  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. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Author : Diana Yamalova; Alexander Medvedev; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : This licentiate thesis deals with a special class of hybrid systems, where the continuous linear part is controlled by an intrinsic impulsive feedback that contributes discrete dynamics. The impacting pulsatile feedback signal is not available for measurement and, therefore, has to be reconstructed. READ MORE

  5. 3. Passive Acoustic Monitoring of Moving Targets by Sparse Underwater Sensor Network

    Author : Viktoria Zetterberg; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Surveillance of sound activities in the sea is of great importance for many applications. A common way to monitor the sea is to register sound with the help of a group of closely placed sensors that form a one-dimensional or two-dimensional array. READ MORE

  6. 4. Advancement of atmospheric research tools

    Author : Gustav Stenberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : This thesis describes contributions made to improve atmospheric research tools through implementation of modern technologies on existing instruments. The dynamic changes in the atmosphere are ever more evident and the need to monitor them have risen in recent years. READ MORE

  7. 5. Conduction Disturbances in Patients with Atrial Fibrillation

    Author : Eva Hertervig; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Pulmonary Vein Potentials; Atrial Fibrillation; Conduction Disturbances;

    Abstract : Background: The electrophysiological mechanisms underlying atrial fibrillation (AF) are incompletely understood. Experimental studies have shown that remodelling of the atrial myocardium is linked to the occurrence and perpetuation of AF. READ MORE
