Lärande : En studie om ledarskapets påverkan på lärandet

In this essay I have studied how the kid?s school start are described in picture books. The studied questions are: How the school is described in these selected picture books; what feeling does the main character have into the school start; how the teachers are described in this selected picture books and how are the power relationship described in these selected picture books?The method I have chosen for this essay is a discourse analysis of seven selected picture books with the meaning of starting school. All books studied are written during the 1990 and forward.

Framställning av komponentbibliotek i autodesk Revit. Modellering av köks- och badrumskomponenter samt takstolar

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.

Legitimerade sjuksköterskors förhållningssätt till psykisk ohälsa : Med själen i fokus

Patients with mental illness experience dissatisfaction with their care due to lack of understanding and ignorance from the nurses. The nurses? approach might influence these patients' experience of their care. The purpose of the literature review was to describe nurses' approach in care of patients with mental illness. The literature review is based on an inductive approach and the result is based on 14 scientific papers, of which eight used a qualitative design and sex used a quantitative design.

Nätnyttomodellens fall och framtidens reglering av eltransmissionstariffer : Tidigare meningsskiljaktigheter samt undersökning av förutsättningar för framtida reglering

The main ambition of this degree project is to illustrate the fundamental problems of today?s electric tariff regulation and the usage of the analyzing tool; The Network Tariff Model. There is a further discussion of potential problems and clear improvements of the 2012 years proposed network tariff regulation. Interviews have been conducted with specific network companies and Energimarknadsinspektionen. The proposed regulation of 2012 is discussed from the government?s proposition.This paper clearly shows that the authority´s work has been conducted in a very unprofessional manner during the period of The Network Tariff Model.

Statushantering i Virtual Map med ledningssamordning i BIM

For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.

Värdelöst värdeskapande : En studie om co-destruction

The study proceeds from a phenomenom called co-creation. If value can be created, it is logic to asume that it also can be destroyed. This phenomenom has earlier not been applied to long-term relationships such as business to business. In a business relationship it is important to identify factors, that leads to co-destruction, to be able to prevent them from appering. The purpose of this study is to identify which factors leads towards co-destruction.The study have used theories from Echeverri & Skålén (2011) which has designed a model explaning the outcome of co-creation and co-destruction.

Busshållplatsers kapacitet : Utvärdering av tillämpbarhet av modell från Highway Capacity Manual 2000 med uinderlag från busstrafik i Stockholms innerstad

Stockholm is growing with almost two fully loaded SL-buses a day. One of the consequences that derive from this is the increase of public transport travelers who put the regionally governed public transport up to the test in terms of its capacity. The Transport administration in Stockholm County initiated 2015 a project with the purpose of simplifying the calculation of bus stop capacities. A hypothesis (set up by the Transport administration) based on that a model for calculation of bus stop capacities could be calibrated for Stockholm conditions is being researched in this bachelor?s essay.The study is implemented by self-collected traffic data from bus stops located in the Stockholm city center.

Analys av instyrning och rolldynamik

When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.

En studie av två invänjnings-modeller i förskolan. :  3-dagars och två-veckors modellerna 

I have made a research about two different methods for introducing small children to Nursery School/Kindergarten. I choose to do this as I have found very little about this in the literature we have studied during my education to become a pre-school teacher.This period in the life of very small children and their parents is a big change in their daily life. The more traditional way to start pre-school is to do it very gradually during two weeks, the two-week method. This means that the parents visit the pre-school together with their child for a very short time, about one hour the first day. After one week they leave their child with the staff for about an hour and at the end of that week they try to leave it full time (6-8 hours).

Från underhållning till motstånd. Om kvinnors läsning av Harry Potter-böckerna

The purpose of this study is to examine how women?s reading of the Harry Potter books can be understood on the basis of gender theory and reader-response criticism. The empirical data is gathered through qualitative interviews with six female Harry Potter readers between the age of 21 and 35, and is analyzed through several theories regarding gender and reading. The results show that the readers are critical towards many aspects of the books, especially when it comes to the stereotyped depiction of women and men. The books are said to reproduce the gender dichotomy, the gender hierarchy and the heteronormativity in society.

Analys av turbulensmodeller för CFD

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

På jakt efter den produkt som flytt - en studie om uppskjuten produktlansering och dess effekter

Many product launches are postponed today, however very little research regarding to customer responses to such events has been carried out. The purpose of this paper is to investigate how people react to a postponed product launch. An experimental study of responses to a postponed launch of a mobile phone, a mineral water and a music album is used to investigate customer reactions. The respondents exposed to the postponed launch showed a higher value of reactance. This reactance affects the attitude, purchase intention and perceived quality of the product in a negative way.

Riskfaktorer för förlossningsdepression samt förebyggande åtgärder ? En litteraturbaserad studie

Introduction: Approximately one in eight women suffer from postpartum depression, which can affect them for a period of weeks or even years. Postpartum depression does not only affect the mother, it also has a negative influence on the rest of the family. Postpartum depression can also lead to negative consequences for the development of the infant. It is an illness that is still considered a taboo, a fact that makes it hard to identify among women who are affected. Aim: The aim of the study was to examine cases where there is a connection between social economic status (SES) and the presence of postpartum depression.

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.
