The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.

The aim of this Masters thesis is to examine the use of IT, that is the Internet and other applications of personal computers, among seniors 65+. It also deals with issues of access to IT for seniors in public libraries. The theoretical background of the study consists of Rogers "Diffusion of innovations", Hektors categories of information activities, and the Swedish IT-commissions categories of motives and prerequisites for the use of IT. The research questions focus on factors motivating the use of IT, the extent and the purposes of IT use, the consequences and the barriers that IT-users experience, and views on IT in public libraries and IT courses, respectively. Qualitative interviews were carried out with nine senior IT-users.

The purpose of this master´s thesis is to examine how the cultural exchange function of Swedish libraries may be perceived on their websites. A further intention is to examine how the library websites are used at the present. Two quantitative web-based surveys have been sent out to a great number of Swedish public libraries. The first survey was directed to the webmasters of the libraries, in order to review the different services offered by the Swedish library websites of today. The second survey was conducted with library directors, in order to visualise what services they consider ought to be present on their own library website.

Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions.

In today?s computerized society more and more companies choose to utilize new applications that can ease the way of handling the information. For many of us is imperative that the process as efficient as possible if one takes in consideration the size of savings that this new application can bring.The developer of the evaluated system is SYSteam AB Huskvarna and they are the ones that gave us this assignment. The application that we evaluate is SCM (Secure Connection Manager). It is already used today by big companies such as Telia and Ericsson to search for errors in telephone servers placed all over the country.

Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

The aim of this thesis is to investigate what information needs arise from the interest in music, which sources are preferred, how this information is sought and what part does the public library play in providing music materials. Brenda Dervin`s Sense-Making theory is what serves as a theoretic framework for this study. A qualitative approach was undertaken in the investigation and nine interviews were conducted with people interested in music. Findings indicate that different ways of acquiring information are used depending on the situation in which the information is needed and also what kinds of music people prefer. The main findings of this study suggest that people interested in music are keen to constantly discover new music to perform or listen to.

Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.

The aim of this thesis is to examine one part of Amazon.coms recommender systems: Similar Items. The purpose is also to show the difficulties with subject access, i. e. to find a similar book to the one you just read; problems with traditional systems versus the usefulness with recommender systems like Amazon.coms Similar Items. Similar Items presents a set, a cluster of related items to a given item based on customers co-purchase.

We are living in a society where the digital technology is a tool that integrates into our life and changes our daily life and the way we communicate. The easy access to information and the opportunity to communication change the schools organization and demands new ways of teaching with and in contact with the surrounding world. That is why it is interesting to know how teachers can create an education environment with support of digital tools that fulfills a meaning for themselves, the pupils and the goals of the curriculum. This study is about how six teachers in one elementary school creates an education environment with support of digital tools and how they think the affect the pupils cooperation, communication and participation.The theoretical frame for this study is built in a sociocultural perspective, where people learn and develop through participation in social practices. To get the understanding of how teachers are thinking about the challenges and possibilities that digital tools have in the education environment, I choose a qualitative research method.

Throughout the history, the theories which have shaped our cities have varied from time to time. We have gone from a city development characterized by spontaneousness, where commerce and people side by side shared the space, into a function-based planning where people and functions are being increasingly separated. Regardless the forms of planning the city design causes implications for those who live there when the physical environment controls were we live, work and meet. In today's society where `sustainability ' has become a watchword the current community planning needs to be questioned so we, in the best possible way, can meet future changes. Searching for new planning strategies is part of this and in this essay the term `mixed-use´ will be investigated and analyzed in terms of its social aspects.
