The aim of this small thesis is to investigate if the probability of business failure is higher at the time of divestment than at the time of acquisition for portfolio companies that have been subject to private equity ownership. The background for this thesis is the widespread critique aimed at private equity firms, claiming that they increase the risk in their portfolio companies. We have performed a study of 53 buyout transactions, involving Swedish manufacturing companies, covering a time span of 13 years, from 1995 to 2007. We find evidence of an increased risk of business failure for the portfolio companies with a short forecasting horizon (within one year). The absolute increase in the sample is however small.

The work describes the development of an adjustment algorithm that will replace today?s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system.Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two.The report describe the development of the algorithms and how they behave during simulations and tests on real robots.

The portfolio shows higher returns than the OMX index..

En portfolio tas vanligen fram för att visa på vilka kunskaper man förfogar över. I vissa fall handlar det om att visa upp grafiska verk, i andra fall handlar det om att visa tekniska kunskaper. Ibland handlar det dock istället om att slå ihop dessa båda. Det är främst i möjligheten att kombinera presentationen med tekniska och grafiska kunskaper en webbportfolio skiljer sig från en traditionell portfolio. Målet med det här examensarbetet inom IT, medier och design har varit att ta fram en webbportfolio som är tillgänglighetsanpassad för olika typer av människor, då det oavsett målgrupp kan förekomma personer med funktionsnedsättning.

Background: Low Price-Earnings ratio, low Book-to market ratio and low stock prices can give the impression that a stock is ?cheap?. Is it through systematic use of these portfolio strategies possible to beat the market index ? in other words does financial illusions exist? Purpose: To examine if the Stockholm Stock Exchange is an efficient market. Limitations: The efficiency is tested solely through the chosen portfolio strategies: low Price-Earnings ratio, low Book-to-market ratio and low stock prices.

In order to enforce Volvo?s own understanding and control of there own organization, as well as optimize the utilization of the in-house tow trains, the BRO methodology where created. The methodology where created from observations of the currents working environment, analysis of order data as well as a comparison with two similar producing factories.

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.

Background: The growth of the venture capital industry has given birth to new relations between investors and entrepreneurial firms. Venture capital firms are by definition investors serving as an active partner which implies a deeper relation between investors and entrepreneurs than has been the case previously. This new situation leads to a number of questions. Do venture capitalists really act as active partners with a long term interest in the venture? Do they add any value besides capital? How important is their influence in the portfolio company's decision making process? Purpose: The purpose of this study is to give a deeper understanding of the relation between venture capital firms and IT companies in the start-up phase.

En kvalitativ studie om några elevers lärande med portfolio som redskap och metodÅr: 2008 Antal sidor: 47I föreliggande studie är huvudsyftet att utveckla kunskap om elevers och pedagogers kvalitativt skilda uppfattningar av vilket lärande som elever utvecklar genom arbete med portfolio. I ett vidare syfte jämförs skillnader och likheter av uppfattningar.Bakgrunden sammanfattar kort vad portfolio kan innebära. Forskning kring reflektion, metakognition, värdering och bedömning kopplas som centrala element till portfolioarbetet.Studiens teoretiska utgångspunkt är den fenomenografiska forskningsansatsen och som metod har använts en halvstrukturerad intervjuform. Undersökningsgruppen innefattar nio elever i år 5- 6, samt fem pedagoger.Resultatet visar på kvalitativa skillnader i uppfattningar av vilket lärande som utvecklas hos elever genom portfolioarbete.

With this paper we intend to investigate what kind of benefits there are by adding commodity futures to a well-diversified portfolio. Since the last fifteen years the commodity speculation has grown tremendously, which partially can be explained by that commodities exposes the investor to certain factors other than an investment in equities. According to our calculations the commodity futures have outperformed stocks during our research period, which partially could be explained by the increasing demand of physical commodities in developing countries e.g. India & China (Akey, 2005). By constructing different portfolios consisting of equities and corporate bonds we could investigate whether our portfolios will benefit from commodity futures and how this will vary over different levels of risk.

I detta arbete görs en jämförelse av tre förskolors dokumentationsarbete, förmedling av dokumentationen till barnens föräldrar och huruvida internet används som hjälpmedel för denna förmedling. De tre förskolorna skiljer sig åt i sina pedagogiska utgångspunkter, där den ena är en Reggio Emilia-inspirerad förskola, den andra en montessoriförskola och den tredje arbetar uttalat med portfoliometodik för sitt dokumentationsarbete. Undersökningen görs med hjälp av observationer och intervjuer. Resultatet av studien är att förskolorna använder sig av liknande dokumentationsmetoder men med vissa skillnader som kan återkopplas till förskolornas pedagogiska inriktningar. Montessoriförskolan är den som skiljer sig mest genom att till exempel inte ha sitt arbete med portfolio tillgängligt för barn och föräldrar under förskoleperioden, medan den Reggio Emilia-inspirerade förskolan och förskolan med portfoliometodik liknar varandra i sina valda former av synliggörandet av dokumenterat material.

AbstractTitle: Level/Degree/Grade:Authors:Supervisor:Research question:Purpose:How the bank may improve its financial counselling ? A qualitative case study.Bachelor Thesis; Business administration; Corporate finance.Andreas A?strand, Anton Persson, Kristoffer Wedebrand.Hans Mo?rner.How may the bank improve its financial counselling to private investors using portfolio theory?Our purpose is to examine the advice, with basis in portfolio theory, the bank?s financial advisors provide to their clients, the investors, and how they can improve. If we can identify and point out areas of improvement in the financial counselling, we hope to raise the question and contribute with an improved financial counselling. Another positive effect we are hoping for is to improve the situation for the investors whereas all parties benefit from an improved portfolio selection.This study is conducted through a qualitative case study, where we used a deductive approach and collected our data through personal interviews.The conclusion that emerges is that the financial counselling could potentially be improved if financial advisors improve their knowledge in portfolio theory.The originality shapes through the opportunity to investigate a specific bank and because of that an opportunity to examine a specific case more thoroughly was created. Our thesis contributes with opening La?nsfo?rsa?kringar?s and other banks? eyes to how their financial counselling could be improved through new knowledge in portfolio theory.
