Hawk Turbine AB tillverkar mindre jetmotorer som ofta används i små obemannade och radiostyrda flygplan. I flygplansmodellen Lockheed T-33 Shooting Star är motorn monterad inuti planet varför luften måste ledas ut till atmosfären. För bästa möjliga prestanda måste ejektorn och utblåsröret som leder luften dimensioneras efter motor och flyghastighet.En 3-dimensionell CAD modell av flygplanets installation skapades och därefter simulerats i en virtuell vindtunnel med hjälp av datorprogrammet SolidWorks Flow Simulation. Flera olika utblåsrör i varierande storlekar samt olika former har testats för att avgöra om ändringar kan förbättra prestandan ytterligare.Simulationsresultat visar att det går att förbättra nuvarande konfiguration med 5,99 % om diametern på utblåsröret minskas från 75 mm till 70 mm med en bibehållen form på utblåsröret..

Event is a phenomenon that lately has become more common, especially within the tourism industry. This essay is a study within human geography and with focus on the meaning and the design of events. The purpose with this essay is to examine and describe the concept of event and to show how events can influence a region. Falkenberg is situated in the county of Halland by the west coast and the sea and because of that a natural tourist destination. The city is a known seaside resort since the end of the nineteenth century.

This paper investigates the determinants of corporate cash holdings for a broad sample of Swedish non-financial firms in the 1999 - 2009 period. Using a fixed effect regression model, we find that firms with riskier cash flow hold relatively high ratios of cash to total assets. This is in line with both the precautionary motive and agency motive for cash holdings. Net working capital is found to be negatively related to corporate cash holdings. A result commonly interpreted as support for a negative substitution effect between net working capital and cash.

 The purpose of this essay is to analyze and understand which difficulties that e-company's struggles with the most, and what their strategies are to overcome this problem. Sales of clothing through e-commerce have made the shopping experience faster and more comfortable, but on the other hand it has created a couple of problems which makes a big difference in the purchase of clothing, we are partly talking about the absence of the testing opportunity. To not know whether or not the shirt or pants will fit, leads customers to a game of gamble every single time they purchase a garment. Another problem which makes customers nervous before a purchase is the absence of a physical salesperson. This might lead customers to question whether or not the company exists.

The aim of this thesis is to clarify the affect that preferential and regional trade agreements have on the World Trade Organization (WTO), as being establisher of the international trading regime. The essay is an explanatory literature study, which strives to answer the following questions:Are regional and preferential trade agreements a threat or a complement to the WTO?Is an undermining of the MFN principle weakening the WTO?How do regional trade agreements made by the EU affect the future of the WTO?The empirical material is to be analyzed using an explanatory framework, which is based on neo-liberal instutionalism, theories on regime changes and a game theoretical approach, using prisoner?s dilemma. I will employ the EU-ACP relation, the Cotonou agreement to exemplify how an agreement of this kind can have an influence on multilateral trade. The result shows that preferential agreements do have an impact on the WTO, one that is fairly negative in scope.

När en kassaflödesvärdering genomförs prognostiseras företagets värde genom att summera framtida kassaflöden och diskontera dem med företagets kapitalkostnad. På grund av att prognostiserade kassaflöden är uppskattningar inför framtiden karaktäriseras en värdering alltid av hög osäkerhet. Till underlag för prognoserna används en omfattande mängd information. För att ett tillförlitligt värde ska kunna beräknas är det viktigt att relevant och pålitlig information samlas in och hanteras på ett effektivt sätt. I dagsläget är det problematiskt att hantera omfattande mängder information och ett tillräckligt datorstöd saknas.

This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..

Detta är ett uppsats på D-nivå. I en tidigare kurs, inom vårat program Data- och Systemvetenskap, kom vi på en idé om hur man kan förbättra/komplettera utbildningen av nyanställda som befinner sig i en stressig arbetsplats på företag där det är ett ständigt behov av återanställning av personal. Vi utvecklade detta koncept och kom med idén till en simulator som kan utbilda personal samt minska stress hos nyanställda. Idén mognade till en Serious Game simulator baserad på en Wii-kontrollerad PC-baserad simulator med Bluetooth-stöd.Syftet med denna uppsats är att skapa en guide om grunderna i en simulator som utnyttjar Wii-kontroller som externa inmatningsenheter. I denna guide kommer vi att täcka hur Nintendos Wii-kontroll fungerar, hur man kan skapa enkla 3D-modeller i Blender och även hur detta kan implementeras i Microsoft XNA.

The aim of this report is to increase the knowledge and understanding of the problems within the production at AQ Enclosure systems, and thereby achieve a more stable flow throughout the whole process, a better working environment and better competition advantages. The internal flow along with the external cooperation is very important for the company, because it views flexibility and short leadtime as it is the most important competitive means. The part of AQ production that?s been investigated is the manufacturing of ATM-machines, where the costumer is Banqit. This company is a rater small company with about 4 % of the world market of ATM-machines.In order to achieve the aim of the report extensive interviews have been carried out with employees at AQ.

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

In health care today at Uppsala County Council the daily work involves spending time at the computer. IT-systems were implemented to support and aid the care givers in their work. Around these systems there is a support organization to support the users in using the system. The aim of this thesis is to investigate this organization in terms of how well it works and how successful it is in helping the users. This has been done by investigating the flow of information trough the organization and by focusing at the role of IT-coordinators with responsibility for support, process development, education and statistics.

The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn.

During the Swedish banking crisis in the early 1990?s, the government paid out 65 billion Swedish kronor to save Swedish banks from bankruptcy. In the process, two banks left the private sector to be taken over by the state. This thesis builds on a study from 1998 in seeking to quantify the financial end result for the Swedish government from the subsidies. Taking a cash flow approach and accounting for the time difference, it starts with the money paid out during the years of crisis and subtracts the money that has since been returned to the government by successful management of the relinquished assets.

The main focus for this essay is to describe the relationship between human and nature through a material investigation that takes its shape through sculpture. With the help of a fairytale-like story the reader can share the creation of the sculpture and how my thoughts flow through the process that will result in an exam project. Rooted in earlier projects I discuss the crash between civilization and the wilderness as well as talking about the likeness of the creative process and child play. I also discuss the body's place in the forest and the loneliness that we humans created that has cut us off from the rest of the creatures and plants in the forest. My aim is that in the final piece I will create a fiction place where these can be joined together again.

I detta arbete redog?r f?rfattaren f?r en del av spelmusikens historia, vilka influenser och tekniska begr?nsningar som lett till att bit-musik, med fokus p? 8-bitars musik och med inslag av 16-bitars musik, l?ter som den g?r, samt g?r en analys av 8-bitars musik p? bakgrund av musikteori, musikpsykologi och kompositionsmetod. F?rfattaren diskuterar ?ven begr?nsningar utifr?n ett historiskt perspektiv, och redog?r f?r uppkomsten av kompositionsmetoder som anv?nts genom ?rhundradena, fr?n Bach till 1980-talets 8-bitars komposit?rer. F?rfattaren kommer fram till att det g?r att applicera samma kompositionsmetoder i 1980-talets spelmusikkontext som under exempelvis barocken, och att analysera klassisk musikteori ?r anv?ndbart f?r att f?rst? och skriva 8-bitars musik.
