Framtidens driftcentral : En analys av den framtida driften av ett svenskt elna?t

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.

Globalt Ansvar : socialt ansvar eller organisatoriskt hyckleri?

Background: Ambiguity and confusion of ideas within the area of social responsibility have led to that companies not really know how to work with these types of questions. One way for companies to deal with their social responsibility is to affiliate to an initiative that exists and through this show their standpoint. One of these is Globalt Ansvar, a Swedish governmental initiative that is based on Global Compact?s principles and the guidelines of OECD. What does it mean for the companies when showing their point of view? Is this a way to gain legitimacy?Purpose: The purpose with the thesis is to judge if organisations? work with Corporate Social Responsibility gains more legitimacy by affiliating to Globalt Ansvar.Research method: A survey made through telephone interviews with representatives from all of the fifteen Swedish companies which today are affiliated to Globalt Ansvar.Conclusions: In order to give the affiliated companies more legitimacy, Globalt Ansvar has to be a legitimate initiative.

Värmeåtervinning ur spillvatten i befintliga flerbostadshus

Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.

Yrkesrelevant Gymnasiearbete på El- och Energiprogrammet

The purpose of this development project is to create a model for working with a high school project in Electrical and Energy Program. It should be conducted in a form like companies do according to the goals from The Swedish National Agency for Education. In order to fully perform this we use the concept of Young Entrepreneurship. The model is created according to the new conditions from The National Electrical Safety Board. There is now an exception saying that a student during education is released from the demand of employment that is the normal procedure where you are under supervision from a certified electrician. During the project there has been theoretical and practical examinations in order to clear out the advantages and disadvantages using this model, but also to examine whether it is useful in the future and to what extent it can be used. The result indicates that the model is useful and fulfills the goals from The Swedish National Agency for Education but that the model has its limitations and difficulties.

Överklagande och dess roll inom bostadsbyggandet : En granskning av plan- och bygglovsprocessen

The aim of this diploma work was to obtain a review of the appeal process in Sweden under the Planning and Building Act and the possibilities of appeal in the planning and building permit process. The work was intended to identify potential problems surrounding the appeal process and possible efficiency measures. The goal was to form a report that provides a satisfactory overview of the appeal process in theory and practical application as well as provide relevant concrete proposals on how the appeal process can be streamlined.Background and facts surrounding the work were taken from different types of literature and through several interviews with representatives in government, industry and politicians.The main problems related to the appeal process are in the long processing times and the high number of appeals. There is a great interest to streamline the appeals process and the government is going to launch studies in which possible future actions will be investigated.It is possible to appeal for up to two instances before you need a so called ?leave to appeal? in order for your complaint to be passed on to the next instance.

Fuktproblem i chilenska småhus

Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.

Perspektiv på prostitution - En analys av hur Sveriges lösningar på prostitutionsproblemet tar sig uttryck

In Sweden, prostitution is politically defined as a social problem, more precisely, as a form of male violence against women. The definition is distinctly manifested in the government bill Kvinnofrid, characterised by the unique Swedish law that prohibits the purchase of sexual services.This thesis examines how the Swedish solutions of prostitution are carried out. By interviewing central actors working with prostitution in different ways we aim to answer the question: What measures are taken to decrease prostitution and what implications does the Swedish solution have?The analysis is divided into two parts. First, we analyse the concrete measures taken against prostitution ? what is done, how, and why? Second, we analyse the complexity of prostitution measures by applying complementary analytical perspectives: the symbolic and the discourse perspective.The study shows that measures taken to decrease prostitution vary and depend on individual actors? understandings of the political definition.

Internkommunikation - idag och imorgon. En kvalitativ studie av personalens syn på Blå Ställets internkommunikation

Aim: The main purpose of this thesis was to investigate how the employees experience theinternal communication and to examine the channels they communitace trough betweenthe departments at Blå Stället in Sweden. This task was given by the unit chiefs at thecompany who?ve seen a need to investigate and improve their internal communication.The goal is therefore also to produce concrete and well-founded proposals on how theinternal communication can bee improved at Blå Stället. Relevant Theoretical frame ofreference was internal communication, information, communication channels, formaland informal communication. To collect data from employees I made six interviews,one from every department and two informers.

Chatt - ett nytt sätt att kommunicera med bibliotekarien

This thesis presents a new way of providing library users with reference services, namely chat (text based digital reference service in real time). Our research questions focus on the role of reference service, a comparison of chat reference to other reference forms, and the interest for real-time, digital reference. Our literature review covered the areas of digital reference and reference theory, the results of which showed that an ongoing debate hardly exists among Swedish librarians on the topic of reference work. We interviewed librarians from the three different Swedish chat reference projects existing at the time of our study. Most interviewees were very positive about chat reference.

Toleransproblem vid produktion och montering av prefabricerade betongelement

The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.

Det litterära spädbarnet ? en undersökning av folkbibliotekens program för de allra yngsta barnen

The objective for this Master?s thesis is to study literary programs for infants at six Swedish public libraries, their relevance and importance for infants and how the infant?s perspective in the program design and implementation is taken into consideration. The questions I pose are: In which way do the programs take the infants need for development and their literary prerequisites into consideration? Which functions can the programs have for infants? I have used a qualitative method, based on deep interviews with six library staff, working with literary programs. A model was developed based upon Daniel Stern?s theories of the interpersonal world of the infant together with Joseph Appleyard?s reading development theory.

Vad var egentligen problemet? : en analys av SOU Framtidsvägen och ämnesplanen i historia

The aim of this study is to analyze how problems are represented within SOU 2008:27. Further more, the aim is to analyze how the new subject plan for history can bee seen as a product of this document. The method used, and the theoretical frame of the study, is based on Carol Lee Bacchi?s ?what´s the problem represented to be?? approach, which basic principle is that policies are filled with representations of problems and that these representations need to be examined. These problem representations are then themselves subject for scrutiny, the second step being an analysis of the texts presumptions and assumptions concerning view of man and perception of knowledge. The results show, among other things, that a problem representations can be found in the SOU; the school system is too vague and unclear.

Påverkan på elektronik och sensorer i radiologisk miljö

The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..
