The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

The purpose of this report is to evaluate different methods for identifying states in robot models. Both linear and non-linear filters exist among these methods and are compared to each other. Advantages, disadvantages and problems that can occur during tuning and running are presented. Additional measurements from accelerometers are added and their use with above mentioned methods for state estimation is evaluated. The evaluation of methods in this report is mainly based on simulations in Matlab, even though some experiments have been performed on laboratory equipment.The conclusion indicates that simple non-linear models with few states can be more accurately estimated with a Kalman filter than with an extended Kalman filter, as long as only linear measurements are used.

This thesis has been written with our society?s current energy-situation in mind.Although it only deals with one particular block of buildings, the solutions and suggestions presented herein are quite applicable on other objects of the same type.This thesis is intended to be used as a guideline for energy-preserving projects in general, with an eye to buildings erected during the Swedish ?million-programme? in the sixties and seventies.The paper starts with the acquiring of all necessary blueprints and technical specifications. It then moves on to a thorough description of the buildings in question, and their heating- and ventilation-systems.Followed by this the reader is guided through the successive stages of energy-perseverance measures that are available, and possible. Reasoning around the economic factors concerning all measures is also held.The paper ends with conclusion, and a discussion concerning the delicate issue of the higher return-temperatures possibly reaching the district-heating plant..

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

This thesis is concerned with investigating the Roma, a group that is left out in most of the territory bound theories. The theoretical purposes are to develop theories that increase the understanding for the Roma as a diasporic nation without state and the advocacy networks they are organised in. The main empirical purpose has been to study two organisations as cases and how they position themselves against the European Union concerning identity politics. The two organisations are European Roma Rights Centre (ERRC) and Dzeno. They are a part of the same network that works on different levels with the rights of Roma.

Energy consumption is at present a major political issue, and numerous projects that comprise many nations are currently in process to increase energy efficiency and bring down energy dependency. As a member state of the EU, Sweden now faces the challenge of implementing substantial energy-saving measures until the year 2016. One of these measures is the project ?Green Islands? financed by the EU that intend on creating sustainable islands in areas around the Baltic Sea. The Archipelago Foundation leads the project that concerns the Stockholm archipelago, where focus has been placed upon decreasing energy usage in businesses and services on Utö among other islands.

The report contains three parts. The first part is a summary and overall presentation of thermalcracks and preventing measures against such cracks. This is a theoretical part where theinterested designer can get acquainted with various alternatives, be guided to more detailedliterature, and receive some practical information regarding the design of the respectivemeasures.The second part deals with calculation of the risk for thermal cracks and design of water coolingas a limiting measure. Two complementary methods are reviewed for efficient calculation:?the handbook method CraX1(by Lulea University of Technology) is used for quickverification?finite differential analysis in the calculationtool ConTeSt Pro for more precise projectingHere is also presented a development of existing standards through design of the cooling systemby means of the Bernoulli equation.

The 1st of January this year the state owned Swedish Luftfartsverket changed their name into the shorter name LFV. The shorter LFV is a more modern version in terms of that the name is a proof of that the classic organisation of the state, Luftfartsverket, with this stepbreaks through boarders and finds new ways. Plans have existed before but since 2005 when Luftfartsverket lost its assignments from the government and become a state owned business corporation, the plans have intensified. Now, also for all the employees, it isgetting obvious that something is going on in the organisation.The purpose of this paper is to see how this newly made change of name and logotype have been recieved and how it has effect the strategic choosen respondents within the organisation LFV. These choosen respondents have thorough knowledge of the organisation of LFV.

The cardiovascular system is one of the three major body systems. When an animal in a critical state arrives at the animal hospital, it is important to know the normal parameters in order to assess the patient?s cardiovascular status. Triage is a process where you considerate the patient?s condition instead of check in time, or other criteria.

Phosphorus is essential to all plants and is taken up from the soil as the ion H2PO4 - (and to some extent HPO42-). Plant availability depends on, among other factors, the soil pH. In order to provide for plant available phosphorus, it is applied as mineral fertilizers and farmyard manure. However, that causes phosphorus leaching from arable land to surrounding surface waters and lakes and contributes to the eutrofication. There are three types of soils in Sweden that are at higher risk of contributing to phosphorus leakage.

The time we live in now is significant for its many ways of spreading information- it is indeed the era of communication. The Internet is the main reason for this evolution, where you can reach out to any corner in the world in less then a second. Information is flowing over us and we get more and more used to being in a constant accessible state. The individual might spread his own word as he wishes. From a democratic point of view this should give a great opening for everyone into the public spheer.

2013. The brave new time.We constantly look forward in time. There is a need today to constantly renew, replace and update almost everything in our lives. Although often stressful, these continual changes and upgrades can open up new possibilities and even be seen as enjoyable and stimulating.Values, opinions, and everything we create, is based on an experience of the past and predictions of what the future might be. I want to take advantage of these thoughts and find out how they relate to our exchangeable culture.

The purpose of this thesis is to discuss education as a state tool in Sweden during the 17th and 18th century. The idea is to contrast the pragmatics of the Swedish education system with the theories of Rousseau and Comenius. The thesis is marked by the thought that theory and application diverse because of the subversive infusion in the ideas of the theoretic.The results shows that it is ultimately a question of public education and its potential. The state recognises the potential of public education but also its dangers and therefore becomes very active in forming not only the education system as a hole but also its pedagogic.

The purpose of this thesis is to explain why states obtain nuclear weapons and the role variousactors and interests play in the making of states´ nuclear policies. The main questions are asfollows: (1) What big theories exist concerning states obtaining nuclear weapon and nucleararmament in International Relations and what relevance do they have of the post cold-war period?,(2) What is the meaning of the perspective of the Military-Industrial Complex (MIC)?, and (3)Arethere empirical studies which supports the existence of a MIC in the United States?The focus lies on actors and driving forces that are internal to states and it is also important toinvestigate if the theories have relevance for the post 9/11-era. The study uses the method ofqualitative literature-study with some quantitative segments. It is claimed that states might beinterested in justifying their behaviour in a morally appealing way and that real reasons may behidden.

In today?s society a large focus is put on energy systems and how our energy systems are built up. In order to make sure that we in the future still can enjoy the living standards that we are used to today, Sweden and EU have made a number of decisions on making our energy system more energy efficient and consequently reduce the usage of energy resources. By 2020 the European Union should have reduced its energy consumption by 20 % compared to 1990?s level, and by 2050, 50%.
