This report presents an investment calculation based on an assumed initial investment of a new saw line to an existing sawmill. In order to get as close to reality as possible, we have received data material from northern forest owners who recently made an initial investment in their sawmill in Kåge. In order to calculate and evaluate investments are several different methods, but we, we have chosen to use the discounted cash flow method. The method sums up with the help of a fixed cost of capital together with any future costs and revenues, thereby giving a present value of the investment. We also do a sensitivity analysis to examine how selected factors affect the investment research they change. The study is carried out to a fictitious investment, and therefore the result should not only be studied as a result of the figures. The purpose of this study was that with the help of an investment calculation studying the profitability of a hypothetical investment, and by means of a sensitivity analysis to study the sensitivity of investment to changes. The result demonstrates that the calculations according to the present value method requires a lot of information of the prospective investment.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

This document presents calculations of adjusted GDP based on satellite household accounts for the year 2001 with the purpose to compare adjusted and official GDP for Sweden, Germany, Estonia and Finland. Household production in each country is estimated using time use survey data from Eurostat and a monetary value is estimated using average wage (after taxes) for each country. The results indicate that the value of household production using this methodology increases GDP with between 42% (Finland) and 55% (Germany) compared to official GDP statistics. A comparison of GDP/capita between the countries included in the study shows that the GDP/capita in Germany increases more that the other countries due to the relatively high proportion of time used for household production (mainly German women) combined with a high average wage. In fact, the results show that Germany has higher adjusted GDP/capita than both Finland and Sweden (but Germany has lower GDP per capita when official statistics is used for the comparison).

Title: Pricing of IPO:s on the Swedish stock market Authors: Mikael Gustavsson Martin Kvist Henrik Wannberg Tutor: Anders Hederstierna Problem: There are certain sets of problems for underwriters when they are pricing potential stock-exchange companies. The problem partly consists of estimating the demand at an IPO and also to accurately value the business in comparison to the market. To set the price per share is problematic, since the company carrying out the public offering wants to optimise the amount of capital at the same time as they want the share to be subscribed in full. If the IPO would not be carried out, it could cause harm to the position of the underwriters. Purpose: To investigate whether underpricing exists associated with IPO:s on the Swedish market during the period 1995-1999.

With today´s power uprates in BWR reactors the bundle lift force has become aproblem. The lift force is calculated using a best estimate approach and the resultfrom the calculation should pass the existing lift force margin. Lift force margin isdefined so that the lift force may not exceed 80 % of the fuel weight. The margin issupposed to cover all the uncertainties that exist in the lift force calculations.However, no uncertainty analysis has been conducted to quantify the uncertainties.In this report the uncertainties in the lift force model have been quantified. Each inputparameter to the lift force model which has been assumed to have an uncertainty isassigned a probability distribution.

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.

Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

This paper investigates the methods used by teachers when teaching elementary mathematics to children with Swedish as their second language. The original mathematical terminology derives from Latin, Greek and Arabic, this terminology is not of great importance in this paper, the everyday language spoken in elementary classes when teaching mathematical concepts and calculations to younger children is. The use of everyday language is an advantage for children with Swedish as their second language as mathematical problems presented in a more plain language is easier to comprehend and solve than problems in mere numerals. Special teachers in home language classes often have the task of clarifying the mathematical concepts, introduced to the children during mathematical lessons, in the pupils first acquired language. A qualitative method was used in this study.

Design of a house requires knowledge of both technology and economics. Heating and ventilation shall be designed, costs are calculated and estimated and requirements must be fulfilled. Which heating system is to be elected is also a difficult choice, especially with rising energy prices as a factor.The choice of energy system is not always given, because it depends on several factors. Below is a comparison between district heating, geothermal heat pump and electric boiler from an economic standpoint. In a previous report appears district heating and geothermal heat pump as the best options.

The shooting sport is one of the most widespread sports in the world and it isbeing practice in most countries. Based on their own experiences, in competition -and hobby shooting, the client M4Solutions found a demand and need for ashooting target that is manufactured in Sweden.The purpose of the project has been to develop, with the help of Marcus Walldén,two shooting targets from idea to finished product. These two shooting targets,Plate Rack Target and Dueling Tree, would each be equipped with a mechanicalresetting system but will in the future have the ability to be provided with anelectronic resetting system.The project from the client was divided into two theses. One of these two, writtenby Marcus Walldén, focused on the tripod parts and the overall design work forboth Plate Rack Target and Dueling Tree. The thesis that is presented in thisreport have focused on resetting systems, the design of protective plates and otherperipherals for both shooting targets.This work has primarily been in CAD environment where design, constructionand development has been given free rein.
