The purpose of this thesis is to increase the understanding about consumer buying behaviour when purchasing books online. In order to acquire data for the study we used a questionnaire that 75 students where asked to respond. The respondents were students at the University of Technology in Luleå. Our findings suggest that the following factors are the most commonly cited reasons for deciding to complete the purchase: trust, perceived risk, price, convenience, design of the website and experience. The following factors are the most commonly cited rea-sons for deciding not to complete the purchase: trust, perceived risk, price and the design of the website.

With the development of the Internet, illegal copying of electronic documents has become a growing problem. There is an increasing need of prevention in the field of pirate copying. One method is to mark the document by changing some of the words to synonyms. In this way it is possible to construct legal copies which do not differ in content but still are unique. Since the copies of the documents are unique, it is possible to trace the owner of a document and accordingly call him or her to account for pirate copying if several exactly similar copies are reaching the market.

Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

Att kommunicera förtroende är en nyckelfaktor för att lyckas inom e-handel. Förtroendeinom e-handel påverkas av flera faktorer, där visuell design är en av dessa. Dennauppsats avser att inge fördjupad förståelse för hur den visuella designen spelar roll ianvändarens upplevda förtroende till en e-handelswebbsida. I denna uppsats fokuserarjag på att undersöka hur förändringar av olika grafiska element i en webbsidas visuelladesign påverkar användares upplevda förtroende för webbsidan. För att undersöka dettautfördes flera tester där användare själva fick beskriva sina tankar och åsikter om denvisuella designen och hur de upplevde förtroende till webbsidan baserat på den visuelladesignen och förändringarna av den.

In this day and age we carry out our purchases through different channels. We can shop our clothes and computers in a store or online. Nowadays we can even purchase our groceries through the Internet. The biggest retailer chains within groceries in Sweden have established virtual stores online and are distributing the goods in cities throughout the country. This thesis is dedicated to investigating crucial success factors when going about selling groceries online.

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

Examensarbetet har gått ut på att uppgradera ett styrsystem och en operatörspanel för en centrifug i en kemisk industri. Projektets syfte är att centrifugen ska köras på ett mer automatiskt sätt med ett nyare system som har större tillgång till reservdelar.          Centrifugens äldre styrsystem från Siemens har bytts ut mot ett nytt Siemenssystem och den tidigare operatörspanelen från Siemens har bytts ut mot Beijer Electronic E1070 operatörspanel. Styrsystemet programmerades sedan i Siemens Simatic Step7 och operatörspanelen programmerades i Beijer Electronics E-designer.                Efter att programmeringen var klar testades kommunikationen mellan styrsystemet och operatörspanelen innan inkopplingen av det övriga systemet skedde.

Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

The ever-growing e-commerce brings many opportunities for society's consumers and businesses. Digitization has strongly contributed to these opportunities and has, among other things, facilitated the search for information and increased the range for the customer. While the opportunities are many, the increased consumption has also brought consequences. The increase in consumption contributes, among other things, to quantities of deliveries and returns as well as increased waste, all of which results in environmental destruction. The issue of sustainability is very topical today and is influenced by almost everything today. In connection with the markets changing, the consumers' behaviors and expectations also change.

Brominated flame retardants (BFRs) has for many years been used in products to reduce their flammability, mainly in electronic products, textiles and construction materials. In 2003, Sweden imported 300 tons of brominated flame retardants. Leakage of these compounds has polluted natural environments. Fishes has shown increased contents of these substances, especially fat fish, since brominated flame retardants tends to accumulate in fatty tissues. They are also regarded as persistent and that gives them the ability to travel long distances. What also is really scary is that increased levels of brominated flame retardants have been detected in human breast milk. The knowledge of the brominated flame retardants is limited and not so much research has been done in this field. There are many reasons though, to keep the research going. Partly their structural resemblance to well-known toxics as PCB, but also their ability to accumulate in biological systems and enrich in food chains. In which way they affect humans we really don?t know yet.

Uppsatsen är skriven med utgångspunkt i att understödjande förbands bidrag i operationer i stadsmiljö sällan nämns i reglementen, samt att förståelse för hur telekrigsförband uppträder och deras unika förmågor är generellt sätt låg inom försvarsmakten. Mitt syfte är att tydligöra hur en telekrigsenhet med dess unika förmåga kan bidra till lösande av uppgifter i en MOUT-operation. I min uppsats försöker jag med hjälp av ett teoretiskt synsätt svara på vad en telekrigsenhet kan bidraga med i en operation av ett MOUT-koncept. För att besvara denna fråga använder jag mig av en kvalitativ textanalys och intervjuer. Resultatet som framkommer är att en telekrigsenhet är en unik resurs som kan bidra med unika underrättelser och verkan, främst kopplat till stegen förstå, få bättre lägesuppfattning samt att kunna engagera motståndaren i en MOUT-operation..

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

Speedledger is a company that is working to automate electronic accounting for businesses, organizations and associations.In the current situation bank data is sent from the users internet bank to Speedledger via a virtual printer driver. The driver transforms the web page into a PDF and sends it to a server for interpretation.The problem is that PDF is not created for this sort of data transfer and makes the interpretation of data is very problematic.The goal of the thesis is to study whether there is a possibility to develop a browser add-on that can retrieve information on the customer's banking page and send it on to Speedledgers server for interpretation. My task was to implement a add-on for one of the three major browsers Mozilla Firefox, Google Chrome or Microsoft Internet Explorer, and then study the possibility of implementing it to the other two by reading the documentation.What I concluded was that it is possible to implement for all the three browsers. However, the techniques will differ slightly when developing these add-ons.  .

En snabb och ständig teknisk utveckling leder till att företag och andra organisationer kan ta del av nya tekniska verktyg, som sedan kan användas i verksamheten. Till följd av detta möjliggörs nya sätt att kommunicera information och göra affärer på elektroniskt. Detta område kallas elektroniska affärer och får allt större utrymme idag, men vad är det egentligen som gör att ett företag intresserar sig för det?Elektroniska affärer är ett stort och komplext område som ofta kan innebära stora förändringar för ett företag. Att eventuellt strukturera om och förändra arbetssättet kan vara något som ses som lite skrämmande för en del företag och därför kan det uppstå problem med att se de positiva effekterna.
