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 ISO 9000-series is a set of quality standards created by the International Organization for Standardization. The series is intended to provide guidance to companies in the process of deploying an effective quality management system. The series includes the requirements standard ISO 9001. This standard contains requirements on how a quality management system should be designed and how companies generally must work with quality issues. When a quality management system is introduced, if wanted, a quality certification can be implemented.

Syftet med denna uppsats är att undersöka vilka effekter ett styrsystem som Value Based Six Sigma gett för ITT Flygt. VBSS har influerats av främst Six Sigma men även Value Based Management och Nimbas värdemodell. Dessa begrepp presenteras närmare i uppsatsens teoriavsnitt..

This study is based on interviews with five unit managers working in the functional disabilities business. The purpose of this paper is to examine how these unit managers see their roles and their leadership, and to give the reader an insight into what it might entail to be a manager in social work. Theories applied are the role theory and three leadership theories. The previous research this study made ??use of affects ?leadership in social work" and "manager's role and leadership style."Being a unit manager of the functional disabilities business means having a so-called middle management position, which entails expectations being directed upon them from various avenues.

Uppsatsens syfte är att undersöka hur företag använder sig av den interna information som affärssystemet genererar. Vi i studien vill också studera skillnader mellan en teoretisk idealbild och praktisk användning. En kvalitativ fallstudie av Perstorp AB genomförts för att undersöka ovanstående. Den primära insamlingsmetoden var en besöksintervju. I studien presenteras ett urval av de befintliga teoretiska referenserna kring information, affärssystem och styrning, samt hur dessa hänger ihop inom ramen för studien.

The aim of this master?s thesis is to examine how managers in some public libraries are using performance measurements and to what extent decision making is based on the results. The main questions posed are:??What performance measurements and indicators are used in the libraries examined???What is the attitude towards performance measurements among library managers???How and to what extent are performance measurements and indicators used in the process of decision making???What improvement would library managers wish regarding the development of performance measurements in public libraries?The theory is based on a model of evaluation of the public sector in addition to general steps of evaluation of quality and performance measurement results. The investigation is based on qualitative interviews with seven managers of public libraries in Sweden.

The goal with this essay is to investigate problems in processes of a government agency andthereby determine whether a Business Process Reengineering can create a more effectiveworkflow. The foundation of this essay lies in how customers perceive its business processesas reported from Internet forums. By adopting a qualitative approach, this is supplemented bythe statements and reports from the public business. The qualitative method that has been usedin this study is a content analysis of the threads from two major Internet forums that highlightthe problems associated with the examination of firearms licensing and the routine that exists.The method also gave us the opportunity to study the public business own view of theirprocesses. This was done by exploring their statements in media and their own reports aboutthis area.This essay is the result of a case-based study and during the course of the study we haveidentified five themes related to; time, management, communication, competence, andregulations.

Vi har fått ett flertal viktiga insikter och lärdomar om nödvändiga ingredienser i god management. Först och främst en förståelse för hur viktigt det är med ökad självinsikt. Därigenom ökar förståelsen för andra personers beteende. Även det omvända gäller; genom andras beteende kan självinsikten öka. Lärdomen har implikationer på alla nivåer av management då en organisation grundar sig på samspelet mellan människor.

Law firms are defined as knowledge-intensive companies. Due to the dependency regarding the resource of knowledge among the firms employees and to the fact that they often are categorised as a type of professional service firm. The purpose of this study is to investigate the different types of profitsharingsystems as a form of reward with focus on the theoretical differences and effects of the True Partnershipmodel and the Stockholmmodel. In addition to these models we will look into the Human Resource processes of; recruiting, integration, retaining and development of employees. The main purpose of the study is to examine the theoretical level on how the profitsharingsystems effect different Human Resource processes and through the knowledge of these connections using this as an analogy when to analyse other law-firms and knowledge?intensive company?s.

Background: The world of sports possesses a lot of knowledge when it comes to leadarship and coaching. Coaching as a term is relatively new to the business industry and something that is up and coming among alot of companies. Leadership and coaching are two terms that can be combined with each other both in sports and in the business industry.Objectives: This study aims to compare leadership in sports and in the business industry. The purpose is to see if they can learn from each other and how they define the term leadership.Method: Interviews were chosen as a method in this study. Six individual interviews were performed and there were three leaders from the business industry and three leaders from the world of sport participating in the study.
