Framtagning av beräkningshjälpmedel för tvärkraftbelastade förband med förbindare av metall.

The governing set of regulations for structural engineering in Sweden used to be Boverket, BKR. However in the beginning of the 21st century a changeover to new regulations, the Eurocodes, started.The transition was completed in year 2011 when the Eurocodes became the mandatory design work policy for all countries within the European Union. The Eurocodes were implemented to simplify and remove potential barriers to trade that may exist when countries have different design rules.  Since the changeover it has been important for all construction companies to update their knowledge base and their design software.When comparing the two calculation processes they seem similar, but there are a couple of differences worth noting.  With the new regulations, engineers will find that the process when designing joints in timber structures has changed.  What used to be a fairly easy and straight forward calculation procedure has now become tedious and time consuming.The objective of this degree project is to present a product, a dimensioning tool that will help structural engineers when computing lateral load carrying joints in timber structures.The degree project is made up of two parts where the first part is the written report describing the background and theory behind load carrying computations. The second part of the project is the actual dimensioning tool which includes several worksheets in Microsoft Excel. The program treats single and double shear connections of the following:Nail jointsScrew jointsSteel plates (thick and thin types) The user can edit the following parameters:Type of plate/ number of shearsStrength class of timber membersMember and plate sizeType of fastenerDiameter of fastenerLength of fastenerYield moment of fastenerkmod and partial factors for design load carrying capacityThe dimensioning tool was created and developed in collaboration with structural engineers at the company Byggteknik AB.

Vad motiverar ungdomar till att börja idrotta och vad är det som hindrar dem? : en intervjustudie om skillnader och likheter mellan svenska ungdomar och invandrarungdomar

Föreningsidrotten ökar men fortfarande är det många ungdomar som inte är tillräckligt fysiskt aktiva. Många undersökningar har gjorts angående motivation hos aktiva idrottare, men forskningen kring vad det är som motiverar ungdomar att börja idrotta är inte alls lika stor. Syftet med denna studie var att undersöka vilka motivationsfaktorer som skulle få ungdomar att börja idrotta och vad det är som hindrar dem, samt se vilka skillnader och likheter det fanns mellan svenska ungdomars och invandrarungdomars svar. Genom att undersöka vad som skulle få ungdomar att börja idrotta och vad det är som hindrar dem, skulle detta kunna hjälpa idrottsföreningar i hur de ska rekrytera nya medlemmar. Det är också viktigt att undersöka om det är någon skillnad mellan svenska ungdomars och invandrarungdomars motivationsfaktorer och hinder.

Medling i dispositiva tvistemål : En kritisk utvärdering av det svenska systemet

This paper is a critical evaluation of the Swedish system with special mediation. The district court has the opportunity, in cases that are amenable to out-of-court settlements, to refer the dispute to special mediation. However, this is extremely rare, even though the legislature expressed a desire to increase the use of alternative dispute resolution. In 2011, a series of measures were taken to increase the use of mediation and strengthen mediation attractiveness. What effect can be inferred from these actions today, over three years after their introduction? This study analyses the main reasons offered for why mediation is not used more, and what should be done to increase the use of mediation.

Bil- och järnvägstrafikens inverkan på inomhusmiljön med avseende på ljud och luft : - I planerade bostäder på Haga

NCC has given us a commission to investigate a planned housing area in Haga, Karlstad, situated close to the traffic route Hagaleden and the railway. The housing area consists of one hundred apartments in five different houses. The houses are linked to each other by balconies with glass panels. A long carport is situated between Hagaleden and the housing area to absorb part of the noise from the road. The design of the housing area is creating a silent backyard.

Kommunikation i en dynamisk miljö : En studie av närhetspar i beställningssekvenser vid släckningsarbetet i C3Fire

Det är viktigt med ett effektivt samarbete och en välfungerande kommunikation i dynamiska miljöer, till exempel vid släckningsarbetet av en brand. Bristande kommunikation i en sådan miljö skulle kunna få förödande konsekvenser.Denna uppsats bygger på material från studien ?Bridging Cultural Barriers to Collaborative Decision Making in On-Site Operations Coordination Centers?, där 32 svenskar samarbetade i olika lagkonstellationer med att släcka simulerade eldar i mikrovärlden C3Fire.Kommunikationsteorier visar på att personer samtalar med varandra efter en viss struktur; deras yttranden tenderar att komma i par, så kallade närhetspar. Denna studie syftade till att undersöka närhetspar i beställningssekvenser, i form av en beställning av vatten och/eller bränsle följd av en bekräftelse. Till sin hjälp hade försöksdeltagarna en datorskärm med en karta samt tillgång till ett e-postverktyg för att kommunicera inom laget.

