En granskning av Utbildningsradions program ur ett mångfaldsperspektiv : En kvantitativ innehållsanalys av 50 program för årskurser 0-3

Utbildningsradion (Swedish Educational Broadcasting Company) is a public service broadcaster with a mandate to produce and distribute educational programmes. 80% of Swedish teachers use its products either during lessons or for professional development. Utbildningsradion?s guidelines, set by the Swedish parliament and government, state that the company?s programmes should meet the interests of the country?s whole population, regardless of their background.The purpose of this study is to examine how Utbildningsradion?s products that are intended to be used in a classroom setting for ages 6 to 9 represent the variety of children that live in Sweden and thus reflect the aforementioned guidelines. The main focus of this research project was further defined to only include the company?s television programmes produced in Sweden between 2006 and 2011 that do not have social issues as the main subject.50 programmes were analyzed using quantitative content analysis and the following results were further interpreted using mainly Kydd?s and Snead?s models for discussing representation.

Termomekanisk utmattning av Sanicro 25 : Materialmodellering med finita elementmetoden

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.

Gruppverksamhet för barn till missbrukare : en jämförande studie av två gruppmodeller

In Sweden approximately ten percent of all children grows up in a family where at least one parent is having an alcohol related addiction. Since 1998 the development of group activities for children in this situation has been immense. The aim of group activities is to break the child's isolation and make them feel that they are not lonely in their experiences, give them knowledge about addiction and relive the pressure of guilt and responsibility.In a comparative study we examined studied how two different group activity models one with the conception of illness and one without, use the children's network to support the group process. The aim was also to find each models definition of the "normal family", since we understood the groupactivity as a part in the normalization process. We reached our aim through interviews with group leaders and by literature studies.

Höjdmodellering med laserdata : Studie av Kärsön, Ekerö med fokus på upplösning, datalagring samt programvara

The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.

Log Search : En form av datamining

This report examines the possibility of optimizing troubleshooting log files generated when constructing new Volvo trucks. Errors occur when CAD models are stored and managed by the versioning system PDMLink. By developing a new diagnostic tool, Log Search, the troubleshooting process is automated and thereby streamlines the current manual search..

Varför BIM?

Is the new technology always the best? This final project tries to determine if BIM is the melody of today, or if traditional 2D drawing is recommended. Perhaps a compromise is necessary, utilizing both methods.In order to answer this question, different views from the industry have been retrieved through reports, producers of software and users. The approach has consisted in building a 3D model of the school Råslättsskolan, house 01, along with interviews with people involved in the building process.When working in 2D it is hard to include the third dimension, mistakes are done and collisions happen that must be corrected, in most cases at the construction site. BIM is an incredible help since the model allows you to detect collisions and correct them.

Information per sträcka

Jag har låtit min yttre miljö vara en stark tongivare och låtit det förenas med mitt verk. Det mesta av mitt arbete har jag utfört i min egen verkstad. Det är en ateljé utformad runt en traditionellguldsmedsverkstad med de verktyg och material som hör till. Där har jag omgivit mig med bilder, material och föremål som intresserar mig.Resan och förflyttandet mellan HDK och min verkstad var min utgångspunkt. Det har jag dokumenterat och uttryckt i olika material..

Regional demokrati : om en framtida regional samhällsorganisation i Östergötland

The purpose of this essay is to present, from a theoretical framwork about regional democracy, possible methods to handle the regional democratic problems in Östergötland in Sweden and to investigate the opinion of the political parties regarding this issue. Both the national and the local/regional level are investigated. The contents of the essay is based on literature studies and interviews of politicians in Östergötland. Regional democratic problems that is discussed are the political responsibility and the power distribution between the political actors on the regional level. A solution of the problem could be to organize the regional society structure in accordance with one of the following organization models"Statligt regionalt ansvar","Kommuner i samverkan"or"Regionalt folkstyre".

Automatisk Identifiering av Inandningspauser i Spontant Tal - ett HMM/ANN-hybridsystem i Matlab

?Matteboken, det är där man lär sig?eller? : En undersökning av lärares och elevers inställning till användandet av laborativt material i förskoleklassens matematikundervisning

Syftet med vår undersökning var att ta reda på hur läraren och eleverna ser på användandet av laborativt material i förskoleklassens matematikundervisning. Undersökningen genomfördes med hjälp av observationer och intervjuer av tre lärare och nio elever i samma kommun. Resultatet visar att lärarna och eleverna ser olika på användandet av laborativt material. Lärarna förhåller sig positiva till användandet och menar att de alltid har stöd av laborativt material i undervisningen. Eleverna däremot visar en osäkerhet kring syftet med användandet av materialen och har svårt att se det matematiska innehållet..

Icke-linjära modelleringsteknikerav förspänd betongkonstruktion : Reaktorinneslutningen på Forsmark 3

A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization.

En studie om vad tre klasslärare anser om laborativt arbetssätt i matematik

Syftet med detta examensarbete var att undersöka vad tre klasslärare för årskurs 1-3 anser om laborativt material i matematikundervisningen och hur de själva arbetar med detta i sin egen matematikundervisning. Detta undersöktes med hjälp av en kvalitativ studie med intervjuer och observationer. Observationerna användes för att se om det som lärarna ansåg om laborativt material speglades i deras undervisning. Med intervjuerna kunde vi ta reda på vad lärarna ansåg att det kan finnas för möjligheter och hinder med användandet av laborativt material i matematikundervisningen. Resultatet visar att lärarna överlag är positiva till användandet av laborativt material.

Att välja perspektiv : "Arkitektur i Sverige - Funktion, konstruktion och estetik genom tiderna".

This essay tries to show how The Swedish Museum of Architecture, Stockholm, with the exibition Architecture in Sweden - Function, Design and Aesthetic through the Ages, presents and represents architecture. It is stated that this is done in a multi-perspectival, multimedial fashion, with the aid of, for example, photography, models and mixed material surrounding the wide concept of ?architecture?. One chapter discusses the relationships between the exhibition on site, the exhibition catalog and the museum´s website. Another chapter argues that there can be no essential or perfect representation of architecture, although this utopian wish most certainly exists even today.

1600-talets urvalsprocesser för tryckta verk : Produktion och distribution av böcker och dissertationer i Stockholm och Uppsala

During the 17th century the production and distribution of printed works increased in Stockholm and Uppsala. However, all works that the publisher wanted to print, did not reach the reader. This thesis aimed to show when, where and how printed books and dissertations did not reach the reader. To achieve this aim, aspects of several well known models showing systems of book production and distribution were combined and adapted to suit Swedish conditions in the 17th century. This combined model focused on processes of selection and was presented and used as a theoretical approach.

Handbok för växtinsamlare : med erfarenheter från sex nutida svenska experter

What makes a Swede betake himself into the Chinese wilderness? How does the Rio Convention influence a plant collector? And who will crack the nut positioned 12 meters up in the crown of a tree? There are many secrets behind the act of collecting plants. In many regards, the documentation of the collection of plants for a Swedish purpose has been unsatisfactory. The focus of the publications is on what plant species that have been found rather than information on how these plants have been collected. Only few results of experimental cultivation are available. There is no doubt that there exists knowledge that has not been publicised yet.
