  1. 1. Characteristics of Particulate Emissions from Low Temperature Combustion and Renewable Fuels : Aerosol Mass Spectrometry of Refractory Carbonaceous Particles

    Författare :Vilhelm Malmborg; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; Soot; BC; BrC; ROS; SP-AMS; MiniCAST; Diesel Engine; HVO; RME; Cook Stove; Emissions; Soot; BC; BrC; SP-AMS; ROS; MiniCAST; Diesel Engine; HVO; RME; Cook Stove;

    Sammanfattning : Particulate air pollution is one of the major causes of premature death in the world, and combustion-derived soot emissions contribute strongly to the particulate pollution to which humans are exposed. Black carbon (BC) is one such emission and denotes soot with strong light absorption in the ultraviolet to infrared spectrum. LÄS MER

  3. 2. NMR Studies of Gel-Emulsions; Diffusometry and Applications of Novel Field Gradient Techniques

    Författare :Carin Malmborg; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; modulated gradients; imaging; Physical chemistry; Fysikalisk kemi; NMR; emulsion; diffusion;

    Sammanfattning : The aim of these studies has been to investigate what information that can be obtained on gel-emulsions with nuclear magnetic resonance, NMR, as the investigating tool. The gel-emulsions are important in many technical applications such as in food products, in cosmetic and pharmaceutical formulations, and in emulsion explosives, just to name a few applications.

  4. 3. Catheter Ablation of Atrial Fibrillation and Atrial Flutter : A Comparison of Cryo and Radiofrequency Techniques

    Författare :Helena Malmborg; Carina Blomström-Lundqvist; Stefan Lönnerholm; Pekka Raatikainen; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Atrial fibrillation (AF) and atrial flutter (AFl) are two of the most common arrhythmias encountered in the population. Catheter ablation has emerged as a useful tool in the treatment of these arrhythmias. Although radiofrequency (RF) is the most commonly used energy source for ablation, cryoenergy may have some advantageous properties. LÄS MER

  5. 4. Analysis and Design of Hybrid Control Systems

    Författare :Jörgen Malmborg; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lyapunov theory; Mode switching; Multi-controllers; PID control; Simulation; Higher order sliding; Hybrid control; Sliding modes; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. LÄS MER

  7. 5. Numerical modeling of train-induced ground vibrations

    Författare :Jens Malmborg; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The population is growing, and an increasing proportion of the population live in urban areas. As a consequence, human exposure to noise and vibrations is increasing. Larger and denser cities lead to a higher amount of traffic close to where people work and live. LÄS MER
