Pre-treatment of grain for ethanol production during storage
Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.

Studie av beslutsprocessen vid anskaffning av ett IT-system
Arbetet ett företag lägger ner för att komma fram till ett beslut om en större investering i till exempel nya maskiner är oftast omfattande och ett resultat av ett strukturerat arbete med klara strategier för att i största möjliga mån uppfylla behovet som orsakade anskaffningen. Däremot har en investering i informationsteknologi av olika anledningar inte setts som vanliga investeringar utan ofta genomförts utan en ordentlig utvärdering. Med denna uppsats ville vi försöka ta reda på om det verkligen förhåller sig så att företag anskaffar IT-system utan att göra någon ordentlig analys av de problem eller behov som förorsakat anskaffningen eller om de följde de metoder och modeller som finns tillgängliga för att komma fram till ett beslut om anskaffning av ett IT-system. Vi utförde vår undersökning vid tre produktionsföretag som hade anskaffat liknande system. Vid vår analys valde vi att applicera förändringsanalysmetoden, FA/SIM och Simons vedertagna beslutsprocessmodell på det empiriska materialet.

Examples are lack of a system for labelling shelves and racks, lack of an efficient location system and development possibilities in work routines. For the empirical investigation both qualitative and quantitative methods ware used.
Sjung för, sjung med och sjung till barn : En studie om hur musicerande situationer förekommer på tre olika förskolora ur ett språkutvecklingsperspektiv
In 1998 years' curriculum for the preschool stands it those children under school age will get possibility that? communicate with the aid of differently expression shapes? and an example that is mentioned in the governing document is song and musical. The purpose with this study is to examine how the song and the music are used from a language development perspective in three different preschools' activities. In the essay, I review to earlier research around the music?s' and the song's possibilities for the child's linguistic development. In the essay, it is discussed about some important factors that obstruct music situations in the preschool that the curriculum for the preschool (Lpfö98) not specific describes what expression shapes as song and music will contain and that deficiency on musical education at pedagogues. The method for the study was to collect empirical materials through observations on three different preschools.
Minoritetsspråkliga elevers undervisning : En jämförelse mellan svenska och norska styrdokument
Many students in the Swedish and Norwegian compulsory school do not have qualification to search for further education. There is a large part of those pupils who have a different native language than the country?s majority language. These students? possibilities to a fair and equal education is regulated in national laws and regulations of school activity, the so-called governing documents. The purpose of this study is to compare Norwegian and Swedish governing documents regarding education for pupils with another native language.
Samband mellan lågt tryck i dricksvattenledningar och magbesvär - En utredning av hur lågt tryck på dricksvattenledningsnätet vid lagning av läckor påverkar sjukligheten hos Göteborg Vattens abonnenter.
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
Framtiden är rörlig!
Företag behöver öka farten på införandet av mobila system för att kunna hänga med i den hårt ökande konkurrensen och globaliseringen som sker. För att satsa pengar i ny teknik är det dock viktigt att se tydliga affärsfördelar med investeringen. Här saknas kunskaper och medvetenhet hos företag om möjlig effektivisering som mobila system kan medföra i verksamheter. Syftet med undersökningen är att utvärdera Pågens mobila system utifrån ett organisatoriskt effektivitetsperspektiv. En fallstudie på Pågen AB har genomförts där effekterna av införandet av deras mobila orderhanteringssystem utvärderas.
Uppföljning av system för vägentreprenörer i skogen
Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development.
The study is largely based on interviews with road contractors that perform work for Holmen Skog today.
Gråzonens barn -En studie i gränslandet mellan normalitet och avvikelse, mellan individen och kollektivet
The purpose of this study is to research into the role of the citizen and the educational system in Sweden throughout periods of time based on previous theoretic works, and also to deepen the understanding of students with special needs in Swedish education focusing on the primary school years. This shall be carried out by illustrating the different points of view and choices within the educational system that are at hand for students with concentration difficulties and social difficulties.I will analyze these points through a cultural and social perspective on contemporary society in order to contribute towards today?s discourse on the norm. The result of this empirical investigation presents a dilemma existing in the democratic educational system of today. Nationally and internationally, the educational system has been structured around a normative system containing both rights and duties that effect everyone working within it.

Undersökningen hargjorts genom att ta fram en bokningsprototyp och resulterade i för ?och nackdelar,användningsområde och hur CQRS, Event Sourcing och händelsebaserat gränssnitt kanimplementeras tillsammans..
Utveckling av ett hjälpmedel för träning och utvärdering av förare av tunga fordon
The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.
Karakterisering av bioslam för modellering av biogasproduktion
The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.
Uteslutning och inneslutning : En observationsstudie om hur förskolebarn skapar kamratrelationer
Preschool is an important social arena for children. This might be the first time that children find themselves in a larger social context and create their first peer-relations. The aim of this study was to examine children?s peer-relations with particular focus on the acts of social exclusion and inclusion, and how children use different strategies to exclude and include each other. Another aim was to investigate how both verbal and non-verbal communication is used in these processes.This study has an ethnographic approach, and the use of video observation as a method enabled us to capture the children?s everyday interactions at preschool.Our results show that children use a number of different strategies to exclude other children that seek access to an ongoing activity to protect the interactional space that they already share.
