This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

The purpose of this study is to evaluate an existing user interface. The company in question has a web-based user interface (available through logging in via their website), but they are interested in making the process of using the interface more convenient and the interface more accessible, so that users without a background in computing can properly manage the interface. At the same time they want to apply additional functionalities in order create and to manage increased traffic on the company?s website. For this reason it is important to take into account the issues involved in human-computer interaction (HCI) as well as aspects of cognitive psychology in order to make the tool and the web interface more usable, more motivational, and therefore more efficient and professional.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

The purpose of this essay is to explore the actor network of a high technology company in the textile industry called F.O.V. Fabrics. The background for doing this is a recent project, which we choose to call the Salt & Paper Battery Group, aiming to commercialize a newly discovered technology ? a battery based on cellulose from an alga. We start by examining a range of network theories in order to eventually shape a framework of our own.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

The purpose of our study has been to analyze the character of the interaction between music labels and media and to examine to what extent the artist brand is being considered in music labels relationship with media. This has resulted in our research question:What characterizes the large music labels relationship with media?For this study we have used a qualitative approach to achieve a deeper understanding of our chosen topic. We have conducted seven interviews with representatives from both major record labels and media companies with great knowledge about our subject. Five of the interviews were conducted face-to-face and two were performed via e-mail.In the final chapter we answer our research question and thus present our conclusions.

Family centres are established to serve families with children and the personnel usually consists of units of social-workers, preschool staff, paediatric nurses and midwives. The purpose of the study was to examine the social-workers preventive work with families at the family centre. To fulfil the purpose, a qualitative interview with five social-workers was conducted. The theoretical framework referred to attachment and empowerment theory. The results of the study showed that the main part of the work consists of giving advice and support to parents.

Narkotika- och alkoholmissbruk är ett hälsoproblem i hela världen och nyktra missbrukare är en utsatt grupp i samhället. Vid missbruk är det inte bara intaget av narkotikan eller alkoholen som medför skada. Hela livssituationen kan bli drabbad, inte minst kontakten med vänner och familj. För att hålla sig nykter, återanpassa sig till samhället och leva ett hälsosamt liv finns det många faktorer som är betydelsefulla. Syftet med studien var därför att undersöka nyktra missbrukares upplevelser av socialt stöd, fritidsaktiviteter samt utanförskap och delaktighet i samhället.

During the last decades the evolution of information technology and the increasing ability to access information have been discussed in many ways. In the beginning the focus was on the technology but now the discussion is more and more about the use of information and how to develop knowledge out of it. There is an ongoing discussion about the difference between knowledge and information. The subject of this Master s thesis is to find out if and how the Swedish elementary school has written into its mission statements to help the pupils to become information literate. For this purpose I have examined literature about information literacy and pedagogic as well as legislation and other documents that control how the Swedish elementary schools work.

Övervakningssystem har haft en viktig roll i samhället under en lång period. Syftet med dessa systemen har inte ändrats, det är alltid säkerhetsaspekten som har varit huvudpunkten. Effektiviteten på ett övervakningssystem beror oftast på den mänskliga faktorn, någon måste bearbeta bildflödet som spelas in för att dra definitiva slutsatser. Under senare år har dessa övervakningssystem, i takt med teknologins utveckling, blivit mer intelligenta. Metoder som tillämpar automatisk analysering av en given bild har introducerats, vissa av dessa tekniker har redan hunnit bli en standard. Denna studie ska utveckla en prototyp som använder sig av tekniken och stresstesta för att identifiera eventuella brister.

When searching for better and more practical interfaces between users and their computers, additional or alternative modes of communication between the two parties would be of great use. This thesis handles the possibilities of using eye and head movements as well as voice input as these alternative modes of communication. One part of this project is devoted to find possible interaction techniques when navigating in a computer interface with movements of the eye or the head. The result of this part is four different controls of an interface, adapted to suit this kind of navigation, combined together in a demo application. Another part of the project is devoted to the development of an application, with voice control as primary input method.

The purpose of this study is to examine young people?s opinions about libraries using social media for communicative and marketing purposes. There are three research questions: What do young people think about libraries using social media for communicative and marketing purposes? Do they want to interact with libraries in social media and, if so, in what way? Are their opinions and their will to interact influenced by what kind of relationship they have with libraries, their reading habits, and whether or not they use libraries? digital services? Prior research is divided into three themes: library development, marketing, and young people. The theoretical framework is made up of a combination of relationship marketing, using Evert Gummesson?s three catchwords relationships, networks, and interaction, and the engagement pyramid, as depicted by Brit Stakston.

This paper aims to provide a description of how knowledge can occur in Apoteket AB, anorganization that is operating on the Swedish pharmacy market. The purpose of this paper isalso to describe how the organizational learning occurs in the organization, and how theoutcome of this learning can be stored in the organizational memory. This subject is ofinterest since Apoteket AB experience changes in their external environment in that they nolonger have monopoly to sell pharmaceuticals on the Swedish pharmacy market. Earlierresearch claims that organizations need to develop new knowledge in order to take action, andthis development needs to be supported by the management within the organization.The collection of primary data was done by two qualitative interviews with employees withinthe organization of Apoteket AB.Our conclusions are that knowledge can occur in many forms, such as tacit and explicitknowledge. The vast majority of the knowledge within the organization is the information thatcan be found in the electronic database Aponet within Apoteket AB, and that is useful for theemployees in their daily work, and therefore is known as explicit knowledge.
