  2. 11. Visual filtering in box jellyfish: A simple system

    Author : Megan O'Connor; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tripedalia cystophora; box jellyfish; Cnidaria; Chiropsella bronzie; visual filtering; visual systems; microspectrophotometry; vision; eyes;

    Abstract : Unlike most jellyfish, box jellyfish (cubomedusae) are highly visually orientated. They are agile swimmers and use visual information to avoid obstacles and orientate themselves. READ MORE

  4. 12. Environmental filtering of bacteria in low productivity habitats

    Author : Inga Richert; Stefan Bertilsson; Annelie Wendeberg; Lise Øvreås; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacteria; environmental filtering; diversity; ecosystem service; hydrocarbon utilization; Southern Ocean; sediment; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Microbes fulfill important ecosystem functions by contributing as drivers of global nutrient cycles. Their distribution patterns are mainly controlled by environmental heterogeneities. So far, little is known about the mode of action of particular environmental drivers on the microbiota, particularly in low productivity habitats. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 14. Filter Bank Design for Subband Adaptive Filtering

    Author : Jan Mark de Haan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Filter Bank Design; Subband Adaptive Filtering;

    Abstract : Adaptive filtering is an important subject in the field of signal processing and has numerous applications in fields such as speech processing and communications. Examples in speech processing include speech enhancement, echo- and interference- cancellation, and speech coding. READ MORE

  7. 15. Particle Filtering and Optimal Control for Vehicles and Robots

    Author : Karl Berntorp; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle filtering; optimal control; automotive systems; out-of-sequence measurement; autonomy; model predictive control; sensor fusion; wheel slip; dynamic optimization;

    Abstract : This thesis covers areas within estimation and optimal control of vehicles, in particular four-wheeled vehicles. One topic is how to handle delayed and out-of-sequence measurements (OOSMs) in tracking systems. READ MORE
