A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..

ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

My essay is concerned with intercultural leadership and practical knowledge. The essay is about ethical dilemmas and the diversity of issues we face constantly at the preschool. In my story I examine the different views of knowledge and the opportunities to lead people in an intercultural way, and how they relate to each other. I start by looking at the ethical ideas that form the basis for our actions and our view of knowledge. Then, I examine how the practical wisdom guides the ethical dilemmas that arise at the preschool.

Sweden  has  been  characterized  as  one  of  the world?s most  secular  countries, even though  it is  becoming  increasingly more multicultural.  This,  combined  with  the fact that pupils do  not  feel  they  have  enough  time  in  school  for  Religious  Education and that the requirements are increasing made me interested in how they talk about religion in upper secondary school. The aim of this study is to see if there are any differences between how pupils in vocational programs and academic programs are talking about religion and Religious Education. The main questions that were raised revolved around 1)  how  pupils  talk  about  what  religion  is,  2)  how  they  talk  about  religion  in  the Swedish  society  and  3) how  they  talk  about  Religious  Education  in  upper  secondary school. The questions were also about what similarities and differences I could find in the way they talked about these subjects.

This bachelor?s thesis is a study that examines cactus groups in Sweden from a heritage conservation perspective. Through interviews and an analysis of both historical and modern literature, the research explores why cactus groups became popular and what is required to preserve those still in existence today. A recurring challenge has been the lack of comprehensive source material, leaving some questions open for further research. The study focuses on four cities?Norrk?ping, Skellefte?, Varberg, and V?xj??that have maintained their cactus groups for nearly a century.

In the current situation is the straight tube cutter, that provides Luvata?s line of large recoolers with copper tubes, manually operated. To prevent damages and facilitate mounting the tubes must be properly arranged when they leave the machine. This report aims to investigate and present an automated solution where the operator does not need to participate in the process. A number of theories have been drawn up and tests have been done.

This thesis examines how a jury on an artistic education adopts next year's students to a BA program at an art school. My intention is to explore how we established artists who are involved in education as professors, teachers (or students) in art education affects who will be released to the exclusive educational path as an art school represents our work in the admissions jury. My ambition is to create an awareness of what it might mean for the reproduction of the artist..

The aim of this thesis is to analyze the media discussions of the rape in Bjästa 2009 and to reveal how stereotypical illusions of ethnicity, religion and gender affect how media understands and defines violence. The rape in Bjästa occurred in a ?Swedish context? but has been defined as honor related in other arenas outside media. This discussion occurred because the whole village turned against the woman that was raped and supported the perpetrator? a phenomena that speaks against the idea of an equal society and a behavior that is usually understood as honor related and something that the ?others? do.

Syfte: Syftet var att undersöka vad kommunikationsbrister kan bero på och hur en organisation kan gå tillväga för att lösa problem som uppstår på grund av dem. Med detta som grund har studien utformat rekommendationer för hur förvärvsorganisationer kan arbeta med den interna kommunikationen och på så sätt överkomma och förebygga brister i kommunikationen.Metod: En fallstudie utifrån en deduktiv forskningsprocess användes genom att ställa upp påståenden utifrån teorin som prövades på empirin. Datainsamlingen skedde genom kvalitativa intervjuer och en kvantitativ enkät.Slutsats: Brister som uppstår i kommunikationen har en verkan på hela organisationens finansiella och prestationsmässiga resultat. Genom att lägga beslag på kommunikationen kan en förvärvsorganisation bli mer framgångsrik..

Conclusions: A myriad of interpretations are possible when studying and discussing a particular organizational culture. As culture can not be removed from its context, we illuminate the effects that the internationalization process has with regards to unifying the organizational culture in our particular setting studied. Maintaining however, that a reflexive look at this culture shows no single interpretation as being sufficient, we try to expose its richness and ambiguities through a three perspective approach..

In our modern society, time is important. Technology is used in countless ways to faster get us from one point to another. The purpose of this report is to inquire whether there is a way to implement an option for personnel at Swedish hospitals to claim priority on an elevator call, and to do this in an efficient way. An ordinary elevator system has been simulated with an implementation of textit{Nearest Car algorithm}, an algorithm which calculates the most suitable elevator car to serve a specific call considering the distance between the call floor and the car and the direction. Along with this algorithm, different ways to handle priority calls has been implemented to see how they affect the mean transport time for both passengers with priority and regular passengers in the elevator.

Denna uppsats rör sig inom fältet kritiska kulturarvsstudier och fokuserar på svensk utförselreglering av kulturhistoriska föremål genom tiderna. Utgångspunkten ligger i 2014 års omformulering av kulturmiljölagens portalparagraf, vilken numera inkluderar mångfaldsmål. Kulturmiljölagens utförselreglering (reglerad i 5:e kapitlet), som inte uppdaterades samtidigt, är tänkt att läsas mot bakgrund av de inledande bestämmelserna. Eftersom den sedan tidigare uppfattats vila på ålderdomliga nationalistiska värdegrunder, uppstod frågan ifall det fanns en diskrepans i förhållande till de nya målen.För att hitta svar söker sig uppsatsen tillbaka till utförselregleringens formativa moment samt förändring från 1920-talet och framåt och sätter detta i relation till nuvarande kulturpolitiska mål och kulturvård i dagens samhälle. Motiv till utförselreglering men också vilka föremålstyper som skyddats genom tiderna har studerats, analyserats och jämförts kvalitativt.

The purpose of this report is to compile and examine the cost of renovation of moisture-damaged bathrooms, to derive a target price. The target price can then be used by insurance companies to estimate the ultimate cost of future bathroom renovations.       The method is based on the compilation and comparison of the cost of repairs of previous water damage in bathrooms. The calculations compiled based on repair estimates for different insurance losses from one of the leading insurance companies in Sweden.       The result shows the average price per square meter of floor area for different sizes of bathrooms. The average price is the basis for the estimate of future renovation costs of bathrooms. The results further show that the bathroom finishes, area and the distance between the entrepreneur and the location of the renovation have great impact on the final repairing cost.
