?Horan, knarkaren och fettots fortsättning?? : En queerfeministisk analys av de normbrytande personligheterna i romanen Eld
Engelfors Trilogy is a three-part fantasy novel consisting of Circle, Fire and The key, written by Mats Strandberg and Sara Bergmark Elfgrens. Circle was nominated for the August Prize award 2011, which is a literary prize awarded each year. The book has also been translated into 25 different languages. Fire came out in August 2013 and is the part of the novel that I will concentrate on in these theses. What I will do in this paper is a queer feminist analysis of the novel's main characters in the book Fire.
I stundens hetta : En kvalitativ textanalys om gestaltningar av krisarbetare i samband med skogsbranden i Va?stmanland sommaren 2014
This qualitative study examines how emergency people are framed in Swedish evening-, and local newspapers during the forest fire in Va?stmanland, Sweden 2014. The study also includes if there is any difference between the framing due to the location of the newspaper. The study is based on qualitative text analysis. The theoretical basis is representation, framing theory, media image, media logic and a few conceptions from crisis communication theory.
CFD simulering av en fyrtakts Otto motorcykel motor
This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.
VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor
Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

Value stream mapping i praktiken : En fallstudie på Light My Fire
Titel: Value stream mapping in practice ? A case study at Light MyFireAuthors: David Rydman and Tomas ÖnnemarMentor: Veronica Ülgen SvenssonExaminer: Åsa GustafssonBackground: Companies push their prices in today's markets to be competitive, which means that companies need to find ways to reduce costs while maintaining profits. (Cudney, 2009) According to Bergman and Klefsjö 2007, the basic rule of quality improvement says "there is always a way to achieve higher quality at a lower cost". One way is to improve a company's processes to get a more efficient flow and improvements that may cut costs. (Bergman & Klefsjö, 2007) Why it's important to look at the processes are that they often contain waste that can be eliminated.
Reglerstrategi för fria ventiler : ? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar
As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.
Akademiska söktjänster: En jämförande studie av Google Scholar, MEDLINE och Web of Science
The purpose of this paper is to compare the three search engines Web of Science, Google Scholar and MEDLINE in regards of recovery efficiency and the overlap of relevant documents when it comes to information searching for academic purposes. Furthermore, it raises the question whether freely available search engines and licensed search engines are interchangeable with each other. The empirical data in this study were collected through searches conducted in the three search engines Web of Science, Google Scholar and MEDLINE. Twenty search queries were used and the first twenty retrieved documents for each query were examined for relevance using previously designed criteria. The documents were scored by a binary relevancy scale and thereafter a precision value for each search engine was calculated.
Trycksättning och dimensionering av brandhiss för berganläggning
This thesis deals with the design of a combinated rescue-, personal-, and firefighting elevator for a nuclear waste storage facility to be constructed by the client SKB, Svensk Kärnbränslehantering AB. SKB:s mission is to dispose of all nuclear waste from all swedish nuclear power plants. The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.
Beslutsmodell för inköp och lagerhållning av motorer i ett produktionssystem : En fallstudie på Sandvik
AbstractIt is important to choose which spare parts to keep in stock. With the right spareparts in stock the costs for inventory and production loss will decrease. Cavalieri et al. (2008) highlights that the balance between inventory cost and production loss is underestimated. It affects the company and must be considered before decision on purchase.The problem with spare engines is that they are all more or less critical for the production. That can be a reason for why no previous research targeting engines and classification of with engine should be kept in stock has been found.
Effekter av olika skiftformer : En studie om effekter av olika skiftformer inom räddningstjänsten
Bakgrund: Uppsatsen tar upp problematiken kring att organisera arbetstid inom räddningstjänst. Grundförutsättningarna är att räddningstjänst är en High Reliability Organisation (HRO) och att det påverkar organisationen. I och med New Public Management (NPM) framfart och den ekonomiska situationen i världen har räddningstjänsten fått ett ökat krav på kostnadsbesparingar och resursutnyttjande. Då personalkostnader står för en stor del av räddningstjänstens kostnader kan förändringar av brandmännens arbetstid och skiftgång vara ett logiskt steg, något som skett i Greater Manchester Fire and Rescue Service (GMFRS).Syfte: Syftet med uppsatsen är ett ge ett teoretiskt bidrag till hur NPM influerade reformer påverkar en HRO. För att göra detta frågar vi oss vad de olika skiftformerna får för konsekvenser för de anställda och organisationen.Metod: Uppsatsen har en kvalitativ forskningsansats vid studerandet av fallorganisationen Greater Manchester Fire and Rescue Service och Storstockholms Brandförsvar.
Mortalitet och skottskjutningsförmåga hos ek (Quercus robur) efter brand :
In this study I analysed how burning affects sprouting ability and survival of oak (Quercus robur) during the first season after a burn in southern Sweden. The study
consisted of two separate field tests; in the first, two 300 m2- plots in western oak
dominated forest were burned to analyze the fire behavior and the immediate mortality of oak and beech seedlings defined as individuals (> 20cm of height). At the end of the season almost 50% of the oak seedlings had resprouted while the beech seedlings had 100% mortality. An attempt to investigate the effect of the burn of artificially sown acorns was totally ruined by wild boar grouting before any conclusive results could be seen.
In the second test the resprouting ability of oaks of varying diameters (average BHD 7-9 cm, range 2-42 cm) was examined one season after a prescribed burn in southeastern Sweden.
VÄRDEFLÖDESANALYS AV PW1000G 30k TEC
The thesis work has been carried out at Volvo Aero Corporation (VAC) in Trollhättan. VAC has entered a partnership as developing and producing partner with engine manufacturer Pratt & Whitney and is currently at the starting phase of producing the turbine rear frame (TEC) to the engine PW1000.The purpose of this study was to create a report on process level that describes the conditions and the potential with PW1000 TEC to reach the product cost calculation taking into account lead times and describe alternative method solutions.The report describes a comparison between the present flow (2012), a flow based on product cost calculation (2016) and a potential flow (2016). The work has mainly been based on acquiring the knowledge and information available to inspect the present flow; this has been done by workshop observations, meetings and gathering of the information that is available on the work site for the PW1000 TEC.The information obtained has been merged into an Excel document, called Roadmap. It serves as a roadmap with current situation as the start and the potential flow for 2016 as the goal. With the roadmap as a tool, assumptions have been taken considering the flow and how it will change, where processes have been eliminated, reduced or marked as a problem..
E-böcker och bibliotek. En diskussion kring den digitala beståndsutvecklingens möte med en gryende e-boksmarknad
In Scandinavia the general idea of the Bronze Age society is that it was organised as chiefdoms. The model for what they looked like is taken from the anthropological studies of the Polynesian chiefdoms. The aim of my study is to investigate a Scandinavian Bronze Age feature, known as cairns mainly containing fire-cracked stone. This is compared with how people in different Polynesian chiefdoms, looked at similar remain. This is done to get a background for new ways of interpretation of such remains.
