Ett spels karta är begränsande i det att när man valt en viss storlek kan man inte gå utanför den ramen utan att göra relativt resurskrävande operationer. Denna undersökning genomfördes för att se om en trädstruktur kan användas som lösning att hantera en honeycomb-struktur på ett lämpligt sätt för att ständigt kunna utöka ett spels karta. Resultatet visar att det är möjligt att använda trädstrukturen relativt bra till växande kartor men att det inte är att rekommendera till spel, eftersom strukturen i sig är en omväg. I samband med denna karta skapades en slumpmässig path-generator som skulle kunna användas till att generellt skapa slumpmässiga kartor i spel. För att se vad försvårigheter man stöter på när man utvecklar en slumpad map-generator, vilket visade sig vara svårt i och med att man hittade många specialfall..

The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.

During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..

The Promised land ? A letter analysis of America letters from 1850-1870 This essay is about the Swedish emigration to America. This essay will focus on the period 1840-1870, where the main focus will be the american civil war, and what the immigrants wrote back to their relatives in Sweden. This study will also focus on the integration of Swedish immigrants.My main question are what did the swedes write back to Sweden during the war? And how did it differ from the period before and after the war?But also can a war assimilate a immigrant faster than it would be done without the war?The conclusion that has been made is that the war did help the swedish immigrants to integrate much faster than usually.

Art.39 är grindvakten som inleder kapitel VII i FN-stadgan och tröskeln vid vilken säkerhetsrådet går från att vara ett multilateralt organ till ett globalt verkställande organ. Konceptet ?threat to the peace? är det bredaste, otydligaste och viktigaste begreppet i art.39 FN-stadgan. Genom att framställa de centrala förutsättningarna för tillämpningen av art. 40-42, öppnar art.

Between 1814 and 1905 Sweden was in a union with Norway. During this time the two countries collaborated in many ways but there were also several differences between them. Swedish people went to Norway, often to find work, and this essay aims to examine who they were. An archive in Värmland, which people returning to Sweden during the years 1894 to 1903 were registered in, gives information about these people. From this we learn that they were mostly men in the ages 15 to 44 and they came from all over the country.

Ombord på fartyg är det inte önskvärt att få strömavbrott, en så kallad blackout.Examensarbetet har undersökt i vilken utsträckning det är möjligt att utföra jämförande ochförebyggande studier med haverirapporter från europeiska flaggstater som underlag. Detta föratt undersöka återkommande brister, på fartyg eller i arbetet ombord som har orsakatblackout. Dessutom har även möjligheterna till att kunna kategorisera fallen undersökts.Kategorierna var tekniskt fel, operativt fel och organisationsfel. I ungefär häften av fallen gickdet inte att kategorisera en blackout till ett fel, eftersom det annars var en kombination av fel.Däremot finns återkommande fel där händelseförloppen är väldigt lika. Till exempel var hetaytor inte korrekt isolerade, vilket resulterade i brand vid bränsleläckage.Undersökningen visar att det finns en bristfällig symmetri i rapporteringen av haveri medavseende på språk, struktur, omfattning och publiceringsform.

The present study concerns a concept development of a product idea that Bengt Magnuson, associate professor, had when a heavy storm caused a widespread power failure of long duration. With a basic power-producing unit one should be able to get through a power loss. The product could also be useful for other tasks if different modules are connected, e g grass mower or snow-blower.According to the product idea the basic unit will be able to produce electric power enough for a fridge, freezer, TV, and a few electric lamps. Normally the basic unit can be used e g as a mower, when such a module is attached. An increased number of tasks would make the contraption useful and tempting for those who do not own an electrical power set in reserve.

Skolfartyget M/S Calmare Nyckel, som ägs och opereras av Sjöfartshögskolan i Kalmar används i utbildningssyfte av både blivande nautiker och maskinbefäl. Driften av NOHAB-dieseln, som används som generator, har varit problemfylld med ständiga och oförklarliga stopp. Det larmsystem som installerades av Oskarshamnsvarvet var högst bristfälligt. Larmsystemet var personfarligt då det var byggd på 230volt, dessutom var larmpunkterna byggda i serie med endast en stoppindikering. Avsaknaden av elritningar över systemet gjorde att bristerna i larmsystemet inte kunde felsökas. Dessutom fanns ingen indikering i kontrollrummet utan endast lokalt vid NOHAB-dieseln. Vi har gjort en nyinstallation av larmsystemet på mer personsäkra 24VDC, med samtliga larmpunkter parallella och med tillhörande indikering på panel, både lokalt vid NOHAB-dieseln samt i pulpeten för god översyn av systemet.

