Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

Outsourcing av urval och inköp : En studie av hur bibliotekariens kompetens och yrkesroll påverkas av Bibliotekstjänsts profiltjänster

Traditionally, the majority of Swedish public libraries have carried out most of their acquisitions through Bibliotekstjänst's binding booklets. In recent years, however, many libraries have complemented the binding booklets and other services from Bibliotekstjänst by other ways of acquiring books, such as Internet bookshops, while other libraries have stopped using the binding booklets altogether. There are various reasons for this development, such as Information Technology making it possible for librarians to compare prizes and services from different retailers. Another important reason is the need for public libraries to meet new needs from their patrons, while remaining on a restrained budget, which often causes a need for reorganization of staff and resources.As a way of meeting the new needs for libraries, Bibliotekstjänst has created Profile Services (profiltjänster), a service in which a library outsources its acquisitions to Bibliotekstjänst. The staff of the library, in dialogue with Bibliotekstjänst, design a profile for the acquisitions for the library in question, in order to determinate which types and genres of literature the library and its patrons are requesting.

Filmproduktionsprocesser : En jämförande studie om att filma analogt kontra digitalt

The art of producing films have been around for more than a century and the technology just continues to evolve. But although much has happened in 100 years, there are also processes, theories and practices that look the same now as then. I write this thesis because I want to find the differences between the analogue and the digital way of production. This study is based on a qualitative approach because my ambition is to seek the views concerning film production processes. The advantages of analogue film is that it contains more information than the digital formats and that it has a more cinematic style.

Energianvändning i restauranger i Umeå kommun

Efficient energy use in restaurantsUmeå Municipality wishes to combine energy issues with food control, and thus help restaurants to become more energy efficient. During March and April 2010, I visited seven restaurants and interviewed restaurant personnel about current state and application of kitchen appliances, using a checklist to make sure that the same questions were asked at all restaurants. The restaurants were all different sizes and offered different kinds of food. The study mostly focuses on energy efficiency by behaviour and not on location or technology. Almost every restaurant that was visited had the potential to improve in one or more areas, such as kitchen appliances, lamps and lighting fixtures, heating, cooling and ventilation.

Lättläst information i e-förvaltningens tid : En studie om lättläst information när myndigheterna satsar på webben

The overall aim of this thesis is to examine how Easy-to-Read information, used by governmental agencies, facilitates and limits the field of possibilities for the intended recipient, based on the information.This, in anera of e-government.The theoretical framework is based on two Foucauldian concepts governmentality and discourse analysis. Representatives from five Swedish governmental agencies have been interviewed and the results have been analyzed based on the following questions: (1) How do the representatives construct the category Easy-to-Read? (2) How do these representatives construct the recipients of Easy-to-Read? In order to broaden the understanding of Easy-to-Read, an important national level policy document, containing a summary of strategies and goals for e-government has also been analyzed based on the following questions: (3) How is the e-government constructed in the text? (4) How is the citizen constructed and positioned in the text? The collected material is analyzed using a discourse analysis inspired by Foucault.With the results from the interviews and the analyzis of the policy document, Easy-to-Read information has been discussed and examined as a technology to meet the needs of people with reading difficulties, putin an era of e-government.The findings of the study include the following: (1) The e-government is constructed as a service agency and the citizens are positioned as clients. Furthermore, the citizens are expected to participate digitally and be digitally competent. (2)Some of the representatives does not know, with certainty, to whom the texts are directed or if they are used.

Från hemtjänst till eHemtjänst

The number of elderly continues to increase in Sweden which puts pressure on the elderly care. Aproposed solution is to increase the use of information and communication technologies (ICT) inhome care to both streamline care and enable older people to manage on their own to a greaterextent. So far Västerås is the only municipality that has made a decision on an ICT solution, whichthey have chosen to call ?eHemtjänst? (eHomecare). The purpose of this paper was to investigatethe specific prerequisites and requirements for Gothenburg city regarding the potentialimplementation of eHemtjänst.

