When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.

I denna uppsats beskrivs gränssnittsproblematiken i dagens webbläsare. Syftet är att undersöka om användargränssnittet i webbläsaren hämmar användarna till att sätta sina individuellt anpassade säkerhetsinställningar. En stor del vardagliga sysslor utförs via webbläsaren, exempelvis hantera bankärenden eller ladda upp bilder på sociala medier. Därför finns det ett behov av att webbläsarens gränssnitt kommunicerar olika säkerhetsnivåer och inställningar så att alla användare kan använda och förstå de inställningar som erbjuds. Med hjälp av teoretiska utgångspunkter söker vi svar på eventuella brister i webbläsaren med hjälp av användarstudier.

The aim of this Master's thesis is to examine the user discourses that can be identified in the public library field. Questions posed in this study are: what discourses can be found, what characterises them, how are users categorised and what does this categorisation imply. The theoretical starting-point is Ernesto Laclaus and Chantal Mouffes discourse theory. The method is text analytic. 62 articles from three library journals - Biblioteksbladet, Bibliotek i Samhälle and Ikoner are analysed through a model in four phases.

During the past decade, consumer health information-centers have been developed at the hospital libraries in Sweden in order to meet the increasing demand from patients and their relatives concerning consumer health information. In 1993, the hospital libraries in Falun, Västervik and Karlstad launched a consumer health information database called PION. The aim of this Master's thesis is two-fold. My first aim is to describe and discuss the principles of user-oriented evaluation. In my attempt to convey the theoretical discussion into the everyday life of librarianship, my second and most important aim is to conduct a user-oriented evaluation of the database PION.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

Detta arbete har utförts i samarbete med företaget Compute och fokuserar på att utveckla navigationsstöd för webbportaler med bokningssystem. Arbetet har delats upp i tre specifika mål: (1) integrera Information Foraging Theory (IFT) och Graphical User Interface principles (GUI-principer) genom att applicera dessa vid utvecklng av navigation för webbportaler med bokningssystem (2) konkretisera hur navigering kan förbättras på en webbportal med bokningssystem, utifrån ovanstående teroier och (3) arbetet skall resultera i en lista med rekommendationer som kan tillämpas vid utveckling av navigation. För att kunna  integrera IFT och GUI-principer har dessa i kombination med en teroertisk studie tillämpats vid prototyping. Prototyperna användes som verktyg för att konkretisera hur navigationen kunde förbättras på portalen. Prototyperna utvärderades och resulterade i en lista med rekommendationer.

This is a thesis on D-level. In a previous course, at our program Computer Science, we came up with an idea of how to improve/complement training for new employees who are situated in a stressful workplace at companies who are in a constant need of rehiring. We developed this concept and came up with an idea for a simulator that could train staff as well as relieve stress and tension for new employees. The idea matured and became a Serious Game simulator based on a dual-wield Wii-controlled PC-based simulator with Bluetooth support.The purpose of this paper is to produce a design concept for a simulator as well as conducting research on the topics: mental and physical learning abilities, psychomotor abilities, visual perception, hand-eye coordination, confidence, simulators and Serious Games. The conducted research will be the foundation for the design concept which will be implemented in our co-workers', Henrik Djerf & Daniel Gomez-Ortega, prototype.

Ticks and the diseases they transmit are of major importance throughout the world. In Uganda, cattle are the most important livestock from an economic point of view. Livestock keepers fear bi-directional transmission of tick-borne pathogens between their livestock and wild animals. This cross-sectional study was conducted to establish and compare the sero-prevalence of the tick-borne pathogen Babesia bigemina among randomly selected Ankole Long-horned cattle and European crossbred cattle on 30 farms in Kiruhura district, in two sub-counties near Lake Mburo National Park in South-western Uganda. Half of the farms were situated in close proximity to the park and thereby housed cattle with more frequent wildlife-livestock interface (Sanga), whereas the other half had less frequent contact (Kikatsi).

