Utvärdering av labpilot - flödesbatteri : Experimentell studie

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

Analys och kvantifiering av energieffektivisering inom fjärrvärmesektorn

The Swedish Government has set a target to reduce energy consumption through energy efficiency within the construction and real estate sector. The purpose of the study is to examine how energy efficiency within this sector could affect the district heating volume in the future, on basis of Vattenfalls district heating system in Uppsala.An Excel model has been created to study how energy effficiency measures affects district heating demand in buildings by 2045, based on technical and economicalconditions. Furthermore, an interview study has been conducted to examine incentives for district heating customers to invest in energy efficiency measures.Result of the Excel model shows that the district heating volume of Vattenfall in 2045 is expected to 931 GWh, which corresponds to a volume decrease of 10,6 %. Based on the study?s theoretical framework only 15 %, 1 024 GWh, of the technical-economical potential is assumed to be implemented.

A targeted evaluation of OpenEye?s methods for virtual ligand screens and docking

The process of drug discovery is very slow and expensive. There is a need for reliable in silico methods; however the performance of these methods differs.This work presents a targeted study on how the drug discovery methods used in OpenEye?s tools ROCS, EON and FRED perform on targets with small ligands. It was examined if 12 compounds (markers) somewhat similar to AMP could be detected by ROCS in a random data set comprised of 1000 compounds. It was also examined if EON could find any electrostatic similarities between the queries and the markers.

Lönsamheten av analytikers riktpris - En studie av svenska bolag handlade på Stockholmsbörsen

We acknowledge the lack of empirical studies of the performance of analyst target prices in the Swedish stock market by examining the profitability of target prices for stocks publicly traded on the Stockholm Stock Exchange. We use consensus target prices issued between 2006-2010 and create two different strategies to observe the abnormal returns generated during this period. Going long in the top decile stocks with the best target prices and going short in the bottom decile stocks with the worst target prices generates a statistically significant abnormal buy-and-hold return of 8.9%. An active strategy with daily portfolio rebalancing and a timely response to target price changes generates a less significant monthly alpha of 1.4% against CAPM. The results show to be robust against the size effect discovered by Fama and French.

Kraven som inte infriades - Efterlevandet av regeringens och Riksrevisionens krav inom kontrollverksamhet och kvalitetsgranskning hos Försäkringskassan i Skåne

This thesis is dealing with the programs of control regarding deceit and quality assurance within the Swedish social insurance administration in Skåne, the years 2002-2005. In 2005 the Swedish National Audit Office released a report regarding the lack of measures towards deceit and fraud, and the lack of quality in the data for decision making within the administration. The questions to be addressed are why the administration does not make up to the demands regarding quality and measures towards deceit that the government and The National Audit Office demands. The main source for data has been interviews with workers within the administration and annual reports from public authorities. To understand and be able to explain the problems within the administration the theory by Michael Lipsky regarding street-level bureaucrats is used.

Vogler och pergolesis stabat mater: En väg till historiskt informerad uppförandepraxis

The author is active as a musician in the field of historically informed performance practice (HIP) which emanated from the 20th century early music movement. Studying of historical sources has a central role, but the problem of how interpretation and selection of source material is affected by art and music ideals of our time, is commonly acknowledged. Georg Joseph Vogler shows in a series of articles in "Betrachtungen der Mannheimer Tonschule" (1778-1781) how Stabat Mater by Pergolesi could, and in his opininon, should be improved. The purpose of this thesis is to investigate how this source can be used from the standpoint of a performing musician: How can I use Vogler?s methods in my playing?The introduction problematizes Vogler?s action in relation to his time, and to ours.

The essay conducts a comparative study of the two legislations and seeks to determine whether Article 7 of the Swedish law of public administration is consistent and compliance with Article 6.1 of the EU Convention.

Analysis of Quality of Service of Wireless LAN for IEEE 802.11e

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

Uppfödning av gyltor till hållbara suggor

Half of Sweden?s 140 000-150 000 sows are culled and replaced by 75 000 gilts annually. Culling of old sows is necessary and allows new breeding material to enter the herd. However, many of the culled sows are young, and have not yet become profitable at the time for culling. Therefore, it is an important question for the pig industry, how to raise gilts to sows with a high and sustainable production level.

Stockholm temporary : relevancy & potentials for implementing temporary architecture in Stockholm

Temporary architecture is an alternative urban planning concept which has been adapted in many cities worldwide during the last decade. There is however no common definition for temporary architecture and it is diversely labelled and applied. In 2013 it also became publicly introduced in Stockholm via the approval of the city's first architectural guideline. Temporary architecture is presented in the guideline as a potential tool for exploring public spaces among other architecture related themes. The ideas for temporary architecture are ambitious and promising. The problem is that they are vague and leaves questions regarding performance unanswered.

Prestationspåverkan av flerträdshantering i klena gallringar

The aim of this study is to investigate how multiple tree handling harvesters perform compared to earlier developed standards. The study shows that multiple tree handling harvesters are more efficient in thinnings stands with mean stock volumes less than 0,12 m3fub per stock. The increased efficiency is different for different mean stem classes. In stands with a mean stem volume of 0,04 m3fub per stock, the increase can be as high as 40 percent while it is about 10 percent in stands with a mean stem volume of 0,12 m3fub. Comparisons have been done between stands that are felled with partly limbed stands and stands without partly limbed assortments. The difference in performance is clear and shows that the partly limbed assortments strengthen the multiple tree handling harvesters positive effects in low dimension thinnings.

A risk analysis of moose close to roads

For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.

Belastningsskador vid montering : Påverkan på svensk tillverkningsindustri och hur effektivt förebyggande kan bedrivas

AbstractAccording to research made by Statistics Sweden on the members of the labor union IF Metall the number of reported musculoskeletal disorders for employees working under the collective bargaining agreement for the automotive industry has almost doubled since 2003. During 2004- 2006 and 2008 male assembly workers were the occupational group with the highest amount of reported work related disorders in Sweden. To prevent musculoskeletal disorders is according to Rose and Orrenius important both for the individual, the society and the industry by reducing economic and personal costs. The purpose of this paper is to identify and analyze how the manufacturing industry is affected by musculoskeletal disorders that occur when working with line assembly and how companies can prevent them. The report aims to provide the reader with an understanding of what musculoskeletal disorders are, to which extent they occur in assembly, how companies are directed by laws and regulations and how they affect the Swedish manufacturing industry and their employees.
