Prestandautvärdering av firmwares baserade på öppen källkod för routrar/brandväggar på MIPS-arkitektur : Jämförelse mellan Open-WRT, DD-WRT och Tomato firmware
Den här undersökningen jämför prestanda hos tre olika firmwares som är baserade på öppen källkod. DD-WRT, Open-WRT samt Tomato Firmware för MIPS-arkitektur. Testerna följer två RFC som beskriver hur en prestandaanalys av ett nätverk ska genomföras.De sammanfattade resultaten pekar på en vinnare som presterat generellt bättre genom alla tester och det var Tomato firmware. Dessa resultat är hämtade från tre olika tester: genomströmningstest, svarstidstest och test med samtidiga sessioner.Undersökningen visar också att prestandan rent generellt är väldigt jämlik över alla firmwares i de olika testerna. En viktig aspekt är att det finns ingen överlägsen vinnare, vilket beror på, till exempel, hur konsekventa resultaten varit.
VRA-PROGRAMVARA MED TILLHÖRANDE STYRELEKTRONIK
This thesis has been done at the Unversity of Örebro for Örebro University Hospital (USÖ). In our work we have developed a product for hearing tests to determine hearing thresholds of small children. Our product contains software and a control surface for controlling two separate screens. One of the demands was that our software could handle big file libraries. Reliability and simplicity were essential for the user.In our work we have utilized programming of both microcontrollers and Windows software.
Vetenskaplig publicering i förändring ? En fallstudie av en svensk högskolas implementering av ett öppet digitalt arkiv
Since the beginning of the 21st century the Open Access-movement, which advocates free online distribution of scholarly information, has gained momentum. Authors can provide Open Access to their work in two main ways: by depositing a copy of their research output in an e-print archive and by publishing in Open Access journals. During the past few years, universities and other research institutions throughout the world have established institutional repositories to manage, preserve and provide access to the intellectual output of the university/research institution. The purpose of this master?s thesis is to describe the implementation of an institutional repository at the Swedish University College of Borås.
Patogenes för prostatacarcinom hos hund : en jämförelse med människan
This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute.
Barns fria lek : En socialpsykologisk studie
AbstractGroup processes within the free play- in a socialpsychology perspective In our socialpsychology study we have demonstrated how children?s free play is by observing 2-5 years old children in preschool. We have also interviewed two preschool teachers. The major subject in this study is how children?s group processes expresses in their free play.

Utvärdering av Mock Objekt Bibliotek : ur ett interaktionsbaserat perspektiv
Att skriva enhetstester är en viktig del i nya populära systemutvecklingsmetoder som extreme programming. Med testdriven utveckling skriver man testerna innan den källkod som skall testas. Ett vanligt problem med dessa tester är att de blir beroende av delar i systemet som inte är intressant för själva testen. Mock objekt är en teknik som gör det enkelt att isolera tester från allt som inte är relaterat till det som skall testas.Det finns två sätt att se på mock objekt. Den traditionella synen är att mock objekt skall användas som ett verktyg vid isolering av externa system.
Barns lärande och meningsskapande i den fria leken : En intervjustudie om fem pedagogers syn på den fria leken och den fria lekens lärande och utveckling
The purpose of this thesis is to study five pedagogue?s view of the free play and their view of the importance of the free play for children´s learning and development. I have chosen to use a qualitative research method in the form of interviews with five pedagogue´s from a preschool. The main research questions asked were:What have the pedagogues of view on the free play? How important believe the pedagogue that the free play is for children?s learning and development? What has emerged in the study is that educators have a positive view of the free play. They believed that the free play is important for children´s skills.
