Framtagning av reläskyddsinställningar för en transformatorstation

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.

Hur formar handledningen mig som psykolog? : En kvalitativ studie av nyutexaminerade psykologers upplevelser av yrkeshandledning.

The aim of this study is to, by individual interviews focusing on specific dimensions of supervision,examine how integratively educated PTP-psychologists experience the interactionin the supervision they receive as a part of their PTP-work and to describe if and how theyexperience that these components of the supervision promote, does not exert a direct influenceon or restrain the preservation and development of an integrative psychotherapeuticapproach and -attitude. The eleven people who are interviewed for this study all belong tothe group of psychologists who graduated from the first group of psychologists with an integrativepsychotherapeutic approach at Örebro university in the year of 2007 and who arenow completing their PTP-work. The interviews were analysed according to a qualitativecontent analysis. The results show that ten out of eleven PTP-psychologists experience thatthe interaction in the supervision is either good or excellent and that this promotes or doesnot exert a direct influence on the integrative approach.Keywords: Supervision, PTP-psychologist, integrative approach..

Utvärdering gällande implementeringen av System Aircraft Management för Täby Air Maintenance AB

Today we live in a world where the demands increase in the aeronautics industry. This creates a situation where no mistakes are allowed about the regulations and for those who are supposed to follow these. Safety comes first, tracking of components, Service Bulletins which are recommendations from the manufactures and Airworthiness Directives which are demands from the authorities, these need to be updated at all time and everything that is done on a aircraft need to be documented.This creates a situation where today maintenance shops need to have full control of all parts of the organization, which creates a need for a working data system.The goal with this exam work is to evaluate the best way to implicate the new bought data system called "System Aircraft Management" on the basis of the needs of Täby Air Maintenance AB. The system are supposed to get started technically and also be implicated to the users of the system. This work will be focused to create a effective working plan to get SAM implicated with no interruption in the daily work.

Urbana utväxter : konsumtionskoncentrat

The shopping mall is a reflection of the city and its habitants, a concentrate of the modern city. I have studied the dialogues of malls and the communication within, how malls are put together and what they communicate. The city is constantly changing. As soon as we try to grasp the city, it slips away. My opinion is that city planners and landscape architects need to widen their views. City planning needs to develop to better fit to the changes of our modern cities.

I sökandet efter framtidens destinationer : Ur researrangörers perspektiv

Background: The fast growing tourism industry increases the need for new destinations to meet the markets demand. Because of this, destination development becomes a part of tourism development and it can therefore be interesting and relevant to study this phenomenon. It requires consciousness about the destination?s conditions and to what extent tourism can be developed. The study of these conditions can be useful as they are fundamental for future tourism development at a destination.Purpose: The purpose of this study is to describe and analyze which conditions and characteristics a place should have to become an attractive destination.Methodology: This study has been executed from a positivistic point of view and a quantitative approach.

Bryggor - En studie av bryggors förekomst i publika bolag och påverkan på träffsäkerhet i analytikerestimat av EPS

Previous studies have shown that there is a relationship between voluntary disclosure and analysts' forecast accuracy. However, there has been no research conducted specifically on bridges. Bridges contain information on how components such as price, volume, foreign exchange rates and acquisitions have impacted the financial performance between two periods. The main purpose of this thesis is to investigate the usage of bridges in quarterly financial information of companies listed on Nasdaq Stockholm. We provide a descriptive mapping of bridges and find that 30 out of 268 companies are presenting bridges as a part of their voluntary disclosures, with large firms being the most frequent users.

Musik och kunskapsskillnader : -En studie om musiklärares upplevelser kring kunskapsskillnader inom musiken

ABSTRACTMusic and differences in knowledge ? a study of music teachers experiences with differences in musical knowledge. The purpose of this paper is to, out of a music teacher?s perspective, see if the differences in music abilities between 7th grade students are at all, or in some ways connected to the previous schools they?ve attended. I will also research in what areas, in the subject of music, students are differing more, as well as less, in their knowledge. The analysis is based on interviews with six 7th grade music teachers working in the Swedish nine-year compulsory school system.

