Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent. 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.

Bachelor thesis ? ControllerEconomics, Linneaus UniversityTitle:From data to information ? a case study at Södra Cell Mönsterås Authors:Sofie Gotting, Renée Lundberg and Emma Molin Tutor: Anders Jerreling Examiner: Fredrik Karlsson In Sweden, the process industries employs nearly 600 000 people and it accounts for about 60 percent of the country's net export. In many industries today, there is a growing emphasis on calculations. They are used to manage and control the activities in today?s organizations, one of these industries is the process industry.

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

This thesis is conducted together with the environmental- and health department in Halmstadcommunity. The thesis is about allowance of bedding and water supply for pig farms inHalmstad community. These farms are chosen randomly from all of the pig farms inHalmstad community. It includes inspection of 27 pig farms and writing of a report. Duringthe inspections I study the amount of bedding, what kind of bedding, water supply andinjuries like lameness, shoulder-bone sore, ear-, flank- and pig tail biting.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Purpose:The background to this study is an upcoming sale of a property. Owner of the property is currently city of Gävle and tenant is Jan Ekroth who runs the hostel Gamla Gefle in the buildings belonging to the property. The purpose of this study is to investigate whether Gamla Gefle AB has the financial ability to acquire the property and if it can be defended in a commercial plane.Method:In this study a qualitative method has been used, in which empirical data has been gathered from interviews and financial data taken from annual reports. These empirical data have been put against our theoretical framework and led to our analysis. In the analysis, cash flows and discounted future values have been calculated to determine the outcome of the investment.Results & conclusion:The study reaches the conclusion that the hostel Gamla Gefle should complete its acquisition of the property, in spite of an decrease of the annual cash flow.

This master thesis was conducted at Motala Wire Works Ltd (MWW) in Motala during the autumn and winter of 2007-2008. The thesis named ?Future layout of Motala Wire Works? focuses on making a better planed layout for the factory, which also take in to consideration future changes.Motala Wire Work produces wire mesh products of varying sorts for the white goods industry. The factory was started by Electrolux during the 1950?s.

To conclude this year?s introductory course in Mechatronics the students, in groups of 6,constructed a prototype based on the technical requirements established by the course teachers.This year they consisted of the following: two wheels only, active balancing, remote controlledand able to stop when crossing a pre-determined marker on the ground. The project lasted for 7weeks and the result is a working prototype and this report.The report reviews the chosen solution, subsystems and the finished prototype as well assuggestions for improvements, discussion and analysis.The prototype constructed embodied most of the group?s earlier individual technical specialtiesand consists of the following: a flywheel for balancing, ultrasound for angle measurement, areflective photomicrosensor to detect the marker and Bluetooth for the hand control..

Syftet med vår undersökning var att undersöka om extrem-/äventyrssport hade en plats i kursen idrott och hälsa A. Vi valde att skicka ut förfrågningar till 20 skolor i Malmö och grannkommunerna, av dessa fick vi svar från tio och endast fyra ville delta i undersökningen. Detta gjorde att vår undersökning omfattar fyra intervjuer med utbildade idrottslärare på fyra olika gymnasieskolor i sydvästra Skåne. I vårt resultat kom vi fram till att tre av lärarna hade extrem-/äventyrssport vid ca fem lektionstillfällen per termin, och en hade inga lektioner alls med denna typ av aktivitet. Det var många faktorer som spelade in när lärarna beskrev varför de inte hade så många lektionstillfällen med anknytning till extrem-/äventyrssport bland annat tid, resurser, skaderisk, engagemang och förutsättningar i närmiljön. Alla lärare vi intervjuade hade en positiv inställning till extrem-/äventyrssport i skolundervisningen och skulle gärna vilja få in fler lektioner med denna form av aktivitet, eftersom det hjälper att stärka elevers självkänsla, ger en allsidig träning och är ett bra verktyg för teambildning. Tre av dem såg det som väldigt viktigt att idrottsundervisningen i skolan följde med i utvecklingen, anammade de nya aktiviteter som ungdomar sysslar med utanför skolan och att extrem-/äventyrssport hade blivit ett stort fenomen i samhället.

Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.
