  1. 1. Respiratory inductive plethysmography (RIP) : calibration, breathing pattern analysis and external CO2 dead space measurement

    Författare :Tomas Strömberg; Gert Nilsson; Per M. Gustafsson; Steffen Groth; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Respiratory inductive plethysmography (RIP) is an important tool for ventilatory monitoring in research studies because it has minimal influence on the spontaneous breathing pattern and because the rib cage and abdominal contributions to the breaths are measured. RIP measures changes in rib cage and abdominal cross-sectional areas which are translated into lung volume estimates via RIP calibration against e. LÄS MER

  3. 2. Quantitative image analysis : a focus on automated characterization of structures in optical microscopy of iron ore pellets

    Författare :Frida Nellros; Carolina Wählby; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : Sintering occurs in many types of material such as iron, ceramics and snow, typically during thermal treatment, and aects the material properties, particularly the strength, by the bonding of particles into a coherent structure. In order to improve the mechanical strength in magnetite iron ore pellets it is important to be able to characterize and quantitatively measure the degree of sintering and features that impact the process of sintering.

  4. 3. Cooperative Compressive Sampling

    Författare :Ahmed Zaki; Lars Kildehøj; Saikat Chatterjee; Jan Østergaard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressive sampling; greedy algorithms; convex optimisation; RIP analysis; fusion strategy; distributed learning; sparse learning; stochastic matrix; consensus; sparse estimation; Telecommunication; Telekommunikation;

    Sammanfattning : Compressed Sampling (CS) is a promising technique capable of acquiring and processing data of large sizes efficiently. The CS technique exploits the inherent sparsity present in most real-world signals to achieve this feat. Most real-world signals, for example, sound, image, physical phenomenon etc., are compressible or sparse in nature. LÄS MER

  5. 4. Expression and novel function of CD43 in colon cancer cells

    Författare :Christian X Andersson; Göteborgs universitet; []
    Nyckelord :CD43; leukosialin; sialophorin; mucin; nuclear localization; nuclear signaling; Wnt-signaling; beta-catenin; regulated intramembrane cleavage; RIP; proteolytic cleavage;

    Sammanfattning : CD43 is a transmembrane protein containing an extracellular domain that is extensively O-glycosylated, and a relatively large intracellular domain with a conserved sequence between human, rat and mouse. It is frequently expressed in haematopoietic cell lines where it functions as a regulator of cell adhesiveness, a signal transducer and a cytoskeleton-interacting protein. LÄS MER

  7. 5. Paediatric sleep-disordered breathing - diagnostics and treatment

    Författare :Gunnhildur Gudnadottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sleep-disordered breathing; Children; Tonsillectomy; Tonsillotomy; Absenteeism; Intranasal steroid treatment; Respiratory polygraphy; RIP flow;

    Sammanfattning : Sleep-disordered breathing (SDB) in children causes multiple health problems and diminished quality of life. It is usually caused by tonsil and adenoid hypertrophy and is traditionally treated with adenotonsillar surgery. LÄS MER
