Bostaden – sedd ur kvinnligt perspektiv

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen

Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.

General Causality Orientation och Myers-Briggs Type Indicator: En studie av sambandet mellan två modeller för att mäta motivationsorientering och personlighetstyp

Varje år genomförs ungefär 3,5 miljoner personlighetsprofileringar med Myers-Briggs Type Indicator®, MBTI ®. Det gör instrumentet till ett av de mest använda psykologiska testen i världen och det innebär att lika många människor får en etikett på sin personlighetstyp som kan användas på olika sätt. Det finns studier, till exempel av Carlyn, som talar för att MBTI är ett pålitligt instrument, men det finns också studier, till exempel av Pittenger, som hävdar motsatsen. James Michael menar att enbart MBTI ger en alltför inkomplett bild av en ledares beteende. Kanske är det klokt att komplettera MBTI med andra testinstrument för att få en komplettare bild av en individ. En modell som skulle kunna komplettera MBTI är motivationsteorin Self-Determination Theory, SDT, och tillhörande delteori General Causality Orientation, GCO.

Doseringsmaskin Preplant

This report presents a thesis project conducted by two students at Mälardalens högskola. The project covers 15 points in industrial design and was conducted during April to June 2014. The principal of the thesis works at Plastic Produkter. The assignment was to develop equipment for an effective way to dose, mix silicon, fill a special designed plastic bag and then seal it. The bag is then formed into a breast model.When a customer for various reasons decides to do a breast augmentation or a breast reconstruction, there may be doubt or uncertainty about the result.

Den svenska arbetarrörelsens utmaningar och visioner - En undersökning av synen på kollektivet i LO- Tidningen 1991-2005

In this essay I have studied the Swedish Working Class whose part of LO.Ideological texts in LO- Magazines is used to quote texts by collective orindividual terms. Method and theory material show high level of solidarity andequality while theory shows higher level of individualism and autonomy. Myresearch is closer to Boréus than Blocks. Politics taking under the 1980: s apowerful right turns holding a steady course through my material.The question in the essay is: What vision on the collective shows in theLO- Magazine in a time during individualization? Answer to this question is thatthe collective unofficially through LO: s: staff on central level tries to showstrength and unity with terms like solidarity and equality between the sexes.

Jesu Kristi sinnelag : om konsensusmodellen i Kyrkornas Världsråd

This essay examines the using of consensus method for decision making within the World Council of Churches (WCC) and the process that led to the decision to adopt its usage. The main question of my essay is why the method was introduced to the WCC and what motives lay behind its introduction. Other questions are how the consensus method works; both in theory and in practice, and what the predecessors and prototypes for the method are.The consensus method belongs to a broad Christian tradition of spiritual discernment and spiritual decision making. The New Testament, in particular Acts, gives examples of decision making in the early church which show that discerning God's will was considered essential. However the most influential model for the consensus method have been the decision making process of the Religious Society of Friends or Quakers, and also the consensus model of the Uniting Church in Australia.

Framgångsrik Implementation av Lean : Förbättrade möjligheter med implementationsmodell

Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.

Samlande vs. tillgängliggörande : En jämförelse mellan två förvärvsmodeller på akademiska bibliotek

The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.

Utomhusbruk. Produkter formgivna för utomhusvistelser

My thesis was based on studying what really happens when Swedes move their beloved kitchen outdoors.?What kind of problems andpossibilities appears in this enviroment? First, I unbiassed examined the traditional kitchen in general to get a better view of how an outdoorkitchen could function in a country that have diffrent seasons. I intervjued an interior designer specialized in kitchenplanning to get abetter view. One thing that came up was that the experince of beeing outdoor sometimes puts functionality aside. I located different needs inthe outdoor kitchen enviroment and decided to work futher with one of them, outdoor lightning.The result became a 3d digital model of an outdoor lamp that creates both functionallight and moodlight.

Skapande av organisationskunskap i små, unga forskningsintensiva företag : En studie av tre företag i Uppsala

Because of among other things the globalization and a focus on core competencies knowledge has become very important for the companies of today, especially for research-intensive companies. The problem is that the companies become more sensitive to how knowledge is created and spread, that is, how organizational knowledge is created. Especially sensitive are companies who are small, young and research-intensive. The purpose with this thesis is to explore how organizational knowledge is created in small, young and research intensive companies.The theory is based on a five-phase model of organizational knowledge creation and four modes of knowledge conversion described by Nonaka and Takeuchi (1995). These concepts constitute the foundation of the analytical model used in the thesis.The study is carried out by qualitative, highly structured interviews with low standardization.

"Hur skall detta ske? Jag har ju aldrig haft någon man." : Hur feministiskt exegetisk litteratur bidragit till förståelsen av Luk 1:26-38 åren 1977-2012

This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.

An assessment of public procurement of timber buildings : a multi-level perspective of change dynamics within the Swedish construction sector

The construction and use of buildings in the EU accounts for half of the EU?s extracted materials and energy consumptions, and a third of greenhouse gas emissions. In the past decade, the construction sector has responded to such concerns by focusing on post production energy efficiency. However, new findings indicate that upstream construction processes influence emissions significantly ? necessitating a shift in focus to include material choices and building processes.

Integrerade folk- och skolbibliotek. En studie av två tänkbara organisationer.

The aim of this master's degree dissertation is to compile examples of different ways of planning, implementing and following up the organisation of two integrated libraries, which serve both the general public and the school. In order to respond to this, we formulated the all-embracing question: How best can the integration of libraries for schools and the general public be planned, implemented and followed up? This formulation gave rise to four further questions. In order to answer these questions, the problem formulated and our basic aim, we have studied the relevant literature on school libraries, libraries for the general public, and integrated libraries. These sources comprise official reports on this theme, dissertations, and more topical articles.
