In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound. The result was a rule-based agent for notification of email, which primarily uses sound as interaction style..

Background: An evaluation of analysts´ forecasting ability is interesting since their estimates constitute an important part in stock valuation and investment decisions. The recent years´ development in the stock market has lead to criticism of analysts? deficient forecasts. Purpose: The purpose of this thesis is to evaluate analysts´ forecasting ability concerning companies quoted at Stockholmsbörsen between 1987 and 2002. We also intend to discuss possible explanations for analysts? behavior in case of deficient accuracy.

In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.

Background: HIV is a worldwide spread disease with many deaths. People with the disease have previously been met with attitudes, stigma and discrimination in various contexts. A caring relationship should be built on empathy, respect and communication, where the patient is not seen as their illness, but as a person. Today, there are laws that are there to protect the patient, however, there is a lack of knowledge about what is current. Health care workers knowledge in the 2000s has improved, but there is still a lack of knowledge.Aim: To illustrate how patients with HIV experience health care.Method: The literature review was conducted with twelve scientific articles of which two articles were quantitative and the other qualitative.Results: The results revealed three main themes; Different expressions of fear, Perceived negative attitudes and stigmatization, as well as The wish to be lovingly treated in health care.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

This report describes the development of an application in collaboration with Designingenjörerna AB. The company has worked for a long time with a community platform and they required an application where users can create their own unique profile representations, called Avatar Creator. An Avatar Creator is computer based application, which makes it possible to create a virtual character. The problem area behind this is that, large websites require a lot of administrative work when people upload profile pictures on different community pages. They can contain abusive material or pictures of other people rather than those who created the profile.The questions in this report are, how can an Avatar Creator help user to get a unique profile of himself? What are the advantages and disadvantages of an Avatar Creator? How to create a user-friendly application?To understand how an Avatar Creator works and get ideas to create an application, exiting Avatar Creators were reviewed on the Web.Collaborative work with Designingenjörerna AB was done to pin down the requirements for the Avatar creator application.

The technological development contributes to an increase in advertising when it comes to media. Those who are working to develop advertising are constantly looking for new ways to reach consumers in unexplored contexts. Web TV is a relatively new technique that involves the distribution of television across the Internet. This study intend to investigate how users perceive advertising appearing on web TV, and contribute to the knowledge about how advertising adapt to new media. To reach the results of this study, we used quantitative data, collected in the form of web-surveys and qualitative data collected through semi-structured interviews.

The aim with this study was to learn about the experiences of field workers and welfare officers in the field of possible self-harm behavior among young people.Our problem was: Do field workers and welfare officers treat young people with deliberate self-harm differently and - How do field workers and welfare officers describe deliberate self- harm?Our study was conducted through qualitative semistructured interviews with twelve interviewee?s.The result of this study shows that there is a difference in how young people with self-harm behavior are being treated - based on their gender.One possible cause for this result could be the old tradition mindset of viewing boys and girls differently ? and thus, treating them differently when they seek help.Our study shows there is a possibility of treating boys and girls differently ? which shows that we made a thought-provoking point.

Syftet med denna studie är att undersöka om det finns ett samband mellan opredicerbara föräldrar och förekomsten av både interna och externa beteendeproblem hos ungdomar. I studien undersöks interna beteendeproblem såsom låg självkänsla och depression samt de externa beteendeproblemen brottslighet och aggression. Studien baseras på 1018 ungdomar i åldrarna 13- 15 år. Studien utgår från en enkätundersökning där fem olika skalor används för att mäta ungdomarnas självkänsla, depression, brottslighet och aggression samt hur konsekventa deras föräldrar är. Resultaten visar i allt väsentligt att de ungdomar som har både interna och externa beteendeproblem är de som rapporterar högst i opredicerbarhet hos sina föräldrar..

The number of smartphones are constantly increasing, 2010 approximately 200 million unitswere sold globally and the figure is predicted to increase to 1 billion in 2016. The increased useof smartphones also carries many risks, for example many smartphones are connected to theInternet. This is a possible way for hackers to gain access to user devices. Smartphones are wellrepresented in research on its safety, while research on its use and users? awareness often leavesmore to be desired.

A large part of the Namibian low income population lack access to grid distributed electricity. This mean they are effectively shut out from basic functions such as lighting, information technologies and hygienic food handling. Hence, finding ways of providing affordable off-grid electricity is an important, not to say critical, task.This master thesis is an innovation and concept development project that has been carried out in cooperation with organisations in Sweden and Namibia. The purpose of the project has been to (1) develop a concept for off-grid electricity supply in Namibia and (2) to gain a deeper knowledge within the area of innovation and product development for the Base of the Pyramid population, i.e. the poorest, but largest, socio-economic part of the global population.Essential in this project has been to acquire user understanding and to identify user needs to create a foundation for developing the concept.

Artificiella ekosystem är en tillämpning av artificiell intelligens som har funnits länge. Användningsområden för artificiella ekosystem innefattar främst biologiska simulationer men även andra typer av simulationer förekommer. Genom att simulera individuella djur blir den artificiella intelligensens uppgift att styra djurens beslut utifrån dess individuella förutsättningar och kamp för överlevnad. Detta arbete behandlar frågeställningen vilken beslutsalgoritm som är bäst lämpad att för att använda till ett artificiellt ekosystem i ett spel. Två beslutsalgoritmer jämförs, en dynamisk som bygger på maskin inlärning och en statisk som inte är kapabel att lära eller minnas.

In this Bachelor's thesis the result from a Delphi study regarding FRBR, performed by Yin Zhang and Athena Salaba in 2007 and published in 2009 ? What is next for Functional Requirements for Bibliographic Records? A Delphi study ? is analyzed by qualitatively interviewing professionals active within the library and information science field in Sweden. The results are compared and possible deviations and adjustments are illuminated and discussed. The purpose of the thesis is to determine the topicality of the Delphi study in 2011 from a Swedish perspective. Conclusions made from the thesis shows that the main areas are still the same, but adjustments regarding the relative order of issues might be needed; primarily a shift of focus from theoretical to practical issues.

The aim of this paper is to investigate who the visitors are at a children's department at amain library in a larger municipality, and for what purpose they use it. We discuss: Is therea difference between various user groups, and if so, how do they differ'? Which library rolesdoes the children's department have? Does the children's department serve as a local libraryfor those who live in the immediate surroundings or as a main library for the whole municipality?The paper is based on a user survey performed in the spring of 1996 at the City Library ofGothenburg. 417 visitors and five staff members were interviewed.The children's department is used by various groups of people, from young children to seniorcitizens. The library roles are, among other things, an independent learning center and formaleducation support center.

The purpose of this paper has been to examine the ways in which professionals describe their work with pregnant drug-addicts. The paper raises the following questions;· How does the deviant behavior, that using drugs during pregnancy can be described as, affect the professionals in their work with pregnant drug-addicts?· How do the professionals experience their own role, and the roles of other professionals?· In what ways do they work in order to reach a favorable result with these clients?The paper is based on qualitative material, gathered through 14 interviews with professionals. By using theories of deviant behavior and attachment-theory between a child and its mother, our intention was to analyze the empirical results.From our interviews we have learned that the professionals consider some factors as more important than others for a favourable result in their work with pregnant drug-addicts. Such factors are for example the significance of a cooperation between different authorities and ethical awareness in meeting with the client..
