  1. 1. PDEModelica – A High-Level Language for Modeling with Partial Differential Equations

    University dissertation from Institutionen för datavetenskap

    Author : Levon Saldamli; Peter Fritzson; Bernhard Bachmann; Francesco di Casella; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; PDEModelica; Modelica; object-oriented modeling; equation-based modeling; declarative modeling; high-level modeling languages; mathematical modeling languages; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : This thesis describes work on a new high-level mathematical modeling language and framework called PDEModelica for modeling with partial differential equations. It is an extension to the current Modelica modeling language for object-oriented, equation-based modeling based on differential and algebraic equations. READ MORE

  2. 2. Sea Level Compensation System for Wave Energy Converters

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Valeria Castellucci; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ocean energy; Tides; Linear generator; Point absorber; Offshore experiment; Hydro-mechanic modeling; Power absorption; Control system; Communication system; Measurement system; Lysekil research site; Wave Hub.;

    Abstract : The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. READ MORE

  3. 3. On aircraft fuel system design : concept evaluation and system modeling

    University dissertation from Linköping : Linköpings universitet

    Author : Hampus Gavel; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : THE LARGEST AND most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. READ MORE

  4. 4. The Core of Aerial Robotic Workers Generalized Modeling, Estimation, and Control

    University dissertation from Luleå : Luleå University of Technology

    Author : Emil Fresk; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial robotics; generalized modeling; generalized estimation; generalized control; Reglerteknik; Control Engineering;

    Abstract : In this thesis we are going to explore what the operational core, both mathematically and algorithmically, of an Aerial Robotic Worker consists of, in order to estimate its egomotion and parameters, and adaptively control the aerial vehicle. Moreover, the aim of this thesis is to be a condensed reference for the corresponding areas of aerial robotics, in order to provide a stable and complete foundation on which one can continue research on.

  5. 5. Understanding Multicore Performance Efficient Memory System Modeling and Simulation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andreas Sandberg; Uppsala universitet.; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; Simulation; Modeling; Sampling; Caches; Memory Systems; gem5; Parallel Simulation; Virtualization; Sampling; Multicore; Datavetenskap; Computer Science;

    Abstract : To increase performance, modern processors employ complex techniques such as out-of-order pipelines and deep cache hierarchies. While the increasing complexity has paid off in performance, it has become harder to accurately predict the effects of hardware/software optimizations in such systems. READ MORE
