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.

Miljöbalken är en svensk ramlag som syftar till att skydda människors hälsa och miljön på ett hållbart sätt, men i och med att balken är en ramlag kanden också ge upphov till tolkning. Förordningar och föreskrifter tillsätts för att tydliggöra miljöbalkens regler och minska detta tolkningsutrymme. Enyrkesverksam grupp som i sitt dagliga arbete kommer i kontakt med miljöbalken är miljö- och hälsoskyddsinspektörer. Denna kvalitativa intervjustudiesyftar till att undersöka hur inspektörers arbete och upplevelse av tolkningsutrymmet har förändrats sedan miljötillsynsförordning 2011:13 trädde ikraft, då förordningens syfte är att tydliggöra ansvarsfördelningen av kemikalietillsynen. Inspektörernas upplevelser av tolkningsutrymmet analyserasmed hjälp av Michael Lipskys teori om närbyråkrati.Studien visar på att majoriteten av miljö- och hälsoskyddsinspektörerna upplever ett tolkningsutrymme i miljöbalken, och att inspektörerna kandefinieras som närbyråkrater då de har ett stort inflytande på hur lagen implementeras.

Introduction: Basic Body Awereness Therapy (BBAT) is a treatment developed to treat different kinds of psychiatric diagnoses, but also to prevent the emergence of any other unhealthy conditions. The treatment is aimed to increase the body control and conscious breathing but also requires mental awareness.Aim: The aim of this study is to, based on social cognitive theory, describe patients' experiences of BBAT performed as group therapy.Method: The study design was qualitative with an inductive approach. Five people were interviewed after a BBAT group treatment in primary care. The data was collected by individual interviews with semi-structured questions and the interviews were analysed by qualitative content analysis.Result/Conclusion: The participants experienced increased body awareness and implemented BBAT strategies even though the treatment frequency was insufficient. BBAT was described as helpful used to regulate intensity level, stress management and facilitate breathing.

Abstract The main subject of this essay is conflicts at work and the effect it has on the employee´s health.  I can through various reports read that bad health at workplaces is too high and that conflicts are a reason. What can be done to the work environment so it will be better from a psychosocial perspective? Sweden has a regulation that makes the employer responsible to work for an improvement in the work environment; can these regulations be used in purpose to reduce conflicts?My first question concerns the possibility to establish preventive procedures in the workplace systematic work regarding to improve the work environment. My second question is about the obligations of the employer to attempt to reduce conflicts at the workplace and the third question regards the documenting and monitoring of conflicts and the preventing work to reduce them. The purpose of this essay is to clarify how conflict preventive work can be included in the Systematic work environment management.

This report is a Master?s Thesis performed by Andreas Adolfsson and David Jacobsson atChalmers University of Technology. The purpose of this master?s thesis is to evaluate anew method for load-shedding, the voltage controlled underfrequency load-sheddingdeveloped by ABB. This report presents a comparison between conventionalunderfrequency load-shedding and this new method for load-shedding.

This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..

Syftet med detta examensarbete är att få en bild av hur eleverna ser på motivationen under matematiklektionerna, samt om eleverna upplever någon skillnad mellan låg- och mellanstadiet i matematikundervisningen vad gäller motivationen.I bakgrunden presenteras motivation utifrån några olika definitioner. Olika begrepp inom motivation så som inre och yttre motivation, prestationsmotivation och flow beskrivs samt att tre olika teorier belyses.Studien är gjord i Kalmar och sammanlagt har 23 elever intervjuats, 11 elever från årskurs 3 och 12 elever från årskurs 6.Resultatet visar på att det är olika faktorer som inverkar på elevernas motivation men att det framförallt är elevernas inre motivation som påverkar. För att eleverna ska uppleva matematiken mer motiverande krävs dock att det används mer praktiska uppgifter så som spel och lekar i undervisningen. De elever som medverkade i undersökningen upplevde att matematiken är mer motiverande på mellanstadiet då uppgifterna är mer utmanande och eleverna ser en användning av matematiken i det vardagliga livet..

Bakgrund:                   Under senare år har de börsnoterade bolagens styrning kommit att intressera samhället. Ett viktigt fenomen i bolagens styrning är styrelserna. Under de senaste 15 åren har omfattande regleringar införts för att klargöra och definiera hur styrelserna i de börsnoterade bolagen skall sättas samman och arbeta.Syfte:                            Syftet med denna studie är att undersöka om, och i så fall hur, det svenska styrelsenätverket förändras efter utvecklandet och implementeringen av en reglering. Vår ambition är att ge förklaringar till varför eventuella förändringar sker.Avgränsning:               Studien har utgått från Svensk kod för bolagsstyrning som ett fall av reglering för att se hur denna har påverkat styrelsenätverket.Metod:                          En social nätverksanalys av styrelseledamöternas nätverk har genomförts. Studien omfattar bolag noterade på en svensk reglerad marknad med säte i Sverige.Slutsats:                        Studien påvisar att införandet av en styrelsereglering inte behöver leda till förändringar i styrelsenätverket.

This work studied the information flow and information handling among different parties. The study focused on how educational materials on national tests from The Swedish National Agency for Education is managed by school principals and teachers and how the information is passed on to students. The data material was based on observations and interviews at two different high schools. Six teachers and their classes and principals participated in the study. The Agency was also interviewed.

Dagvatten kallas det regn- och smältvatten som rinner av från hårdgjorda ytor i stadsmiljön. Detta vatten för ofta med sig stora mängder av föroreningar som tungmetaller, näringsämnen och oljerelaterade ämnen, vilka kan göra stor skada om de når recipienter. För att rena dagvattnet och därmed minska föroreningsbelastningen byggs det allt fler öppna dagvattensystem som t.ex. våtmarker och dammar. Studier har visat att dessa system har hög reningseffekt och dessutom är de kostnadseffektiva.

Climate changing is a growing problem for many countries and communities over the world. The cities has a huge work to deal with in their reforcements of their cities to be resilient ones. This thesis makes an effort to investigate and illuminate some of the problem the cities has to solve related to flooding, hazards, erosions, rising sea levels and crotches. This thesis will help to find solutions that international and national efforts has produced and handed out to each other. A lot of communities are charing their excellent tools that works for them.

In the light of some company scandals the Swedish Code of Corporate Governance, the Code, was introduced in the year of 2004 to reinforce confidence in how Swedish listed companies are managed. As many of the other European codes of corporate governance, the Swedish Code is based on the principle of ?comply or explain?. The need for corporate governance regulation arises from the inherent conflict of interest between owners and managers. This conflict is limited in companies controlled by a family in contrast to companies that lack a strong owner.

The case study investigates study association representatives? perspectives on the activities of the popular education within the social sector in Örebro and why they are organized. It further investigates the cooperation and dialogue between the study associations and the municipality of Örebro regarding this activity. The study is based on critical realism. A questionnaire survey was conducted among all ten study associations in Örebro, combined with qualitative interviews with representatives from six of the active associations.

A company reconstruction is an alternative procedure, for companies in payment difficulty, to receivership. Those in any kind of relationship with the ailing company ends up in a dif- ficult situation at a company reconstruction, as in any case when someone is in financial difficulties. Not only is there a risk for the providers not to get paid, the costumers are also at risk if the reconstruction company does not fulfil their agreement. These kinds of rela- tionships are controlled by a contractual relationship. Therefore the regulation has to con- tain how to deal with these contracts when the ailing company no longer can fulfil its obli- gations of the contract.

FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among  others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.
