Hantering av småskalig elproduktion : Utveckling av modell för dokumentation och elkvalitetsberäkningar

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

Vetenskaplig publicering i förändring ? En fallstudie av en svensk högskolas implementering av ett öppet digitalt arkiv

Since the beginning of the 21st century the Open Access-movement, which advocates free online distribution of scholarly information, has gained momentum. Authors can provide Open Access to their work in two main ways: by depositing a copy of their research output in an e-print archive and by publishing in Open Access journals. During the past few years, universities and other research institutions throughout the world have established institutional repositories to manage, preserve and provide access to the intellectual output of the university/research institution. The purpose of this master?s thesis is to describe the implementation of an institutional repository at the Swedish University College of Borås.

Energibolagens framtida datainsamling

The Swedish energy companies have several different systems for data collection of the energy consumption of their clients. Often computerized remote meter readers are put in practice in order to register the energy consumption of large companies. The majority of household clients, however, are read off by the assistance of manual methods. Household power consumption is read off once a year. As a result, these clients are not debited for their actual consumption; their invoices during the year are the result of estimations. At times when the electricity supply system is highly loaded, electricity is more expensive.

Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

Konkurrensfördelar på en marknad som karaktäriseras av offentlig upphandling

Background: It is necessary for a company to hold some unique and irreplicable competitive advantage in order to be able to succeed in a market. In a market where public procurement is an important part the competitive advantages will be characterized by the fact that some of the participants on the market are public organizations and that their actions as for procurement fall under the legislation LOU. The characteristics of competitive advantage also depend on and change with continuous changes on a market. Purpose: The purpose of this thesis is to study the competitive advantages that are presenton a current market characterized by public procurement and how these are created. The purposes is also to based on the trends on the market today study and predict the nature of the competitive advantage on the market in the future as well as the changes that we think will occur on the relevant market.

Habitat use and ranging behaviour of GPS tracked juvenile golden eagles (Aquila chrysaetos)

Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until migration. The juveniles fledged at the end of July and beginning of August and initiated migration during October and beginning of November. The length of the post-fledging period, until migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.

Skapandet av ett byggnadsfysikaliskt detaljbibliotek åt byggnadskonstruktörer : fokus på fukt- och värmetillstånd  i köldbryggor

Det konstrueras i stor utsträckning bristfälliga detaljlösningar på byggnader i dagsläget. Den bärande stommen i konstruktionen prioriteras ofta medan det inte ägnas lika mycket fokus åt att tillgodose de byggnadsfysiska aspekterna. Anledningen till de bristfälliga detaljerna är även att den som utför arbetet saknar rätt kunskap och tid. För att skapa en förbättring behövs ett hjälpmedel!Kunskap och erfarenhet om hur bra detaljer skapas finns redan i företag, svårigheten är dock att sprida kunskapen till de som är i behov av den.Målet med denna rapport är att skapa en metodik som blir startskottet för ett omfattande arbete kring framtagandet av ett detaljbibliotek, vars syfte är att sprida byggnadsfysiska kunskaper inom företaget och inspirera konstruktörer till att konstruera bra detaljlösningar. Biblioteket ska innehålla byggnadsfysiskt utredda detaljlösningar som analyserats enligt den utarbetade metodiken.

Kunskap om skaderisk och preventiv träning vid främre korsbandsskador bland tränare för 14-15-åriga fotbollsspelande flickor: En enkätstudie

Fotbollen är en av de mest skadedrabbade sporterna i Sverige. ACL-skada är den allvarligaste knäskadan med en lång rehabiliteringstid. Det har tidigare rått oenighet om förebyggande träning haft någon effekt på om en skada kan förhindras. Senare års forskning har visat att förebyggande träning har god effekt för att förhindra dessa skador. Undersöka kunskapen om förebyggande träning för att undvika främre korsbandsskador, samt undersöka kunskapen om skaderisken för främre korsbandsskador bland tränare för 14-15 åriga flickor inom Norrbottens, Göteborgs och Skånes fotbollförbund.

Den heliga treenigheten : en fallstudie av kommunikationsprocessen mellan ledning, anställda och säljbolag på Alfa Laval AB

The manufacturing industry is currently in a short-term downturn while the competition is increasing. The result of this is that companies must find new ways to bring out their products. Traditional competitive strategies, such as low pricing, is not sufficient today as the customer is inquiring something more than just a good product. Higher demands are presented on an accurate, well functional, communication between customer and companies, as this has become an important strategic factor in achieving long-term profitability.The aim of this independent project was to analyze and evaluate the communication process between a company and its sales companies.In order to illustrate this process, a case study was carried out at Alfa Laval, their sales companies and employees at their distribution center in Tumba. In order to see the differences in attitudes between the management, the sales companies and the employees regarding communication and involvement a gap analysis were used.The theoretical part of the study considers theories about business mission, communication, involvement, quality and creating value.The result showed that a smaller gap exists between the sales companies and the management while a slightly larger one exists between the employees and the management.

Utvärdering av klusteranalytiska metoder i kombination med bibliografisk koppling: en bibliometrisk kartläggning av aktuella forskningsteman inom informationsvetenskap

The purpose of this thesis is to evaluate the combination of bibliographic coupling and three hierarchical cluster analytic techniques: average, complete and single linkage. Bibliographic coupling is applied as a measure of similarity between recently published articles and the cluster techniques are used for the partition of a set of articles into subsets of articles with similar research focus. The field of information science is applied as the test arena and the selection of data, i.e., the article population to be partitioned, is based on a number of central journals. Methods of evaluation include both quantitative approaches as well as a qualitative one. For comparing the resulting partitions, adjusted Rand index is utilized and for the establishment of cluster coherence and isolation, measures of average normalized coupling strength is applied.

Kirunametoden-Jämförelse emot en konventionell injusteringsmetod

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.
