RCC-Jordfelsskydd, mätmodul för övertonsanalys
The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.
En Fallstudie av Implementeringen av EU:s Minoritetsskydd
The intention of this thesis in political science is to understand how the European Union fights and prevents discrimination against the Roma minorities in Sweden and Romania, and how the implementation works in reality. The study consists of defining what it means to be objectively discriminated, what ethnicity really means and how the implementation process consist of a comparison and statement has been made by the national governments and comparing how two socioeconomically different member states handle EU directives and implement them in Sweden and Romania. The main findings of this study was that EU policies lack the capital and explicitness that is needed for great results to be accomplished and that the governments in both countries have different issues with implementing the protection of the human rights and Roma culture, and that EU needs to be more practical and develop in a faster pace. .
Socialarbetares förståelse av våld i nära relation : En vinjettstudie med barnavårdsutredare
Social workers ideas about what domestic violence is influence their ability to recognize vio-lence in cases where this occurs. Social workers awareness and understanding of domestic violence can also influence the handling of these cases. Education on the subject domestic violence can increase social workers knowledge about, awareness and handling of violence. The present study aims to investigate how social workers in child protection investigations understand, recognize and interpret domestic violence and which interventions the social workers suggest. This is a qualitative vignette study in which semi-structured interviews was carried out with social workers working with child protection investigations.
Miljöinformation från teori till praktik.
The purpose of this paper is to investigate the process of transferring information from science to "the field" of environmental protection in Sweden. I have studied four Swedish environmental organizations, Greenpeace Nordic, WWF Sweden, the Swedish Society for Nature Conservation and Friends of the Earth Sweden to see how they search/get information. I have also studied the Swedish Environmental Protection Agency and its role as sender of information, since it is the authority which is responsible for environmental information in Sweden. I have used information and communication theories as a help to analyse my results. While working on this paper I realized that my methods were not the best.
Värmestrålning för förebyggande av isbildning på strömskenan
Detta examensarbete har utförts med begäran från Trafikförvaltningen. Arbetets huvudmål är att undersöka om det är möjligt att använda värmestrålning direkt mot ytan av strömskenan för att hindra isbildning på en kortare tid då absorptiviteten är som bäst..
Sms-lån : Kreditgivning med bristande konsumentskydd
The subject of sms-loans is examined by using primary and secondary sources?. This form of credit is formally independent from other obligations with a very short credit period and the amount of the loan is low. This form of credits is applied by mobile phones and on the internet by several companies, some of them are presented in this essay. These type of creditors do not come under any sanctions from the Swedish Financial Supervisory Authority as is customary for other creditors, they only need to register.
Varumärkesrätten inom EU : - ensamrätten i konflikt med EG: s konkurrensregler och reglerna om fri rörlighet för varor
The single market is one of the underlying ideas of the European Union. Free movement of goods and efficient competition are central for the function of the union and are therefore carefully protected by the Treaty of Rome. Exclusive rights of trademarks in the EU can be seen as a method of dividing the common market, preventing the free movement of goods and to be anti-competitive. What comes out of this is that there is a conflict between exclusive rights of trademarks and the rules of both free movement of goods and competition. The aim of this work is to see in which kind of situations the exclusive rights of trademarks can be a part of this conflict but also to study how this problem is resolved by the European Court.
Rostfria stålkonstruktioner och rostskyddsbehandling av stålkonstruktioner enligt Eurocode
Steel is an excellent material to build with, but consideration must be given to the fact that unprotected steel corrodes, rusts, therefore, as a rule, the steel must be protected in some way. This can be done by reducing the tendency of the steel to corrode by using stainless steel or by treating the steel with a protection method. The two most common methods of protection are corrosion protection paint and zinc coating. To determine the method, the corrosive category must first be evaluated and this is done in accordance to EN ISO 12944-2:1998.Stainless steel is available in many varieties but only some of them have properties that make them suitable for use as construction steels. There are many factors to be considered in the design of stainless steel to prevent corrosion from occurring.
Mot mer flexicurity?
