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.
Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd
The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth.
Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.
På väg. En undersökning av en svensk stadsmotorväg
The purpose of this essay is to examine one of Sweden's oldest motorways in cityenvironment. The researched section is motorway E20 east of Gothenburg. Olskroksmotetin the west and Jonsered junction in the east, a distance of about 11 km. The mainquestion was, can maintenance of areas and objects related to the motorway give greatermeaning to a system that currently lacks historical connection?The survey was partly an archival study and partly a physical examination of themotorway and its appearance today.The road through Säveedalen from Gothenburg has a long history that begins with theriver and its valley as transport routes.
Kritiska faktorer vid implementering av ERP-system
Många företagsledningar har svårighet att värdera ERP-system och de förändringar som krävs i företaget för att införa ett ERP-system. Syftet med denna studie är att skapa en förståelse kring vilka kritiska faktorer som kan påverka implementering av ERP-system, samt hur organisationer arbetar med att hålla sitt ERP-system uppdaterat. Grundidén till studien kommer från Markus & Tanis (2000) som i en artikel beskriver den bristande forskning som finns inom ämnet ERP-system. Ytterligare en artikel som ligger till grund för studien beskriver en kanadensisk undersökning av Kumar, Maheshwari & Kumar (2003). För att kunna bidra med ytterligare forskning, samt tyda och förstå forskningsområdet är studien genomförd med ett hermeneutiskt ställningstagande av kvalitativ art.
Omkonstruktion av armled tillhörande Bracke Forest högläggare
One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.
Hur påverkar förtätningen stadens grönstruktur? :
Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter
distances, but not necessarily.
In the wake of urban density the greenstructures of the city is shattered.
The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.
August Strindbergs arkiv från privatarkiv till kulturarv: En studie i proveniensprincipens tillämpning och nationalistisk historietolkning.
In this thesis I examine the events that followed the death of August Strindberg and resulted in his private belongings becoming an important part of Swedens cultural heritage. My purpose has been twofold: firstly, to identify which aims were sought to be achieved when dealing with Strindberg's archives and his home and to relate these to a nationalistic interpretation of history, secondly, to relate this work to the then newly introduced archival principle, the Principle of provenance. I identified three different aims: firstly the economic aim must be seen in the light of an increasingly expanding publishing market. I argue that the author gained a new and important role in the general social debate a nationalistic one, an important point with regard to my following conclusions. Secondly, the aim to store and display the material in a museum is discussed in relation to different views of cultural history and the interpretation of history.
Movement patterns of Eurasian lynx (Lynx lynx) around their kills in southern Sweden
During the last ten- fifteen years the Eurasian lynx (Lynx lynx) population in southern Sweden has increased considerably. This area has a high density of both people and roads and have a higher roe deer (main prey of lynx) density than the rest of the country. Movement patterns such as how long animals utilize their kills and how far they travel from their kills between revisits is unknown for lynx in southern Sweden. The aim of this study was to examine how different factors affected the time lynx used their kills and the distances they travelled from the kill between revisits. The data was prepared and calculated using ArcGIS and the study is based on 98 ungulate kills and 12 lynx individuals.
Jämförelse mellan hundskolans och Svenska Brukshundklubbens kursdeltagare i Skaraborg :
The aim with the present study was to investigate whether there is a difference between the course participants who find their way to the dog-school respective the Swedish Working Dog Association. The study have focused on four issues; why the course participants have chosen the dog-school respectively the Swedish Working Dog Association, why the participants bought their dog, if the participants are satisfied with their dogs and if it is more likely that they turn to the dog-school?s than to the Swedish Working Dog Association with their first dog?
Course participants from two dog-schools and from two of the local clubs belonging to the Swedish Working Dog Association in Skaraborg, Sweden, answered a questionnaire. In total 85 answers were collected, including 60 from the course participants from Swedish Working Dog Associations and 25 from the dog school?s course.
Baskisk identitet - en studie av den baskiska nationalismens förändring.
The aim of this study is to analyze the change of Basque nationalism during the last ten years and discuss how the main nationalist party (PNV) tries to impose "we"- feelings and support for its cause. Theories of nationalism and national identity are used in the analysis.A textual analysis of PNV:s unofficial documents is discussed and compared with a discourse analysis of its official documents. Although the unofficial documents deal with similar view of basic political/territorial ambitions, language and identification, there are some differences in the latest documents regarding the view of who is defined as Basque and also to the detoriated relation to Spain. Although references are made to the regard that the Basque Country is for everyone, the persistence of emphasizing the uniqueness and myths of the Basque culture signals a different matter. The discourse analysis of the official documents supports this claim and although they contain an ambiguous relation to Spain it is clear that Basque nationalism has been radicalized.
Stubbtransporter - en jämförelse av tre olika transportsystem
In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.
Spela roll: filmregissör : Om tolkning, kommunikation och duktiga flickor
This text deals with the shooting of a movie comedy. The author of this text was script writer as well as director. The film was extremely dependent upon the interpretation of the role of the leading female character, but the director and the leading actress, in spite of their willingness to cooperate, were unable to understand each other, and no creative meeting ever occurred.The film dealt, in amused distance, with male and female strategies and shortcomings, but the lack of understanding between the director and the leading actress caused the subtleties of the text disappear, so that when the film was ready it was possible to interpret it in a way that partly opposed its intentions.From the director?s point of view different aspects of the situation are investigated: what could she /should she have done? What are the obstacles for a better understanding? Is ?understanding? dependant only upon that which is verbal? Should the director not only be a director but also a kind of therapist? What is professional and what is private? Could a director who wasn´t also the script writer have seen other solutions? And how does it affect you as a female director never to have role models, only a very clear idea of what you don?t want your professional role to look like.The director thought she was being constantly compromising, but finds out she was not, she had only a different, and in appearance, friendly but manipulative strategy in trying to reach her goal: that of enforcing and implementing her personal interpretation of the script. The role of director is also a role, and must be played.
Från känsla till handling : Empatins betydelse för frivilligas engagemang
Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.
En studie av elektronisk mobbning : Vilka kunskaper om och erfarenheter av elektronisk mobbning har flickor med språkstörning och autismspektra
The purpose of this study is to analyze the phenomenon of ?electronic bullying?, and furthermore to describe how this phenomenon is perceived by teenage girls with language disorders in combination with autism spectra. The conclusions and result from this study is derived from six in-depth interviews, thereof four being with girls with autism spectra diagnosis and all but one diagnosed with language disorder in addition (referred to as main respondents). The two reminding girls neither had language disorder nor autism spectra (referred to as comparing respondents). They were added to the study for the purpose of comparing their experiences and descriptions of those with language disorder and/or autism spectra diagnosis. For interpretation and analysis of study result, I have applied the method of phenomenology. The study?s main respondents had own experiences in the area of electronic bullying, albeit their level of knowledge of the subject were very limited and they had problems to interpret information given.
Jämställdhet åt skogen?! En studie som utreder anledningarna till att kvinnorna slutar som skogsinspektorer
The forest owner cooperative has observed difficulties with keeping women as forest advisers/ buyers. This is a problem because the organisation wish to have both men?s and women?s qualifications. The organisation?s purpose in their equality and multiplicity plan is to increase the knowledge and awareness of equality and multiplicity, increase the credibility to the members and customers, and to be well prepared for the future need of qualifications.
The purpose of this paper is to identify if there are any conditions that may limit female employees at this particular service.
