3095 Uppsatser om Democrazy and Division of Power - Sida 33 av 207

Storleksoptimering av en etanolfabrik för integrering med ENA Energis kraftvärmeverk. : Baserat på en regional energibalans mellan tillgång på etanolbränsle i Enköping kommun och producerad etanol med hjälp av tillgänglig ånga från ENA kraftvärmeverk.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

Interaktivitet och deltagande : - en kvalitativ studie kring skapandet av machinima med World of Warcraft -

AbstractTitle: Interactivity and participation - a qualitative study about the making of machinima withWorld of Warcraft (Interaktivitet och och deltagande ? en kvalitativ studie kring skapandet avmachinima med World of Warcraft)Number of pages: 68 total, 50 without appendixAuthor: Peter BrandbergTutor: Else NygrenPeriod: Autumn 2006Course: Media and Communication Studies CUniversity: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The aim of this study is to take a closer look at the phenomenon machinima by analysing a number of specific movies from the site worldcraftmovies.com. This analyse is focusing on how the content of these movies relate to the wider game culture of the MMORPG World of Warcraft, what specific elements in the movies is referring to and if there is differences or similarities between different genres (or categories).Material/Method: The method used in analysing the movies is a combined method inspired by hermeneutic, semiotics and discourse analysis.Main results: Instead of answers this study raises many questions about the diverse content of the movies. A general division can be seen between movies focusing on the games rules and movies that are trying to present a fictive world. But the study also shows how there are many movies moving between these two points.

Laget före jaget : En kvalitativ studie i hur innebandytränare arbetar för att få sina lag att prestera som lag

Denna rapport beskriver det praktiska arbetet för att få innebandy (herr) lag inom division 3 att samarbeta som ett lag. Frågeställningarna som låg till grund för rapporten var vilka metoder och på vilket sätt innebandytränare arbetar för att få ett lag att prestera som ett lag samt hur väl detta överrensstämmer med vad som finns skrivet i litteratur kring ämnet. Syftet var att skapa en förståelse för detta. För att genomföra studien användes en kvalitativ metod och det gjordes telefonintervjuer med fyra stycken innebandytränare.Exempel på vad studien mynnade ut i för resultat och slutsatser var bland annat att flera aspekter som belyses som viktiga i teorin i viss mån även tillämpas praktiskt. Dock visade det sig finnas brister och oklarheter ur flera dimensioner och tränarna skulle kunna arbeta på ett mer medvetet, strukturerat och konkretiserat sätt med exempelvis feedback och gruppstärkande övningar för att effektivisera samarbetet och sammanhållningen i laget.

Therefore, the thesis is trying to find distinguishing characteristic traits for football supporters. This work has been carried out through qualitative interviews with individuals who define themselves as football supporters. The interviews were mainly focused on two different types of supporters, official supporters and other supporters.

På olika villkor : En intervjustudie om häktades och kriminalvårdares upplevelser av häktet

Different Perspectives is a study of detainees' and guards' experiences of the remand prison. The result of the study shows that the remand prison brings forth the individuals anxiety, stress and fear. The individual detained in remand prison have a great need for contact with their families, but also with the guards. In the remand prison there is always a great level of control and always some kind of power practised. It is the guards who have the power and the competences to make the individuals detained in remand prison follow the rules and do what they have been told.

Ledarens roll inom privat respektive kommunal handikappsomsorg : En kvalitativ jämförande studie mellan ledare inom privat och kommunal assistansverksamhet

AbstractSince the Act Regarding Support and Service to Certain Functionally Handicapped Persons (LSS) were introduced in 1994, social care and service have increased inSweden(SFS 1993:387). The implementation of the act has caused many changes and also progress within the social care system. One main change is the division between public (provided by the municipalities) and private care providers. This division has led to many questions about how leadership is organized within different public and private organizations.The purpose of this study is to investigate differences between leader?s experiences of their role and working conditions within private and public assistance care for disabled.

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.

Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande

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.

Den digitala klyftan ? En studie om e-­?Förvaltning

Den digitala klyftan är inget nytt fenomen utan har diskuterats sen 1970-talet då skillnaden ianvändandet och tillgång av video och telefax avsågs. Idag syftar den digitala klyftan snararetill användningen och tillgången till Internet. Andersson (2003) identifierade sex olikagrupper som hon ansåg ingick i den digitala klyftan. I den här studien används teorin om detoffentliga etoset som utgångspunkt för att kunna analysera den digitala klyftan. Syftet medstudien är att diskutera vad det är för perspektiv som genomsyrar svenska myndighetersverksamhet i e-Förvaltning, men även att bidra till en diskussion som handlar om att urskiljaoch förstå om den digitala klyftan är ett demokratiskt problem.Offentligt etos är ett samlingsnamn som innefattar olika begrepp och dimensioner somgenomsyrar den offentliga verksamheten.

Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige

The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.

Om leken i nödvändigheten

This study aims to examine play as a phenomena from a phenomenological approach. This I do by discussing a dominant approach to play, an perspective which is reproduced in the context of pre-school and in where the play and learning is in single focus. Using alternative perspective on play, mainly by Gadamer and Bakthtins philosophical thoughts about the feast or the carnival, contents differ significantly from educational or developmental psychology perspectives. I open up for an understanding of what play as ontology can be understood as, and thereby enable second readings. I illustrate this thought by an empirical example from a pre-school context which where created alongside with the children in the study.

Transformatordiagnostik genom dissolverad gasanalys

The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.

Drivförstärkare : Bredbandig drivförstärkare med hög verkningsgrad

This report present the design and manufacturing of a wide-band driver amplifier placed in radar module for airborne applications. The major goals for the amplifier were a high efficiency and to deliver a predefined output power. To reach the second goal an additional preamplifier had to be constructed. The amplifiers were constructed in three steps: Design and Layout in the software Microwave Office, Mounting components and Verification. The driver amplifier was decided to be a push pull configuration consisting of two parallel transistors biased in class AB.

Påverkan av skuggor från vindkraftverk

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Luftmakt : en komparativ studie mellan centrala luftmaktsteorier och svensk doktrin för luftoperationer

Att utnyttja flygstridskrafter har sedan tidernas begynnelse varit en effektiv metod att påtvinga motparten sin egen vilja. Sättet man använt flygstridskrafterna på har debatterats under historiens gång. Inom ämnet luftmakt finns det en rad kända och inflytelserika luftmaktsteoretiker som alla har sin idé om hur man bäst utnyttjar flygstridskrafter. Hur ser vår svenska doktrin ut gällande teorier kring luftmakt? Vilka luftmaktsteorier genomsyrar grundtanken bakom hur vi idag vägleder våra luftoperationer? Syftet med uppsatsen är att undersöka vilka generella och centrala luftmaktsteorier som återfinns i den svenska doktrinen.
