Investeringskalkyl för en ny såglinje : en rapport om investeringskalkylering
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.
Miljöpåverkan av äggproduktion : En jämförelse mellan Lilluns ägg och andra svenska äggproducenter
The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.
Kvantifiering av osäkerheter i lyftkraftsmodellen
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.
Studie av flöden på en dagkirurgisk avdelning
Sepsis (blodförgiftning) är ett allvarligt tillstånd och behöver en snabb diagnos som fastställs genom blodprov. Blodprov från hela Stockholms Län skickas till Karolinska Universitetslaboratoriet (KUL) för analys, där biomedicinska analytiker och läkare fastställer arten på infektionen och beslutar vilken antibiotikabehandling är optimal.Målet med arbetet var att identifiera eventuella problem som skapar flaskhalsar hos Klinisk Mikrobiologi i Solna som är en del av KUL. Därefter skulle lösningsförslag framföras och möjligheten att införa blodprover i ett nytt automatiskt system, BD Kiestra Total Lab Automation undersökas.Verksamhetskedjan för laboratoriet analyserades genom observationer och läsning av metodbeskrivningar.

BD Kiestra TLA behandlades separat med en systembeskrivning, följt av de problem som finns för införandet av blodprov och hur dessa problem kan lösas..
Överföring av kunskap : från spel till verklighet
Denna undersökning behandlar spel i kontext till lärande och matematik. Genom att gestalta ett spel undersökte vi, författare hur olika designval kunde påverka lärande. Målet var att spelare skulle lära sig genom situationsbaserat lärande och där genom få möjlighet att överföra sin kunskap till sitt vardagsliv. Undersökningen hade sin utgångspunkt i ANT (actor-network theory) som användes som metodologi för att analysera och reflektera över de val som gjordes. MDA (Mechanics Dynamics Aesthetics) användes som ett ramverk för att utveckla själva gestaltningen.
Klimat i djurtransportbil med slaktgrisar sommartid : jämförelse mellan naturlig och mekanisk ventilation
SAMMANFATTNING
Uppskattningsvis transporteras 171 miljoner grisar inom EU varje år, varav ca 3,5
miljoner i Sverige. Grisarna kommer, under hela förloppet från förflyttningen från box i
stallet till bedövningen i slakteriet, att utsättas för stressande moment. Orsakerna är
bland annat omgrupperingar, nya miljöer, vibrationer i bilen samt, speciellt under
sommaren, värmestress.
Temperaturen i djurtransportbilen är en nyckelfaktor som dessutom kan förstärka
effekten av andra stressorer. Lastning i höga temperaturer ökar risken för värmestress.
Värmestress innebär att djuren får allt svårare att avge sin värme. Även den relativa
luftfuktigheten har betydelse, framförallt vid temperaturer över 30°C.
Det är ventilationen i transportbilen som ska transportera bort värme och fukt från
bilen.
Kapitalförvaltarnas arbetsmetodik vid förvaltandet av den diskretionära potföljen
Background: The devolopment in the exchange market has attract a large number of investors. The information flow is extensive and it might be hard to follow the dynamic market. Some investors therefore choose to place their capital in a stock portfolio which is manged by a professional firm with no influence from the capital owner, this management is called discretionary managing. Purpose: the purpose of the thesis is to examine the working methods and the rationality regarding the management of the discretionary portfolios. The purpose is also to try to examine whether there is a relation between the selected risk, return and fees.
Utvärdering av AOT för ett pilotskaligt, recikulerat akvakultursystem för fiskodling
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

We decided to base our study according to the following two questions:1. What are the underlying reasons why there has been such a big trend with arena project?2.
Beslut om investering i alternativ energi : en studie om hur lantbrukare fattar beslut vid investering i halmpanna
Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

Effektivisering : En utredning om åtgärder på en industrifastighet
AbstractDelta Terminal owns an outdated industrial building which they now rent out to businesses. This property currently has a high energy con-sumption and therfore it is desirable to improve the efficiency. In ordet to reduce the energy consumption within the industrial building enve-lope, the heating systems and lighting are being investegated. A good building envelope emits less heat and thus reduces the energy consump-tion. An energy audit is a tool used to determine the energy loss.
Carbon Critical Masterplanning tool : klimatpåverkan från samhällsplaneringsprojekt
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case.
A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety
of combinations for energy supply to the future area. The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle
