This report will describe a project between two students from Karlstad University and Markus Norström from Hovercraft solutions. The project aim was to develop a cabin for the hovercraft 380TD. The project was divided into two sub parts; one concerning the design of the cabin and one concerning the engineering. Throughout this rapport you can follow the engineering part of the project. The project has followed a systematic product development process resulting in optimized results for material selection and engineering solutions.

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

The main purpose of the essay was to evaluate whether investments in index-linked bonds were suitable investments for smaller investors on the international finance market. To determine whether the index-linked bonds are good investments, the variables yield, cost and risk were used to measure the index-linked bonds against investments in stocks and funds. The reason for the interest in this subject is that investments in index-linked bonds have grown furiously the last few years. With the growth of the investments the criticism of index-linked bonds has also grown stronger. The critics? main point is the cost of the product, and they imply that investors can create their own index-linked bond and thereby avoid the bank fees.This study used a quantitative approach, because all the data of yield, cost and risk consist of numbers.

The project in question is a joint effort between students at Karlstad University and Marcus Norström at the company Hovercraft solutions. The project is divided into two parts, one focusing on the purely technical aspects of engineering the product and one focusing on the design aspects of the product development. The project described in this report is the design of the product. The assignment from Hovercraft solutions is regarding design engineering of a cabin for the hovercraft 380TD from the manufacturer Griffon hovercraft. The product lacks a cabin and none is offered from Griffon at the time being. 380TD is a relatively small hovercraft with a length of 6.8 metres and a width of 3.8 metres.The surface available for the cabin is not much different from the body of a car.Because of this, research has been focused primarily on car bodies.The product development process used in the project is following a systematic approach.From a chosen concept, the project was finalized with a CAD-modell as well as a detailed prototype.The weight target of 80 kg was reached and the ergonomic aspects were considered developing the sight field, roof- and entrance height.    .

This masters thesis deals with smoke spread via ventilation systems. One aim of the thesis is to investigate and explain the differences in efforts to prevent smoke spread via ventilation systems in different countries. A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.

The purpose of this thesis is to find means of control that secure cost efficiency regarding the accommodation for the employees on missions abroad of the Swedish Ministry for Foreign Affairs. Today the ministry?s cost for the employees? rented housing is 100 million SEK and there is a need of improvement in the control of these costs. A work method for organizational development will be used in order to reach the findings presented in the thesis. First we study the strengths and weaknesses in today?s control system.

According to the European Union waste hierarchy, waste should first of all be minimized. Reuse and material and energy recycling come next. Lastly the waste should be thrown at the refuse tip. In the inner city of Stockholm waste handling can be done in various types of ways. The solutions vary as a result of the type of architecture of the building and its condition.

Requirements Engineering processen, RE-processen, är den tidiga fasen i ett systemutvecklingsprojekt, där RE-processens syfte är att identifiera, verifiera, validera samt dokumentera en mängd krav som ett nytt eller utvidgat system skall konstrueras efter. RE-processen skall mynna ut i en kravspecifikation där de dokumenterade kraven finns samlade.Detta examensarbete behandlar ämnet systemutveckling och fokuserar på konsultföretags metodanvändande under RE-processen. Att fokus ligger på RE-processen beror på att denna fas är den mest kritiska delen i ett systemutvecklingsprojekt.För att få svar på vilka metoder som konsultföretag använder under RE-processen har en intervjundersökning gjorts.Resultatet av undersökningen visar att konsultföretag använder olika metoder under RE-processen. Sättet att använda dem fungerar på ungefär samma sätt med ett aktivt deltagande från kundernas sida. Systemutvecklingsmetoderna är också uppbyggda på liknande sätt med samma synsätt att arbeta efter..

The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

This report describes a new foundation method and compares it with a traditional founding of concrete. This new method is called the Koljern technique and uses cellular glass which is called Foamglas. The Foamglas is compounded to founding elements by lightweight steel beams. Foamglas is an insulation material with high compressive strength, and is rot, insect, vermin and acid proof. The cellular glass is also fire proof and watertight, which makes it a very good construction material.The report contains a study of a number of cases for which the Koljern technique is compared with a foundation of concrete.

The background of this study is the fact that it nowadays is more common to grow wheat after wheat. Usually we plow every autumn to remove the straw, and we wanted to study the effect of alternative methods to do it. We have done this experiment to answer the question if no tillage is better than conventional plowing. The results of the field experiment indicate that there is a link between plant establishment and the choice of equipment, but also a higher weed pressure in experimental plots with only ground tillage. The equipments which left much straw on the top of the ground the problems with fungi were more severe.

The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.

Syftet med studien är att beskriva hur svenska multinationella företag tillämpar cost plus metoden vid interna transaktioner över landsgränser. Vidare har följande forsningsfrågor formuleras: Hur tillämpar företag cost plus metoden? Vilka faktorer påverkar internprissättningsprocessen? Fallstudien är genomförd på Älvsbyhus som är en av nordens största tillverkare av prefabricerade sektionshus av trä med affärsidén att sälja och tillverka färdigmonterade, källarlösa trähus i 1 eller 1,5 plan till marknadens lägsta pris. Den utbredda handeln mellan företag i olika länder har resulterat i ett ökat antal multinationella koncerner bildats, därmed har ett behov av internpissättning för värdering av interna transaktionerna uppstått. Huvudtanken med internprissättningen är att internpriset ska avspegla marknadspriset för varan eller tjänsten, vilket ofta inte är möjligt då ett marknadspris inte existerar.

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

Due to the well-developed rhetoric and the relative easiness to estimate costs, cost considerations are usually more in-depth than revenue considerations when discussing strategies impact on profitability. To avoid dysfunctional companies and poorly judged strategy decisions it is necessary to develop the rhetoric of revenue considerations.By collecting data from 230 respondents in a quantitative study of two grocery stores in Mora, the study aimed to assess the relationship between choice of generic strategy and self-reported buying behavior, considering differing decision-making processes of customers.The results of the study indicate that a differentiation strategy performs better than a low-cost strategy in terms of buyer frequency, number of goods and cost of purchase. However, due to a poor data collection method, the results are weak, and should therefore be questioned. The study indicates that reliability considerations for behavioral measures should be treated in the same respect as psychological measures, and therefore illuminates the need for new methods and measures to be developed..
