  1. 1. On-chip Ultrasonic Sample Preparation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Ida Sadat Iranmanesh; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ultrasound; Sample preparation; Particle manipulation; Physics; Fysik; Biologisk fysik; Biological Physics;

    Abstract : Acoustofluidics has become a well-established technology in the lab-on-a-chip scientific community. The technology involves primarily the manipulation of fluids and/or particles in microfluidic systems. READ MORE

  2. 2. Comparative network analysis of human cancer: sparse graphical models with modular constraints and sample size correction

    University dissertation from Göteborg : Chalmers University of Technology

    Author : José Sánchez; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Inverse covariance matrix; precision matrix; graphical models; high-dimension; low-sample; networks; sparsity; fused lasso; elastic net; cancer.;

    Abstract : In the study of transcriptional data for different groups (e.g. cancer types) it's reasonable to assume that some dependencies between genes on a transcriptional or genetic variants level are common across groups. Also, that this property is preserved locally, thus defining a modular structure in the model networks. READ MORE

  3. 3. Efficient strategies for collecting posture data using observation and direct measurement

    University dissertation from Umeå : Umeå universitet

    Author : Per Liv; Högskolan i Gävle.; Högskolan i Gävle.; Umeå universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational and Environmental Medicine; arbets- och miljömedicin; Exposure assessment; arm elevation; exposure variability; variance components; random effects model; precision; bias; sample size; sample allocation; calibration; bootstrapping;

    Abstract : Relationships between occupational physical exposures and risks of contracting musculoskeletal disorders are still not well understood; exposure-response relationships are scarce in the musculoskeletal epidemiology literature, and many epidemiological studies, including intervention studies, fail to reach conclusive results. Insufficient exposure assessment has been pointed out as a possible explanation for this deficiency. READ MORE

  4. 4. Microfluidic bases sample preparation for blood stream infections

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Sahar Ardabili; KTH.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sample-preparation; microfluidics; sepsis; size-based separation; selective cell-lysis; immune-based isolation; Biotechnology; Bioteknologi;

    Abstract : Microfluidics promises to re-shape the current health-care system by transferring diagnostic tools from central laboratories to close vicinity of the patient (point-of-care). One of the most important operational steps in any diagnostic platform is sample preparation, which is the main subject in this thesis. READ MORE

  5. 5. Nanomechanics – Quantum Size Effects, Contacts, and Triboelectricity

    University dissertation from Sundsvall : Mid Sweden University

    Author : Martin Olsen; Mittuniversitetet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; triboelectricity; adatom; ion; charge; mound; quantum size effect; triboelctric nanogenerator; TENG; wind driven; contact; nanomechanics; fri electron model; nanowire cantilever;

    Abstract : Nanomechanics is different from the mechanics that we experience in everyday life. At the nano-scale, typically defined as 1 to 100 nanometers, some phenomena are of crucial importance, while the same phenomena can be completely neglected on a larger scale. READ MORE
