Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ
Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by
Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer
(system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in
terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.
Skötsamhetens makt - Den moraliska sensibilitetens struktur och maktgörandets beståndsdelar: Hur kan dygderna fördjupa förståelsen kring empowermentprocesser?
This essay shows how the concept of virtue can deepen our understanding considering processes of empowerment. A virtue is understood as a trait of character, manifested in habitual action, that it is good for person a to have. Virtues are interpreted as socially constructed. Empowerment is presented as a process toward self-confidence and self-determination where recourses and freedom propels the development toward power for the individual, the household and the community. Why does the concept of virtue deepen our understanding? It is argued that our theoretical perceptive of empowerment needs to better encompass values, norms and practise.
Mötet, ett dilemma eller en möjlighet? : - En kvalitativ studie av myndighetspersoners beskrivningar av individer med ett socialt funktionshinder.
This is a study with a qualitative approach and a social psychological perspective. Our purpose is to describe and analyze authority officials descriptions of individuals with a social disability and their perception of how the interaction in the encounter with its implementation. We are interested in how they experience their power as authority representatives. The following issues are highlighted.? How do people in authority describe individuals with a social disability?? What is the authority officials view on the interaction in meetings with individuals with a social disability??

Energy efficient storage of biomass at Vattenfall heat and power plants
Storage of biomass is often associated with problems such as heat development, dry
matter losses and reduction of fuel quality. The rise in temperature can potentially
cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles
can cause health problems in the surrounding. The dry matter losses and reduction of
fuel quality can have economical effects. The aim of this thesis project is to develop
guidelines on how to store large amount of biomass at Vattenfalls heat and power
plants in an optimal way.
GPGPU : Bildbehandling på grafikkort
GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..
Rätten att benämna : Maktutövning i Amalie Skrams psykiatriromaner
Amalie Skram (1846-1905) was born in Norway but lived in Denmark. She published several books about gender relations and built up a reputation as a naturalistic writer. In 1894, a nervous breakdown made her seek help from the famous psychiatrist Knud Pontoppidan. He sent her to an asylum, but she returned home after spending two months in psychiatric care. In 1895, Skram published two novels about the painter Else Kant, based on her own experiences but not written as autobiographies.
EU:s inflytande vid gränskonflikter: Fallet Cypern- En fallstudie av EU:s maktutövning i Cypernkonflikten
This study discusses the European Union´s influence regarding the Cyprus Conflict since 1998, when the EU began the official membership negotioations with Cyprus. The first aim of the study is to investigate in what way the EU has tried to practice influence concerning the Greek- and Turk Cypriots, but also Turkey, since Turkey is seen as a relevant party in the conflict. The second aim of the study is to examine what effects the EU´s influence has led to for the parties involved. The theoretical approach in the study is the theory Normative power, the theory stresses that Europe and the EU practices non-military power, and is able to do so because of the fact that the EU is based on internationally acknowledged desirable norms, as democracy and human rights and liberties. The result of the study shows that the EU has been an active participant concerning the Cyprus Conflict by successfully influencing the Greek- Cypriot government and Turkey e.g.
Kampen om Könskriget : - en diskursteoretisk analys av meningsskapande kring Dokument Inifråns granskning av extremfeminismen
AbstractTitle: The struggle of ?The war of the sexes?- A discoursetheoretical analysis of Dokument Inifrån?s review of extreme feminism (Kampen om Könskriget ? En diskursteoretisk analys av meningsskapande kring Dokument Inifråns granskning av extremfeminismen)Number of pages: 40Author: Anna OsterlingTutor: Amelie HössjerCourse: Media and Communication Studies DPeriod: March ? May 2006University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: To analyse the debate in Dagens Nyheter from May 2005-June 2005 concerning the documentaries ?The war of the sexes? and to use discourse theory to reflect upon how the texts create different thruths and discources. A second purpose is to analyse how the texts create identities and groups, mainly concerning feminism. A third purpose is to relate the creation of meaning to structures of power and genderrelations.Material/Method: The material consists of 57 texts from Dagens Nyheter published during the chosen period, all relating to the documentaries. The method is textual analysis with a discoursetheoretical persective and analysis of societal structures and power using theories from Foucault, Conell and Säljö.Main results: There are several discourses struggling to create mening around ?The war of the sexes? of which some are greatly antagonistic towards each other.
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.
