  2. 21. Rummet och människans rörelser

    Author : Inger Bergström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; utility of space; modern city concept; everyday social life; urban public space; form and motion; experience of room;

    Abstract : This book deals with objects and design of spatial elements and how they affect the motions of humans, their significance for the use of space as well as events in human life. As a framework, problems of perceptual research is dealt with and the possibilities to making general and valid notions on phenomena that occur from subjective experiences. READ MORE

  4. 22. Nuclear fission and fusion in a random-walk model

    Author : Martin Albertsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fission; Brownian shape motion; energy partition; neutron multiplicity; kinetic energy; fusion; superheavy elements; quasifission; Fysicumarkivet A:2021:Albertsson;

    Abstract : This dissertation deals with theoretical descriptions of nuclear fission and synthesis of superheavy elements via fusion. The associated shape evolutions are treated using a random-walk approach where both the potential energy and the nuclear level density influence the dynamics. READ MORE

  5. 23. Volunteer Kinematics and Muscle Activity in Dynamic Events Representative of Pre-crash Scenarios, Evaluation Data for Human Body Models

    Author : Ghazaleh Ghaffari; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; volunteer; evasive manoeuvres; human body model; validation data; occupant kinematics; pre‐pretensioner belt; lane change; boundary conditions;

    Abstract : Advanced integrated safety technologies in modern cars such as collision avoidance intervention and pre-crash activated restraint systems involve comprehensive research on how vehicle occupants respond to these systems in pre-crash situations. Human Body Models (HBMs) are mathematical tools developed to predict human responses and injury outcomes in different pre-crash and in-crash situations. READ MORE

  6. 24. Discrete Scale-Space Theory and the Scale-Space Primal Sketch

    Author : Tony Lindeberg; Jan-Olof Eklundh; Jan. J Koenderink; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer vision; low-level processing; scale-space; diffusion; Gaussian filtering; discrete smoothing; primal sketch; segmentation; descriptive elements; scale detection; image structure; focus-of-attention; tuning low-level processing; blob detection; edge detection; edge focusing; histogram analysis; junction classification; perceptual grouping; texture analysis; critical points; classification of blob events; bifurcations; drift velocity; density of local extrema; multi-scale representation; digital signal processing; Computer Science; Datalogi;

    Abstract : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. READ MORE

  7. 25. Transient vibrations from dry clutch operation in heavy-duty truck powertrains : Modelling, simulation and validation

    Author : Jakob Sjöstrand; Leif Kari; Ines Lopez Arteaga; Per Erik Austrell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dry clutch system; Engagement; Disengagement; Dry-friction; LuGre friction model; Heavy-truck powertrain; Teknisk mekanik; Engineering Mechanics;

    Abstract : For internal combustion engines used in heavy-duty vehicles, increased engine efficiency and consequently reduced CO2 emissions can be obtained if the engine speed can be kept within an optimal speed range. This requires swift and frequent gear shifts where the dry friction clutch is utilized. READ MORE
