För att unvika onödiga kassationer inom fordonsindustrin satsas det mycket på att få fram ?rätt kvalité? på komponenterna från början. Dagens metod är slumpmässiga förstörande tester där endast ett fåtal komponenter testas och förstörs. Denna metod blir dyr i längden på grund av att produkten förstörs och det går inte att följa upp med ytterligare analyser. Porer och inneslutningar vid gjutningen av cylinderhuvud och är ett vanligt problem i fordonsindutrin och när inte varje komponent kan testas och kvalitetssäkras på ett snabbt och effektivt sätt generar det kostnader i både tid och pengar.Målet med detta examensarbete var att utreda om RAM (Resonant Acoustic Method) kan upptäcka dessa porer och inneslutningar med en storlek mellan 1?5 mm i cylinderhuvud från Scania och även undersöka om RAM kan sättas in direkt i produktionslinorna.Med RAM gjordes fem tester per objekt med tre stycken mikrofonpositioner och tre stycken excitationspunkter och med en upplösning på 1,5 Hz.

The objective of this thesis was to get more knowledge before an alternation of generations. In theses I have chose to make two drawings, one for dairy cows and one for cattle rearing. The drawings are made for a future alternation of generations at my parental home in the province Dalarna. The results are made out of educational visits at different farms and literature investigations. Those dairy farms who I visited had different milking system at each farm and the cattle farm I visited had beef production. The farms are placed in the middle and south of Sweden. At 1998 the Swedish Board of Agriculture decided to change the stall breadth and stall length and the result of this is that many farmers had to rebuild their cattle- and dairy buildings or end farming..

Summary The estate of Johannishus is situated in the south of Sweden and in the province of Blekinge, about 8 kilometres from the city of Ronneby. The main building together with the park represents the province´s only example of a well preserved estate environment from the early 1800th Century, and was declared as a historic monument in 1982 because of its unique role in the province. Johannishus Park has during 300 years developed in close relation to the main building, the landscape and the surrounding infrastructure. Each century and owner has had an influence on the park, which has resulted in an interesting visible cross-section of 300 years of Swedish garden history. Most noticeable today are the traces from late 19th Century, but in its oldest parts the park contains structures from the early 18th Century.

Background: Mergers and acquisitions have evolved from initially almost exclusively having been an American phenomenon, to becoming a common occurrence throughout the world. Companies though, are not defenseless against hostile bids, but must take many factors into account when selecting defense measures. Purpose: This paper aims to enhance the understanding of acquisitions through hostile bids on the companies studied. More specifically, this study aims to create a deeper understanding in how Scania and Skandia have chosen their defense measures, or could have chosen, before and during their hostile bidding processes with specific concern for their strategic credibility. Method: This paper is based on two companies listed on the Stockholm Stock Exchange exposed to hostile takeover attempts in a similar time period.

På grund av ökad produktkomplexitet och digitala arbetssätt har fler företag insett nyttan i att implementera och använda sig av bra system för Produkt Lifecycle Management och Product Data Management för att hantera produkten genom dess livscykel. Funktionen hos PLM-system är framförallt att se till att alla har tillgång till den senast uppdaterade datan. Detta uppnås genom ett centralt ställe att lagra produktdata samt möjlighet att strukturera och hantera datan. Scania använder sig av Spectra och Enovia för att strukturera och lagra dagens konstruktionsdata. På senare år har digital provmontering införts i chassiproduktion som ett komplement till den fysiska provmonteringen.

Detta examensarbete innehåller en kartläggning av Scanias arbete med digital dynamisk geometrisäkring samt ett förslag på hur arbetet kan utvecklas.Kartläggningen skapar en översiktlig bild av hur dagens arbete utförs och beskriver de ingående delmomenten. Observationer av hur arbetet utförs har gjorts och dokumenterats och samtal med berörda personer på Scania har skapat förståelse för behovet av ett bättre och mer utvecklat arbetssätt.Scania vill bli bättre på digital dynamisk geometrisäkring för att kunna minska den idag relativt stora verksamheten med fysisk provning av prototypartiklar och färdiga bilar. Ett förslag till ett nytt arbetssätt har tagits fram och förutsättningar för detta har undersökts på företaget. Förslaget bygger på ett ökat samarbete mellan grupper med olika ansvarsområden kopplade till vilka krav som ställs på lastbilen. Utöver den rent organisatoriska delen innefattar det även mer handgripliga förslag på fortsatt arbete som bland annat behöver ett underlag i form av trovärdiga simuleringsmodeller.En jämförelse mellan resultaten från dagens simulering och fysisk provning har genomförts och resultatet visar att vidare arbete med förbättring av de digitala modellerna krävs innan det nya arbetssättet kan anammas tillfullo..

