This thesis examines underpricing and the long run performance of IPO firms on the Swedish equity market during 1994-2010. We further investigate whether any correlation exist between underpricing and post-IPO performance during 36 months. We use a sample of 80 IPO firms. To examine the aftermarket performance we compare total return of each firm with a matching industry index. In order to strengthen our analysis, we run a second test, comparing actual return for each firm with expected return, adjusted for firm specific risk.

This paper aims to examine performance monitoring in project organisations. The number of organisations that regularly performs projects as a key part of their operations grows rapidly, why this topic has become of large interest. Through a theoretical framework developed by Lars Östman in 1977, the performance monitoring system of the Swedish government-owned public utility Svenska Kraftnät is studied closely. The results from this analysis are then linked to an analysis of the organisation's internal structure through Mintzbergs generic organisational structures. Close connections are found between organisational structure and performance monitoring, which leads on to interesting observations about the connection between size of a project organisation and choice of monitoring method..

The purpose of this thesis is to identify the factors that drive efficiency and effectiveness in technical development projects performed at A?F?s department of product development. In addition to identifying and analyzing these factors, the thesis also analyzes what needs to be taken in to account in order to implement a measurement system that is able to both monitor and control the identified factors.The thesis has been performed in a qualitative manner. It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.

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..

Application Lifecycle Management (ALM) is a genre of computerized systems which allows system development corporations to efficiently and more easily manage, maintain and handle the applications lifecycle. These ALM systems have a wide variety of tools which can be integrated to enable and support collaborative work, while they act at the core of the organisation. Todays ALM systems support flexible system development methods throughout the entire development process. This paper focuses on a case-study of a Swedish business- and technology corporation and their use of two ALM systems with an aim to unravel the differences between these systems and their functionality to serve as a basis for decision making regarding their utilization of best practice with their ALM-Systems. Meanwhile we studied their approach to ALM systems to see if they were using them according to the initial idea of ALM systems.

This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.

Too much attention has been given to mainstream approaches in performance management and management accounting research, without taking in to account changes in the environment with the rapid growth of online retailing. This paper evaluates how and/or if performance management differs in online contexts by using a conceptual model developed by Ferreira et al (2009). The model and its components are tested on three multichannel- and six e-commerce businesses. The result and its analysis is commented on by two e - commerce experts. The result shows that the operation method of the models twelve components do not differ in terms of work methods in online and offline contexts.

 Performance appraisals- a study of the performance appraisals significance as a tool for development in the public sector.Anders Larsson and Åsalill OlssonPerformance appraisals have been given a central role in leading businesses in the public sector and are seen as a tool to create development opportunities and achieve better results. This has resulted that performance appraisal in many organizations takes up capacity and time. This was the starting point of our interest to study whether the time spent on performance appraisals effectively pays for itself in the organization, in other words whether the effects expected actually are achieved. The paper examines first line managers` views on staff appraisal purposes and effects of a function within the Landstinget. The survey design, methodology and transaction are of qualitative and quantitative method with three different sources: literature review of previous research, interviews with first line managers in Landstinget Västmanland and the results from an employee satisfaction survey conducted on behalf of Landstinget Västmanland.

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

In almost every workplace today IT-systems have strong and significant roll in theeveryday work. It is therefore important that the systems have a good functionalityand that they work as an aid for the users. This thesis aims to study the systems atthe company Telge Nät and to analyse them from a usability perspective. By using thisperspective it has been obvious how difficult it is to make improvements on usability,once the system is in place. Even other larger improvements of the systems aredifficult to make at this stage and this is something that the users are aware of.

In game development, performance is everything and the Playstation 3 provides a unique platform for utilizing parallelization of code to achieve extremely high performance. In this master?s thesis the issue of animation with smooth skinning is migrated from being a GPU process to becoming a parallelized and 358% faster process. This method is incorporated in an existing commercial game engine and integrated in a currently in development title for the Playstation 3. An in-depth study covers parallel processors, the CELL processor, used in the Playstation 3, and how contemporary industry leading game developers are utilizing the same unique architecture to increase their own games? performance..

An attempt were made to record the 1st movement of Beethoven?s Op. 57, with the objective of performing it as close to Beethoven?s will as possible, in the tradition of the ?historically informed performance? movement.The result of evaluating source material rendered a list of the most relevant material for this study, and hopefully that might prove useful for other studies with similar objective concering HIP and composer-intention based ?autenticity?.However, Beethoven?s will was only vaguely captured in the limited source material accounted for in this study, rendering it moderate-to-small reliability. It?s probably possible to achieve a higher degree of goal achievement, given more time and through the utilization of music psychology to further extrapolate the detailed parameters of Beethoven?s presumed extramusical will.The recording made was not to my satisfaction and has strengthened my view that the interpreter should take council from the collected knowledge of scholarly sources but must ultimately remain free in whether and how to utilize that knowledge.Lastly, I?ve measured the bpm in the resulting recording with a error margin of ±0,02 s.
