Elmätarens roll i framtidens elnät : Ett samarbete med Sweco Energuide AB och Mälarenergi Elnät AB
The initial aim of the roll out of smart electricity meters in Sweden was to allow remote readings of the households? monthly electricity consumption for billing purposes. Since then the transition towards a smart grid has become a more prioritized matter. In the roll out of next generation smart meters more attention is therefore given to how the Distribution System Operator (DSO) can benefit from the meter through different smart grid applications. This study uses a qualitative research method to identify three general fields of application and 15 specific concepts corresponding to ways in which the DSO can create added value from the information provided by the smart meter.

VSM och 16 förluster
With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.
"Masada ska aldrig falla igen!" : En studie om Masada som en israelisk nationalmyt under 1900-talet
??Masada shall never fall again!? A study about Masada as an Israeli national myth during the 20th century? by Sara Tibblin. This essay is about the Israeli national myth of Masada, a cliff in the Negev desert that was the setting of a collective suicide in 73 AD, at the end of the Jewish uprising against the Romans. This story has later been rediscovered and has during the 20th century become a national myth in Israel. This essay will examine how the national myth of Masada has been used in different contexts in Israel during the 20th century and which part it has played when it comes to the national identity of Israel. My findings have afterwards been explained with help of Eriksens theory regarding national myths from the book Historia, myth och identitet (History, myth and identity) (1996). .
Hur barn i årkurs 3 uppfattar syftet med Nationella provet
This is a study of the national test in 3rd grade. The national test is obligatory and is conducted in 5th and 9th grade, but since the spring of 2009 the tests also become mandatory in 3rd grade. The case study of this research is to find out how children in 3rd grade perceive the purpose of the national test. The survey should also clarify how students think and feel about the national test, and how they feel before the national test and after they have finished writing the test. Has the test positive or negative influence on children? The survey will also show how much teachers clarify what the significance of the national test is for the students.
Automation i Distributionsnät
As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.

Gridens svar på överlevnad : -en studie om revisorers beaktning av fortsatt drift
An auditors? job is to review the company's figures and, as an independent part, give an accurate picture of its financial situation. Auditors have to relate to ISA where ISA 570 can be found and which deals with the going concern. The standard addresses a couple of factors that may be indications that a company can have problems with their continued operation. The problem is that ISA does not evaluate the events, which is more significant than others in the assessment, but it is up to the auditor to consider.The purpose of this paper is to describe the factors, which the auditor believes is more important than others in assessing the going concern and explain why it is so.
Affärsmöjligheter med Smarta Elnät : En studie som undersöker möjligheter och hinder i utvecklingen av det svenska elsystemet
Distributed, renewable generation-units and more efficient use of electric power,demands a developed electric grid. This grid is often referred to as the ?Smart Grid?.This future electric system rise expectations among actors in the existing electricmarket. International organizations share visions of opportunities for electricityconsumers and new actors, ready to enter the market. At the same time, electricutility companies may question the need for some of these upcoming changes, as theyare sometimes expected to lead the development.This paper therefore seeks to investigate the business opportunities related to SmartGrids.
Nationalbibliografin: en komparativ studie över musikområdet i Norges, Sveriges och Danmarks nationalbibliografier.
The national bibliography is an important tool in information retrieval. Bibliographies as lists of books have existed for centuries, but the national bibliography as we refer to it today, as a directory of the total national imprint, has only existed for about 50 years. The object of this thesis is to investigate music documents in Scandinavian national bibliographies. The method I have used for this investigation is a comparative study of the music departments in the national bibliographies in Norway, Sweden and Denmark. The investigation is performed by answering the following questions: How do Norway, Sweden and Denmark live up to IFLAs Guidelines and recommendations for the national bibliography? Can one discern any differences between the three countries in this area? The documents in focus are sheet music and phonograms.
Konkurser i små aktiebolag: En studie ur konkursförvaltares perspektiv med stöd av repertory grid -
De senaste åren visar statistik på att allt fler små företag går i konkurs. Bara under 2013 ökade siffran med fem procent gentemot tidigare år. Därför ämnar denna studie att belysa problematiken till varför konkurser uppstår samt vilka bakomliggande signaler företagen tar emot om en annalkande konkurs. Det är inte ovanligt att företag av olika anledningar bortser från signalerna de får om företagets ställning. Studiens huvudsyfte är att öka förståelsen för signaler vid företagskonkurser.För att besvara syftet har studien en kvalitativ metod med kvantitativa inslag.
Mellan kors och hakkors - Svåra val i en svår tid En studie av Biskop Alois Hudals förståelse av nationalsocialismen uttryckt i Die Grundlagen des Nationalsozialismus
Bishop Alois Hudal is a man who is often mentioned when the relationship between the Vatican and the national socialistic Germany of 1933-1945 is discussed. In these cases he is usually presented as a Nazi and sometimes even called ?the brown Bishop?. One of the contributing factors for this infamous title, perhaps the most contributing, is the Bishops book Die Grundlagen des Nationalsozialismus. National Socialism is a Weltanschauung with a certain set of doctrines that is hard, or rather impossible, to combine with any other Weltanschauung, whether it is a philosophical or a religious one.
Höjdmodellering med laserdata : Studie av Kärsön, Ekerö med fokus på upplösning, datalagring samt programvara
The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.
Vindkraft och elbilar på Öland år 2020 : Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?
The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed.The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.
Sydafrikansk film som national cinema : En jämförande analys av ett forskningsfält
The purpose of this essay is to study the film culture in South Africa in a national cinema-context, focusing on the relationship between anti-apartheid film from 1974-1994 and the film in South Africa today. By pitching the South Africa-specific works of Lucia Saks and Jacqueline Maingard against the over-arching debate on national cinema as formulated by, amongst others, Stephen Crofts and Andrew Higson, this study aims to find whether or not a specific South African national cinema have existed, and exists today, or not. The study finds that an underground culture of documentaries and short films made by and for the black population has been in place since the apartheid, and the distribution method on video and television is still being used to reach the black population today. By re-examining the concepts of both the national, and of national cinema to also include film on video and television, the study shows that South Africa has indeed a film culture that can be called a national cinema..
