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.

Bibliotekariens nya arbetsmarknad

The purpose of this thesis is to examine why graduates in librarian- and information science are employed by private companies. An initial explanation could be the influence of information technology and its impact on the librarian. A second factor relates to how employers regard the librarian outside the confines of the traditional labour market. The study is primarily based upon qualitative interviews with representatives of Swedish companies who have employed librarians since 1993, the year that the education achieved third level academic recognition. Theoretically we relied upon Manuel Castells discussion on the rise of the information society and its influence on companies and the labour market.

Aktiv bullerdämpning i ventilationssystem

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Jämförelse av tjänstgöringsbestämmelser i BCL-D och EU-OPS : En fallstudie för West Air Sweden

För ett flygbolag är det viktigt att ha en effektiv planering av sina resurser. Att kunna utnyttja personal och flygplan på rätt sätt är en förutsättning för en fortsatt överlevnad på marknaden. Flygbolagens tjänstebestämmelser regleras idag enligt nuvarande BCL-D 1.15. Under våren 2004 har Luftfartsverket behandlat en remiss som utgör ett förslag på en eventuell förändring av dessa tjänstebestämmelser. Remissen är ett förslag som skall gälla det gemensamma regelverket EU-OPS.

Enskild väg till Tolleredsskog

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

Utveckling av minimax-baserad agent för strategispelet Stratego

Stratego is a boardgame not very different from chess, that contains hidden information. Because of this, existing programs play at beginner level. The purpose of this thesis is to adjust a minimax algorithm so that it passes the demands of Stratego, and then build a Stratego agent around it. Tests with existing minimax algorithms leads to the development p-e-minimax. This algorithm uses two different values in its nodes to simulate the different information available to the agent and its opponent.

Den Digitala teknikens påverkan på resebranschen och dess marknadsföring

The intention of this essay has been to investigate how the new digital technology has affected the tourism industry and marketing, as well as how travel agents and tour operators adapt to this. We also aimed to get a broader view of how the future might look like when it comes to marketing and virtual service landscapes. We decided to base our research according to these following four questions:? What affect travel agents? way of adoption to the technical development?? What purposes do the travel agents have for building up their virtual service landscape?? How much does the travel agents emphasize on digital marketing?? What can travel agents do to better adapt to the technological development in the future?We have chosen to use a qualitative research for this essay. The reason for choosing a qualitative research was to gain a wider understanding that would represent a big part of the changes of technology development.

Nätverk i nätverk : en nätverksansats i den nya ekonomin

Society and technology develop together in interaction processes. Because of the development of information technology, the Industrial society has been left behind in favor of a society where information is the key production factor, i.e. the Information society. In the Information society, social functions and processes are organized in networks. These networks integrate geographically separate markets to parts of a complex global economic system.

Systemutveckling med fokus på kreativa processer och lärande

Med denna uppsats vill vi (författarna) samla ihop 5 år av tankar, teorier och erfarenheter kring systemutveckling och lärande. Uppsatsen presenterar 8 projekt som är genomförda i Blekinge mellan 1995-1999. Med utgångspunkt i projekten behandlas en utvecklingsprocess för IT-system som är baserad på kreativitet och lärande miljöer. Särskilt lyfter uupsatsen fram behovet av att förändra processen för att möta slutanvändare av program och tjänster..

Bibliotekscheferna och bibliotekarieutbildningen. En enkätundersökning av bibliotekschefers syn på utbildningen i biblioteks- och informationsvetenskap i Sverige

The aim of this thesis is to investigate what chief librarians in Sweden know about the present education in Library and Information Science and what opinions they have of it. We have used the following four questions as a starting point for our work: + How much do the chief librarians know about the education in Library and Information Science? + What are their opinions of the education? + What emphasis do they put on academic degrees and practical experience? + Are there any differences between various kinds of libraries regarding these issues? We decided to use questionnaires to gather our information. These were sent to 200 chief librarians on both public and research libraries all over Sweden. 151 of the questionnaires were answered.

Tobaksrökning : Hälsa eller ekonomi, en uppsats om tobaksproblematikens olika aspekter

Uppsatsen strävar efter att undersöka och belysa den problematik som präglar den svenska tobakspolitiken. Jag har identifierat tre centrala frågeställningar:* Vad utgörs det strukturella problemet av?* Vad gör lagstiftaren respektive tillämparen?* Hur manövrerar lagstiftaren för att undvika politiska kostnader och till synes lösa det strukturella problemet?(utdrag ur uppsatsens "Frågeställning och syfte").

Mersault eller Meursault? : En komparativ studie av två översättningar av Albert Camus Främlingen

The ever-evolving information technology gives users more opportunities, but also put higher demands on them. The digital agenda of the state and society clarifies the objectives and effects academic libraries? development. E-books influence the development of organizational, economic, legal and political perspectives. At the University Library in Gävle work is ongoing. The process is controlled by the acquisition policy which makes it clear that e-books should be purchased if possible.
