This study has investigated how urban vegetation can be used in a multifunctional way to support ecosystem services in urban environments. Nacka municipality is in the start-up phase of building what is to become Nacka city. This provides a unique possibility to study and analyse what role the vegetation play in making the city a healthy living environment and how it needs to be adapted in order to be resilient against changing climate conditions and how the effects of those changes can be regulated. The study further investigates how airborne pollution, caused by urbanization processes, can be regulated or reduced by vegetation or species selection. Methods used in this study were a combination of qualitative interviews and literature studies, seeking to answer the questions: Which specific ecosystem functions are needed in the urban environment and which aspects will influence the ecosystems ability to deliver the functions in demand? And which plant species have the right mechanisms needed to deliver those functions? These questions have been studied and analysed in a local based context where the local conditions ands site specific needs of Nacka define criteria for plant selection.

Kundnöjdhet är en stor inkomstkälla för företag. Det finns många sätt att mäta kundnöjdhet och ett av de nyaste sätten är genom en digital monter placerad i fysisk butik. Denna studie ämnar undersöka hur gränssnitt till en undersökningsapplikation skall utformas för att tilltala en bred målgrupp att lämna omdömen och hur ett användbart gränssnitt till den administrativa sidan för denna applikation kan utformas. Resultaten från utvärderingen av undersökningsgränssnittet visar att det finns designelement som tilltalar vissa användare mer än andra. Detta ger en fingervisning om hur design kan utformas för att vara tilltalande för användarna att lämna omdömen via teknisk plattform.

Det här arbetet utreder en alternativ metod för mätning av varvtal hos likströmsmotorer. Det är idag vanligt att man använder sig utav givarlös feedback i reglersystem för att nå lägre produktkostnader. Nackdelen med metoden, som utnyttjar den över ankarlindningarna inducerade spänningen (back EMF), är dålig precision jämfört med system med varvtalsgivare. Denna alternativa metod utgår ifrån att motorströmmen varierar periodiskt med varvtalet på grund av asymmetrin i motorn. Genom analog filtrering av motorströmmen samt digital signalbehandling som arbetar utifrån autokorrelation är det möjligt att skatta varvtalet utan givare.

Under vårterminen 2011 har jag studerat hur ett verktyg påverkar en arbetsprocess. Från en idé har ett projekt vuxit fram och två ljudbanker för musikproduktion har producerats, detta har gjorts möjligt genom att jag har studerat digital ljudproduktion på Blekinge Tekniska Högskola, där intresset för det som blivit mitt kandidatarbete, har väckts till liv. Mitt kandidatarbete har resulterat i två ljudbanker, den ena banken har fokus på digitala trummor medan den andra har fokus på synthar. Slutreflektionen berättar hur denna process har gått tillväga, och hur resultatet blev. Jag för fram för- och nackdelar av arbete i Dune, hämtar fakta från kända producenter inom elektronisk musik och bedömer det resultat jag har får. På både gott och ont har dessa två ljudbanker blivit två produkter.

Information technology (IT) have for several decades been used in university education. An increasing number of classrooms today are built around a concept which uses IT in collaboration with the room itself. However, little is known about the experience of university teachers when working in such classrooms. This study examines the views and opinions of teachers at a Swedish university regarding using and interacting with these classrooms. Furthermore, we identify possible underlying factors that influence these views.

The purpose of this study is to investigate what five primary teachers in five different schools with many second language students have for an idea about inclusion, language development, practices and environment of the multilingual classrooms. In my study I discusses teachers 'views on the multilingual classroom, inclusion, development of language in a language developing classroom environment and the importance of language skills has for multilingual pupils' language development and learning of the Swedish language. The method used was unstructured interviews using a digital recording device. The results showed that for these five teachers, meeting second language learners was in there everyday teaching, while it is a challenge to motivate and support them on their level. The teachers work diligently to find a balance and a working classroom environment for the multilingual classroom where all students, regardless of conditions, background, experience, knowledge and language could be offered an equal opportunity to education. .

