    Sammanfattning : Heterobasidion annosum sensu lato (s.l.) species are destructive pathogens causing root and butt rot in conifers. The species complex consists of five species: H. LÄS MER

  3. 2. Silicon Nanowire Based Electronic Devices for Sensing Applications

    Författare :Qitao Hu; Zhen Zhang; Shi-Li Zhang; Si Chen; Jeehwan Kim; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon nanowire; field-effect transistor; nanoelectromechanical resonator; CMOS-compatible; multiplexed detection; single charge detection; quantum sensing; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : Silicon nanowire (SiNW) based electronic devices fabricated with a complementary metal-oxide-semiconductor (CMOS) compatible process have wide-range and promising applications in sensing area. These SiNW sensors own high sensitivity, low-cost mass production possibility, and high integration density. LÄS MER

  4. 3. Apoptotic and necrotic cell death after photothrombotic ring stroke : characterization of a stroke model and its morphological and molecular consequences

    Författare :Xiao-Lei Hu; Per Wester; Klas Blomgren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cerebral ischemic cell death is a major cause of disability and death among stroke patients. The brain cell demise can occur through apoptosis or necrosis or as a continuum of both. This study aimed at establishing a dual setup of a photothrombotic ring stroke model and exploring its morphological and molecular consequences. LÄS MER

  5. 4. Self-organization and Intervention of Nonlinear Multi-agent Systems

    Författare :Yuecheng Yang; Xiaoming Hu; Torkel Glad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent system; linear system; nonlinear system; opinion dynamics; crowd dynamics; leader-follower based model; optimal control; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : This dissertation concerns the self-organization behaviors in different types of multi-agent systems, and possible ways to apply interventions on top ofthat to achieve certain goals. A bounded confidence opinion dynamics modelis considered for the first two papers. LÄS MER

  7. 5. Data Filtering and Control Design for Mobile Robots

    Författare :Maja Karasalo; Xiaoming Hu; John Baras; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; formation control; tracking; nonlinear control; optimal smoothing; adaptive filtering; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : In this thesis, we consider problems connected to navigation and tracking for autonomousrobots under the assumption of constraints on sensors and kinematics. We study formation controlas well as techniques for filtering and smoothing of noise contaminated input. The scientific contributions of the thesis comprise five papers. LÄS MER
