The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.

Because of among other things the globalization and a focus on core competencies knowledge has become very important for the companies of today, especially for research-intensive companies. The problem is that the companies become more sensitive to how knowledge is created and spread, that is, how organizational knowledge is created. Especially sensitive are companies who are small, young and research-intensive. The purpose with this thesis is to explore how organizational knowledge is created in small, young and research intensive companies.The theory is based on a five-phase model of organizational knowledge creation and four modes of knowledge conversion described by Nonaka and Takeuchi (1995). These concepts constitute the foundation of the analytical model used in the thesis.The study is carried out by qualitative, highly structured interviews with low standardization.

Syfte: Syftet med uppsatsen är att beskriva och analysera hur kommunala energibolag resonerar vid val av avskrivningsmetod samt hur kommunala energibolag har förberett sig inför införandet och hur de förhåller sig till implementeringen av komponentavskrivningar.Teorier: De teorier som använts i uppsatsen finner vi vara relevanta och applicerbara utifrån studiens syfte och frågeställningar. Vi har bl.a. använt oss av Burns & Scapens ramverk som ingår i den institutionella teorin, vilket är den teori som studien utgått ifrån.Metod: Studien utgår ifrån den kvalitativa ansatsen med hjälp av semi-strukturerade intervjuer och dokumentgranskning.Empiri: Empirin innefattar intervjuer med 5 kommunala energibolag inkluderande granskning av relevant dokumentation.Slutsatser: Studien har visat att de kommunala energibolagen upplever avskrivningsval som en svårbedömd process som präglas av en inre tröghet på grund av påverkande faktorer och inrotade regler och rutiner. I och med tolkningen och införandet av BFNs regelverk avseende komponentavskrivningar har ett internt motstånd byggts upp på grund av svåra och godtyckliga bedömningar. Detta har bidragit till en spretighet, vilket har påkallat behovet av tydligare rekommendationer och direktiv.

Non-compulsory schools in Sweden should make use of the knowledge and experience that is available in society according to the aims and objectives of the Curriculum for the Non-Compulsory School System - Lpf 94. There are however only a few studies which have focused on the contacts between non-compulsory schools and society as represented by the business world in Sweden.The purpose of this study is to examine in what ways and to what extent non-compulsory schools are following the Curriculum by using the knowledge and experience of the business world. The perspectives have been: Which contacts in the business world and which working practices from the business world are implemented in teaching in non-compulsory schools? In what way do these contacts and working practices affect the teaching and learning of business administration? The purpose of this study is also to examine if the teachers in non-compulsory schools use business information and different kinds of business knowledge and experiences in order to keep themselves up-to-date regarding the business world. The perspectives have been: Are the teachers using up-to-date business information or business experience? Are the teachers applying a multicultural perspective in teaching business studies? In what way does this kind of information or first-hand experience affect the teaching and learning of business administration?The method used in this study was to interview seven teachers from two non-compulsory schools in Stockholm.

This examination paper is a study of the indoor climate in a theatre and a practice room for orchestras placed in Sickla in Stockholm. The designer of the ventilation system wondered if he had managed too make a good environment for the users and he also wondered which of the rooms that had the most desirable climate. The project includes polls for visitors, interviews of people connected to the rooms and measurements of the physical environment. The results show a small dissatisfaction about the thermal indoor climate, it?s a little bit to cold and the air draws.

The theory that concepts that are interpreted subjectively in building care creates problems in how the concepts are defined in practice within the current governing documents and guidelines for building care. This essay has studied concepts in the building maintenance literature to investigate whether there is consensus in compliance practice within the building process. In the study, 9 concepts have been investigated through conversational interviews and questionnaires answered by practitioners with extensive experience in building care processes. In the survey, an attempt is made, to measure how big or small the consensus is between practitioners who often need to collaborate within the building maintenance process. The investigation shows that existence of the concepts in building maintenance is very common in the theoretical literature examined but is almost completely absent in the craft area. Since laws, regulations, principles, and guidelines have defined concepts to support the decisions in the building maintenance process, it can be concluded that there is a lack of practice for compliance.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Companies today are facing more and different kinds of demands from the society and their stakeholders. It is no longer enough to just deliver the products, and not just the quality of the products that matter. The consumers are getting more conscious about the many ways in which companies affect the society and the environment in which we live. The financial sector, that among others includes stakeholders such as insurance companies, banks and fund companies are starting to realise the importance of the non- financial issues that companies are encountering. Analysing the companies sustainability when it comes to social and environmental issues, has become an increasingly important factor when for example choosing companies to invest in.
