  2. 1. SAR Studies of Capsazepinod Bronchodilators. The A-ring and the Coupling region

    Author : Maria Dalence; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; COPD; Asthma; Capsazepine; Bronchodilators; Organic chemistry; SAR studies; Organisk kemi;

    Abstract : Bronchoconstriction is a hallmark in respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). Current therapies use bronchodilating agents in order to control the exacerbations produced by limited airflow and improve the quality of life of patients suffering from these diseases. READ MORE

  4. 2. Design of Ultra-Low-Power Analog-to-Digital Converters

    Author : Dai Zhang; Atila Alvandpour; Trond Ytterdal; Linköpings universitet; []
    Keywords : analog-to-digital converter; ADC; successive approximation register; SAR; SAR ADC; ultra-low-power; power consumption bounds; medical implant devices;

    Abstract : Power consumption is one of the main design constraints in today’s integrated circuits. For systems powered by small non-rechargeable batteries over their entire lifetime, such as medical implant devices, ultra-low power consumption is paramount. READ MORE

  5. 3. Sea Surface Current Measurements Using Along-Track Interferometric SAR

    Author : Anis Elyouncha; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Synthetic aperture radar; Ocean remote sensing; SAR; Along-track InSAR; Sea surface currents;

    Abstract : Ocean currents affect the weather, the climate and the marine ecosystem. Observing ocean currents is important for understanding the upper-ocean layer dynamics and its interaction with the other components of the climate system. In-situ measurements are sparse and their deployment and maintenance is costly. READ MORE

  6. 4. Sea Ice and Ocean Environmental Applications of Spaceborn SAR

    Author : Sverre Thune Dokken; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radarsat; SSM I; ERS-1 2; ocean applications; sea ice applications; numerical models; SAR; Arctic Ocean; Envisat; climate change;

    Abstract : The worldwide focus on our changing environment has led to an increased need to observe and characterise a range of environmental phenomena. The Arctic Ocean is particularly sensitive to climate variations. READ MORE

  7. 5. Urban Land-cover Mapping with High-resolution Spaceborne SAR Data

    Author : Hongtao Hu; Yifang Ban; Johan Fransson; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; High-resolution; RADARSAT-1 SAR; RADARSAT-2 SAR; Urban Land Cover; Object-based Classification; Neural Network; Support Vector Machines.; Remote sensing; Fjärranalys;

    Abstract : Urban areas around the world are changing constantly and therefore it is necessary to update urban land cover maps regularly. Remote sensing techniques have been used to monitor changes and update land-use/land-cover information in urban areas for decades. Optical imaging systems have received most of the attention in urban studies. READ MORE