Since the 2006 election, the debate surrounding the Swedish labour market policy has intensified. There has been a discussion about a need for change towards a more flexible labour market. An example of this is on the other side of the strait, in neighbouring Denmark. Their flexicurity model, ?the golden triangle?, is characterized by a flexible labour market, generous unemployment benefits and active labour market policies.
Intresseavvägningen i personuppgiftslagen - Det kommersiella intresset
Personuppgiftslagen (1998:204) är en lag som syftar till att skyddavåra personuppgifter. Huvudregeln i personuppgiftslagen är attsamtycke krävs från den som personuppgifterna tillhör för att de ska fåbehandlas. Till denna huvudregel finns det dock ett viktigt undantagsom stipulerar att om behandlingen är nödvändig får den utföras utansamtycke, om exempelvis ändamålet uppfyller ett berättigat intressehos den som ämnar behandla uppgiften som väger tyngre än denenskildas intresse av skydd för den personliga integriteten. När ettsådant berättigat intresse ställs mot den personliga integriteten blir enintresseavvägning nödvändig för att avgöra om behandlingen skallvara tillåten eller ej. Det berättigade intresset som upptar dennauppsats är det kommersiella intresset, som exempelvis omfattar ettföretags intresse av att behandla personuppgifter för att via direktmarknadsföring marknadsföra sina produkter.
SVERIGEDEMOKRATERNA ? ETT HOT MOT DE M?NSKLIGA R?TTIGHETERNA? En unders?kning av i vilka avseenden Sverigedemokraternas politik strider mot Europakonventionens skydd av minoriteters r?ttigheter
Right-wing populism has through the past decades flourished in several countries in Europe.
Research has shown that right-wing populism is, with its political starting point in ?the
people?, focusing on the majority and is sometimes excluding the minorities from the politics.
Since human rights regulations are mainly a protection of minority rights, the aim is to
examine if the politics of the Sweden Democrats, as a case of a growing right-wing populist
party, is a threat to human rights and in that case, in what respects. The thesis is supposed to
answer the question in what respects the politics of the Sweden Democrats contravene with
the European Convention?s protection of minority rights.
Statusbedömning och förbättringsförslag för startkedjemaskineri, startkedja och linspel för stränggjutningsmaskin
The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.
Behovet av förändrad köplag, med hänsyn till privathandeln, till följd av Internet
This paper considers the Swedish regulations of purchase taking the perspective of private persons as a starting point. The law of purchase from the year 1990 is applicable on a number of legal purchase situations where the contracting parties varies. Nevertheless, the law is mainly focused on the purchase between businessmen. This places private persons on level with businessmen, since they are given equal responsibility regarding legal knowledge and the drawing up of contracts. In order to get a deeper knowledge of the law of purchase and to reach an understanding of how it should be interpreted we have studied the government bill on the law, cases from the Supreme Court, doctine on the area and legal articles. The purpose with this paper is to examine whether the law of purchase from the year 1990 is too old to be applicable on private purchases today.
Ansvaret för tillämpningen av vissa familjerättsliga skyddsregler : Om gränsen mellan opartiskhet och etisk plikt som jurist
AbstractWorking as a lawyer demands not only legal skills, but also ethical ones due to the involvement with humans. The area of ethics is far from as regulated as the area of law is. The reasons for this are both historical ? as the area of ethics is, in comparison with the practice of law, a relatively new area, especially combined with the traditional work of lawyers ? and technical, since ethics is an area that seems difficult to regulate due to its adopting skills. Ethics looks different depending on which work area it addresses; who you ask; and in what situation it shall be enlightened.
Grundvattenskydd och markanvändning i tre olika länder- effekter för miljö och samhälle
AbstractDrinking water is an important resource on Earth both for humans and animals. Although most of the surface is covered by water only a small quantity is available as drinking water. Our manner of living creates a lot of pollution which has an environmental impact. Groundwater has a protracted turnover time in the soil and it can take many years before the effects of human impact are detected. The Swedish environmental object is ?Good groundwater quality? which aims to provide a safe and sustainable supply of drinking water today and in the future.
