A shock absorber is used in road vehicles to provide comfortable driving and to optimize the grip. The characteristics are advanced and it takes powerful tools to model a shock absorber. Öhlins Racing AB in Upplands-Väsby is looking for a tool to physically describe their products; in this thesis the task is performed by using the modeling language Modelica and the simulation tool Dymola. The mode
This thesis handles the problem with fluid selection in organic Rankine cycles application. The main goal was to write a program that based on user defined variables finds the maximum power output from a range of fluids. The program was programmed in Matlab and is coupled with REFPROP that return the fluids characteristics as enthalpy and entropy etc. The program is preloaded with the fluids foun
This study investigates the concept of ‘trust’ through exploring the relationship between answers to a standard survey questions and behaviour observed in an economical experiment. The survey question has been used in a wide range of reports and studies related to economic development. Therefore, ensuring that the survey question has high validity and that it accurately captures the level of trust
Summary This thesis is a study which primary objective is to examine the court´s risk assessment in legal custody, and contact disputes when a child is at risk of being harmed. My thesis also includes an interdisciplinary perspective to give a more detailed understanding of the process – of which consequences it entails if authorities and courts don´t make reliable risk assessments. Physical, psyc
In recent years, self-employment has emerged as an important avenue of economic livelihoods for immigrants in the western world, including the Chinese immigrants. The debate on immigrant self-employment has been widely discussed across academia and given a considerable attention by researchers, policymakers and governments. This study addresses the self-employment experience of Chinese immigrants
Purpose: The purpose of this thesis is to implement the One Supplier Capacity Process, a standardized method of working with capacities within IKEA. In order to do this the current way of working with capacities is investigated prior to the actual implementation of the process. The key contribution of the authors is the development of a template to support the implementation process and ensure acc
This master thesis is about the mathematical modeling of an inventory control system. The system is a single-echelon two-location system with one type of item. The locations replenish from a supplier that is assumed to have an ample stock. The demand is modeled as customers arriving according to a Poisson process with a known intensity and each customer only demands one item. In addition to replen
Background Lantmännen is one of Scandinavia’s largest and problem corporations in agriculture, food and energy. Since many of the corporations’ markets are mature and highly competitive there are low margins and hence a constant need for new and improved products, processes and services to maintain profitability. There is also a constant increase in complexity and cost of research and development,
Issue of study For the past ten years there has been a remarkable growth in the wind power industry. During 2003 - 2010 the production capacity increased by 456 % in Sweden, corresponding to total capacity of 2019 MW. An additional 754 MW was installed in 2011, and there is a planned capacity installation of 950 MW for 2012. This will, according to a prognosis from Svensk Vindenergi, generate a po
In July of 2009 punitive measures were taken by the Swedish government in order to deal with the somewhat new phenomenon known as grooming. The law, called “contact with children for sexual purposes” requires that the adult perpetrator contacts a child, with the purpose of committing sexual offences at a future meeting with the child. Although the law was received with gratitude from many parts of
Background and the Situation at Company X To remain competitive, it is essential for companies to take advantage of new business opportunities. However, seizing new opportunities often imply changes within the organization, and projects associated with change are bound to encounter resistance. To efficiently manage change and thereby avoid resistance and engage in measures that generate support fo
Gamification is a new trend that seeks to engage people and change their behaviour by implementing game-design thinking in non-game contexts. Recent analytics predicts that more than 70 % of the world’s 2000 largest organisations will have at least one gamified platform by 2014, which indicates that gamification is, and will continue to be, very important in the future of IT-strategy and digital m
To guarantee that the products in the IKEA catalogue are available when requested, IKEA needs to plan and secure capacity. IKEA has developed a process called ONE Supplier Capacity Process to solve supplier capacity issues in a more proactive way. The thesis is focused on suppliers’ in the category Frames and Mirrors with frames in Greater China. Purpose The purposes of the thesis are fourfold: •
Company X Equipment division is a mature organization that has experienced a desire to broaden the knowledge about the market potentials of the Canadian markets. There is also an ambition within the organization to improve the sales in Canada by exploring previously unknown market opportunities. The needs for increased knowledge are experienced both at the Canadian sales office and at the Lund hea
Nyexaminerade anestesisjuksköterskor kan ha svårigheter att klara av olika situationer. En ny studentsalsmodell skapades för handledning av anestesisjuksköterskestudenters kliniska träning i pargrupper vid tre tillfällen. Syftet med studien var att undersöka och beskriva en ny modell för pedagogisk handledning operationssal erfors av studenterna. Tolv studenter som genomgick sin verksamhetsförlagd
Det finns olika uppfattningar om huruvida påförande av skattetillägg vid tillämpning av skatteflyktslagen harmonierar med skattelagstiftningens syfte. Det har framförts att det finns ett bristande logiskt samband mellan skatteflyktslagen och skattetilläggsbestämmelserna. Det har vidare hävdats att domskälen många gånger endast är svagt förbundna med lagtext och förarbeten, det har även ifrågasattsIn cases of incorrect information in the declaration of income the Swedish Tax Agency (SKV) can decide on tax surcharge. Decisions according to the Tax Evasion Act (1995:575) are, however, only decided on by court. It has been argued that there is a lack of logical association between the Tax Evasion Act and the decision on tax surcharge and that the applicability of the Tax Evasion Act and the ta
To date China has become one of the largest receivers of foreign direct investment (FDI) and this FDI has had an important role in China’s economic growth. It is therefore important to study the determinants of FDI in China. This paper evaluates if general applied tariffs on Chinese imports in China’s trading partners influence the amount of FDI to China. In previous studies this approach has not
When capturing digital video there is always some amount of noise in the resulting signal. This is more pronounced in low-light conditions. In this thesis we have evaluated five algorithms for motion detection and noise reduction. All algorithms produce a filtered image and a motion mask. One of the algorithms is based on block-matching, one on fuzzy logic and one on low-rank matrix completion. Th
This study aims to illuminate the perception of Spanish and English language bloggers and to understand them and their activities from the analytical perspective of an online European Public Sphere (EPS). The research, using a methodology of semi structured online interviews, answers two questions. The first one is how these bloggers give evidence of an actor-based online European transnational bl
