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.

The purpose of this thesis is to examine and analyse which effects a service strategy has on the control system of an organisation. The thesis takes a service perspective, and it is assumed that a service strategy gains competitive advantage and that the goal of the service strategy is to increase the customers? satisfaction level. A qualitative in-depth case study was performed on a Swedish beauty company. The organisation?s vertical structure was examined, from central to local level.

Finnhamn is a small group of islands in the Stockholm archipelago. At Stora Jolpan, the biggest island, there is a hostel. The main building was built in 1915 and is called Utsikten. The purpose of this project is to on behalf of the Archipelago Foundation (Skärgårdsstiftelsen) find alternative systems that can replace the existing heating system of Utsikten (an oil-fired boiler and electricity heaters) to a system with renewable energy. The alternative system that this project focuses on is a system of solar collectors combined with a wood chip boiler.

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 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 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.

One way of signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse?s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse?s performance and welfare (Manfredi et al., 2010). At the trot there are large vertical deviations of the horse?s body which the rider must adjust and adapt to (Terada et al., 2006) and an unsteady hand due to inability to follow the horse?s movement can be a source of discomfort and conflict behaviour in the horse (Heleski et al., 2009).

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.

In game development, performance is everything and the Playstation 3 provides a unique platform for utilizing parallelization of code to achieve extremely high performance.

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..

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.
