Förbrukningsreduktion : Ett alternativ till gasturbiner som snabb aktiv störningsreserv?

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Arbetsmotivation trots osäkra arbetsvillkor? : En kvalitativ studie om arbetsmotivation hos anställda med osäkra arbetsvillkor

Studiens syfte är att undersöka arbetsmotivation och motivationsfaktorer hos anställda med korttidskontrakt på ett företag som arbetar med sådana praktiker. De formulerade frågeställningarna är: Hur anser anställda med korttidskontrakt att deras arbetsmotivation påverkas av de osäkra arbetsförhållandena? Vilka motivationsfaktorer är viktiga för dem? Vilka strategier har de för att motivera sig? Empirin bygger på intervjuer genomförda med 6 respondenter på ett företag som utgör typfallet för studien. Den teoretiska referensramen består av Deci och Ryans definition av inre och yttre motivation och Herzbergs tvåfaktorsteori. Tidigare framforskade resultat med koppling till nämnda teorier har legat till grund för databearbetningen.Ur resultatet kan utläsas att anställda med osäkra arbetsvillkor motiveras av givande arbetsuppgifter, att genom sitt jobb ha möjlighet att hjälpa andra människor.

Kuratorers arbete med gymnasieungdormars psykiska ohälsa: en kvalitativ studie

The overall aim with this essay was to study how counsellors at upper secondary school work with mental illness among youths and compare this with what research and theories advocate. This because there has been a rise in the number of people, especially in the age-group 16-24 years, suffering from different degrees of mental illnesses. The school can in some aspect contribute to cause mental illness but it also consists of good opportunities to offer counselling and work to prevent mental illness among the students. This study consists of five qualitative interviews and two short telephone interviews with school counsellors. During the interviews they expressed their thoughts concerning factors that causes mental illness among youths and gave an account of how they work with prevention, counselling and collaboration.

Vem vinner: fackboken eller den skönlitterära boken? : en studie över lånevanor i en 3:e klass i en mindre by i norra Sverige

The purpose of this thesis is to investigate the habits of borrowing books among third-grade pupils. My aim is also to study what significance their teacher and the librarian have on the pupils? borrowing habits.

The empirical material consists of open-ended interviews with in all ten researchers. All of them work at the Swiss-Swedish Technology Company ABB's research laboratory in Västerås. The thesis is based on the opinion that the scientific knowledge production has become commercialised and that the scientific communication is going through certain changes.

Utbyggnad Av Eriksberg

During the years of development in the 60s and 70s the need for new housing in Sweden arose. Sweden was going to be the most modern country in the world. This period has later been called ?the time of the big programmes?. One of the parts in this building of a welfare society was a large policy of building politics with few counterparts in history.

Kommunikation och samarbete. En studie av bibliotekariers och lärares förhållningssätt gentemot varandra gällande samarbete

The purpose of this paper has been to study the relationships and attitudes of a few teachers and librarians as to their co-operation in a combined public and upper secondary school library and to find out what circumstances there may be to exert an influence on their work. The paper has been based upon qualitative interviews with upper secondary school teachers and librarians as well as on studies of literature relating to our issue. We believe there may be different approaches to the learning process, as these are the relations and attitudes of two professions from different trades. That is why our point of departure has been Roger Säljö's theory about learning and, in our analysis, a few of Jean Donham van Deusen's ideas of joint planning and flexible timetabling. All respondents agreed that co-operation could be better, but the teachers were of the opinion that it must not interfere with their time.

Skolans kvalitetsredovisningar och isomorfism : - En innehållsanalys av kvalitetsredovisningar 1997-2006

AbstractIn 1997 a regulation were introduced to the swedish school system, Förordning om kvalitetsredovisning i skolor m.m SFS 1997:702 (Regulation about account of quality works whithin the school system). The preceding discussion noticed that municipalities and schools lacked in their progresive quality work. Messures had to be taken. Since the introduction of the regulation the government has decreed changes and additions to the original regulation. This has led to changes of substance and form in the quality work account to the administration during time.

Vad kostar korttidssjukfrånvaron?

