Ordets blomma kommer inte att dö : att förändra världar genom globala nätverk
Social movements have long been valuable components of the struggle for a world with true justice. Along with the changing and modernization of society these movements also change, both in their actions as well as in the goals they want to accomplish. Technology is taking a greater part in many aspects of social life, creating new dimensions but also new social divides. This thesis examines how new social movements make themselves visible and affect the world around them through different kinds of networks. For the purpose of this study, we have chosen to study two social movements; the Zapatistas in Mexico, who have become known worldwide for carrying out the first informational revolution, and MoveOn.org, an American grassroots organization that struggles for increased democracy in the US.
Trådlös kommunikation för Anybus
The industry struggles with problems concerning physical damage to wiresand communication in remote areas. Introducing a wireless network canprovide a solution to these issues. However, introducing wirelesscommunication comes with a whole new line of problems that will becovered in this report. By utilizing the wireless communication standardIEEE 802.11 a product can easily be integrated into an existing wiredEthernet network (IEEE 802.3).An introduction to the standard IEEE 802.11 and a summary of existingproducts utilizing the standard for embedded systems will be giventhroughout the report. This report also tries to explain key parameters forwireless communication in an industrial environment.This project also consists of a design and an implementation part, where thechosen IEEE 802.11 standard will be integrated into the existing wiredAnybus-S Ethernet module from the company HMS Industrial Networks.The integration part of the project has resulted in a working prototype calledAnybus-S Ethernet Wireless that utilizes the IEEE 802.11b/g standard fortransferring data.The project has been really fun to participate in and it has been successful inthe terms that a working prototype exists, and the authors have gained theknowledge in the subject as intended..

Man ville undersöka vad man i svenska företag vill åstadkomma med sin internavräkning.
Allmänhetens säkerhetsmedvetenhet med avseende på trådlös kommunikation
Offentliga trådlösa nätverk finns idag mer tillgängliga än någonsin. Samtidigt haralla dessa nätverk något gemensamt ? de går alla att avlyssna och risken finns attanvändarens information kan komma i fel händer. Uppsatsen behandlarallmänhetens säkerhetsmedvetenhet med avseende på denna typ av nätverk genomtvå undersökningar. Den första undersökningen sker via ett tekniskt experiment därdet på flera geografiska platser har erbjudits ett trådlöst nätverk till allmänheten.
Mellanstatligt samarbete mot människohandel i Europa : ? en studie om mål, åtgärder och resultat
This paper provides a study about human trafficking with sexual motives performed in European states and the measures taken from national, international and Non-Governmental organizations with the purpose to oppose human trafficking. According to the UN human trafficking has increased and shows tendencies to continue escalating, regardless of the measures taken by various organisations. In this study, four countries with associations to human trafficking have been chosen and organisations related to these countries are studied. The purpose is to inquire into how these organisations work against human trafficking and which objectives and guidelines these organisations strive for together with their values. The aim is to find out which result the organizations efforts gets and if, according to my hypothesis, the efforts oppose themselves.
Tolv böcker i datorn ? bättre än en i handen?
This thesis studies how readers of the electronic book (the e-book) use and perceive the electronic medium as a carrier of fiction. In this study it is assumed that fiction is mostly read in printed format. Therefore it is interesting to ask why some readers choose to read on screen. As there are all too few studies conducted on how readers perceive and use the e-book as a medium, this study aims to enrich an undeveloped research area. The study is based upon a qualitative questionnaire.
Implementering av Constant Fraction Detection vid avståndsmätning
This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one part is delayed half the pulse width and inverted. This signal is added to the original pulse. The resulting curve has the shape of a laying S and the detection of the zero level is used to stop the time measurement.
Produktspårning med RFID : Konceptutveckling och utvärdering
The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.
Borta bra, men hemma bäst: En undersökning av egna och köpta medier
The rise of social media has put a focus on the division of owned, paid and earned media, where earned media has recently been hyped at the expense of owned and paid media. Due to a novel area we examine the differences and effects of using owned and paid media, specifically for packaging versus newspapers. Owned and paid media showed no significant differences regarding credibility, persuasion and perceived commerciality, which restored owned media?s status, especially since owned media is more cost efficient. The effects of allowing ads for external brands on the owned medium were also studied.

The purpose of this paper is to contribute to a better understanding of what role the social support within different relationships can have on the process of giving up drug abuse. Furthermore the aim is to examine how a self-help group can provide social support in the transitional period after leaving a drug abuse.
Hantverket bakom intervjun: Studenters framställning av kvalitativa intervjuer som undersökningsmetod
When producing an interview report the researcher is put to the test of describing the qualitative interview method in terms of assumed orderly steps and procedures taken during the interview process, while at the same time account for a very social dynamic process. In practice, even the most carefully prepared scenario for a qualitative interview study probably does not correspond to the expectations made. What happens between the plans and the actual interview itself? This issue is investigated by contrasting the actual engagement of the participants in an interview project to how these relationships are accounted for in Master thesis from the Swedish School of Library- and Information Science in Borås. Theory and methodology from Actor Network Theory (ANT) have been applied into the area of qualitative interviews.
Mötesanläggningarnas framgångsfaktorer : En fallstudie av Stockholmsmässan och Stockholm Waterfront Congress Centre
The aim of this essay is to examine how important marketing and networking is for the meeting industry in Stockholm.
