  1. 1. How About Running on Mars ? Influence of Sensory Coherence on the Running Pattern and on Spatial Perception in Simulated Reduced Gravity

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Marie Keime; [2022]
    Nyckelord :Adaptation; Gravity; Locomotion; Sensory factors; Spatial perception; Unweighting.; Rörelse; Gravitation; Anpassning; Avvägning; Sensoriska faktorer; Rumslig uppfattning.;

    Sammanfattning : Motor control, including locomotion, strongly depends on the gravitational field. Recent developments like lower-body positive pressure treadmills (LBPPTs) have enabled Earth- based studies on the effects of reduced body weight (BW) on walking and running. Yet, the observed adaptations to simulated hypogravity are not optimal. LÄS MER

  3. 2. Numerical Study on Seepage-induced Failure of Caisson Type Breakwaters Using a Stabilized ISPH

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Tetsuro Goda; [2017]
    Nyckelord :Tsunami; Breakwater; Particle method; SPH; Seepage flow; Technology and Engineering;

    Sammanfattning : This paper presents a stabilized incompressible smoothed particle hydrodynamics (ISPH) method to simultaneously simulate surface and seepage flow. The Navier-Stokes type equation, which manipulates the linear and nonlinear resistance effects caused from porous materials, are employed for tracking fluid motions in porous medium. LÄS MER

  4. 3. Numerical study on hydraulic verticallift gate during shutdown process

    Master-uppsats, KTH/Mekanik

    Författare :Mattias Sund; Fredrik Magnusson; [2014]
    Nyckelord :Computational Fluid Dynamics CFD ; High head lift gate; Down-pull force; Gate holding force; Dynamic mesh; Emergency gate shutdown.;

    Sammanfattning : China is undergoing a rapid increase in their development of hydropower.Due to this rapid increase, China has become one of theleading countries in technological solutions regarding the constructionof the hydropower plant. The hydro resources in China are extensivebut building a new power plant is laborious and costly. LÄS MER

  5. 4. Steady Periodic Water Waves Solutions Using Asymptotic Approach

    Master-uppsats, Tillämpad matematik

    Författare :Shahid Hasnain; [2011]
    Nyckelord :Steady two dimensional water wave; perturbation approach; separation of variable; pressure head and flow force.;

    Sammanfattning : The aim of this work is to study the relation between two invariants of water flow in a channel of finite depth. The first invariant is the height of the water wave and the second one is the flow force. We restrict ourselves to water waves of small amplitude. LÄS MER
