Key Performance Indicators och Kraljics matris : Verktyg för att realisera inköpsstrategier inom Saab
I takt med att inköp har fått en allt mer betydande roll inom företag krävs det också att strategier för inköp utformas på ett sätt som möjliggör att de kan efterlevas och följas upp, framförallt när det rör sig om koncernövergripande strategier som kräver samordning. I dagsläget är det inköpsrådet på Saab som styr över och samordnar projekt och initiativ som sker inom inköp. Inköpsrådet ansvarar även för framtagandet av inköpsstrategier och arbetet utifrån dessa för hela koncernen. En första klassificering av Saabs leverantörer utefter Kraljics matris genomfördes år 2010 och i samband med detta har ett ökat intresse påvisats för att på ett differentierat sätt mäta och följa upp leverantörer. Syftet med studien är därmed att se vilka Key Performance Indicators (KPI:er) som är tillämpliga i en indelning av leverantörer enligt Kraljics matris, det vill säga om olika KPI:er är fördelaktiga för att genomföra mätning och uppföljning av olika typer av leverantörer enligt Kraljics matris.En betydande slutsats med indelning av KPI:er enligt Kraljics matris är att studien ska påvisa vilka mätetal som är mest väsentliga att ha vid uppföljning av leverantörer kopplade till respektive kvadrant i Kraljics matris.
Svensk vindkraft
Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.
Datorspel = Lärande? : En kvalitativ studie angående gymnasieelevers attityder gällande datorspel som läromedel
The gaming market has become the fastest growing market for leisure and is one of the most popular forms of homeentertainment. This has generated a media debate about how people are affected by gaming and concernes how we are affected by the violence that may occur in games. Games proponents argues that gaming is the future of teaching and computer games are becoming a sustainable and popular instruction strategy. Some studies have long used computer games for educational purposes. By interviewing high school students in focus groups as qualitative research, I studied their attitudes towards computer games as a learning tool.
Pojkars och flickors värderande uttryck i narrativa texter. : En studie av elevtexter i årskurs nio.
This study is based on my work as a teacher of Swedish language and literature to upper secondary school students, and my interest in developing the teaching of literature by using both new criticism theories and theories of literary perception focusing on reader response. The purpose of the study is to examine the learning process in trying to develop literary competence and to find out how to describe the competence shown by the students. My starting-point is a discussion about literary competence and the theory and model of literary competence by Örjan Torell. In examining literary competence, by how students use their constitutional competence as well as performance and literary transfer competences, Torell´s model shows the possibility and the need for both knowledge of literature and personal reception by focusing on the dialogue between author and reader.The method is qualitative and the empirics are material collected in one senior high school class in the Social Science programme during their second and third year. The material contains written reading logs, written answers to tasks and transcribed recordings of discussions of literature.The analysis shows a variety among the literary competence shown and developed by the students and points to the complexity of understanding the concept of literary competence.

Kinematisk och dynamisk modellering av den haptiska enheten TAU i sex frihetsgrader
The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.
It?s a Guru Thing - Vlog Popularity in the Beauty Community : En kvantitativ samt kvalitativ studie om vad det a?r i sko?nhetsvideor som genererar visningar.
The overall purpose of this essay is to come to a deeper understanding about videos in the Youtube beauty community by using a mixture of qualitative and quantitative methods. By answering the main questions of the essay which are; What quantitatively measurable components are there in the videos that can be seen as contributing factors leading to the fact that some generate more views that others?; Is there a set mold for success containing certain aspects that a video must have to stand out?; What correlations can be found between the two categories of analysis and how do these potential correlations affect the popularity of the video? and What effects do specific components on the level of popularity of the video?, we?ve been able to distinguish differences as well as similarities on both qualitative and quantitative levels. We have also seen that using the two methods together have enabled us to reach more profound results. The main result that we have found on a quantitative level is that there are obvious correlations between a high level of popularity and a good visual quality.

En kartläggning och utvärdering av vårdkvalitet inom den rättspsykiatriska öpenvården i Malmö: utifrån ett patientperspektiv
The aim of this study was to map out the quality of the treatment in the forensic outpatient care unity in Malmoe from a patient point of view. This target group, seriously mentally disordered law-offenders, has been neglected in the scientific research. This investigation will hopefully contribute to a positive change in this subject. To achieve a good understanding of this field a methodological triangulation was conducted which included an observational study, a pilotstudy and semistructured interviews. 14 patients and 10 staff members were interviewed.
Gymnasiebibliotekariens yrkesroll En fenomenografisk undersökning.
Although school librarians have an important role to play in high schools helping teachers and students during their education, Swedish school librarians are often considered to end up left out by teachers and head principals due to school librarians vague and unclear professional role in the school. The aim of this thesis is to attempt to study school librarians own apprehensions of their particular professional role in a high school context, and how their professional role is believed to be apprehended by teachers and head principals. The results are based on interviews made with eight school librarians working in different high school libraries in Gothenburg during April 2002. By using phenomenographic method various existing apprehensions of the specific phenomena that the professional role of the school librarian constitutes of are made clear. The aim of the method is not to study what the profession constitutes of, but rather how it is apprehended by the school librarians themselves.
Utvärdering av ett IR-system i en informationssökningsprocess ett holistiskt perspektiv
The research objective of this thesis was to conduct a holistic evaluation of an operational information system. By holistic evaluation we mean that an equal focus was placed on both the system system perspective and its users user perspective, in the actual environment where the system and its users function contextuality. In addition, the methodological objective of the study was to test a new research approach in a real life setting. The participants of the study were twenty newspaper journalists employed at Göteborgs-Posten GP. The information system NewsLink is a manually indexed full-text database containing all articles published in GP since 1994.
There is no there, there : om platslöshet i fysisk planering
The vizualisation and creating of places is an essential part of physical planning. The notion of places as placeless, is likewise of importance for the creating of places. Some tendencies concerning architecture like modernism, as well as constructions whome don´t fit in their landscape, have contributed to the benaming and experience of places as placeless. Phenomenon as globalization and post-industrialism have in some cases conduced to the withering of the sense of place. With starting-point in litteraturestudies, observations of places and interviews, this is a lucubration concerning the means of placelessness in physical planning.

Employer branding : En studie i hur Uppsala Universitet bygger sitt arbetsgivarvarumärke
Purpose: Our purpose is to achieve a higher understanding of which factors University of Uppsala is using to attract and keep their existing workers.Theory: We have worked with Barrow & Mosley's the employer brand mix, this modelexplains 12 important factors that exists within the employer branding process. External reputation, internal communication, the board, values and corporate social responsibility, internalmeasuring systems, service support, work environment, rewards and acknowledgements, learningand development, performance estimation, team management and recruitment and introduction.Method: To achieve an understanding of our subject we have chosen to work with a qualitativemethod. This type of method is more considerate of the interviewed person?s way of seeingthings and also accounts for how the person answers. To answer our problem statement we haveconducted a case study on University of Uppsala where we used semi structured interviewsbecause we wanted to limit the risk of leading questions.Empirical findings: University of Uppsala were used as material for our empirical discussionContext: The main reasons that workers is attracted to and are staying at the university dependson the external status they achieve when working there, this combined with that the workers getsto be a part of the university's brand.
Modellbaserad temperaturregleringav partikelfiltrets regenereringsprocess
Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.