Bakgrund och problem: Långtidssjukfrånvaron har länge varit ett uppmärksammat problem och flertalet åtgärder har satts in för att minska denna. På senare tid har korttidssjukfrånvaron dock lyfts fram som ett ytterligare problem och erhållit en större uppmärksamhet i takt med dess ökning. Korttidssjukfrånvaro syns inte i offentlig statistik förrän efter den åttonde dagen och är därmed svår att studera. Likaså kan kostnaden för korttidssjukfrånvaron vara svår att fastställa eftersom korttidssjukfrånvaro består av både direkta- och indirekta kostnader.Syfte: Syftet med denna studie är att beskriva och förklara hur stora kostnaderna är för den korttidssjukfrånvarande socialsekreteraren på en enhet i Växjö kommun. Utifrån dessa kostnader ska sedan en metodik utformas för att kunna fastställa en standardkostnad för vad korttidssjukfrånvaro per timme kostar.Metod: Under studiens gång har en abduktiv forskningsansats, en kvalitativ forskningsstrategi och en fallstudie som undersökningsdesign nyttjats.

Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern

Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.

Folkbibliotekarien och det livslånga lärandet En undersökning av ett projekt till stöd för vuxenstuderandes livslånga lärande

The purpose of this master thesis is to investigate issues concerning lifelong learning and the role of the public librarian. This is done by examining LärForum Forum for Learning, a project initiated at a public library located outside of Stockholm, with the aim of supporting adults lifelong learning. The major questions raised in this study are: How do the seven librarians interviewed define lifelong learning and how do they perceive their own role in relation to lifelong learning in the public library? Do they work with adult learners in a different way than they do with "ordinary" users of the library? Has their conception of their own role as a public librarian changed as a result of LärForum, and do they find it necessary to acquire new skills because of the project? Data was collected through interviews and observation, and the study is a qualitative case study. The main results are that the librarians see their role in lifelong learning in the public library as self-evident, and they see lifelong learning mostly as learning for an individuals personal development.

Metoder för kartläggning och analys av nätförluster i lågspänningsnät

An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.

Public WLAN - The interaction between venues and WISPs

Purpose: The purpose is to research different co-operations between venue owners and WISPs, when WLAN is deployed in a public space. The aim is to establish viable business models for the interaction between the two vital actors in the public WLAN industry. In this work, the advantages and disadvantages of revenue and cost sharing will be defined, along with technical and commercial issues that need to be resolved. Methodology: A number of case studies of the current situation have been conducted in the most attractive venues for WLAN, airports. As the public WLAN market had most widespread adoption and is most mature in the USA, case airports were chosen both there and in Scandinavia.

Ge oss ett strukturerat men flexibelt stöd! En kvalitativ undersökning om familjehemsföräldrars upplevelser av stöd: sett ur ett utvecklingsekologiskt perspektiv

The purpose of this study was to examine how the foster parent's need of support is provided. The study was built upon a qualitative method with interviews with ten foster parents. More specifically, its aim was too find out how the foster parents themselves looked upon how their need of support, and from whom the support was provided. According to the law, it is the social services obligation to provide the foster parents with all the support they could need. The picture the media sends out is different from what it should be because according to them, the social services fall short in the follow-up and also the support of the contact with the foster parents.

Akusmatisk gestaltning: Filmljudets betydelse bortom bildens ramar

Kandidatarbetets innehåll undersöker och diskuterar frågeställningen: ?Hur påverkas narrativet i en film genom att gestalta ljudet akusmatiskt??. Med hjälp av teorier och slutsatser från filmteoretiker så som Michel Chion, David Sonnenschein och Klas Dykhoff, har vi till kortfilmen Alla ljuger skapat en ljudläggning med fokus på narrativa ljud utanför den rörliga bilden. Vårt resultat syftar till att skapa grunden till en svensk standardisering av de existerande teorier och metoder för gestaltning av akusmatiska ljud i film. The content of this bachelor thesis examines and discusses around the question: ?How does the implementation of acousmatic sounds affect the narrative of a motion picture??.
