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..

The aim of this thesis was twofold, on the one hand to compile a set of usability and accessibility guidelines in order to establish the characteristics of a user friendly website, and on the other to test these guidelines on eight library webcourses with user education to see how well they adhered to the guidelines. The methods used were literature survey and source studies. The guidelines found in the literature survey were divided into four different categories: document properties, structure and navigability, visual characteristics and accessibility. In order to establish the adequacy of the guidelines, I examined reference sources, mostly on the web. To a certain extent this examination has been based on HCI Human-Computer interaction theories.

Internet is the world?s largest source of information, and it is expanding every day. It is possible to find all kind of information as long as you know how and where to look for it, but still it is only the words itself that are searched for. We have with this essay tried to find an approach that makes it possible to give the word a meaning or a context.We have, as a starting point used the Socrates method, which is a method that breaks down texts into its smallest elements and forms activities. We have redone these activities to ontologies by forming general and specific descriptions of the activities.

Nuförtiden är det mycket vanligt att människor och företag använder en hemsida för att synas. Hemsidor kan vara uppbyggda på olika sätt och av olika datorspråk, men de måste i grund och botten köras på en webbserver för att kunna fungera som en webbplats.Det här examenarbete undersöker prestandan för proprietär webbserver och webbserver som är av typen öppen källkod. Webbservrarna prestandatestades på hur väl de klarar av att distribuera olika sorters material som är vanligt förekommande i dagens webbsidor. Resultaten ifrån prestandamätningarna visar att webbservern av typen öppen källkod presterar i regel bättre än de proprietära webbservarna. En litteraturstudie genomfördes även för att se hur funktionaliteten för webbservern av typen öppen källkod kunde utvidgas.

In the year of 2006 I moved to South Africa for a year, a land that has fascinated me because of its history. During the time of my stay I became very surprised how strongly apartheid permeates the community where the white South Africans today are building walls around themselves. Through media we get surrounded with pictures that media creates and to find information regarding what?s happening in the world this is, most often, the primary source. Therefore I believe it?s interesting to explore how two different local newspapers from the county of Kalmar, with two different ideologies, present pictures of the same event, namely the revolt of Soweto in 1976 and how these two newspapers relates to racial policies.

The research on Ingmar Bergman is comprehensive, however, there is one aspect of his artistry that has been regrettably neglected ? his use of music. Music always played a huge part in Bergman?s life, and it was also a great source of inspiration. The music was a structural component in the creating process and he often referred to his films as pieces of music and his actors as musical instruments.

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.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

This study has a focus on brand building and brand identity. The overall idea of the study is to examine the Swedish clothing company WeAretheSuperlativeConspiracys brand building tactics and activities. WeAretheSuperlativeConspiracys, or WeSC, is a company that produces and sells streetfashion in over 20 countries and has over 1600 distributors. The company has in the recent years grown to become one of the largest in its segment. The interesting factor in WeSC´s brand building activities is the use of Weactivists.

Det finns flera fördelar med att digitalisera företagets affärsdokument; bland dessa kan nämnas minskade utrymmeskostnader och lättare delning av information. En process som inte sällan utgör en del av det elektroniska dokumenthanteringssystemet är hanteringen av dokumentmallar ? området som detta examensarbete kommer att fokusera på. Att på ett enkelt och smidigt sätt kunna förena data från ett affärssystem med en passande dokumentmall (kanske i form av en serverkomponent) och, baserat på denna process, generera t.ex. en faktura eller plocklista är något som varje elektroniskt dokumenthanteringssystem värt namnet borde kunna.

Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..

Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.

A trend in modern landscape architecture is to design pedestrian streets so that vehicles and people move in the same area. By doing this, traffic tends to slow down. On the market though, there is a lack of furniture that corresponds to the requirements of these kinds of public places. Therefore, I have designed this furniture, called VOX, which is planned to be used on streets, schoolyards and squares. One objective has been to promote the product to the industry.To achieve this, I have been in contact with people from different professions, which have all influenced my designprocess.

Branding is becoming increasingly important to companies within the B2B-sector and they put a lot of effort and capital to develop and strengthen their brands. One way of working with brands is through ingredient branding. An ingredient brand is an alliance between two brands where the ingredient brand is applied on a host brand and works as an ingredient on the product. The purpose of ingredient branding is to create competiveness, differentiation and to create quality associations. Ingredient brands can be divided into emotional and functional categories.
