Computers together with Internet have been growing enormously, during the last decade and the area of information technology has been growing in the same speed. As long as the surrounding environment evolves, the business models must within the IT-area, keep the same pace. So, how do business corporations handle this change to attract customers? How do the dominant business models look like? In many cases, they are apparently much the same. But what differences can we see and what areas can be improved? We have showed that the IT area isn?t just one, it consist of several segments.

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

I detta examensarbete har en studie genomförts av hur väl 3D-skrivning kan tillämpas i Volvo Cars i Skövdes produktion. En litteraturstudie har genomförts för att åskådliggöra de olika 3D-skrivningsteknikerna och deras användningsområde. För att på ett överskådligt sätt jämföra de olika teknikernas duglighet har en bedömningsskala utvecklad av Nasa använts. Denna skala benämns som Technology Readiness Level (TRL). Den teknik som bedöms som mest lämplig med avseende på fullskalig produktion samt prototyptillverkning är Selective laser melting (SLM).För att åskådliggöra fördelar med 3D-skrivare har en förenklad 3D-modell av Volvos cylinderblock I5D modellerats.

The purpose of this paper is to find out how visually impaired people get information on Internet. Visually impaired people has got the right to be able to use the Internet like everyone else. We are also going to revise which aids visually impaired people use today, and how they work in practise. What problems can you run into when you use these aids? We are also going to revise how the webpages design affect the use of the Internet for the visually impaired people.

This study is a comparative study of the occurrence and function of information literacy in the curricula of the Swedish and Bavarian Gymnasium and investigates the occurrence of the term ?information literacy? and shows through what other linguistic means the notion of information literacy is expressed in the curricula. The study also wishes to analyze how the notion of information literacy manifests itself in the different school systems. Relevant textual passages of both curricula are compared to each other through the theoretic lens of Bruce?s phenomenographic model of information literacy.

The purpose of this study was to examine and compare what six preschool teachers thought about their opportunities to take advantage of children's interest in natural sciences and technology, across four kindergartens. The following questions were explored in order to achieve the aim of the study: How do the preschool teachers interviewed describe their work with science and technology in the preschool and what these preschool teachers think about the meaning of motivation in the children?s learning of natural sciences and technology in preschool.  The study used a qualitative approach in the form of semi-structured interviews and interviewed a total of six trained pre-school teachers from four kindergartens with different profiles. The first kindergarten focuses on mathematics, science and technology.

The purpose of this Master?s Thesis is to examine and describe how a wiki can be used in the information seeking education. We believe that the preconditions for education and learning are changing; technology and Internet has introduced new tools for the learning situation. To examine this we will describe how the wiki technology can be used in the information seeking education, describe how the goals of the information seeking education are reached when using a wiki and lastly investigate the school librarian?s pedagogical role in wiki-based education.

The automotive industry is today in a world of globalisation and external factors can influence the car companies and it is important that they progress with the people. When an external factor, as the oil price, increases dramatically, it will affect the economies in different matters. Other external factors are impacted by the oil price, for example inflation, unemployment and target rates. In addition, people are changing their preferences due to the attention of the environment. With this as the foundation the problem of the essay were divided into three aspects.

The notion of firms interacting with technology is not new; these types of systems were already in place in the mid eighties. E-business users worked with connections between their inbound logistics and procurement systems, and suppliers? order-entry systems. When these connections were described for the first time the vertical links between two, or more, value chains in a value system received more attention in firm strategy. The design of the linkages in the value system was said to be a product of the need for coordination and relative bargaining power.

Information Technology (IT) makes it possible to electronically distribute data between actorswho are in geographically diverse areas. Nowadays, information is sent less frequently throughtraditional correspondence in favor of faster electronic equivalents via the internet.Despite effective IT environmentand secure encryption techniques choose some actors to sendinformation through physical delivery. This phenomenon occurs in those working withconfidential information as it is handled by a number of rules and safety regulations.Based on a set of rules and requirements, we have looked over the possibility of sending sensitiveinformation electronically over the internet. The aim was to find general guidelines for howcompanies and organizations should manage and send sensitive information over insecurenetworks. This led us to our research question: How can information be exchanged betweenactors in geographically diverse areas be categorized and encrypted so that it can be transportedover the internet without security or integrity deficiencies?To answer the question, there was a case study at a defense company.

Information about the risks involved shall be distributed to the people living in the area nearby to potentially dangerous installation. Swedish law stipulates strict requirements on what information should be supplied, but the law itself does not give any guidance on presentation. The main purpose of the study is to give recommendations on how to improve the information brochures. Within the study, eight people working with risk information have been interviewed and seven different risk information brochures have been studied. Also, a theoretical analysis and a practical experiment were performed using brochures from two municipalities.

The purpose of this master thesis is to present a model that illuminates the important factors when deriving technical information from market data within a company. For companies to be able to become and stay competitive in the market, product quality is an important factor. Whilst good product quality leads to customer satisfaction and loyalty, lack of quality brings costs in service and replacements. To improve product quality, the developers need information and knowledge about what quality issues affect existing products. Most companies gather data from market about known issues, but in order eliminate known quality issues in new products; this data has to be transformed into information and knowledge.

This exam paper has been a collaboration between the writers and SYSteam Utvecklingspartner in Huskvarna. The assignment was about finding a need for a mobile application, making a requirement specification document with design documents and parallel to this constructing a prototype. The assignment is summarized in the following questions:? How can companies in the forest industry benefit from mobile information technology?? How can a user centered perspective be used in the process of making the requirement specification document and the design documents?? How do guidelines for usability apply to a mobile application?Three visits to companies in the forest industry were made to find a need for mobile information technology solutions. After a small analysis of the different companies? problems and conditions the decision was to use Tenhults Impregneringsverk AB in the case study.We used the FA/SIM method in our job of finding the organization needs for change and the principles of User Centered Design in the work of constructing a prototype.The result of our work is a requirement specification with design documents and a prototype.
