The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the Network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to Networks the size of the Internet.

This piece of work develops a solution that automates protection against software keystroke loggers. Keystroke loggers can be used illegally to register a user's keystrokes and in that way acquire sensitive information. The solution was tested on two different Networks and the efficiency was measured. The Network represents an enterprise Network that uses the operating system Windows along with the directory service Active Directory. A script was developed to solve the automation matter.

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.

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.

This study intends to illuminate women?s experiences of their own self-harm. Self-harm is mostly associated with women and research shows that women mostly are over-represented. This study describes women?s experiences about their self-harm but also how they perceive the elements around them during their illness.

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.

Destination branding is becoming increasingly acknowledged by regions working with tourism. Underlying is the fragmented web of actors in the supply chain of which the tourism product consists of. The main purpose of our thesis was, from a management perspective, to gain an understanding and describing how a Network and the actors within it can build a consistent brand. We therefore chose to make a case study research on The Kingdom of Chrystal, or Glasriket, which is one of the most famous tourist destinations in Sweden. Our research is based on theoretical and empirical data.

The aim of this study has been to examine the role of control mechanisms when it comes to building relationships in a small business Network. In order to reach this goal, we have performed a case study of a Swedish supplier of machines to the engineering industry, which acts as the exclusive representative of a foreign manufacturer on the Swedish market. Main results: A number of control mechanisms, both formal and informal, could be identified in the Network. Their specific use, as well as relative importance differ between different actors in the Network. In general, the importance of formal control mechanisms decreases as the relationship evolves over time and the importance of informal ones, mainly trust, increases in a corresponding manner..

This thesis follows a qualitative method and aim to describe firms? international business at an emerging market seen from a Network perspective. The purpose of the thesis is to study in what way business relations and Networks influence the process of internationalization and describe the way in which companies handle the external Network in relation to acquisitions. Further does our purpose include analyzing if a firm?s Network may be the main factor for why international business occurs.

The main ambition of this degree project is to illustrate the fundamental problems of today?s electric tariff regulation and the usage of the analyzing tool; The Network Tariff Model. There is a further discussion of potential problems and clear improvements of the 2012 years proposed Network tariff regulation. Interviews have been conducted with specific Network companies and Energimarknadsinspektionen. The proposed regulation of 2012 is discussed from the government?s proposition.This paper clearly shows that the authority´s work has been conducted in a very unprofessional manner during the period of The Network Tariff Model.

Den här rapporten beskriver en experimentell studie av Microsoft Network Protection (NAP) och är ämnad för att utvärdera hur mogen tekniken är för att implementeras i en aktiv nätverksmiljö. För att göra studien tog vi hjälp av gymnasieskolan John Bauer i Kalmar. Tester har utförts med DHCP-framtvingning och 802. 1x-framtvingning, dessa är två av NAPs fyra olika framtvingande funktioner. En mindre analys av skolans switchkonfigurationer och interna säkerhet har även gjorts på John Bauers begäran.

Den klassiska approachen till navigering innefattar att agenten håller en intern representativ modell av omgivningen. Denna approach har emellertid många nackdelar, speciellt för dynamiska miljöer. En modernare approach är att förlita sig på den faktiska omgivningen istället för en modell av denna. Detta arbete presenterar en undersökning av navigeringsproblemet och hur väl det löses av agenter vars kontrollmekanismer utgörs artificiella neurala nätverk. Tillförlitligheten hos de två neurala arkitekturerna Extended sequential cascaded Network och Self-organized recurrent Network bestäms genom experiment.

AbstractTitel: Ur elden in i askan.
