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 main objective of this study was to evaluate animal welfare situation in Ethiopia during slaughter and to investigate chain activities between animal markets and Kera abattoir in Addis Abeba. In total, 442 animals were observed within 52 groups of cattle; both ox and calves with different breeds. The study was divided into four different sets of data collection; behavioural observations, recording of slaughter process, observation during transport and interview. During the behavioural observations, an ethogram was used with 46 behaviours observed, categorised into 5 different groups. The data was calculated using Excel and SAS. The results indicated that a significant correlation (p-value.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

This essay investigates the statements of Växjö municipality?s motives for some of its many environmental projects. The aim of the essay is to be theory-testing as to see how a municipality/city which promotes itself as being ?green? motivates its efforts in the environmental area. Växjö city promotes itself as ?The greenest city in Europe?, an award appointed to the city by BBC and other international media.

This case study presents how the unit of munition-searching dogs of the Swedish armed forces handles their experiences from international service. The subject is particularly interesting as previous research into the area is nonexistent. The questions asked in the study are answered through the authors findings that training and preparation of this unit has developed thanks to the input of lessons learned from previous missions. This paper, based manly on experience reports, show that the unit successfully uses the method for handling lessons learned chosen within the Swedish armed forces..

This master of economics paper discuss that the globalization has lead to increasing internationalization among small Swedish IT- companies in the service sector. Sweden has a long history of foreign trade but in the beginning of the industrialization only large companies that produced goods answered for the foreign trade. Before, the Swedish companies begun their operations abroad in fairly nearby markets and only gradually penetrated far-flung countries. Now this is no longer possible. When small companies nowadays seek growth in other countries there is no time internationalize with the same approaches as before, especially when the company offers a service.

Sverige och världen har under de senaste åren fått uppleva en fantastisk högkonjunktur. Det har varit lätt att låna pengar och företagen har gjort fina vinster. I spåren av god tillgång på kapital är företagsförvärv alltid aktuella. En relevant fråga för varje köpare är dock hur ett förvärv skall redovisas. Hur företagsförvärv skall redovisas har avseende noterade bolag genomgått genomgripande förändringar de senaste åren.

Since the 1st of May 2004 Cyprus is part of the European Union. The Republic of Cyprus as a whole is part of the Union, but all of the advantages of the Union membership cannot be enjoyed in all parts of the country. Since December 1963 the Cypriot administration has been separated into two, a Greek Cypriot and a Turkish Cypriot, and since 1974 the country is also territorially divided. The Greek Cypriot political administration is considered to be the legitimate representative of the Republic of Cyprus, the Turkish Cypriot administration is only recognised by Turkey. Since the disruption of the country in 1963 the UN has been trying to get the Cypriot parties to agree upon a peace solution in order to reunite the country.

AbstractThis study examines the conclusions made by Roland Paris in his case study of fourteen major post-war reconstruction efforts following the end of the Cold War, and applies them to the current reconstruction process in post-war Iraq. Paris found a common denominator of the fourteen cases ? a belief that a rapid liberalization process, turning war-torn states into liberal market democracies, would foster sustainable peace. Paris calls this belief ?Wilsonianism? after Woodrow Wilson, who was one of the first advocates of it.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

Today, the catering personnel are an essential part of the safety organization on board Swedish passenger vessels in ferry services. Their responsibilities for the safety on board have increased in connection with the changes in regulations made on the shipping industry. These changes have been mostly related to human factors and structural leadership in the last 25 years.A well-functioning safety organization requires competence and commitment from every individual. Previous researches on Swedish passenger ferries concerning the safety organization have raised issues regarding the catering personnel?s perception of the safety on board.

Laws, regulations and generally accepted accounting principles hold options on how companies should recognize revenue. Generally accepted accounting principles are determined by standard-setting bodies as the Accounting Standards Board and the Financial Supervisory Authority, which is influenced by international standard-setting bodies as the IASB. Service revenue is generally recognized when performance is completed, but there are variations in when a performance is considered complete. The different accounting options available create difficulties in comparing companies over time and between companies, which in turn creates difficulties to achieve a true and fair view. By clarifying what methods and principles in accounting for service income the unlisted companies in Sweden are using and why these differences exist, we have been able to study how the comparability and the true and fair view is affected by these differences.
