The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..

This essay explores to what extent the Swedish language version of Google Images meets the usability requirements of average everyday users. Previously published studies on user behaviour and users? interface and search option preferences define the usability requirements, which are matched against Google Images? actual interface and search options. The retrieval method of Google Images is also briefly discussed, and users? opinions about Google Images too, as they come across in the previously published user studies.The findings are that Google Images lack some of the things that users ask for, but it still seems to be the most used image search engine among average internet users and more appreciated than other search engines.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

Studies have shown that user participation is a good method when improving or developing a product. The method gives a company insight in what the customer wants and needs. It has also been shown that user participation benefits all parts included. For example, it creates a greater relationship with customers than most other methods do. Webportals is one of the most interactive systems online and it gives companies a unique chance to improve and maintain their relationship with customers.

The purpose of this thesis is to reach a deeper understanding of the context of teachers? information seeking. Research in the role of the library in a learning perspective is in demand. To reach our aim we investigate what teachers say about their experiences of the user training during their studies and what effect it had on their information seeking as teachers. We interviewed four teachers and analyzed the transcripts of their sayings about their experiences of their information seeking during their education and a teaching profession.

Author: Gabriella Agné and Helena LarssonTitle: Disability policy program ? a case study of a municipals implementation of UNs Convention on the Rights of Persons with Disabilities.Supervisor: Marianne Westring-NordhAssessor: Ulf DruggeThis study aims to examine how a small municipal in southern Sweden works with the implementation of the UN Convention on the Rights of Persons with Disabilities and examine the assistant officers knowledge about this work and user organizations inclusion and user involvement.The study operates from a qualitative approach based on the results of nine semi-structured interviews with local politicians, assistance officers and representatives from three different user organizations.The results show that the municipal has chosen to work with the implementation of the convention by creating policy programs for their departments through dialogue with user organizations, and by mapping the accessibility to public places. The results also show that the assistant officers have been given no information regarding the convention or the policy programs from their employers and instead operate from national legislations and prepositions. The user organizations feel that they were initially included in the process, but that their impact has later been removed due to structural reorganization..

This paper is part of the research programme ViSuCity, a programme with the goal of creating more sustainable urban planning through the development of better visual tools, which ultimately means better communication between various parties of public planning. The paper concerns the implementation of MCE into a 3D program for visualization. Multi criteria evaluation (MCE) is a technique that has been developed during the last 20 years. It merges GIS with AHP, forming a decision making tool for localization of, for example, new buildings.The result is an automated tool that enables advanced analysis of geographic areas.The tool has a very high potential due to the completely automated MCE and it is adapted for people without a technical background, let alone formal training in MCE. It provides great opportunities to test different scenarios, something that should be an important advantage.

In writing this study, I wanted to examine which principles of organization that are possible for Swedish public libraries to use, and what these principles mean for the libraries customerorientation. This is done by examining a number of written sources, as well as studying the organization of six public libraries. I found several possible principles, but a number of principles have been more commonly used than others. Historically most public libraries were organized according to the functions needed to be carried out within the organization, but today it is much more common to use subject-based organizations, with some examples of organizing according to user-groups and needs. I have also encountered the possibility of organizing according to the sources that are to be handled, or the way in which these sources are used by the customers.

Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.

The purpose of this Bachelor thesis is to examine how user-friendly the OPAC of the Märsta public library is considered to be.Theoretical basis are HCI and Allwoods definition of usability. Issues are: Is the OPAC suited to its task? Is the OPAC user-friendly? How well does a user accept the OPAC? and What degree of competence is shown by users of the OPAC? The source material consists of six interviews in the form of .avi files. The method I have chosen is qualitative semi-structured interview form. The result is that, based on Carl Martin Allwood?s defini-tion and with exception for the using of help-resources, the usability of Märsta?s library OPAC can be considered less good..

This study is a thorough comparison between what people think about the website www.sl.se, which is a Swedish web-based travel planner for Stockholm metropolitan public transport (such as subways, busses and suburban trains), and how these views compares to the design of the actual website itself. The travel planner offers a wide range of functions and services for their targeted audience to find the fastest route between their current location and their destination. These functions are for example real time information on hold ups and malfunctions on different travel routes, and an interactive map of specific destinations so that the user can get a clear view of the area and nearby traffic stops. But how much does the average user care for these functions, and how often are they used on an average visit? What are the users? motivations when they visit the site? Earlier research suggested that there are services and functions on this website that are useful and well crafted, but that some people may not be aware of.

In my study, I have chosen to examine how the user interface and content must conform to design guidelines for responsive design makes it suitable for diverse desktop environment and for varied mobile platforms. The purpose of this study is to examine the extent recommended design guidelines based on scientific research has a positive impact on user performance and perception when using this study delivered hi-fi prototype. The goal of this study is to provide a Hi-Fi prototype with high usability that will introduce and inform the public about BrasilCine according specifications. Study findings from user testing and supplementary questionnaires show that the implemented technologies as design guidelines for responsive design and design features have a positive impact on user performance and perception. The study results are therefore relevant for further prototype development..
