Den här rapporten beskriver arbetet med en automatiserad provrörsförflyttare. Det är ett examensarbete som har gjorts på företaget Q-linea AB. En karuselliknande konstruktion med en stegmotor användes för att flytta prover mellan ett antal positioner. En mikrokontroller som hanterar styrning och sensordata har programmerats i C. LabVIEW och en USB-kamera har använts som hjälp till att göra utvärderingar och tester av systemet.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

Sulforafan är en isothiocyanat-förening som finns i stora mängder i olika kålväxter. Sulforafan har setts ha en kemopreventiv inverkan bland annat genom att inducera fas II-enzymer styrda av transkriptionsfaktorn nuclear factor E2-related factor-2 (Nrf2). Nrf2 är mycket viktig i cellers skydd mor oxidativ- och elektrofil stress och inducerar uttrycket av många olika gener, bland annat olika tranportproteiner. Breast cancer resistance protein (BCRP) är en av transportörerna som tros induceras av Nrf2. BCRP finns i stora mängder i lakterande juvervävnad men också i många andra vävnader där den transporterar läkemedel ut ur cellerna.

This paper discusses runic inscriptions from the middle ages on Gotland and how they portray social structure. It focuses on three themes: (1) fixed time and space, (2) women and the nuclear family and (3) profession and social status/structure. It also discusses changes brought on by a more structured and established Christianity, as well as differences between medieval rune stones on Gotland and their predecessors Viking Age rune stones in the Mälar Valley..

This thesis has been made on behalf of Forsmarks Kraftgrupp AB and is the final part of the education of Bachelor of Engineering in ? Innovation, production and logistics atMälardalens Högskola.Forsmark nuclear power plant is located in Östhammars municipality at the coast of Uppland. The three nuclear reactors in Forsmark together produces approximately one-sixth of Sweden?s electricity consumption each year.The background of this study is that a large number of requests come to the purchasing department with incomplete information. Usually it is in the description of what is to be acquired as the information is incomplete, but also in knowing when Quality Control-functions (QC) is supposed to be used.The aim of this work is to describe and analyse the material acquisition process.

The purpose of this paper is to see how differences are handled in preschools, with a focus on children with homo- or bisexual parents. By doing this we wanted to see how the conditions for a child with homo- or bisexual parents looks like, in order to have their family conditions mirrored, confirmed and visualised in the preschool.The foundation for the discussion is a questionaire which has been answered by 229 preschool workers from 24 different preschools in the City of Stockholm. The result of the questionaire has been handled in a statistics program. Our analysis is based on the statistical numbers and the written replies to the open questions in the questionaire.As a theoretical starting point we have used Iris Marion Young?s ideas about how our society is coloured by an ideal of similarity that defines liberation as the transcendence of group difference, where the dominant group cannot see how their perspective is just one of several perspectives.

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

Kärnkraftsfrågan har sedan åttiotalet varit omdebatterad i Sverige och under 2011 harfrågan blivit högaktuell efter kärnkraftsolyckan i Fukushima. Eftersomdemokratibegreppet utgör grunden i den svenska skolan är det relevant att ifrågasättahur olika former av kärnkraftsundervisning står i relation till demokratiuppdraget. Syftetmed studien var att undersöka hur ett antal lärare beskriver sin kärnkraftsundervisning iförhållande till demokratiuppdraget, därutöver att konstruera ett rollspel om kärnkraftutifrån lärarnas tankar och demokratiuppdraget. Första delen av studien bygger påintervjuer med högstadielärare i de naturorienterade ämnena. Respondenterna fickbeskriva sin kärnkraftsundervisning, vilken sedan utvärderades i förhållande till skolansdemokratiuppdrag.

Title: Every second week. A study on how co-parented children do family. The aim of the study is to explore children?s day-to-day experiences of co-parenting. It focuses on how the children actively participate in the process of shaping family life and their own childhoods in the context of family change.

Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.

Hospitals have a set perception as an unpleasant and frighteningatmosphere.The examination-rooms of today within the children?shospitals are often bare and needs embellishment and decoration tocreate a satisfying setting. The decoration might have the function asa divertion from pain and anxiety.According to my experience the decorations of today consists mainlyof Winnie the Pooh figures, a clown or a hockey poster, never anythinglinked to the body and it?s functions.Spina, Thorax & Femur is a project that focuses on the visual identityand possibility to a deeper understanding and playfulness around thebody perception within the nursing environment.A visit at the hospital could be part of a creative knowledgeacquisition. The project result are two boards of glass-enamelledsteel.

Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

Small hydropower plants have been an important source for electricity for many years. During the 70?s the general thought was that nuclear was the future. Around 2000 small waterpower plants were shut down. It wasn?t profitable to invest in.
