This essay is an enquiry about how companies as participated in a Lean pro¬duction education use this education. The essay describes also how one works with the implementation of Lean production and how they believe that they will work. The enquiry tries to create an advisory material for other companies that are in the beginning of implementing their own Lean production systems. There these companies? gets a picture of how other companies have done during their try to create a functioning Lean production system.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

The purpose of this thesis is to examine how e-commerce companies work with their relationships to customers. We have conducted a case study of two companies, Koll and Webbshoppen, both active in the e-commerce industry. Our empirical study has shown that it is important for e-commerce companies to create long-term relationships to their customers, but it can be difficult to create these relationships since the companies have little contact to the users of Internet. To build relationships, e-commerce companies market themselves through different types of media to create awareness. It is also essential to be situated high in search engines.

The advantage and the possibility of keeping track of a number of vehicles to make work practice more effective and smooth is today a favorable choice for Visual Units Logistics customers. We?ve been evaluating the software and trying to take it one step further and letting not only the individual user, but maybe, the company as a whole benefit from its advantages. This has been done by using methods like letting ourselves get to know the software, user case studies, workplace studies, interviews and future workshops. This resulted in a prototype introducing a new function designed with all collected data in mind trying to make the software, Visual Units Logistics, even more effective for the every day work practice of the user.

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

Traditionell systemutveckling präglas ofta av långa utvecklingsprocesser och en oförmåga attmöta förändrade behov från kunden. Problematik med buggar i mjukvaran och förskjutnadeadlines uppstår kontinuerligt och leder till högre kostnader för företag.För att komma till rätta med dessa problem behövs en systemutvecklingsprocess som belyserproblem direkt när de uppstår och därmed tvingar de inblandade till reflektion över processensom skapar problemen vilket belyser de verkliga bakomliggande orsakerna. Låg kvalitet påmjukvara är ofta ett symptom på djupare organisatoriska problemEtt synsätt som syftar till att möta dessa problem är lean software development. Synsättet harinspirerats av lean production som är en beskrivning av The Toyota Production system vilketi sin tur är det arbetssätt som har tillämpats av Toyota under flera decennier i den traditionellatillverkningen.Mary och Tom Poppendieck har beskrivit sju principer och 22 tankeverktyg som kananvändas för att skapa en metod för lean software development. Studien visar vilka styrkoroch problem som lean software development och lean production beskriver generellt samtvilka styrkor och problem som finns avseende beskrivning av Poppendieck's principer ochtankeverktyg i synnerhet.

The global spread of the Internet has enabled busniesses and consumers in all industries to be better informed. Consequently, the buying process has appeared to become different from what tratditional models implies. As the buying behaviour among customers is evolving, selling companies are responding to this change. This thesis evolves around the consequences that the developing relationship between buyer and seller in business-to-business companies has led to. The topic in focus is the buzzword and phenomena "content marketing" with its marketing and selling strategy.

There are several ways of conducting software testing where some may include users and others may include personnel whose work task is to execute test on systems. Although most developers and project managers understand the point of testing the system, it is not always being done and the most common reason is that there is no time for it. However, this is a false assumption as it may instead cause some bugs in the system that would not have been there in the first place if tests had been there to prevent bugs in the code.My purpose for this thesis was to find suggestions for changes in the development process in an ongoing project used by Acino and Svenska Försäkringsfabriken in order to increase the quality of the system used. In this thesis, I have approached the purpose by pursuing a case study of the two companies through observation and interviews. By doing this I acquired the relevant information to make suggestions for change.

The purpose of this paper is to examine and analyze past development of mutual funds in large and small mutual fund companies and see if there are any differences between these two segments. Limitations on the number of funds have been made by choosing Nordic mutual fund companies that invest in emerging markets over an 11-year period. The study is made on 66 mutual funds managed by 13 mutual fund companies in which the segment of small fund companies includes seven fund companies with assets under management less than 100 billion SEK and the segment of large mutual fund companies includes six fund companies with assets under management more than 400 billion SEK. In the comparison of the segments the Sharpe ratio has been used to calculate the risk-adjusted return. The study shows small differences of the risk-adjusted return between the segments.

This report describes a final thesis done during the spring of 2008 as part of the bachelor degree in computer engineering degree at the School of Engineering in Jönköping.The client is working in the consulting business and is involved in, amongst others, work regarding information security. Within this field they perform so called Threat, Risk and Vulnerability assessments. Today these assessments are done by a predefined method, but many details are controlled by the person documenting the project. A wish was made that the implementation was standardized, it should also ease the task of estimating the need for time and money. The solution for this seems to be a software tool.

Since companies have realised the importance of customer loyalty and since the service sector has gained higher significance in recent years, we found it interesting to study what leads to customer loyalty in service companies. The theories we have chosen to consider are customer loyalty, service quality, service guarantees, affinity marketing, loyalty programmes and customer clubs, the customer in focus and other factors that influences customer loyalty. To find out how service companies are working with cus- tomer loyalty, we have conducted a case study within three service companies. Our findings are that customer loyalty has a significant importance for the companies we studied. Quality and personnel were the factors we found had the greatest impact in service companies concerning customer loyalty.

AbstractThe ability to read and write is a very important skill in today?s information based society. Most of us learn how to read and write, but not everyone is blessed to do this without struggle. Dyslexia is a very common learning disability and therefore I found it interesting to study how teachers teach students with dyslexia.By studying the literature and by interviewing teachers, I found that dyslexia is a very complex disability. The teachers have to adapt their way of teaching in a way that a student with dyslexia can participate.
