Distributed system development is a common occurrence in today?s technological and global world. Because the consequences of its geographically distributed nature it creates barriers between people that affects their communication and collaboration efforts in the distributed context. Despite a lot of technological breakthroughs over the last decades and the occurrence of video-conference applications and other tools for communication and collaboration, cultural and geographical issues have so far not yet been completely resolved. In this study I have made a literature study over distributed system development to form a set of central factors that affects the distributed development process.

The overall goal of this diploma work is to produce a design of a 5 GHz radio frontend using Agilent Advanced Design System (ADS) and then build a working prototype. Using this prototype to determine if RF circuits at 5 GHz can be successfully produced using distributed components on a laminate substrate. The design process for the radio front-end consists of two stages. In the first stage the distributed components are designed and simulated, and in the second stage all components are merged into a PCB. This PCB is then manufactured and assembled.

The work has been carried out through an competitors analysis, qualitative interviews, literature studies and a survey on the target group. The findings of the work are that the market of freely distributed  magazines, both nationally and locally, is extremely wide and has many similar competitors.

This thesis work aims to describe the prerequisites for a distributed treatment platform for real-time sharing of rounds performed by paediatric oncologists. The work started during the autumn 2004 and is directly aimed at improving the situation for the thirty or so specialist treating children with cancer. The work is not limited to the description of such a platform but also to select suitable software and hardware for the implementation of the platform and further more to coordinate the implementation. The production of several documents describing the platform is also part of this work. The work successfully led to the implementation of such a platform as described in the published article Barnradioterapi på distans Kristenssen et.

Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.

This paper will expose the serious phenonomen Distributed Denial of Service (DDoS). Businesses without a good security policy are easy targets for attackers. We will cover why its hard to protect yourself, present previous attacks and ways for individuals and businesses to secure themselves. We have based our paper on previous cases and done intervjues with companies who specialize in dealing with these kind of threats. Then come up with guidelines wich will be helpful for businesses when they want to strengthen there security against Distributed Denial of Service-attacks..

The pedagogista is a new professional role in Swedish preschools. Some people question the role, which originates from Italy, since it is believed to carry out a pedagogical leadership that belongs to the head of the preschool according to the curriculum and the Education Act. Consequently, there is cause for examining what pedagogical leadership means in an organization with a pedagogista. However, re- search has shown the success of distributed leadership within schools. Hence, it ?s interesting to find out whether the pedagogical leadership of the pedagogista could be understood as distributed leadership and what that would implicate.The purpose of this thesis is to explain and understand the pedagogical leadership of the pedagogista.

An ethnographic study loosely informed by the theoretical framework of distributed cognition was carried out in order to describe how mariners have adopted the Automatic Identification System (AIS) in their work practice, or"made the technology their own". AIS is a transponder-based identification and communication system that allows ships to automatically identify and track each other. In addition to facilitating the identification and tracking of ships, objectives behind the introduction of AIS are to"simplify informational exchange", and"provide additional information to assist situation awareness". Participant observation and interviews were made at four different ships, as well as at two shore stations. A focus group was also held at a maritime conference.

The Swedish field of digital X-ray imaging has since several years relied heavily on distributed information systems and digital storage containers. To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback?the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.

Today many companies are global and can exist all over the world. It is more common that projects are conducted in different locations, from various cities in a country to nations in different parts of the world. To manage projects both traditional practices such as the Waterfall method and new flexible methods known as agile methods are used. How is the process affected when a project is distributed, when the team is scattered in different places? This makes it difficult to create a good project, something we will discuss and try to find solutions for.

The purpose of this paper is to explore branch librarians? ideals for mediating fiction and their view on the literature that are distributed by the Swedish Arts council. The study is based on the following questions: How do branch librarians reflect about mediating fiction? How do they express their view and their work with literature that are distributed by the Swedish Arts council? And which ideals of mediating can be distinguished from these expressions? To answer these questions a qualitative examination based on interviews with four branch librarians where used. The empiric material where then analysed by Jofrid Karner Smidt?s theory about different ideals for mediating fiction.

The purpose of this degree project is to study if there is a intentional work with technology in the elementary school, preschool to fifth grade, in a municipality. The work will also study what conditions there are in the schools in order to work with technology. 95 questionnaires were distributed to the responsible teachers in all primary schools in the municipality, from preschool to fifth grade. The results of the survey show that more than half of the respondents do not consider themselves to work with technology in the school. The conditions, in order to work with the school subject technology in the municipality, are primarily external such as: material, facilities and the ability to divide students into smaller groups.

This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.

Uppsatsen behandlar det amerikanska konceptet Distributed Operations (DO) kopplat mot den svenska doktrinutvecklingen. Uppsatsen bygger på Mika Ihalainens uppsats om DO som en framtida upprorsbekämpningsmetod. Uppsatsen avser fortsätta på Mika Ihalainens uppsats, och då främst med hans egna förslag på vidare forskning. Syftet med uppsatsen är att besvara frågeställningen ?Är Distributed Operations en förmåga eller en metod utifrån hur konceptet nyttjades under Falklandskriget?? och att ge ett konceptexempel på hur den svenska Försvarsmakten kan hantera en lågtek-nologisk fiende samt bidraga till den svenska doktrinutvecklingen, framförallt genom en definition av begreppen förmåga och metod.

Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofpiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent pile positions (up and low) was studied and compared to distributed deadwood samplesaround each pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, pile volume and decay stage were assessed to define any effect.
