Medias gestaltning av Uppsala Reggaefestival : ett problemfyllt evenemang?
Purpose/Aim: This essay seeks to describe in what way different newspapers framed Uppsala Reggaefestival, which is a music festival in Uppsala, Sweden. Not only the local press, but also the framing by national press will be analyzed. Furthermore, it seeks to discuss what causes different frames.Material/Method: The material consist of 96 articles from 4 different newspapers which are being analyzed through a quantitative content analysis method inspired by Melin and Lange, and their ideas of identifying the main message of a text. The media framing of Uppsala Reggaefestival are compared to another similar music festival in Sweden, Arvikafestivalen. By using theories about media framing and media logic the results can, if not explained, at least be discussed.Main results: The study shows that Uppsala Reggaefestival is framed in a way that is focused on the problems within the festival, for example drug abuse.
Controllern : Bönräknare eller företagspartner?
Denna studie behandlar controllern och dess roll. Då controllerrollen upplevs som väldigt diffus är syftet att förtydliga vad en controller är genom att använda begreppen bönräknare och företagspartner. Den teoretiska referensramen tar upp teorier från centrala författare inom området, bland annat Lindvall, Mattsson, Frenckner och Samuelson. Studien är en kvalitativ studie och utfördes på Saab AB i Arboga. Totalt åtta stycken djupintervjuer genomfördes med både controllers och icke-controllers för att på detta sätt kunna få en djupare förståelse för controllerrollen.
Värdering, Grafik och Logik : En kvantitativ studie av svensk nyhetsgrafik
News graphics as a part of journalism is something that?s constantly developing along with the news. That?s what we believed when we started this paper including its study. And we still believe the same, now that we?re done.News graphics itself is fairly common in Swedish newspapers, it can be seen every day in almost any major newspaper and is perfect for describing an event like the pollution of the sea over many years or just simply point out on a map where a city is located.This is one of the reasons to why we wrote this; another reason is that there?s almost nothing else written on the subject in northern Europe.
Inledning till spelutveckling för AndroidSpelutveckling för Android med Java och OpenGL ES
This thesis deals with the problems you face as a new game developer for the mobile platform Android when developing a 3D game and presents solutions to these problems. It also explores which optimizations should be made to increase performance and how well suited for game development the Android platform is. A simple 3D game for version 2.2 of Android was developed to examine this. The conclusion was that a good game structure for Android separates logic and rendering by running these separately in different threads. Solutions to rendering and updating of game logic were presented and optimizations were implemented for performance, although fewer optimizations were needed than was anticipated.
Metodutveckling av självskattningsformulär för prestationsmätning av flygledare innan skiftstart
This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.
Gestaltningsförslag till ny förskola på Zakrisdal
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.
En indirekt metod för adaptiv reglering av en helikopter
When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
Systemidentifiering och reglering av en luftningsbassäng på ett reningsverk
A wastewater treatment plant has the task to refine the wastewater from substances that should not be released into the environment. The decomposition process can, in a simple way, be described as follows: micro-organisms breathe oxygen and eat unwanted substances. The environment in which the micro-organism lives is known as sludge and the correct amount of oxygen available in the sludge is important for the decomposition to be effective. The oxygenation of the sludge alone stands for about 30% of the plant?s energy consumption.
Från produkt till prenumerationstjänst
The use of subscription services directed towards customers has become a common phenomenon in a vast number of different industries. We have noticed a clear trend of new businesses emerging solely offering subscriptions, and existing companies altering sales of their products to become parts of subscriptions. But research has not caught up with this trend yet, especially regarding why it occurs and how it affects existing businesses internally. The purpose of this study is to examine the driving forces for change and examine how existing businesses have to change parts of their business models to offer subscription services. The premise of this study has been Vargo & Luschs (2004) Service Dominant Logic with their foundational premises and Business Model Canvas by Osterwalder et.
EN NOT OCH TVÅ BOKSTÄVER - Diskursanalys kring användandet av tonnamnen H, B och Bb
Different ways of naming the two pitches between A and C exist in Sweden, Norway and Denmark. The Germanic tradition uses B and H, whereas the Anglo-Saxon tradition uses Bb and B. The aim of this study was to present a survey of the various opinions regarding these pitch names. The material consisted of different opinions about this matter from Swedish, Norwegian, and Danish websites. By means of discourse analysis the material was analysed in themes, which consisted of logic, tradition and communication.
Den mångsidiga controllern och dess samverkan med den operativa nivån
Uppsatsen syftar till att undersöka hur controllerns roll ser ut i ett stort tjänsteföretag samt hur denna samverkar med chefer på den operativa nivån. Vidare studeras även vilket inflytande controllern har på den operativa nivåns arbete. Studien bygger på intervjuer med controllern och ekonomidirektören på PayEx Solutions, ett företag som utvecklar elektroniska betalningslösningar. Därutöver har en enkätundersökning besvarats av chefer på den operativa nivån inom företaget.Controllerns uppgifter är inte väldefinierad i litteraturen och den har idag många olika arbetsuppgifter beroende på vilket företag som den är verksam i. De olika förväntningarna personer inom en organisation har på controllern påverkar också controllerns roll.

Controllern i svensk praktik ? En kvantitativ studie av en profession i förändring
Syfte: Att kartlägga samt analysera förändringar inom ekonomistyrningsområdet avseende controllerns roll, arbetsområde och styrmedel i svensk praktik Metod: En webb-baserad enkät skickades ut till 1000 controller i Sverige. Enkäten var utformad som en replikat från studien av Scapens et al (2002). Kvantitativa och statistiska metoder användes vid bearbetning av materialet Teoretiska perspektiv: Vi utgår ifrån att externa strukturella processer, s.k. förändringsdrivare, utvecklade av Lukka och Granlund (1998), som genom ekonomiska, normativa och tvingande tryck, samt efterliknelseprocesser, skapar homogeniserande praktiker i controllerns arbete. Slutsats:Några signifikanta skillnader mellan service- och industrisektorn i Sverige avseende controllerrollen, arbetsområdet och styrmedel kunde inte verifieras.
Service-Dominant logic i B2B kontext : Hur skapa mervärde på en eftermarknad
För att på ett effektivt sätt uppnå konkurrensfördelar på dagens marknad krävs det att företag finner nya strategier för att bli konkurrenskraftiga, en strategi är att verka på en eftermarknad. Företagskunder utgör en mindre marknad och beroendet mellan parterna är större (jämfört med privatkunder) påvisar detta att relationen är en viktig del i en B2B-miljö. Service-Dominant logic (S-D logic) beskriver hur ett paradigmskifte sker där kunden betraktas som värdefullt humankapital och företag vinner konkurrensfördelar genom långsiktiga relationer, värdeskapande tillsammans med kund och utbyte av kunskap genom interaktivt processarbete. Syftet med denna studie är att undersöka på vilka sätt företaget Komatsu Forest kan vinna konkurrensfördelar genom att implementera S-D logic. De strategier vi testar är front-line employee (FLE) ? personal med kundkontakt, butikslandskapet, varumärket och den interna kommunikationen.Studien baseras på kvantitativa studier med en kompletterande kvalitativ studie.
Metoder för lastprioritering i fjärrvärmecentraler
A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.
