Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen. Modellen beskriver hur vattenflöde och turbinmoment påverkas av …

… the analysis, are the competences for handling communication, algorithms, and modeling. Some ”hidden” mathematics were observed and that will also be discussed. Perhaps in the future math will be performed by computer programs only?
… lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other …
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 …
By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted …
This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to …
… Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process. The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed …
… electrical market and optimization. An essential part of the work consists of modeling of hydropower systems and two different models are accomplished. Both models include delay time and maximum discharge changes among other things. The first model is a mixed integer linear …
Fördjupad analys och modellering av tjänsteprocesser bserad på tjänsteforskning,systemvetenskap och statisktisk processkontroll( SPC).
… tre viktiga gränssnitt: encounter-, support- och teknikgränssnitten. Unified Modeling Language, UML och vissa delar av teori och metodik inom statistisk processkontroll, SPC samt Six Sigma konceptet presenteras och tillämpas på processkartläggning och analys av tid och …
… analysis methods for chlorinated solvents are described. Planning, fieldwork, modeling and risk analysis are described. Projects concerning chlorinated solvents completed by Golder Associates AB have been compiled and analysed. Based on the compilation, conclusions have been …
detaljeringsgradens betydelse för läsbarheten hos digitala tredimensionella landskapsmodeller
… experience the model as a landscape become clear. I choose to concentrate my modeling on the terrain; I created two models with differing resolution: one model created from points with 0.05 meters resolution and one model created from contour lines at 1meter intervals. During my …

… the components in the fuel library handle a two phase flow of fuel and air. Modeling a two phase flow is not trivial and discontinuous mass flow and pressure values are also implemented and discussed.
… initial imperfections and that the most severe buckling mode was used in the modeling of the imperfections. The handcalculation model was developed to imitate the one for patch loading in EN 1993-1- 5 (EC3), because it may then work as an addition to EC3. The model was developed …
Med detta examensarbete vill vi belysa problematiken runt tredimensionell fastighetsbildning. Som objekt har vi använt oss av ett bergrum på Liljeholmskajen i Stockholm.
… using Modelica, which is an object oriented language specifically designed for modeling large systems governed by differential algebraic equations. The skewing of the arms is based on keeping a characteristic angle of the structure. In this way the stiffness of the robot is …
