This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Hypertension is one of the most common reasons for visiting primary care. It is one of the most important modifiable risk factors for cardiovascular disease, suffering and death. Lifestyle change, such as increased physical activity is the foundation of treatment of hypertension. Lifestyle change starts as a process in which patients can be helped by a nurse through conscious communication, educate and support increased physical exercise.AimThe aim of this study was to investigate the district nurse´s experiences of interacting with patients with hypertension about physical activity.MethodIndividual qualitative study. Ten nurses from health center were interviewed.

This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.

Results: The informants described in the interviews, their perceptions of living with Type 2-diabetes. The analysis revealed the main category periodic health behavior built up on and related to five categories developed in data: preventive health awareness, guilt, confidence in medical treatment, motivational problems and periods of insight.Conclusion: This study contributes to understanding of patients with Type 2 - diabetes their beliefs about illness and how it affects everyday lives.Keywords: Believes, District nurses, Groundey Theory, Illness perception, Type 2-diabetes.

Vattenfall AB is a large producer of electric energy where approximately half of the energy comes from hydropower. Vattenfall Hydropower has got almost a 100-year old history and the company has developed a lot since 1909. After that the number of power plants increased and the competition got more intense, there were higher demands on the reliability. One way to secure the reliability with a good satisfaction at the power plants is to implement a maintenance method named Reliability-Centred Maintenance. RCM is a result of the introduction of the complex aeroplane Boeing 747 in the 1960?s.

A study has been conducted on how organizations in Sweden administer costs of facilities management services internally. There are three main theoretical methods for administering costs. In the first method, costs are maintained on a central level; in the second method, costs are allocated and in the third method, internal transfer pricing is used. The aim of the study is to identify which methods are applied in practice, to evaluate whether the methods fulfill their intended purposes and to study the relationship between the methods used and the cost level of facilites management services. In practice, a large diversity of methods are used for facilities management costs.

There is no commonly accepted definition of a business method. It ought to consist of a method or a process of doing business. Business methods constitutes a broad category of patents, it is hard to tell exactly what can be interpreted in to the term. Most of the world's legal systems have made an exception from patentability for business methods. In the USA the exception was abolished in a case 1998.

In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
