Solenergi En del i ett långsiktigt, hållbart byggande
The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.
"Det finns inget bättre än en lärare som verkligen bryr sig om dig" : En studie om vad som gör gymnasieelever studiemotiverade ur elevens perspektiv
My purpose for this essay is to examine what factors are considered to have high influence on motivation to study and what measures can be taken to enhance student?s motivation to study from a student perspective. The main source of theory for this study has been the classification of motivational factors that has been based on Herzberg?s twofactortheory with complementary theoretical sources. The study is based around two research methods, one survey together with complementary student interviews. The empirical material consists of 118 completed surveys together with nine student interviews. The study?s results have found that students find the main source of rising motivational level originates from the professional role of the teacher. Additionally the students find the main source of subsiding motivational level originate from rising level of stress and uninspiring teachers.
Open access i forskningspolitiken : en undersökning av de politiska argumenten i debatten kring vetenskaplig publicering
This Master's thesis aims at pinpointing the political arguments that appear in the recent debate on scientific publication. There is a widely spread opinion that prices on digital resources are far too high, thus taking up a major part of the University libraries budget, while publishing companies make high profits. It is also a common opinion that the current publishing method does not take full advantage of the possibilities of electronic publishing. Lately a number of alternative ways of publishing have been initiated and discussed, generally referred to as open access. Open access published material is available free of charge and free of most copyright and licensing restrictions on the public internet.In this thesis the minutes from four hearings held by the UK House of Commons in the spring of 2004 are examined.

Vilken kommunikation smörjer börsmaskineriet: En kvalitativ studie av börsanalytikers syn på informationsinsamling och trovärdighet
Stock analysts have through the analyses they write a large impact on the expectations on the market and the direction of investors investments. This creates undesired fluctuations on the market that raises the level of uncertainty. The way that the analysts satisfy their need for information is connected to how their final analysis will be shaped. There is a large knowledge gap concerning the way that the analysts work and this gives unsatisfactory ways of communication. This thesis is set out to create a greater understanding of how optimal communication towards this target group should be brought out.
Effekt av brand och bete p? uppkomst av ?rtartade v?xter i restaurerade betesmarker. En j?mf?rande studie
Open ecosystems, such as grasslands and pastures, have naturally been shaped by disturbances like fire and grazing. These processes play a crucial role in creating habitats with high biological diversity, particularly favourable for a wide range of herbaceous plant species. In recent years, many of these disturbances have ceased, leading to encroachment, fragmentation and habitat loss. The aim of this study was to examine and compare the effects of fire, herbivory and a combination of fire and herbivory on the emergence of herbaceous plants. The study was conducted at the Ecopark at Nordens Ark.
Vad hör du? : ljudets betydelse för en plats
We are surrounded by sounds. There is always something that makes a sound: a breeze through the leaves, traffic on a distance or your own blood rushing through your veins. Human will always be surrounded by sounds which makes it an important part of our lives. Therefore the sound should have a big influence on how we perceive our surroundings and interpret our world. This essay inquires into what sounds can mean to an open space and urban spaces.
Analys av datakommunikationssäkerhet för VoIP-protokoll
Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common Open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..
Lindehults handelstr?dg?rd: en fallstudie med fokus p? j?rnv?gens nytta f?r en ?kad marknad
This case study's aim was to strengthen the state of knowledge about how horticultural
companies in Sweden used railway transports between 1900s and the 1950s. Economic
theories and a micro-historical perspective have been used to analyze the collected
source material, and to describe Lindehult's market garden. The investigation is based
on document analyzes, qualitative interviews, archive studies and literature studies to
evaluate the sources' information through a source pluralistic method. The work has
been based on historical source material in the form of payment vouchers, giving an
insight into how the company's products were transported by rail across Sweden. Sture
Hjalmarsson's diary and interviews have described the case and events that affected the
company internally.
