Kakelugnar : en studie av Emil Petterssons kakelugnsmatriser
In recent centuries the Swedish Tiled Stove has varied in its design with an aesthetic evolutionary history that has not only followed the architectural and artistic ideals but also the taste in stove design. The heat source has varied depending on the regional traditions and where it was located within the country, but the inside of the construction was of a similar five channel system. The purpose of this paper is to study and compare the design of tile matrices made by Emil Petterson with other Swedish stoves. The following questions will be addressed:What characterized the production of a small scale tile stove workroom during the years 1900-50? Which main styles can be described as Emil Pettersson?s ideal while producing his matrices? And finally, is it possible to study the tile stove matrices as objects of historical and cultural significance, and what difficult methodological issues might occur in the doing of it? To answer these questions I will present the results of the documentation of Pettersson?s tile matrices with detailed historical categorizations and schedules. The conclusion shows that Pettersson as a stove builder and -producer was characterized by eclectic ideals and a design shape based on more liberal interpretations of contemporary trends.
Att skriva någon annans liv. Porträtteringen av historiska kvinnor i tre fiktiva biografier
The purpose of this essay is to analyze three works that are regarded as fictional biographies. In all three selected works the protagonists are historical Swedish women who are known for being a part of the cultural sphere of their time. Two of them are also recognized as important and somewhat pivotal characters in the struggle for women?s rights at the turn of the 19th century. The analyzed works, however, accentuate the women?s private life.
Oförglömliga karaktärer : En analys av karaktärsskildringar i fornnordiska myter och filmer om superhjältar
By conducting a text analysis this study analyzes possible similarities in the portrayal of story characters between historical Norse myths and contemporary film productions. The chosen historical texts are two stories from Norse mythology which render a myth about Thor and a giant named Hrunge as well as the myth Trymskvädet. The selected movies are two of the comic company Marvel?s productions about super heroes ? Thor and The Avengers. Different categories that this study compares are how the characters are defined by their possessions or artefacts, the actions and the choices which the characters make, and also how their relations, roles and origins are being portrayed.
Robotiserad produktionsanpassad magnetmontering för vågkraftverk
This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work. This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner. The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month. According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .
ADS och Matlab för optimering av pre-distortion av effektförstärkare
This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.
Modell och analysverktyg för beräkningav frekvensförlopp
The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.
Försvarsmakt i förändring : Svenska försvarsmakten 1988-2004
This essay is a case study about the Swedish Armed Forces during the years 1988-2004; when it transformed from a force constructed to meet an invasion, to an international force with the primary mission to help subdue conflicts around the world. The essay uses texts and documents to examine what happened between these years and to find out what drove that change.By asking the questions A) ?What happened between the years 1988-2004?? and B) ?What is the difference between the Armed Forces in 1988 and in 2004??, it is possible to also ask C)?Why did the Swedish Armed Forces change??.The essay is divided into three main parts; 1) a theory-part focused on three main theories of international relations: liberalism, realism, and constructivism, 2) a historical case study examining the evolvement of the Armed Forces during these years, and 3) a conclusions section that uses thethree theories of international relations to examine why this change happened.In examining the historical period and making conclusions about the differences between these years it was also necessary to construct a scale of military power, on which the historical case study is based..
Medeltid i samtid : Salvestaden en rekonstruktion i mellanlandet
The Middle Ages in contemporary time ? Salve City; a reconstruction in the Between Land is an essay dealing with the reconstruction of medieval Kalmar. The Salve City is a melting pot of such diverse fields as archaeology, pedagogies, reconstruction, historical tourism, regional development policy et cetera. Together, these parts form a space for research and mediation, business and pleasure, a place where commercialism and historical tourism can function alongside with history enthusiasts and entrepreneurs. Both pros and cons of the use of a reconstructed part of medieval Kalmar are debated..
