Banbrytande formgivning i Sveriges textilindustri En studie om Astrid Sampes m?nsterproduktion
The main focus of this study are the textile prints created by Astrid Sampe (1909-2002). Her fabrics can tell us more about her than a biography ever could. They can reveal how we experience patterns, why we are attracted to them and how our preferences can evolve over time. This study examines four different patterns, and the thesis aims to define Sampe and her textile prints using three different theories and a formal aesthetic analysis. Modernistic and postmodernism theories are relevant when explaining the period where the fabrics were created and how Sampe's ideas were conceived during her lifetime.
En analys av steg och konsekvenser vid införande av MVC

A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.
Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.
?Tolkien himself would be proud? - En studie av fansens deltagande i expanderanderingen av en fiktiv värld
This essay examines fans contributions in a transmedia culture. I examine how fans relate and use the fictional worlds in the creations of their own films. The study focusing on the use of graphical elements and character design in some fan films. The examination is done by using two intertextual theories. One of the theory is Lubomir Dolezel theory on transfictional relationships and the other one is Gérad Genette theory on the realtion in transtextuality.
Enhetschefer och undersköterskors perspektiv på rapportering enligt lex Sarah inom kommunal äldreomsorg
The aim of this study was to examine the experience, knowledge and attitude to mandatory reports of mistreatments amongst first line managers and assistance nurses in municipal elderly care. The following questions were at the center of the analysis: how do the different professional groups view having to report their own organization? How can various factors affect the mandatory reporting of mistreatments? What knowledge do the different professional groups have of mistreatments and mandatory reporting? A qualitative research method was used to examine these questions in the form of semi structured interviews and a small document study. The interviews were carried out with assistance nurses and first line manages in elder care, we interviewed four respondents from both professional groups. The interviews were then transcribed and coded with help of a content analysis.
Ljuddesign för rumsmetaforbaserade talgränssnitt
In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.
HPM som luftvärnsvapen mot kryssningsmissiler, en möjlighet?
I denna uppsats undersöks huruvida HPM (High Power Microwaves) kan användas som enverkansform i framtida luftvärnssystem för att bekämpa kryssningsmissiler. Studien undersökervilket hot kryssningsmissiler kan utgöra, hur de är konstruerade och hur HPM kan påverka dem.Uppsatsen redogör för hur det nya luftvärnskonceptet är uppbyggt och vilka krav på förmågor somställs på framtida luftvärnssystem. Den undersöker även hur ett HPM-system är uppbyggt ochvilken verkan det kan ha på elektriska system i en kryssningsmissil. Vidare diskuteras vilkeneffekt tre olika HPM-system kan ha mot kryssningsmissiler kopplat till de krav som ställs iluftvärnskonceptet.Huvudslutsatsen indikerar att HPM-system kan ha verkan mot kryssningsmissiler. HPM-systemkan nyttjas främst i scenarier där det ställs höga krav på eldhastigheten mot kryssningsmissiler påkorta avstånd.
Cykelparkeringsplatser : Grundläggande principer för planering, lokalisering och utformning
This bachelor thesis is about illustrating the fundamental principles for planning, locatingand designing bicycle parking spaces. The study aims to give an understanding of theneed and demand for bicycle parking spaces today, as well as to determine how these canbe met according to different theories. The study also aims to investigate the issue withincorrectly parked bicycles, which occurs frequently in the cityscape and therefore createsan obstacle in street spaces.An observational study on the new bicycle lots along Götgatan was conducted in orderto analyze how the theories of bicycle parking spaces are applied in practice. Cyclistswere then interviewed in order to obtain a deeper understanding of the cyclists? revealedpreferences.
Social Demokrati : Sociala medier, Politiker och Demokrati
The aim was to explore how the first page of a student newspaper has been changed over time since it was founded in the 1960´s.This thesis explores how the front page of the student newspaper Lösnummer has been changed since it was founded in 1966. It concerns the location and frequency of elements and it is based on theories of layout, the first page and visual communicationIn addition, the thesis develops a new kind of method for determining the location of elements on the type area. The method is based on the hexadecimal number system. It is formed as a grid which is placed on the first page to determine the location of the elements.It concludes that the frequency of elements had its peak during the 1970´s and has ever since decreased gradually. Image placement has gone from being scattered all over the front page to be centered and increase in size. .
Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning
Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..
Standardisering av förpackningar på HABO AB
This thesis project has been written and accomplished in cooperation with HABO AB. The objective of the project was to develop a standard stated packaging system. The background to this is that HABO is not pleased with the system currently in use. The system which HABO is currently using consists of to many sizes. The largest benefit of a standard stated system is that it becomes much easier to organize the packaging with the aid of a computer program.
Kulturen bakom kulturen - En komparativ studie av kultursynens inverkan på tyska och svenska kulturpolitiska strukturer
This thesis aims to develop a theory in the under researched field of international comparative cultural policy studies. lt does so by combining theories from the fields of political scienceand cultural studies, researching how and to what extent the concepts of culture of different states have an impact on the way cultural policies are constructed.The thesis uses this theoretical development in order to research a specific problem, namely the perceived possibility that Swedish and German cultural structures are slowly converging. Two recent official policy documents from each country are the objects of study. Through comparative idea analysis and with Michiel S. D Vries theories on decentralization, the thesis explains the convergence between the countries by differing cultural views between them.
The Rationale Behind Capital Structure Decisions: Does Theory Explain Practice?
The purpose of this thesis is to through the analysis of interviews with finance professionals in listed companies answer the question on what lies behind capital structure decisions, and to see how well the prevailing theories fit the answers. This article is an explorative and descriptive hypothesis creating study. We have used a qualitative method to analyse practice through theory. We have conducted telephone interviews with CFO:s and financial executives in Swedish listed companies on how they reason when they make capital structure decisions. We have then thoroughly reviewed the theory and empirical tests of the theories.