WEBBSERVRAR : En jämförelsestudie mellan proprietär och Open source webbservrar
Nuförtiden är det mycket vanligt att människor och företag använder en hemsida för att synas. Hemsidor kan vara uppbyggda på olika sätt och av olika datorspråk, men de måste i grund och botten köras på en webbserver för att kunna fungera som en webbplats.Det här examenarbete undersöker prestandan för proprietär webbserver och webbserver som är av typen öppen källkod. Webbservrarna prestandatestades på hur väl de klarar av att distribuera olika sorters material som är vanligt förekommande i dagens webbsidor. Resultaten ifrån prestandamätningarna visar att webbservern av typen öppen källkod presterar i regel bättre än de proprietära webbservarna. En litteraturstudie genomfördes även för att se hur funktionaliteten för webbservern av typen öppen källkod kunde utvidgas.
Bevattning av lagrat virke vid svensk skogsindustri : omfattning och miljökonsekvenser
Most of the saw and pulp industries have stored wood nearby their production, the main
reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality.
One drawback of wet storage of wood is the leaching of chemical substances into the
surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and
organic substances. These substances can cause problems for the surrounding environment.
The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.
Open Source-baserad utveckling av Document Output Management-lösningar
Det finns flera fördelar med att digitalisera företagets affärsdokument; bland dessa kan nämnas minskade utrymmeskostnader och lättare delning av information. En process som inte sällan utgör en del av det elektroniska dokumenthanteringssystemet är hanteringen av dokumentmallar ? området som detta examensarbete kommer att fokusera på. Att på ett enkelt och smidigt sätt kunna förena data från ett affärssystem med en passande dokumentmall (kanske i form av en serverkomponent) och, baserat på denna process, generera t.ex. en faktura eller plocklista är något som varje elektroniskt dokumenthanteringssystem värt namnet borde kunna.
Jesu mor var där : En studie om barnbiblar, Maria och hennes relation till Jesus i Joh 2:1-12.
For centuries Islam and Muslims have been subject to islamophobic attitudes in the west. The purpose with this study was to see into the making of open and closed attitudes against Islam and Muslims from a conflict in southern Thailand, and also to so see if Muslims are portrayed as more violent than the Buddhist groups in the conflict. The aim of the study is also to see if Muslims fall into a violent stereotype. This was studied by looking at five Swedish newspapers coverage of the conflict, during a given time. To be able to look into this, two theories will be used, the first one is the Runnymede Trust theory, which is about open and closed attitudes against Islam and Muslims.
Fingerstyrka mot toppen
Klättring är en växande sport som kräver jämn balans av styrka, teknik och psyke. I dagslägetsker klättertävlingar och de hårdaste utomhuslederna på branta överhängande väggar med smågrepp. God fingerstyrka är nödvändigt att ha när klättring utövas för att kunna hålla sig kvar igreppen, som består av lister, på väggen. Då dessa lister tas används en greppteknik somkallas för crimpteknik. Det går att hålla i listen i denna teknik med tre olika positioner, closedcrimp, open crimp och open hand.Syftet med denna studie är att kartlägga skillnader mellan olika test av prestationsförmåga ochcrimputhållighet, undersöka vilken crimpposition som går att hänga längst i samt utforskakorrelationen hängtid i crimp med styrkeövningar.Tjugotvå manliga klättrare rekryterades och indelades efter inrapporterat personbästa i tregrupper (elit, avancerad och normal).
"Prata högre! Jag hör inte vad du säger" : En kvalitativ studie om elevers och pedagogers upplevelser av Södertäljes nya skolmodell
"Speak up! I can?t hear you"This qualitative study is built on an investigation of a newly instated model that is used when building or renovating schools. The principles of the model are based on building schools with an open plan design where the walls are made of glass and the classrooms are not shut closed by walls, instead the classrooms are completely open except from screens that are used to indicate the ambit of the rooms. This model has been well debated and that is the reason why we chose to do this study.The purpose of this study is to find out how students and teachers experience this model. To do this we have done interviews and observations.
