Dokumentet är ett resultat av studier gjorda under kursen Kandidatarbete I Datavetenskap. Arbetet utforskade, genom fallstudie, två egenskaper av distribuerade informationssystem och relation mellan dessa: säkerhet och prestanda. Målet med fallstudien har varit att belysa nackdelen med användning av Secure Socker Layer (SSL) dvs. dess effekt på hastigheten och fördelen med SSL, dvs. SSL:s roll i informationssäkerhetsarbetet. Arbetet visar hur prestanda i ett tillämpad distribuerat informationssystem kan påverkas av en SSL tillämpning.

The purpose of this paper is to investigate, analyse and interpret the educational ideals of the ABF (Workers Educational Association) as they are understood by five members within ABF. The paper also examines how the educational ideals are represented in the national guidelines and statues of the ABF. The basic theoretical perspectives are intercultural theory and theories about Bildung and adult liberal education in a multi-cultural pedagogical environment presented by Bernt Gustavsson and Hans Lorentz respectively.The empirical study consists of five semi-structured interviews and a text study of the official documents of the ABF. The data is interpreted with hermeneutic and semiotic tools. Organisational theory focusing on organizational culture has also contributed to the study.The result of the study, when analysed in accordance to the methods, shows mainly four things.

The social network services (SNS) on the Internet are becoming more common, and are starting to have a higher range of users, which is affecting Internet marketing. We (the authors) have a feelingthat a growing online marketing within social networks could interrupt the order of social standards. That is why we in this paper have tried to figure out what position marketing has ? and might have ? within SNS, and what impact it will have on social relations.During qualitative interviews along with both representatives of public relation offices as well as with SNS users, we became aware of the occurring strategies of online marketing, and the usersunderstanding of it. In the information from the interviews, we found some interesting contradictions on which this paper underlies.

IT ses idag som ett strategiskt verktyg med krav på uppnådd lönsamhet i alla IT-relaterade investeringar och projekt. Lönsamhet och kostnadseffektivitet är tillsammans med nya lagar och förordningar för bolagsstyrning viktiga faktorer som fordrar bättre IT-styrning. Att bedöma och värdera affärsnytta och nyttoeffekter av IT innebär att se vad IT?s egentliga värde är för verksamheten och dess affärsprocesser. Genom att använda någon av de nyare metoderna för nyttobedömning som också har fokus på oväntade och dolda kostnader men framför allt inkluderar skattning av snabba/långsamma nyttor och direkta/indirekta nyttor, så uppnår man bättre kontroll över verksamheten och att man fokuserar på rätt saker och gör dem på rätt sätt.

Words like pirates and anti-pirates are becoming common features in the cultural political debate of today, and the file-sharing phenomenon has become a more and more delicate and disputed subject. The fact that people are organizing in networks to swap computerfiles with each other has, among other things, led film and music companies from all over the world to initiate a number of anti-piracy organizations, assigned to protect the right to culture and information. The industrial organization Antipiratbyrån (the Anti-pirate Bureau) and the network Piratbyrån (the Pirate Bureau) have on several occasions been used to represent the prevailing conflict in Sweden. The purpose of this study is to apply a sociological perspective to the collective act of file sharing. Additionally, the purpose is to argue that the activity can be understood as a social movement, although it is rarely referred to as such.

The purpose of this thesis is to analyze and identify a selected number of key factors in successfully implementing open innovation. More precisely, it looks at how value is maximized using open innovation practices. The scientific approach taken is based largely on the network perspective, which puts relations to other companies in focus. An extended view of the resource based view (RBV), different from the traditional one by taking also external resources into account, is in addition central to understanding the use of external resources to create internal value. The two main research questions strive to look at how the company locates relevant partners and what the relations that are established with these partners should look like to get the most of open innovation.

Genom att fusionera (sammanföra) data från olika sensorer kan ett resultat uppnås som ger mer än de enskilda sensorerna var för sig. Här utreds vilka sensorer och sensorfusionsmetoder som kan vara aktuella att använda för Scanias adaptiva farthållare (ACC). Den adaptiva farthållaren anpassar det egna fordonets hastighet inte bara till en förinställd hastighet utan även till framförvarande fordons hastighet. Scanias ACC-system använder idag en radar för måldetektering.Det finns ett antal algoritmer och arkitekturer som passar för sensorfusionssystem beroende på nivån hos sensordatan och användningsområdet. Minstakvadratmetoder kan användas då data ska matchas mot en fysisk modell, ofta med lågnivådata.