ROUTERMJUKVAROR BASERADE PÅ ÖPPEN KÄLLKOD : Jämförelsestudie mellan open source routrar
En router kan i dagsläget bestå av vanlig X86/PC-hårdvara vilket medför att hårdvaran inte är lika låst som den hos vanliga hårdvaruroutrar. Vidare kan dessa X86/PC-routrar köras med öppna programvaror. Många gånger är även dessa programvaror gratis och det gör att dessa mjukvaruroutrar är billiga att införskaffa. Detta arbete har studerat ett urval av tre mjukvaruroutrar för att se ifall det fanns några skillnader mellan dem. Det som undersöktes var prestanda, funktionalitet och support.
OSS-baserade e-postlösningar : En fallstudie
Syftet med studien är att analysera möjligheter och begränsningar med att använda programvaror baserade på öppen källkod för att förvalta en organisations e-post där utkontraktering inte är ett alternativ. Detta baseras på tio krav som identifierats som relevanta i relation till e-postlösningar. Inom studiens omfattning representeras OSS(Open Source Software)-lösningarna av programvarorna Zimbra Collaboration Suite, Citadel och Kolab Server. För att undersöka styrkor och svagheter hos dessa har hybridmetoden action case tillämpats. Genom ett interpretativt och iterativt närmande har representanterna ställts inför de identifierade kraven och deras förmåga att leva upp till kraven har analyserats.
Lek i förskolan : En studie av fri och styrd lek
The purpose of my study is to examine how four teachers reflect on free play and controlled play in preschool. What are their reflects concerning free play, controlled play and children?s development and education. The main focus of this research is the experiences of the teachers and I compare their perspectives against each other regarding free and controlled play.To be able to realize this study, I propose the following questions:What kind of vision does the teacher have concerning free play and controlled play?According to the teacher, how does playing affect the children?Which development areas are affected by participating in the play?This is a qualitative study, based on interviews with four teachers from two different preschools.
Lek och lärande : en studie om fyra pedagogers syn på den fria leken och dess påverkan på lärandet
The purpose of this study is to find out how four preschool teachers view children?s free playing and its impact on their learning. My main questions are:How do the teachers view the children?s free playing?In what ways does the children?s free playing affect their learning, according to the teachers?This essay is based on a qualitative study in which I have interviewed four female preschool teachers of different ages. I highlight various theories of children?s playing and learning in preschool, by theorists such as Vygotsky, Lillemyr, Knutsdotter Olofsson, Lindqvist, among others.
Integritet och långsiktig användbarhet hos textdokument : En avvägningsproblematik vid digitalt bevarande
This thesis is about a potential trade-off between integrity and long-term usability in the choice of file formats for preservation of text documents. Five common formats are discussed: plain text, PDF/A, Office Open XML Document, Open Document Text, and Markdown. The formats are compared with respect to four criteria related to integrity and usability and to the records continuum model: support by widely used software, stability, rendering of contents and reusability.It is concluded that no single format is optimal with respect to all four criteria, when it comes to preserving typical documents in a modern environment, with more or less complex formatting and document structure. Therefore, the feasiblity of using two or more formats for preservation of a single document (e.g. PDF/A combined with Markdown and/or Office Open XML) is discussed.
Masshantering av schaktmassor : en jämförelse mellan traditionell masshantering och GPS-styrd masshantering i realtid
The purpose of this report is to analyze the advantages of using programme software to monitor masshauling instead of using the conventional method. A comparsion between different programs will also be conducted in an attempt to determine the most affordable. This report is written for NCC Construction AB to help them choose a software most fitting for future projects.The report is based upon literature such as information taken from the developers website, existing reports with similar context, interviews with sellers of the software and interviews with people working in the building sector.The result of this report shows that there are several advantages with investing in a software that helps the management of a project and that it is something that should be taken under consideration instead of the existing method. Topcon is a clear favorite following the inquiries comparisons as done, when they deliver a complete system and not only a supplement to the current approach. Scanlaser are just in the beginning of its development, and is so far only out with an early version of the software, while Topcon has been brought further in development and therefore has more features in the program.
Aspect Analyzer: Ett verktyg för automatiserad exekveringstidsanalys av komponenter och aspekter
The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.