Internet of Things & Kommunikationsprotokoll
Genom att studera olika kommunikationsprotokoll kunna svara på vad det är som gör att ett visst protokoll är bäst anpassat för att användas mellan mobila enheter och IoT-enheter.I arbetet användes en kvalitativ litteraturstudie för att ge en grundlig teoretisk bakgrund samt en experimentell studie där ett par teorier undersökts ifall de stämmer med resultaten ifrån verkligheten. De fem faktorerna kompatibilitet, batteritid, frekvens, räckvidd och tillförlitlighet undersöktes hos kommunikationsprotokollen Bluetooth Low Energy (BLE), Närfältskommunikation (NFC) och Wi-Fi. Dessa tre valdes eftersom de stöds av nyare mobila plattformar idag. Kommunikations-protokollen analyserades sedan gentemot olika användningsområden inom IoT, eftersom påståendet vad som är bäst anpassat beror på vad situationen kräver för egenskaper.En systemutvecklare som ska välja kommunikationsprotokoll till en IoT-tillämpning och läser denna rapport bör själv jämföra de olika protokollen mot varandra inom de fem faktorerna för att kunna avgöra vilket protokoll som passar bäst inom dennes situation. I arbetet utfördes endast experimentella studier på BLE på grund av begränsningar inom utrustningen.
Effekten av 6 veckor unilaterala knäböj, med eller utan isokinetiskt motstånd, på power och sprinttid på is hos manliga ishockeyspelare
För att kunna prestera bra under fysiskt krävande ishockeymatcher krävs det att spelarna harhög maximal benstyrka och en hög explosiv förmåga. Bilaterala knäböj är en erkänd och välspridd övning för att förbättra power och muskelstyrka i benen. Unilaterala knäböj är än mersportspecifika för ishockeyn. Vid en isokinetisk rörelse är hastigheten förutbestämd ochdärmed konstant medan kraften kan förändras under rörelsen. De flesta isokinetiska systemhar varit designade för unilaterala isolerade övningar, men gällande isokinetiskaflerledsövningar så som knäböj tycks det inte finnas någon forskning om i nuläget.Studiens syfte var att undersöka effekten av sex veckors unilateral styrketräning (knäböj),antingen genom traditionell eller genom isokinetisk träning, på power i unilaterala ochbilaterala jump squats och 17.3 m sprinttid på is hos manliga juniorishockeyspelare.20 manliga ishockeyspelare på elitnivå, 18-19 år gamla, delades slumpmässigt in i två olikaträningsgrupper.
Power and exercise public authority.
I denna studie har jag försökt få en ökad kunskap om hur biståndshandläggare upplever samt hur dessa hanterar makten i sina arbeten som myndighetsutövare. För att kunna uppnå mitt syfte har jag intervjuat fyra biståndshandläggare inom samma kommun som alla arbetar mot lagen om stöd och service till vissa funktionshindrade (LSS). Intervjumaterialet har jag analyserat utifrån Michel Foucaults relationella maktbegrepp. Det visade sig att informanterna inte reflekterade över makten utan fokuserar istället på den enskilde brukarens behov av diverse hjälpinsatser från kommunen..
Olika kön - olika bedömningar? : En kvalitativ studie baserad på socialarbetares bedömningar kring ett enskilt fall
This qualitative study aims to highlight if there are any gender difference in social workers reasoning about a particular case. To achieve a deeper understanding we had to explain and understand our respondent?s answers, primarily from a gender perspective, but also from a power perspective. Our questions were: how does social worker reasoning about a particular case? How can we understand the social workers answer from a gender- and power perspective? The method consisted of a construct case and of semi-structured interviews.
Dämpning av ljud i Shift-by-Wire växelväljare : Noise damping in a Shift-by-Wire gear shifter
Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. Kongsbergs Automotive has developed a new gear shifter platform (Shift-by-Wire) that is sold to Alfa Romeo and used in of their car models. However, the company is not pleased with the components sound quality, therefore the main purpose of this thesis is to develope a number of concepts that is supposed to enhance these NVH-aspects.To get an understanding of the problem an analysis of the causes of the emitted sound has been done parallell to a product decomposition, function decomposition and a Ishikawa-diagram. Together with these methods has a litterature study been performed to get familiar with the physics of an impact and especially the emittment of noise.
Utredning av solenergi för drivning av sorptiv kylprocess för inomhusluften på Stockholmsarenan
Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.
