With a new digital world that runs parallel with our physical one, we are also facing a new type of architecture and new materials that this new architecture is built on. In this thesis I examine pixels and vectors, two of the digital materials used to create pictures. By approaching them as digital materials, I have mapped their different qualities, when and where one or the other is more or less applicable and the reason behind it. My main research question asked was the following: Are the (digital) materials challenged outside their primary fields of application, and in that case, in which way? With this question in mind, I carried out a semiotic picture analysis on four pictures, later on dividing them into four different categories, based on their different qualities and their ability to deliver information.

Through geopolitical theory this thesis explores how conflicts within states can be read and understood according to an analytical model determining one or several possible causes for the conflict.  The model is created by the author and reflects geopolitical theory by giving three possible explanations to an intrastate conflict: culture, economy or territorial construction. The aim of the thesis is testing this model on two selectively chosen case studies ? i.e. two intrastate conflicts ? namely: the upcoming referendum in Scotland and the terror attack at Tiananmen Square in China.

Firewalls protect network traffic and decide witch traffic to send further and witch traffic will be blocked. All this depends on the rules in the firewall. The firewall is installed between the internal network and the Internet. It is difficult to find a firewall that can protect us against different threats. Firewalls have both advantages and disadvantages and all this make them vulnerable.

I examine how relationships between people and objects are created and continues through contiguity every time one use or touch an object and through participation through use and memories. The aim is to continue a relationship and to keep a communication alive with people beyond time and space, then, now and henceforth. I take advantage of and transform the traces in an object that belonged to someone. Parallel I create new space for bodies to put their mark for the first time. I compare my work with the Nordic Museum's task to preserve the present for the future.

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

In modern leadership research, leadership is often viewed as a social construction, and under this paradigm various researchers let the media play a central role in constructing leadership. Meanwhile, the question of how the media actors do this is left unanswered. We explore the question of how and why the media construct leadership, from the vantage point of the media actors themselves, and the conditions they work under. Different mechanisms for media construction of leadership are identified in previous research. Through interviews with business journalists at Veckans Affärer, we find recognition for some of the explanatory mechanisms: namely that personification of a CEO facilitates the work of journalists (and sells papers), that personal drama captures reader demand, and that the CEO of a listed company consciously cultivates his or her personal parallel self.

Syftet med detta examensarbete var att undersöka vilka behov och upplevelser av stöd personer som drabbats av hjärtinfarkt och deras närstående har. En litteraturstudie har genomförts, vilket har inneburit granskning och sammanvägning av resultat från vetenskapliga publikationer. Resultatet visar att personer som drabbats av hjärtinfarkt och deras närstående har stort behov av information, psykosocialt stöd och tillgänglighet av hälso- och sjukvårdspersonal. Det behovs fortfarande forskning kring personer som drabbats av hjärtinfarkt och deras närståendes behov av stöd speciellt ur ett genusperspektiv. Framförallt finns kunskapsbrist om hjärtinfarktens inverkan på relationen då en man förväntas vårda sin hustru.

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.

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.

This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering.  To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.

The SK 60 Aircraft has been a workhorse for the Air Force?s training of future pilots since the late 1960s. The aging SK60 aircraft is going out of style, and the system has merely a few years of total running time left. A replacement for the SK 60 needs to be implemented in the coming years, and the Armes Forces Flying School has been commissioned to conduct flight tests on suitable replacement systems. This study will conduct a system analysis of two aircrafts mentioned in the Flying Schools report.

John A Warden III har en teori om hur luftkrig ska genomföras, som sedan slutet på 80-talet influerat bland annat USA i deras planering och genomförande av luftoperationer. Denna teori var som mest aktuell under Gulfkriget 1990-1991, där luftstridskrafterna genom ett agerade enligt Wardens teori gav stora effekter på konfliken.Detta arbete syftar mot att undersöka om Wardens teori fortfarande används, och vilka effekter detta agerande medför. Arbetet presenterar de begrepp som kan ses som centrala i Wardens teori och analyserar dessa mot en fallstudie som rör flygstridskrafternas agerande under inledningen av Operation Enduring Freedom i Afghanistan år 2001.Slutsatsen är att det finns spårbarhet av Wardens tankar om luftöverlägsenhet under hela perioden som arbetet berör. Däremot finns det endast spårbarhet av att koalitionen agerade enligt tyngdpunktsbegreppet, parallell attack och fienden som ett system under den inledande fasen av konflikten. Därför kan det inte sägas att koalitionen agerade enligt Wardens teori under konflikten..

Mergers and acquisitions are common phenomenon in today´s society in order to increase shareholder value. Two years ago a fusion of Sweden´s two largest companies in the industry of real estate took place and even though three out of four mergers and acquisitions financially fail this certain case turned out highly successful. The aim of this thesis is to examine how the organizational structure and the management control have been designed and characterized the organizational performance and furthermore what are the success factors of the integration. By studying an acquisition and its potential effects on organizational structure and management control parallel to a model that describes the best practice guidelines for managers to successfully deliver value from their acquisitions, it can be shown that an acquisition has direct effects both on the acquirer and the acquired company and thus the new organizational structure. The main results, thus, is that through active leadership, increased specialization, and more decentralized and thus efficient management control a new organization has emerged consisting of the best features of two separate worlds..

Från oktober 2006 till juni 2007 genomfördes en rad attacker i Irak där man använde bilbomber lastade med klorgasbehållare. Hundratals människor exponerades för gasen och attackerna fick stora konsekvenser för koalitionens agerande.Denna uppsats granskar attackerna för att analysera de krav som ställdes på aktören som genomförde dem. Därefter appliceras kraven på den motståndare som Sveriges insats i Afghanistan möter för att belysa hotbilden för svenska enheter att bli utsatta för en liknande attack. Vidare beskrivs de konsekvenser som hotbilden får för insatsen.Resultatet av undersökningen visar att motståndaren i Afghanistan skulle kunna genomföra en klorgasattack om denne uppfyller vissa kriterier som rimligen skulle kunna uppfyllas. Konsekvenserna för den svenska insatsen är att man, om möjligt, bör undersöka motståndarens kvalitativa kapacitet kopplat mot klorgasens användande, övervaka flödet av klorgas i sitt operationsområde samt öva grundläggande soldatfärdigheter för självskydd..