Utveckla idag Bevara i morgon - Ett hot mot den historiska staden som destination
The aim of this thesis is to identify and analyse the antagonism between conservation and development which occurs in historical towns.The base of the study is theories in destination development and cultural heritage tourism in historical towns as well as the consequences expressed in these theories concerning conservation and development. The standpoint was that an empiric study needed to complement the theory. This filed study took place in Dubrovnik in Croatia. The thesis identifies the antagonism between conservation and development based on the theoretical research. Moreover the study adds a perspective to the research through the identification of further dimensions of this antagonism.
Det vi bevarar och brukar: om kulturarv i Svenska Offentliga Utredningar 1997-2004.
The purpose of this master?s thesis is to examine the use of the concept cultural heritage in Swedish governmental cultural policy. Ten official reports, reaching over a time period of seven years (1997-2004) are examined in the following way: What is cultural heritage? What functions/ values does the cultural heritage have? Whose heritage is a cultural heritage? With some simplification you can say that there are two different views on cultural heritage in the documents. The most common way to refer to cultural heritage is a category of chosen historical objects whose preservation is motivated by their function as sources of information and knowledge about the history and development of the Swedish society.
Ett levande klassrum : Undersökningar kring hur reenactment och historiska lekar kan implementeras i historieundervisning på högstadiet
In today?s history teaching in Sweden, role-play and historical re-enactment receive littleattention. Even though many students find history as a subject boring and irrelevant, verylittle is done to improve the mode of teaching. My theses is that this could be done bypresenting new ways of teaching and at the same time find a way to make more studentsinterested in history. The main aim is to investigate if there are ways to offer students anexperience of history by carrying out different interactive exercises with a touch of roleplayand historical recreation.
I tid och rum : en upplevelseanalys av Kärnan
In 2005 Gunhild Eriksdotter published Behind The Facades in which she analyses the ways of approaching historical buildings in archaeology. Eriksdotter emphasizes that the archaeology of buildings is in dire need of renewal videlicet the traditional outlook on buildings as two-dimensional objects need to change. She develops a method of analysing the spatial dimensions in a three-dimensional world. By fusing theories and methods in excavating archaeology and architecture, she is able to give us a new way of approaching buildings. Her method includes the analysing of a buildings material, spatiality and use.
Raymond Hains La France déchirée : En receptionshistorisk undersökning
This essay examines how the critical reception of French nouveaux réaliste-artist Raymond Hains 1961 exhibition La France déchirée has been articulated at two historically separate occasions.In her 2010 book Nouveau Réalisme, 1960?s France and the Neo-avant-garde, art historian Jill Carrick examines the fundamental impact the founder of nouveau réalisme ? French art critic and theorist Pierre Restany ? has had on the movement?s historical reception. According to Carrick Restanys writing established an interpretive framework that remained more or less intact for several decades. In addition to a closer analysis of the movement?s critical reception during the 1960s?, Carrick provides a set of new, alternative readings of a number of nouveaux réaliste artworks, which all originates from a position outside of Restanys interpretive framework.
De uteblivna möjligheterna? intressegruppers diskursiva hållning vid en stadsomvandling
Although being recognized as holding great cultural-historical significance by local officials, numerous parts of the functionalistic development along Friggagatan became demolished in 2008.This bachelor thesis have surveyed how the planning process proceeded through various municipal committees, and moreover, how different interest groups gathered around certain discursive attitudes. As a consequence of various paradigm shifts in society, e.g. that local government gradually are depending on private economic initiatives, there are to some extent a fear among politicians that cultural-historical demands can risk economic growth.Nevertheless, a building or a development are in fact bearing different value-perspectives, such as economic, functional and cultural-historical. Due to the fact that the heritage-sector has limited resources, in combination with sometimes vaguely and obsolete conservation documents, the sector have difficulties of responding common economic arguments, which leads that the real estate-owner gets total interpretative prerogative.However, despite a sometimes suspicious political attitude towards an improved conservation document, e.g. with continuously updates concerning a building?s technical and economic status, there are some political initiatives working towards it..
Modellering av rotationssystem
This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.
