Network Interdiction-problem innehåller två mot varandra stående styrkor, en användare och en angripare, somär inbegripna i en krigsliknande konflikt. Användaren använder ett nätverk för att optimera en funktion, t.ex.att förflytta en underhållskonvoj så snabbt som möjligt, eller maximera mängden materiel som transporterasgenom nätverket. Det innebär att användaren vill använda den kortaste eller snabbaste vägen vid transporter,och han vill maximera flödet genom nätverket. Nätverket kan t.ex. vara ett vägnät, kraftförsörjningsnät eller ettdatornätverk.

This document?s content is the final report of the master´s dissertation Magnus Hällström did during springtime of year 2013. The dissertation?s subject is 802.11s wireless mesh networks with streaming video as a focus point.  During the dissertation a wireless mesh network was set up with different attached cameras for streaming video. A sun panel solution was also tested with the goal of creating a package with a self-configuring network node streaming video, powered by nothing but solar energy. .

This report is a specialization in Software defined networking. SDN really comes to revolutionize the industry and it?s under constant development. But is the technology ready to be launched into operation yet? The report would initially involve a number of problems that today's network technology is facing.

Today?s electrical grid companies understand that better knowledge of and information about their grid can help realize a smart grid network. One way to gain better knowledge and information about the low voltage network is to install measuring equipment on the substation transformer´s secondary low voltage side that measures the low voltage network losses for that specific substation. By doing so, grid companies can, due to the calculation of the low voltage network losses, identify and address issues such as illegal power dissipation, unmeasured power outtakes, and unsatisfied technical documentation for the substations low voltage network.During 2012, Mälarenergi Elnät AB had a total electrical network loss (both medium and low voltage network losses included) of three to four percent of their total distributed electrical volume. Converting this energy volume into a monetary figure this accounts for a loss of around 30 million Swedish crowns.

This essay has discussed and analyzed a draft for an idea about a network called EduSync. This idea is based on that teachers and students, attending and holding courses, all over the world should be able to find and interact with each other. EduSync is founded from a new learning theory, connectivism. Interviews, participation in a conference and two workshops have been used to gather information and different points of view concerning e-learning, for example possibilities and problems with this idea of a network.  A comparison of web communities and e-learning environments that exists today was also done. The gathered information from persons as well as literature resulted in a discussion concerning learning and what would or would not be possible with the creation of EduSync.

Homelessness has always been and will always be a problem in every society. How should we organize the work and care for these people? There are three different types of welfare states, the liberal, the conservative and the social democratic. In the liberal welfare state the market is the supplier of the public good. In the conservative state the family and church and in the social democratic the state is the supplier of the public welfare.The Swedish welfare state has been the archetype of social democratic welfare with de principal of ?Folkhemmet? in focus.

Background: The fierce competetivness that characterize todays market force the companies to differentiate their offerings to a greater extent. The customers do no longer choose their supplier on the attributes of the products alone. Their purchase decisions also depend on the relationship the customers have with their supplier. With new customer channels like the Internet and advanced computer systems companies can increase the value for their customers through a better understanding of the customers needs and preferences. In this way companies can create longterm relationships with their customers.

HMS Industrial Networks AB is in need of changing a communications solution that iscurrently based on an ASIC. This will be achieved by moving the communications solution toa FPGA with the help of the programming language VHDL. By doing this, it is possible toreduce the need for specific circuits, get a more flexible platform and thus get a cheapersolution.This report describes a solution for how to move a network protocol from an ASIC to anFPGA. The report shows that the network slave device is working under the guidelines forthis project. This means that it is quite realistic to implement a fieldbus protocol on an FPGA,using VHDL and to maintain the same functionality as the earlier communications solution..

The present thesis closer examines what has come to be known as al-Qaida, partly from what al-Qaida is considered to be, partly from the consequences a certain picture of al-Qaida might give rise to. Between 1988-2001 most of this thesis sources refers to al-Qaida as a small, organized core group with some degree of cell structure. From 1991 to present days, many of the sources enlarge the picture of al-Qaida. From now on they start to view al-Qaida as either a network in itself or al-Qaida as a part of a larger islamistic network, not only as an organized core group with presumptive bases in Afghanistan. The most recent of theories regarding al-Qaida looks at al-Qaida as an ideology in itself (al-Qaedaism) or al-Qaida as a part of previously existing ideologies (Islamism, Neofundamentalism and Jihadism-Salafism).Al-Qaida is being seen - by scholars, journalists and terrorism experts - as an organization with a core group, a network in itself, part of a larger islamistic network and an ideology of its own or as a part of already existing ideologies.

The complex, ever growing and changing environment, requires that today's organizations are dynamic and willing to change in order to stand competitive.This awareness has made change number one priority in almost all organizations' agenda.We live in a world that is constantly changing, yet many organizations fail to change successfully. When a change occurs in complex environments with multiple stakeholders, it immediately increases the complexity and the challenges of the change process.A complex situation may arise when, for example, partial outsourcing of the corporate information system infrastructure. Two of the most difficult challenges that organizations face today is to conduct a successful change process and managing the effect of a change, such as arising expectations. It is very common for change in an organization not to achieve the desired result or that they even fail. There may be a lot of reasons for these failures.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made. Just over one fifth of the blogs are linkted to each other in one big network, where the remaining blogs stand without any ingoing or outgoing links.

The purpose of the study isto,based on network theory, systems theory and development ecological systems theory,understand parent?sexperiences of having children with autismspectrum, as well as understand the importance of social networksfor the parents. All of the intervieweeswere mothers. The results showed that it is important to parentsto have contact with other parents who are in the same situation as them. Many of the interviewees had a small social network.

The departure point of this thesis is the context of the institution and the processes surrounding the handling of personal archives at the National Library of Sweden. These processes are examined using Actor Network Theory. Around the personal archive a network is constructed and contained by actors ? the archive itself, the librarian, the conservator, the researcher, organizational structures and others. Within this network choices are made of what is significant.

En sammanfattning av uppsatsen på maximalt 8000 tecken.This thesis is mainly dealing with the mobility of the employees within the borders of the European Union. Legislative framework from the EU is favourable and the Commission has set as one of it goals to promote the migration. Globalisation trends and contemporary business concepts need people who are mobile on the other hand. But migration numbers are still low within Europe. The purpose of this thesis is to find out how much the legal uncertainties, and the different culture mentality in the workplace of another country act as barriers in the minds of the people who wish to work abroad.
