Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

Syftet med den här uppsatsen är att tillsammans med ett posthumanistiskt perspektiv undersöka fenomenet socialt samspel i förskolan med fokus på hur ickemänniskor deltar i detta samspel. Empirin för studien samlades in, under vad som liknas vid en mindre fältstudie, på en förskola i Stockholm. I uppsatsen analyserar jag videoupptagningar från de deltagande observationerna tillsammans med ett antal performativa begrepp utifrån posthumanistisk teori.I dessa analyser blir det tydligt hur ickemänniskorna går att förstå som performativa agenter, som på många olika sätt deltar i samspelandet och formar barnens agerande och de roller barnen får. Genom att jag lyfter fram ickemänniskorna, och även sådana man ofta inte tänker på som så betydelsefulla som t.ex. små golvytor, en trälåda och ett bord, går det att förstå barnens agerande och samspelande, inte som uttryck för hur barnen verkligen är, utan som artikuleringar och översättningar av olika ickemänniskors kommunikation.

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 explores the position of book blogs in the literary system through Robert Escarpit's socio-literary model of the book market. Simultaneously the thesis serves as a test for Escarpit's theory: by actively applying his theory and model to a very new and contemporary actor on the book market I hoped to reach or confirm new insights into the usefulness and validity of Escarpit's work for contemporary socio-literary studies.Three book blogs were selected for the analysis and interviews were carried out with the authors. The interview questions were formulated specifically for the purpose of extracting the kind of information necessary for an analysis using Escarpit?s theory. As a complement to the interviews, statistics on the type of books reviewed on the blogs were also compiled.

The objective of this thesis was firstly to examine the possibilities of creating a universal tool for evaluating IT-security. When all the material was gathered we saw that we had strayed away from our subject and that our focus was on IT-threats and IT-professionals apprehensions and possibilities on the subject. The purpose of this thesis was there after to find and identify threats and counter measures in publications and later discuss these with IT-professionals. We found and identified several threats that the professionals encountered in their work. These threats ranged from techniques used by hackers to threats that can arise when the users on the network are poorly educated.

This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.

Why is the e-revolution of the Swedish film distribution lingering? In attempting to answer that question, this qualitative study depicts the distribution market of Swedish film and its actors. Thirteen interviews with representatives of the industry have been conducted in search of an understanding of the current situation. Two important conclusions are made. One is that the strong interdependency between the actors of film distribution is inhibiting the acting space of those who seek change.

Denna studie belyser behovet av alternativa synsätt och alternativa lösningar på hur bilismen och transportsektorn medverkar till miljöproblemen i samhället. Studien undersöker bilens roll för bilisten genom att lyfta fram förbindelsen bil-människa och hur denna förbindelse påverkar valet mellan bilen och kollektiva färdsätt i tre bostadsområden i Stockholmsregion. För att nå förståelse för förbindelsen bil-människa utgår studien från ett aktör-nätverksperspektiv. Metoden utgår från dels kvalitativa intervjuer och litteraturstudier.Under studiens gång uppstod ny förståelse för förbindelsen bil-människa. Denna cyborg är djupt förankrad i informanternas livssfär på grund av de starka skripts som är inskrivna i bilen vilka styr informanternas transportbeteende och överskuggar alternativa transportmedel.

Regional European Offices with the purpose to represent regions and municipalities in the EU-system have had a substantial expansion over the last years. One example is the North Sweden European Office for the counties of Norrbotten and Västerbotten, consisting of seven different headmen who are representing both the private sector as well as the public system. This diverse leadership representation makes North Sweden a very good example on a so called Quango, organisations that stand under simultaneous influence from both public and private sectors. These Quangos opens up new possibilities to solve public problems, but they also bring together two different working models which is not always easy to handle for a Quango. According to earlier surveys some characteristic Quango problems within North Sweden exist, for example the ability to prioritize and thereby be as effective as possible.

The aim of this thesis is to study a job-searching process and elements that affects it. The elements I have focused on are gender, class and social network. The study is based on interviews and a survey study with students from the educational program of Social work (Socialomsorgsutbildningen), that graduated 3 years ago. Through the survey I have examined their social-background and their job-searching process. The interviews are the main focus in the study.

The essay depicts the opposite views of the director and an actor during the filming of a specific scene in a feature film. The actor feels that he is not being listened to. This leads to unforeseen consequences for the director, as the actor no longer wishes to take part in the marketing of the film prior to its opening night. Everything is seen from the director?s point of view, she is working in a film world dominated by men.Questions are being asked if the director?s instructions are clear enough or if the actor, fearing getting lost, is mixing up his own feelings with those of the character he is portraying? What happens to the collaboration and how does it affect the rest of the team and the completion of the production? The director is also the producer.

This is a comparative case study with four ideal types.

According to the curriculum for primary schools, pre-school and after-school Lgr11 says that students should experience different feelings and moods using different forms of expression including drama (Lgr11 2011:10). The purpose of this study was to examine how educational drama is used in three elementary schools and for what purpose in teaching. The aim was also to examine the four teachers' perceptions of what educational drama means to them.I have used a qualitative approach with interviews and contacted four teachers from three different schools to get different information for my study. Three of them were educated teachers and one of them was an actor. The information provided in the interviews was analyzed using educational drama theory and previous research. The interviews with the teachers and the actor showed the use of different methods of educational drama in education.

The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.
