved its townscape and its extremely valuable buildings? One of the demands for the tool was that it should be easy to use and result into a ranking level in examined buildings. The user of the tool is recommended to be personnel in the fire department. To develop the tool a Multi Attribute Decision Making (MADM) method was used.

In the Real Estate market there are a large number of commercial properties with offices. As acompany or business you are faced with many decisions when choosing your office space.This bachelor thesis examines the concept of architectural quality with focus on beauty and itsvalue for office tenants. The ambition is to find out if beauty is a decisive factor in theselection of office and if there is a willingness to pay for it.The selected question is studied in a case study of Garnisonen where tenants, a propertyowner and an architect are interviewed, all with connection to the examination object.Garnisonen is well suited as a case study because it is Stockholm's largest office complexwith buildings from three different architectural eras. Tenants in the survey represent allarchitectural styles and have different industry affiliation.As a theoretical framework a literature study is presented where the importance of beauty forthe individual, the built environment and society are treated, and also how the office can beused for branding purposes. The interviewees? views of beauty and their opinions on beauty atwork in Garnisonen are presented in the results.

Swedish family companies are facing a tremendous change in the form of generation changes because of the large part of owners that are about to retire. If all 45 000 to 50 000 family companies ceases to exist, Sweden looses a significant part of business trade.There are numbers of different methods for an older generation of owners to transfer their companies to a younger generation such as inheritance, gift, will, internal stock transfer, division?s etc., where inheritance is the most complex area. That an owner of a company dies without any plan for the future of the company is not preferable because the rules of legal successions occur. The law system regarding inheritance is usually not a good method since the surviving wife, who has the primary right to the inheritance, may not be interested in the company.

This major project in Building Engineering has its focus on inquiring into what methods has been used in the planning process of the residential buildingLjusbojen 1. This project has been conducted in cooperation with Kadesjös Ingenjörsbyrå AB, an engineering contractor firm which also acts as the property developer. Initially several different general methods for planning residential buildings have been presented. After the methods from the process of building Ljusbojen 1 has been analyzed compared to the general methods presented in part 1. This shows what the determining factors are during the planning process; factors such as cost, quality, time management, know-how and environmental issues.

The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..
