In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

In this diploma work the approach of determining the required amount of reinforcement in slabs exposed to pure tension is processed, on behalf of Ramböll Uppsala. It is a well-known problem in the industry that there are uncertainties in the determining of the amount of crack reinforcement, especially for structures exposed to pure tension. Cracking caused during the time of dehydration in concrete slabs is the most common defect according to statistics made by CBI[1], which provides numbers as high as 35 % of all the defects caused on slabs are generated by cracks. Comparisons between Sweden's former national standard BBK 04, Building Regulations for concrete structures due to restrained forces of shrinkage, and the current European standard Eurocode 2 are carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed.

The purpose of this study was to build a database for point-bearing piles in dense noncohesive soil, predominantly moraine. Further, the database was analysed and areas with difficult geotechnical conditions was identified.The database includes for point-bearing piles driven to refusal in moraine. Piles with mainly shaft friction have been excluded. Only concrete piles have been included. Geographically the database covers almost all geotechnical conditions of Sweden.

Det här examensarbetet undersöker om ett anatomiskt system framtaget för att kategorisera ansiktsrörelser inom psykologisk forskning kan anpassas på en ansiktsrigg för att effektivare kunna framställa ansiktsanimation för datorspel. Rapporten beskriver varför Facial Action Coding System skapades, hur det används samt tar upp olika sammanhang som systemet tidigare använts för. Rapporten beskriver det praktiska arbetet för att konstruera en ansiktsrigg ämnat för datorspel och diskuterar skillnader mellan att rigga för datorspel och film. Examensarbetet beskriver klassiska användbarhetsprinciper och vad man bör tänka på när produkten skall bli så användningsbar som möjligt. Ett animationsverktyg baserat på FACS och de ?Action Units? som systemet innehåller har tagits fram för att genomföra undersökningen på animatörerna från min praktikplats på Starbreeze Studios AB.

AbstractConcrete foundation slabs are usually exposed to unilateral drying during the curing process. The unilateral drying causes an axial shrinkage and a concave curvature of the construction. The curvature results from the fact that the upper part of the slab is drying and shrinking faster than the lower part. This is called gradient shrinkage.A problem occurs when the slab is considered fully restrained by adjoining structural parts. The deformations caused by axial contraction due to the constant part of the shrinkage and the curvature caused by gradient shrinkage of the slab are then prevented by the fact that the slab is fully restrained.

The aim of this paper is to examine how the Swedish implementation of the new trafficking laws may differ from the original intention from the UN and EU and if they are substandard due to poorly conducted law implementation. Or if it might be a victim of political symbolism, to win support and votes for the politicians in power from the people, a ?hollow showpiece? only meant to be shown off. Trafficking is a relatively new phenomena and problem to be researched and discussed. This paper investigates the impact of the Palermo protocols international definition of the problem, the convention against organized crime presented by the European Union on the Swedish legal system and its action plan. A qualitative text analysis focusing on the discourse of the intentions behind the internationally presented legal documents and compared against the carrying out of said national objectives.

Betong är vårt vanligaste byggmaterial men cement står globalt sett för 5 % av CO2-emissionerna. Med detta som bakgrund så har CBI Betonginstitutet anordnat en tävling, där målet är att nå den högsta tryckhållfasthet i en resurssnål betong, med enbart 200 kg cement per m3. Syftet med denna rapport är att utvärdera tävlingen, vilket har utförts genom en omfattande litteraturstudie. En första analys av de olika betongrecepten medförde att olika grupperingar kunde urskiljas. Ur dessa fanns det tre stycken vars resultat var väldigt bra. ? Concrete Innovation Centre, som med ett lågt vct, stora mängder granulerad masugnsslagg (81 %) och lite silikastoft (5 %), uppnådde en tryckhållfasthet på 80 MPa vid 28 dygn och 95 MPa vid 56 dygn. ? CBI Stockholm, som genom användandet av ulltrafint filler och silikastoft (4,8 %), uppnådde en tryckhållfasthet på 84 MPa vid 28 dygn och 98 MPa vid 56 dygn. ? Thomas Concrete Group som genom att ersätta cementet med en medelmåttig mängd granulerad masugnsslagg (54 %), liten mängd flygaska (9 %), kalkfiller och silikastoft (5 %), uppnådde en tryckhållfasthet på 94 MPa vid 28 dygn och 98 MPa vid 56 dygn. Det finns således tre recept som vidare studier kan vara rättfärdigade på, de tre ovan nämnda. Det bör tilläggas att en imponerande tryckhållfasthet på nästan 100 MPa, kan uppnås i en betong med enbart 200 kg cement per m3. .

