Finansiella garantier - en möjlighet att säkerställa ett miljömässigt omhändertagande av uttjänta produkter
Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.
Hybriddrift i stridsfordon, fördelar och nackdelar
Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.
MIMO kanalmodeler
The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.
Skönlitteraturens genrer: En analys av två universella klassifikationssystem
The main aim in this Master thesis is to analyse how an ideological view may have influenced the shape of hierarchies with a specific concentration on the concept of fiction genre in the latest versions of the systems SAB and DDC. Our thesis is that no theoretical classification scheme can be recognized as objective. With an ideological/institutional perspective we look at the structures behind these systems. As a vehicle we use the hermeneutic circle to show the play between part and unit by focusing and analysing three different levels: the content level the concept level the ideological level. The first level is in the shape of a historical background and an analysis of concept with focus on content.
Ekonomistyrningens påverkan på MRP-implementering: en fallstudie av ASSA AB
The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.
VINDKRAFTSETABLERINGAR : EN JÄMFÖRANDE STUDIE OM NÄRBOENDES INSTÄLLNING TILL VINDKRAFT OCH VINDKRAFTSETABLERINGAR I SVERIGE OCH BRASILIEN
To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.
Offentlig konst och offentlig makt
The main purpose of the culture is to serve people and represent the people's social will and freedom. Culture does not exist in a vacuum but shaped and framed by political and artistic structures that are not neutral, and this is why the artwork itself cannot be an independent business. The public function of art can be understood as a defense of the ideals of democracy. But today, when political power is often replaced by hegemony, the role of art and functions are changing. How these changes reflect to the identity, reality and truth of society? What political functions are fulfilled when art becomes ?public?? The issue of democracy is linked question of people?s power in a democratic society where power is legitimized in social space.
Dokumentation av underhållssimulatorer för utbildning i vardagssäkerhet
At Forsmark nuclear power plant a new course called "education in everyday safety" has been started in an attempt to improve the safety culture. The goal is to spread the of expectations and approach the maintenance management has set, to all employees working at the plants. During the course, theory is mixed with practical tasks to reach a common view how work should be done to achieve safety for the plant and the people that work there.The practical tasks are done inside "maintenance simulators". They are built inside 20 ft containers which contains two dummy pipe systems. On the pipe systems some valves, a flow meter and a pump has been installed.
Trossamfundens makt i Sverige : En uppsats om stat-kyrka reformen och dess inverkan på trossamfundens maktposition
The aim of this paper is to describe and explain how the separation between state and church effects the power relations between state and religious groups and organizations. Former state church, The Swedish church, is in this paper, not included in the definition of religious groups. The reform (?stat-kyrka reformen?) took place between 1995 and year 2000.I?m examining if religious groups had any influence on the reform. My expectation is to give a clearer picture of religious groups and its power position in Swedish politics and society.
Homosexualitet i tre klassifikationssystem under tre decennier: Ett queerteoretiskt perspektiv på SAB, UDK och DDC.
The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.
Medier, makt och rasism : En kritisk diskursanalys av svenska nyhetsmediers rapportering om Rinkeby
The aim of this thesis is to examine expressions of power and racism in news reporting about the district of Rinkeby, Sweden, in two major Swedish newspapers. News articles are examined using Norman Fairclough?s three-dimensional model for critical discourse analysis. The discourse theory has also been complemented with theories of media in relation to power, ideology and racism. The study has shown that news reporting about Rinkeby largely focused on stereotypical subjects such as violence, social problems and crime.
EN FALLSTUDIE OM URBAN VINDKRAFT VID ALBANO
The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.
Att skilja äpplen från päron : en studie om belöningssystem
Companies today need to be more focused than ever on having an active Human Resource Management culture. This is not only because of the companies? concern for their staffs wellbeing, but for the companies? effectiveness in the long run. The reward systems which many corporations use today, to both keep their employees and attract new ones, is a well researched subject by scholars as well as journalists. Earlier research has suggested that it is important to implement an active Human Resource Strategy.
Vattenrådens roll i vattenförvaltningen : Ett myndighetsperspektiv på lokalt deltagande
The purpose of this essay is to illustrate how the position of power / exercise of power are perceived in today's schools from the teacher's perspective. I have examined how students' freedom and democracy education interpreted in real life, and how this affects both teacher and student learning approaches. I would also highlight the need to set standards for children's psychological development related to the consequences will be. I have chosen to perform a qualitative research through individual interviews with five participating teachers from different experiences in different type of school. I have used the hermeneutic method of analysis to analyze the material.
Undersökning av ögats brytningsförmåga i ett svenskt hästmaterial :
Skiascopy, also called retinoscopy, is a method for determining the refractive power of
the eye. There are only a few, old studies made on equine refraction. The aim of this
study was to investigate the refractive power in a population of Swedish horses.
The study consists of a review of relevant studies done on animals and an experimental
part where the refractive power of 93 horses of different age, breed and usage was
examined. A pilot study of 12 horses was performed regarding the importance of
cycloplegia when doing skiascopy on horses.
The results of the pilot study show no significant difference in the skiascopy results
between the group before and after cycloplegia were induced. Consequently, there is no
need of inducing cycloplegia before doing skiascopy in adult horses.
The study shows that horses usually were emmetropic (normally sighted) with minor
deviations toward myopia or hyperopia.
