Utomhuspedagogik : Ett sätt att motivera elevers inlärning
The overall aim with this study is to elucidate outdoor education as an education method and on the basis of that illustration to examine active educators vision on it as a way to motivate students' learning. This study is based on a literature component and a qualitative study through interviews five teachers.The results of the interviews show how to interpret the motivation and how to work with students' motivation. As well as outdoor education as part of the activity. The interviews show the importance of outdoor education can be to increase students'motivation for learning. They also show the importance of outdoor education is for student learning and test scores have shown the effectiveness of student learning through outdoor education.
Biogas på Wapnö : Analys av framtida energisystem
Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.
Den globala uppvärmningen i skolans läromedel : En jämförande studie av sponsrade och förlagsutgivna läromedel
Today the talk about global warming and climate change are on top of the public agenda. There for schools and schoolbooks also debate the issue of global warming. A newcomer on the school stage is the sponsored school materials that studies show to be a growing phenomenon. In a debate like that of global warming which is filled with uncertainties and so much political and economic interest, I find it interesting to study how these schoolbooks talk about the issue.In my study I have tried to analyze and compare how school materials for primary school discuss the phenomenon of global warming. I have compared two different types of schoolbooks.
En precisionsstudie av förstärkt verklighet som positioneringsverktyg
This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.
Gaspotentialen i en deponi, idag och i en framtid :
Deposited waste material degrades within a short period in anaerobic environments. The
methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas.
In this thesis the amount of produced methane gas at the landfill at Örebro has been
calculated. Estimations have also been made of the amount of methane gas that might be
produced in the landfill in the future.
Förnybara bränslen är lösningen, vad är problemet? En maktanalys av den svenska dagordningen för förnybara bränslen
The aim of the thesis is to examine how central collective actors in the Swedish subsystem of renewable fuels use their positions of power and influence to their own specific interests and needs. In particular the thesis looks at the problems of climate change and oil scarcity and how renewable fuels are described as a potential solution. Using agenda setting theory and Steven Lukes three dimensions of power as a framework, five actors are examined and analysed. The study has been done in two parts. In the first part policy documents are analysed concerning the actors general stance towards renewable fuels, and how this is communicated to the media, politicians and public.
Motorik inomhus? : En intervjustudie om pedagogers användande av inomhusmiljön med avseende på barns motoriska utveckling
Vårt syfte med studien är att undersöka hur pedagoger arbetar med barnens motoriska utveckling i inomhusmiljön. Vi använder oss av kvalitativa intervjuer med pedagoger i förskolan och skolans förskoleklass till år tre. Det vi är intresserade av är pedagogernas tankar kring användandet av sin inomhusmiljö med avseende på den motoriska utvecklingen hos barnen samt för att se eventuella skillnader mellan verksamhetsfälten. Våra intervjufrågor behandlar fyra huvudområden, användandet av inomhusmiljön, vilka aktiviteter som genomförs, förhållandet till läroplanerna och motorikens betydelse. Resultatet visar att pedagogernas arbetssätt i förskolan och skolan skiljer sig en del inom dessa ämnesområden.
Regeringens miljösatsningar och deras förhållande till en hållbar livsstil hos det svenska folket : En studie av biståndssatsningars påverkan på hållbar livsstil i givarlandet
Swedish government aid is divided into three main themes: democracy and human rights, the environment and climate, and gender equality and women's role in development. These three themes in aid are considered by the government to be vital in order to fight poverty and create fair and sustainable development. This study will examine two of the four focus areas designated under the theme of "environment and climate". The study observes the relationship between projects in energy and water and how it promotes a sustainable lifestyle. A survey on environmental habits will be conducted.
TexTV
Syftet med denna rapport är att undersöka om det går att integrera en inomhusantenn i ett textilt material. Rapporten utgår från en design breif från företaget Teracom Group som är en del av kampanjen ?The Optimal Indoor Antenna?. Problemet som uppstått är att Boxer Danmark anser att den danska populationen inte tycker att de befintliga inomhusantennerna är tillräckligt estetiskt tilltalande. Detta problem har det forskats kring genom litteraturstudier, empiriska studier, material- och designstudier samt produktutveckling.
Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde
Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.
Omega - En passiv och vacker tillvaro : Ett passivt bostadshus
Idag projekteras byggnader för att spara energi och minimera värmeförluster som sker genom klimatskal. För att kunna minska behovet av aktiv uppvärmning för de boende utvecklades en idé om att byggnaden skulle uppvärmas med hjälp av passivvärme. Detta ledde till skapandet av passiv och lågenergihus.Det har funnits passivhus i mer än 20 år och vanligen används denna princip av privatvillor. På senare tid har dock passivhustekniken börjat integreras vid uppförandet av flerbostadshus. Syftet är naturligtvis att minska årsbehovet av aktiv uppvärmning för byggnader och samtidigt minska värmeeffektbehovet.

Perceptions of domestic solar systems : a study on non-adopter views of a new technology
The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany.
The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.
Sverige 2112 : Ett narrativ om hur arkitekturen kan utvecklas om världen går igenom stora förändringar på grund av klimatförändringarna. En linjär och vertikal stad.
Om världen till följd av klimatförändringarna blir mycket varmare kommer förutsättningarna för hur vi planerar städer, infrastruktur och jordbruk helt att vändas upp och ner. De delar av världen som idag står för världens livsmedelsproduktion kommer vid bara några graders förändring bli obrukbara som betes och odlingsmark. Dessa förändringar kan komma att starta konflikter, och stora flyktingströmmar som tillsammans med förändrade klimatzoner helt kommer att rita om världskartan. i Skandinavien är det då troligt att vi behöver bygga samhällen och städer för miljontals nya immigranter, och detta samtidigt som vi befinner oss mitt i den mest fruktbara jordbruksmarken i världen. Om hundra år måste vi dessutom, oavsett detta, dubbla livsmedelsproduktionen globalt sett.Vårt samhälle blir allt mer rörligt och infrastrukturen utvecklas i allt snabbare takt.
Adaptiv temperaturreglering av bostadshus
The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.
