  1. 1. Computational Modeling of the Vocal Tract : Applications to Speech Production

    Författare :Saeed Dabbaghchian; Olov Engwall; Sidney Fels; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vocal tract; upper airway; speech production; biomechanical model; acoustic model; vocal tract reconstruction; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : Human speech production is a complex process, involving neuromuscular control signals, the effects of articulators' biomechanical properties and acoustic wave propagation in a vocal tract tube of intricate shape. Modeling these phenomena may play an important role in advancing our understanding of the involved mechanisms, and may also have future medical applications, e. LÄS MER

  3. 2. Development of a New Biomechanical ex vivo Perfusion System - Studies on effects of biomechanical and inflammatory stress on hemostatic genes in human vascular endothelium

    Författare :Niklas Bergh; Göteborgs universitet; []
    Nyckelord :ex vivo perfusion system; biomechanical; endothelium; shear stress; tensile stress; pulsatile; TNF-α; JNK; hemostatic genes;

    Sammanfattning : The vascular endothelium is a multifunctional interface constantly exposed to biomechanical forces such as shear and tensile stress. Biomechanical stress is involved in the pathophysiological process of the vessel wall and thus affects vascular remodeling, atherosclerosis and thrombogenesis. LÄS MER

  4. 3. On a biomechanical approach to analysis of stability and load bearing capacity of oral implants

    Författare :Anders Halldin; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animal model; bone resorption; implant stability; cortical bone; viscoelastic-viscoplastic; creep remodeling; constitutive model;

    Sammanfattning : IntroductionWhen an implant is placed in the bone the body responds to thetrauma by encapsulating the implant and its survival depends onthe ability for hard tissue encapsulation. The stability of the implantduring the healing phase is essential to achieve a good result[1]. Biological, physiological and mechanical phenomena affectimplant stability. LÄS MER

  5. 4. A multi-disciplinary approach to studying performance among high-level golfers : physiological and biomechanical aspects

    Författare :James Parker; Charlotte M. Olsson; Toni Arndt; Högskolan i Halmstad; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carry distance; clubhead speed; driver performance; golf kinematics; sports performance; strength training; isokinetic training;

    Sammanfattning : In competitive golf, the player’s ability to hit the ball a long distance affects the score in a positive way. Swing kinematics is considered an important factor in driver performance; one way of improving swing kinematics is through strength and power training. LÄS MER

  7. 5. Improvements, Validation and Adaptation of a Shoulder Model

    Författare :Mohsen Makhsous; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; rhythm; physiological cross-sections; electromyography; muscle strength; coracoclavicular; shoulder model; ligament;

    Sammanfattning : A series of biomechanical investigations aimed at contributing to the understanding of shoulder function and improvements of a computer based shoulder model is presented. In the thesis the structure of shoulder models is revised. LÄS MER
