Identifiering av områden med risk för fosforförluster genom ytavrinning : metodutveckling med GIS
The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.

Mikroproducenternas påverkan på Elinorr
The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.
Inventering av bergborrade brunnar för dricksvatten i område med risk för salt grundvatten : en utredning av grundvattensituationen i Vreta-Ytternäs i Uppsala kommun
The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.
Solvärme på Utö
The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.
Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).
Business Potential of Software Defined Radio Technology
The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.
Attitudes towards hedging by diversified and non-diversified farmers : a comparative qualitative study
Deregulation on the market for agricultural products leads to a more globalised market with increasing price fluctuations. This, in turn, places the farmer in positions influenced by new risks but also improved opportunities. The farmers are faced by uncertainty in terms of financial outcome. To be able to utilise these new market conditions it becomes increasingly important for farmers to continuously follow the price trend, and to develop strategies how to manage the risks exposed by a volatile market.
Farmers with different conditions perceive risk in different ways. Hence, their risk management behaviour will vary.
Bedömning av utländsk brytning och förståelighet hos personer med svenska som andraspråk före och efter en kurs i svenskt uttal
There is a lot of research made on second language (L2) learning (Jesney, 2004). However the relationship between foreign accent, intelligibility and acoustics within pronunciation tutoring is quite an unresearched area (Thorén, 2008). The aim of the study was to analyze how a course in Swedish pronunciation affected foreign accent, intelligibility and acoustics among L2-learners of Swedish. A total of 41 people participated in the study: 16 L2-learners, 4 native Swedish speakers consisting a control group and 21 perceptual assessors with Swedish as native language. The L2-learners foreign accent and intelligibility were rated by the listeners before and after a course in Swedish pronunciation on an eight-point Likert-scale.
Landskapsideal : hur uppväxtens landskap formar individen
The landscape can be something that you rest your eyes on, something that goes quickly past outside the windscreen or the place for the daily work.
To me, landscape is everything around us ? the city, the field and the forest. But what is landscape for you? What does the idea of the landscape stand for? How does our view of the landscape become influenced of the place where we grow up? And the differences between peoples different views of the landscape ? what does they depend on?
My point of the view for this paper is that the landscape ideals mostly depend on the landscape where you grow up and that it depends less on the differences between the individuals.
As a landscape architect the idea of the landscape is the essential. The more we learn, the more we realize how complex it is, but deep down we always have our own experiences and memories and that shapes our personalities.
Säker och modulär lösning för butiksnätverk: Ett examensarbete för Coop Norrbotten, på uppdrag av ATEA
Mitt examensarbete har utförts på uppdrag av ATEA/Exait i Luleå, för Coop Norrbotten. Målet med arbetet har varit att designa, implementera och dokumentera en ny, förbättrad nätverkslösning för Coop Norrbottens butiker, samt att konstruera en detaljerad utrullningsplan för implementation i produktionsmiljö med minimala driftstopp. Min handledare på ATEA var Leif Häggström, seniorkonsult och specialist på brandväggar och nätverkssäkerhet. Jag har även arbetat nära den huvudansvarige för IT på Coop Norrbottens huvudkontor i Luleå; Per-Ola Björnfot.Kraven som fanns på den nya designen från Coop Norrbottens sida var att säkerheten på nätverket skulle förbättras avsevärt, och att strukturen även skulle göras mer modulär och resurseffektiv. Den utrustning som initialt var tillgänglig för designen var den som redan fanns i drift ute på Coops affärer: ?1x Cisco 1811 Integrated Services Router?1x 3Com 3226 L3 access-switch?1x HP Procurve 1800 PoE-switch?2x Trådlösa accesspunkter från Trapeze (Juniper)Utgångspunkten var, som nämnts ovan, att designen skulle baseras enbart på befintlig utrustning.
Månadskostnader vid investering i ny bostad : En jämförelse av olika investeringsalternativ och deras ekonomiska påverkanvid införskaffning av ny bostad.
This is a work that look at the factors that affect future monthly costs when buying a house in Sweden and which options are the most financially favorable over a 30 year period. The work also examines whether it is economically beneficial to invest in a low-energy house regardless of geographic location in Sweden, and discuss about whether a calculation template can help individuals to choose more environmentally friendly options. The work has been limited so that a certain number of predetermined factors and its measurable values have been developed with the help of a literature study. The factors chosen are building type, climate, heating systems, loan interest rates, energy prices, energy price increases, inflation rates and down payment. These are then combined into 72 different calculation cases which get put in a calculation model made in excel.
GIS-modellering av habitat för vitryggig hackspett (Dendrocopos leucotos) som hjälpmedel i naturvårdsplanering på landskapsnivå :
The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.
Svenska mejerier stärker positionerna : incitament för lansering av lågprismjölk
The competition in the milk industry has increased during the last couple of years. This is a result of the trade barrier that dissolved when Sweden entered the European Union. The membership signifies an increased internationalization for the dairies, which has also increased the existence of low price chains in the Swedish food market. The increased share of private brands has strengthened the competitive situation for the manufacturer- owned brands. Three of Sweden?s seven largest dairies have now decided to launch a low price milk to cope with the competitive situation.
