  1. 41. Energy Efficient Longitudinal Control

    Författare :Rickard Arvidsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Vehicles; Optimal Control; Hybrid drivetrain control; Combustion Engines;

    Sammanfattning : Vehicles are contributing to global and local environmental problems as a result of fossil fuels. A majority of the combustion engine population is driven by fossil fuels and electrified vehicles are also to a large extent dependent on electricity production from fossil fuels. LÄS MER

  3. 42. Probes, pronouns and binding in the Minimalist Program

    Författare :Fredrik Heinat; Engelska; []
    Nyckelord :HUMANIORA; HUMANITIES; Grammar; probes; agree; pronouns; distributed morphology; syntax; minimalims; semantics; semiotics; Grammatik; semantik; semiotik;

    Sammanfattning : In chapter 2, I claim that not only heads, but phrases, too, are probes. I show that there are in fact no theoretical and empirical problems involved if we abandon the stipulation that only heads may probe. In chapter 3, I explore the structure of nominal expressions. LÄS MER

  4. 43. Submicrometre aerosol emissions from sea spray and road traffic

    Författare :Monica Mårtensson; Douglas Nilsson; Christer Johansson; Michael Smith; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Eddy covariance method; aerosol emissions; submicrometre sea salt parameterisation; primary marine organic aerosols; sea spray; road traffic emission factors; air-sea exchange; aerosol dynamics model; internal aerosol mixing; combustion aerosols; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The uncertainty of the climate and health effects of aerosols is still large, one important reason being lack of knowledge of the primary emissions. This thesis combines laboratory and field experiments, and process modelling in an effort to better quantify the submicrometre aerosol emissions and to understand some of the processes in the atmosphere.

  5. 44. Distribution Preserving Quantization

    Författare :Minyue Li; W. Bastiaan Kleijn; Jan Østergaard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : In the lossy coding of perceptually relevant signals, such as sound and images, the ultimate goal is to achieve good perceived quality of the reconstructed signal, under a constraint on the bit-rate. Conventional methodologies focus either on a rate-distortion optimization or on the preservation of signal features. LÄS MER

  7. 45. Solubility of HFC Refrigerants in Long-Chained Hydrocarbons and Pentaerythritol Esters Measurements and Development of Predictive Models

    Författare :Åsa Wahlström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Restrictions for environmental reasons on the use of CFCs and HCFCs, the traditional working fluids in heat pumps, refrigeration plants and air conditioning, have led to the use of pure HFCs and blends of HFCs. However, since HFCs have a different influence on compressor oils, new oils that are compatible with HFCs need to be found. LÄS MER
