Den svenska regeringens förvirrade klimatarbete
The aim of this study is to clarify the Swedish government?s purpose of participating in theEuropean Union Emission Trading Scheme. Taking as its departure point state-centricinternational political economy this study presents three plausible hypotheses on what thepurpose might be. Either it is to promote consumers interests, or to promote the Swedishnational climate goal ?Reduced impact on climate?, or to promote the profit of Swedishcompanies.
Frekvensreglering i det nordiska kraftsystemet
Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.
Utvärdering av den bärande tegel- och betongstommen i en byggnad från år 1916
This Master thesis is about a postal- and telegraphic building in Eskilstuna, Sweden. The construction methods for the specific building and buildings in general from the same time are described. The purpose of the report is to describe the loads acting on the building and how it has been built and why it has been rebuilt during the years. After this, possibilities of reconstruction and adaptation for today?s demands can be evaluated.
Skotares bränsleförbrukning :
In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements.
The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials.
The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.
Likabehandling : Men på vilka grunder?
The Act Prohibiting Discrimination and Other Degrading Treatment of Children and School Students (2006:67) entered into force on 1 of April 2006. The purpose of this Act is to promote equal rights for children and school students and to combat discrimination on the five discrimination grounds of sex, ethnic origin, religion or other belief, sexual orientation or disability. This Act also has the purpose of combating other degrading treatment. According to the Act the organiser of the activity shall insure that there is an equal treatment plan that aims to promote the equal rights for children and school students irrespective of the five discrimination grounds. Discrimination is a result of the social norms which tends to exclude people who does not fit in and therefore considerers as being abnormal.
?Att man tagit dom på allvar är nog det viktigaste av allt?. Folkbibliotekariers uppfattningar kring bemötande utifrån ett allmänetiskt och yrkesetiskt perspektiv
The aim of this master thesis is to study the relationship between general ethics and professional ethics, to attain an understanding of which values that are given priority in the profession of the librarian regarding personal encounter towards library users. The posed questions are: How can fundamental ethical principles be understood through the view of public librarians? How can policy documents regarding librarian ethics be understood through the view of public librarians? How can policy documents regarding librarian ethics be problematized in relation to fundamental ethical principles? We used four focus groups consisting of public librarians. Three theoretical frameworks create the base of the analysis; four fundamental ethical principles, ethical guidelines for Swedish librarians and recommendations for Swedish librarians in the reference service. Three main issues emerge in the study; equalistic personal encounter where the principle of justice is emphasized but also problematized, library users? integrity which mainly coincide with the principle of autonomy and finally the librarian?s professional role which are being defined by librarian specific competence to refrain violation of the principle of injury avoidance.
Brevhantering av anmälningsärenden - vad blir effekten för djurskyddet?
In Sweden everyone has the possibility to report deficiencies in animal welfare they encounter. They report this to the county administration in their county and such a report is called a complaint case. Complaint cases are normally handled with animal welfare inspections, carried out by animal welfare inspectors from the county administration in the county where the animal keeper with reported deficiencies lives. The county administrations in Sweden receive a lot of complaint cases that differ in grade of how severe the deficiency is. The complaint cases are given priority by how severe the deficiency seems to be.
Undersökning av elkvalitet i distributionsnät med omfattande vindkraftselproduktion
The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.
Kinematisk och dynamisk modellering av den haptiska enheten TAU i sex frihetsgrader
The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.
End of line test : En studie av företaget Emotrons linjetestning i produktionen
Emotron is a company specialised in developing, producing and marketing equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes.The project is to look at Emotrons end of line test. The company has seen that at the final test-ing there is a bottleneck that restricts the outflow and prevents an increase in the number of tested products.The purpose of this project is to review how Emotrons end-of-line test works today and if there is a possibility to make the test more efficient in such a way that the quality is not at risk, while increasing the outflow of tested products.The projects first step is to look at and analyse what is causing the bottleneck at the end-of-line. When the analysis is complete, the next step is to review whether there is a possibility to solve the bottleneck and if so in what way can this be done. Emotrons most overall objective of the project is to increase the outflow of the number of tested products without jeopardizing the quality.An analysis has been made on frequency inverters, soft starters and shaft power monitors.
Regionalism som motstånd : Två latinamerikanska staters motiv att ingå i integrationsprojektet ALBA
The formation of sovereign states in regional blocks has become an essential feature in the world system. Therefore, the purpose of this paper is to investigate which motives and driving forces that affect the creation of projects of regional integration outside Europe and the Western World. By choosing the Latin American project of integration ALBA (the Bolivarian Alliance of the Americas) as a case of regional integration outside Europe and the Western World, the study investigates the motives expressed by the most prominent actors of the project, Venezuela and Cuba. ALBA is chosen as a representative and a unique case and through the consumption of the gramscian and the realist approaches, the essay defines two motives that affect the creation of projects of regional integration. As a way of investigating the actors? motives, the paper studies political statements, especially those of the Venezuelan president Hugo Chávez, and official positions expressed in central documents and declarations.
How Does Ego Depletion Affect Moral Judgments and Pro-social Decisions?
BACKGROUND: Today?s societal changes, including high rate of change and increasing information flows, are increasing the demand on the individual mental capacity. It becomes increasingly difficult to analytically process all the different dilemmas and everyday decisions as individuals have a limited mental capacity available to make these decisions. Thus, it has been suggested that ego-depleted relies more heavily on intuition, which is less burdensome, when making decision. However little is known about to what extent intuitive decisions differ from analytic.
En studie av retentionen i floden Oder och dess avrinningsområden, Polen.
Nutrient enrichment is the main cause of the increasing eutrophication process in the Baltic Sea during last century. A prerequisite counteract this process the load of nutrients to the Sea must be investigated. The large contribution of nutrients to the Sea is caused by emission from the rivers within the drainage basin. For the total emission of nutrient into the Sea the retention process in the rivers has big influence. This process in the river system has been assumed as a not important part of the nutrient cycle.
