Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

When a car owner want to lock or unlock his or her car today, it?s preferable done by using aremote control. The system is really comfortable when the car owner is using the remote.A problem arises if a thief gets the remote.The thief doesn?t have to know where the car is parked, an approximate estimation where thecar is parked is enough.For instance, it?s enough to know which car park the car is parked in. If the thief knows that,he/she can repeatedly activate the remote control while looking for a car indicating with lightsand sounds.Because of the fact that a car usually indicates that it has been unlocked by making a shortsound indication, there will be no problem finding the car.The purpose with this project is to make a prototype which makes it harder for a thief to findthe car.

The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart.

Different methods for shelterwood cutting have been used in differ-ent parts of Europe since the middle ages. The use of shelter wood cutting in Norway spruce (Picea abies (L.) Karst.) forests in Sweden met a revival in the early 1990s as an alternative for the dominating clear-cutting system when silvicultural costs increased dramatically for the latter. Shelterwood cutting systems involve some possible problems but also a lot of positive effects. Among the problems are increased risk of wind throw and damage of the remaining shelter trees caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity. This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden (62,4º N).

Delirium är ett vanligt tillstånd på intensivvårdsavdelningen (IVA) och forskning visar attpatienter som drabbas av delirium har högre mortalitet, längre vårdtider på sjukhus och sänktlivskvalitet lång tid efter vårdtiden. Det finns olika former av delirium: hyperaktivt,hypoaktivt och blandformer. Den vanligaste formen, hypoaktivt delirium, är lätt att feltolkasom översedering eller depression. Att använda sig av bedömningsinstrument kan göra attdelirium upptäcks tidigare och att patienten snabbare får adekvat vård, vilket kan lindraförloppet. Det har utvecklats olika instrument för att bedöma om patienterna har delirium.Syftet med denna studie var att undersöka om användandet av CAM-ICU (ConfusionAssessment Method for Intensive Care Unit - ett bedömningsinstrument av delirium) är ettanvändbart mätinstrument för sjuksköterskan att upptäcka delirium hos patienter som vårdaspå IVA.

Boliden Mineral Ab's mine in Garpenberg, Dalarna is going through a massiveexpansion. The annual ore production is being increased from 1,4 million tons to 2,5million tons in less than two years period of time. Along this expansion thedepartment of mining techniques is administrating a project of optimizing the shortterm planning for the mining production. Garpenberg have since mid 90s storedinformation from all mining processes in a database.The information consists of time data from all the different activities required in themining process, for example charging, blasting, loading etc. The database also containstime data of delays that are affecting the production.

The purpose of this study was to analyze the reconstruction in two short-documentaries by Arne Sucksdorff. The films are analyzed both in a stylistic and symbolical way..

Introduction: The complexity of the neonates? way of expressing pain is a difficulttask for the pediatric nurse. The Swedish national guidelines for prevention and treatmentof pain in the newborn infant is suggesting that departments regularly use structuredmethods, such as pain assessment instrument, for the assessment of pain in the neonatalperiod. Previous research shows that pain assessment instruments are only used in abouthalf of all pain assessments in Sweden. Neonate's cannot verbally communicate their pain,and are therefore dependent on the pediatric nurse to acknowledge the pain.

AbstractAt the UN Conference on Environment and Development in 1992 the nations stated that traditional environmental policies were not sufficient to handle the multidimensional challenges posed by sustainable development. Governments needed to broaden their political decision making procedures in order to coordinate and integrate environmental, social and economic policies. Therefore a new tool was introduced in Agenda 21, National Strategies for Sustainable Development (NSDS). The aim of an NSDS would be to bring together actors from all parts of society to jointly reach a consensus on how to work towards the vision of a sustainable society. An NSDS would be seen as a strategic tool to help focus national policies for SD.

This essay is an introduction to the intentions and purposes of the british play writer Sarah Kane (1971-1999). Her own voice is presented both via quotations linked to her work and by an explanation of her connections to the surrealist poet and actor Antonin Artaud. The main focus is on Kane?s second play, Phaedra?s Love, first performed in 1996. The play is analyzed in co-relation to La volonté de savoir, the first volume in Michel Foucault?s trilogy Histoire de la sexualité.

The purpose of this thesis was to internally examine the cooperation between different professions in municipal BoDa-units. By doing a qualitative study using focus-group-interviews in three municipalities, we were able to examine the personnel?s experience of cooperation issues and opportunities in BoDa-units.

The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.

The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.
