This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

Denna studie har resulterat i ett nytt koncept med tillhörande design för hur individualiserad informationspresentation till förare i bilar skulle kunna se ut. Designen har framkommit genom litteraturstudier, State of the Art studier om informationssystem i dagens nya bilar, domänexpertintervjuer och användarstudier i form av Goal Directed Design. Slutligen utvärderades designen. Litteraturstudierna gav en god grund för vilken informationspresentation som finns i bilar idag. State of the Art studierna resulterade i en sammanfattning av nya informationssystem som fanns i tre nya bilar från tre olika bilmärken.

Private state aid enforcement with respect to below market value transactions carried out by Swedish municipalities ? A study on the conformity of Swedish procedural and substantial rules with the principle of effectiveness of EC law Recently in Sweden, several local governmental entities (municipalities) have engaged in commercial transactions that, essentially, have been aimed at transferring the ownership of public services ? for example schools and local medical care centers ? to private undertakings. A few of these transactions have been declared by Swedish administrative courts to constitute illegal below market value transfers of public resources. The essay seeks to determine whether the Swedish national provisions that govern legal claims based on the directly effective Art. 88(3) of the EC Treaty, are compatible with the principle of effectiveness, i.e.

The purpose of this study is to analyze how the parties (USA, Great Britain, UN and the European Union) legitimize their intervention in Bosnia-Herzegovina as seen from without the conceptions of sovereignty and intervention. USA and the UN have legitimized their intervention on security reasons. The American president, George W. Bush, claimed that democracies never engage in war with each other and that democracies were prosperous just because they were democracies. According to the president, that is why it is important to democratise the whole Balkan region to protect the international community from terrorism which grows in unstable and undemocratic states.

The way in which media discusses religion has changed over time. Due to the separation of state and church in 2000, the Swedish state to a lesser extent legitimizes its political ruling with references to religious concepts. As a result, a higher tolerance towards religious minorities can be said to have taken place. This is an ambiguous change however, where critique raised towards religious practices and expressions of minorities also occurs to a higher extent. The public debate is in large part conducted through the media, but is also seen to be produced and reproduced through the media?s discourse.

This masters thesis aims to explore the branch libraries in Kalmar municipality and their relation to the Information and communication technology ICTsociety. How do they adapt to and assimilate with, the ICT-society? What are their roles in local social networks and do they make a difference there? To answer these questions, critical discourse analysis, CDA, as founded by Norman Fairclough is applied to four interwievs with branch library managers. Other theorists used are Michel Foucault, Chaïm Perelman and Ludwig Wittgenstein. A solid description of todays society on different levels is also given.

Fall accidents are a big problem in the construction industry today and stand forapproximately 23% of all accidents. Skanska is a construction company that has avision toachieve zero accidents. Eliminating fall accidents is one step on the way towards theirvision. The state of Skanskas fall safety has been analyzed in this thesis to show whichimprovements are possible in fall safety.A literature study has been performed in which Arbetsmiljöverkets (The Swedishwork environment authority?s) laws and rules, together with Skanskas own rules havebeen studied.

The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.

Syftet med studien var att undersöka självförtroende och kroppsbild hos datorspelare, styrketränare och en kontrollgrupp. En webbenkät med manliga medlemmar på dator- och idrottsrelaterade internetforum genomfördes. Kontrollgruppen var medlemmar på dessa forum som varken styrketränade eller spelade datorspel. Skalorna Social physique anxiety scale, Rosenberg self-esteem scale och Drive for muscularity scale administrerades. Resultatet visar att grupperna inte var signifikant skilda åt gällande social fysisk ångest eller självförtroende.

This study aims to investigate development and reasons behind sustainability reporting in large Swedish companies. By examining 15 companies? environmental and sustainability reports between the years 2000 and 2008, data was collected on matters such as frequency, scope and design. Identified trends were to a large extent in line with previous studies on international development; sustainability reporting is growing in several aspects. The authors have found one major reason for this development to be increasing requirements and expectations from stakeholders and a need for companies to legitimize their actions.

Det saknas en beskrivning i den svenska grammatiken över hur adjektiv förstärks med hjälp av förled. Forskning visar att fenomenet med förstärkningar, även kallade intensifierare, uppmärksammats mer i andra språk. Syftet med denna undersökning var att beskriva och kartlägga användandet av förledsförstärkningar, samt se om det fanns några hittills oskrivna regler och mönster. Här gjordes en kvantitativ undersöking där frågeställningarna analyserades utifrån statistiska data insamlade ur två korpusar bestående av bloggtext. Adjektiv inom sinnelag, stabila egenskaper, och sinnesstäming, temporära egenskaper, samt parametrarna positiva och negativa adjektiv undersöktes.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.
