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.

The purpose with this essay is to analyze Adlerz writing within the context of the fiery debate in the 1880?s between the liberal so called ?cultural radical? members of the student organization called Verdandi, and the conservative, uniform oskarian culture named after the Swedish king of the period. I have applied a version of Quentin Skinner?s method, which focuses on the context of a specific writing in order to find out the authors intention, the effect the author hoped to achieve. My questions regard certain themes I discovered in the text and, more importantly, the relationship between these themes and the surrounding debate.

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.

This work applies intersectionality to five Somali women self-narratives and focuses on their identities and positions in Swedish society, but also their relation to Somali society. Since people constructs in relation to the environment, this work studies the impact of environmental confirmations of their own self. Intersectionality is brought into the social work with an operational attempt, and shows how critics of power and interplay between theories and empirics can provide new knowledge. Intersectionality also demands some alterations of the social constructionists? idea of the ego.

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.

The aim of this study is to examine reading on the MobileReadforums. The term ?to read? is extended to also cover bookcollection and usage of new technology such as mobile readerunits.A catalyst for reading on mobile reader units seem to be the needto always have access to the personal e-book collection. Apartfrom being a source for reading the collection of e-books alsoserves the purpose of extending the members self-esteem.A large portion of the activities on the MobileRead forum isaimed at making new technology comprehensible with the help ofprotocols to determine the usage of that technology. The processof making protocols also seem to be another way for the membersto extend their self-esteem.Traditional libraries are mainly seen as one of many sources for ebooks.Librarians are mostly perceived as being service mindedbut lacking in e-book knowledge.There is also a risk for miscommunication as the library hasdeveloped other protocols that defines an e-book and how itshould be used.This study is a qualitative analysis based on forum posts collectedfrom the MobileRead forum..

The downsizing of the Swedish armed forces during the late 20th century and early 21 th century has caused several thousand people to choose a different career. This undergraduate thesis investigates the self-observed employability and work-place competence of a number of Swedish armed forces officers who has made the transition to a civil career. The thesis seeks to answer questions about how the transition is comprehended, how military merits and competences are valued in civil work places and which differences in ability to use their competences the respondents experience. The study is made using qualitative interviews, which are analysed using a miexed method inspired by phenomenological method. The findings include that the essence of the respondents emplooyability is a shared work indentity as miltary officers and a common experienced problem in translating their merits.

The goal of this project was to create a web-based, crowd-sourced, correlational database, that easily allowed users to submit objects and receive correlated objects as results. The webservice was created in the web development languages of HTML, CSS, PHP and Javscript, with MySQL to handle the database. Simultaneous development was kept in check with the aid of the source code management system GIT. Upon completion, the service contained several HTML-views, the ability to add and rate objects, a per-object dedicated page with information parsed from Wikipedia.org, and a view with objects ranked in accordance to the preferences specific to the current user. Roughly a month after the beginning of development, the website was publicly launched and promoted in order to collect data, and improvements were added to the website as needed.

The Afghan war post 9/11 has become the source of multiple case studies. Recent studies suggest that variations in domestic support for deployment of troops in Afghanistan can be explained by means of the strategic narratives provided by the policymakers of the contributing state; a strong consistent narrative increases public support. Scholars recognize a Swedish catch-all narrative, which suggests weakens the narrative, thus raising the uncertainty among the public. This thesis investigates the projection of Swedish strategic narrative through elite Swedish newspapers. The content analysis reveals an inconsistency between the policymaker?s formation of the strategic narrative and the narrative projected by individual newspapers.

Lameness from the carpus is not unusual in the horse. Multiple soft tissue structures such as tendons, ligaments, the joint capsule and synovial structures can be the originating source. All these structures can be examined with ultrasound, although a description of a systematic examination method is lacking. That is ? which structures, what they look like in an ultrasound examination, how to look at them in the best way, and in what order.

Bakgrund: Varje år drabbas 55 000 personer i Sverige av cancer och behandlas oftast med kombinerade behandlingar. Den vanligaste biverkningen och det mest påfrestande symtomet vid cancer är fatigue. Fatigue betyder extrem trötthet/utmattninig och är en subjektiv upplevelse. Fatigue är inte en trötthet som går över efter sömn och vila.Syfte: Syftet med denna litteraturstudie är att beskriva hur det är att leva med fatigue vid cancer och cancerbehandling.Metod: En systematisk litteraturstudie som bygger på 15 vetenskapliga artiklar. Artiklarna är både kvalitativa och kvantitativa och har kvalitetsgranskats utifrån Fribergs kriterier för analys av vetenskapliga studier.
