The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Denna studie har som syfte att underso?ka om det finns en typ av system vars egenskaper liknar ba?de traditionella system och e-infrastrukturer utan att tillho?ra na?gon av dessa typer samt hur en designmodell skulle se ut fo?r denna typ av system. Detta system kallar vi gra?nsfallssystem.Fo?r att underso?ka om denna finns har traditionella system och e-infrastrukturer samt hur man utvecklar dessa typer av system analyserats. Detta fo?r att se ifall det existerar na?gon form av system som har egenskaper fra?n ba?da dessa ytterligheter och om det existerar sa?dana system hur man pa? ba?sta sa?tt ska utveckla dem.

 Dissertation in political science, C-level by Niklas Andersson, Spring Semester 2009. Tutor: Arne Larsson?The Treaty of Lisbon ? The Defence against Globalization??In the modern world globalization have undermined the nation-state and left it without the right measurements to adequately deal with the social and economic unrest that follows in its way. The states, built on contract theories, have an obligation to protect its citizens from the state of nature which seems to have failed as globalization has changed the rules.The purpose of this dissertation is to examine the contract theories of Thomas Hobbes, John Locke, Jean-Jacques Rousseau and John Rawls to identify the elements of a state and create a modern and ideal contract theory. The treaty shall then be used on the Treaty of Lisbon as it can be seen as a contract between the European states to create an entity in the shape of the European Union with the power to defend Europe from the unrest created by globalization.My question for this was as follows:Is the new treaty for the European Union acceptable as a new social contract according to the social contract theories?During my research the following criteria?s for a social contract was found:1.

Since Muhammad Yunus, founder of the microloansorganization Grameen Bank, was awardedthe Nobel Peace Prize in 2006, the microloansorganization has received much attention. Thewoman has come to play a central role in the microloansorganizations. Her access to capital isis considered to improve her socioeconomic status. The overall aim of the paper is to examinehow access to microcredit considered leading to empowerment of women. To get an idea ofwhat a microloansorganization is the Grameen Bank is used as an example.

The gambling industry goes from a national matter towards an international market. Since more and more members of EU does liberalise the gambling reforms and introduces a license system more participants will get an EU license for online gambling. With an EU license it is difficult for members of the EU to refuse a company to offer a gambling supply on the Internet if they don?t have an open license system. This paper tries to acknowledge the problem regarding the monopoly Sweden has today and calculate the effect if Sweden would move to a license system regarding online gambling by doing a cost benefit analysis.

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

Den här uppsatsen mål är att undersöka om ekonomiska sanktioner är ett försvarbart utrikespolitiskt medel. Sanktioners effektivitet utreds genom en kvantitativ studie av sanktioner utfärdade av FN och en kvalitativ studie av fallet Sydafrika. Uppsatsen konstaterar att ekonomiska sanktioner är ineffektiva och kostsamma och går därefter över till att diskutera dem i normativ analys och försöker sedan utreda vilka fördelar som kan identifieras och erbjuder konstruktiv kritik av ekonomiska sanktioner. En positiv faktor som identifieras är den psykologiska påverkan som sanktioner har på en inhemsk motståndrörelse för att visa omvärldens stöd. Slutligen konstateras att smarta sanktioner och vapenembargon kan vara komplimenterande åtgärder, men inte uppfyller sina mål utan hård bevakning..

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

This report documents the development of a software system for automaticscheduling called Hazel. This system is comprised of a server where an automaticscheduler has been implemented, as well as a web and mobile applicationthat allows users to interact with the system. The scheduler hasbeen developed with the functional programming language Haskell and usesa SAT-solver.Manual scheduling has long been the bane of managers everywhere, asmatching the needs of the employer with those of the employee is often adifficult and time-consuming task. There already exists several automaticschedulers that attempt to solve this problem. The issue with said schedulersis that thay tend to be expensive, or developed to only fulfill the needsof a particular organisation.

Electrolux Laundry Systems is the world leader in manufacturing professional laundry equipment.The machines are used in the hotel sector, elderly care, in multifamily houses, laundry bars, and incommercial and institutional laundries.If there is oil or grease left in the clothes after washing may the heat from the dryer cause a chemicalreaction. This reaction may, under certain circumstances cause a fire inside the drum. Competitors toElectrolux has developed its own systems that extinguishes fire inside a tumble dryer and customershave expressed desire to purchase a fire-extinguishing system. Therefore, the project team receivedthe task by Electrolux to develop a fire-extinguishing system that extinguishes a fire in a tumbledryer.The purpose of the project has been to develop a system that both detects and responds to fire in anindustrial tumble dryer to meet the competitors and to satisfy customers' requirements.The goal was to develop a fire-extinguishing system for Electrolux Laundry Systems and develop afully functioning prototype.The project began with information searches on a variety of methods to both detect and extinguish afire. Subsequently, a number of different methods were used to develop a final solution and make aprototype.The result of the project is a fire-extinguishing system that extinguishes a fire inside a dryer.

This thesis aims at investigating the conflict development of Swedish foreign policy debates during 1989-2000. It is rather assumed that the Swedish foreign policy debates have been highly characterized by a large consensus. Despite that, there have been certain occurrences where the political parties have flushed into party struggle and shown disagreements over the party frontiers. This has raised questions about the range of conflict and consensus in such debates where I have studied the political parties' backchats. I have studied situations where the political parties replicate each other in order to investigate the range of consensus and controversy that exists within different foreign policy areas.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Citizens? freedom of choice has been a subject of debate in Sweden for over 30 years. This study focuses on decision making processes among patients within the Swedish healthcare system. The main conclusions are that in contrast to how patients? freedom of choice is described within governmental bills and governmental inquires and reports, patients are not following the steps included in the rational model of decision making.

The aftermath of colonization, culture diversity and the recognition of the ownidentity - living in a country which has the role of a former colonizer has got consequences in the multicultural French society. These consequences can be seen studying the politics, the education and the history of that country. In this bachelorthesis I discuss the aftermath of French colonization with a focus on how the French cultural identity can be explained in defining colonialism in French lawmaking. The aim is to understand the definition of the own cultural identity from a postcolonial perspective and what meaning the multicultural society has for this definition. This is an issue which can be seen in politics as well as ineveryday life, and to make an understanding of it, I study how French politicians are representing their country's role as a former colonizer in a postcolonial era.

This report describes a system for verification of fingerprints against a previous created template. It describes how and why a fingerprint image must be processed before it can be used to either identify or verify a person. The method is based on special features of a fingerprint, called minutiae points. The whole process from image to matching is described, every step in the process with image enhancement, binarization, thinning and how to find the minutiae points. Also what false minutiae points are, how they arise, why they deteriorate the result, and how to handle them, is discussed.
