Framtagning av fotometriska EULUMDAT filer från
belysningsmätdata för armaturer
Nordic Light AB tillverkar armaturer för bland annat butiker och utställningar. För att kunna avgöra vilken armatur som behövs för en viss applikation och för att se hur en viss armatur lyser har kunder efterfrågat fotometriska filer av formatet EULUMDAT. Fotometriska filer innehåller bland annat information om armaturers ljusfördelning. Den utrustning som Nordic Light AB använder i sitt ljuslabb kan mäta belysningsstyrkan i lux på en kvadratisk yta och sedan sparas mätvärden i en textfil med x- och y- koordinater samt belysningsstyrkor. Detta examensarbete har utförts för att ta reda på vad en fotometrisk fil av formatet EULUMDAT innehåller och om det med Nordic Light AB: s befintliga utrustning går att ta fram en sådan fil.
Kommunikations- besluts- och informationsflöden i byggprocessen
Construction projects are organized in different shapes and disturbances in the information flow in these processes can lead to problems, such as delays and/or a lower quality. Therefore, a well-functioning interaction between actors and a well thought out-communication at an early stage is of crucial importance. The main question is "How does the communication of decision and information flow in the building process and what barriers and opportunities can be observed?". This diploma work has been written with guidance from Bjerking AB and to answer this question, a collection of empirical data conducted via semi-structured interviews.
Habitat preference and dispersal of a sandassociated beetle, Apalus bimaculatus
Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.
Fallgropar och framgångsfaktorer vid användandet av viral marknadsföring: en fallstudie av två svenska företags virala annonskampanjer
The purpose of this thesis is to shine some light on how B2C companies in Sweden carry out a viral marketing campaign. Through case studies of two comparably sized companies, Arla and If Skadeförsäkringar, this was examined. This study shows that viral marketing is still a new subject for both marketers and researchers. It is hard to find conclusive methods for how to carry out such a marketing campaign successfully leaving companies feeling that they first have to go through a trial and error process. This is evident in this case study, where viral marketing is degraded to a tool for generating awareness rather than producing actual results as part of a holistic marketing plan and where those results are too uncertain to rely on.

Energi- och exergiflöden i stålframställningsprocesser vid
SSAB Tunnplåt AB i Luleå
Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.
Kognitiv auktoritet och Wikipedia ? En analys av gymnasieelevers källkritiska granskning av Wikipedia
The main purpose of this master?s thesis is to examine how high school students evaluate the quality of the information available on the online encyclopedia Wikipedia. By doing quantitative research based on questionnaires we expected to find that the means for judging that students use in this situation are most frequently based on a text?s intrinsic qualities in the point of view of its content. It was also our presupposition that 18 and 19 year old high school graduates have received some education in information research and authoritative sources on the Internet.
Gamification av digitalt lärande : En studie av attityder om spelelement i lärplattformar
Society today is characterized by the transforming effect IT has had, the majority of the activities we perform on a daily basis involves one way or another digital technology. One area which has not yet seen the positive effects of IT is education. Despite the progress of technology, the school education has barely changed since it first saw the light of day. Our goal with this study is to investigate the possibility of implementing Gamification elements in educational environments and examine whether it could increase our young students learning motivation. We believe that this kind of implementation will have a positive effect for these young people since they have been interacting with games since they were small and are familiar with the driving force of a reward system.With this study we want to examine the opportunities and challenges that Gamification implementation brings out in a learning environment and therefore encourage and motivate our young ones to study even harder..
