Modell för dimensionering av AGV-system inom tung industri

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

Välbefinnande och Kognitiv Prestation : En experimentell studie om positiv sinnesstämning främjar kreativitet och flexibelt tänkande

The purpose of the study was to investigate, through an experiment, if positive mood promotes creativity and flexible thinking. Participants were a total of 93 college students. The main hypothesis was that subjects induced with positive mood would perform better than subjects induced with negative mood, at a test reflecting creativity. To further explore the implications of priming (subliminal manipulated moods), a neutral control group was included. The cognitive test used in the study was Duncker´s The Candle Problem, a test which aims to get the subjects to apply flexible and creative thinking.

FPGA baserad PWM-styrning av BLDC-motorer

This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

Barn som vistas på kvinnohus : En fördjupning av Oasenmodellen som arbetsmetod

At the Women?s House in Örebro, a children?s project has started where the work method ?Oasen? [Oasis] model has been developed by two children?s educationists. The aim of this study is, with the ?Oasen? model as a starting point, to deepen the knowledge of (1) how to meet children?s central needs while staying at a Women?s House and (2) what the ?Oasen? model may contribute to the children. The theoretical framework consists of a cognitive approach to the progress of children experiencing domestic violence and a presentation of conceptions concerning children?s needs.

Kunskap i biologi hos invandrarelever : En undersökning på en grundskola i Västra Götaland

The main purpose of this study was to examine the knowledge in biology by immigrant pupils. My investigation is based on the pupil and I have focused on positive and negative factors that affect their performance in biology.The study is based on marks in year 2006/2007, a survey and interviews made with four immigrant pupils at a compulsory school in Västra Götaland.The study indicates that the result in biology of immigrant pupils is lower compared to Swedish.Difficulties in language, the commitments by their parents and their surroundings are the main factors that affect their results negative..

  Olika betyg med hänsyn till program, elevernas och lärarnas kön? :   En undersökning av betygsmedelvärde i Svenska A, Matematik A och Engelska A i två olika gymnasieprogram och städer.

I have with this thesis sought to understand how chick lit could be useful in the classroom in the teaching of Swedish B-course in high school. Based on the model of critical literacy I am arguing that this genre would help to meet the objectives of the policy documents which, among other things, are to critically examine and analyze various types of texts.I have found that some of these texts could be used for analyzing and critically examine the ideological dimensions of texts and cultural heritage by the model of critical literacy, and also as a counterweight to the more traditional teaching of the canonical literature as a literary historical stuff that students should learn. I have also wanted to create a basis for discussions about literature in the classroom based on the chick lit genre. To do this I have, based on three themes and questions from the model of critical literacy, tried to focus on issues that might emerge from the ideological analysis and critical review. The model aims to deconstruct norms of society, and in the work of chick lit, I wanted to show how you could deconstruct norms around gender..

Att vårda patienter i ett sent palliativt skede : Ur ett sjuksköterskeperspektiv

Background: Nurses´daily has to face death and dying in their work with patients in a palliative state.  This means both emotionell and workrelated challenges. However nurses in this context are not experiencing more stress then others.Aim: The aim is to describe nurses´experiences of caring for patients in a palliative state.Method: A litterature review based on ten qualitative articles published between 2006- 2012. To collect data we used the databases Cinahl, PubMed, Nursing Allied Health Source and Medline. We worked with Fribergs (2006) model ?Contribute to evidensbased care with a base in analyses of qualitative science? in the analysis.Result: Four main themes were identified; The meaning of the nurses´ spirituality in the care, Why the nurse choose to work in this field, To be certain in the professional role and The meaning of the caring relationship.

Resursskolans betydelse för eleverna

Students who regularly cause trouble in school, how can they learn anything? That is what we asked ourselves after having visited a special school for ?troublesome students? (in Swedish resursskola). Our main purpose has been to find out how these students have experienced the help they have been given in those schools.We have interviewed students, parents and a social worker in order to find out if the alternative pedagogical methods used by those schools give the students better opportunities to perform their schoolwork. The interviews have been made two or three years after the end of their studies in compulsory school (grade 9). We have used a qualitative method with semi structured interviews and also an evaluation model.

Välfärdseffekter av ett frihandelsavtal : en ekonomisk analys av ett EPA-avtal mellan EU och ESA

The EU has had a special agreement with their former colonies in Africa, the Caribbean and the Pacific Islands, the ACP-countries, for almost 30 years. This has granted the ACPs with preferences on the Europen market, which have been excluded from other countries. The agreement is now beeing re-negotiated to make it more in terms with the rule of the WTO?s most favoured nation-principle. The new agreement will differ from the present one as it will be a mutual free trade agreement where the ACP countries will open their markets to the EU as much as the EU opens up it?s market to them.

"Nu är det slut på sossepjalleriet och pisshumanismen" : Om kravet på motprestationer inom socialtjänsten

The purpose of this study was to determine if and how the city district of Södra Innerstaden in Malmö, by using the Skärholms model, demand their client to reciprocate. The first problem set was to see how the demand was shown in the social service act from year 1998. From there the motives behind the introduction of the Skärholms model in city district of Södra Innerstaden were researched and also if there were a demand on reciprocity in city district of Södra Innerstaden public administration. The study was conducted in an exploratory way. The method used was to describe the idea behind Skärholms model after examining documents from the public administration.

Betydelsen av att samverka : En studie av det interorganisatoriska samarbetet kring demensvården i Halland

The purpose of our study is to interpret and understand the collaborative process around a regional model that is based on state developed guidelines for people with dementia. We have chosen to focus on the importance of interaction and have therefore interviewed participants in the project's steering committee. This group participates in efforts to develop a model for dementia care in Halland.The project work in Halland, to develop a joint model for people with dementia and their families was initiated in the spring of 2011 and is due to finish at the end of 2012. The Halland model has been named ?Annas led? and is about Anna and her husband Lars and living with dementia.

Kan vi prata om det? Deliberativ demokrati, mångfald och politisk kamp

In recent years the liberal representative democracy has been subject of a substantial critique because of its inability to accommodate difference and createa genuinely democratic political process. One such critique comes from the theory of deliberative democracy. Supporters of deliberative democracy try to promote a model of democracy that take its vantage point in free and equal deliberationbetween all relevant actors in a political community. This model has with some success opposed the aggregative model of democracy, and in important ways turned the attention to the potential of deliberative processes.However, the deliberative model is still somewhat underdeveloped when it comes to issues of diversity and difference. This essay deals with such deficiencies by analysing deliberative democracy in the light of the critiquelaunched by difference- and radical democrats.

Bokbloggen i de litterära kretsloppen : En litteratursociologisk analys

This thesis explores the position of book blogs in the literary system through Robert Escarpit's socio-literary model of the book market. Simultaneously the thesis serves as a test for Escarpit's theory: by actively applying his theory and model to a very new and contemporary actor on the book market I hoped to reach or confirm new insights into the usefulness and validity of Escarpit's work for contemporary socio-literary studies.Three book blogs were selected for the analysis and interviews were carried out with the authors. The interview questions were formulated specifically for the purpose of extracting the kind of information necessary for an analysis using Escarpit?s theory. As a complement to the interviews, statistics on the type of books reviewed on the blogs were also compiled.

1-D Modellering av Piezoelektrisk Injektor

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Inventering av processvattenbalans : fastställande av fjärrvärmedistributionens läckage inom Vattenfall Värme Uppsala AB

Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult. Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed daily. The project is performed at Vattenfall´s district heating power plant in Uppsala. Information is gathered through discussions, drawings of the plant and guided tours of the plant.