This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

This essay revolves around the Christianisation of the Danish kingdom during the middle ages. Issues like; the length of the Christianisation process and the influence it had on thevillages? structural appearance in the Danish kingdom. A special case study of the villages Kyrkheddinge and Fjälkinge, Scania, is an essential part of the essay. Through writtenmaterial and excavation reports from the both villages the study enlightens the structural appearance of the village and the hierarchy of the farms in the village.

Japanese encephalitis virus (JEV) is one of the leading causes of acute encephalitis in humans. The virus is spread by mosquitoes, mainly belonging to the Culex species. The main reservoirs are considered to be birds and pigs, with pigs constituting the most important reservoir in regard to human infection. During the last few decades the production of pork has increased significantly in Vietnam. With 90% of pigs being kept in households owning 10 pigs or less, pigs are widely spread across most parts of the country.

The purpose of this paper is to study how the wooded hay meadow of the forest district of northeastern Scania is preserved today, and what local history it has, to thereby achieve a better understanding of the dynamics of the landscape and the complex of problems involved in keeping a historical element of the cultural landscape alive. To accomplish this, literature concerning the subject has been studied, experts have been consulted and an example, the old farm Sporrakulla in Östra Göinge municipality, has been studied. The paper states that the wooded hay meadow constitutes an important part of the history of northeastern Scania, where it provided leaf fodder and hay for the farmers keeping cattle. Today, however, only a few wooded hay meadows remain. One of these is the studied example at Sporrakulla, where juridical protection like Natura 2000 and financial support of maintenance like miljöersättningar make sure that the wooded hay meadow will remain.

In order for companies to be competitive they perform different types of development projects.  Due to globalization a greater focus is added on costs, not least on costs in development projects. Project controllers are involved in development projects in order to review the financial aspects. The authors have examined the role that project controllers hold in respect of two Swedish manufacturers, Volvo CE and Scania CV. The investigation has revolved around three main issues where the authors conducted interviews with controllers that do not work in development projects and project controllers in development projects. The goal of the interviews was to gain a greater understanding of the role of project controllers, how this role will differ from those that do not work in development projects and the difficulties faced by project controllers.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Det blir allt viktigare att som organisation skaffa sig hållbara verktyg i skapandet av ett dagligt lärande i syfte att ständigt förbättra och utveckla verksamheten för att kunna stärka sin konkurrenskraft. På senare år har chefsrollen alltmer kommit att handla om att leda och coacha sina medarbetare till lärande och utveckling. Syftet med denna studie var att, med utgångspunkt i en av Scanias fem ledarskapsprinciper ?Bygg kunnande genom kontinuerligt lärande?, undersöka hur första linjens chefer på Scania stimulerar dagligt lärande på arbetsplatsen. Tio semistrukturerade djupintervjuer genomfördes.

This thesis is about making a support for barcode readers and RFID readers on a computermounted in heavy vehicles. The computer has several applications designed for heavyvehicles such as an order handling application. The goal was to suggest an architecture toimplement a support for the readers. The architecture should be independent of whichmanufacturer who has made the reader hardware that was connected to the computer.At first a theoretically study was made around RFID technology and standards for thetransport and supply sector. Then the architecture was developed and a demo implementationwas made.The conclusion of this thesis is to implement support for barcode readers with a wedgeapplication.

This essay focuses upon the Kivik monument and its conservation difficulties, since its discovery at 1748 until modern time. The Kivik monument is found in southeast of Scania, and dated within the Bronze Age period. The perspective of the conservation on the monument has merely been on the monuments inner cist of stone and the rock carvings on the cist-slabs. When the monument was first archaeological examined at 1931, its sizeable cairn (75 m in diameter) had almost vanished and the cist was sheltered by a casing of concrete and metal roof. Between 1932 and 1933 the monument has undergone a large-scale restoration, and this criticized restoration resulted in a low antiquarian value with the responsible authority.
