VillaService : En studie om hur planeringsarbete av en tjänstelansering lämpligen kan bedrivas
Service delivery acts like a process. This can enable the possibility of attracting attention towards the company who?s making use of this, furthermore generate several opportunities. However, it?s far from easy to deliver new services.
Föroreningar orsakade av stenar inblandade i barrmassaved
Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.
Hälsovägledares strategier och underliggandeantaganden vid motivationsarbete till viktnedgång : en intervjustudie om motivation
Syftet var att undersöka fyra hälsovägledares uppfattningar och strategier för att motivera individer till viktminskning. Avsikten var även att utreda vad de bygger sina uppfattningar och strategier på, samt att jämföra deras strategier med befintliga teorier om beteendeförändring såsom Motiverande samtal, Stages of change, Social learning theory och Health belief model. Teorierna valdes då de belyser hur en beteendeförändring kan gå till samt att de varit framgångsrika i tidigare forskning. Studien är kvalitativ och genomfördes med ostrukturerade intervjuer där respondenterna valdes genom ett bekvämlighetsurval. De fyra hälsovägledarna arbetade med att motivera individer till viktnedgång, alla hade utbildning inom hälsofrämjande arbete som varierade mellan en vecka till flera år.
Simuleringsprogram som verktyg vid projektering av solvärme
The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.
Animerad TV-vinjett : utsmyckning eller genre? En studie i animerad TV-vinjett
Today, the TV vignette is considered an embellishment to a TV program, despite its broad audiences and unique appearance. We wanted to find out if the television vignette has some common features and conventions but also find out how it relates to genre.We used a case study where we analyzed ten vignettes that we chose from certain criteria. We used a model based on image analysis that we modified to fit our needs. The main parts of each model consisted semiotics, imagery, dramaturgy and sound.We also made a couple of interviews with people who are active or used to work with vignettes. As a result we discovered that the television vignettes consist of certain conventions and that the vignette will not be considered as an independent genre, until the public has accepted it.
Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats
Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.
Grazemore DSS för att optimera utnyttjandet av bete i mjölkproduktionen :
The aim of the study was to investigate if the Grazemore Decision Support System (DSS) is able to provide a grazing management strategy that gives a high utilisation of grazed grass in milk production in the north of Scandinavia. To do this, a grazing experiment was planed and performed during the summer 2005. Simulations in the DSS were run to get a suggestion of how the cows should graze, grazing calendar 1. Deviations and updates during the season resulted in the simulated grazing calendar 2.
During the experiment, the actual milk yield was recorded twice weekly. The difference between actual and predicted milk yield by Grazemore DSS was analysed statistically with regression analysis and the mean square prediction error (MSPE) was estimated.
Monetära modellers prognosförmåga för den svenska kronans utveckling
Syftet med denna uppsats är att undersöka två monetära modellers prognosförmåga för den svenska kronan. Detta är den första studie som utvärderar prognoser på den svenska kronan under rörlig växelkurs. Modellerna som används är ?flexible price monetary model? samt ?sticky price monetary model?. Modellerna jämförs dels med en random walk-modell, men även mot varandra för att kunna påvisa eventuella skillnader modellerna emellan.

The participants have been inhabitants of Öland and returning visitors from the Kalmar region.
Omvårdnadsdokumentation : granskning av omvårdnadsjournaler inom psykiatrisk slutenvård
Background Swedish nurses are required by law to document nursing care. Studies have proved scarce in nursing documentation with regard to written language, the nursing process and the nurse´s caring perspective. Educating nurses in using the VIPS model have improved nursing documentation. Few studies have included nursing documentation of psychiatric care.Aim The aim of this study was to describe nursing documentation within psychiatric care of inpatient settings.Method A quantitative, retrospective descriptive research design was applied. A total of 60 nursing journals from a psychiatric department of six wards were studied.
Att våga tro på elevers förmågor : Lärares erfrenheter av att arbeta med elevinflytande i grundsärskolan
This study analyzes 66 Swedish actively managed mutual funds investing in the Swedish stock market during the period 2005-2014. The purpose is through pooled data regressions analyze the relationship between both the mutual fund?s annual fee and risk-adjusted return to the fund?s characteristics. The characteristics of the study are the size of the fund's assets, age, if the fund is bank managed or not, Tracking Error, and standard deviation of return.By using the performance measures of CAPM, Fama and French 3-factor model, and Carhart?s 4-factor model monthly risk-adjusted returns are created for all funds over the period.
Grazemore DSS för att prediktera beteskvalitet för mjölkkor :
The aim of this study was to examine if the predictions of the herbage quality in the software Grazemore Decision Support System (DSS) gives a reliable ground for milk production in the north of Scandinavia.
Pasture samples from one research farm (Umeå) and one organic farm (Nordingrå) was analysed on crude protein and organic matter digestibility. The results were statistically compared to the predicted values. Measured and predicted herbage mass was compared and a control if the predictions of milk production improved if the predicted input were replaced by the values from the analysis, was made.
The concentration of crude protein was underestimated by the model on both farms and the relationship between actual and predicted values was poor. Mean Prediction Error (MPE) was 24% and 31% respectively.
Framkomlighetsanalys med hjälp av en digital terrängmodell och kartdata
Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.
En metodutvärdering av pulsparametrar och beteenderegistrering i samband med utfodring av häst
Den parasympatiska nervbanan i det autonoma nervsystemet sänker hjärtfrekvensen (HR), medan den sympatiska nervbanan höjer HR. För att se vilken del som dominerar under en viss tid kan man mäta hjärtfrekvensvariation (HRV). En minskning i HRV visar på en minskad parasympatisk aktivitet och det sker när hästen är psykiskt frustrerad. När hästen är frustrerad under en kort tid går HR upp. HRV mäter tempo, tryck och längd mellan hjärtslagen.
Den vanligaste orsaken till stereotyper hos häst är kopplade till foder och utfodring och därför är det intressant att försöka mäta hur stor frustration hästen har vid olika utfodringssituationer.
Virtuella vävnadsobjekt för medicinska träningsapplikationer
This Master thesis discusses the development of a virtual human soft tissue object for use in exercise applications of various medical procedures.The soft tissue object to be developed shall look like, feel like and behave as living human tissue. It shall give the user a realistic feeling of weight, softness and roughness, and shall behave in a correct way for exercise purposes. The soft tissue model is to be used in a three dimensional stereo graphic environment with haptic feedback. A prototype for practicing the procedure of inserting a catheter is built. The prototype is used to evaluate the potential of the virtual environment for medical exercise applications, and to assess the realism and usability of the soft tissue object.