This study focus on how physical and virtual meeting places may promote collaboration between firms and academia for the development of innovations. A case study was conducted on a meeting place that aims to support collaboration for the development of innovations in eHealth between different actors in the Linnaeus region. Data was collected through 6 interviews, whereas 3 with scientists and 3 with entrepreneurs. The data was analyzed based on a theoretical framework based on different perspectives on collaboration and networks, meetings and interaction and, physical and virtual meeting places.The results show that the purpose for collaboration is to be included in a network with other actors in the same area, gain increased knowledge of the subject area and to acquire new external contacts. Furthermore, in order to support collaboration, physical meeting places have to organize effective and interesting meetings.

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).

This paper deals with the subject internal communication. We received this assignment from Region Värmland, an organization formed jointly by the 16 municipalities in the county of Värmland, to take responsibility for regional development, growth issues, culture and adult education in Värmland. The organization consists of a number of geographically dispersed units with specialized working areas. In this type of organization, there are high demands on internal communication as a tool to coordinate the organization?s different units and integrate their work, in order to reach the common goals.

The way we socialize today is radically different from how it was only twenty years ago. Since the arrival of the Internet more and more of what we know about the lives of our friends comes from text-based social networks, or blogs. This means that we all, more or less, have become authors of our own life stories and that the reality we live in have become fictionalized. In this paper I explore what effects this postmodern process of dissolving boundaries has had on the autobiographical genre, where the line between fiction and reality is traditionally stressed. By analysing Carina Rydberg?s (b.

AbstractTitle: Swedish social media services (A study about Swedish social media services birth andhow they benefit from the Swedish climate)Number of pages: 38Author: Robin SchwabeggerTutor: Else NygrenCourse: Media and Communication Science CPeriod: Fall 2009University: Division of Informatics and Media, Uppsala University.Purpose/Aim: To see if the Swedish advantage or interest in developing new social mediaservices and networks has anything to do with our society. With society I mean our culture,attitudes and history. Do people, especially young people, have a more positive attitudetowards the Internet and has the fact that we, as a country, were among the first to use theInternet anything to do with it.Material/Method: Data collected from books, newspapers and articles from several sites onthe internet. I?ll use the information I?ve gathered to try to find an answer to my givenproblems for the paper.

Numerous studies raise the topic of highly educated immigrants whose education and list of qualifications devalue in the context of the Swedish labour market. However, little is known of those with foreign background who enter into higher education in Sweden. Our study attempts to shed some light onto the value of higher education relative to that of a person?s ethnic background. The background material features nine in-depth interviews of foreign background academics, as well as data extracted from an extensive survey study previously carried out at Växjö University. Initially, the quantitative data showed that students with foreign background, including Swedish-born children of immigrants, had not managed to find qualified work upon completion of studies to the same extent as their Swedish background counterparts.

Problemområde: Idag är användandet av peer-to-peer (P2P) - applikationer såsom KaZaa, ICQ och Seti@home utbrett bland privatpersoner. Användningen inom företag är dock ännu i sin linda. Vi kommer därför i den här uppsatsen utreda om ett eventuellt införande av P2P- teknik i ett företagsnätverk ger några fördelar jämfört med en klassisk Client/Server-lösning. Hypotes: Arbetet bygger på hypotesen: ?En P2P-lösning ger fördelar för företaget jämfört med en Client/Server-lösning? Genomförande: För jämförelsen mellan P2P och Client/Server definierades och jämfördes fem områden: Säkerhet, Användbarhet, Tillgänglighet, Bandbredd samt Utrustningskrav. Slutsats: Inom områdena Användbarhet och Tillgänglighet ger en P2P-lösning klara fördelar, däremot inom områdena Säkerhet och Bandbredd visar Client/Server- lösningen istället klara fördelar. Området Utrustningskrav är oavgjort då det inte finns någon märkbar skillnad på lösningarna. Säkerhetsproblemen är P2P-teknologins akilleshäl och det problem som är mest troligt att stoppa stora investeringar i framtiden om det inte löses. Slutsatsen av vår jämförelse blir sålunda: För ett företag som redan har ett existerande Client/Server-nätverk är det inte någon idé att helt byta system, däremot kan det vara av intresse att introducera en applikation som möjliggör skapandet av så kallade Virtuella Nätverk. För ett helt nytt företag kan skapandet av ett P2P-nätverk vara ett väl så intressant alternativ till Client/Server.

Vi kommer att undersöka om andelen utländska ägare i svenska börsföretag påverkar företagens nyckeltal. Nyckeltalen vi valt att undersöka är vinst, utdelning, vinst dividerat med kurs, direktavkastning och andel utdelad vinst. Vi har definierat utländskt ägande som: Den procentuella andel ägare registrerade utanför Sverige. Tidsspannet vi undersöker är 2002-2005.Vi ska i uppsatsen testa en hypotes. Hypotesen är att andelen utländskt ägande och företagens nyckeltal är korrelerade.