This paper is about the use of task boards in agile system development projects. The main focus is on how digitalized versions of the task board can be of assistance during the development process. Our investigation is based on qualitative studies, with system developers of various backgrounds and professional roles, along with studies of relevant literature. The main results are that a digitized version of the task board can increase awareness for the team and be of major importance if it is accessible through the web. On the other hand negative effects of the digitalization can emerge as well.

The purpose of the study was to determine the attitudes of the teachers of Reggio Emilia inspired preschools concerning the science work with children between the ages of one and three, as well as their opinions on how the physical preschool environment and the choice of materials influence their scientific work. The study was conducted in three departments of two different kindergartens. Although both kindergartens called themselves Reggio Emilia inspired, their working methods and their environments differed largely. None of them were originally built as Reggio Emilia inspired preschools. One of the kindergartens strived to design their indoor environment the same way as the preschools of Reggio Emilia are constructed, there for they were setting up different stations where the children themselves have the opportunity to explore various scientific areas.

Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

This essay examines a small selection of Swedish newsreel and documentary short films, primarily travelogues, produced shortly before and after the second world war. The general aim is to expose differences in the representation of ?The Other? and the ?ethnic Swede? by applying a critical discourse analysis. The purpose is to illuminate how the material positions the latter as the norm and then contextualize this with xenophobic currents that had developed up until the middle of the twentieth century. Theoretical and methodological framework is drawn from the field of cultural studies as well as the nonfiction film.

Nimo Verken AB is the leading producer in the Scandinavia of drying cabinets. The construction has, with small changes, been the same since the 70s with a thermostat and a timer as controlling system. There was a wish to develop a modern cabinet which showed remaining time on a display and with energy saving functions.In this report we go through how it is possible to implement a digital controlling system, where remaining time is shown on a display and where it is possible to choose a preset ?program?.The report first presents the fundamental theory for a PIC, where we describe the different registers, how interrupts are handled, the internal clock function and how data is sent to control the different parts of the construction.Next the report presents and describes the new hardware that is needed, such as the encoder, the temperature sensor and the display.After the theory we describe how the program in the PIC may be drafted. Last in the report we have the result of the tests of the temperature variations and the accuracy of the time..

AI är något som blir allt viktigare inom dagens spel och får allt högre krav på att agera mänskligt och intelligent. Detta kandidatarbete undersöker vilken metod som är att föredra för att skapa en AI som kan lära sig av sina tidigare erfarenheter. Några av de metoder som undersöks är trädstrukturer, Artificial Neural Network och GoCap. Genom att skapa en applikation med en av metoderna samt göra en undersökning på hur AI:n i applikationen upplevdes fick vi resultat om denna metod var användbar. Utifrån detta diskuteras det ifall andra metoder hade varit mer effektiva, hur man hade kunnat förbättra AI:n samt hur framtiden för spel-AI skulle kunna se ut..

During the last two decades, technology has developed rapidly. It has become a natural part of everyday life, which we today take for granted. It isn?t until the last few years that technology has quickly become a big part in the school environments. Computers, tablets and other technology is today a big part of the education and teaching.

The main aim of this study was to investigate and compare different methods for the extraction of forest fuel from environments close to an archipelago. The study was based on relevant literature and published reports as well as personal communications. Forestry has traditionally been characterized by intense efforts to rationalize and mechanize the cutting technique used for timber and pulpwood. In line with the increasing importance of forestry, more concentrated efforts can be expected in the area of techniques and methods, especially for the above-mentioned product lines. In Sweden, forestry is of major importance and the Swedish economy and standard of living have mainly been created based on the revenues generated from it. Thus, it is vital that Swedish forests are harvested in an efficient and responsible manner. The demand for biofuel is growing and today accounts for 15% of total Swedish energy production, a share that will probably increase. This study is based on three research questions, which are described under the heading of Aim. The results reveal that the most profitable method for handling forest fuel is the traditional one, which is also the most commonly used method in southern Sweden, namely the stockpiling of logs in a clearing by means of forwarders followed by splintering at the place from where they will be distributed. Today, the high cost of barge transport required for the extraction of forest fuel in an archipelago environment renders such operations unprofitable.
