The aim of this report is to examine the possibilities to use network theories to perform vulnerability analysis on complex networks. The scoop of this work is also to improve the possibilities to chart, analyze and present the vulnerability in a power grid. In this report it has been, using power outage statistics, possible to verify, that network theories can be used to evaluate the vulnerability of an infrastructure network. However further studies to establish values on how vulnerable a network is are needed..

This examination work is about implementation of Cisco Systems Network Admission Control (NAC) within a leading IT-company in region of Jönköping. NAC is a technique that is used for securing the internal network from the inside. NAC can verify that the client who connects to the network has the latest antivirus updates and latest operative system hotfixes. Clients who don?t meet the criteria can be placed in quarantine VLAN where they only have access to the update servers.

No infrastructures today are growing faster then communication network. The requirement of being able to communicate in a fast and qualified environment to a low cost increases in line with the development and competition. Itera Networks is no exception when it comes to rapidly developing new and better network solutions for themselves and for their customers. With these requirements in mind their needs for an analysis of the existing communication solution becomes very obvious. This project contains such an analysis in which various studies of the existing network environment have been made.

The purpose of this thesis is to examine value creation in networks. Based on a case study of Livebookings Network, an online booking service. This thesis has an explorative nature. As a theoretical framework we use theories on value and network dynamics. By combining these theories we develop an operationalized framework that we use to analyze our empirical findings.

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.

Author Cocitation Analysis (ACA), multidimensional scaling (MDS) and Social Network analysis (SNA), has been used to analyze and visualize the invisible college of the journal European Union Politics. The concept invisible college was first introduced in the fifteenth century, through the creation of the ?the Royal Society of London?, and it was reintroduced in the 1960:ies and the 1970:ies by scholars such as Price and Crane. It is said to have been interpreted in as many ways as there are authors who have used it. Here it has been used synonymously with the term citation network.

The purpose of this master`s thesis is to examine how the contemporary changes in society display itself in the network Ecumenical Forum of European Christian Women EFECW and to increase the understanding of networks. My main questions are: What does the networks structure look like? What does the networks relationships look like? How is identity created in the network and what types of identities is created? The objectives are reached by using two methods, qualitative inquiries and document analysis. The inquiries were carried out to nine members in the network of different countries. The theoretical framework of the thesis is Manuel Castells theories of the network society, and the study is also placed in context by a presentation of previous research on the field.

Outages in the electric grid can be costly for society. Because of this, reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.

This thesis discusses various approaches that venture capitalists have when evaluating investment prospects. The thesis is a case study of the business angel network Firm Factory Network. The empirical material is based on an extensive interview with Firm Factory CEO Daniel Kaplan. Our conclusion is that Firm Factory Network uses both informal and formal methods when they evaluate interesting prospects..

The purpose with our study is to create an understanding of how tourism stakeholders within a tourism network can affect a Destination Marketing/Management Organization?s (DMO?s) work with the destination branding process. To fulfill this purpose we have clarified different relationships that can influence the DMO?s place marketing. In order to limit our study we have chosen to focus on two Swedish destinations, Öland and Norrköping, and their DMO?s.

Social networks have increased significantly during the latest decades, but what does the cooperation include and how does the network processes look like? Networks are not specific for communities in the 2000?s or for that matter human organisations, but the ability to build networks and introduce more actors to the organisation have become easier with today?s communication technology. The study is about the Norrköping Municipality membership in the transnational network Sweden Emilia Romagna Network (SERN). It gives an insight into how networking and cooperation can be seen by politicians and officials, based on mission statements and the reason why a municipality choose to participate in transnational networks. The study aims to examine how Norrköping Municipality uses the SERN network and what the network have resulted in since the beginning of the municipality membership in 2005. It is a qualitative study which involves interviews with officials and politicians from the Municipality of Norrköping and textual material from SERN?s strategy documents and policies.

In this paper, a small business network with around 30 users is analyzed with respect to security, performance and usability. Based on this analysis, two suggestions on how to solve the problems listed are given. The first suggestion focus on keeping a low budget, while the other tries to deal with the problems more thoroughly. One advantage of the first suggestion is, in addition to not straining the company's budget more than nessecary, it does not involve too great changes in the way the network is used and administered. On the other hand, the smaller budget leads to certain compromises, and there is a risk that similar problems occur again if, for example, the company would grow.

The theses discuss information seeking with a focus on Google and social networks. Students attending the librarian program in Lund have been examined by means of two methods; diaries and information horizons, where they had to solve a specific assignment. The information horizon as a method contributes to getting a structural perspective on the information search process instead of viewing information search as a procedure. Information horizons use social Network analysis.The aim of the theses is to investigate the importance of the social network in information search, with a particular focus on Google as a search tool. Our hypothesis is that Google acts as a compensator to the social network when the students search for information and in the educational program.The research indicates that there is no direct correlation between usage of the social network and usage of Google.

The purpose of this thesis is to explore the co-creation process and how value is created based on a service orientation using a network perspective. The thesis is studied from a social-constructionist philosophy, using a qualitative approach of data collection and the theoretical framework includes network theories, theories of service-orientation and co-creation. We have conducted semi-structured interviews with a small firm and its network, which consists of a customer, a supplier and a partner. We found that Håkansson?s ARA framework combined with Ballantyne and Varey?s triangulation of value-creating activities help to acquire an understanding of the actors? bonds, the resources? ties and the activity links that exist in a network.

AbstractTitle: Network communication for equal opportunities (Nätverkskommunikation för jämställdhet)Number of pages: 47 (54 with enclosures)Author: Hillevi GoodTutor: Ylva EkströmCourse: Media and Communication Studies DPeriod: Spring Semester 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The aim of this essay is to study the possibilities to bring about change by the means of communication in two networks, focusing on the implementation of the Swedish Equal Opportunities Act.Material and method: The study draws on data collected in an electronic survey among representatives of two networks consisting of representatives from trade unions and employer?s associations. The material is analyzed using descriptive tools, cross tables and correlation matrices in which general characteristics as well as individual understandings of the network communication are presented and discussed.Main results: The general results indicate that the network communication serves important purposes, such as providing support and motivation for the members and changing attitudes towards equal opportunities. The analysis suggests that the network members have good communicative possibilities to serve as agents of change within their organisations. Moreover, there is an observed relation between, on the one hand, organizational context and, on the other hand, the network members? own communicational behaviour and their experienced possibility to influence their organizations.Keywords: network communication, diffusion of innovations, behaviour change, Equal Opportunities Act.
