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..

Zpecta got indications from their customers that there was a need for other attachments. The purpose is to determine the customer?s requirements and the interfaces that are considered for Capella.During the thesis, Capella was only on the market for testing and evaluation.The thesis was initiated to create a specification.

This thesis investigates how recipient countries' domestic type of democracy affects its inclusive ownership in international development cooperation. This is done by examining Swedish development cooperation with Rwanda and Tanzania during the period from 2010 to 2014, a time when ownership - a concept which emphasizes recipient countries' leadership over its own development - was a central part of the international development agenda. The two cases were selected through a most similar case design where the value of potential explanatory variables was similar, except for the recipient countries' types of democracy. Furthermore, the case study uses a comparative analysis to analyze strategies and reports done by SIDA and the Swedish Ministry of Foreign Affairs. Previous research focuses on the exclusion that national ownership can result in, in undemocratic national contexts. The main argument for this should be seen as the fact that ownership can not be representative if the power of the recipient's development agenda is limited to a decision-making elite.

This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.

Background: When firms grow through acquisitions it is commonly debated whether the two entities ought to be better off as standalone companies rather than as a merged company. This thesis aims at discussing this issue of M&As advantages and disadvantages in terms of source of synergies from the perspective of resource allocation. Purpose: The purpose of this thesis is to describe and analyze to what extent pre-M&A differences (against similarities) in resource allocation and corporate culture between the acquiring and target firm have an impact on the post-M&A performance. Theoretical framework: Efficient market hypothesis, resource based view, strategic fit. Methodology: A longitudinal study is conducted on the EU market during 1992 to 2002 based on balance sheet and income statement data.

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.

Introduction: This thesis is about how the accounting entry provisions are linked to corporate market value. By statistically examining accounting and share data for 56 companies listed on NASDAQ OMX Stockholm, the question of whether accounting information regarding provisions are value relevant for investors is studied. Listed companies shall follow the rules of IAS 37 ? Provisions, Contingent liabilities and Contingent assets, when preparing financial statements.Aim: The purpose of this thesis is to examine the relationship between reported information about provisions and investors assessment of listed companies that comply with IFRS-regulations, by statistically testing the value relevance of the accounting entry.Method: The study is based on a quantitative, deductive methodological approach. The value relevance of provisions is examined by statistically testing the collected empirical data based on the two models that is described in the reference frame.Results: The conclusion to be drawn from the study is that reported provisions have no statistically significant association with return on shares and thus is not value relevant.

Aim: Earlier studies have investigated what impact the relationship between the auditor and their clients have on the auditor?s objectivity. There are different opinions about whether a close relationship harms or promote the auditors work. Furthermore there are studies that show what strategies the auditor (and client) tends to use in the negotiation between the two of them. On this basis we have chosen to study if there are any correlation between the nature of the auditor client relationship, the auditor?s negotiation strategy against the client and the auditor?s objectivity.Method: Because of our purpose to study if there is any correlation between the relationship, the negotiation strategies and the auditor´s objectivity we have chosen to implement a quantitative survey.

Envirotainer builds containers that are specialized in transporting of temperaturesensitive products these containers are customized for airplanes. The containers arethen leased to other companies, most often to pharmaceutical companies.Envirotainer are based in Lagga, Knivsta. It is also here where the production of thecontainers is held. The container RAP T2 was designed in the early 80ies. The RAPT2 contains a fleet of about 1220 containers spread all over the world.

The purpose of this essay is to examine Egyptian university students´attitudes about the Egyptian education system´s ability to support a democratic process in Egypt. In order to carry out my study, scientific books and articles have been read and interviews have been made among Egyptian university students. The interviews contained questions about the Egyptian education system´s impact on the democratic process in Egypt and which impact the Egyptian education system has had on the Egyptian revolution.The conclusion drawn from my study is that Egyptian university students find the contemporary Egyptian education system based on authoritarian rules and with a lack of democratic values. The Egyptian university students believe that to establish democratic institutions in Egypt, the Egyptian citizens need a better understanding about democratic values. However, some of the students believe that the democracy that should be established in Egypt, must be based on Islamic values and to succeed with that, Islamic studies must play a greater part in the Egyptian education.When it comes to the Egyptian education system´s impact on the Egyptian revolution the Egyptian university students´opinions were somehow divided. .

To assure good quality the software needs to be tested to find errors and to verify that the programme meets the customer?s expectations. Traditional methods are usually used in software development and means that a number of predetermined steps are followed. By using agile methods the development can more easily be adapted to the changes on the market. With these methods the testing is carried out continuously throughout the project.

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

In this thesis, I discuss the impact Swedish national culture may have on Swedish diplomats. This is a qualitative study and I have used theories from studies of international negotiations to compare the oppositional results of those scientists with my interview material. With the help of my interview material from seven Swedish diplomats and five foreign diplomats I have compared their perceptions of Swedish culture, Swedish diplomats and their thoughts about the existence of an international diplomatic culture with well known sceientists of international negotiations. My main question is whether there is an international diplomatic subculture, without any national impact, or not. The mission is to base the thesis with earlier science and then compare and contrast with my interview material.

The purpose of this Masters-thesis is to examine the impact of identity politics on (a) Turkey's foreign policy towards Europe and the EU, and (b) Europe's/EU's political attitude towards Turkey, and what implications this may have on a possibly future Turkish membership in the EU. It is a more interpreting thesis than it is an explaining one. The examination shows that Turkey has considered Europe as a political model, while Europe has used the muslime Turkey as a threat to determine its own identity. The negotiations between EU and Turkey this autumn will have great impact on the identity of both sites. If the EU accepted Turkey as a member, the union could gain a chance to spread democracy to the islamic world and thereby earn global respect.