HAFA Bathroom Group has given us the assignment to develop a standardized back panel for their bathroom cabinets. This cabinet is going to be applied to most of their current and future cabinet solutions. To this point, they have constructed unique suspensions-and back panels for most of their cabinet models. They have also been forced to pull wiring and assemble the cabinets differently because of factors like; position of the wall sockets, dimensions of the cabinets and their shapes.The company wants to distance themselves from their current solution, firstly because the cost of having manpower to design each individual suspension solution, secondly because they will save a lot of money when the manufacturing process requires a minimum of components to be constructed. As a result of this, the company can use their resources better to develop future products.The main idea is that the consumer isn?t required to change the suspension or back panel when they decide to buy a new cabinet.

AbstractThis study examines the technologies appropriate in developing back-and solutions for search-driven user interfaces of e-commerce sites. The study is based on existing research in search-driven user interfaces of e-commerce sites from a design point of view, but instead the focus of this study lies within a back-end perspective. This choice of focus is a result of the gap that was encountered within research and other literature when it comes to general advice in how e-commerce sites best should build back-end solutions to support search driven user interfaces. The technologies that have been examined and compared are traditional relational databse management systems (RDMS) and the newer so called No-SQL database management systems, and also traditional search engines and the newer variant s of search engines. The study concludes that in some cases it is appropriate to combine traditional and newer technologies when it comes to databases, while the comparison of search engines indicates that there are some newer search en gines that have the ability to meet more of the needs that can be identified on the back-end solutions.Primary data consists of interviews made ?face to face? with experts on the subject and questionnaires addressed to selected e-commerce companies via e-mail.

Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.

The main focus of this study is to explore Swedish soldiers? experiences of the transition back to everyday life after international service missions. This includes the help and support that they have received and also what barriers to care they have experienced during the transition back to everyday life. The theoretical perspectives of this study are social identity and stigma theory. This study was performed using a qualitative method and includes six individual interviews with active duty officers within the Swedish armed forces.

Som ett sista arbete på högskoleingenjörsutbildningen i maskinteknik på Umeå universitet så har jag sett över servicevänligheten på ett reservkraftsaggregat. Attacus Power AB har stått som värd för detta arbete och även tillhandahållit arbetsplats under utförandet.Ett reservkraftsaggregat är ofta en dieseldriven motor kopplad till en generator som alstrar ström. Denna ström kan sedan användas för att driva sjukhus eller liknande vid ett eventuellt strömavbrott.Modellen som skulle ses över heter GTC-200MSS och den är en extra tyst modell avsedd för platser som filminspelningar och liknande där ljudnivån är en viktig faktor.Det jag skulle utföra var att försöka hitta en lösning där motor och generator, med så litet ingrepp som möjligt, kunde tas ut för underhåll.Arbetet började med att olika lösningsförslag togs fram. Allt från att vicka av hela höljet, till en ny utformning av modellen. Efter att alla förslag presenterats och gåtts igenom med inblandade på företaget, så beslutades att en lösning där en truck eller liknande med hjälp av sina gafflar kunna lyfta ut motor och generator var den bästa lösningen.För att göra det enkelt för de som skulle utföra ingreppet så gjordes en enkel manual.En modell togs fram där truckens gafflar legat till grund för utförandet samt dess belastningsfall.

Corporate Social Responsibility (CSR) is about facing responsibilities towards a company?s employees, customers, stakeholders, suppliers and the environment. As customers and consumers came to seek companies that were dealing with CSR a rapid wave of ?forced? implementations of social responsibility began. Fair Travel Tanzania, which has CSR as the foundation of the company, says that they are transparent about what they do and how they give back to the locals, could it be a problem with this? And how do they actually give back to the locals? Is it possible to measure the impact of CSR activities within the company? And if so, how?.
