Denna rapport beskriver det examensarbete som utförts på Calix AB under vårterminen 2013. Calix AB tillverkar värmare för bland annat batteri och kupé till fordonsindustrin. Uppdraget i detta examensarbete var att göra en omkonstruktion på BEV-heatern (Battery Electrical Vehicle) som är en batteri- och kupévärmare till el och hybridfordon. Problemet med den nuvarande konstruktionen är att den bygger på delar från äldre värmare till fordon med förbränningsmotorer, samt att konstruktionen inte är lämplig för produktion i större serier. Krav som Calix AB hade var:Integrerat ChassiMinimera tryckfallUnderlätta montering och tillverkningUppfylla standarder satta av fordonsindustrinKunna monteras ?in-line? i fordonetFör att kunna genomföra projektet var vi till en början tvungna att få kunskap om hur den befintliga BEV-heatern fungerar.

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

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.

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.

Arbetsterapi är ett ämne som framhäver hälsa och välmående genom aktivitet. Det huvudsakliga målet som arbetsterapeut är att möjliggöra för personer att delta i aktiviteter i det dagliga livet. Virtual Reality är en simulation där datorgrafik används för att skapa en tillsynes realistisk miljö och denna värld är inte statisk utan integrerar med användaren. Syftet med denna litteraturstudie är att kartlägga hur och varför Virtual Reality kan användas av arbetsterapeuter. En systematisk litteraturstudie genomfördes och efter databassökning uppkom 14 artiklar som via en manuell sökning kompletterades med ytterligare 5 artiklar.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

Syftet är att evaluera Baselramverkets riskreglering i en konjunkturcykel med hänsyn till Östersjöregionens storbankers systemviktiga funktion.Studien antar främst en kvantitativ ansats i de två första delarna, nyckeltalsanalysen och buffertsimuleringen men även en kvalitativ ansats antas i den tredje delen, intervjuer. Studien utgår från teorierna om Basel I och Basel II, nyckeltalsteori samt från tidigare forskning.Resultatet i studien består av nyckeltalanalys och simulering av åtta, i Östersjöregionen verksamma, bankers nyckeltal och buffert under 21 år samt sex djupintervjuer med representanter för såväl banker som regulatorer. SlutsatserAtt det inte finns något samband mellan Baselregleringens kapitaltäckning och bankernas risk eller konjunktur, att riskvägningen tenderar till att vara godtycklig och har större påverkan på buffert än Baselregleringens kapitaltäckning samt att mer transparens behövs i bankerna tyder på att Baselregleringens kapitaltäckningskrav i mycket liten utsträckning visar Östersjöregionens storbankers faktiska risk..

Purpose: The purpose of this thesis is to test for the existence of Capital Structure Arbitrage oppertunities in the equity-credit markets. Methodology: The mispricing of Credit Default Swap contracts are calculated and used as input in an Equity-Credit market trading strategy. The returns are then evaluated with a modified Value-at-Risk simulation. Theoretical perspectives: A Merton-based structural model, CreditGrades, is used for credit pricing and a mispricing-convergence trading-strategy between the credit and equity markets is implemented. Empirical foundation: Daily quotes for the Credit Default Swap spread of 37 European firms were collected for a period of two years, as well as equity-prices for the same period and the previous two years, used for model calibration.

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.
