In this report a study has been done regarding different heating systems on which are the mostcomprehensive with solar heating systems. The report has also been focusing if solar power can beused as a primary heating source for supplying more than 50 % of the buildings total heatingproduction. The University of Dalarna constructed a demo-house for this purpose and according tocalculations the total solar usage is more than 50 %. This house has been made for referenceregarding the design of the heating system of property 5:37.Further studies have been made to compare different heating systems that are compatible with asolar system, where the compared systems purpose is to be independent of direct using electricity. Asystem of this design is regarded as sustainable according to environmental as economic issues.

Dagens digitala spel är oerhört komplexa produktioner som ofta kräver en multitud av  sofistikerade verktyg för att förverkligas. Ett intrikat nätverk av moderna lösningar där såväl  visuella som audiovisuella element samverkar för att frambringa fängslande och entusiasmerande  upplevelser är vad som gör dagens spelproduktioner, och ingen annan bransch har sett samma  raketutveckling som spelbranschen sedan dess begynnelse. Ljuddesignens roll i digitala spel har  dock förblivit passiv där andra element tagit an mer dynamiska roller i varierande form.  Generellt sett är ljudet oftast mer ett komplement till de visuella elementen än ett fristående  förmedlingsredskap. Då audiovisuell kommunikation ej delar vissa av de begränsningar som  visuell kommunikation innehar, såsom grafisk processeringskraft, bildskärmsavgränsningar etc,  så ser vi att ljuddesign besitter en stor mängd outnyttjad potential som i teorin hade kunnat  förgylla spelupplevelser kolossalt.Det här arbetet undersöker både genom analoga och digitala medel hur införandet av binaural  lyssning i spelproduktioner kan förbättra navigationsförutsättningarna för användaren avsevärt  då djup och höjd kan skildras mycket mer effektivt, samt hur dess applicering i tredimensionella  miljöer kan främja såväl nöjes­ som lärosyften i så kallade Audio based Environment Simulators  (AbES).

The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

this paper is a study on children's social interactions in role-play. The aim is to try to highlight how children with other develop social skills and how to further motivate children tosee, understand and manage their reality in role-play by highlighting the characteristics of afunctioning role-play. I would also highlight the importance of pedagogue´s role in relation tochildren's social skills in role-play. The purpose flows into these issues, what distinguishes afunctioning role-play? Can the children in role-play influence their thinking to developunderstanding of others and the environment and if so, how? What significance does pedagogue´s role in children's role-play? I used out of a qualitative methodology to carry out this investigation.

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

I mitten av 1990-talet närmare bestämt 1996 gjordes en film kallad Diary of a Camper. Filmen handlade om en person som satt och lurpassade på sina fiender i ett datorspel. Det som var speciellt med denna film var inte handlingen eller något fantastiskt kameraarbete. Nej det som var speciellt var det faktum att filmen spelades in i ett datorspel. Denna film anses vara startskottet för machinimakulturen som idag omfattar flera tusen utövare världen över.Det var personerna bakom Diary of a camper som myntade uttrycket machinima som är en sammanslagning av de engelska orden ?machine? och ?animation? alltså maskin och animation.

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

Särskolan är en skolform för elever med utvecklingsstörning. Gymnasiesärskolan tillhör särskolans frivilliga skolform och erbjuder en fyraåring utbildning för ungdomar i åldern 16-20 år. Den har samma läroplan som gymnasieskolan. Under de senaste åren har det skett en ökning av antalet elever som skrivs in i särskola. Den största procentuella ökningen har andraspråkselever stått för.

This study aimed to evaluate the levels of formaldehyde and organic acids that can build up within enclosed spaces. Another goal was to compare two types of paints that can be used as coating barriers within showcases and in turn compare them to the modern, and by many highly recommended, material of Marveseal®. A low volatile waterborne alkyd/acrylate paint and a two component polyurethane paint was compared to Marveseal® in two series of experiments. One series measured the level of formaldehyde, and thus the effectiveness of the three chosen barriers, and the other series measured the level of volatile organic acids, both the acids emitted from the paint itself, and that of the wood. One box in each series were not treated at all and was used as a reference.The fact that different types of materials emit volatile organic compounds have long been known.

