This is a report written for an examination project C-level, on the subject of energy. The examination project is a product of the FVB Sweden AB (district heating bureau). It started with a meeting with Stefan Jonsson FVB Sweden AB, were he explained the content of the project, and from this a presentation of the problem was made. The problem that needed to be solved was how they could control the valves in the system to provide heating to everyone in the system. The valves are often oversized so the pump in the heating plant would have to be enormous to be able to provide enough flow to be sufficient, if everyone in the system had there valves fully opened. I came up with two solutions to the problem, one was a wireless network that could keep track of the valves and the other solution was an extra sensor that was placed on the radiator.

Fusion och Organisationskultur : En studie på Skruf Snus AB
Mergers between companies has become more and more common in Sweden and in the rest of the world with the motive to increase the competitive strength in the current markets and has an important role within organisational development of companies. When organisations merger there is not only buildings and objects that are put together but also their individual organisational structures, people, values and cultures. This can be a difficult process and can affect many people in how they think conscious as well as unconscious, feel and react.The purpose of this thesis is to gain a deeper understanding of how employees are affected following a merger when changes in the organisational culture come up, and how these changes are expressed.This thesis is delimited to investigate only one company, Skruf Snus AB and only focus on their business and employees in the region of Stockholm. The thesis contains a qualitative investigation with semi structured interviews that has been carried out with eight employees at Skruf Snus AB. The thesis is partly based on a model of Schein which describes the different levels in organisational culture and partly on some theories about reactions to change in relation to the integration between the employees following a merger.The results of the investigation indicate that with a merger the whole organisational culture is affected and therefore also the employees.
Signal- och bildbehandling på moderna grafikprocessorer
En modern grafikprocessor är oerhört kraftfull och har en prestanda som potentiellt sett är många gånger högre än för en modern mikroprocessor. I takt med att grafikprocessorn blivit alltmer programmerbar har det blivit möjligt att använda den för beräkningstunga tillämpningar utanför dess normala användningsområde. Inom det här arbetet utreds vilka möjligheter och begränsningar som uppstår vid användandet av grafikprocessorer för generell programmering. Arbetet inriktas främst mot signal- och bildbehandlingstillämpningar men mycket av principerna är tillämpliga även inom andra områden.Ett ramverk för bildbehandling implementeras och några algoritmer inom bildanalys realiseras och utvärderas, bland annat stereoseende och beräkning av optiskt flöde. Resultaten visar på att vissa tillämpningar kan uppvisa en avsevärd prestandaökning i en grafikprocessor jämfört med i en mikroprocessor men att andra tillämpningar kan vara ineffektiva eller mycket svåra att implementera..

Algoritmer för objektdetektering i SAR och IR-bilder
The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures.
Byggplatsnät : Att etablera ett spänningsfritt stomnät
Geodata finns idag tillgängligt via geodataportaler runt om i världen. På dessa geodataportaler beskrivs datamängder och tjänster som kommer från olika myndigheter. Geodatasamverkan har uttryckt intresse för att kunna beskriva realtidsresurser på dessa portaler med hjälp av metadata. Utifrån ett samarbete mellan SMHI och Lantmäteriet har denna studie tagits fram där en dynamisk realtidsresurs från SMHI testas beskrivas med Geodataportalens nuvarande struktur. Befintlig litteratur har undersökts för att presentera en bakgrund.

Sensorfusion för undervattensrobot i kärnteknisk miljö med Kalman filtrering
WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.
Fusioner - är två plus två lika med fem?
Inom läkemedelsbranschen har fusioner och samgåenden blivit allt vanligare för att uppnå synergieffekter i form av kostnadsbesparingar och intäktsförbättringar. Trots positiva synergieffekter på kort sikt är de långsiktiga fördelarna långt ifrån givna. Det har visat sig att flertalet fusioner misslyckas på grund av att marknadseffekterna vid en fusion inte undersökts eller tillräckligt ingående beaktats. Leder en fusion mellan två likartade företag till ökade marknadsandelar?Fusionen mellan Astra och Zeneca tillkännagavs 1998, och är en av de största företagsfusioner som genomförts i Sverige.
En simuleringsmiljö för distribuerad navigering
This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.
Prototyputveckling av digitalt styrsystem för torkskåp
Nimo Verken AB is the leading producer in the Scandinavia of drying cabinets. The construction has, with small changes, been the same since the 70s with a thermostat and a timer as controlling system. There was a wish to develop a modern cabinet which showed remaining time on a display and with energy saving functions.In this report we go through how it is possible to implement a digital controlling system, where remaining time is shown on a display and where it is possible to choose a preset ?program?.The report first presents the fundamental theory for a PIC, where we describe the different registers, how interrupts are handled, the internal clock function and how data is sent to control the different parts of the construction.Next the report presents and describes the new hardware that is needed, such as the encoder, the temperature sensor and the display.After the theory we describe how the program in the PIC may be drafted. Last in the report we have the result of the tests of the temperature variations and the accuracy of the time..

Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning
There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).
