Renewable energy and the charging of electrical vehicles will increase in the future. Therefore the risk of outages is also increasing, partly because renewable energy is intermittent and the production amount can change fast. Charging electrical vehicles is often demanding high effect in short time, which could make faults occur. It takes more advanced technology to short the outage time. Today Övik Energi has high reliability in the power grid, but in order to maintain the reliability, it is time to prevent problems that can occur in the future. This thesis has presented a suggestion for the placement of fault detectors Protrol IPS2, in which a total of four detectors is proposed.

The purpose of this study is to analyze how the parties (USA, Great Britain, UN and the European Union) legitimize their intervention in Bosnia-Herzegovina as seen from without the conceptions of sovereignty and intervention. USA and the UN have legitimized their intervention on security reasons. The American president, George W. Bush, claimed that democracies never engage in war with each other and that democracies were prosperous just because they were democracies. According to the president, that is why it is important to democratise the whole Balkan region to protect the international community from terrorism which grows in unstable and undemocratic states.

This essay deals with the support and help offered to elderly people over 65 with mental disabilities out of personnel from a special support team. We have chosen to use the qualitative method to answer our questions. We have four semi-structured interviews with all staff from the support team we have been in contact with, three nurses/nursing assistants and project manager for the support team. We have recognized five themes and divided the text into six different categories and disciplines that answers and highlights the importance of meeting clients' needs, increase their independence and quality of life. Our theme is security, continuity, time, treatment and relations.

One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

The purpose is to illustrate the phenomenon of self-harm from a social psychological and sociological perspective. The purpose is furthermore to examine the role social relationships play in the individuals´ self- imagine and what role does identification play for anyone who harm themselves? We want to examine in what way social relationships are important and how they function for individuals who harm themselves, both once they have started to harm themselves, and if the relationships in any part caused the cutting to begin with.Questions:How do individuals shape their identity based on self- harm? Which self-image do individuals have who self-harm? Is there anything in the person's previous social relationships that have caused them to begin to hurt themselves?Method:In this paper we have analyzed five autobiographies. We have used open coding from grounded theory as analytical method and subject positions based on discourse analysis.Theory:We have used the Cooley concepts looking glass self, Foucault's theory of power, Giddens' concept of ontological security and existential anxiety.Results and Analysis:We found six different categories that we thought were central. These were negative self-image, guilt, lack of family support, negative experiences of others' views, the protective identity as self- harmer and insecure social relationships in school.Conclusion:The self-harming is a very complex behavior.

The purpose of this thesis is to find out the reasons and perhaps some answers to the problem as we see it, the sickness benefit expiration of those who experience this. By this said we have also taken into account the different laws and adjustments in the long-term sickness benefit, but also major reformation of the security net in the Swedish society. The efficiency of the law on passive long-term sickness absence was added in July 2008, but was later in January 2010 supplemented. The purpose of this law wasn?t only to reduce the long-term sickness absence but also to reduce exclusion.

Background: The number of older people is increasing in Sweden. The elderly patient often requires a more complex type of care, than younger patients. The concept of frailty is often used to describe individuals who have a high biological age and a decreased physiologic reserve which could be associated with acute illness and an increased vulnerability. Emergency medical care today is not suitable for elderly patients and adaptions for these elderly patients and the demands this places on the health care is necessary. Mölndal Hospital emergency department has around 42 000 visitors per year, many of the clients have a high age.

The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

This master thesis has been carried out as a prototype development project. The project hasbeen performed in cooperation with ÅF Combra AB. The purpose with the master thesis is toconstruct a Bluetooth interface between an accelerometer and a smartphone and constructinga physical prototype containing an accelerometer. This is done to test a new user interface tomobile phones. The master thesis has also included a research about the possibility toimplement distance measuring with Bluetooth.
