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.

The change in the information society has affected the development of the labour market for information specialists and informants as well as their roles. Companies are now aware of the fact that information specialists have a variety of important skills and competence that is important for them. The goal of this thesis is to see what defines an information specialist and an informant and also to find out their situation on the labour market. The similarities and differences between the two professions will also be discussed in the thesis. The main method used is the investigation of the job advertisements in the journal DIK-forum from the year 2000 and year 2004.

This thesis is an investigation of Iranian immigrants and their use of libraries in Sweden. It isbased on a combination of a qualitative and a·quantitative method.Using a qualitative method, I give an outline of the history of lran from ancient times up to the present, as well as the different ethnological groups in Iran and their cultures. The main objective of this part is to clarify the contrasts between Iranian and Swedish cultural, social, linguistic and family structures, and also the characteristics of the crisis that most immigrants go through on their arrival in the new country. The qualitative method also involves structured telephone interviews with eight highly educated Iranians.This method was supplemented by a quantitative study through questionnaires of the attitudes· of lranian immigrants to libraries and reading. Iranians in Sweden turned out to be frequent Iibrary users.

 Title: Implementation of Balance Scorecard in public sector - a case study in the community of Tidaholm. Course: Thesis in business administration, 15 p Authors: Marie Ohlsson and Ola Pettersson Advisor: Henrik Linderoth Purpose: The purpose of this thesis is to investigate how the balanced scorecard can be formed according to the backgrounds in the community of Tidaholm. Methodology: We have chosen a qualitative case study. We work on the supposition of an established theory. And switch between deductive and inductive method, with an abductive method as a result. Theory: We work on the supposition of the latest theories from the authors of the balanced scorecard, Robert S. Kaplan and David P. Norton.

Parenting is increasingly seen as a profession which requires training and support with the purpose of creating improved interaction. A central question appears to be how the concept of interaction is defined. The aim of this study is to examine how training programs, trainers and parents perceive this concept, whether they define it the same way and whether trainers succeed in reaching parents with the message of what it actually is that will improve in the area of interaction. The study uses a phenomenological approach and a qualitative method.The research subject is the parental training program Komet, a manual-based education program for parents. The goal of the program is to offer families training in methods that have strong scientific support in order to reduce conflicts and to improve the relation and interaction between children and parents.One important result of the study is that parents and trainers viewed the concept of interaction from different perspectives.

In industries today the demand for reading the state of industrial equipment and thus prevent machine breakdown, is increasing. The company HMS Industrial Networks AB has a product on the market, Netbiter EC350 that is used to read sensors and thus find out the condition of industrial equipment. By reporting scanned data to users through a cloud service, users can keep track of their equipment. When developing Netbiter EC350 a slot was made for a Bluetooth module to offer clients a wireless reading in future developments. In this project a prototype was made to show how this Bluetooth communication can be implemented. The goal of the project was to create a Bluetooth communication between a Bluetooth sensor and Netbiter EC350. A user interface was made to allow the user to read sensor values. The result of the project shows how a Bluetooth communication can be implemented to read sensors wireless and therefore it fulfills its purpose and goal.

This thesis treats a new perspective in the theory of classification, the context-based approach. The aim is to find out what kind of value this new approach can have in the process of creating a classification scheme for a special library collection. The first question to be answered is how the context-based approach works in a real life. The second question investigates which role the research in this particular area might have. Illustrating a real-life situation, the unit of Rättsmedicinalverket in Linköping serves as the object of study.

This is a report of our examination project in electronics carried out for Bofors Test Center in Karlskoga. The task was to construct an electronic devise for starting up different kinds of measuring systems in exact time during test sequences. The modules that are used today are old and unreliable. Our goal was to construct a prototype, which later on is supposed to be developed into a useful system..

In speech and language intervention, the ability to interact is seldom evaluated; rather intervention is evaluated in terms of improved testresults.  If goal-setting in intervention also is based on everyday communicative needs, the relevance of the treatment may be increased and intervention outcome may be implemented in the patient?s natural environment.The present study, as part of a research-project, is based on analyses of interaction and interviews to examine everyday conversations and speech and language intervention. The aim was to explore if there is a relation between everyday communication needs and goal-setting in speech and language intervention for people with aphasia. A further aim was to investigate if there are everyday communicative needs that may form goals for speech and language intervention.Two individuals with aphasia and one individual with both dysarhtria and aphasia participated in the study. Three speech and language pathologists and two relatives also participated in the study.

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Proteins are vital to all cells in the body. They consist of long chains of amino acids. To be able to study the amino acid composition of a protein it is necessary to hydrolyse it, followed by separation and quantification. When the protein is hydrolysed, in this case ß-lactoglobulin, the protein is divided into individual amino acids. The method that traditionally has been used to hydrolyse proteins takes 24-72 hours to complete.
