<p>Detta arbete handlar om nätverksfilsystemsprotokollen SMB/CIFS, SMB2 och NFSv3. Arbetet baseras på artikeln ”A New Network File System is Born: Comparison of SMB2, CIFS, and NFS” som skrivits av Steven M. French på IBM, Samba Team. I den artikeln saknas det prestandatester och därför känns det relevant att göra prestandatester för att få fram vilket protokoll som har högst hastighet med olika filstorlekar i Windowsmiljö. Dessa tester utfördes mellan två Dell PowerEdge 2900 servar där den första agerade som klient och den andra som filserver. Testerna utfördes en gång utan nätverksfördröjningar (även kallat latens/latency) och en gång med. Detta resulterade i att vi fick stora skillnader i hur snabba protokollen är med och utan nätverksfördröjningar.</p> / <p>This essay is about the networkfilesystem protocols SMB/CIFS, SMB2 and NFSv3. The work is based on the article ”A New Network File System is Born: Comparison of SMB2, CIFS, and NFS” which is written by Steven M. French at IBM, Samba Team. In the article there are no performance tests, we found it relevant to do performance tests to see which networkfilesystem protocol was the fastest with different filesizes in a Windows client environment. These tests were performed between two Dell PowerEdge 2900 servers where one of them was acting client and the other one fileserver. The tests were done once without network latency and once with. This resulted in that we got differences in how fast the protocols were with and without network latency.</p>

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. To mark off my problem and information gathering I’ve decided touse three research questions which my work will circle around.Main Result: You can clearly tell that Sweden has a great climate for social media services tobe created. Sweden, as a country, had access to computers and internet in a very early stageand took great advantage of that. Their culture encourages creativity which is important andpeople in Sweden aren’t afraid to run into problems. Teenagers start uses internet in a veryearly age and they have a higher percent of daily usage then other countries.Keyword: File-sharing, Social media, Sweden, Skype, Spotify, Voddler, The Pirate Bay,Communication, Internet, Culture, Users, Consumers, Developers, Hofstede, Hartley

Bakgrund: Musikindustrin har upplevt omvälvande förändringar det senaste decenniet, där skivbolagen har tappat 50 % av sin försäljning sedan år 2000. Minskningen beror till stor del på det teknologiska paradigmskifte som skett i och med digitaliseringens intåg i musikindustrin, ett intåg som förändrat marknadsvillkoren för berörda parter. Syfte: Syftet är att förstå hur marknadsledande företag påverkas och handlar under teknologiska paradigmskiften, med utgångspunkt från skivbolagsindustrin. Vidare ämnar vi undersöka vad skivbolagen har haft för roll inom musikindustrin och hur den ser ut i dag efter digitaliseringens intåg. Metod: Uppsatsen är baserad på fyra intervjuer samt en e-postkorrenspondens med personer som har upplevt industrins utveckling de senaste åren. Som komplement till intervjuerna används sekundärdata. Resultat: Skivbolagen upplevde svårigheter i och med det teknologiska paradigmskifte som digitaliseringen stod för. Skivbolagen har efter ett defensivt beteende där de motverkat förändringen börjat arbeta för att skapa affärsmodeller som är applicerbara på den digitala marknaden. Studien visar även att skivbolagen har en viktig roll i musikindustrin, då de fungerar som en samordnare för de många funktioner som är involverade i en musikproduktion. / Background: Music industry has experienced substantial change in the last decade, in which record companies have lost 50% of its sales since the year 2000. The decrease is largely due to the technological paradigm shift that has taken place with the digitalization of the music industry. These changes have changed market conditions for existing companies. Aim: The aim of this study is to understand how market leading companies affects from and act during changes in technological paradigms with a focus on the record industry. Furthermore we will investigate the record companies’ role in the market and what their role is today after the digitalization of the market. Method: This essay is based on four interviews and one e-mail correspondence with people who have experienced the development of industry in the last decade. As complement secondary data has been used. Results: Record companies suffered difficulties due to the technological change of paradigm which was the result of digitalization. After defensive behavior the companies started to create new business models applicable on the digital market. This study also shows that record companies do have an important role in music industry as whole, as they work as a coordinator to the many functions involved in a music production.

Delta-Sigma Modulator-based Analog-to-Digital converter design is an active area of research. New topologies require extensive simulations to verify their performance. A series of improvements were made to an existing circuit simulation package in order to speed the simulation process for the designer. Various examples of these improvements are presented in typical applications. / Graduation date: 1992

Cette thèse se focalise sur le développement des algorithmes d'ordonnancement sous contrainte (m, k)-firm, ainsi que leurs applications pour la gestion de la qualité de service (QdS) dans les réseaux et systèmes temps réel distribués. L'objectif recherché est la ga-rantie déterministe de la QdS tout en maintenant un fort taux d'utilisation des ressources.<br />Les contributions sont (1) l'établissement d'une condition suffisante d'ordonnançabilité d'un ensemble de tâches sous l'algorithme « distance based priority »; (2) la définition de R-(m, k)-firm, un nouveau modèle qui relâche la contrainte (m, k)-firm et qui permet de modéliser de façon plus juste des exigences du temps réel souple; (3) le développement d'un algorithme efficace de dimensionnement de ressources sous contrainte (m, k)-firm relâchée; (4) la proposition de « Double Leaks Bucket » pour la gestion active de files d'attente permettant de maintenir une QdS en cas de surcharge des réseaux.

<p>Abstrakt: Den illegala fildelningen har blivit ett omdiskuterat ämne runt om i världen sedan fildelningstjänsten Napster skapades av unge Shawn Fanning. På senare år har flera nya fildelningstekniker utvecklas och upphovsrättskyddat material delas ut och laddas ner av hundratusentals tals personer runt om i Sverige. Syftet med rapporten är att ge en beskrivning av tekniker och lagar som tillämpas inom illegal fildelning. Samt att beskriva olika aktörer som figurerar inom den illegala fildelningen och vilka åtgärder de tillämpar för att fortsätta och skydda sin verksamhet.</p> / <p>Abstract: Illegal file sharing has become a hot topic around the world. The topic has been heavily discussed since the young Shawn Fanning created the file-sharing service Napster. In recent years many new file sharing technologies has been developed and copyrighted files is now shared and downloaded by hundreds of thousands of peoples in Sweden.</p><p>The thesis purpose is to give a description of technology and laws which are applied in the area of illegal file sharing. And also to describe different actors which appear within the area of illegal file sharing and which measures they apply to continue and protect their activities.</p>
