Bors E23 - Framtagning av eldriven röravklippningsmaskin
Our Bachelor´s Thesis has been performed in co-operation with Bors Automation & Tool AB.Our task was to develop a servomotor powered tube cutting-machine with initial point fromtoday's hydraulic driven tube cutting machine Bors HYD 23. The purpose with the newconstruction was to achieve a more power-efficient tube cutting machine which could lowerthe power consumption, and also meet the market continued growing demand forenvironmental-conscious production.Bors Automation & Tool gave us relatively free hands in order to enable new thinking ideaswithout following their traditional constructional solutions.Our solution resulted in a construction based on a power source existing of a servomotordrivenrollerscrew, witch provides a more rational use of energy compared with the currentmethod.Bors Automation & Tool AB has decided to fabricate a prototype of Bors E 23 during theautumn of 2007, which they are planning to revile at the Tube 2008 exhibition in Düsseldorf,Germany.NOTE:Due to an agreement signed by the authors in the beginning of this project, no appendix is published at this time.If you want to wiew these documents, please contact the authors..
Automatisk bullerdosreglering i hörselskydd
På bullriga arbetsplatser använder personal ofta hörselskydd med inbyggda högtalare för att lyssna på exempelvis musik i underhållningssyfte. Om användaren lyssnar på höga ljudnivåer under långa perioder kan bullerskador uppstå i dennes öron. Enligt lagstiftning måste nivån därför begränsas i förebyggande syfte.Bullernivån är ett genomsnitt av de ljudnivåer användaren exponerats för under en arbetsdag. Användaren måste vila öronen om gränsvärdet för bullernivån nås.Om man utnyttjar att det är ett genomsnitt kan användaren tillåtas lyssna på en hög ljudnivå under en begränsad tid för att sedan sänka den. Det går att bevara både säkerheten och lyssningsupplevelsen om en sänkning införs långsamt.Detta arbete beskriver hur en algoritm till en digital signalprocessor kan konstrueras för att reglera ljudnivån.Målsättningen var att algoritmen skulle skydda användarens hörsel utan att försämra lyssningsupplevelsen, och utan att förbruka mer energi än nödvändigt.I algoritmen ingick en prediktor som predikterar mängden buller användaren riskerar att utsättas för, om denne fortsätter lyssna på samma nivå.Långsamma sänkningar av ljudnivån kan då utföras i tid innan gränsvärdet nås.Det visade sig att algoritmen endast behövde ett fåtal samplingar per sekund för att skatta och reglera ljudnivån tillräckligt precist, vilket reducerade energiförbrukningen.Resultatet visar möjligheten att kombinera målen för säkerhet, lyssningsupplevelse och energieffektivitet i hörselskydd.Algoritmen implementerades inte på ett skarpt system.Den hade enbart tillgång till ljudsignalen användaren ämnade lyssna på i underhållningssyfte..
Energiåtgång under tillverkning och produktion av byggnadskomponenter
This diploma work addresses the question of how much energy is spent whenmanufacturing the components of a building as well as of how much energy is used inthe production of a building. The object of the studies is BioCentrum at the SwedishUniversity of Agricultural Sciences in Ultuna just outside the city of Uppsala. The aimof the work was to investigate how much energy was consumed when manufacturingand production in relation to the management, how many years the production wasrepresented. It was also a study in how mature the construction industry is to answerhow much energy was consumed in manufacturing.In order to get these answers a question form was developed and sent to thesuppliers to BioCentrum. In this form they were to respond to the quantity suppliedto BioCentrum and the amount of energy was spent when manufacturing thecomponents.

