Pedagogers resonemang kring inomhusmiljön på en Reggio Emilia-inspirerad förskola
Valet av denna studie gjordes utifrån vårt intresse för och nyfikenhet på förskolans inomhusmiljö och Reggio Emiliafilosofins sätt att se på barnet och människan. Syftet med studien var att beskriva och analysera fyra pedagogers utsagor och resonemang kring inomhusmiljöns utformning på en specifikt utvald Reggio Emilia - inspirerad förskola. Avsikten var att försöka fånga bakomliggande tankar av betydelse för utformningen av inomhusmiljön ur ett pedagogperspektiv. Undersökningen baseras på fyra kvalitativa intervjuer med stöd av observationer. I litteraturgenomgången beskrivs Reggio Emiliafilosofin och hur den ser på barnet och lärandet, miljön och organisationen av den, avdelningar indelade efter barnens ålder samt materialets roll.
Elektromagnetisk och mekanisk design av en 20MW turbogenerator
At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.
Lyftredskap för KL-trä - Hantering av horisontella och vertikala element i massivträ
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
"Fenomenalt" eller "De borde kunna mer om datorer" : En undersökning om datorhjälpen på högskolebibliotek
"Outstanding" or "They ought to know more about computers" : A study on computer support at university libraries.The main purpose of this study is to investigate the support computer users are given at university libraries. Further, the aim is to find out if the users thought they received the support that they needed. The study is carried out at two different university libraries. The data is obtained through interviews with the librarians, observations of the daily work at the information counters and questionnaires handled out to the users.The study indicates that variables such as knowledge, time and equipment play a central role in making the computer support successive. To a great extent the computer support is synonymous with information search, but it also deals with word processing and technical support connected with computer errors.
Komprimering av testdata för SOC : -En implementation av metoden vector repeat
Sammanfattning:De ökande testdatavolymerna som krävs för att testa moderna System-On-Chip (SOC) bidrar i hög grad till den ökande produktionskostnaden. De stora testdatavolymerna kräver stora och dyra Automatic Test Equipment-minnen (ATE-minnen). För att minska behovet av dessa minnen så har olika komprimeringsmetoder utvecklats.Denna rapport beskriver arbetet med att implementera en given komprimeringsmetod för testdata till SOC. Den metod som används heter vector repeat och den implementeras genom skapandet av ett för ändamålet avsett dataprogrogram. För att vector repeat ska fungera effektivt så förutsätts det att in- och utgångarna på den ATE som används kan delas in i olika portar.
Skarven : ? Produktutveckling av en oljedimavskiljare
This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
The capability to understand customer value - A case study of Metso Mining over continents
The purpose of this thesis is to describe and analyze how the mining equipment producers on a global market manage to handle the changing conditions concerning customer value. Our approach has been a comparative analysis between two different sites in order to answer the purpose. The case studies at Metso Mining have been made through interviews and visits at two geographical markets, South America and Scandinavia. The theoretical framework applied on our empirical findings is based on Blue Ocean Strategy, Customer Value and Resourced Based View. The empirical foundation is based on interviews with Metso Mining employees at Sorocaba in Brazil and Kiruna/Gällivare, Trelleborg and Staffanstorp in Sweden.
ABC och ekonomisystem : En studie av Volvo Construction Equipment Components AB
The accounting information system comprises budgeting, accounting, and costing. The accounting information system has, traditionally, constituted an integrated system where the different elements collaborate. If ABC is introduced this order is disturbed, since ABC is based on another logic which cannot easily be integrated with budget and accounting. ABC, therefore, is usually used parallely to the conventional costing method. There are, however, companies that have taken its ABC one step further by letting it replace the old costing model and integrate it with the accounting information system.
Brandsäkerhet i ett småhus
This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.
Brandskyddet i Göteborgs Hamn AB:s Energihamn : Ett projektarbete i fallstudieform för Göteborgs Hamn AB, som undersöker vilka förväntningar personal vid rederier och fartygsbefäl har på brandskyddet i Energihamnen, en hamnanläggning i Göteborgs Hamn AB.
Detta uppdragsbaserade arbete är en del av ett stort projekt som Göteborgs Hamn AB driver, vars syfte är att förnya det nuvarande brandskyddet i Energihamnen och även möta framtida krav. Syftet med föreliggande studie var att undersöka vilka förväntningar personal vid rederier och fartygsbefäl som regelbundet anlöper Energihamnen har på Göteborgs Hamn AB:s brandskyddsutrustning och brandberedskapsplaner. Vidare undersöktes vilken brandskyddsutrustning några av de tankfartyg som regelbundet anlöper Energihamnen har ombord, även vilka krav som ligger till grund för den utrustningen. För att få svar på ovanstående syfte kombinerades intervjuer med personal vid tre rederikontor och fem fartygsbefäl från samma rederier med en litteraturstudie. Litteraturstudien består av en sammanställning av de regelverk som ställer specifika krav och rekommendationer för det brandskydd som ska finnas ombord på tankfartyg.
Digitalisering av kulturarvet En studie av digitalisering vid två museer
The purpose of this thesis is to examine how two separate museums have realised the task of digitizing their collections, as well as to learn what options, possibilities and resources have been available to them during this process. Additionally, the aim here is to find how the two museums have dealt with problems in connection to the digitization projects, since there are as-of-yet no established regulations or standards to guide them in their digitization efforts. However, national and international working groups seeking to establish better collaboration between archives, libraries and museums ALM institutions have recently begun to formulate recommendations and suggested standards. Some of these recommendations have been used here as a theoretical framework in the examination of the two museums. The research questions posed are: What options, possibilities and resources have been available to the museums in their digitization projects, in terms of economy, staff, technical equipment and time?; For what purpose are the museums digitizing their collections?; and How does their purpose influence the process and chosen procedures? Also discussed here is how the museums relate to some of the existing recommendations.
Lantbruk i framtiden : ett praktikfall
The economic prerequisite to many farmers in Sweden after the EU membership and the
new agriculture policy has generated large demands on the farm management. Until year
2004 you got a grant based on what you had produced and not on consumer demand. In
2005 a new economic aid (Mid Term Revue) was introduced and the conditions has
changed again. Due to this I have chosen to do a cost-benefit analysis on a case, to
investigate if the present production is sustainable in the future.
My conclusion is that the profitability is acceptable even if the farm has a high debt. But
to make the production more profitable the products produced should be refined as much
as possible at the farm, to get maximum economic return.
Åsktransienter och överspänningar : En spänningsfylld simulering av elkraftsystemet vid Forsmark 3
A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.
Internprissättning "Betydelsen av situation och syfte"
När ett företag inför decentralisering medför det att det uppstår mer eller
mindre självständiga enheter, som ofta handlar internt med varandra. Genom
decentralisering vill företagen korta ner tiden för beslutsprocesser och ge ett
större ekonomiskt ansvar för varje enhet, man vill med detta nå en
effektivisering inom företaget. Problem som kan uppstå vid decentralisering är
att samordning och kontroll av enheter försvåras. Dessa problem försöker
företag lösa genom att införa ett internprissystem. Internprissystemet byggs på
företagets specifika situation och dess syfte med internprissättningen.
Internprissättning är ett komplicerat område, men det handlar om att kunna
styra, kontrollera och motivera de självständiga enheterna.
Implementering av en PSS i Trängslets kraftstation
The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.
