  1. 1. Software tools for matrix canonical computations and web-based software library environments

    Författare :Pedher Johansson; Bo Kågström; Erik. Elmroth; Alan Edelman; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Canonical structure; Jordan canonical form; controllability; StratiGraph; Matlab toolbox; Kronecker canonical form; matrix; matrix pencil; perturbation theory; closure hirerarchy; matrix stratification; control system; observability; Numerical analysis; Numerisk analys;

    Sammanfattning : This dissertation addresses the development and use of novel software tools and environments for the computation and visualization of canonical information as well as stratification hierarchies for matrices and matrix pencils. The simplest standard shape to which a matrix pencil with a given set of eigenvalues can be reduced is called the Kronecker canonical form (KCF). LÄS MER

  2. 2. Design and optimization of parallel haptic devices : Design methodology and experimental evaluation

    Författare :Suleman Khan; Kjell Andersson; Jan Wikander; Ölvander Johan; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical simulation; 6-DOF haptic devices; design methodology.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : The simulation of surgical procedures, in the case of hard tissues such as bone or teeth milling, using a haptic milling surgery simulator requires a haptic device which can provide high stiffness and transparency. To mimic a real milling process of hard tissue, such as for example creating a narrow channel or cavity, the simulator needs to provide force/torque feedback in 5–6 degrees of freedom (DOF). LÄS MER

  3. 3. On the Fundamentals of the Engineering Design Process

    Författare :Damien Motte; Produktutveckling; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; systems theory; design theory; engineering design; product development; problem solving; creativity; machine design; maskinkonstruktion;

    Sammanfattning : In an industrial context when the product development cycles are shortened and constraints on technical innovations are high, it is very important to provide a very efficient and effective engineering design activity. In the current engineering design literature, most methodologies are by and large based on the so-called systematic engineering design approach. LÄS MER

  4. 4. Applying Design Analytics to Understand Engineering Change Request Information

    Författare :Ívar Örn Arnarsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Design Structure Matrix; Design Analytics; Engineering Change Request; Markov chain.; Product Development;

    Sammanfattning : Large complex system development projects take several years to carry out. Such projects involve hundreds of engineers who develop tens of thousands of parts and millions of lines of code. During the course of a project, many design decisions often need to be changed due to the emergence of new information. LÄS MER

  5. 5. Ceria Nanoparticle Hybrid Materials : Interfacial Design and Structure Control

    Författare :Eric Johansson Salazar-Sandoval; Mats Johansson; Wolfgang Bremser; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This doctoral thesis addresses the challenge of bringing two very different materials into intimate chemical contact: inorganic metal oxide nanoparticles and acrylic polymers. In order to achieve this ambitious goal, the work has been divided into a series of more accessible tasks. LÄS MER
