Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys
This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .
Familjen & Döden : föräldrars förhållningssätt till sina kvarvarande barn
The aim of this study was to explore the role of death in the Swedish family. How do parents and families cope with the loss of a child/sibling? How do the remaining children in a family fare after loss of sibling? The study was caused out partially through a selective review of the literature on children loss in families and partially through interviews with families who had experienced death of a child. The results were analysed with help of Family system theory, Emotional theory and with an Esoteric perspective. The findings of the study were that although families do eventually cope with the situation the majority is struggling to adjust.
All makt utgår från Väst : En kritisk diskursanalys av Afghanistans politiska rekonstruktion
Syften med denna uppsats är att studera vilka normer och värderingar som ligger till grund för rekonstruktionen av Afghanistans regeringsinstitutioner, samt vilka strukturer som gör att dessa normer är de hegemoniska globalt. I mitt analysarbete har jag framförallt använt mig av Norman Faircloughs textnära kritiska diskursanalys och ?Världssamhällemodellen?, där begrepp såsom legitimitet och hegemoni står i fokus. Som analysunderlag ligger ?Afghan Bonn Agreement? samt tre resolutioner från Förenta Nationernas (FN) Generalförsamling.Det finns idag tydliga normer som styr vad som anses vara ett legitimt styrelseskick.
En komparativ studie av svensk och lettisk arbetslagstiftning i skuggan av Laval-målet
After the last European Union expansion the east European countries became members of the European Union. This meant that they would become apart of the Schengen agreement and that they would be able to travel, live and work anywhere in Europe. This came as a shock tothe Scandinavian trade unions that were worried that work migration would escalate, and that it would lead to social dumping, which would make the working conditions worse for the native workers. .The Swedish labour market is build up by the principal of negotiations. The evolution of the labour laws comes from the rules and regulations of collective agreements.The Lex Britannia principal was made to regulate the working conditions for guest workers in Sweden, by making it possible for trade unions to take industrial action against foreign companies to make them sign a Swedish collective agreement.Even though Swedish labour law includes an obligation to maintain industrial peace it is not valid for foreign companies.
?Jag är en av de få som blir lycklig...? - bibliotekariers attityder och förhållningssätt på fem folkbibliotek till statens distributionsstödda titlar.
The purpose of this master?s thesis is to study attitudes and standpoints among a few librarians towards literature with state supported distribution provided by the Swedish Arts Council. By qualitative interviews with librarians at five different public libraries, the thesis examines which attitudes that flourish concerning the titles, how the circular of books is treated, where the titles belong on the literature map and if the system is producing a standardisation of this literature and if the conception of quality is relevant. We also study how the librarians relate to intentions of the Swedish Art Council with the distributed titles and how they regard their availability. Our theoretical framework is based on Hans Hertel?s model of five literary circulations and Theodor W.
För att vara den bibliotekarie som krävs : En undersökning av bibliotekariers läsvanor
The aim of this thesis is to study the reading habits of Swedish librarians visualized by librarians from Götabiblioteken ? a collaboration of 14 public libraries in mid-Sweden ? focusing on the reading done on their spare time, even if work-related. We started with a survey sent out to 74 librarians in October 2013, answered by 56, and followed up by interviewing 7 of them in November.We tried to answer these questions:To what extent does the working librarians read on their spare time compared to before they started working?What literature do they read, now compared to before they started working?To what extent does their perception of what they should have read affect their private reading?In what way does a librarian in the beginning of their career differ in reading habits from the reading habits of a librarian with many years in the profession?The result of our study shows that most of the librarians read as much or more than before they started to work. They are more selective in their choice of literature and are affected by their work in it in different ways.
Anslutning av vindkraftpark till befintligt nät
Detta examensarbete är utfört på Fortum Service AB samt Fortum Distribution AB iKungsbacka. När en förfrågan om anslutning av en produktionsanläggning kommer tillelnätsägaren är det elnätsägarens skyldighet att göra beräkningar om huruvida nätetbehöver förstärkas eller inte. Uppgiften för examensarbetet var att se på vilket sätt enplanerad vindkraftanslutning kan påverka elkvaliteten samt att se på kabelsträckningar.Även alternativa anslutningar och grov kostnadskalkyl skulle presenteras.För elkvalitetsberäkningarna användes AMP och ASP som är riktlinjer för anslutning avproduktionsanläggningar till elnätet. Data om kraftverken följde meduppdragsbeskrivningen.Det presenteras olika kabelsträckningsalternativ i rapporten. För de olika sträckningarnagörs även en jämförelse mellan konstruktionsspänningsalternativen 12 och 24 kV.
Sveriges potential för elproduktion från takmonterade solceller : Teoretisk, teknisk och ekonomisk analys
The Swedish potential of electricity production from roof mounted solar panels has been determined in three steps: accessing the existing roof top areas, simulating the amount of electricity solar panels can produce on these areas and finally analyzing how large the necessary economical change is to make the solar cells profitable.The total existing amount of roof top areas are 319 square kilometers and the area distribution follows the distribution of people. This leads to an installed power of 47,9 GW which are expected to produce 49,0 TWh electricity per year. If the quality of the electricity is prioritized the highest the power is reduced to 3,7 GW, generating 3,8 TWh yearly, but if the hosting capacity is calculated from Sweden?s total electricity need, the capacity is 42 TWh per year.Today, solar panels are not profitable in Sweden for houses, even though there is a subsidy of 35 % of the investment costs, discounted in 25 years. The profitability is calculated with a cost of capital of 5 %, a price on electricity of 1 SEK/kWh and an investment cost of 20 SEK/Wp.
Värderingsprocesser för bedöming av siginfikanta aspekter i företagsledning för hållbar utveckling
The use of environmental management systems, and objectives-led corporate management have become a widespread phenomenon today. Identification and assessment of an organisation?s significant (environmental) aspects is crucial within this work. Identification and especially assessment of significant aspects is often considered as a problematic step in many organisations. There are no generally accepted methods how to undertake this crucial step.
Viktiga egenskaper hos framgångsrika svenska skolskogar :
A substantial part of the Swedish outdoor education is being practiced in so called ?school forests?. The concept school forest was first introduced in the 1980?s by the organization Skogen i Skolan. The definition of a school forest is an area that is being used for educational purposes, over which the school and the land owner has reached an agreement of how the school may utilize it.
Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power
Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..
Utvärdering av en Magnetic Harmonic Traction Drive
In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.

It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.
Beteende på offentliga platser
Several theoretic and environmental psychological models establish a connection between the environment and the reactions of humans and the research support that there is a mutual influence between individual, environmental and behavioral factors. You often assume that a person both can influence and be influenced by the surrounding environment. This is evident, but it is less obvious how a given physical design influence people?s immediate behavior in the city. The aim of this study was to investigate if the physical design of a place influences people in an urban environment and to investigate how the behavior is influenced.
