  1. 6. White Layer Formation during Hard Turning of Through-Hardened Martensitic and Bainitic AISI 52100 Steel

    Författare :Seyed Hosseini; Chalmers University of Technology; []
    Nyckelord :white layers; residual stresses; phase transformation; dynamic recovery; bainite; dynamic recrystallization; carbide deformation; retained austenite; steel; martensite;

    Sammanfattning : Increased demands for flexible manufacturing lines, shorter cycle times and reduced impact on the environment drives the need for optimization of today’s manufacturing. For machining of hardened steel parts (>45 HRC), grinding has been the obvious choice for many decades. However, hard turning has often been considered as a replacement due to e. LÄS MER

  2. 7. Development of a Whole Body Atlas for Radiation Therapy Planning and Treatment Optimization

    Författare :Sharif Qatarneh; Anders Brahme; Bengt Lind; Anders Ahnesjö; Stockholms universitet; []
    Nyckelord :3D whole body atlas; lymph node topography; matching transformation; radiation therapy planning; radiobiological optimization; segmentation; target volume definition; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : The main objective of radiation therapy is to obtain the highest possible probability of tumor cure while minimizing adverse reactions in healthy tissues. A crucial step in the treatment process is to determine the location and extent of the primary tumor and its loco regional lymphatic spread in relation to adjacent radiosensitive anatomical structures and organs at risk.

  3. 8. Geographical Information Technologies – Decision Support for Road Maintenance in Uganda

    Författare :Lydia Mazzi Kayondo-Ndandiko; Blekinge Tekniska Högskola; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Data Model; Dynamic Segmentation; Geographical Information Technologies GITs ; Geographical Information Systems for Transportation GIS-T ; Linear referencing; Methodological Framework; Research and Development; Road maintenance; Road Infrastructure Maintenance RIM ; Science Technology and Innovation; Spatial Data Infrastructure; Uganda;

    Sammanfattning : This study set out to develop a framework within which the use of Geographical Information Technologies (GITs) can be enhanced in Road Infrastructure Maintenance (RIM) in Uganda. Specifically it was guided by 3 objectives; 1. To assess the gaps in the use of GITs for RIM in Uganda and the limitations to accessing these technologies, 2. LÄS MER

  4. 9. Ultrasound Image Analysis for Automated Classification of Atherosclerotic Plaque in the Human Carotid Artery

    Författare :Peter Holdfeldt; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification; dynamic programming; carotid artery; Java program; image segmentation; ultrasound images; intima-media thickness; atherosclerotic plaque;

    Sammanfattning : Cardiovascular diseases, caused by atherosclerosis, is one of the most common causes of death in the industrialized world. Two risk factors, that both can be assessed with ultrasound, are the Intima-Media Thickness (IMT) in the arterial wall and the composition of the atherosclerotic plaque. LÄS MER

  5. 10. Segmentation and tracking of cells and particles in time-lapse microscopy

    Författare :Klas E. G. Magnusson; Joakim Jaldén; Dirk Padfield; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cell tracking; Particle tracking; Multiple target tracking; Image segmentation; Image processing; Computer vision; Open source software; Time-lapse microscopy; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In biology, many different kinds of microscopy are used to study cells. There are many different kinds of transmission microscopy, where light is passed through the cells, that can be used without staining or other treatments that can harm the cells. LÄS MER
