1. 1. Partitioning and Control for Dynamical Systems Evolving on Manifolds

   Författare :Xiao Tan; Dimos V. Dimarogonas; James D. Biggs; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partitioning and control; Transition system; Geometric control; Barrier functions; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With the development and integration of cyber-physical and safety-critical systems, control systems are expected to achieve tasks that include logic rules, receptive decision-making, safety constraints, and so forth. For example, in a persistent surveillance application, an unmanned aerial vehicle might be required to "take photos of areas A and B infinitely often, always avoid unsafe region C, and return to the charging point when the battery level goes low.

   Sammanfattning : Autonomous systems have become increasingly prevalent in various industries, ranging from household cleaning robots to line inspection drones and copilot vehicles. Ensuring real-time safety is becoming a critical issue when the environment is rapidly changing. LÄS MER

4. 3. Topics in Modeling, Control, and Implementation in Automotive Systems

   Författare :Magnus Gäfvert; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; robotteknik; Automatiska system; control engineering;

   Sammanfattning : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. LÄS MER

5. 4. Regional studies of the optical, chemical and microphysical properties of atmospheric aerosols : Radiative impacts and cloud formation

   Författare :Admir Créso Targino; Douglas Nilsson; Radovan Krejci; Richard Leaitch; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric aerosols; particles; optical properties; cloud; ice crystals; chemical composition; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap;

   Sammanfattning : Atmospheric particles are ubiquitous in the Earth’s atmosphere and have potential to influence atmospheric chemistry, visibility, global climate and human health, particularly downwind from major pollution sources. The main objective of this thesis was to investigate questions pertaining to the microphysical, chemical and optical properties of aerosol particles by using in situ data collected during four experiments carried out in different regions of the Northern Hemisphere.
