  2. 1. Modeling Analog to Digital Converters at Radio Frequency

    Author : Niclas Björsell; Peter Händel; Niclas Keskitalo; Linus Michaeli; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ADC; Analog to Digital Converters; Signal processing; Telecommunication; Telekommunikation; Electronics;

    Abstract : Det här arbetet handlar om att ta fram beteendemodeller av analog till digital omvandlare avsedda för tillämpningar i radiofrekvensområdet. Det gäller tillämpningar inom telekommunikation men även in test- och mätinstrument där omvandlingen från analoga till digitala signaler ofta är en prestandamässig flaskhals. READ MORE

  4. 2. The Robustness and Energy Evaluation of a Linear Quadratic Regulator for a Rehabilitation Hip Exoskeleton

    Author : Rabé Andersson; Niclas Björsell; Daniel Rönnow; Gianni Borghesan; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip Rehabilitation Exoskeleton; Robust Controller; Energy Consumption; Series Elastic Actuator SEA ; LQR Control; Luenberger State Observer; Torque Control; Höftexoskelett för rehabilitering; Robust reglering; Energiförbrukning; serieelastiskt manöverdon SEA ; LQR reglering; Luenberger State Obser-ver; Moment reglering;

    Abstract : The implications of gait disorder, muscle weakness, and spinal cord injuries for work and age-related mobility degradation have increased the need for rehabilitation exoskeletons. Specifically, the hip rehabilitation exoskeletons due to a high percentage of the mechanical power is generated by this join during the gait cycle. READ MORE
