Då mängden information bara ökar, så ökar även behovet att ha åtkomst till informationen lättillgängligt. Detta skapar då ett behov för ett gränssnitt som kan söka bland informationen. I detta arbete har det undersökts om en implementation av Vector Space Model ger mera relevanta resultat jämfört mot en enklare implementation som inte baseras på Vector Space Model. Sökningen utförs i en relationsdatabas med ett inverterat index, databasen fylls med data ifrån internetforumet Stack Overflow. Genom att bygga en sökmotor som returnerade två olika resultatlistor för varje sökning så fick tio användare testa och utvärdera resultatens relevans.

Problem discussion: Long-term supplier relationships have become more common. Hence, supplier evaluation is a critical activity for many companies. However, making a relevant supplier evaluation is time consuming. Therefore, it is important to decide which of the suppliers to put an extra effort on. Should all suppliers be evaluated in the same way? Previous, focus has been on purchasing of direct material.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

Syfte: Studera sju portföljer och notera den bästa typen av portfölj med högst avkastning till lägst risk.Metod: Sekundärdata är grunden för uträkning av samtliga portföljers avkastningar, risker och korrelation. Studien är deduktiv med kvantitativa inslag av kända teorier av nobelpristagare i ekonomisk vetenskap. Slutsats: Studien visar att stora bolag i olika branscher är ett vinnande portföljinnehåll för denna studie. Stora bolags aktier har visat högre avkastning till lägre risk jämfört med små bolag under studiens tid då ekonomiska kriser drabbade marknaden. Den mest presterande portföljen var därför storbolagsportföljen.Vidare forskning: Längre tidsperspektiv och nya teorier som Jensens alfa samt Treynorkvot är av intresse för vidare forskning för att styrka vår slutsats..

This paper presents a study of the Swedish public service television broadcaster - Sveriges Televisions (SVT) transfer pricing model. The aim of the thesis is to examine the motives for using transfer pricing from a theoretical perspective and if SVT?s transfer pricing model fulfils these motives. We will also examine any potential managerial problems the existing transfer-pricing model might cause and discuss how these could be solved. We have in our study found that the main motive for using transfer pricing within SVT is to allocate internal resources as efficiently as possible.

The number of ideas at innovative companies usually exceeds the amount of available human ormaterial recourses, this include ideas for development of new products. Since they are not able to doeverything they want to do they have to choose between ideas to develop new products. This includesthe decision on when to start, stop or kill a project as well as the thought process of prioritizing betweenongoing and potential projects.Project Portfolio Management (PPM) is an organizational process, with the purpose of systematicallyorganizing and running the activities that aim to evaluate, select and prioritize ideas and projects fordeveloping new products. PPM include four major goals to be fulfilled; Maximizing Value of thePortfolio, Achieving a Balanced Portfolio, Achieving a Strategic Alignment and Running the RightNumber of Projects.The purpose of the thesis was to develop a more visual and formal PPM process for the early stages inproduct development in one department at St Jude Medical AB, Sweden.The thesis was conducted by following a methodology known as Process Modules. The methodology isan approach for developing a PPM process that fits a specific company.

This paper aim to present a model for evaluating what we choose to call HTML-frameworks, a framework that contains a set of CSS layouts and occasionally JavaScript support, based on the characteristics of the software quality standard ISO/IEC 9126-1. The methods used to produce this model is based on a field study that involved making a web portal with the help of a HTML-framework, some relevant literature and an analysis of the framework based on the characteristics of the ISO/IEC 9126-1 standard. The result was a model based on twelve different characteristics; functionality, web browser compatibility, collaborative skills, user-friendliness, documentation, visuals, graphic layout, performance, activity, professional support, replaceability and license. This model should be viewed upon as a suggestion to what a model for choosing HTML-framework could look like, because we haven?t had the time to test it in a real situation, so further studies are needed, and we believe there could be improvements made in the objectivity of the assessments of the characteristics..

The purpose of this essay is to examine Banverket?s problems with its current financial model as it relates to reporting on operations and maintenance work, and to propose measures to simplify the model..

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

 A villas price depends on several important factors. By statistical data, a mathematical multiple regression model was modeled. The model has important explanatory variables such as living space, renovation year and standard points has been taken into consideration, in order to assess their impact on the final price for private homes.By using a statistical program,Minitab 16, the final model was selected with eight explanatory variables. The regression for this model explains up to 67.3 % of the variation on the final price.The results showed percentage wise that the standard points had the greatest impact on the price, there after renovation year and then living space..

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

Purpose: The purpose of this thesis is to examine the ERK model's relevance, validity and potential need of development to better reflect how it looks today (2013). Method: The study is conducted through three surveys; the first two were face interviews with companies that sponsor Swedish soccer teams and the third study was conducted with a questionnaire to supporters outside a soccer stadium. Results: A model that would better reflect the reality of today (2013) could contain company pride, chairman?s whim, exposure, relationships and associations..

To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

Background: Since the early 60?s, the CAPM or Capital Asset Pricing Model, has been an invaluable tool for assessing an asset's expected return, assuming that the asset is added to an already well-diversified portfolio of assets. CAPM theory assume that the unsystematic risk can be diversified and that the systematic, market-specific, risk is determined by the Beta value, from the Greek ?. An investor who takes big risks expect higher returns.One of the CAPM?s basic assumptions is that disruption in the market is not taken into account.