Stress, kreativitet och problemlösning : En kvalitativ studie i hur vi lo?ser problem under stress och vad detta kan inneba?ra fo?r designprocessen
Problem solving is a big part of design, however a lot of emphasis is put on creativity in research related to the effects of stress. Research has shown that the amount of stress we feel affects idea generation. Stress may also affect the ability to solve problems, however the researchers don?t seem to agree about what the effect of stress actually does.The study was made through experimental sessions where the respondents were asked to solve 4 matchstick puzzles of similar difficulty. Depending on their outcome they experienced more or less stress.
?Hon får skylla sig själv? : En undersökning om attityder på svenska internetforum avseende våldtäkt mot kvinnor
The purpose of this study was to highlight how women who have been victims of rape are described in discussion forums on the Internet and how the view obtained is affected by victim and gender constructions. By observing several discussion threads on Swedish internet forums, we have been able to explore how discussions and attitudes are made about women who are victims of rape and which characteristics are assigned females. This study analyzes these attitudes from a gender construction theory and a victim construction theory. Through this analysis, we wanted to gain a deeper understanding of attitudes about female rape victims and if the attitudes are rooted in victim and gender constructions. This study shows that women are often assigned responsibility to a rape if she put herself at risk and if she is assigned negative attributes such as promiscuous, as a liar or if she drinks too much alcohol.
En diskursanalys av föreställningar kring vulvavestibulit hos tre intervjuade kvinnor med vulvavestibulit
In the paper three women with vulvar vestibulitis (long-term pain condition during sexual intercourse) were interviewed to find which conceptions the women experience exist about vestibulitis and how the women they self feel about the condition. Furthermore it was examined if and how the construction of vulvar vestibulitis affects the identity of the women. The method used was half-structured interviews with interview guide. Foucault's discourse analysis was used to analyse the interviews. Several constructions of vestibulitis were revealed from the interviews.

När mormors resa blir digital : Kognitiva aspekter på äldres interaktion med pappersbaserad respektive digital kollektivtrafikinformation - ett situerat perspektiv
Samhällets digitalisering innebär stora möjligheter till spridning och återbruk av informationsamtidigt som digitala klyftor skapas. Bland de medborgare som inte till fullo anammat den nyatekniken återfinns en stor grupp äldre, något som påverkar dessa individers möjligheter till en höglivskvalité i form av delaktighet, oberoende och god rörlighet. En aspekt i detta sammanhang äräldres möjligheter att åka kollektivt och på egen hand planera och genomföra resor, något somförutsätter en god tillgång till och förståelse av kollektivtrafikinformation. Föreliggandeexamensarbete avser här att belysa kognitiva effekter av det skifte i interaktionsmiljön som sker närkollektivtrafikens tids- och linjeinformation digitaliseras. Studien baserar sig på en situerad ansats tillmänniskans kognition, ett teoretiskt perspektiv som innebär att tänkandet baserar sig påmultimodala konceptuella erfarenheter.

"Underhållsfria fönster" : I vilken utsträckning är dagens "underhållsfria" fönster underhållsfria och hur ser man
AbstractThe aim of this examination paper is to get an overview on the ?no-maintenance? windowsthat exist on the Swedish market, like plastic and aluminium windows.By way of introduction the reader gets knowledge in the background and problemformulatethat this subject has. This introduction explains why it has become so popular to changeyour windows into plastic- and aluminium windows and there is an existing scepticismagainst PVC and aluminium as construction material for windows.The main part of this report is constructed by segments of interviews where bothproducers of windows and stakeholders gets to answer questions about their viewing onno-maintenance windows from a material and construction point of view and where theproduction is headed to in the future. This is followed by an evaluation of a questionnaireon how pleased the house owners that changed their old windows to no-maintenancewindows are, followed by an inspection of windows made up from wood and an aluminiumclothing, windows made from only aluminium and PVC-based windows. It ends with atheory part about the materials PVC and metal based upon facts included in literature.By reading this report you can draw the conclusion that no window can be entirely nonmaintenancebut that the materials PVC and aluminium still are good substitutes for woodto lessen the maintenance..
Försörjningens paradox : En kvalitativ studie om statliga företrädares framställning av våld i nära relation
The aim of this study was to examine how state representatives prepared domestic violence, regarding the economic consequences of women exposed to violence. In order to achieve a profound and comprehensive view of the governmental keyfigures discussion we performed five interviews and studied selected governmental preparatory works between the years 1995-2015. We used theory on social construction as an approach and certain themes were more regular in our empirical material, which we compiled in three different discourses. According to our empirical material the economic situation of women exposed to violence is caused by inequality and gender power structure. The solution given by state representatives are referred to the municipality and social services.

Analoga möten i en digital tid - En kartläggning av Socialdemokraternas och Moderaternas dörrknackningskampanjer under 2014
2014 is a special year in Sweden: for the first time elections to the European parliament and the national elections coincides, creating a"Super election year". This year has also seen the rebirth of an old way of campaigning: door-to-door canvassing. For the first time in 50 years the two biggest political parties, the Social Democrats and the Moderate Party, have decided to create a campaign based on personal meetings with the voters in their own home. To investigate this old-new way of campaigning, this study presents an overview of the history of door-to-door canvassing in Sweden and the research in political marketing associated with the phenomena. Based on that, a new model is constructed to help analyze and map the Swedish canvassing-campaigns.
