  2. 1. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Author : Diana Yamalova; Alexander Medvedev; Xiaoming Hu; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. READ MORE

  4. 2. On Identification of Biological Systems

    Author : Egi Hidayat; Alexander Medvedev; Peter Stoica; Elling Jacobsen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; biomedical systems; insect vision; endocrine systems; orthogonal basis functions; time delay; impulse response; Laguerre functions; Laguerre polynomials; excitation design; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : System identification finds nowadays application in various areas of biological research as a tool of empiric mathematical modeling and model individualization. A fundamental challenge of system identification in biology awaits in the form of response variability. READ MORE

    Abstract : The amount of biomedical information that is disseminated over the Web increases every day. This rich resource is used to find solutions to challenges across the life sciences. READ MORE

  6. 4. Towards Heart Rate Variability Tools in P-Health : Pervasive, Preventive, Predictive and Personalized

    Author : Farhad Abtahi; Kaj Lindecrantz; Birgitta Janerot Sjöberg; Fernando Seoane; Annette Bruchfeld; Metin Akay; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heart Rate Variability; Cholinergic Anti-inflammatory Pathway; Autonomic Nervous System; Vagal activity; Biofeedback; Gamification; Serious Gaming; Inflammatory Markers; Raspberry PI; Medical Technology; Medicinsk teknologi;

    Abstract : Heart rate variability (HRV) has received much attention lately. It has been shown that HRV can be used to monitor the autonomic nervous system and to detect autonomic dysfunction, especially vagal dysfunction. Reduced HRV is associated with several diseases and has also been suggested as a predictor of poor outcomes and sudden cardiac death. READ MORE

  7. 5. The Physical Axon : Modeling, Simulation and Electrode Evaluation

    Author : Malcolm Latorre; Karin Wårdell; Göran Salerud; Ulrich Hofmann; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electrodes are used in medicine for detection of biological signals and for stimulating tissue, e.g. in deep brain stimulation (DBS). For both applications, an understanding of the functioning of the electrode, and its interface and interaction with the target tissue involved is necessary. READ MORE
