Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.

AimThe aim of this study was to find out whether Motivational Interviewing can affect people to change their behaviour in form of increasing physical activity. What results do studies conducted at healthy adults using Motivational Interviewing with physical activity as an outcome present?MethodTo fulfil the aim of the study we chose a review process.

One of our reasons is that we think the subject usability is interesting, is that we think it is an important. Usability is maybe the most important element when you develop or choose a system because it can save money for the companies and give the users a more delightful and better work environment. The aim of the investigation is to find out if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. The objective of our investigation is to show if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. In our case we will try to see if Karlshamns AB:s recently implemented web portal is more useful than their previous application (Movex with interacting programs) One thought with the report is to give the system developers a perspective of how the usability can be in-house made applications versus standard applications.

Denna explorativa studie analyserar gemensamma och differentiella mönster för kommunikation och beteende hos användare i Hjälpforum. Målet med studien är att kartlägga aktiva användartyper med syfte att ge SVT kunskap om Hjälpforumets användare. Om forumadministratörer har mer kunskap om användarna i Hjälpforum kan de anpassa sin kommunikation utifrån användarnas individuella behov och öka deras förmåga att bidra med mer kvalitativ återkoppling. Detta kan i sin tur bidra till en positivare inställning och ökat förtroende hos användare i Hjälpforum. I denna studie kunde fem användartyper kartläggas i Hjälpforum med stöd av egen empiri och tidigare forskning.

The problem being examined is the disturbing noise that is created in an open plan office on a company working with a creative process, such as a newspaper or a communications agency. The purpose of this study was to examine the needs for today for a sound absorber in open offices and create and design a design proposal. The aim is also to develop a marketing material the product proposal. The problem has been broken down into the following questions:- How does the user look at the need of a sound absorber in an open offices solution today?- Does an interior designer apply sound absorbers when they furnish the intended environment? - How can a design that meets the needs that exists be achieved and to speak the user?The study is based on three choice of methods a literature review on selected topics that relate to the topic, an interview with an interior designer to explore how an interior designer applies absorbers in open plan office and finally an extensive survey that treats the user's needs and appropriate appearance for the product proposal.The design process has undertaken the following methods, design brief, requirements specification, functional analysis and sketches to produce the final product proposal.

The communication with government and municipality through Internet has in-creased during the last couple of years. Therefore we have chosen to focus our bachelor thesis in this particularly area and the needs for usable web services for the citizens. In this bachelor thesis we are studying a increasing group users, namely elderly citizens. During the study we have analysed E-governments ser-vices usability through usability tests. The combination of conversations and meetings with individuals, observations of interactions and literature studies give us the opportunity to explore the users needs.

The purpose of this essay is to analytically review and discuss architecturalcompetitions, mainly through the general views of a few selected workinglandscape architects, architects and scientists. I have studied the moral and workethicalaspects of using graphical presentations as a mean to draw attention,rather than trying to meet the set program points.My results are derived from e-mail interviews, literature studies and studies ofthe competition entry Stockholmssfären from the competition Stockholmsportenwhich was held in Sweden early 2011.The literature studies have shown that the available literature on architecturalcompetitions and research on the subject is biased towards architecture ratherthan landscape architecture. Worth mentioning is also that there is not a lot ofavailable literature, mainly due to lacking research on the subject.The informants for the interviews were selected based upon their academicmerits and/or experience of working with or doing scientific research onarchitectural competitions. The landscape architects? opinions regardingarchitectural competitions turned out to be in many ways alike ? they seemed tohave a pretty relaxed view of competing in architecture.

AbstractThe aim of this literature review was to describe the quality of life in stoma patients after stomasurgery. Different combinations of the keywords ?stoma?, ?Quality of Life?, ?stomasurgery? were used when searching in the databases Medline, Cinahl, Academic Search Elite and PubMed. A total of nineteen articles were used in the result. Fifteen studies had comparing design and four studies had describing design.

New technological innovations like tablets and smartphones have a taken significant market share on the web and puts new demands on webpages, the user interface and compatibility among different client devices. The full test of a web-based system prior to the publication is often regarded as an important part of the process to create a complete and successful website. This bachelor thesis investigates the possibility to analyze mobile-adapted web sites using a system that first records the visitor's activities and then replays them for an expert analyst to provide valuable information to developers about how their site can be improved.The essay begins with a litterature study on today's most common web development tools and then examines the possibility to apply them during the development of the analysis tool. The work also describes two methods, pair programming and waterfall method used during the project. Three different evaluation methods are presented and one of the models is applied on the finished system.The project results in a web-based analysis tool written mainly in JavaScript using the jQuery library.

Umeå University currently uses two Course Management System, Moodle and Sakai (Cambro). Both Moodle and Sakai are based on open source code and are today the two more popular choices among Swedish Universities. They both have different strengths and weaknesses both from a technical perspective and a user perspective. This can create problems for a course responsible/teacher when it comes to planning the course structure at a distance course but also when planning the course structure on a campus course that uses a Course Management System. With this as my starting point my formulations of questions become:How do the Course Management Systems that Umeå University uses differs, both from a technical perspective and user perspective?What possibilities is there in the Course Management Systems to use a different Course Structure?Is there a noticeable difference on the view of Course Management System of teachers and students at different departments?The purpose with my essay is to create a basis that course responsible/teacher can use to plan the course structure.

The aim in this project was to spread play in the city and acrossgenerations. My way of approaching this challenge was to explore theborderland between playground equipment and street furniture. Thisopened up many possibilities to afford play in places where playgroundequipment often is excluded.The goal was to create one, or more, furniture with play value. The targetgroup was all vivasious people spending time in the public outdoorspace. Through User studies, a lot of serious playing and a lot of testing,the project resulted in a bench called Rollin´.

Safety, its a word not commonly associated with elderly people living alone. There is however a device that is supposed to bring safety, and enable elderly people to continue living in their present household - an emergency dialer. However these devices does not serve their own purpose in terms of design. Thepurpose of this study is to create an emergency dailer that everybody would want to put on their wrist or bedside table. The market for these devices have looked the same for the last twentyfive years, despite of society´s advancements in both design and technology.
