  2. 1. Model Based Coding : Initialization, Parameter Extraction and Evaluation

    Author : Zhengrong Yao; Haibo Li; Ralf Schäfer; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Model-based coding; Motion estimation; Vision based tracking; Initialization; Analysis-by-Synthesis; Texture mapping; Active tracking.; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

    Abstract : This thesis covers topics relevant to model-based coding. Model-based coding is a promising very low bit rate video coding technique. The idea behind this technique is to parameterize a talking head and to extract and transmit the parameters describing facial movements. At the receiver, the parameters are used to reconstruct the talking head. READ MORE

  4. 2. Model-based Approaches to Privacy Compliance

    Author : Hanaa Alshareef; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; GDPR; purpose limitation; social networks; refinement; privacy by design; data flow diagram; collaborative access control;

    Abstract : In the last decade, information technologies have been developing dramatically, and therefore data harvested via the Internet is growing rapidly. This technological change has a negative impact on privacy due to the sensitivity of the data collected and shared without convenient control or monitoring. READ MORE

  5. 3. An Integrated Approach towards Model-Based Mechatronic Design

    Author : Ahsan Qamar; Jan Wikander; Hans Vangheluwe; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mechatronics; mechatronic design; development process; conceptual design; model-based systems engineering MBSE ; model integration; SysML; model-driven engineering; consistency; Industrial engineering and economy; Industriell teknik och ekonomi; Software engineering; Programvaruteknik; Systems engineering; Systemteknik;

    Abstract : Mechatronic design is an enigma. On the one hand, mechatronic products promise enhanced functionality, and better performance at reduced cost. On the other hand, optimizing mechatronic design concepts is a major challenge to overcome during the design process. READ MORE

  6. 4. Model Based Fault Diagnosis : Methods, Theory, and Automotive Engine Applications

    Author : Mattias Nyberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Model based fault diagnosis is to perform fault diagnosis by means of models. An important question is how to use the models to construct a diagnosis system. To develop a general theory for this, useful in real applications, is the topic of the first part of this thesis. READ MORE

  7. 5. Model Based Optimization of a Complete Diesel Engine/SCR System

    Author : Claes Ericson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MPC; model based optimization; real time models; model based control; SCR; optimization; EGR;

    Abstract : Achieving upcoming emissions legislation (Euro VI) for heavy trucks is a serious challenge for the manufacturers. Apart from the increasingly strict limits on nitrogen oxides (NOx) and particulate emissions (PM), the limited amount of fossil fuels as well as alarming climate changes simultaneously drives the demand for low CO2 emissions.
