  1. 6. Competitive Learning in Robust Communication

    Författare :Petter Knagenhjelm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A modern communication system should be accurate, reliable, robust and make efficient use of the available channel. Vector quantization is beginning to prove its effectiveness for source coding in applications such as cellular mobile telephony. The design of vector quantizers is typically done by clustering methods. LÄS MER

  3. 7. On Robust LPC-spectrum Coding and Vector Quantization

    Författare :Roar Hagen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robustness against channel noise; LPC-spectrum coding; vector quantization; speech coding; linear mapping of a block code;

    Sammanfattning : Digital speech coding is concerned with representing a discrete-time speech signal with as few bits per second as possible without introducing annoying artifacts in the coded speech. Many modern speech coders are based on Linear Predictive Coding (LPC) which employ a source-filter model for speech production. LÄS MER

  4. 8. Membrane Orientation Studies with Polarized Light Spectroscopy

    Författare :Malin Ardhammar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lipid vesicle; membrane orientation; flow linear dichroism; oriented circular dichroism;

    Sammanfattning : Lipid vesicles are versatile tools in modern biophysical science. They can be used as models of the cell membrane, to examine permeability, stability and behavior of molecules in the bilayer. They may act as transporters in a pharmacological context, designed to deliver their cargo to a certain place in the patient. LÄS MER

  5. 9. Studies on energy expenditure in walking after stroke

    Författare :Anna Danielsson; Göteborgs universitet; []
    Nyckelord :gait; rehabilitation; assessment; physical therapy; oxygen consumption; body weight support; orthotic devices; physical activity;

    Sammanfattning : Aims: The aims were to assess energy expenditure during different conditions, evaluate measurement methods and assess physical activity after stroke. Methods: In total 51 persons with stroke >6 months previously (mean age 56) and 24 reference persons participated. LÄS MER

  7. 10. Modelling and Inference for Spatio-Temporal Marked Point Processes

    Författare :Ottmar Cronie; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Asymptotic normality; Consistency; Cox-Ingersoll-Ross process; Diffusion process; Edge correction; Goodness-of-fit; Richards growth function; Growth-interaction process; Immigration-death process; Least squares estimation; Markov process; Maximum likelihood estimation; Open-growth; Spatio-temporal marked point process; Stationarity; Stochastic differential equation; Transition density; Asymptotic normality;

    Sammanfattning : This thesis deals with inference problems related to the growth-interaction process (GI-process). The GI-process is a continuous time spatio-temporal point process with dynamic interacting marks (closed disks), in which the immigration-death process (ID-process) controls the arrivals of new marked points as well as their potential life-times.
