Som en del av HTML5 har den många användbara funktioner som öppnar upp nyamöjligheter för utvecklare och för vad webben kan användas till. Som plattform har en hemsida som gåttunder projektnamnet Partify använts och här har Web Storage testas att användas för att undersöka hurman bäst använder tekniken. Rapporten innehåller ingående fakta om hur Web Storage är uppbyggt ochhur man använder det.Efter jämförelse med dagens vanliga teknik, cookies, finns tydliga resultat på hur väl Web Storage hävdarsig när det gäller säkerhet, prestanda, användarvänlighet och funktionalitet.
Biggi förvaring : förvaringsskåp för utomhusbruk
Manne Bouveng, CEO of Optimel AB had an idea for a new kind of storage cabinet that could be adapted especially for townhouse owners. I came in contact with Manne by a familiar friend for us; we met and decided that it would suit as my thesis.What was needed to be done was a market research that would possibly show that there was a need for a new kind of storage cabinet on the market. Because of this we continued to work on the basic idea. We came up with a solution where we developed a box that resembles Optimels known mailbox Biggi Rondo, the storage cabinet is a new solution of a storage cabinet, adapted after a market that need of a lot of new space. The solution is based on a simple construction which sits an inside hang-off device which can attach tool hooks, tool holders and shelves and so on.The purpose of the assignment was to develop a new type of storage cabinet with some kind of solution to attach tools and other garden related stuff. With this we have succeeded and the concept meets the requirements we set ourselves at the beginning of the project..
Säkerhetstänkande integrerat i systemdesign via formaliserade metoder
Systems development methods mirror different organizational perspectives, and not all methods are formalised, but what they have in common is the purpose of structuring and supporting systems development processes. Which method would be the most suitable may be determined by the systems development context at hand, because every systems development context is unique. Information is a valuable asset in today?s organizations, and it needs to be protected against both internal and external security threats. In our essay we aspired to find and present suggestions as to how systems developers can include security in the very design based on formalised systems development methods to create systems that are better prepared to meet the security challenges of today.

Ståndort och växtval på takterrasser
In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

Forskningsfronten inom informationsvetenskap ? en bibliometrisk analys
The aim of this study is to analyze and describe the research front within information science. To reach this purpose we ask the following research question: Which research themes can be identified within the subject field of information science by using bibliographic coupling in combination with cluster analysis.The data for our study consists of articles from the journals Journal of the American Society for Information Science and Technology and Journal of Documentation throughout the years 2004-2006. The bibliographic information from the articles was analyzed with the combined methods of bibliographic coupling and cluster analysis. This gave fifteen clusters within which we identified research themes. When analyzing these results we found four main fields of research within the research front of information science: Information retrieval, bibliometrics, knowledge organization and information science as research discipline.

System, stabilitet och makt - informationsdiskursen i Organizing Knowledge
TitleSystems, Stability and Power. The Discourse of Information in Organizing Knowledge.AbstractThe aim of this Master's thesis is to inquire into the consequences of an unequal distribution of power between information discourses in the field of knowledge organisation. A deconstruction of Jennifer Rowley's and John Farrows introductory textbook Organizing Knowledge from 2000 is related to the major discourses of information in LIS. Questions posed in this study are: What meaning is ascribed to information in the material studied? Which information discourses are given a dominant position? Which are excluded? and: How does this affect the construction of the library and information science student's identity, in relation to practices of knowledge organisation? The theoretical framework is provided by Ernesto Laclau's and Chantal Mouffe's theory of discourse and combined with techniques for text analysis originating from the work of Norman Fairclough.The analysis reveals a strong domination of a cognitive discourse of information that underlines the importance of information systems for the organisation of knowledge.
Open Archives Initiative om "öppna arkiv" och den sociala kontextens betydelse
There is an ongoing evolution in scholarly communication. The traditional way of communicating scholarly results through scientific journals is beginning to be replaced by other means of dissemination. One new channel for scholars to communicate their results is digital publication in so-called open archives. An open archive is a kind of full text database, where a scholar may archive/publish his or her articles, as a complement or a substitute to publishing in scientific journals. There are discipline-oriented archives and institutional archives.
