Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

NANDA International, ett verktyg för evidensbaserad omvårdnadsdiagnostik : en studie om identifiering av omvårdnadsdiagnoser inom neurokirurgisk och thoraxkirurgisk omvårdnad

Studiens syfte var att undersöka hur klassificeringsverktyget NANDA International fungerade för att identifiera och belysa panoramat av omvårdnadsdiagnoser, på en neurokirurgisk och en thoraxkirurgisk vårdavdelning. NANDA International är ett evidensbaserat och standardiserat diagnosverktyg för omvårdnad. 40 patienter studerades jämnt fördelade på respektive vårdavdelning. Datainsamlingen följde sjuksköterskans gängse arbetsmetodik med patientbedömning enligt VIPS-modellen. Utifrån delmomenten dokumentationsgranskning, observation/bedömning och samtal, identifierades omvårdnadsdiagnoser.

Modellering av indunstning på Södra Cell Mönsterås

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Talas det tillräckligt om sex? : att upptäcka sexmissbruk inom beroende- och primärvården

Bakgrund: Trots ett ansvar att inbegripa patientens sexuella hälsa i till exempel ankomstsamtalet, känner många sjuksköterskor motvilja till detta. Vi har själva märkt att VIPS-sökordet sexualitet/reproduktion sällan används i vården och därför valde vi att genomföra denna studie. Syfte: Studiens syfte var att belysa hur sjuksköterskan uppmärksammar patientens sexuella beteende. Metod: Detta var en kvalitativ intervjustudie med fyra sjuksköterskor från beroende- och primärvården. Resultat: Fyra teman valdes ut; journalföring, sjuksköterskans samtal med patienten, samband mellan beroende/sjukdomar och sexualproblem samt behandling.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt

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.

Modellering av en panna med rörlig rost :  

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Adaptiv katalysatormodell för reglering

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

Analys, modellering och återskapande av fordonsdynamiska rörelser i tåg

The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.

Nytt busslinjenät i Luleå tätort: utveckling och utvärdering
av olika alternativ med datorstöd

Detta examensarbete behandlar framtidens busslinjenät i Luleå tätort, och har utförts på uppdrag av Luleå Lokaltrafik AB. Kommunfullmäktige i Luleå har i över 10 år önskat en utveckling och effektivisering av busstrafiken för att få fler att åka buss, både för att uppfylla kommunens miljömål och för att minska underskottet i Luleå Lokaltrafiks ekonomi. För närvarande täcks bara 43% av bolagets utgifter av biljettintäkter. Syftet med detta projekt var att förbättra ett konsultförslag till nytt linjenät från Trivector Traffic AB. Förslaget hade några problem, främst att driftskostnaderna skulle öka kraftigt, men också att tidtabellerna var för stressiga för förarna och att det skulle bli väldigt trångt på ett par linjer i morgonrusningen.

?Vad är det jag gör egentligen?? - om att med videons hjälp bli medveten om helheten

This project consists of an adaptation, trial and evaluation of a model for practicing. Based on prior research I created a model aiming mainly to raise a musician?s self- awareness around the different parameters a performance consists of. An additional wish was for it to simultaneously assist the musician in monitoring his or her progress. With video recording and self-evaluation as the two main parts I tried the model by using it over a period of three months.

Multipel regressionsanalys av variabler som paverkar BNP

In this report a model was constructed in order to determine how a number of covariates influence the gross domestic product, GDP. The covariates were chosen depending on their expected influence on GDP, for example education and life expectancy. The data used in this report are collected from the World Bank. The model to describe GDP has been calculated using multiple line arregression. In order to reach a reliable final model the number of covariates has been gradually decreased to eliminate insignificant covariates.

Hudiksvalls samordningsmodell- en modell för att underlätta samverkan?

AbstractHudiksvalls coordinating model - a model to make cooperation easierCamilla Andersson and Åsa GradinThe purpose of this study was to examine the experience each one of the administrators have of their own new model in Hudiksvall to make cooperation easier for the three different administrations in Hudiksvalls municipality. The study will focus on the administrators experiences of Hudiksvalls coordinating design. Questions of the study were: How is the influence of the model on the rules? How is the influence of the model on expectations and parts? What kind of influence did the model have on the responsibility distribution? What kind of influence has the model on the responsibilities at the transfer of costs? To answer the questions of the study we applied a qualitative method, it was made through a standardization interview guide and open questions, with six of the dealing officers who works with the model. Some of the results wich can be discern are by an economic character, andfor the clients that they won`t be passed around the administrations in the community, they get the right help, quick and safe.Key words: cooperation, coordination..

Simulering av filtrerade skärmfärger

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.

Modellering av rotationssystem

This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.
