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.

Students at Jönköping School of Engineering were given an assignment from Jönköping municipality, to evaluate their decision support system, QlikView. The students have also developed proposals for improvement with focus on usability.The Jönköpings municipality has currently got 11000 employees and consists of nine different administrations. The target group for QlikView is approximately 600 first-line managers.The intention of QlikView is that the users can get an overall picture of their business by having all information in just one system.The purpose of the thesis is to obtain a picture of what the users think about the system today and present relevant suggestions for improvement, which the Jönköping municipality can use when the introduction of the new version of QlikView takes place. The research questions that the study aims to answer are:? Has QlikView got a user friendly interface?? How can the interface be improved to become more user friendly?Theories that this work is based on is Jacob Nielsens ten usability principles and Ben Schneidermans eight golden rules.

This report describes the process of developing a user-friendly and responsive archive website. The website is a Hi-fi prototype and was created for the company JG Communications, to serve as an archive for their customers? style guidelines. To create this website I have used HTML5 and CSS3 to make it responsive for various computer screens. I have also used PHP and some JavaScript to make some of the functions and Adobe Photoshop and Illustrator to make design elements for the prototype.

Det nya gränssnittet skulle också minska olycksrisken och göra användarna tryggare.

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

The aim of this thesis is to accomplish a user study on how e-book users experience the electronic book, the e-book, as an instrument for reading fiction. The study is based upon qualitative interviews with twelve e-book users and a small survey carried out at the Stockholm City Library. The purpose is to identify the users' incentive for choosing the e-book as a medium for reading fiction, elucidate if and how the interface of the e-book affects the reading experience, and distinguish if there are any factors common to the users in their choice of reading e-books. How the users look upon the future of the e-book is also discussed. Among the people asked in the survey we note little if any demand for the e-book as an instrument for reading fiction.

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product.The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed..

The project is about making a Re-Design of the Swedish Socialistic Newspaper ?Dagens ETC?. The background to the project is my search for commitment when I work with a specific customer or project and how importantthat commitment are?The project was from the beginning split up to three different phases. The meaning of the first phase where to make a re-design mainly based on a interview with Johan Ehernberg, the chef editor on ETC.The second phase was a design totally made of my own idea and creative view as a Graphic Designer.I had in mind to make the third phase based on the result of the first two phases.During phase one and two I reconsidered and decided to skip the third step and put more effort in to the two first ones.

Som mitt examens projekt har jag valt att forska kring frågan "Hur skapar man en unik design?" och använt det genom att skapa en grafisk profil till mig själv..

Transcending sound design is possible. There are unseen possibilities and a great potential for improvement and development in sound and music design ? but there is a great difficulty penetrating the obstacles that lies in the way for such development to take place and to exist. The difficulties in being negotiable and productive lies more within the limits of the audience it has to gain, than in itself. It is as though music and sound design has to evolve very slowly, in an almost evolutionary style; one step at a time, to be accepted.

This thesis examines the problems related to IT in the Swedish healthcare system, specifically the drug searching part of the electronic healthcare systems used in Sweden. The question formulation is divided into two questions: What parameters and functions are of greatest importance when performing a search on drugs, and how should these be presented in a graphical user interface? Thus the purpose is to answer these questions through developing a design concept, in the form of a prototype, which describes how a drug search can be carried out.The entry point is a central quality checked drug database that is managed and owned by Swedish county councils and regions. The problem is attacked through user-centered methods where interviews of physicians and developers, in conjunction with observations, are used to give an overview of the problem area as well as to specify a requirements specification for the prototype that this thesis aims to develop. The thesis result is a requirements specification in combination with a prototype that exemplifies how drug searching can be performed, the prototype is based the requirements gathered from the interviews with the user group of physicians..

The IT industry is constantly evolving and it's more or less a requirement today for web developers to be familiar with and to be able to develop for all platforms. A technique that has taken hold and is now widely used is responsive design. Developing responsive design means adapting the layout to the viewing environment; the screen size. Another useful method when developing for different devices is the mobile first theory, which means developing for the mobile screen first. This is done to scale down the site and to clear unnecessary information in order to provide a better user experience.
