Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Ett utforskande av interpretation utfört i musik, akvarell och ord. En närgången bild av en levande musikalisk process studerad från en inre kärna. Arbetet består utav denna text, tre konserter från våren och sommaren 2013 som dokumenterades i DVD-format, ljudupptagningar av improvisationer och akvareller skapade i tiden för arbetet. Arbetets kärna, ögonblicksbilder från insidan av själva processen, presenteras i en egen del av arbetet och omsluts av förklarande, reflektioner och tankar. Författaren spelar viola och upplever synestesi..

This report analyzes and examines a hypothesis for finding a method to optimize thelength of the delubrication process time based on a total charge weight. The work hasfocused on the holding time for delubrication and the total charge weight.An important step in the manufacturing chain of cutting tools is when the greenbodies undergo the sintering process. Today, the delubrication step has the sameprocess time independent of the total charge weight. An implementation of a methodto adjust the delubrication process time would give more consistent quality of thecutting tool´s internal characteristics but also reduce the time course of the sinteringprocess. In the present project two methods for this goal were tested, thedevelopment of an algorithm and a weight interval subdivision with associateddelubrication process times.During delubrication a pressure increase is observed due to the decomposition of thePEG in the powder mixture.

Examensarbetet berör utvärdering och förbättring av kvalitetssystem vid Pfizer i Helsingborg. Data har samlats in, analyserats och därefter har förbättringsförslag tagits fram. Huvuddelen av datainsamlingen består av intervjuer som sedan analyserats med hjälp av teori inom TQM och gällande ISO standard. Övriga delar av datainsamlingen består bland annat av benchmarking. Svagheter med systemet har identifierat och rör bland annat, avsaknad av helhetsbild, kontrollinriktat samt suboptimeringar.

This thesis work has introduced process orientation at the printing company Color Print Sweden AB. The outcome ofthis work is a survey of the work flow at the prepress department. To visualise the production process at the companya comprehensive mapping of the main process, order-to-delivery, has been made. The work has detected a couple ofcritical elements in the existing process. These elements are the following: initial check of material delivered to the prepressdepartment as well as the control made of the plotter print-out, digital test print and plate.

The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.

Every plan and program decided on by an authority or municipality, where the environmental impact can be considerable, must be environmentally assessed according to Environmental Code, the Planning and Building Act (PBA) and the Regulation on Environmental Impact Assessment.The purpose of this study is to examine the Environmental Impact Assessment (EIA) for The Region Development Plan for the Stockholm Region, RUFS 2010. The plan was approved by at that time the Regional Planning Office (Regionplanekontoret), which procured the process by consultants. RUFS 2010 includes two merged plans ie. a regional Development Plan (RUP) and the Regional Spatial Plan for Stockholm. It was necessary to establish an environmental assessment of RUP, but not for the regional plan.

The idea for the project emerged when Nilorn wanted to get better control over their supplychain and improve operational efficiency. The company also want to reduce their expenses inthe continuous process of improving profitability. By choosing the right option oftransportation and mode of transport there are large potential savings for the company. Thisenables Nilorn to reduce the transportation costs and strengthen the environmentalresponsibilities by reducing their environmental impact.The flow of goods within Nilorn has over the past years increased significantly and most ofthe gods today is transported by air. The aim of this thesis is to analyse the supply chain of thecompany and evaluate the potential economic savings in this area.

The final stage of a designers work is always a bit tricky. Design is an abstract phenomenon and no one can tell when a design is really finished. The design process that designers work within has been thoroughly studied but cannot be truly mapped with strict constraints which the designer can follow to succeed. Therefore, in this paper we take a look at the final stage in the design process. The main goal is to get more knowledge and highlight key factors about what designers face when they are about finish their design or what forces them to leave a project that can stay in development for eternity.

Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.

Each student in elementary school will under current policy documents have an individual development plan (IEP) from 1 January 2006. The plan should primarily aim for a higher goal achievement, but also to the student to gain a greater understanding of their own learning process and knowledge. My experience is that some students, despite efforts IUP have difficulty seeing their own learning process and it has been the starting point of my study. The aim of the study has been to investigate and analyze teachers work with individual development plans from the first grade to the sixth grade from a teacher's perspective. The goal was to identify strategies and techniques that could help develop IUP as a tool for the student's learning and understanding of their own learning process.
