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).

A debate in finance is whether a random investment gives the same return as carefully choose and valuing an amount of shares to invest in. Stock valuating Stock valuation is often done by fundamental valuation models, based on the company's underlying character, which tries to put a correct price on the stock. Today there are several different valuation models that can be used for this purpose. Since valuation models are only mathematical, equity research is underpinned by more subjective assessments about the company and its future.The purpose with this thesis is to describe which valuation models that are used by professional stock analysts, but also to see if the reliability on the equity research is affected by the used model to valuing the company. Furthermore, we want to see if the job that?s been done to understand the company, measured by the equity research quality, impact the reliability on the equity research.In this thesis, we have, to achieve our purpose, conducted a quantitative content analysis of 164 equity research done by professional analysts at firms listed on the Stockholm Stock Exchange. With basis in previous research, we have developed a method for determining the valuation model that is used in the equity research, the reliability on the equity research and a framework for assessing the quality of the equity research.In the theoretical framework the valuation models involved in our study are described, previous research on the reliability on the equity research and their practical use.

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

The paper directs to introduce the turkish literary tradition to an fairly unknown european audience, as well as to present a turkish poet called Orhan Veli. Since there is hardly any literature written within this subject in either swedish or english I have come to the conclusion that the europeans have not yet been subjected to a discussion of this nature. For this reason my main task has been to gather and compose all that has already been written within this matter. I have chosen not to dig deep into such an unexploared subject, but rather offer different types of entries with which further research can be pursued and built upon.The early literature in Turkey consisted mostly of imitations of the well established arabic- and persian traditions. Because of that the turkisk modernism came, in comparison to the rest of Europe, relatively late.

The purpose of this essay is to examine the Swedish governments discourse on integration of immigrants and thereby examine what social reality it constructs. The aim is to examine how integration and immigrants are constructed within the discourse. The method and theory being used in this essay is discourse theory. As a methodological instrument we use the policy on functional impairment as a comparison. The material being analyzed in this essay is political documents on the strategy on integration policy and the strategy on the policy of functional impairment.

Background: When companies decentralize their operations into profit centers, transfer pricing often becomes an integral part in intracompany trade. A profit center may affect both revenues and costs and seek to maximize profit. Transfer Pricing is a complex subject because it is affected by a large number of factors including the profit centers will to generate profits. This leads us to the subject of decision-making in a transfer pricing-systems. On what grounds are decisions made? Are transfer pricing purposes, factors and interests taken into consideration? What type of information is used in such decisions, how is the transfer price issue perceived and how is it used?Aim: The purpose of this thesis is to analyze which type of information that is makes up transfer prices, how the transfer price is perceived by different parties and how it is used for decision-making.Completion: A qualitative study has been performed with current theory as a starting point.

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..

The purpose of this article is to describe the discourse in which public-private partnership (PPP) resides, within the Swedish parliament, in the field of infrastructure. I have chosen to look at the latest three years deliberation where PPP appears in parliament bills.This case study is based upon discourse as a qualitative method. Five indicator signs which is history, comparison, geographic location, vision of growth potential and solution controls the context of PPPThe result of the analysis was that a clear discourse was unravelled. A first rather surprising conclusion shows that it is possible to disconnect the discourse from PPP. PPP is not important by itself, the result shows that it only play the part of possible solution to the problems related to the discourse and does not have any value in its own.This result lead the conclusion that PPP is no more than a tool for politicians to get as much out of their infrastructural aims as possible, as rational vote-maximizing actors.

Abstract The purpose of this essay is to compare in what way pedagogues in pre-school in comparison to pedagogues in school use music as an implement to stimulate children?s language development. The essay is built on qualitative written interviews on four pedagogues, two pre-school teachers and two class teachers, along with relevant literature concerning music in relation to language development.In the interviews it was shown that music is used in a greater extent by the pre-school teachers, compared to the class teachers. Activities containing elements of music is situated on a daily basis in preschool, where the two interviewed pre-school teacher?s works.

This Bachelor?s thesis examines and describes the governmental cultural policy in Sweden. The relation between the state and the market in society is in focus. Earlier research is used to describe the development of cultural policy in Sweden after the world war two until today. Two governmental bills are examined and described, one from 1974 and one from 2009.

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

In our study, we investigated how the streamed TV domain relates to existing design principles for web design. Further, we have investigated whether there are specific characteristics of the domain that the design principles do not cover. In the survey we have studied two sites which are representative of the streamed TV domain. Finally, we discuss how applicable the design principles are for the domain and the specific characteristics that would require new or further developed design principles..

This thesis consists of three parts: one normative, one empirical and one constructive, with the intention to explore the enforcement of accountability in megaprojects.The thesis aims to evaluate the level of accountability in the policy process of the European Spallation Source, ESS between 1990 and 2008. In order to make a comparison possible, a norm is created concerning how a policy process should be designed, with primary focus on openness and participation, to make enforcement of accountability possible. The policy process of the ESS is compared with this norm with the purpose of discovering whether the process contains elements that assure enforcement of accountability. After the comparison is done, it is possible to formulate constructive proposals about how the enforcement of accountability can be improved.The thesis also explores how networks, consisting of actors with particular resources, surrounding the ESS-project affects the form of the policy process, e.g. in shaping the social construction of the aim and purpose of the project.
