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.
Matematik och modersmål : Pedagogers syn på modersmålets betydelse för flerspråkiga elevers matematiska förståelse
This research is about how the educators view the best way to help multilingual students develop their understanding for mathematics. The aim of the study is to identify the different aspects from the teacher?s point of view of this new approach of teaching: what are the limitations versus the opportunities? The study is limited to a multicultural school in Stockholm and to the experience of a few class teachers and mother tongue teachers.A qualitative approach was used and the interview was selected as the method to collect the data. Three class teachers as well as three mother tongue teachers were interviewed about their experiences. The interviews were recorded and transcribed word by word.There have been discussions about the skills in mathematics in multilingual speaking students, and that their greatest obstacle of understanding mathematics is that they are being taught in another language than their own mother tongue.
Universitetsstudenters kostvanor : En tvärsnittsstudie om en grupp universitetstudenters upplevda kostvanor och kunskap i ämnet samt hur de upplever hälsotrenden.
Background:Studies show that when nurses are experiencing problems in the care of non-Swedish speaking patients, it is often due to obstacles in the communication. Studies also show that a prerequisite for adequate care is that there is a basis for a direct communication. Nurses perceive interpreters as an important link to the patient when they do not share a mutual language, the nurses perceive interpreters as a bridge in the conversation.Aim:The purpose of the study is to describe nurses' experiences of the quality of assessments done with the help of an interpreter.Method:The study was conducted through interviews with ten nurses, working at psychiatric clinics. Qualitative content analysis was used for the analysis, which resulted in five categories.Results:The analysis resulted in one theme: "it´s the interpreter who tells me and have not the feeling that the patient has" and five categories: "shades of the language", "conversation structure", "the interpreter's competence", "interpreting implementing" and "the interpreter's gender and origin". The nurses experience working with interpreters as a challenge.
Antiestetik - En studie kring musiksmak, värderingar och sociala strukturer inom hardcorescenen
Through participant observation in a local promoter group of hardcore punk shows inGothenburg and qualitative interviews with its members I have investigated links between taste in music, values and social structures in the hardcore punk scene. The theoretical framework of this essay is built upon the concept of subcultural capital, which is adapted from Pierre Bourdieu and developed by Sarah Thornton and Keith Kahn-Harris. The result shows how members among the hardcore punk scene create and preserve distinction towards others, while the distinction becomes important benchmarks for including and excluding practices in the scene..
Produktivitetsstudie Brobyggnad
The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.
Byggnadens andra skepnad : En anpassning för att möta samhällets behov och krav
Population growth leads to an increased need for new buildings, both residential and commercial. The regulations of structural design also changes with time. From a sustainable community perspective it may be profitable if existing buildings, that no longer performs their original function, are reconditioned. Knowledge and understanding of the surroundings of the residence must be available. Regulations regarding accessibility to all has increased.
Miljö- och samhällsekonomisk analys av behandling av biologiskt avfall
Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.
Social konflikt: en sociologisk studie av konflikten på Nordirland
Denna uppsats tar upp ämnet social konflikt i samband med Nordirlandskonflikten. Syftet med uppsatsen är att undersöka huruvida social konflikt kan verka främjande för samhället, samt att titta på de orsaker som gör att konflikten på Nordirland vidmakthålls. Detta har utförts genom en litteraturstudie av teorier utvecklade av Coser, Simmel och Merton.Slutsatser jag har dragit utifrån denna studie är bland annat att social konflikt i detta fall, parallellt med de nedbrytande faktorerna, också kan verka för en gynnande samhällsutveckling på vissa områden..
Känslan i bilden : Sociala taggars användbarhet vid bildsökning i Flickr
Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions.
När Imperiet Skakade : En postkolonial diskursanalys på The Sydney Morning Herald under åren 1947-1950 i relation till Indiens självständighet
This paper aims to demonstrate how the imperial attitude of the British Empire not onlycirculated within the British Isles, but also to and within the colonies, namely Australiain this case. It also shows how the discourse in an australian newspaper, The SydneyMorning Herald, might affect the people reading it and how thoughts about "the other"is reproduced in the media. The years 1947-1950 has been chosen because those werethe years of the Dominion of India, when India first became independent from theBritish Empire, to the formation of the Republic of India in 1950.All this is done by using postcolonial theory and discourse analytic method hand inhand to de-veil the structures of Empire within the media..
Konstruktion och utvärdering av Current Conveyors
Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.

Kompetens som lockbete : En studie i lokala och centrala biblioteksföreträdares syn på marknadsföring av bibliotekariekompetens gentemot lokala politiker
The aim of this study is to explore if and how library managers market their competence in communication with local politicians. It is also our aim to find a definition of the competence of librarians. The report identifies and describes problems and possibilitieswith marketing of competence to politicians on the basis of one Swedish municipality's library managers. In order to fulfil this aim we have used a literature study on marketing, competence, the political process and the librarian profession. We have alsocarried out an empirical study where we interviewed ten library managers in onemunicipality, seven politicians in the same municipality and ten representatives for central professional organisations mainly in Sweden.The results are that most library managers don't market their competence because they don?t believe in marketing competence.
"I will go now to my pyre" : Isaks bindande läst genom J.R.R. Tolkiens The Lord of the Rings
This paper investigates the science fiction novels of Swedish crime writer Per Wahlöö, most famous for his collaboration with his writing partner Maj Sjöwall on the ten Martin Beck mysteries. During two important years, 1964 and 1968, Wahlöö wrote the novels Murder On the 31st Floor and The Steel Spring, set in a near future land ruled by a social fascist power structure where political opposition is eradicated. The pretexted notion of this paper is that these novels consists of extensive quantities of criticism against the Swedish welfare state and the monopoly-capitalistic Swedish press during the sixties. Through the lens of science fiction theory and the notion of the novels as historical sources this paper concludes that PerWahlöö´s science fiction becomes a bridge between the classic Swedish detective novel and the new social critic crime fiction in the style of Sjöwall-Wahlöö and others. The novels are also representations of the historical process in the mid-sixties during the radical turn: the sci-fi novels as social criticism of the contemporary society ? an utopian flare.