The last decades the populations of wild boar (Sus scrofa) has increased rapidly over the species? entire European range, including Sweden. This is followed by increasing human-wildlife conflicts as a result of the wild boar foraging behavior, causing damage to agricultural crop fields due to trampling and feeding. To be able to minimize damage we need more knowledge of where in the fields the risk of damage is high and what features in the landscape that affect this risk. I analyzed damage distribution in relation to the distance to six different landscape features; forest, road, ditch, building, game field and bait station, in the study area, the Island Mörkö in eastern central Sweden.

This Master Thesis has been conducted as an assignment of the Swedish Defence MaterialAdministration and the Swedish Armed Forces and aims to examine the Target Location Error(TLE) of a Forward Observer System. The targeting accuracy of the system is vital if the systemis to be used as a sensor for precision munitions. The analyzed system, EOI (FOI 2000), wasdelivered to the Swedish Armed Forces in 2007. The targeting sequence starts with deciding theposition of the system with a GPS-receiver, continues with methods where the north direction issettled and ends by measuring the distance, direction and elevation to the target. When allparameters have been measured the system calculates the position of the target.

Problembakgrund och problemformulering: Komponentavskrivningar är en del av BFN:s allmänna råd som även kallas K3, vilket blev tvingande från och med år 2014. Vi har i denna komparativa studie behandlat hur familjeägda och kommunala fastighetsbolag tillämpar komponentmetoden, eftersom de kan ha olika skäl till förvaltning. Vi kom därför fram till följande problemformuleringar: Vilka kriterier har familjeägda respektive kommunägda fastighetsbolag vid identifieringen av antal komponenter? Hur förhåller sig dessa fastighetsbolag till begreppet rättvisande bild i samband med valet av antal komponenter?Syfte: Syftet med den här studien är att utveckla en förklaringsmodell för vilka kriterier familjeägda respektive kommunägda fastighetsföretag beaktar vid urskiljning av antal komponenter enligt K3-regelverket.Metod: Studien har ett explorativt syfte eftersom området är outforskat. Studien har genomförts med en triangulering, där vi först gjorde en pilotstudie där vi tog reda på om fastighetsbolagen hade tillräckligt med kunskap för att svara på våra frågor.

Detta examensarbete, som skrivits inom området media vid Konstfack ägnas åt tonårskillars sociala lärande i strategispelet League of Legends. Jag har undersökt hur ungdomarna kommunicerar med varandra och vilka olika metoder de använder för att inskaffa kunskap som är nödvändigt för att utvecklas som League of Legendsspelare. Jag har utgått från kvalitativa intervjuer med tre femtonåriga killar och etnografiskt orienterade videodokumentationer som bas för min undersökning. Socialsemiotisk teori med ett multimodalt perspektiv används. Begrepp som jag använder mig av för att förstå och analysera min empiri är lärande och design.Analysen av intervjuer och videodokumentationerna vägleds av mina frågor kring hur ungdomarna lär sig av varandra och vilka resurser de skapar tillsammans.

Crop efficiency in utilizing available nutrients is an important factor in increasing produc-tivity and reducing the environmental impact of agriculture. Nitrogen is the nutrient that plants need in the largest quantity and wheat, along with maize and rice, is the world's most cultivated crop. In this work, the Nitrogen Use Efficiency, NUE, during the major growth period, HTP, of twelve different spring wheat varieties, were examined. The NUE was calculated as the product of uptake efficiency of nitrogen, UN, and the conversion effi-ciency of nitrogen to biomass, EN. The purpose of this work was to find if there are varietal differences in NUE and its components among the twelve varieties and to link a high NUE to specific characteristics of the varieties.
