VIDA Vislanda har ett behov av att veta hur effektiv produktionen är på deras nya hyvleri. Därför är arbetets syfte att undersöka stopptidslängder samt bakomliggande orsaker till stoppen på företaget. Det ingår även i arbetet att lämna förslag på åtgärder som kan leda till förbättringar i verksamhetsgrad samt reduktion av stopptid.VIDA Vislanda vill veta vilken verkningsgrad, verklig löpmeter ut och verkligt stycketal ut för varje enskild dimension och längd. Resultatet presenteras efter detta önskemål men den totala verkningsgraden för hela mätperioden har också beräknats, till 52 %. Om VIDA åtgärdar de största återkommande stopporsakrna enligt våra förbättringsförslag kommer stopporsakerna att minska och således verkningsgraden att öka..

The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

This master thesis is looking into the stories on the internet forum www.resedagboken.se. The stories of Swedish teenaged exchange students in the U.S. are studied and the main purpose is to see both what they are writing about and the reason for why they are spending their time writing down their experiences in a public forum.Even though most of the teenagers here are writing with a specific audience in mind, all the stories are free to anyone to take part of and this causes a difficult position for the teenagers who often seem to forget the public point of view when they are telling about their personal lives.The study is divided into two parts. The first one looks into the content of the stories and the other one focuses on the storytellers and their reasons for writing. The teenagers are writing both a lot about their everyday lives in their new environment, but also a lot of things to keep in touch with what their friends and family in Sweden are doing.

Crowdfunding is a phenomenon that is subject to a great growth during the recent years, and the growth rate doesn't seem to stagnate. When new legislation named the JOBS Act in the U.S. becomes effective in late 2015, crowd equity will surely become a popular tool for financing businesses. Because crowdfunding great popularity is caused by the possibility to reach out to crowds through the internet, it is a global phenomenon, why it's relevant to examine current legislations in jurisdictions. This thesis covers an examination of Swedish laws of how they govern crowdfunding, and also suggestions on how the laws should be changed to more efficiently  correspond with the purposes of crowdfunding..

Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

Pairs trading is a relatively new trading strategy, the strategy has only been used during a couple of decades. A study made on the American stock market has shown that the strat-egy has generated a positive result. The purpose of this thesis is to investigate if pairs trad-ing has been able to create a positive result on the Swedish stock market during the time period of 1995-2004.The data required for this thesis was collected from Stockholm stock exchange and is ad-justed for splits and issues.The pairs trading strategy involves two stages ? identification of pairs and trading signals. The pairs were identified during a period of 12 months.

Syfte och frågeställningarSyftet med den här studien var att undersöka den aeroba fysiska aktivitetsnivån hos gymnasieungdomar på Bygg- och anläggningsprogrammet under skoldagar som innehöll teorilektioner, praktiska lektioner, idrottslektioner och raster. Frågan som ställdes var: Hur ser den fysiska aktivitetsnivån ut under teorilektioner, praktiska lektioner och lektioner i idrott och hälsa samt under raster hos gymnasieelever på Bygg- och anläggningsprogrammet.MetodI studien deltog 9 pojkar i åldern 16 år, längd 174-192cm och vikt 51-91kg. Den test som genomförts är 5 Minuters Pyramid Test (5MPT) och registrering av aerob fysisk belastning gjordes med hjärtfrekvensmätningar. 5MPT är ett skytteltest som är fem minuter långt, där försökspersonen tar sig fram och tillbaka mellan två stolpar och så snabbt som möjligt passerarfram och tillbaka över en vertikal pyramidformad trappramp (sträcka 5,5 meter). Antalet vändor, skattad ansträngning samt hjärtfrekvens (HF) registrerades.

Purpose: Our aim is to get an insight on how home care workers experience, handle and looks upon their work. We also want to form an opinion of how home care workers experience the relationship to the clients they meet.Questions: How does home care workers experience their daily work with their clients? Home care workers daily meet many different sorts of clients with different needs, how do they handle this? What kind of support does home care workers get in their work?Method: A qualitative design with semistructured interviews.Conclusion: The most central conclusion from all of our interviews were: that home care service workers has a very stressful and demanding occupation, that the work has a low status, that the personnel has a big responsibility for the wellbeing of other people and that they often find their work satisfying and fun. To have someone to talk to and exchange ideas with was also mentioned by the informants as a vital part of feeling support in their work. From the Antonovskys theory, a sense of coherence, and Goffmans views of the society, we also find that the larger part of our informants feel a high sense of coherence and that when they have to adjust to their different caretakers they play different roles..

The main purpose of this thesis is to contribute to the understanding of information needs of eight vocational studies teachers at the Handicraft Programme at a senior high school. I have analyzed the teachers? needs of information and the empirical material has been collected through interviews with eight vocational studies teachers.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

Some researchers claim that we are witnessing the advancement of becoming a network society, and in spite of the different problems associated with the network form of organization, many cities still choose to engage in different types of networks. On account of that the aim of the study is to examine which expectations Swedish member cities of the network Eurotowns might have, and if their actions in the initial period of engagement in Eurotowns mainly could be explained by ?Logic of Consequentiality? or ?Logic of Appropriateness?.A qualitative research method was used and a major part of the empirical material consists of the information given by the interviewees.Regarding the expectations Swedish member cities have on Eurotowns, the result showed that five main areas could be identified mutual resource exchange, activities, breadth, security and meeting place. The results also showed that the actions of Swedish member cities may vary between ?Logic of Consequentiality?, ?Logic of Appropriateness? or a combination of the both logics.Furthermore the study also provides empirical evidence supporting the previously theoretical criticism expressed regarding the central assumption that the strategic actions of an actor can be regarded as a direct consequence of the mutual resource dependency..

Glaciologer har under en längre tid observerat förändringar av glaciärer på Svalbard, att några minskar i storlek och att vissa växer. Avsmältning med ökade havsnivåer och potentiellt ändrad havscirkulation till följd är ett scenario som berör människor över hela värden. Dessa förändringar kan eventuellt förklaras genom att koppla de meteorologiska förhållandena i området till större cirkulationsförändringar.De meteorologiska förhållandena över Svalbard har simulerats med en regional klimatmodell, WRF (Weather Research Forecasting), för tre domäner med upplösningarna 24 km, 8 km och 2,7 km. Modellen har testats i två versioner, standard-WRF med förvalda processbeskrivningar och WRF med processbeskrivningar anpassade för polärt klimat och har drivits med ERA-Interim data, som är en återanalys av de globala väderförhållandena framtagen av ECMWF. Resultaten från WRF har verifierats mot observationer uppmätta av AWS-stationer (Automatic Weather Station).
