Trafikverkets effektstyrningssystem - EFS 132 kV : Bidraget till minskade förluster
The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.
Den försvunna sången - En studie av en rekonstruktionsprocess
Title: The lost song. A study of a reconstruction process. I was asked by the daughter of the Swedish composer Svea Welander (1898 1985) for help to reconstruct a now lost song for voice and piano originally composed by her mother, where the melody of the song was used in the second movement of her first string quartett. The song was composed in 1955, words by Wilhelm Ekelund. My aim has been to describe the process of reconstructing the song.
Gestaltning av tillfälliga städer : en undersökning om egenskaper och gestaltningsprinciper
Designing temporary cities is a study of the design and physical planning of five temporary cities. The purpose was to discuss and note the important questions to be considered, when designing the outdoor environment in temporary cities to create as good an environment for the visitor as possible.
The five cities I have chosen are among the most famous ones in Scandinavia, and they represent different kinds of temporary cities. This was a deliberate choice to achieve diverse research material, and with that a broad view of what the planning stage generally looks like. Study of the cities has been done through interviews with the people responsible for the design and/or physical planning of each city.
Studentföreningen Spartakus i Linköping 1969-71 : en kvalitativ studie av dess politiska verksamhet och relationer
The aim of this thesis is to examine the politics and activities of the Social Democratic students´ association Spartakus. Their relationships and political and ideological differences towards the Swedish Social Democratic Party (SAP) and the remaining parts of the Social Democratic youth organisation (SSU) in Linköping during 1969-1971 are examined. To fulfil this aim I have studied relevant literature and interviewed people who were active in Spartakus, as well as people from SSU and SAP in the municipal during the period. I have also studied written material produced by the students´ association itself during the period. The theoretical frame of reference consists of Dahl´s theory on a democratic political order, and party theories like the mass party theory of Duverger, theories from Sjöblom, Panebianco, Lipset and Tingsten and also Gidlund&Möller´s theory about different kinds of party members.
Becketts papegojor. Språk, tal och berättande
The parrot is a common symbol, or even cliché, in Western literature, going all the way back fromancient Greece to the present date, and in many a genre. This study reads the oeuvre of the NobelPrize winner Samuel Beckett (1906-1989) as being closely related to these certain traditions andconnotations of for example religion, satire, and speaking nonsense, in his frequent use of parrotsand their symbolic potentials, in his writing. Furthermore, it is possible to distinguish a movementin Beckett?s use of parrots, from a more or less traditionally use, to one more philosophicallyprofound.Although the parrot graces us with its presence (or at least may be traced) in almost everywork written by Beckett, from the poem ?Whoroscope? (1930) to How It Is (1961), they are onlymentioned sparsely by his interpreters. Therefore, a brief history of the literary tradition of theparrot will be expounded.
Informationskompetens i Tyskland och Sverige : En jämförande studie av användarundervisningen vid två högskolebibliotek
This master?s thesis studies library teaching at two university libraries, Freie Universität Berlin in Germany and Södertörn University in Sweden. The aim of this paper is to study views on information literacy, how these views affect teaching practice, and how the teaching of information literacy is connected to, on the one hand, German and Swedish learning culture and, on the other, the local community of practice at the studied university libraries. The theories applied in this paper are learning culture and community of practice as developed in the works of Judith Ricken and Etienne Wenger. The methods that have been used are qualitative, semi-structured interviews that were conducted at both university libraries.It was observed that the teaching practices were highly connected to learning cultures.
En utredning av tekniken "mobile mapping" i kommunal verksamhet
This thesis work is intended to analyze whether the municipalities has a need for the new technology of mobile mapping.Mobile mapping consists of the technologies of laser scanning, photographing and positioning of streets and roads in city environment and in the countryside. When these technologies are operating together a georeferenced three-dimensional image model is created, which has specific coordinates that states its position on the surface of the earth. Thanks to the laser scanning process even measuring can be performed in this model.The municipal sector consists of many different departments which use visual spatial information. These departments are an interesting target group for this system. Specific departments within the municipal sector, which we considered were the most suitable, have been selected.
Kundvärden i förändring? : En studie av mobiloperatörer.
The objective of this study has been to examine which significant values are of importance in the telecom sector today, and in a continuing perspective yet to be. To ensure the factors of relevance in the study, we have identified three purposes: - Our first purpose is to clarify the eminent values in the competitive market of the mobile phone operators today, and the reason for its importance.- The second purpose is to understand the function of the brand regarding to value creation and loyalty in the sector of mobile phone operators.- The third purpose is to explore the potential approaches for mobile phone operators to increase value.In this study, our approach has been a qualitative methodology by conducting seven interviews with respondents related to the telecommunication sector.As a result of the process, we find the need to divide the concept of value into two dimensions, which we entitle organizational related values and customer related values. We have found the values related to the characteristics of the market in aspects of its infrastructural features but also in regards to the homogenous core service.Our findings in the empirical data with support to our theoretical frame of reference, is the current highly important organizational related value of constant high result quality (well-functional technological aspect), and the value enhancer by a low price; the strategy of bundling also results in higher value. This result in customer related values that perceives as safeness, availableness and convenience. The brands are a significant source of customer related values with identity value, image value and assuredness. A continued advancement in process quality and individualization will imply greater customer related values of closeness, freedom and flexibility. .
Skenbar arbetsbrist
In claims for unfair dismissal due to alleged redundancy, the burden of proof should be shared to enable an employee to have the cause of redundancy tried. In such a case, the employee should present evidence of an invalid cause ? such as personal reasons ? and the employer should account for the redundancy. With reference to their conflicting interests, the law favours the employer if the redundancy can be accounted for even if the employee maintains his or her position. This would have been reasonable practice if the employer?s evidence was subject to the same scrutiny as that of the employee but, as long as redundancy is considered a valid cause in itself, this is not the case.Redundancy does not come from nowhere, but it occurs when employers carry out their management decisions.
Intranät från ett användarperspektiv: En fallstudie om hur en grupp bibliotekarier upplever och använder sig av intranät i deras yrkesroll.
This is an investigation into the ways in which a group of librarians experience and make use of the intranet in their vocational role. The theoretical frame of reference consists of a model of how professionals seek information, which is based on a role-theory. As a method, I have applied a qualitative case-study. Using semi-structured qualitative interviews I have interviewed five librarians and the webmaster responsible for the intranet in their library. I have investigated how elements such as the age and vocational role of the librarians affect their use of the intranet.
Demokrati ur politikers och ungdomars perspektiv : - En diskursanalytisk studie om demokratiska förutsättningar i Norrköpings kommun
The democratic conditions in national states have change radically at the same time as the society has changed. Because of social and economic globalization processes, the states and government has lost power for the benefit of transnational and global institutions. That affects the democracy since the nation state earlier defined the domain of citizenship. At the same time, citizens? confidence towards political parties and politicians has gone down.
Förnuft och känsla : En studie av kokböckers visuella kommunikation under det tidiga 90-talet och sena 00-talet
The interest for food and cooking has probably never engaged the people of Sweden as much as it does today. Especially cookbooks are selling better than ever which has been a quite constant trend since the mid 90's. This study explores the connection between visual communication in Swedish cookbooks and the post-modern values which have influenced the market climate and the visual culture. I have used a theoretical framework as reference consisting of theories of semiotics, visual rhetoric, marketing communications and postmodernism. I have been studying six cookbooks, three from the late 00's and three from the early 90's, from the two separate angles of their graphic design and photographic material.
Diskonteringsräntan påverkar graden av miljöpolitiska styrmedel : En studie om koldioxidskattens påverkan på koldioxidutsläppen
This qualitative study involves the implementation of Lean and Kaizen methods in a Swedish service industry. Lean philosophy is based on a method to achieve more with less. In practical terms this means that the use of an organization's resources is improved. The origin of Lean is the Toyota Production System. Now, Kaizen methods give managers and employees a better more efficient system to reach their goals within the organization or company.
Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood
Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.
