Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

This thesis explores the opinion of different participants in the music business regarding music being made available at the public libraries. The aim of the thesis is to answer the following questions; which are the most important issues concerning the distribution of music? How do the informants perceive the public libraries mission and activity in regard to make recorded music available? Which are the benefits/disadvantages with music being made available at public libraries? Seven qualitative, semi-structured interviews were conducted with representatives from the following organisations; SKAP (The Swedish Society of Popular Music Composers), FST (Society of Swedish Composers), SAMI (Swedish Artists and Musicians Interest Organisation) SMF (The Swedish Society of Musicians), SOM (Swedish Independent Musicproducers), IFPI (International Federation of the Phonographic Industry) and EMI Music Sweden. A study of literature and articles generated nine themes, which constitutes the frame of reference for the thesis. The result shows that several of the informants have not reflected upon the public library as an important actor when it comes to the distribution of music.

The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.

Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.

In this thesis is studied the electrical load of Paradisskolan with respect to power quality and energy consumption. The school's owner Trollhättans Tomt AB is also interested to know if they can reduce their costs by changing to smaller meter fuses. A recurring ground fault that?s been recorded from powerpanel A1A has been investigated. The school's equipped with an electrical bonding system, harmonic filters for the third harmonic currents, TN-S system from feeding transformer and groundfault monitoring.

The client, Senselogic, had noticed an increased demand for an e-commerce system integrated into its product, SiteVision, something that did not previously exist. Senselogic wanted to integrate a third-party system to manage e-commerce. The problem was that there were very many e-commerce solutions to choose from. In order to select the best system it was necessary to evaluate the e-commerce systems and compare them to each other. To identify the elements that has to be included in an e-commerce system a study of literature was conducted.

The SK 60 Aircraft has been a workhorse for the Air Force?s training of future pilots since the late 1960s. The aging SK60 aircraft is going out of style, and the system has merely a few years of total running time left. A replacement for the SK 60 needs to be implemented in the coming years, and the Armes Forces Flying School has been commissioned to conduct flight tests on suitable replacement systems. This study will conduct a system analysis of two aircrafts mentioned in the Flying Schools report.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

This thesis is based on a case study for the real estate manager Mimer in Västerås. Mimer provides a great deal of this city?s rental apartments. Many of their buildings have ventilation systems with a type of heat-recovery called ?heatpipe?.

The purpose of this Masters thesis is to compare classification codes and feature headings of three different universal classification schemes SAB, UDC and DDC, when classifying archaeological literature. The aim is to determine whether a subject analysis of a title generates similar feature headings in the three systems, and to find positive and negative things about each system from an archaeological point of view. The comparison and the analysis of the 22 chosen archaeological monographs showed that the subject analysis of the titles didnt always generate similar feature headings. This could depend on several things, for example different interpretations of the subject analysis of a document, less knowledge about the system and/or the subject, or the fact that its not the same classifier that creates the codes. The study also showed that the different classification systems did treat the subject archaeology a bit differently, and that its difficult to say that one of them is better for classifying archaeological literature.
