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.
Centraliserad personalavdelning- bästa verktyget för chefsstöd? : En kvalitativ studie om arbetssituationen relaterat till chefsstödet från personalavdelningen vid Uppsala kommun.
Changes in the workplace have led to new ways of organizing and structuring organizations. Organizations? desire to increase competitiveness, efficiency and flexibility has resulted in new conditions in the field of human resources. The new conditions have also created new roles and changing responsibilities for those working within human resources.The purpose of this study was to investigate how the implementation of Ulrich's model for HR transformation can impact on the human resource departments managerial support to first-line managers in the municipality of Uppsala. Today the municipality of Uppsala organizes its human resources based on the Ulrich's model, which divides the work into the units service center, the expert unit and business partners.
Modellering och reglering av mjölkningsrobot
In this master thesis a robot arm belonging to an automatic milking machine from DeLaval is investigated. The robot arm is controlled by a pneumatic cylinder and a valve. The goal of the master thesis is to investigate instability problems and to find out if it is possible to solve them by using gain scheduling. Gain scheduling is a type of controller where the parameters of the controller are changed during operation, for example depending on the working point. First a nonlinear mathematical model of the system was made.
Han och hon möter vi och dom ? den universella välfärdspolitikens akilleshäl : En studie av kön och ras i svensk förvaltning
Gender politics in Sweden is considered unique because gender policies (jämställdhet) are integrated into national politics and politicised both in the public and the private sphere. The Swedish case is therefore considered a role model by many feminist scholars.This view has been criticised by both post modern feminists and public administration scholars. Critics imply that the increased immigration and more heterogeneous population have led to a new challenge for state institutions. The Swedish model, with its universal welfare solutions, lacks the ability to recognise differences within groups. Universal solutions that treat everyone the same is no longer the most just way to treat people.The growing use of goal orientation in Swedish public administration has increased the civil servants discretion in the implementation process, and thereby the space for differentiated treatment.
3D-byggnadsmodeller utifrån takkonstruktioner : Lagring, hantering och bearbetning
A growing number of cities and municipalities in Sweden begin to work with city models in 3D. For the most part the models are used for visualizations of ongoing planning processes, but also for the analysis of noise, shadow studies and environmental disaster simulations.Gothenburg continues to develop the use of 3D maps in municipal operations and is demanding a way to create building elements (walls), which generates in 3D buildings, from roof constructions that are mapped from the primary map. A method has been investigated in the present study. The results are then presented as a 3D model of buildings, along with a terrain map that will facilitate the localization of the area. The created 3D buildings are then compared with roof-data from the primary map to see how well they harmonize with each other.

Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik
This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.
Metallersättning inom byggbranschen
In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.
Styr uppfattningen om dig själv : En studie i hur chefredaktörer för modemagasin arbetar med sina personliga varumäkesidentiteter
The theory chapter is based on a model about brand identity, ?Brand Identity Prism? (Kapferer, 2008, s.183). This model contains six elements which we have supplemented with theories about personal branding. This because the focus and theory on a person's brand identity is almost non-existent. The purpose of the study is therefore to examine how editors at fashion magazines are working with their brand identity in the personal brand and thereby create an understanding of the identity function.
Numerisk modell för global transport av spårämnen i atmosfären
The aim of this project was to develop a numerical model simulating the global transport of air pollution. The model currently used by SMHI, the Swedish Meteorological and Hydrological Institute, was intended to perform such simulations at regional scales. However, the usage of a grid based on longitudes and latitudes makes this model work poorly in global simulations. The problem with this grid is that the nodes are concentrated near the North and South Poles. Due to this characteristic, the Courant, Friedrich and Lewy-condition for numerical stability puts a sharp bound on the timestep length.
Underlag för bedömning av energibrunnar inom vattenskyddsområde
Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.
Prediktering av fartygsbränsleförbrukning i varierandesjötillstånd
During the 2000s, the ship owners have become more and more concerned thattheir ships save fuel. Several projects have been undertaken to exploit the resourcesavailable on board today?s vessels to reduce fuel consumption. As a stepin this the Swedish Meteorological and Hydrological Institute (SMHI) today offera Weather Routing service to ships. By planning your route more effectivelymuch fuel can be saved.This thesis has been about developing a fuel prediction program (FPP) forhow much fuel a ship consumes in different sea conditions.
Development of Liquid Cooling for PCs
In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
Corpus Technologica : En religionshistorisk analys av Robert Anton Wilsons version av The Eight Circuit Model of Consciousness i ljuset av den västerländska esoterismen
This is a thesis about The Eight Circuit Model, a modern mind map developed for the purpose of illumination and enlighenment by Dr. Timothy Leary in the 1970s. Later, authors such as Robert Anton Wilson and Antero Alli elaborated upon the idea to make it more wholesome and compatible with other ideas expressing the same basic principle. In short, it is an intellectual abstraction of the evolution of consciousness through a series of eight stages, which Leary called Circuits. By looking at the brain as an evolving bio-computer, with thoughts working as software, upgrading itself through neurological imprints, Learys created a Hero's Journey for the modern age.The thesis tries to analyze this idea, as it is presented in Robert Anton Wilsons Prometheus Rising, through the lens of the discourse category ?Western Esoterism.? A hard-to-define subject but described as ?the dialectic of the hidden and the revealed in the field of religion.?.
Modellerade och uppmätta kväveflöden i energiskog som bevattnas med avloppsvatten
The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.
