When performing a QRA you have to consider a number of accident scenarios. How many scenarios you choose often determines the time and resources needed to perform the QRA. The report investigates the possibility that a QRA can be performed using only a few representative scenarios. Further it presents a discussion on how these scenarios should be constructed..

In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.

As a newly graduated student in construction you rarely have as much knowledge as you wish you had. It is a complicated line of business that requires knowledge and understanding of both technical solutions and interaction between actors. It is impossible to be fully learned and with that much unknown it can be hard to know where to start. This report is one step in the right direction. It contains a planning that contains construction and installations for a one level house in Kiruna with its different choices motivated.

The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the visionsystem.

This work deals with mathematics teaching in preschool classes. The purpose of my study is to investigate the preschool classes? teachers' aspirations for the children learning mathematics in two different preschools. To achieve my goal, I formulated the following questions to be explored and answered through interviews with five teachers.  Does mathematics in preschool classes have a prominent role in educators' planning? What perception do the educators in the field have about the learning and teaching of mathematics in the preschool classes? How do the teachers understand their own work with mathematics in preschool classes in relation to multilingual students?                                A qualitative interview method was applied.

 BakgrundI november 2010 avskaffades revisionsplikten för små aktiebolag i Sverige. Anledningen till lagändringen var att regeringen ville sänka kostnaderna för små bolag, samt att regeringen ville att Sveriges lagstiftning skulle harmoniseras med EU:s lagstiftning. Regeringen menade att bolagen efter revisionspliktens avskaffande skulle använda den insparade kostnaden till att köpa andra tjänster från revisionsbyråerna.SyfteSyftet är att beskriva hur den avskaffade revisionsplikten för små företag har förändrat kundunderlaget och tjänsteutvecklingen för några utvalda revisionsbyråer. Vidare är syftet att beskriva vilken betydelse revisionsbyråerna anser att revisionen har för de små företagen.MetodI uppsatsen har en kvalitativ metod använts. Intervjuer med 6 olika revisionsbyråer i Sundsvall har genomförts.

Den här rapporten redogör för utveckling, design och sömnadskonstruktion för en sadelpadd. Rapportens ämne valdes för att jag fann det intressant och har själv stort intresse för hästar och produktutveckling. Fokus på rapporten låg på att ta fram en fungerade prototyp som testades av hästägare för att se om en distansväv skulle klara av att vara det stötdämpande och tryckutjämnande materialet i en sadelpadd. Rapporten och utvecklingen av rapporten bygger på en enkätundersökning och några intervjuer med relevanta personer insatta i ämnena sadelpadd och ryggskador hos hästar. Utifrån den insamlade informationen från de intervjuade och de som svarade på enkäten samt tidgare skrivna källor gjordes en studie i hästars uppkomst av ryggbesvär.

In this report the balconies? abutments for a property in Bo01-area in Malmö has been studied. The property which is called Vitruvius contains four build-ings where two of them have corbelling balconies with intermittent abutments. With intermittent abutment means that the 50 mm thermal bridge insulation that the balconies is equipped with, is broken regularly by a 300 mm concrete heel. The reinforcement bar that holds the balcony runs through this heel.

Yahtzee is a game based on luck. Yet there are algorithms designed to give an optimal result and succeeds in doing so. This report compares the end result of an optimal algorithm to an algorithm that has been modified for the multiplayer scenario. The modified algorithm tries to win over the optimal algorithm through taking greater risks in its decisions when falling behind in points. The results show that it is not favorable to do so.

Background: The purpose of this study was to explore the reasons that motivate women to seek cosmetic breast augmentation surgery, to examine their self-concept and how they relate to their breasts.Methods: Ten female postoperative participants who have undergone an aesthetic breast augmentation surgery on private clinics were interviewed using an unstructured interview format. Self-report questionnaire was used as a complement to the interview. The purpose of this was to examine women's self-concept. Six female postoperative participants who have undergone a breast augmentation surgery on public clinic and had medically confirmed defect also completed the measures.Results: The results of the interview analysis showed that some participants experienced positive physical and psychological outcomes of surgery and some did not. Several main themes were identified relating to the initial reasons for performing surgery.

To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.
