Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

The purpose with the essay is to illuminate four former clients? personal stories about the meeting with the authority in the Swedish welfare system and the institutionalization theywent through. The questions being asked in the essay focus on communication, the relationship concerning power and the former clients attitude towards the institutionalization as a treatment. Four interviews were held with former clients who were institutionalized sometime between the ages of 15-25. The results were then analyzed by theories focusing on communication as a way to gain power and how social interaction may influence the individual attitudes towards authorities.

How effective is consumer power? Can consumers regulate corporate behavior?And if so is the case, could the mechanisms where consumers regulate corporatebehavior have any democratic value to contribute with? These are the questionsthat this master's thesis comprehends with. The purpose of this writing is toconstruct a theory of consumer power that is compatible with democratic theory,this in order to contribute to the ongoing discussion within the discipline ofpolitical science about the third democratic transformation. A discussion that hasbeen actualized due to the democratic deficit created by the growing corporatepower and the shift of power from state to private enterprises. Besides showingfor a parallel between the democratic mechanisms that exists in the relationbetween citizens and state on the one hand, and the consumers and corporationson the other hand, this paper argues that consumers do have a great potential inregulating corporate behavior towards a higher social responsibility andawareness.

Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.

From the mid 19th century to the early 20th century about 1.2 million Swedes left Sweden for a new life in America. Three parishes in Örebro län is at the centre of the research of this essay. The time span of this essay ranges from 1856-1915, divided into three periods; 1856-1870, 1881-1895 and 1901-1915. The main objective has been to compare the three parishes with each other, with Örebro län and with Sweden. What I have wanted to examine has been the following: How many people from each parish emigrated during each period? How many were men, women and children up to the age of 15? In the analysis part of the essay the results were compared parish with parish, and with Örebro län and Sweden.The analysis showed that the emigration of three parishes is commensurate with the Swedish emigration history.

Wind power is becoming an increasingly important source of energy. There are several national and international goals set to increase to amount of renewable energy, and in order to meet these goals, the wind power production plays an important part and the establishment of new wind power farms are required. The Swedish national project Riksintresse Vindbruk has appointed areas in Sweden suitable for wind power, mainly when looking at the physical wind conditions of the area. In this study, I aim to define suitable areas for wind power establishment in Norrbottens län. In order to reach this goal, a critical regional method was developed and completed using GIS.

AbstractThis paper is a comparative study of the final reports of the Norwegian and Danish power studies performed in 2003. While the Danish study found that democracy is thriving, the conclusion of the Norwegian power study was that democracy is in a crisis. The purpose of this paper is to find explanations to why the studies in two Nordic countries arrived at such different results.Methodologically, the paper consists of an ideological text analysis and critical analyses of the discourse. In order to study how the results of the power studies can differ so considerably, the following aspects have been surveyed; 1) external contexts (government inquiries); 2) work process (the researchers? background, role and co-operation); 3) the problem areas and themes studied; and 4) power perspectives.

The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.

This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.
