Faktorer som påverkar vindkraftsutbyggnaden
Wind power is expanding rapidly in Sweden. Increasing amounts of wind power sets higher requirements on balancing power and grid expansions and would affect the whole Swedish electricity system. The aim of this report is to examine the factors affecting the wind power expansion in Sweden. How many wind power plants projects will obtain building permissions and what costs and revenues can be expected? How much balancing power will be required and does a changing geographical distribution of the wind power plants reduce the need of balancing power?A survey of the county board?s official applications has been made and out of all the applications, corresponding to 80 TWh produced per year, about half of the applications are expected to obtain a permit with a major portion of them located in the north of Sweden.Especially older wind power plants, deriving revenue from Nord pool, find themselves today in a complicated financial situation.
Alternativa drivmedel i den svenska vägtrafiken år 2030 : En utvärdering av den svenska regeringens målbilder
The Swedish government has set up the overall goal that no net emissions of greenhouse gases can occur after 2050. A sub-target has been developed for road transports which states that the use of fossil fuels must be reduced with 80% to 2030 in order to be completely abolished to 2050. A public inquiry mapping how this can be achieved was handed in to the government late in 2013. The use of alternative fuels for road transport, both biofuels and electricity, is expected to give the biggest contribution to the reduction of the use of fossil fuels. The inquiry sets up a number of goals for how much the use of alternative fuels must increase to 2030 in order to reach the overall goal and which instruments that are needed in order to do so.The aim of this thesis is to evaluate how these goals can be reached and what the most likely obstacles that may hinder the reaching of these goals may be.
Patientrörlighetsdirektivets inverkan på svenska patienters möjlighet till gränsöverskridande vård : har förutsättningarna för hälso- och sjukvård i annat EU/EES-land förändrats sedan direktivets införande i svensk lagstiftning?
Most of my 16 students show a negative attitude towards mathematics and have difficulty understanding why they need mathematics to work as cooks. Their lack of knowledge has a negative effect on their work in the kitchen because they cannot master relatively simple mathematical solutions. The purpose of this study is to examine if an integrated working method of the subjects mathematics and cooking can change students? attitude towards mathematics and increase their understanding of the value of it in restaurant work. An integrated working method means to integrate the core subjects with programme specific subjects and that teaching is directed towards the main features of the vocational programme in order to create a holistic view.A theory of action research has been applied in this study, aiming to change something perceived as problematic through combining theory and practice in the cooking subject.
Småskalig elproduktion i Arvika
Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.
Solel och solvärme ur LCC-perspektiv för ett passiv-flerbostadshus
This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.
Digitala bibliotek - framtidsvision eller morgondagens verklighet?
In the wake of the electronic revolution digital library has become one of the central themes concerning libraries. The present study takes up the question whether digital library can function in the same way as the conventional library. The question can obviously be posed from different perspectives, e.g. technological-, the user-, or the organizational perspective. The study investigates if (and how) digital library can have the same functions as the traditional library.
Elektromagnetisk och mekanisk design av en 20MW turbogenerator
At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.
Kompostering av organiskt avfall från Gästrikeregionen ? miljöpåverkan av olika behandlingsalternativ
In the coming years, organic food waste will be collected in the region of Gästrikland, Sweden. The collection is planned to cover the entire region by the end of year 2007. To start with, smaller amounts are being collected and transported to a central composting plant in Sala. However, a central composting plant in the region of Gästrikland is projected.The objective of this thesis is to evaluate a number of possible methods for composting of organic food wastes regarding their environmental impacts and localization.There are four scenarios for future composting of organic waste that have been evaluated. There are two that consist of membrane composting, either in Sala or in the region of Gästrikland.
Hyllie vattenpark : ett gestaltningsförslag
This project is focusing on a future park that will surround Hyllie water
tower in the outskirts of Malmö. The water tower will be located in the
central part of the new building area Hyllievång. The park will function
as a town park with a special focus on water. The water council of the
municipality, Va-verket, has for the last 7 years built up and been in
charge for a pedagogical programme in the water tower, were schoolchildren
come to learn about the cycle of water and how we use water
in our daily life. In the park they want to build a new part that gives
experience of water, as a compliment to the information in the tower.
What will that park look like, and what shall it be constructed of?
How do you bring water to the surface in a park? How can landscape
architecture work to enhance the presence of water and make people
more interested in water issues? In the search to find the answers to all
my questions I have meet with people, read books and visited different
places.
?Dom som mår dåligt måste få må bra? : En studie av skolintroduktionen för nyanlända flykting ? och invandrarbarn på två skolor
Subject: The Teacher Training Programme, Degree Project in Educational SciencesSödertörn University CollegeAutumn Term, 2006This study titled, Those who feel worst, need help to feel better, is a Degree Project in Educational Sciences for the Teacher Training Programme at Södertörn University College. The purpose of this study is to find out how school introduction for newly arrived refugee children is organized in two schools, considering the fact that many refugee children can suffer from PTSD, Post Traumatic Stress Disorder. The study is qualitative, based on interviews with principals, teachers and students in one junior high school and one high school. The study also reviews literature and research on how to work with children who suffer from PTSD. The results show that lack of national policy for the school introduction and education of refugee children, leads to the fact that school introduction can vary from school to school.
