Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

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). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

Neutral bolagsskatt? : Analys om SOU 2014:40 skapar neutralitet mellan lånat och eget kapital

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

Dialogen som möjlighet till en ny miljöfilosofi : En analys av Djupekologins själv-realiseringsprincip

This is my thesis on the D-level at the university in Karlstad at the department for environmental science. It is an analysis of the idea of self-realisation in the deepecology movement.The Norwegian philosopher Arne Naess is one of the profiles in the foreground of deepecology in the world. His teories is important for the development of how to look at ecophilosophical matters in the nordic countries.i will therefor investigate his theories and see how Naess constructs the relation man-nature in his ecosophy T. The principle of self-realisation and identification is there the most important foundation for the antropocentric perspective.In my analysis I use Martin Bubers philosophy of dialogue and his thoughts about relational concept of the self as tools for my investigation.Ecophilosophy is an academic subject that touches a variety of fields of studies but has the collaboration between the subject of culture and nature as its base. Bubers concept of the self that highlights the third.

En utvärdering av två pearl growing-metoder i ISI Web of Science

The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.

Skolkuratorers handlingsutrymme i en pedagogisk kontext : En kvalitativ studie

The aim of this study has been to highlight how school social workers experience their discretion, and furthermore how they feel about working in a context mainly dedicated to teachers. The study is executed with a qualitative research method where ten interviews with school social workers, in eight schools in the area of Stockholm have been conducted. The theoretical framework used to analyze the results was discretion, street-level bureaucracy and human service organizations.The main findings of this study imply that the most important ambition of the social work that was conducted in the schools was to help the students reach their knowledge goals. The assignment is, however, not clearly defined, which has lead to school social workers defining the mission and goals themselves. They all have wide discretion and great possibilities to decide how to execute their work, but how they use the freedom that was given seems to vary among them.

Internationell jordbruksmark till salu - Nationell suveränitet, fattigdomsbekämpning & visionen om en hållbar utveckling

During 2008 we experienced an expansion of large scale investments in foreign farmland. This increasing trend has become a political hot-spot, but there is not much research available within the field. Due to a lack of research it remains a vital task to outline the potential effects of this trend. Drawing on existing ideas from some of the main actors within the field, The Food and Agriculture Organization of the United Nations (FAO), The World Bank, International Food Policy Research Institute (IFPRI) and the latest G8 summit on agriculture, four main purposes are set out for this paper. First, to outline some of the underlying mechanisms behind the trend is considered crucial for the understanding of the nature of these investments.

Svenska Lantchips : Och deras internationaliseringsprocess

Svenska Lantchips is a Swedish SME sized snack manufacturer. Being a small, medium sized, family-owned business with branches throughout the world, they make an interesting company for a case study. The case study I have conducted focuses on the internationalisation process of this family owned company ? how they, despite their size, find ways to keep up an unique business structure, designed for internationalisation.The aim of this essay is to compare Svenska Lantchips? internationalisation process with traditional internationalisation theories and see if these are compatible with this company. The theories used are The Uppsala Model, The Network Model, and The Born Global Theory, with The Born Global Theory representing the younger generation of models.After undertaking an in-depth interview with Michael Hansen, business developer at Svenska Lantchips, I collated a substantial amount of material, which I have used as the basis of this essay.

Application Lifecycle Management: : En studie av två Application Lifecycle Management system och deras stöd för systemutveckling i projektform

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.
