The paper discusses the problems contemporary Swedish art criticism faces when judging performance art and interactive art. Problems include among others that performance art is collectively ignored in Swedish newspaper art criticism. This prevents art critics from fair contextualising of contemporary performance art. Down in the rabbit hole, performance by Tris Vonna-Michell and its reception exemplifies these problems. Performance and interactive art seems to be disturbing art critics.

The purpose with this essay is to examine how arts and politics integrate to raise urgent messages and call upon social changes. Performance art as an artistic manifestation against the surveillance society has been studied to clarify this integration and through an empirical examination of the anarchistic performance group The Surveillance Camera Players. This group formed in New York City 1996 as a manifestation against the increased use of surveillance cameras in public places in Manhattan. Through performance in front of these cameras, The Surveillance Camera Players are able to express their protest against the surveillance society which, occurring to them, violates citizens constitutionally right to privacy. The development and signification of the surveillance society are examined through theoretical perspective by foremost Michel Foucault, but also by contemporary scientist in that field.

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.

Försvarets materielverk (FMV) står inför en omfattande ominriktning av verksamheten med tillhörande omorganisation. Den nya verksamheten innefattar att leverera tjänsten försvarslogistik till Försvarsmakten (FM). Då det inte finns någon entydig definition för vad försvarslogistik är så har detta arbete inriktats att utarbeta ett förslag till en sådan definition. Dessutom har en procedur skapats som identifierar relevanta prestandamått för ett godtyckligt försvarslogistiskt system, s.k. Key Performance Indicators (KPI), som kan användas för att påvisa om försvarslogistiken är effektiv eller inte.

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..

This report describes a system for verification of fingerprints against a previous created template. It describes how and why a fingerprint image must be processed before it can be used to either identify or verify a person. The method is based on special features of a fingerprint, called minutiae points. The whole process from image to matching is described, every step in the process with image enhancement, binarization, thinning and how to find the minutiae points. Also what false minutiae points are, how they arise, why they deteriorate the result, and how to handle them, is discussed.

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

The development of applications for mobile devices has exploded in recent times. This has also led to the introduction of several new mobile operating systems. To streamline application development for multiple platforms, techniques have been developed to be able to reuse the same application regardless of the operating system. If the same application can be used on multiple platforms it will save both a lot of time and money. Today there are three types of techniques to develop an application; web, hybrid and native application, where the latter is specific to the operating system it has been developed to.

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.

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 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.
