A Brand New Manner : En studie om Design Thinking och dess existens i sta?rkandet av Sverige som varuma?rke

The purpose of this paper is to investigate the existence of the discipline Design Thinking in a project that aims to strengthen Sweden as a brand. The study will generate knowledge about Design Thinking, with the purpose to increase the understanding of how the discipline can be used as a strategic tool in the processes of strengthening Nation Branding. The authors have used a descriptive and qualitative approach where the Shanghai World Expo in 2010 was examined. The theoretical framework contains previous research in the field, data has been analysed in relation to Lockwood's ten principles of how an organization can become more design-minded and Anholt?s hexagon, which features the parameters that creates a country's Nation Branding.

Ett flervariabelt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

Analys av mätdata från nätstationer

Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.

Strategi för utvecklande av reglerbudata

This Master Thesis discusses the development of bids for regulation power with consideration of change of discharge. The study was initiated by Vattenfall PD and is a limited part of a substantial development project at the same division. The background of the project is the new demands from SvK, which among other things includes more detailed regulation bids. As from the 1st of November 2008, the regulation bids are supposed to be calculated regarding each specific regulation object, something that is defined by SvK. These new demands changes Vattenfall?s conditions and will increase the need for detailed knowledge about available regulation power and costs for regulation.In this study a strategy for regulation bids was developed.

Fåglar i urbana miljöer : kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

Faktorer som påverkade valet : En studie i blivande sjöingenjörers utbildningsval

Den svenska handelsflottan har de senaste åren varit utsatt för massiva utflaggningar vilket har lett till att många sjömän har fått gå i land eller sökt arbete under annan flagg. Trots problemen med utflaggning och en potentiell minskad arbetsmarknad har sjöingenjörsprogrammet de senaste åren inte haft några större problem att fylla sina utbildningsplatser. Framtiden är fortsatt oviss och konkurrensen från andra sjöfartsnationer ökar. Syftet med denna undersökning var att undersöka vilka bakomliggande attityder och förväntningar som gjorde att studenter år 2013 valde att börja studera på det fyra åriga sjöingenjörsprogrammet i Kalmar, samt att mäta inställningen till den allt mer krympande svenska handelsflottan. För att genomföra detta arbete användes en enkätundersökning där förstaårsstudenterna på det fyraåriga sjöingenjörsprogrammet utgjorde populationen.

Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion

Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

Kundlönsamhetsanalys som avbildande kalkyl och medskapande praktik: En fallstudie av Billerud

In recent years, customer profitability has become a focal point of academic discussions on business performance. However, researchers remain divided as to how evaluation of customers ought to be conducted, resulting in uncertainty of how accounting systems should be adapted to prevailing conditions. This paper aims to investigate the application of customer accounting techniques and the role they play in the organisational and commercial context in which they take place. In a case study of Billerud, a Swedish company providing materials and services for packaging solutions, the interplay between customer accounting techniques and customer relationship characteristics has been examined through the application of a theoretical framework developed by Lind and Strömsten. Particular emphasis has been put on deviations from the prescribed pattern of the framework.

Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål

This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper

This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.
