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.

Websites today only offer simpler form of technical analysis and are not fun to use, therefore student decided to build a website that makes technical analysis a bit more fun by giving user possibility to experiment with settings for technical indicators and also see clear visible results from analysis. Student decided to build website in ASP.NET. Technical indicators for this project only consist of those who give buy and sell-signals via cross-over, no divergence or pattern finding.This project has three questions that define this project. It?s important that there is good functionality so that performing an analysis is perceived as simple, one question is therefore; what functionality for website is needed in order for analysis to be perceived as more simple?Technical analysis is a pretty complex subject and demands an interface that is perceived as easy to understand and easy to use, it?s therefore important that the interface is well designed, second question is therefore; how should the interface be designed to be user-friendly?When systems grow large they often become hard to develop and later on unmaintainable because of the accumulated complexity and dependency between classes, the code is a mess, the last question is therefore; how can the systems complexity be eased with object-oriented design principles?Jakob Nielsens ten heuristics for User Interface Design were used as inspiration for designing the interface for the website.

This thesis is based on design theory about how to build an application for the mobile platform, a scientific analysis and an application for grocery shopping and meal planning. The thesis also contains a valuation of the research and of the application. The valuation of the application was done by a usability test and an analysis of the results of the test.The application of the thesis has an easy navigation system, which is time saving and simple to use. Finding recipes with the associated ingredients is a quick fix. The search function can be used for searching freely after recipes as well as for separate ingredients. That makes it possible for the user to create own recipes from available ingredients.

Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.

In this qualitative user evaluation, users from the Krami-programme in Borla?nge have been interviewed on what they consider to have been positive changes in their social situation after participating in the programme. The respondents also point out factors in the programme that have supported these changes. The method consisted of interviews with five men who have undergone the Krami programme.The results show that Krami primarily helps the users to get an employment which results in the repeal of criminogenic factors. This plays an important part in the positive change of the users self-esteem, which tends to lead towards ?unlabeling? of the individual as ?criminal?.The study also indicates other factors in the program that the users found helpful in their process of change highlighting the interaction between authorities, the approach of the Krami- staff and also the common rules that the participants has to agree upon.

The purpose of this paper has been to study how users experiences and behaviors are influenced by a "like" function, when publication of images in social media with the photo app Instagram as the selected base. In this study respondents has been part of a study regarding their experiences and behavior related to "like" function in Instagram. The results of the question form have then been analyzed to find patterns in their behavior and to exemplify/reinforce different type of user-behavior found in related scientific articles.The study has shown that the behavior of Instagram users is affected by the "like" function, when they believes that the function is a status marker that raises the interest for certain users by the number of likes. Through my results, I have been able to amplify and illustrate several theories of Goffman, Buckingham and Gripsrud which are presented in the report..

The aim of this Master?s thesis is to examine how librarians in a Swedish public library view and discuss mediation of fiction. The questions posed in this study are: How do the librarians want to work with mediation of fiction? What type of literature should be provided according to them? How do they express that they relate and should relate to their users? The theoretical starting-points are three categories extracted from Jofrid Karner Smidt?s doctor?s dissertation Mellom elite og publikum: the approach to users, strategies for mediation, and ideals for mediation. The empirical material was gathered through focus group interviews with librarians in a public library.

This degree project has been done in parallel to the advertising agency Hera in Uppsala, and containsthe creating of a logotype and graphic profile for Aircall, a new big chain of shops dealing with telecommunication.Aircall was found 1 February 2004, when three smaller companies became one. Thisnew company were in need of a common brand and a uniform profile. The created graphic profile hasbeen applied to visiting cards, letterhead, envelopes, letter cards, bags, cars and advertisement. Thegraphic profile has also been used when designing the shop interior end exterior. Research has beendone on competitors graphic profiles and advertisement.

The purpose of this thesis is to investigate how city librariesmaintain the intellectual freedom in their Internet service. Thediscussion about Internet filters has been quiet in Sweden forseveral years, so I wanted to see if there had been an increased useof filters. I also wanted to see if the city libraries regulated theInternet service in another way. I sent a survey to 100 libraries andgot answer from 83. To explain what intellectual freedom is, I usedStuart Hamilton?s theory about intellectual freedom in the librarycontext.

Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

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..

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.
