Implementering av ISOBUS Virtual Terminal på fordonsdatorn CCP XS
Modern agriculture equipment are more computer based today, and many equipments use a terminal in the tractor where the driver have the opportunity to make adjustments to the equipment. This is the reason why ISO developed a new standard called ISOBUS. It is a communication standard based on CAN specially adapted for griculture equipments. The purpose of the standard is that it should be ossible to equip a tractor with a standard terminal called Virtual Terminal that can be used to control the equipment. The use of the terminal should be independent of the manufacturer of the tractor as well as of the equipment.The purpose of this report is to ?nd a solution of how to use CC Systems on-board computer, CCP XS, as a Virtual Terminal.
Analys av datakommunikationssäkerhet för VoIP-protokoll
Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..
Det moderna biblioteket: Om biblioteks marknadsföring i sociala medier
The aim of this thesis is to investigate how libraries market themselves in social media and why they do it. I have studied a certain public library?s process of introducing social media into its marketing mix, the preparations for this process and the effects of these marketing methods.The theoretical framework for this thesis is based on relationship marketing, a theory which focuses on relationships, networks and interaction. My main method has been semi-structured interviews with a librarian at the relevant library, with the manager of the library and with the head of the municipality?s department of communication.The results of my studies show that marketing on social media is a positive and important thing for libraries.
Vem ser barnet? : En kvalitativ studie om psykosocialt stöd till familjen när en förälder lider av en livshotande sjukdom
The purpose of this study has been to investigate how psychosocial support for families where a parent suffers from a life threatening illness can be constructed. The intent was also to explore how the child's perspective is protected and what barriers and opportunities there are for family oriented support. The study has a qualitative approach and includes interviews with four social workers. The interviews were analyzed with a systems theory and attachment theory. The conclusions are that the whole family suffers psychological and social pressures when a parent is sick.
Politecast : ett nytt kommunikationsprimitiv för trådlösa sensornätverk
Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.
HAVECA-modellen - En metod för att fortlöpande säkra ett internt nätverk mot tredjepart
This thesis will address a problem concerning availability of information
systems at an enterprise within the financial sector and its external
suppliers, so called trusted third party. The information system resides on the
internal network of the enterprise and must be available to both employees of
the enterprise and the trusted third party simultaneously. This contradicts the
company policy which
disallows third parties access to the internal network. The HAVECA-model
introduced in this thesis provides a framework of methods, each solving a sub
problem identified in the model. The identified methods are hardening,
verification, control and assurance, together supplying a method for
continuously securing the internal network against a trusted third party.
Politiska mord- en rättfärdig strategi i kriget mot terrorismen?
After the 9/11 attack the United States declared war against terrorism, which launched a conflict between indefinable transnational networks and states. In this war it became clear that the strategies used in traditional wars between states were not sufficient. New strategies have been discussed, but without any concrete results.In this thesis assassinations of terrorist leaders ordered by states is being presented as a possible strategy in the war against terrorism. Assassinations have been used in all times to shift political power but is today not morally accepted. This thesis aims to show that when used under the premisses of the just war theory, the strategy can be equally morally justified as any traditional war.
Logistiska lösningar för en lönsam byggprocess
This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.
Bluetooth and security
Detta arbete behandlar hur Bluetooth fungerar samt säkerheten kring Bluetooth
och några allmänt tillgängliga attack verktyg.
Syftet med uppsatsen är att försöka fastställa hur säkert Bluetooth är i dagens
läge. Bluetooth har länge varit tillgängligt för att utbyta data över korta
avstånd. Därför har man valt att implementera det i kommunikationsenheter som
mobiltelefoner och laptops med mera. Det har funnits en debatt om hur säkert
Bluetooth är. För att kunna genomföra denna undersökning så har vi satt oss in
i hur Bluetooth fungerar, vilka allmänt tillgängliga attacker och
implementationer av dessa, som finns.
Demokrati och diskurs. En normativ analys av diskursiv påverkan på de demokratiska värdena öppenhet, ansvarsutkrävande och inflytande
The idea that I put forward in this thesis concerns the democratic system and the threat from discoursive impact on its core values. I focus my normative analysis on three of these democratic values: transparency, accountability and influence ? and what democratic problems the discoursive impact causes in conflict with them. I have used a critical discourse theory to define discourse and discoursive impact, by focusing on the process of discourse, rather than its nature. I deal with the political structure where I claim that the essential relation between citizen and politician is disrupted, due to lack of information and the imminent problems of the existing network society.
Smarta Hus: Nya behov och lösningar med participativ design
In this Bachelor Thesis (20 p.), we present the history and development of
"Intelligent Houses", and most important- explore some of the future
possibilities in this area.
The project has been carried out through an interdisciplinary cooperation
between three different educations at the Blekinge Institute of Technology.
By conducting a dialogue with various actors with different professions, we
have been trying to identify needs within the concept of "Intelligent Houses",
were the end user is not only the tenant or homeowner.
Through Participatory Design methods, such as a Future Workshop, we have
brought the users together to discuss their own and each others needs and
hindrances in their respective work practice, and how intelligent house
technology could improve their work conditions.
We have also been testing a highly sophisticated
CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally
developed for regulating indoor climate systems.
Based on the needs we have found in our fieldwork, we have been looking at
possibilities to make multi user solutions with the sensor..
?Att få fler att upptäcka det fantastiska med läsning? - Möjligheter och hinder för samarbete mellan bibliotekarier och bokbloggare
The aim of this bachelor thesis is to find out the possibilities for librarians and book bloggers to collaborate. We find this relevant because of blogs being a new medium that could be useful for librarians to embrace. Book blogs are often networks of blogs connected to each other through their common interest in literature and we have examined how this could be of use for librarians.The method we have used is semi-structured interviews, which gave us the possibility to adjust our questions based on the informants? answers, when necessary. Our informants have been both librarians and book bloggers; we have met some of them and interviewed the others by e-mail.
Athena - En intelligent och flexibel säkerhetslösning för transportbranschen
The project team has chosen to carry out the project itself. This is to be able to work more flexibly in the product development process and not be guided by some guidelines.Every day, we read in the media about a new truck burglary. The problem has become so common that we do not even notice it in the media. Each year the theft of 1 billion of Sweden and the entire 82 billion in Europe in 2008. This is an increase of 10 billion by 2007.
Rätt kvalitet? -En nulägesanalys av byggbranschen
The purpose of this Master?s thesis is to study how university teachers look upon information literacy, what they consider the professional role of the academic librarian and how they value cooperation between the two professions. The methodology is based on qualitative interviews and is inspired by phenomenography. A limited number of qualitative interviews has been carried out in order to describe the attitudes and opinions of the university teachers related to my issue. I have also used the results of two theoreticians, Monica Hansen and Berth Danermark, who have studied cooperation between different professional groups.
Icke-triviala billigaste väg-ruttningskonflikter - klassificering och sökmetoder
Within telecommunication and routing of tra?c in IP-networks a protocol named?Open Shortest Path First? (OSPF) is widely used. This means that a server dealswith the routing over a network with given weights by calculating shortest paths touse for routing. If we assume that a desired tra?c pattern is given the problem isto ?nd out if it is possible to set the weights so that the desired tra?c pattern is apart of a shortest path graph.