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

Tryckhållfasthetsutveckling hos broar. En studie av svenska broar byggda under 1900-talet.

Work, especially that in complex, dynamic workplaces, often requires subtle, local judgment with regard to timing of subtasks, relevance, importance, prioritization and so forth. Still, people in Nuclear Industry seem to think safety results from people just following procedures. In the wake of failure it can be tempting to introduce new procedures and an even stricter "rule following culture". None, or at least very little, attention is given to tacit knowledge and individual skills. I am aiming to highlight the inadequacy of putting too much trust in formalization and that reporting and trending of events will contribute to increased learning, an increased nuclear safety and an efficient operational experience.

AbstractAimThe aim of this study has been to survey the background of the youths in the selection group which participated in the Dream action day, to evaluate if the project succeeded and support the Swedish Ski Association with their recruiting process. The questions of issue have been: Which ethnical, demographical and economical backgrounds do the youths of the selection group have that participated in the Dream action day? Is there any common denominator among those who was drawn to continue? Do the youths want to contribute to expand the sport? Is Dream action Day a good way to reach out to the target group?MethodThrough a strategic selection made by the Swedish Ski Association 44 youths participated in a day during which they tried snowboard. They have been a part of our quantitative data collection and we have chosen six to interview. The interviews have been executed in form of semi structured interviews.ResultsThe results clearly show that few of the participants had any connection to the sport, neither from home nor from friends.

Declining union memberships are a fact in both Sweden and Finland. At the same time, the autonomous labour market parties and the high membership rates are the most significant factors for the two countries compared to Europe and the rest of the world. These two factors have in turn been developed and strengthened since the beginning of the twentieth century. By autonomous labour market parties I refer to the fact that the labour market parties themselves through collective bargaining are agreeing on the labour market conditions, without interference from the government.This paper is therefore taking it's stance in the question of what happens with the autonomous labour market parties when the membership rates are in decline. With this in mind, this paper describes the judicial development, the collective agreement and labour market structures, the legal consequences of collective agreements and the opportunities of industrial and sympathy action in both Sweden and Finland. The two countries' systems of labour law have caught some negative attention, hence two of the most discussed cases of recent years are given some attention as well. The collective judicial conditions are very similar in both Sweden and Finland regarding the labour market main actors' collaboration, the collective agreement structures and legal consequences and the opportunities of industrial and sympathy action.

When constructing an industrial- or hall building, the most common framework materials thatis used are wood, steel or concrete. Due to an assignment from Byggnadstekniska Byrån ABhas a document been created that makes it possible to investigate how the final costs is af-fected by gapes in between elements and which used foundation. And this with steel as thematerial. The purpose with this essay is to investigate which is the most well fitted materialwhen constructing an industrial- or hall building wood, steel or concrete. Information aboutthe different materials has been collected by litterateurs and by different internet pages.

The opinion of social workers towards their work with children and young persons wasstudied in this essay. Even their point of view with reference to the term the child?s bestinterest has being considered and special focus was laid on the social workers attitudestowards media coverage and its criticism towards their work. A qualitative approach was usedconsisted of six interviews. The theoretical frameworks were based on the theory aboutfreedom of action and the theory of social representations.

Benämningsförmågan av verb och substantiv kan påverkas på skilda sätt vid neurologisk skada eller sjukdom och idag finns inget normerat verbbenämningstest på svenska. Syftet med föreliggande studie var att översätta och ta fram normvärden för friska vuxna personer på Action Naming Test (ANT), samt att undersöka huruvida ålder, kön, utbildnings- och kognitionsnivå påverkar resultaten.Målorden i ANT översattes från engelska till svenska genom omvänd översättning och 120 personer i åldrarna 20-83 år testades med detta. För möjlighet att undersöka inverkande faktorer på resultaten samlades information om utbildningsnivå in och deltagarna testades även med Irregularly Spelled Words (ISW) och Wechsler Intelligence Scale for Children-III (WISC-III) Blockmönster.Resultaten visade att ålder, utbildning och kognition hade en inverkan på hur friska vuxna personer presterade på ANT. Yngre deltagare presterade signifikant bättre, liksom deltagare med hög utbildnings- och kognitionsnivå. Hänsyn bör tas till att anpassningar till svenska språket inte är fullständigt utförda, men då resultaten har ett stort underlag kan de ändå användas som normvärden vid testning av verbbenämningsförmåga hos personer med neurologisk skada eller sjukdom..
