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. .

The study shows the current need for security solutions concerning work with information in different areas.Investigations will show important solutions for printers? needs to meet the increasingly harder demands forfast and safe digital communications. Important factors to be analyzed in the investigations are: access todifferent types of information, workers authority of information, access to the data base register internallyand externally, production solutions for an effective fault detection and data base solutions fororders and distribution.Planned and unplanned stops result in a standard of value in interruptions. Internal data bases areprotected by so-called ?Fire Walls?, ?Watch Dogs? and Virtual Private Networks.

This master thesis was written in the purpose to study how the location and access to computers in the physical realm of the public library reflects the undergoing changes in the public libraries role in Swedish society. This study is done in a form of a case study of three small public libraries. All of them were in the process of transforming both their physical and virtual space. The thesis focuses on where in the library the computers are placed and how their location interacts with the libraries main tasks. It also focuses on the analysis of the relationship between these two elements and how that relationship reflects the alteration of the public libraries place in society.

Sammanfattning Utvecklingen och utbredningen av Leveraged buyouts förvärv har ökat i Sverige de senaste 5-15 åren, detta kan vara ett resultat av ett mer flöde på kapital och intresse av att investera. Dessutom har förmodligen den allt mer mogna private equity marknad tillsammans med det ökande behovet av effektivisering av bolagen bidragit till att allt fler förvärv sker med belånat kapital. Vi har i denna kvalitativa uppsats intervjuat tre private equity företag med syfte att försöka klargöra vilka investeringskriterier som ligger till grund för en leveraged buyout-transaktion, samt vilka branscher som lockar dessa private equity företagen. I slutsatsen har det framkommit att PE-företagen gör investeringar i mogna företag utan några preferenser på specifika branscher. Vidare har vi funnit att de två viktigaste faktorer som PE-företagen tar i beaktning vid investeringar är stabila kassaflöden och kompetent företagsledning i målbolagen..

Avsikten med detta arbete har varit att undersöka huruvida någon prestandaskillnad föreligger mellan nätverksnodernas vidarebefordring av prioriterad trafik i en nätverksmiljö med Quality of service-funktioner (QoS) implementerade och nätverksnodernas arbete i samma nätverksmiljö med separata, virtuella nätverk uppsatta med hjälp av Virtual routing and forwarding (VRF). Målet var att resultatet ska ha möjlighet att väga in när för- och nackdelar mellan olika sätt att separera nätverkstrafik jämförs ur prestandasynpunkt. Rapporten beskriver arbetet med samt resultatet av ett empiriskt experiment som kontrollerade VRF:ers påverkan på QoS-funktioner. Ett fysiskt nätverk sattes upp för att kontrollera hur QoS påverkades av logisk separering av experimentmiljöns nätverk på lager tre med hjälp av VRF. I detta nätverk utfördes även ett kontrollexperiment utan logisk separation för att skapa en baseline samt ett experiment där separering utfördes med hjälp av accesslistor.

Titel: Private equity-ägande och dess ekonomiska konsekvenser hos portföljbolagBakgrund: Det finns omstridda resultat inom den akademiska världen när det gäller vilka ekonomiska konsekvenser private equity-ägande leder till. Olika studier har kommit fram till att private equity-ägda portföljbolag både över- och underpresterar gentemot jämförbara företag. Skillnaderna i studiernas resultat tycks påverkas av vilken marknad som studien är utförd på. Detta då studier som är gjorda på marknader med spridd ägarkoncentration tenderar att visa på att private equity-ägande leder till positiva ekonomiska konsekvenser och tvärtom på marknader med koncentrerat ägande. Tidigare studier har också valt att fokusera på att studera private equity-ägda portföljbolag under högkonjunktur eller under både hög- och lågkonjunktur, det finns således till vår kännedom ingen tidigare studie som isolerar sin studie till att endast inkludera lågkonjunktur, vilket understryker relevansen av denna studie.Syfte: Syftet med denna uppsats är att genom en empirisk analys avgöra om och vilka ekonomiska konsekvenser PE-ägande får hos portföljbolag under en lågkonjunktur på den svenska marknaden som präglas av hög ägarkoncentration.Metod: Denna studie har en deduktiv ansats där fokus ligger på teorier som berör private equity-bolags applicering av strategiska och organisatoriska förändringar hos portföljbolag.

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.

Venture capital firms and private equity firms have been the subject of much controversy in the last decade. During this period economies throughout the world have seen a steady increase of these types of firms as owners of companies. In Sweden this has certainly been the case and many argue that this trend will continue to grow stronger in the future. This trend is by many regarded as dangerous and as a threat to the ownership model that has characterized the Swedish economy for decades. Family ownership has been widely regarded as the most beneficial and responsible ownership model in Sweden.

The purpose of this study is to see how adolescent students in high school formulate their thoughts of death and if a belief in transcendent existence affects their thoughts. The study was done on two separate schools, one municipal school and one private religious school, in minor cities in Sweden. The method used was qualitative inquiries and the amount of participants was four from each school, eight in total. The result of the study showed that six out of eight participants had a belief of a transcendent existence, three from the municipal school and three from the religious private school. The result also showed that the participants from the municipal school that had a belief in an transcendent existence also had a belief in a form of ?afterlife?, this was however not reflected on the students in the religious private school where result showed that one out of four had a belief in a form of ?afterlife? and three view death as the final stage of existence..

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.

Many grocery stores have products marked whit there private brands. The information about these brands is poor. We wanted to find out what the stores own brands stand for and what the manager of purchase thinks it stands for. We choose to concentrate on meat and cured meat and limit our study to ICA, Axfood and Coop because they are the three main actors in the Swedish branch of grocery. The supplier has traditionally manufactured products and made there own brands. These products have been distributed and sold to the consumer thru stores.

The aim of this thesis is to study how the form of ownership affects the freedom within an artistic organization such as a museum or an art gallery. I have compared a publicly owned organization, Moderna Museet, with a privately owned organization, Magasin 3. The study is limited to only investigating the area of exhibition activities. A qualitative method has been chosen, and the empirics have mainly been collected through semi-structured interviews.The result shows that the form of ownership affects the freedom. Overall, one can conclude that the missions of the organizations look different, where the privately owned organization is given a greater freedom within their mission than the publicly owned organization.

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..

This study focuses upon the new societal objects that are termed public privatepartnerships where the public sector forms strategic alliances with the private sectorand the civil society to manage the wicked issues of today. An exampel of suchcooperation is Vänerhamn AB where the municipalities around the lake of Vänernand the private shipping companies got togheter to handle an economic crisis of theshipping buisiness. The partnership Vänerhamn has developed from a problematicactivity to a healthy company and the aim of this thesis is to illuminate thisdevelopment through an historical institutional approach, focusing critical junctureto discover if the governance theory can be used to understand the partnershipspositive process. This will be done through research questions about the organisation of thepartnership, about the members interests with the partnership and about eventuallycoordination problems in the partnership. The questions derive from dimensions ingovernance theory, central for the activity of partnerships. Interviews with centralinformants where held and it was complemented through a document analyses inorder to search for indications of the dimensions and that is the methodologicalapproach of the study. The conclusion of this thesis is that the governance theory can be used tounderstand Vänerhamns postive development since the members interest with thepartnership to a begining was not at all conformed and that led to obviouscoordination problems.

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.
