The avowed aim in this project was to see how the Swedish egg production is today. My first question was if the Swedish egg producers egg production turn a profit. I have done five after calculation at five different egg producers with different systems from case to case. The difference has been the living system, the fodder and the egg price. They made a report in Uppsala, Sweden (Hoffman & Andersson, 1996), where the look forward to a Swedish cage ban and made calculations after that coming ban. After that they lift the Swedish ban of cages and the egg producers could invest in new cages who called the decorated cage.

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

Background: In 1999 the Swedish pension system was reformed with an aim to create a stable and high return on pension assets. First, Second, Third and Fourth general pension funds, hereby referred to as AP1-AP4, had an important part in the reform. AP1-AP4, also called the buffer funds, was assigned to secure long-term, big parts of the pension capital. The funds objective is by law, to manage the fund's assets in a manner that provides maximum benefit for the state pension. The funds will also invest pension assets with an overall low level of risk while achieving a sustainable high return.Aim: The purpose of this study is to investigate whether the First-Fourth AP-Funds is meeting its objectives regarding risk and return according to Swedish law.

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Dagens teknologiska samhälle ställer höga krav på människan, bland annat gällande att processa information. Vid utformning av system tas det numera vanligtvis hänsyn till människa-datorinteraktionen (MDI) för att erhålla en så hög användbarhet som möjligt. Affektiv Informatik, som är ett utvecklat sätt att förhålla sig till MDI, talar för att utveckla system som både kan uppfatta och förmedla emotioner till användaren. Fokus i rapporten är hur ett system kan förmedla emotioner, via dess färgsättning, och därmed påverka användarens emotionella tillstånd. En kvantitativ undersökning har utförts för att ta reda på hur färger kan användas i ett system för att förmedla känslouttryck till användare.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

Permaculture is a design system that aims at developing sustainable human settlements and self-maintained agriculture; it may also be used for community planning. The design system of permaculture aims at mimicking a natural ecosystem; this gives the advantage to make use of all the connections and mechanisms that exist in such a system.The purpose of this bachelor thesis was to compile and spread scientific information regarding five different themes within the areas of ecology, environmental science and permaculture. This was achieved through cooperation with the permaculture inspired Ecovillage Suberbyn in southern Gotland. Information about the central parts of a permaculture ecovillage was used as material for a series of signposts that will be located around the ecovillage Suderbyn. The five selected themes were: An overview of permaculture, The forest garden, The pond, Composting and The use of human excrement and urine..

The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

Innehållshanteringssystem används för att hantera innehåll och det finns många system att välja på. Detta arbete har fokuserat på fyra innehållshanteringssystem för innehåll på webben. Det är systemen Drupal, Joomla, Polopoly och Wordpress. Syftet var att inhämta teoretisk och praktisk kunskap om dessa system och besvara huvudfrågeställningarna om vilka inbyggda funktioner som finns, hur anpassbara systemen är, hur de olika systemen är att arbeta med för en utvecklare och hur anpassade systemen är för webbplatser med mycket trafik.Det jag kom fram till var att Drupal är ett mycket väl utbyggt och omfattande och anpassbart system där det går att utnyttja mycket tredjepartstillägg och anpassa den efter egna önskemål. Joomla är ett system som innehåller mycket inbyggd funktionalitet och det finns mycket tredjepartstillägg att tillgå, men anpassbarheten är dålig.

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.

Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

Ett CRM system ger fördelar för ett företags förmåga att bygga varaktiga kundrelationer. Små och medelstora företag är dock tveksamma till att investera i sådana system. Resurserna för att dels investera i och sedan effektivt förvalta systemen fattas ofta i företagen. Implementationerna av systemen drar dessutom ofta ut på tiden. Modellen Software as a Service har under 2000 talet vunnit stora landvinningar.
