Användarundervisning på webben design för lättillgänglighet och användbarhet
The aim of this thesis was twofold, on the one hand to compile a set of usability and accessibility guidelines in order to establish the characteristics of a user friendly website, and on the other to test these guidelines on eight library webcourses with user education to see how well they adhered to the guidelines. The methods used were literature survey and source studies. The guidelines found in the literature survey were divided into four different categories: document properties, structure and navigability, visual characteristics and accessibility. In order to establish the adequacy of the guidelines, I examined reference sources, mostly on the web. To a certain extent this examination has been based on HCI Human-Computer interaction theories.
Från luddig verklighet till strikt formalism : Utveckling av en metod för den semantiska webben
Internet is the world?s largest source of information, and it is expanding every day. It is possible to find all kind of information as long as you know how and where to look for it, but still it is only the words itself that are searched for. We have with this essay tried to find an approach that makes it possible to give the word a meaning or a context.We have, as a starting point used the Socrates method, which is a method that breaks down texts into its smallest elements and forms activities. We have redone these activities to ontologies by forming general and specific descriptions of the activities.
WEBBSERVRAR : En jämförelsestudie mellan proprietär och Open source webbservrar
Nuförtiden är det mycket vanligt att människor och företag använder en hemsida för att synas. Hemsidor kan vara uppbyggda på olika sätt och av olika datorspråk, men de måste i grund och botten köras på en webbserver för att kunna fungera som en webbplats.Det här examenarbete undersöker prestandan för proprietär webbserver och webbserver som är av typen öppen källkod. Webbservrarna prestandatestades på hur väl de klarar av att distribuera olika sorters material som är vanligt förekommande i dagens webbsidor. Resultaten ifrån prestandamätningarna visar att webbservern av typen öppen källkod presterar i regel bättre än de proprietära webbservarna. En litteraturstudie genomfördes även för att se hur funktionaliteten för webbservern av typen öppen källkod kunde utvidgas.
Bilder av konflikternas Sydafrika : Två svenska lokaltidningars rapporteringar om Sowetoupproret i Sydafrika 1976
In the year of 2006 I moved to South Africa for a year, a land that has fascinated me because of its history. During the time of my stay I became very surprised how strongly apartheid permeates the community where the white South Africans today are building walls around themselves. Through media we get surrounded with pictures that media creates and to find information regarding what?s happening in the world this is, most often, the primary source. Therefore I believe it?s interesting to explore how two different local newspapers from the county of Kalmar, with two different ideologies, present pictures of the same event, namely the revolt of Soweto in 1976 and how these two newspapers relates to racial policies.
Ingmar Bergman och musiken : En audiovisuell analys av Såsom i en spegel, Tystnaden, Persona och Vargtimmen
The research on Ingmar Bergman is comprehensive, however, there is one aspect of his artistry that has been regrettably neglected ? his use of music. Music always played a huge part in Bergman?s life, and it was also a great source of inspiration. The music was a structural component in the creating process and he often referred to his films as pieces of music and his actors as musical instruments.
Politecast : ett nytt kommunikationsprimitiv för trådlösa sensornätverk
Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.
Informationsöverflödets dystopi : En intertextuell diskursanalys från Future Shock till The Shallows
Today it is common to state that we are living in an information overloaded society. But there are many different definitions of what can be said to constitute Information Overload and there is a lack of substantial research on the subject. Conclusions in the available literature on Information Overload are often drawn on anecdotal evidence and carries a dramatized picture of the causes and effects of the phenomenon.With the tools of discursive analysis this two years master?s thesis explores how the phenomenon Information Overload is portrayed in six popular science books that deals with the subject: Alvin Toffler (1970) Future Shock, Orrin Klapp (1986) Overload and Boredom, Richard Wurman (1989) Information Anixety, Andrew Keen (2007) The cult of the amateur, Maggie Jackson (2008), Distracted and Nicholas Carr (2010) The Shallows. The result of the analysis shows that there is a common discourse of how the subject of Information Overload is represented, which stretches in and between the books intertextually.
Hydroakustisk kommunikation med bandspridningsteknik
This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.
Erfarenhet, föränderlighet och arv Gottfrid Adlerz. Om människans ursprung och striden om kulturvärdena
The purpose with this essay is to analyze Adlerz writing within the context of the fiery debate in the 1880?s between the liberal so called ?cultural radical? members of the student organization called Verdandi, and the conservative, uniform oskarian culture named after the Swedish king of the period. I have applied a version of Quentin Skinner?s method, which focuses on the context of a specific writing in order to find out the authors intention, the effect the author hoped to achieve. My questions regard certain themes I discovered in the text and, more importantly, the relationship between these themes and the surrounding debate.
Open Source-baserad utveckling av Document Output Management-lösningar
Det finns flera fördelar med att digitalisera företagets affärsdokument; bland dessa kan nämnas minskade utrymmeskostnader och lättare delning av information. En process som inte sällan utgör en del av det elektroniska dokumenthanteringssystemet är hanteringen av dokumentmallar ? området som detta examensarbete kommer att fokusera på. Att på ett enkelt och smidigt sätt kunna förena data från ett affärssystem med en passande dokumentmall (kanske i form av en serverkomponent) och, baserat på denna process, generera t.ex. en faktura eller plocklista är något som varje elektroniskt dokumenthanteringssystem värt namnet borde kunna.
Praktisk Fysik : Laborationernas och demonstrationernas vara eller inte vara.
Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..
Hybriddrift i stridsfordon, fördelar och nackdelar
Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.
VOX : sittmöbel för det offentliga rummet
A trend in modern landscape architecture is to design pedestrian streets so that vehicles and people move in the same area. By doing this, traffic tends to slow down. On the market though, there is a lack of furniture that corresponds to the requirements of these kinds of public places. Therefore, I have designed this furniture, called VOX, which is planned to be used on streets, schoolyards and squares. One objective has been to promote the product to the industry.To achieve this, I have been in contact with people from different professions, which have all influenced my designprocess.
Politiska mord- en rättfärdig strategi i kriget mot terrorismen?
After the 9/11 attack the United States declared war against terrorism, which launched a conflict between indefinable transnational networks and states. In this war it became clear that the strategies used in traditional wars between states were not sufficient. New strategies have been discussed, but without any concrete results.In this thesis assassinations of terrorist leaders ordered by states is being presented as a possible strategy in the war against terrorism. Assassinations have been used in all times to shift political power but is today not morally accepted. This thesis aims to show that when used under the premisses of the just war theory, the strategy can be equally morally justified as any traditional war.
Hantering av handhållna läsenheter - en kvalitativ analys av läsbegreppet på nätforumet MobileRead
The aim of this study is to examine reading on the MobileReadforums. The term ?to read? is extended to also cover bookcollection and usage of new technology such as mobile readerunits.A catalyst for reading on mobile reader units seem to be the needto always have access to the personal e-book collection. Apartfrom being a source for reading the collection of e-books alsoserves the purpose of extending the members self-esteem.A large portion of the activities on the MobileRead forum isaimed at making new technology comprehensible with the help ofprotocols to determine the usage of that technology. The processof making protocols also seem to be another way for the membersto extend their self-esteem.Traditional libraries are mainly seen as one of many sources for ebooks.Librarians are mostly perceived as being service mindedbut lacking in e-book knowledge.There is also a risk for miscommunication as the library hasdeveloped other protocols that defines an e-book and how itshould be used.This study is a qualitative analysis based on forum posts collectedfrom the MobileRead forum..
