Analys och organisering av ö-drift för en samförbränningsstation vid Åmotsfors bruk
Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the
manufacturing of paper. Unpredictable energy prices and modernisation of the current
equipment has been the underlying factors to invest in a thermal power plant, mainly
driven by garbage. This facility will not only use the steam for paper production, it will
also generate electricity through a steam turbine. Today, when a fault on the supplying
line occurs which leads to disconnection of the external grid, all the support of electricity
to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper
production, which will cause severe economical losses.
Lantbrukares möjlighet till en investering i solceller
When the costs for a company increase it is normal to look for alternatives to lower thesecosts. One of the expenditure that farmers have is energy costs. The price for the energy mayvary because of the free market. To look at the possibilities for a farmer to invest in sunpower, to make the company less sensitive for the changes on the electrical market, isinteresting. The biggest part of the electricity that is produced in Sweden comes from a fewcompanies on the market.
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.
Det Intelligenta Huset : - En studie i hemautomation
Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.
Rätten att benämna : Maktutövning i Amalie Skrams psykiatriromaner
Amalie Skram (1846-1905) was born in Norway but lived in Denmark. She published several books about gender relations and built up a reputation as a naturalistic writer. In 1894, a nervous breakdown made her seek help from the famous psychiatrist Knud Pontoppidan. He sent her to an asylum, but she returned home after spending two months in psychiatric care. In 1895, Skram published two novels about the painter Else Kant, based on her own experiences but not written as autobiographies.
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.
Konceptuell modell av dataomvandling till USB
Alstom Power i Växjö arbetar med utveckling och försäljning av bland annat elektrofilter tillrökgasreningssystem vid olika typer av miljövårdsanläggningar för t.ex. kraftverksindustrin.Dessa elektrofilter kontrolleras och regleras med hjälp av styrutrustning uppbyggd av ettantal styrenheter som idag kommunicerar via en egentillverkad standard kallad ?Fläktbuss?. Föratt övervaka detta system vill man använda handburna PDA och kommunicera med Fläktbussenvia USB. För att få kommunikationen mellan USB och Fläktbuss att fungera krävs någon form avaktiv konvertering.Detta examensarbete kommer att ta upp så väl problematik och lösningar kring detproblem som finns i samband med denna konvertering..
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.
Birgitta - Helig eller helgalen? : Kan Birgitta Birgersdotters mystika gudserfarenheter ha sanningsanspråk?
Prisons are for many an unknown world, and few know about the prison culture which includes unwritten rules, power structures, interactions and relationships between inmates and correctional employees.While many think that Swedish prisons are too comfortable,inmates are facing extreme stress due to surveillance and detention, by depriving inmates their possibility to shape their own lives. When the inmates is deprived of control over their own life?s the penal system have great power to shape and to influence the inmates.The purpose of this paper is to investigate prisoners' experiences of treatment and exercise of power in prisons. Starting point is to examine what are the kinds of relationships between prison officers and inmates from a power perspective, if there is any difference between the closed and open prisons and how the inmates affected by the structures that exist.Based on my overall purpose, and with my informant´s stories which revealed a number of similar points, four main headings were developed; Mass media and society´s view, and unknown world, interaction between inmates and prison officers and consequences.Prison officers with the role as a contact persons as well and other staff which work close to the inmates play a significant role by supporting through motivational interviewing and can help the inmates to gain insight about their life situation and actions. My informant?s underlined that a good contact person can either help or discourage.Inmates who contributed with their experiences express that there is a big difference between open-and closed prisons.
Strategi för utvecklande av reglerbudata
This Master Thesis discusses the development of bids for regulation power with consideration of change of discharge. The study was initiated by Vattenfall PD and is a limited part of a substantial development project at the same division. The background of the project is the new demands from SvK, which among other things includes more detailed regulation bids. As from the 1st of November 2008, the regulation bids are supposed to be calculated regarding each specific regulation object, something that is defined by SvK. These new demands changes Vattenfall?s conditions and will increase the need for detailed knowledge about available regulation power and costs for regulation.In this study a strategy for regulation bids was developed.
Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn
The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.
Den bristfälliga implementeringen av LSS en studie av maktaspekten i mötet mellan socialtjänsten och människor med psykiska funktionshinder
In this study, the aim is to show how the social services fails to implement a specific rights law (LSS) wich is supposed to have the function of protecting the wellfare and provide specific rights to people with severe mental disabilities. By applying chritical theory on this case the aim is to provide an alternative answer on why it is possible for the social services to ignore these peoples rights.By revealing the power structures in the encounter between the system and a person with mental dissablilities, I conclude that people with mental disabilities does not fit in when it comes the social sevices way of implementing the law and further more that a private person is extreamly exposed to the systems arbitrariness..
"Lite snyggare, lite mer partyaktiga, lite mer Paradise" : En kritisk diskursanalys av kön och sexualitet i Paradise Hotel
The purpose of this thesis is to examine how power structures concerning gender and sexuality emerge through the use of language in the Swedish reality show Paradise Hotel. Of particular interest is the representation of heterosexual relations in the show. Because of its interest in the relationship between power, gender and sexuality, the thesis is based on theories from gender and discourse studies. The specific theories referred to are Michel Foucault?s understanding of power, stereotypes according to Stuart Hall, Yvonne Hirdman?s gender system and contract theory, Judith Butler?s heterosexual matrix and R.W.
Damned if you do, damned if you don´t
The purpose of this paper is to explore the social worker?s perspective on working for the government as a professional in care of children, in relation to the family's right to self determination. The essay's empirical material is gathered from qualitative, semi-structured interviews with social workers who work with children and youth in communities and districts in Skåne and Stockholm City, Sweden. The analysis was conducted in line with theories of social constructivism. The results and analysis show that the interviewed social workers did not believe that the state has too much power over the citizen.
Varför dela makten? En studie av consociationalism och Democratic Unionist Partys beslut att delta i regering på Nordirland.
On the 8th of May 2007 a local power-sharing goverment consisting of Sinn Fein and the Democratic Unionist Party (DUP) was formed in Northern Ireland. The aim of this dissertation is to explore why the DUP, who in the past have opposed all forms of power-sharing decided to form a goverment and take active part in a power-sharing agreement. The study is based on a consociational theoretical framework developed by Arend Lijphart and further developed in a Northern Irish context by John McGarry and Brendan O'Leary. Using this theory the study seeks to understand the broad conditions surrounding the DUP's power-sharing. After a description of consociational theory and the road leading up to the Belfast Agreement,three possible explanations for power-sharing, based onconsociational theory are discussed.
