Solenergi på Kvarnholmen
In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.
Implementation av ett interface till Emotiv Epoc
The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.
Motivationsfaktorer : - Vad påverkar motivationsnivån hos telefonförsäljare?
Through an examination on a Telemarketing company this paper aim to investigate which relations there is between the level of motivation and performance and how these are related to the factors that are included in Herzbergs two-factor-theory.In this essay we have been using a questionnaire and interview. We have also been able to collect statistics on employees from the Telemarketing company we examine. On the basis of these data we have analyzed which relations there is.The examination shows on relations who mean that the factors Performance and Acknowledgement are the ones that affect the motivation the most, and therefore the level of Performance. The rest of the Motivation factors don?t show any clear relations.
Itrimdeltagares upplevelse av sin viktminskning
En del personer med övervikt vill gå ner i vikt, men det kan vara svårt att lyckas. Studiens syfte var att ta reda på deltagares upplevelse av sin viktminskning på Itrim. En kvalitativ studie med 9 personer, varav 7 kvinnor som deltagit i Itrims viktminskningsprogram intervjuades och datamaterialet analyserades genom meningskoncentrering. Enligt motivationsteorin Self-Determination Theory (SDT) så ökar sannolikheten för att beteendeförändringar blir bestående om de är autonoma och motivationen intern. Resultatet visade att deltagarna upplevde sin viktminskning som positiv och att Itrims koncept fungerar bra.
Tetratermmodellering och regressionsanalyser mellan topografi, tetraterm och tillväxt hos sitkagran och lärk : en studie i norra Island
This study was made in an attempt to give the forest research centre Mógilsá a producedtetratherm map and a better understanding of how topography and temperature influencethe growth of two tree species. The digital tetratherm map model, covering the northernpart of Iceland, was developed to investigate the correlation between tetratherm and thegrowth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms theusefulness of digital terrain models in providing data for a lot of different factors and forthe tetratherm model. Hopefully will this tetratherm map be used in future studies.Secondly, investigations were made correlating the growth of the two species againsttopographic factors representing height above sea level, distance to the sea, slope andtopex. Thirdly, investigations were made comparing the aspect and the ground shape tothe growth.The growth rate of Larix had strong significant correlations to the tetratherm and thedistance to the sea- factors.
Mätning av rälsprofil med STRIX
STRIX är Banverkets mest moderna mätvagn. Med denna utförs bland annat mätningar av rälsprofilen med ett optiskt system som är monterat under vagnen. I detta examensarbete jämförs mätningar från STRIX och mätningar från det handhållna systemet MiniProf. Målet med jämförelsen är att visa om nya metoder som har utvecklats under examensarbetet leder till förbättringar av mätningar utförda med STRIX. En tänkbar förbättring av de mätningar som utförs med STRIX är att byta den referenspunkt som används vid matchning mot en referensprofil.
Uttalssvårigheter i svenska som andraspråk hos personer med thailändsks som primärspråk
The intention of this study is to compare difficulties of Swedish pronunciation of five second-language learners with Thai as mother tongue. Thereafter make a comparison with previous research in pronunciation difficulties in people with the same primary language to see if the deviations are similar. I used both recorded material/recordings which I analyzed as well as experiences from pronunciation training that I observed at SFI. The pronunciation difficulties were documented and entered in tables. The recordings consist of 25 Swedish words and a text performed by five informants. In my study, you can distinguish a pattern in my five informants pronunciation difficulties complying with Bannert informants who also have Thai as primary language.
Änglar och sorg : Angels and mourning
What psychologial processes are activated in experiencing mourning after a loss of a belovedperson? How is death described in other authors? novels and short stories compared to mine?This essay aims at analysing my two short stories The follower and The price for love fromdifferent aspects. I discuss the psychological realism and the spirituality using the method ofclose reading, interpreting and applying ideas of texts from other authors in my short stories.Death is a central phenomenon in both of my texts. Therefore I discuss death frompsychological and philosophical aspects in this essay. To get a philosophical frame of death Iturn to Jacques Derrida, Emmanuel Levinas and Martin Heidegger.
Vart jag mig i världen vänder : En studie om konsumenters förhållande till researrangörers CSR
Purpose: To examine how a tour operator works to implement sustainability in the development of the business, as well as what significance it has to consumers in selecting a tour operator. Furthermore, the purpose is to provide recommendations on how tour operators should work to communicate their commitments.Methodology: The research strategy applied is a case study which follows an abductive approach. Qualitative and quantitative methods were applied to complement each other. A semi-structured interview with a tour operator and a consumer survey constitute the empirical foundation.Conclusion: The conclusion of the study is that consumers show a positive attitude towards CSR, but do not see it as a determinant when choosing a tour operator. Thus, CSR does not constitute a competitive advantage against competitors.
The Capital Structure Puzzle of SME's - Evidence from the Swedish Security Industry
The purpose of this thesis is to ascertain the main determinable factors of Swedish SMEs capital structure decisions and to investigate whether existing capital structure theories are applicable on Swedish SME financing. We have used panel data to run regressions of various capital structure determinants on three measures of capital structure; short- term debt, long-term debt and total debt. We found that growth opportunities, profitability and age are the most important capitalstructures determinants for our sample. Firm size shows a small explanatory result but the effective tax rate and the asset tangibility do not seem to explain the capital structure at all. Thematurity matching principle is considered significant..

Fredningseffekter och rekryteringsproblem hos abborre (Perca fluviatilis) i Stockholms skärgård
Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..
Mekaniserad plantering med Eco-Planter i södra Sverige :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting.
Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester.
The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive.
The biological output, e.g. planting result and survival rate, seems to be quite good.
Att genom design effektivisera räddningsinsatsen för motorcyklister i trafikolycka
What if the emergency response directly knew exactly where to go and what to do if a road accident occured? During the last ten years the number of motorcyclists in Sweden has doubled. Every year, more than 300 riders are seriously injured and over 40 die in road accidents. Being found in time is critical to increase the chance of survival. The goal of this project is to use design methods to find a solution that enables a fast and adequate emergency response for motorcyclists and other unprotected road users..
Befolkningstillväxtens mosaik i Umeå kommun
The purpose of this thesis is to present and analyze population developments within Umeå municipality during the period 1992 to 2012. The study also aims to discuss growth trends presented in previous papers to seek common factors and get a deeper understanding.Data for 1992, 2002 and 2012 on a sub area level supplied by Umeå municipality was used. The study shows a continued positive development across almost all sub areas, but a differing growth rate from centre to periphery, and also a diversified medium age among the inhabitants.While the city center continues to have the highest growth of population during the studied years, a recent trend seems to point to a growing popularity to settle in the outskirts of the municipality, primarily near the coast..