Informationskompetensen i användarundervisningen

This master thesis investigates the user education. Christine Bruce has presented a theory of information literacy in her research which has resulted in seven different aspects of information literacy. In this study I wanted to investigate what aspects there were and what they looked like in a practical educational situation. The methods used for this study were observation and a questionnaire. I analysed the observations by using Bruces aspects of information literacy to group the observed activities into the different aspects.

Augmented Reality i mobiltelefonen : En kunskapssammanställning med trafikinriktning

This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.

Vad gör vissa medarbetare mer nöjda än andra? : En studie om hur medarbetares upplevelse av kontroll och välbefinnande påverkar uppfattningen om den interna kommunikationen i organisationer.

Dagens samhälle ställer höga krav på individer att vara sociala, kommunikativa och inneha en förmåga att hantera ett ökande informationsflöde. Samtidigt som det ligger mycket ansvar på den enskilde individen att sålla bland stora mängder information har olika individer skilda förutsättningar att möta dessa krav. Studiens syfte var att undersöka om upplevelse av kontroll och välbefinnande hos medarbetarna påverkar kommunikationstillfredsställelse och föredragna kommunikationskanaler. Som teoretisk referensram har teori om kommunikation och subjektivt välbefinnande samt Rotters (1966) teori om Locus of Control använts. En kvantitativ enkätstudie genomfördes på en förvaltning i Tidaholms kommun i Västra Götalands län där de upplevt kommunikationsproblem i sin internkommunikation.

Uppföljning inom ett vårdvalssystem - En fallstudie av uppföljningen av husläkaruppdraget i Stockholms Läns Landsting

This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..

Lärares syn på teknikämnet. : En enkätstudie av pedagogers tankar kring teknik på mellanstadiet

Syftet med denna studie är att få en inblick i hur lärare på mellanstadiet arbetar med teknikämnet i skolan. Detta görs genom en enkät, vars frågor är upplagda efter tre frågeställningar: Vilka tankar har lärarna om teknik? Hur ser pedagogernas teknikundervisning ut? Vilket undervisningsmaterial använder lärarna sig av i teknikämnet? Totalt är det 65 lärare som arbetar eller har arbetat med teknik på mellanstadiet som deltagit i studien. Enkäten har visat på att de flesta lärarna som deltagit tycker att teknikämnet är ett roligt, spännande och intressant ämne som dock är svår bedömt, tids- och materialkrävande. Undersökningen visar även att de flesta lärarna tycker det är bäst att arbeta med teori och praktik varvat, då båda delarna behövs för att eleverna skall förstå teknikens innebörd i samhället.

Modelering av Wideband : Code Division Multiple Access

Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.

Kontraktsstyrning och kvalitetsindikatorers utformning vid kommunal upphandling : En flerfallsstudie

Management by contract is nowadays a common method within the public sector since the NPM overtook as paradigm with its mechanisms of control inspired by the private sector. The public agency is foremost a service provider where they interact with citizens in the service process. Swedish eldercare has significantly increased its expose to competition which means that eldercare can be executed not only by the municipalities own provider. Such an adaption increases the requirements to inspect quality and how the purchasers assure goal achievement by control. The outmost liability stays with the municipality to ensure that the service produces god care since their position as the service purchaser implies the responsibility to plan, precise and evaluate the required work that the executor has to accomplish.

Den trådlösa massan - svärmbeteende och kollektiv handling

This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.

Energisparläge i automationsindustrin : Potential för att minska tomgångsförluster med industriella styrsystem

Former studies have shown that a considerable part of industries? energy usage can stem from idle times in the production. This thesis, carried out at Siemens Industry sector, evaluates the potential for using the control system to automatically put machines into energy saving mode during idle times. The main part of the thesis consists of a case study performed on machine tools at a Scania production site in Södertälje. Through load measurements the potential for energy savings was determined.The results show that there is a great potential for energy savings during idle times at the site.
