Metoder för kartläggning och analys av nätförluster i lågspänningsnät

An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.

They shoot each other? : Våldet i en adaptationsstudie av Hungerspelen och Battle Royale

This thesis presents a qualitative, comparative study of the violence in the adaptations of Hunger Games (Tony Ross, 2012) and Battle Royale (Kinji Fukusaku, 2000). By analyzing the function of violence in a single scene in each of the movies, and comparing it to the literary original, the study aims to explore if there are any differences in the representation of the violence in the two media. The study also briefly discusses whether the violence has any function in bringing the story forward in both the literary sources and in the films and what the motivation for the violence is. "The study also includes a brief analysis of the narratives in relation to the monomyth established by Jospeh Campbell. Specifically, I discuss the similarities between Hunger Games and Battle Royale, which are two stories that have been created in two different cultural traditions, and whether or not we can say that the stories derive from this monomyth." The result concludes that the monomyth can be found in both stories, but that the scenes which is analyzed has to be put into the context and furhter story of the film to be of any relvance to the theory.

Automatisering av spraytorkningsprocess

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

Adaptiv temperaturreglering av bostadshus

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

The Consumer as Barrier vs. The Consumer as Partner

First objective: To bring forward managers? perceptions of the underserved consumers in emerging markets. Second objective: To reveal what implications managers? perceptions of underserved consumers in emerging markets provide for branding in these markets. Our study indicates that managers? perceptions are still lacking consumer insights within five elements (value, loyalty, purchasing power, consumers and consumption).

Lära för livet? : Svenskämnet ur ett elevperspektiv

The purpose of this study is to explore students? perceptions and experiences of the school-subject Swedish. Ten qualitative interviews with students in school year nine have been carried out and the results of these interviews constitute the basis of this study. The result shows that students have a straight-forward attitude towards Swedish as a school-subject. The students identify skills such as reading, writing and speaking, and work in school mainly concerns perfecting these skills. The students think of Swedish as a subject with a clear purpose and find it important and useful. The result also shows that the students want grading for the purpose of further motivation.

Sova med fienden - Orsaksförklaringar till uppkomsten av oheliga allianser i svenska kommuner

Over the last years there has been a considerable change in Swedish municipals. The number of municipals run by a rainbow coalition, a coalition made up of parties from different political blocks, has increased dramatically. Despite this clear pattern little research has tried to explain this increase. My thesis? aim is to try and clear the water around this subject by answering three questions about this type of coalitions.

Konsten att lyckas med förankring

The purpose of this thesis work is to formulate a model with methods that describe key success factors to get understanding and awareness in organizational change projects. We have used a project within the township of Gothenburg as a case and connected to this single project the purpose is to identify key success factors to get understanding and awareness among employees within the township of Gothenburg. We hope that our result will be useful in other large organizational change projects. Theoretic basis for our study have been models and methods, while our purpose have been to construct a model with suitable methods for anchoring. Theories about coaching and process management are examples of methods to get understanding and awareness among employees in change projects.

Ett nytt stadsbibliotek i Stockholm: En diskursanalys bakom visionen för ett nytt folkbibliotek

The purpose of this Master?s thesis is to examine and analyze the discourse concerning a new public library in Stockholm. The paper further discusses how this discourse corresponds with what is written about public libraries in a number of national and international documents. To do this I have utilized the discourse theory of Laclau and Mouffe. By using some of their instruments I have established the discourse around a number of keywords.

Gilla, kommentera, dela : Facebook som en kommunikationskanal för Eskilstuna kommun.

The local council of Eskilstuna has a lot of fans on their Facebook page, but not so many people that ask questions, likes, comments or share their posts. This is a bachelor-thesis on how to inspire dialogue and encourage the fans to be a part of Eskilstunas Facebook page.I have made guidelines for the council how to use Facebook as a way to reach out to those who live in Eskilstuna, based on results from literature studies, analysis of several other Facebook pages and interviews. I've also made examples of statuses for the Facebook page for one week, in May 2012.The result shows that the fans want's to read about their local environment. It is important to have a personal appeal. Post should be no longer than 400 character, if they are, the posts will be truncated, and hidden.

Inkrementell responsanalys : Vilka kunder bör väljas vid riktad marknadsföring?

If customers respond differently to a campaign, it is worthwhile to find those customers who respond most positively and direct the campaign towards them. This can be done by using so called incremental response analysis where respondents from a campaign are compared with respondents from a control group. Customers with the highest increased response from the campaign will be selected and thus may increase the company?s return. Incremental response analysis is applied to the mobile operator Tres historical data.

NASA på Nya äventyr i rymden : Populariseringen av den amerikanska visionen om rymden

The purpose of this thesis is to bring forward and discuss the American vision for space exploration found at NASA's homepage, how the vision is popularised and why. NASA's homepage is analyzed as popularized science and the theoretical perspective emanates from the field of popular science and especially the work of Johan Kärnfelt. The historical reference is made up by Howard E McCurdy and he's thoughts about space and the American imagination. The analysis is based on a number of documents that popularize the vision for space exploration and is intended for the public. These documents describe the future plan for NASA and US space exploration..
