Intelligent remuneration in the knowledge economy
Talented people are recognised as being the most important corporate resource over the next twenty years and a competitive compensation system is an important tool in attracting and retaining talent. Traditional pay systems are recognised as being neither cost effective nor motivating people to do more. Often these systems do not contribute to strategic objectives. This study outlines what constitutes an intelligent remuneration system that will enhance the mind value added by knowledge workers, reward knowledge creation, and contribute to organisational strategies..
Momentfördelning i pelardäck av armerad betong
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Energibalans Dåva Kraftvärmeverk
To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.
Modellbaserad systemutveckling i komplexa verksamheter. En fallstudie av Coremetoden
In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.
Drömsymboliken hos Boles?aw Lesmian : Kommentarer till dikter ur samlingen ?????? ????????
Anne Reese: Johan Lindegrens vägval : en studie i de faktorer som påverkade enskilda aktörers verksamhet inom Stockholms musiksamhälle 1860-1908, Uppsala universitet: Institutionen för Musikvetenskap, uppsats för 100 poäng, 2007.The aim of this essay is to show some of the factors which affected the production and work of the individual musician or composer within Stockholm's music society in the late 19th century. By a case study on Johan Lindegren (1842-1908) I demonstrate how a musician or a composer functioned in the social structures of the music society and how power affected the work of the musician or composer. This essay also fills another purpose as it gives Lindegren a more detailed biography, which is something that has been missing until now.By applying a concept of power, as discussed by Michel Foucault, to this subject and interacting it with the concepts of musical opportunism, I present a new way of talking about the social, as well as the individual factors that affects the individual musician within the music society.The conclusion is drawn that there are two different types of factors that affects the work of the individual; 1) the social network and power within society, which presents positions and opportunities for the musician and 2) the individual character of musician which determine the way the individual uses the position or opportunity he or she is given..
LAN-Uppgradering
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.
Primärenergianvändning av passivhus i Sverige : Med fokus på Kvarteret Trettondagen
The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.
Vad räknas som mjuk balansering? Om Venezuelas ambitioner att minska amerikanskt inflytande
This thesis deals with the concept of soft balancing, traditionally defined as the diplomatic means of restraining a dominant state's ability to exercise its military power. As the dominant power in today's unipolar system, the United States, and other states? behaviour towards it, is the focus of analysis. The aim of this thesis is to explore the possibilities of developing the concept of soft balancing so as to include strategies to restrain also the political and economic capabilities of a dominant power. The thesis also considers the possibilities of soft balancing that small states ? to a large extent overlooked in existing theories on the subject - can possess.As a state with policies that aim to reduce the U.S.
Uppgradering förarstol SEP: på uppdrag av BAE Systems
Hägglunds AB
En prototyp till en förarstol för det militära fordonet SEP har tagits fram av tidigare anställda på BAE Systems Hägglunds AB i Örnsköldsvik. Stolen måste uppfylla en omfattande mängd krav då den är tänkt att användas i ett stridsfordon, och av personer av varierande storlek. Den nuvarande prototypen för stolen anses dock vara för dyr och det har dessutom framkommit en del klagomål på konstruktionen. Stolen måste därför göras om så den blir både billigare och bättre. Genom att ta del av tidigare genomförda tester på BAE Systems, samt genom att göra nya tester upptäcktes det dels vad som var dåligt och därmed behövde göras om, och dels vad som var bra och kunde tänkas behållas.
Veckorevyn.com: En studie utifrån maktrelationer i bloggens värld
Abstract
Title: Veckorevyn.com. A study from power relations in the world of blogs
Author: Klara Sigfridsson
Department for Media and Cultural Studies, Malmö Högskola
Tutor: Kristoffer Gansing
This is a report that aims to research upon Fairclough´s Critical discourse analysis to emphasise the power relationship between professional bloggers and former amateur bloggers at the fashion-entertainment web page Veckorevyn.com. Professional bloggers as they appear in the research object and their power within the Media seem to be a subject that is very relevant these days. This paper will look at different factors that make professional bloggers popular and as an example on their responsibility as a role model. However, amateur bloggers do have an importance in this discussion as they are more and more competing with the professionals.
Marknadsföring av akademiska bibliotek - en jämförande studie mellan Sverige och England
This thesis conducts a comparative study between two academiclibraries, one Swedish and one English, in order to analyse ifdifferent funding systems influence the marketing of theirservices. The theoretic foundation is built on relationshipmarketing, which emphasises the importance of creating andmaintaining relationships. A qualitative approach has been usedthrough the use of case studies, with semi-structured interviewsbeing held with library staff and managers in both countries. Inaddition to these interviews strategic plans have also beenanalysed. The result from the study shows that whilst there aresome differences between the two university libraries there arealso similarities, which indicates that it is not clear if differentfunding systems have an impact on the marketing of the services..
En jämförelse av Sveriges och Storbritanniens producentansvar för förpackningar :
The purpose of the thesis is to compare Sweden's and Great Britain's total costs for their systems regulating producer responsibility for waste packages. Producer resonsibility is a strategy implying that producers are responsible for their waste also after its use. Sweden and Great Britain introduced different systems systems after an EU directive was adopted in 1994 (94/62/EC), and they have resulted in entirely different recycling levels in the two countries.
In the Swedish system, responsibility has been delegated to the industry who are responsible for reaching the determined goals. The economic instrument used is a fee, set and managed by the industry. The British system is more centrilised, and the economic instrument used to finance recycling of waste is a system based on transferable permits.
The thesis compares the four different alternatives: delegated and centralised methods, and fees and transferable permits analytically.
Vindkraft och elbilar på Öland år 2020 : Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?
The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed.The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.
Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet
There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes.
District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption
Research), which has focused on climate adaption in the Nordic countries.
