1-D Modellering av Piezoelektrisk Injektor

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Att bygga för att synas - city branding i stadsplaneringen :

Spectacular buildings and categorized districts are becoming more common elements in cities. In many cases, they are the result of city branding, which means choosing a city image and dealing with it like a brand to profile and compete against other cities. This essay study what impact on and roll in urban planning the trend might have. The first part relies on literary studies and describes what has been written about city branding. The globalization, the experience economy, urban management, urbanization and the theory of the creative class are pointed out as driving forces of the popularity and the spread of city branding.

Madeleine McCann - hela världens dotter : En studie om svenska medier rapportering kring en brittisk flickas försvinnande

Syftet med denna uppsats är att undersöka den första månadens rapportering kring försvinnandet av Madeleine McCann och på så sätt få en bild av vilka faktorer som skapade ett så stort publikt och medialt intresse för just detta fall. För att kunna svara på detta ställs tre övergripande frågor ? vilka aspekter lyfter medierna fram i rapporteringen, hur bidrar dramaturgisk bearbetning till att forma rapporteringen samt vilken betydelse får huvudaktörer i rapporteringen.Undersökningen görs genom en kvalitativ analys av återkommande teman i rapporteringen. Denna kompletteras med en kvantitativ innehållsanalys för att få fram statistik på hur mycket utrymme visa aspekter får samt vilka benämningar som görs vid porträtteringen av Madeleine McCann.Det undersökta materialet består av artiklar från tidsperioden 5 maj 2007 till och med den 7 juni 2007 i Aftonbladet, Expressen och Dagens Nyheter.De teoretiska ramverk uppsatsen utgår ifrån är teorier om socialkonstruktivism, nyhetsvärde, medielogik och narrativ berättande.Resultatet visade att den främsta faktorn till att fallet uppmärksammades är genom den personifiering som gjordes av Madeleine McCann och hennes föräldrar. Personifieringen leder till att rapporteringen kan konstrueras till en nyhetsberättelse.

Denim is not dead

För att ett företag ska kunna hålla sig flytande på marknaden idag krävs de att de har hundra procent koll på vad som sker i deras fabriker och att de strävar efter en mer hållbar tillverkningsprocess. Att försäkra konsumenterna om att fabrikerna inte använder sig av barnarbete eller dåliga arbetsförhållanden räcker inte längre utan det krävs en bredare kunskap inom miljö och hållbar utveckling för att den trogna kunden ska stanna. Syftet med denna rapport är att kontrollera det nyuppstartade företaget DENIM IS DEAD?s produktion och utvärdera om hur man kan förädla de olika processtegen samt skapa transparens gentemot kund.Metoden som arbetet utformades efter var genom en fallstudie som är baserad på en mestadels deduktiv metod men med inslag av induktiv metod. Där grunden lades genom en utförlig faktainsamling för att i rapportens senare del kunna analysera de hypoteser och problemformuleringar som ställts.Målet med rapporten var att ta fram en metod eller produkt som ska underlätta kommunikationen med DENIM IS DEAD?s kund.

Skogsskötsel för att minimera stormfällning över järnväg :

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

Allanblackia stuhlmannii ? a tree under current domestication: what are the soil requirements?

Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.

Sensory profiling of Swedish white wines and a contextual analysis of Swedish viticulture

The aim of the study is twofold, to generate a sensory profile of Swedish wine today and to investigate the opinion of both wine producers and wine experts on viticulture in Sweden and wine from grapes grown in Sweden, achieved through a contextual analysis comprising a literature study and interviews with wine producers in Sweden and Denmark and wine experts from Sweden and Germany, and a sensory analysis at the company Ipsos. ?Mixed methods? was the chosen research strategy as the semi-structured interviews gave qualitative results and the sensory analysis would give quantitative results displayed as spider charts. There is a lack of studies investigating how the Swedish wine is perceived by consumers and consumers might be unaware that the Swedish wine, established through ?trial and error?, is increasing in quality every season, creating a need to display the sensory profile of Swedish wine to strengthening the perception of Swedish white wine. This study shows that the Swedish white wine today is a wine with a fresh, citrusy and flowery aroma and a fresh, citrusy and green apple taste, however, a sensory analysis cannot show if the attributes are those that are desired by the customer, a consumer test is necessary to conclude that. Trends point towards locally produced products, one reason why Swedish wine has great potential, yet the future needs to be secured through job opportunities and education. Creating an approval system for Swedish wine is suggested as a future improvement, it is a common procedure in most wine regions.

Claw and leg lesions in preweaning piglets : a comparative study of piglets reared on structured polyurethane coating and piglets reared on concrete floors

Floor surface in pig facilities can have an impact on animal welfare and pig health, as it can cause the pig physical damage and thereby increased risk of infectious diseases and lameness. The development of pig housing systems has resulted in a decreased use of bedding. It seems hard to find the optimal floor in farrowing pens, as it must suit both the sow and piglets. The floor friction needs to be adequate to avoid slips and at the same time should the floor be non-abrasive. Abrasions and lesions caused by the floor are not only causing the animal suffering, but are also negative from an economical aspect.
