Det lärande mötet : En studie om lärares didaktiska medvetenhet i undervisningssituationer
The authors were curious and asked themselves if teachers are aware of the base of their teaching in various teaching situations. Are teachers at all capable of expressing that in words? One of the reasons that the authors chose the particular issue was because they think teachers have the task to satisfy the needs of all students and therefore they found it interesting to study how various teachers act. The purpose of the study is to observe teachers didactical awareness, and how it can be added to their intentions and actions, as in how they speak about their teaching and how they act in various teaching situations. Methods used in the study were observations and qualitative interviews.
Design and Analysis of an All-optical Free-space Communication Link
Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.
Valfrihet eller inte? : En kvalitativ studie av svenska riksdagspartiers motionerande över privatiseringen av skolan.
The aim of this work was to investigate how it is to move in hierarchy from crew toofficer within the seafaring profession and how to be affected by this. How you areperceived by the crew when going from to represent a part of a system to represent adifferent part of the same system and if you are ready to assume the responsibilities of thenew role entails?This is relevant and interesting as we will soon is facing at this transition. The work isbased on a qualitative approach. The choice of this method gave the information neededfor a perfect result.Interviews were conducted through personal meetings with active officers which alsoprovided the opportunity to ask follow-up questions and the respondents were given theopportunity to share their experiences.
Genus betydelse i fredsprocesser
Genusvetenskapen önskar att framhäva genus, med både fokus på enbart kvinnor och på maktrelationen mellan män och kvinnor, i fredsarbetet samt återuppbyggnaden av postkonfliktsamhällen. Kvinnor har länge exkluderats och ignorerats i fredsarbeten. I och med uppkomsten av resolution 1325, som syftar till att visa kvinnors avgörande roll i fredsarbete har genus blivit ytterligare accepterat i det internationella samfundet. Syftet med vår uppsats är att undersöka vilken betydelse genus kan spela i fredsprocesser. Genom att undersöka fallet Liberia och den fredsprocess som landet genomgår vill vi belysa de konsekvenser som genus har i denna fredsprocess.
Prognostisering av sättning frånhög uppfyllnad i Högbytorp : Numerisk?analytisk jäföelse samt uppmäta sätningar
The purpose of this thesis was to examine if users of digital music games may acquire skills from the games that may be of use in learning to play a real instrument, that is a non-digitally simulated instrument like an acoustic piano. We have used Gee?s theory regarding a possible interconnection between different semiotic domains, and how this connection may enable a transfer of skills between related domains. In this thesis we examine possible skill transfer between the domains ?digital games? and ?non-digital instruments?. To examine our question formulation we chose to conduct a pilot study from which we collected both quantitative and qualitative data.
Ethanol for Scania's Future - A Scenario Based Analysis
Abstract Title: Ethanol for Scania?s future ? A scenario based analysis Authors: Anna Hansson and Julia Persson Tutors: Annette Cerne ? Department of Business Administration, Lund University Jonas Holmborn ? Head of Advanced Combustion, Engine Development, Scania Lennart Thörnqvist ? Department of Energy Sciences, Faculty of Engineering, Lund University Problem: Oil-based products are the dominating fuels in the transport sector but alternative fuels are currently challenging the world-wide dominance. The large number of alternative fuels that are under development at present makes the future fuel-market impossible to predict. Scania?s ethanol project is associated with a number of uncertainty factors that are beyond the company?s control.
pH-sensitivity in boreal streams ? the influence of landscape characteristics
The goal of the society to increase the proportion of renewable energy has led to an increased demand of bioenergy e.g. forest biomass. However, there are concerns that removal of biomass will lead to decreased base cation concentrations in the soils and acidification of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse the relations between pH-sensitivity and landscape variables in the Bothnia Bay water district. GIS and digital geographical data were used to analyse the landscape in subcatchments.
Tylö : Sauna Lighting
Tylö AB is the leading manufactor of sauna cabins in Europe, but there is a lackof a sauna lightning produced by Tylö. The project of developing a new saunalightning series was assigned two students at the developmentengineeringprogram at Halmstad University. The main problem with lightning in the saunais the heat and security aspect. The selection fell on LED technology as thelightning source, thanks to its small measures and low heat emission.The work of constructing of a lightning armature which the capability of coolingdown the LED lightning was carried out during autumn ?06 and spring ?07.

E-handel i småföretag
E-commerce is a conception who many are taking about nowadays. E-commerce is associate with computer based business and it?s a new way to do business on. Users and system connect up to each other for effective mediate and transfer information. Within e-commerce there?s a lot of ways to do business on and it can for example be between a business and a another business (B2B) or between business and consumer (B2C).In this degree report have I reached if small business will invest on e-commerce and if they will, how.
Internationalisering av tjänsteföretag : En undersökning av svenska träningskedjors internationalisering
The study aims to investigate Swedish fitness companies positioning and strategic choices when internationalising in the Scandinavian countries and what has influenced this choice. Furthermore, the corporate risk and what obstacles they encountered will be examined.The study was conducted as a qualitative study with a deductive approach. The results are based mainly on primary data from interviews, as well as secondary data.The fitness companies? choice of strategy in internationalisation depends largely on its concept and positioning. The main obstacles in the internationalisation process are lack of communication, language difficulties and regulations.

The theory used is Fabrizio Battistellis motivation theory and a form of discourse analysis.
Grafisk representation av ljud
De senaste decennierna har en rad streckkodstekniker utvecklats för att grafiskt representera digital information. Gemensamt för dessa är en strävan efter hög densitet, det vill säga kapacitet att lagra mycket data på en liten yta. Densiteten begränsas emellertid av kravet på precision vid tolkning av den digitala datan, eftersom felaktigheter i digital data kan resultera i omfattande informationsförlust.Analog information, exempelvis ljud, är däremot inte beroende av exakthet hos underliggande data i samma utsträckning. En analog ljudsignal kan beskrivas och återges approximativt, och ändå tolkas korrekt av en lyssnare. Detta faktum gör att det finns fördelar med att representera ett ljud utifrån dess analoga egenskaper.
