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.

The purpose of this study was to investigate and describe the views on how the mediation program Programa Árbol Sicómoro affected inmates?, convicted of murder, own lives. Research questions:? To what extent, and how, has the mediation affected the convicts? views upon themselves and the crime they have been convicted for.? To what extent, and how, has the mediation brought any change to the convicts? imprisonment and if it has changed their look upon the future.The study has been executed using qualitative method. Materials from seven profound interviews have been analysed and condensed using terms from restorative justice and self-image theories.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Human Resource Management (HRM) has an increasingly strategic role in today?s organizations as the supply of managers is an integral part of the strategic work. In order to retain competence and knowledge, firms are usually designed so that the employees can develop their careers within the firm. Company X is a company in the financial sector and is an example of such firm. However, at Company X: Department Y, very few employees apply for the management positions when they are announced.

Media spelar stor roll i vårt samhälle. TV är det massmedium vi använder i störst utsträckning. 90 procent av barnen som är mellan nio och fjorton år ser på TV dagligen. Det är inom denna åldersgrupp (närmare bestämt 11-12-åringar) vi valt att göra vår undersökning. Undersökningen berör frågor som vilka TV-program barnen ser på och om barnen kommer i kontakt med dokusåpor? Vi kommer även att se närmare på vem barn tittar på TV med och om det finns någon skillnad mellan pojkars och flickors TV-tittande.

Det här är en intervjustudie om 22 intervjuer med gymnasieelever vid Barn och fritid-, Natur- och Fordonsprogrammen om deras sociala bakgrunder, deras föräldrars yrken och elevernas syn på sina val av program om de upplever någon orättvisa i det observerade sambandet som kallas den sociala snedrekryteringen. Syftet med studien är att ta reda på hur eleverna upplever sin situation i ett rättviseperspektiv. Den här studien bekräftar det nämnda sambandet, de flesta elever väljer program och vidare studier och arbeten i nivå med sina föräldrar. Detta är särskilt tydligt vid Natur- och Fordonsprogrammet. På Barn och fritid var det mera blandat.

Hälsofrämjande och förebyggande arbete rörande barn och elevers hälsa och utveckling berör en rad olika arenor i samhället, jag har i min studie valt att koncentrera mig på skolan och de förebyggande program som kan finnas där. Mitt syfte med studien var att belysa hur valet av dessa förebyggande program går till, vem beslutar att de ska användas och vem efterfrågar programmen. Jag har i en kommun genomfört kvalitativa intervjuer med aktörer på olika nivåer i skolsystemet, ordföranden i barn- och utbildningsnämnden, förvaltningschefer i skolnämnderna samt tre rektorer, alla med rätt och förmåga att fatta beslut i sin verksamhet. Att jag valde de olika nivåerna i skolsystemet beror på att skolan ofta ses som en generell institution istället för det mångfald av olika organisationer som den faktiskt är (Karlsen & Persson 2004). Jag har därför valt att i min studie utgå från Gunnar Bergs (2003) teoriSkolan som institution och skolor som organisationer samt ett struktur- och aktörsperspektiv som en grund för att belysa det i förhållande till mitt syfte.I kommunen där jag genomförde min studie så var användandet av ICDP (International Child Development Programmes) och SET (Social och Emotionell Träning) utbrett.

International reading comprehension studies, like PIRLS and PISA, state that the reading comprehension of Swedish students has decreased significantly since 2000. As a consequence, the National Agency of Education has made reading comprehension teaching a prioritised field in terms of further education for teachers. There has also been a change in Lgr 11, the national curriculum for compulsory school, where it is stated that teaching in reading strategies shall be a part of the central content throughout compulsory school. When the pupils reach upper secondary school level, reading comprehension education is no longer a part of the curriculum. Today, students at upper secondary school for individuals with learning disabilities currently share the same curriculum as the ordinary upper secondary school.

Aim and Problem statement The study aimed to investigate views on physical health amongst patients in methadone maintenance program, which is a subject little explored. Previous studies suggest that methadone patients are at risk developing illnesses related to the metabolic syndrome and an unhealthy lifestyle. Methadone also has side effects such as weight gain and irregular levels of glucose. Method This qualitive study included seven interviews with patients in the methadone maintenance program in Uppsala. Qualitive content analyses were performed Findings Content anlyses gave the theme: The view on physical health is a stuggle after normality were ambivalence of lifestyle changes and alienation causes instability in helath.

Syftet med min undersökning är att ta reda på om före detta elever som tog examen 2005 på Industriprogrammet arbetar kvar i branschen och om de valde rätt gymnasieutbildning för sitt fortsatta yrkesliv. Metoden som jag valt att använda i mitt forskningsarbete är att intervjua en klass bestående av 17 elever. Jag har ställt frågor beträffande deras gymnasieval, om de arbetar de kvar i den bransch som de utbildade sig till eller sysslar de med något annat och vad de tyckte om utbildningen. De resultat som jag har kommit fram till pekar på att eleverna sökt sig till programmet av olika anledningar. För vissa elever så räckte inte poängen till att komma in på de program som de önskade, men de flesta tycker att de valde rätt utbildning. En anledning till valet var att det leder direkt till arbete efter gymnasiet..

Now a day?s there is dramatic change from traditional to digital information processing in construction industry. This change can be visualized in the project concept stage where it now has accessibility to join all the data in one place. Location-based planning technique simplifies scheduling by visualizing the schedule efficiently and has many advantages such as might shortened the project period by about 10 - 20 % if the company uses location-based technology, reducing risks in many ways by maintaining production continuity and identify collisions between things etc. Vico Office software has been used for Location based planning technique and in this thesis.The purpose of this thesis work was to demonstrate how location -based planning technology change the scheduling stage in Peab, potentially reducing the project time.

Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

European Union has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket?s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of renewable energy.Passive House is a set of requirements from FEBY designed to build energyefficient buildings. This is achieved by reducing loss of heat through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report?s issues, including Anebyhus?s energyperformance, requirements for the manufacturing and assembly, how theenvelope must be improved to fulfill the requirements for the Passive House andwhat energy calculation programs are available on the market.The report aims to provide solutions for energy efficient houses that are adaptedfor production of house building.Two visits to Anebyhus has been done to study their manufacture and assemblyof building elements.