En av de svåraste utmaningarna som ett företag står inför är jämvikten mellan användbarhet och säkerhet, så att ingen av dessa väger över och på så vis påverkar organisationen negativt. Utifrån intervjuer med anställda har användbarheten undersökts, även samtal med ansvariga inom IT-säkerhet har givit förståelse för företagets arbete inom området. I det undersökta företaget kan man se att stor tyngd läggs på säkerheten, vilket kan påverkar användbarheten för användarna. Eftersom det i nuläget saknas en utredning och ett riktigt beslutsunderlag av vilka användare som skall ha vilka behörigheter på sina datorer, ges i slutet av arbetet rekommendationer till företaget gällande användartypernas fördelning utifrån säkerhetsperspektiv och ur användarnas egen användbarhetsuppfattning..

The dialysis ward at Karolinska University Hospital is a highly pressurized work environment filled with critical treatment situations where patient?s lives can be constantly in danger. Staff have to deal with a myriad of alarms and error codes in response to their patients varying ailments. The workforce at the dialysis ward lack controlled environment training, sufficient to address all of the potential treatment scenarios, with no risk of jeopardizing the patient?s condition.The purpose of this essay is to design and test the efficacy of using an IT based device for dialysis education at Karolinska University Hospital.The main topics this essay intends to address are:? Identification of user scenarios and training fields.? Prioritization of key training areas.? Utilization of IT in effective staff training.? Design of a conceptual prototype.The process focuses on the user and their needs.

This report is an examination paper in computer science at University of Växjö. The report will focus on the possibility to create adaptable systems and to cost calculate the work needed to modify a system to meet new demands. A project [demos] developed by Interactive Institute studio [12-21] in Växjö is the starting point in our work. They have during a period of two years developed a prototype of a system which intends to get youth and democratic selected representatives a communication platform where they may communicate with SMS. Today they are in a position when they want to develop the system for other user groups with slighter different purpose and to do that they need a more flexible system.

Human Computer Interaction (HCI) is a broad discipline that studies different concerns regarding interactive systems? development. One of the major interest points within the discipline is the reasoning behind building specific functionality into computers and the long-term effects that usage of systems will have on humans.Within Human Computer Interaction there are theories and frameworks how to involve a user in the process of developing new systems. In this paper focus is applied to the development process within developing applications for Enterprice Digital Assistants (EDA) and to what extent the end-users are involved in the process. Fazer Bageri AB has been choosen to represent a business corporation that uses handheld computers in their everyday tasks.The method used to gather information for this study has been by performing interviews and observations with key stakeholders at Fazer Bageri AB and MobiOne AB.

The purpose of this essay is to examine progression in user education atprimary and secondary school levels, specifically the role played byschool libraries, librarians and strategy documents in securingeducational progression. Progression is examined in the user educationprovided by the five schools, part of the same municipal schoolmanagement area which share the same strategy plan. The area, NorraFäladen, was awarded School Library of the Year in 2011 for its work,making it particularly interesting for this essay's purpose. The studycombines interviews with the area's three school librarians, who dividetheir time between the five schools, with an analysis of the strategydocuments that regulate user education within Norra Fäladen. Theanalytical framework is based on: AASL's model of progression in usereducation (Standards for the 21st-century learner); Ekström's model forsuccessful and active strategy documents; Kuhlthau's theory of thelibrarian's role in the information search process; and Limberg'staxonomy of the role of the school library.The study shows how a number of concurrent factors and prerequisitesinfluence how goals for progression in user education are met.

To have a tool that guides you when you work with a complex system can be helpful since the complexity of the work can be reduced. In this thesis I explore the possibilities to use a helper application whilst planning installations of access control systems. The purpose of the application is to provide support during the planning and at the same time make the user aware of the limitations that exist in the access control system ARX Access. By combining early user input and the theory of formativity, the result became an application written in Java..

The aim of this master thesis is to gain greater knowledge of interpersonal communication. This study explores on one hand how interpersonal communication can be used as an important part of reference work in a Swedish electronic synchronous reference service, and on the other how interpersonal communication affects the relationship between user and librarian. By using communication theory and establishing a positive relational contact with the user in the electronic environment, the outcome of the reference encounter can be successful for both the librarian and the user. Furthermore, the importance of recognising relational barriers is of great relevance to the relational contact. The scope of this master thesis is to find what relational factors are used and can be used in the interaction between user and librarian.
