Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.
Komponentuppdelning av elnätetpå lokalnivå
Sweden will, in accordance with the EU-directive 2003/54/EC, move from post-regulating the electricity power grid-tariffs by using a fictitious grid, to a regulation in advance which uses the actual power grid as a starting point. For this purpose a component breakdown of the grid needs to be made to determine the value of the network and by that the tariff price that is reasonable for the network business in question to charge.The primary breakdown criteria is the voltage-level and type of region. Voltage-level is crucial for the cost and complexity of a grid-part, because the higher the voltagelevel is, there are more and stricter laws and rules to follow. This work is limited to the distributionpart of the grid, in other words voltage levels from 20 kV and below.The type of region is crucial to the type of components you can and want to use. In city environments both overhead-wires and independent substations are undesirable for both practical, safety and aesthetic reasons.
Rapport och Nyheterna : - innehållsanalys av deras gemensamma nyheter
The purpose of this paper is to investigate contents in the news in order to search for similarities between the two television news reports, Rapport and Nyheterna. The news features that I examined in my investigation were broadcast in April and May 2006.SVT and TV4 are two Television channels both belonging to the analogue television network in Sweden, which means that they reach out to almost the whole country. Hence I thought it was interesting to investigate their reports on similar news.The question:- Which are the similarities and differences between how the two programmes describe their reporting on similar news?When I put together the information from the two programmes in the schedule I based my analysis on the following questions: topic, place, length, type of reporting and per-sons/sources.The method for this investigation is a quantitative content analysis. However, some part of the collection of information and description/interpretation of the material is qualita-tive.Rapport and Nyheterna had an average of 15 similar news features per week, of which foreign news dominated.

Methodology: The researchers have decided to take a phenomenological standpoint and undertake an exploratory study in order to gain understanding of the phenomenon of market entry and the use of networks. The researchers have chosen to undertake a qualitative study and to adopt an abductive approach. Two ?case companies? have been chosen which are Filippa K and House of Dagmar.
What to expect ? A qualitative study of roles in Retail Marketing
Thesis purpose: The purpose of this master thesis is to investigate the expectations of roles between supplier sales representatives and retailer store personnel in relation to in-store campaigns, this in order to enhance effectiveness of these functions creating an increase in consumer response. Methodology: The researchers believe that social phenomenon and their meanings are continually being accomplished by social actors, hence a study of individuals? expectations must have a point of departure in these people?s social reality. Store personnel and supplier sales representatives are to a certain degree affected by the structural power relationships within the organizational network, thus the researchers combine an interpretative and radical structuralist paradigm. Theoretical perspective: The researchers investigate expectations of roles through examining interaction between parties involved.
Landsbygdsturism och dess förutsättningar : en jämförandestudie kring vilka resurser som krävs för ett framgångsrikt entreprenörskap
Many jobs in rural areas have historically been linked to the agricultural sector. The restructuring that has been implemented in agriculture has resulted in a significant reduction in the number of jobs in rural areas. A consequence of this is that many people have moved to cities to earn a living. To maintain a living countryside in Sweden, it is therefore essential to create alternative livehoods in rural areas. An industry that can have a major impact in the future is rural tourism.
Ny princip för spänningsreglering i Fortum Distributions mellanspänningsnät i Stockholm.
The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.
Teknikens roll i en digital valuta : en studie om användarnas förtroende för bitcoin
Bitcoin is a digital currency that is used by people all around the world. The goal of this paper is to give an idea about how much trust there is in bitcoin among its users. This paper has used an online survey aimed at bitcoinusers and a content analysis to collect data about this trust.The conclusions show that there seems to be some trust in bitcoin as a technology and this is based on that the users have a good understanding about how bitcoin works. They also share their knowledge about bitcoin to people around them. The trust between people in the bitcoin network on the contrary doesn?t seem as high because certain technological properties hurt this trust.
Analys av mätdata från nätstationer
Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.
Lan File Share : Ett fildelningssystem åt Försvarsmakten
The Swedish Armed Force has a need to streamline the preparation of an exercise in tactical training for soldiers because the preparation of an exercise is currently laborious and time consuming when commanders manually share files to each computer that will be included in the exercise. The degree project was to create a file sharing program within the internal network of the Defence Forces? international centre (Swedint). The program is used by the training management to effectively start up an exercise where soldiers train tactical training in a simulated combat environment. The training management use this program to upload files to a server which notifies all the computers on the network to download these files.
Quadrotor UAV : Konstruktion och användbarhetsstudie av en UAV i sensornätverk
Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.
En situerad ansats för utvecklingen av en räknande robot
Den situerade ansatsen inom artificiell intelligens har i tidigare experiment visat på stora möjligheter vid utvecklingen av enkla beteenden. Ansatsens framgångar är dock inte lika tydliga när det kommer till utvecklingen av mer komplexa beteenden som i högre grad påminner om de experiment som gjorts inom traditionell artificiell intelligens. I studien utvecklas en agent med ett ?Extended Sequential Cascaded Network? som kontrollarkitektur för att lösa en uppgift som kräver ett ?räkneliknande beteende?. Utvecklingen av nätverket grundas på en situerad syn på kognition, däribland att designern i så liten grad som möjligt skall styra utvecklingen.
"Are You Gonna Go My Way?" - En empirisk studie av Västra Götalandsregionen lobbyverksamhet och nätverkan i EU
In this thesis we have examined Västra Götalandsregionens ways to lobby and network in the European Union. Our aim was to examine which kind of methods the region uses to lobby in a successful way in Brussels. We found that the region uses both formal and informal methods of lobbying to gain advantages in Brussels. We also wanted to locate various networks which the region is involved in to more easily have their interests satisfied. We found that they had a lot of different alliances and that it is necessary to be involved in different networks to have a chance to lobby the EU institutions.
Tillit i moldavien
Moldova is one of Europe?s poorest countries with a struggling business environment and an unpredictable political situation. The purpose of this thesis is to understand the implications of corruptions and why networks have come to play a key role in the Moldovan culture and if the formations of network are due to heritage or an effect of functionalism. The focus of the study is also to explain how the networks develop and the formation and maintenance of loyalty and trust among the members of the network. The study is of a qualitative nature that uses a key informant sampling method to get access to members of different business networks.
En heterotopologisk analys av den kulturella infrastrukturen i Göteborg: Rio Rio-båten på kollisionskurs med ett stadsplaneringsmaskineri på drift.
This essays overarching aim is to contribute to the theoretical discussion of transformation processes that are shaping the urban landscapes and further to problematize contemporary planning discourses in Sweden. Drawing on the concept of Foucault?s heterotopia and actor-network theory for spatial analysis, the paper seeks to analyze the complex urban landscape transformation process as an emergent property of human and non-human actor-networks seeking to transform and order space. With the district of Rosenlund in Gothenburg as a starting point, this thesis intends to examine how the cultural infrastructure - used by the residents and visitors of the city - are related to the city's planning and development processes. The case study is based on a boat (Rio Rio) in Rosenlund canal that is defined as a cultural infrastructure.