Stockholms Energiframtid : En backcastingstudie för ett fossilbränslefritt Stockholms län 2050

This study concerns the energy future of the county of Stockholm up until 2050 and describes how the energy consumption can be compared to today with the use of scenario methodology. Within energy future studies the backcasting approach is well known and has been put to use in this study. Due to the characteristics of backcasting the study is self-fulfilling, i.e. the future energy scenarios presented in this study satisfy the targets set up in this study. In the light of what may be the largest challenge of our time ? the climate change - the aim of this study is to describe how the energy consumption in a fossil fuel free Stockholm county in the year of 2050 may be.

Lantbrukaren som energiproducent : en fallstudie i energisatsningar inom lantbruket

The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production. Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy. The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.

Nyckeln till arkiven : En kritisk diskursanalytisk studie om interoperabilitet och kollektivt minne

In the democratic process, of discussion and decision making, there is a need of reliable and authentic information. Archives are authentic and reliable information and also provides long term accessibility. But the public archives potential isn´t utilized enough at a societal level. The public archives are organized in a decentralised manner, and there are no common accesspoint at a national level. In the thesis this issue of accessibility and use at a societal level, is discussed in terms of collective memory.

Hållbar utveckling genom miljöbaserad offentlig upphandling? Miljökriterier i utvärdering av det ekonomiskt mest fördelaktiga anbudet

SummaryEurope?s public authorities are influential consumers. If they spend their money on greener products and services they can make an important contribution to the work towards a sustainable development. Green public procurement can thereby significantly improve the take-up of new environmental technologies. Through the effects of economies of scale, production costs be lowered and better equip us to fight environmental problems.

Framtagning av nyckeltal som indikerar kvalitetsbristkostnader : Development of key performance indicators revealing the cost of poor quality

Since the 1980s, companies have taken a larger interest in quality and it´s economic impact within the company. Having the knowledge that it´s not quality that costs money, but it´s rather the lack of quality. The work immerses itself in the field of cost of poor quality and the development of key performance indicators.The thesis is performed at Bufab Holding in Värnamo. Bufab Holding is a trading company which mainly buys and sells C-parts. C-parts include fasteners, other small metal-, rubber- or plastic parts such as wires, springs and electronic fasteners.The aim of this thesis was to make a survey of the cost of poor quality and to find key performance indicators (KPI) for cost of poor quality that can be continuously monitored.

Media advertising in Europe - The issue of standardisation from both the business and legal perspective

It is clear that media advertising is one of the crucial marketing tools for companies in order to promote their products and services. As we are moving towards more and more economic integration, both on a regional and global scale, the question about standardisation of media advertising has become increasingly important and is nowadays subject to discussion in most international companies. This thesis deals with the issue of standardisation in a region where the process of political, legal and especially economic integration is taking its course, but where cultural and linguistic diversity is still a remaining fact: Europe. The aim of this thesis was to investigate the potential gains from a standardised advertising approach but also to identify its limitations. Especially on a market place like Europe, with its diverse cultural and linguistic background, a fully standardised approach might be difficult to implement.

Utilizing the potential resources of elderly people : An interview study about the potential resources of elderly and young (40+) people, what those resources consists of and how they can be defined.

The overall purpose of this master essay is to investigate whether there is an interest among people near retirement to contribute with their knowledge and experience after they reach the defined retirement age. Furthermore, I would like to investigate if they want to continue with their old jobs, full time/part time or to do something else, which is beneficial to the society. I also want to find out how the older people view themselves to continuing to work. Also which types of social and structural barriers that might exist for them and why. The aim is also to investigate what types of knowledge and experience they believe could be used in the future community.

Interaktiva tavlor -Bara att införskaffa och sätta igång, eller? : En undersökning om vilka faktorer som påverkar införande och användande av interaktiva tavlor i klassrummet

Syftet med denna undersökning har varit att utifrån pedagogernas erfarenheter undersöka vilka faktorer som bidrar till alternativt hindrar att interaktiva tavlor används utifrån sin interaktiva potential i klassrummet - vilka påverkansfaktorer kan urskiljas för införande och användande av interaktiva tavlor i klassrummet? Undersökningen har även belyst motiven för satsningarna, användningen av den interaktiva tavlan i relation till erbjudandet om interaktivitet samt hur olika faktorer påverkar integreringen av tavlan i klassrummet. Undersökningen baseras på litteraturstudie, en mindre enkätundersökning samt ett par kompletterande observationer av klassrumspraktik.Respondenternas skolor har utifrån min tolkning valt att satsa på interaktiva tavlor utifrån arbetslivsaspekter och/eller demokratiaspekter snarare än inlärningsaspekter. Organisationerna har påverkats av omgivningens krav. De faktorer som lyfts fram i undersökningen utgår dels från lärarens kompetens, värderingar och intressen, dels till den praktik där individen agerar och dess egenskaper, krav och möjligheter.

Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.
