The security solutions used in wireless home networks are examined in this report. Thegrowing number of wireless units have increased the need for reliable security solutions.This report aims to enlighten the reader about the fundamental technology used inwireless security solutions and inform about the existing flaws. A recommendationabout how to achieve a high level of security in the home network is also given to thereader.Several flaws in the security solutions in use have been reported. Of these the mostsevere has been examined in a test network using highly accessible tools to get aperception of how vulnerable the user is.The tests showed that several attacks were efficient and easily carried out. We have alsoseen that several of the home networks in our sample are susceptible to these attacks.Our survey revealed that the Internet service provider's technical support in many caseslacked the knowledge necessary to inform the user about reliable security solutions..

The purpose of this work is to providing a general set of base classes for building simulators, for example a robot system. Instead of every time building a new simulator from the beginning, you get the already completed components from a library. The library should in that way act as a springboard for development.To do this work, there?s a lot of knowledge required in how a general robot system could look like. Therefore it was necessary to gather some information about robotics.

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.

To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.

During recent years, the labor market has changed. Social media currently plays a larger role within recruitment for both job seekers and employers, while company policies and routines addressing background checks become less strict. The result of these changes are higher demands upon social media users to censure their online image. This study focuses on LinkedIn, which is a website intended to provide users with tools for career development. The study is aimed at user interaction with LinkedIn and how this interaction can influence career development.

The purpose of this bachelor thesis is to examine reviewswritten by users in library online catalogs, online bookstoresand on the web community LibraryThing, in order todetermine whether there are any differences in the way usersreview books, and whether these differences might explainwhy libraries experience difficulties in getting their users toreview books. At the core of web 2.0 and library 2.0concepts lies the thought of user participation, and largerlibraries have sought to implement systems for reviewingand tagging items in the catalog in ways similar to onlinebookstores and other websites.By analyzing the contents of user reviews, however, thisthesis shows that users express themselves differentlydepending on what kinds of literature they review, and inwhat context. Most notably, user reviews of ?the Classics? orcanonized literature recognizes the high status of suchliterature, while users reviewing popular fiction expressthemselves in a way that admits that the reviewed titles areconsidered less valuable. There are also signs that booksreviewed at online bookstores are seen as products ormerchandise, while the reviews at the library to a greaterdegree treat the books as works of literature.The conclusion reached in this thesis suggests that there maybe a relation between the image of the library as a defenderof high culture and the perceived status of literary works,causing users to become hesitant to review books, feelingthat they do not have the knowledge to describe or reviewthem ?correctly?..

Utvecklingen av informationssystem har de senaste åren gått framåt med stora steg. Trots detta utvecklas massvis med informationssystem som inte fungerar i verksamheten där de ska användas. Detta tillsammans med ökningen av användandet har gjort att kraven på systemens utformning har stigit. Många författare anser att lösningen på detta är att engagera användarna i större omfattning än vad som görs i dagens utvecklingsmetoder. En av de mest använda metoderna för systemutveckling idag är Rational Unified Process (RUP).

This thesis aims to discuss how an information system and its users may adapt to each other. The main discussion is how to create an information system that is adaptable without losing its organising properties. The thesis uses a holistic approach to the topic and the areas being dealt with are information architecture, interactive information retrieval and information searching. The practical work consisted of constructing a database for Autoliv?s Research and Development branch.

In relation to the development of IT-products it is very important that the software supplier is aware not only of the target group but also the field of application. Usability should characterize the whole IT-design process as, in relation to this context, design includes more than merely those aspects which are visible to and thus can be interpreted by the naked eye. The study examines the specific qualities and properties that substantiate the usability and the demands that a customer rightfully expects from an IT-product. The user and the customer are highlighted in the same context in order to demonstrate that it is through the customer that an IT-product is defined as being useful. Thus, from this perspective, the user and customer can be considered as being the same person.

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.

Without being aware of it, cognitive processes continuously take place in our heads. We are forced to fill in the information gaps that we meet in our everyday life in order to create an understanding and to form a whole, and that?s where the importance of inference comes in. To create inference implies creating meaning from something that is not explicitly given. Having knowledge about this process offers great possibilities, while not taking it into account may involve risks.

Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased. As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.

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.
