Järnets förekomst i grundvattnet i isälvsavlagringar i Dalarna : Bakgrundshalter och rörmaterialets inverkan vid grundvattenprovtagning

A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

Bartóks violakonsert : studier av olika utgåvor

This master thesis is about the production of the record ?Brutus? with the band ?Trilobit?. Trilobit consists of the three musicians, myself, Stina Hellberg Agback on pedal harp, Simon Sva?rd on guitar and Karl Jansson on drums.During the production, I have analyzed different aspects of my own musicality and also the role of the pedal harp in jazz. I have found techniques that have simplified chromatic movements on the pedal harp, and also techniques that has developed the rhythmical aspect of my improvisation.I have also looked into my process in improvising and composing and developed new aspects, many thanks to the close collaboration with Simon Sva?rd..

Optimering av sampling quality-parametrar för Mental Ray

Fotorealistiska 3d-bilder används idag inom ett brett spektrum av branscher. Framställningen av denna typ av grafik kräver ofta väldigt mycket datorkraft. Vid rendering med renderingsmotorer som använder sig av raytracing algoritmer är aliasing ett medfött problem. Lösningen heter anti-aliasing som arbetar för att undvika aliasing artefakter som jagged edges eller Moiré-effekter med mera. En del av anti-aliasingprocessen är supersampling som ofta kräver mycket datorkraft.

Lönsamhetsanalys av tekniker för utökad elproduktion i kraftvärme : Med hänsyn till elprisets variationer

This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.

Kulturmaffians myggor och tigrar ? En litteratursociologisk studie av litteraturkritik och härskartekniker i en tidningsdebatt

The aim of this Master?s thesis is to examine how the literature criticism are in the Swedish media in the reception of the novel Mosquitoes and tigers from 2007 written by the Swedish author Maja Lundgren. A second aim is to examine how master suppression techniques have been used by the literature critics in the newspaper debate. This qualitative study is based upon a total of 52 articles and reviews from five big Swedish newspapers. The theoretical approach, literature criticism, mainly originates from the Swedish professor in Literature Science Tomas Forser and the literature scholar Gunnar Hansson.

New Generation Surface treatment for tools : A preliminary study

The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

Kundrelationer och Kundlönsamhetsbedömningar: En fallstudie inom telekom

This paper examines the customer relationships of a telecom operator and how their customer accounting is done. The aim is to use the framework developed by Lind & Strömsten (2006) to categorize customer relationships and see to what extent the framework predicts which type of customer accounting method is used for each customer relationship. A case study was made at Telenor Sverige AB where different customer relationships are identified and linked to the customer accounting techniques that are used for financial measurement of the customers. Findings include that all but one of the customer relationships described in the framework were recognized at Telenor and that most customer accounting techniques mentioned in the framework were in fact used and associated with different customer relationships. The results of the case study also highlight that some differences exist between the predictions of the framework and the observations at Telenor..

Automatisk indexering på webben - en studie av sökmotorn HotBot

The web has made an incredible amount of unorganized information available to anyone. There are search engines that help us structuring the information, but it is still difficult to find what you search for on the web. The purpose of this master's thesis is to investigate whether the already existing techniques for automatic indexing are suited for the new information retrieval context on the web and how the choice to support these techniques, or not, affects the search results. This is examined through a literature study on automatic indexing and other related concepts, such as information retrieval and information searching on the web in order to get a theoretical frame to the work and by an observation of the search engine HotBot to approach the purpose of the thesis. The observation is carried out by searching HotBot's database and investigating the search results in order to try to identify patterns that can reveal something about how HotBot's automatic indexing is done.

Flanksnitt som alternativ till linea-albasnitt vid ovariohysterektomi av tik :

In Sweden, the most common way to castrate a bitch is by midline approach. In this study, flank and midline approaches are compared in order to evaluate incision by the flank as an alternative technique for ovariohysterectomy in the bitch. The study was performed on straydogs in the central part of Thailand under field conditions. 32 bitches were included in the study. The castration technique was by flank and midline approach, alternating with every other bitch.

Data inom den sociala spelmarknaden

This is done by using literature reviewing,interviews with companies and analysis based on that information. The thesis initiallypresents important and central terms as well as different techniques.

Effektivisering av klimatskärm : a?tga?rdsfo?rslag fo?r bostadsfo?reningen Stocken

This study explores Environmental Storytelling techniques and whether these can beused in combination with each other to lead a player through a game scene in aspecific pattern, affect the player?s narrative and exploratory view and explorewhether Self-paced Exploration can be combined with these techniques.It is a qualitative study conducted by six gaming sessions with accompanyinginterviews in which six people get to play one of three versions of the same gamescene. The only differences between the scenes are the different guidance techniquesused. The informants' movement patterns are identified and interviews recorded byaudio, as well as screen recording. The results shows that Environmental Storytellingtechniques can very well be used to control the player's exploration patterns, bothnarratively and navigation purposes and Self-paced Exploration can be utilized to agreater efficiency in combination with these..

Bottenfaunan i Stensjöån och dess tillflöde Bokån : - en undersökning av tre lokaler

The purpose of this study has been to examine whether the bottom fauna of the stream Stensjöån, has been negatively influenced since the harvesting of peat began on the nearby peat moss Skäftesmyr or not. Comparison has been made with the results of index calculations from earlier examinations in the stream, two calculated indexes has been made, Danish fauna index and ASPT-index. The sampling was made with the kick sampling method, SS-EN 27 828. Three locations were chosen for the examination, one upstream from the peat moss, one just downstream from where the brook from the peat moss joins Stensjöån and a third location near the outlet of the stream to the lake Stensjön. The samples were sorted and the found animals identified to the taxonomic level required for the calculation of the two indexes.

Strukturerad- kontra beteendeintervju : Skillnad i mängd och kvalitet på den information som erhålls vid anställningsintervjuer

According to Barclay (2001), behavioral interviews yield higher quality information, than other interview techniques. This study focused on whether the quality and quantity of information differ between structured interview and behavioral interviewing. Two headhunters held 16 job interviews with the two techniques, 9 behavioral interviews and 7 structured interviews. Both headhunters and candidates have evaluated the interviews quantitatively. Initial and concluding interviews have, as well, been held with the headhunters.  No definitive answers were found in the quantitative analysis, but the qualitative results suggest that behavioral interviews give, because of the headhunters opinions, more and higher quality information.

Om du säger det så

This study explores the different effects on attitude and behaviour three frequently used advertising techniques have. The techniques compared are social influence and egoistic and altruistic benefit-appeals. The results showed that ads featuring social influence had statistically significant higher mean values regarding attitude towards the ad compared to both the other ads, and significantly higher mean values regarding brand attitude compared to the ad appealing to egoistic motivations. Though, all advertising effectiveness measures used in this study - that is, attitude and intention variables - indicated that social influence was more effective than the other advertising messages. Thus, in accord with earlier studies, it can be stated with confidence that social influence is an effective tool to use in marketing communications..

Könsroller och Härskartekniker i Twilight : (re)produktion av patriarkalgenusstrukturer genom smäktande kärlekshistoria?

This essay aims to describe and problematize gender roles and master suppression techniques in Stephenie Meyer?s Twilight Saga. This is done in order to enable me, in my future profession as a teacher, to start an emancipatory discussion in class where pupils can become conscious of different ways of reading the love story. I will use the following two research questions to fulfil the purpose: 1) investigate which gender roles that appears in the book?s main characters Bella and Edward and 2) which master suppression techniques that colours their relationship.To answer the questions gender theory and ideology-critics are used.