Konstruktion och utvärdering av diplexer

The report descripbs how a diplexer for a hybrid analog/digital filterbank has been constructed and tested. A diplexer divides the frequency band into two different bands that do not who doesn't overlapp each other. The sampling rate for the two ADC:s is 80 Msps, and therefore it is advantage to have zero at 80 MHz. The reason for this is that a proposed class of hybrid filterbanks with very good quality requires a zero at or close the sampling frequency to work well. The diplexer was made in three versions.

?Fotboll är bara en världslig sak, det betyder inget för evigheten? Religionsvetenskapliga perspektiv på fotbollsintresse

This qualitative study examines if an interest in soccer can give the same meaningfulexperiences in a person's life as a religion would. Five soccer fans were interviewedregarding the meanings and impact of soccer in their lives. Two theories in the fields ofsport and religion were used to analyze the data: Antonovsky's sense of coherence (SOC)with its components meaningfulness, manageability and comprehensibility and Heelasand Woodheads "life-as" and "the subjective-life? derived from the concept "thesubjective turn". It was concluded that the interest in soccer affected the respondents?views of life.The respondents? personal identities were strongly associated with groupmembership, meaning that their interest in common with others was perceived to makeeveryday life meaningful and manageable.

Cykeltouren

The number of locals in Stockholm who chooses the bike in front of public transport has increased significantly in recent years. The product purchaser of this project, Joakim Victorin at Sigma AB, has a keen interest in cycling, which resulted in a fairly obvious topic of this project; through a web application Sigma AB wanted to make it possible to handle results from professional as well as amateur competitions in cycling.The purpose of this web application is to simplify reporting and handling of competition for both small and bigger bicycle races. By providing the users of the system a platform independent client, any available device may be used.This thesis has followed the development principles which prevail on the ASP .NET MVC 3 concept. When developing the system the Microsoft Visual Studio 2010 development environment was used. The framework and the pattern of ASP .NET MVC 3 is a prominent part of today?s web development.

Design of automatic measurements systems for characterizing RF-components

Arbetet bygger på att de informationssystem som används idag men som blir allt äldre och därigenom inte klarar de krav som ställs på dem. Detta medför att informationssystemen måste migreras till modernare plattformar, då företagen dels inte klarar sig utan dess nuvarande funktionalitet och dels måste vidareutveckla systemen.Detta arbete tar upp olika sätt som detta kan genomföras på och vilka problem som kan komma att uppstå när detta sker. För att kunna undersöka detta så genomfördes ett antal migrationer. Språken som migrationen kommer att ske mellan är Visual Basic 6 och Visual Basic .net. Migrationerna kommer att ske med hjälp av ett migrationsverktyg, samt ett ramverk som i arbetet skräddarsys för just arbetets typ av migrationer.Det arbetet kommer fram till är att det sker problem vid användande av ett verktyg och även att det inte ger tillräckligt med respons på vad som gått snett under migrationerna..

Design och konstruktion av laborationsutrustning till en kraftelektronikkurs

The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..

RFID:s effekter inom logistik

Modeprodukter har en mycket kort livslängd och modebranschen förändras snabbt. Tiden är därför essentiell och utgör en betydelsefull konkurrensfaktor. Genom att reducera tid i försörjningskedjan kan ett företag vinna marknadsandelar samt höja sin lönsamhet. RFID är en teknik som kan användas för att reducera tid samt förbättra logistiska processer i försörjningskedjor. Trots att denna teknik har börjat spridas, används den generellt inte hos svenska modeföretag.

Passivhus med prefabelement : En jämförelse mellan en platstillverkad konstruktion och prefabelement från Masonite Lättelement AB

This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020..
