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.

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

De senaste åren har marknaden för surfplattor växt massivt samtidigt som Smart-TV?s har kommit fram som en ny produktkategori. Detta arbete är en undersökningen i hur surfplattor tillsammans med Smart-TV kan användas för att skapa en bättre upplevelse för användaren. För detta utvecklades en applikation på en LG Smart TV som sammankopplades med en surfplatta för att visa information om ett pokerspel. Sedan utfördes en undersökning med intervjuer där hybridapplikationen jämfördes gentemot att bara spela på surfplattan.

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.

Aim: The nuclear accident in Fukushima, Japan, raised global criticism against nuclear power. In Sweden, the criticism has not been very visible and the government now allows a renewal of the nuclear power plants. The purpose with the study is to have a closer look on how Swedes in position of power motivate their positive attitude to nuclear power and how they conduct themselves to each other and to their opponents. The rhetorical perspective will be in focus for the analysing.Method: Four different artifacts represented by Swedes in position of power having a positiveattitude to nuclear power were chosen. Three rhetorical theories (the rhetorical arena, stasis andethos, pathos and logos) were used with the research question in focus.Result & Conclusions: The analyses resulted in conclusions about the strategies used by the participants such as: the importance of contexts, meaning for example that the greenhouse effect legitimizes nuclear power as a source of energy with important benefits.

The purpose of this Master´s thesis is to examine howchildren?s needs, based on the Convention on the Rights ofthe Child, are provided for by the librarians when they havethe opportunity to create new libraries. We also examine ifchildren have been involved in the process and in that case towhat extent.Our theoretical perspective is based on MarianneAndersson?s and Dorte Skot-Hansen?s model of the fourdifferent functions the library can have for their users. Inorder to illustrate the degree of children?s involvement weuse Roger Hart?s model of participation.The thesis is based on qualitative interviews with seveninformants working at six different libraries.As a result of the thesis we can see that priority have beengiven to the function concerning how to find your way in thelibrary as a user.

This study analyses how different companies offer customer support through social media andthe customer experience of it.Facebook emerged in Sweden during 2008 and today it has more than 800 million user acrossthe globe. Initially Facebook was created for individuals. However, over time, Facebook hasincreased its functionality to support the presence of companies as well. Today most companieshas got a Facebook page and through it, they can easily communicate with their customers.Customer support is one of the communication forms that Facebook is used for.1A questionnaire that received a hundred responses together with a survey of the differentFacebook pages was done in order to determine how the companies work through socialmedia. The results from the questionnaire and the survey was analyzed with different theoriesregarding corporate presence on social media and Facebook.The results shows that only a few people actually used Facebook for customer support butamongst the ones who did the majority thought it worked well.

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

This research focus on key groups; students with dyslexia, librarians and teachers, and interaction between these two professional groups regarding students with dyslexia. In searching for the exchange of knowledge and experience to meet dyslexic students needs, I have in this study turned the attention to librarians and their experiences with students with dyslexia.The purpose of the research has been through semi-structured qualitative interviews with four librarians, to explore and describe how they experience their work, in working with pupils with severe reading and writing problems, dyslexia, and interaction with teachers on this user group. The qualitative approach in the gathering of the empirical evidence is based on a desire to have an indepth and thoroughly understanding of the librarians experience.All informants in this study indicate that they see it as a natural part of their duty to keep themselves updated about dyslexia and what materials to suit the dyslexic user group. The informants have knowledge of dyslexia and have great knowledge and keep abreast on the latest technology of compensatory aids - alternative tools.The informants have primary a consulting and supply function for teachers and dyslexic students, where they are consulted on  suitable material in both fiction and facts in various disciplines. The informants highlights the importance of planning and preparation time to find suitable material, as audio books or easy read, so students who have a need for this also can be provided.
