Utveckling av högspänningskontakt
This report describes the development of a high-voltage connector at the request of Scandinova Systems AB in Uppsala. The development process is described from the making of a customer demand specification, to the making of drawings for the manufacturing of prototypes. Scandinova develops high-voltage modulators, hence the need for connectors that can handle very large power pulses. Their current connector has several weaknesses that may cause the connector to melt or catch fire. The development began with a number of studies that included the modulator structure and the current connector structure and functions.
Biblioteksrummet som miljöupplevelse
The aim of this study is to understand how the library environment affects the experiences and feelings of public library users. In order to concretise this, the study sets out from the public library in Bollebygd. We wanted to find out how the library users experience the library environment. Does the library environment affect the meeting between library users? How does the environment affect their moving patterns inside the library? Which environmental factors influence the users' experiences? Our questions were: how do users experience the library environment - as a mediating space for information and culture? - as a social room and meeting place? The material used to attain the purpose of the study consists of qualitative observations and interviews, and literature studies.
Vårdnadshavares attityd, beteende och upplevda kunskap om ljudexponering och dess risker
Background: From a public health perspective it is of great interest to prevent the risk of noise induced hearing loss, because in Addition to hearing loss, tinnitus and sound sensitivity also may lead to other health problems. About 1,4 million people in Sweden live with some form of hearing loss and 25000 of them are children under the age of 16. Studies have shown that hearing loss among adolescents is increasing and it is often associated with sound environments in their leisure time. Lectures in hearing prevention has been conducted in schools for adolescents but have not reached the desired results. Objective: To enquire caregivers? attitude, behaviour and perceived knowledge about sound exposure and its risks.
PARS PRO TOTO? Tillgång till Internet som en del av tillgängligheten på sex folkbibliotek
Internet access has been a part of the range in public libraries for approximately a decade. The Swedish municipals, in charge of the public libraries, and the libraries themselves, have a great deal of saying in how they should be run, what to offer the public, how many hours they have to stay open etcetera. The Library law is very vague on many things, including public Internet access. Even though Sweden is ranked as first runner up worldwide when it comes to Internet penetration among the population (Internet World Stats 2007), approximately twenty percent in the 16-74 age group does not have Internet access at home, at work or at school (SCB 2006a). In this master thesis we try to determine, through personal interviews, how six of those in charge feel about Internet at their libraries, all located in medium-sized municipals (20 000 ? 40 000 inhabitants), why they have chosen the rules and regulations they have and their thoughts about what they consider to be the most important assignment of public libraries.
Informationssökning under graviditet: en kvalitativ studie om gravida kvinnors informationssökning via sociala kontakter
The aim of this thesis is to gain a deeper understanding of howsocial contacts can serve as information sources for pregnantwomen. Furthermore, we wanted to examine how women?scontext influences their information seeking and the barriers thatcan occur during information seeking. The theoretical frameworkis founded on Tom Wilson's model of information needs as contextdependent, and Pamela J. McKenzie's model of informationpractices in accounts of everyday-life information seeking.
Klassifikation av litteratur om film och TV ? En komparativ studie av Klassifikationssystem för svenska bibliotek (SAB) och FIAF Classification scheme for literature on film and television
The aim of this thesis is to compare two different classification schemes with each other and see what the differences and similarities are when classifying literature concerning film and television. One of the schemes is of general kind, Klassifikationssystem för svenska bibliotek (SAB) and the other is a special system, FIAF Classification scheme for literature on film and television. The focus of the examination is on comparing the structure, contents and division of firstly the main classes and secondly on comparing the notation and the auxiliary tables in the schemes. The theoretical framework of the comparison is based upon theory of classification but the conclusions drawn are though mostly of a more subjective character. In Addition to the comparison itself interviews have been made with four libraries, two with experiences of SAB and two with experiences of FIAF.
Globalt Ansvar : socialt ansvar eller organisatoriskt hyckleri?
Background: Ambiguity and confusion of ideas within the area of social responsibility have led to that companies not really know how to work with these types of questions. One way for companies to deal with their social responsibility is to affiliate to an initiative that exists and through this show their standpoint. One of these is Globalt Ansvar, a Swedish governmental initiative that is based on Global Compact?s principles and the guidelines of OECD. What does it mean for the companies when showing their point of view? Is this a way to gain legitimacy?Purpose: The purpose with the thesis is to judge if organisations? work with Corporate Social Responsibility gains more legitimacy by affiliating to Globalt Ansvar.Research method: A survey made through telephone interviews with representatives from all of the fifteen Swedish companies which today are affiliated to Globalt Ansvar.Conclusions: In order to give the affiliated companies more legitimacy, Globalt Ansvar has to be a legitimate initiative.
ABF som folkfostrare: 1920-1949
-1949 [26][upps-01.gif] The aim of this master thesis is to investigate how W.E.A. Workers Educational Association, took part in the great changes of society and in the modernizing process in the period of 1920-1949. The examination is based upon three journals of educational material that were connected with W.E.A. The question at issue is to show how the people behind W.E.A. aimed to educate and indeed educated the workers to modern people and moreso to see how the articles in fact were written and to analyse in what way they turn to the workers and get their attention.
En geokemisk kartering över området kring Nasa silvergruva : Effekterna av historisk gruvdrift i svensk fjällmiljö
The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.
Korruption i Estland och Lettland, en jämförande studie

Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.
Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In Addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.
