Intranät är idag verklighet för många organisationer. Dessa system växte fram någon gång under 90-talet och finns idag i nästan alla större organisationer. Dessa system har dock inte utvecklats i samma takt som Internet. Det beror på att intranät är mer kontrollerade och inte utvecklas naturligt utan beslut ifrån organisationens ledning. Samtidigt växer Webb 2.0 sig starkt på Internet.

Denna rapport tar upp hur ett par olika programvaror, nämligen Packet Tracer och GNS3 kan användas för att simulera verklig utrustning i syftet att använda dessa hos ett företag i labbmiljö för att förbereda en implementation av ny hårdvara samtidigt som kostnaderna kan hållas nere, men också hur dessa programvaror kan användas i studiesyfte och använda som komplement till fysisk utrustning inför laborationer och examinationer i de olika kurserna som Cisco erbjuder. Det är också en utvärdering för att avgöra vilken av programvarorna som är den bästa att använda. En topologi sätts upp, komplett med IP-adressering med relativt vanlig konfiguration för att se hur dessa programvaror hanterar och klarar av dessa konfigurationer. Det visar sig att båda programvarorna presterar bra i de flesta fall, men de avbildningar av IOS som testats i GNS3 saknar stöd för PortSecurity som standard, så Packet Tracer tar titeln. Packet Tracer lämpar sig bäst för grundläggande studier med sina enkla paketspårningar medan GNS3 fungerar bättre för mer avancerade topologier med möjlighet till import av befintlig hårdvara.Nyckelord:  Cisco, Packet Tracer, GNS3, Simulering..

The implementation of IFRS 2 led to significant changes in the accounting practices for corporations regarding stock related compensation. The new regulations required firms to account for the stock based compensation as an expense in the financial statements, rather than merely disclosing the information in the notes section to the statements. Following prior research on the area; specifically studies made in the U.S., where researchers find that companies change their use of stock based compensation due to the increased accounted expenses, this study hypothesizes that the same pattern may be found among companies listed on the Swedish stock market. The results of this study show that the use of option incentives has decreased during the studied period 2001-2008 and that the decrease in part can be derived from IFRS 2 and in part from other factors. The results are useful to future research, as they provide an overview of the effects that IFRS 2 had on companies, and various factors that influence the behavior of corporations, as well as in a larger perspective be a factor to take into account for future modifications of the IFRS..

Real options analysis is a method for assigning value to flexibility in decisions, coming from uncertainty in future outcomes. This thesis ascertains to what degree this method is superior to traditional net present value analysis, with regards to ease of implementation in relation to the benefits from being able to measure the total value. Real options analysis is evaluated with a case study of the Swedish online gambling market, and conducted with the binomial framework of Copeland and Antikarov (2003). The authors find the sensible use of real options dependant on the specific situation to which it is applied, i.e. a certain degree of future uncertainty and managerial flexibility is necessary for justification of the increased workload.

The major part of the existing research on psychological effects on participating in war or residing in a war zone shows negative effects on the person?s mental health. However not all research, from an international perspective, shows the same results. Since we haven?t found any research regarding Swedish conditions and there has been a recent implementation of a decision from the Supreme Commander regarding commanded international service for all staff within the Swedish armed forces, the question has now become more relevant.

By studying literature concerning design, didactics and reflection, and complementing those explorations with interviews with experienced design educators, this thesis challenges the idea of aesthetic media education being purely aesthetic in its characteristics. Drawing from their own experiences as a media aesthetics educator and an industrial designer, the two authors argue that the work flow used within most fields of design, commonly known as the design process, might provide a suitable didactic alternative to a field of education lacking relevant methodology. The literature study offers a better understanding of the design process and how it may be defined and viewed within an educational context. The interviews provide a more practical insight into the world of design education. The result shows that the design process as a didactical method theoretically offers both elements of critical thinking as well as direction and frames for students lacking aesthetic and artistic experience.

Denna uppsats har haft examensarbetet ?MPLS kontra traditionell IP-routing - enjämförelse av resursåtgång? av Sebastian Viking och Anton Öhlin som stöd. Derasarbete jämförde processoranvändning vid routing med, respektive utan, MPLS.Resultatet påvisade att MPLS gav högre processorbelastning gentemot traditionell IProuting,tvärtemot vad teorin för MPLS säger. På grund av uppenbara motsägelsermellan teori och praktik ämnade detta arbete skapa en hypotes som undersöks deduktivtmed målet att bekräfta dess utsaga: På grund av MPLS, respektive IP:s implementation iunderliggande hårdvaruarkitektur, kommer ingen märkbar skillnad iprocessorbelastning att uppvisas vid tester där en routers uppgift är att förmedla paket.Vi har därför återskapat deras tester för att verifiera äktheten i deras resultat. Resultetfrån våra egna tester visade ingen uppenbar olikhet mellan routingteknikerna IP medCEF, respektive MPLS.

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

The Swedish government has set up 16 environmental goals for Sweden to achieve. One ofthem is ?Living forests?, which is the foundation for the ?National strategy for the formalprotection of forests?. The ?National strategy? puts the private forest owner at the centre ofattention in order to achieve the environmental goal ?Living forests?.

The history of books and libraries in the Philippines starts after the arrival of the Spaniards in 1521. During the Spanish era, most of the libraries were established through the religious orders to support their own religious mission. The Americans came in the beginning of the 20th century and have had a decisive influence on the education system and the development of libraries in the Philippines. For the analysis, I have used the models of Michael H. Harris and Magnus Torstensson in their studies of library development.

Gränssnitt finns överallt i vår vardag. Du finner dem i hemmet, i biblioteket, i affären, på tågstationen och till och med i din ficka. Hur kan utvecklingen av ett gränssnitt se ut och vad kan göras för att effektivisera utvecklingen? Ett gränssnitt kan alltid utvecklas och bli bättre. En gräns måste emellertid sättas för när gränssnittet är redo att komma ut på marknaden.

The explosion of new digital media puts pressure for developments within copyright law both in Sweden and internationally. These developments are taking place on two different international areas: (1) WIPO which is a part of the UN family and (2) the EU where a new directive on copyright law is being prepared and probably implemented during 2001. The aim of this thesis is twofold: (1) to study which considerations libraries must make when handling the new digital media both under today's copyright laws and under those which are being developed internationally. (2) What will be the consequences, for Swedish libraries, if the new EU-directive on copyright law is implemented in Sweden? By analysing current copyright laws, international treaties and the proposal for a new EU-directive as well as the national debate the thesis brings attention to a number of central issues for libraries.

The purpose of this thesis is to examine and analyze why, in the case of Afghanistan, the government chose to establish a highly centralized political system, when from a democratic standpoint a less centralized system would be preferable.The time period that is examined span from 2001 when the so-called Bonn-Accord was signed, to the parliamentary elections held in 2005, a period often referred to as the Bonn-process.The theoretical framework examines both the complex relations between federalism and democracy, as well as the relation between federalism and the role of existent ethnic minorities. The theoretical framework is then used in order to explain why it would be problematic to create a federal system in Afghanistan under the present circumstances.The conclusions that can be drawn are the following: In case of the republic Afghanistan the creation and implementation of a highly centralized political system was the only possible way for the government to be able to cope and practically deal with the problems of existent ethnic antagonism and regional warlords in order to create a stable political situation in the country..
